Description

CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority to Chinese Patent Application No. 202311198886.0, filed on Sep. 18, 2023, which is herein incorporated by reference in its entirety.

TECHNICAL FIELD

The disclosure relates to the field of textile technologies, and more particularly to a pipeline-type positive warp yarn feeding device.

BACKGROUND

In the textile industry, a warp yarn feeding process has a significant impact on quality of weaving and production efficiency. Yarn feeding mechanisms in the related art generally rely directly on rotation of rollers to drive yarns on a yarn frame. These methods in the related art have some limitations, such as easily causing gears on a roller speed change mechanism that drives the rotation of the rollers on the yarn frame device to be subjected to large forces, making it difficult to achieve stable yarn supply. Alternatively, different yarn paths experience different friction and traction forces, resulting in unstable passive tension of the yarns, which can easily lead to production interruptions caused by breakage. Continuous and stable yarn feeding is conducive to preform forming and weaving.

A patent literature with application No. CN201821990607.9 (corresponding to the publication No. CN209161155U) provides a passive warp yarn feeding device, which includes a positioning shaft. Two ends of the positioning shaft are fixedly arranged on a production line of a webbing machine. A yarn spindle is sleeved on the positioning shaft. The passive warp yarn feeding device also includes an end positioning mechanism, which is sleeved on the positioning shaft and an axial position of the end positioning mechanism on the positioning shaft is fixed and unchanged. A part of a structure of the end positioning mechanism is inserted into a yarn spindle paper core and abuts against an end and inside of the yarn spindle paper core. By setting up the end positioning mechanism on the yarn spindle paper core, and with the part of the structure of the end positioning mechanism inserted inside the yarn spindle paper core, relative firmness of the yarn spindle paper core during rotation is ensured. Even when the yarns are drawn radially, the yarn spindle paper core will not shake, improving stability of a drawing process and fully ensuring product quality. However, the passive warp yarn feeding method can produce different tension effects on the yarns in different yarn paths, making it difficult to ensure consistent feeding tension of the yarns, and thus unable to ensure stable supply and synchronous feeding of the yarns.

SUMMARY

In order to overcome problem in the related art, the disclosure provides a pipeline-type positive warp yarn feeding device, ensuring stable supply and synchronous conveyance of yarn through positive yarn feeding, avoiding impact of different yarn conveying paths on yarn tension.

To solve above technical problem, the disclosure has the following technical solutions: the pipeline-type positive warp yarn feeding device includes a yarn bobbin frame and a yarn feeding frame. The yarn feeding frame is provided with a positive yarn feeding assembly thereon, the positive yarn feeding assembly includes a positive yarn feeding power component and positive yarn feeding wheels disposed on the yarn feeding frame. The positive yarn feeding wheels are in one-to-one correspondence with yarn bobbins on the yarn bobbin frame. An outer circumference surface of a wheel shaft of each positive yarn feeding wheel defines yarn feeding grooves with a spiral shape, and a groove mouth width of each yarn feeding groove is matched with a width of a strand of yarn. The yarn on the yarn bobbins is wound on the positive yarn feeding wheels. Each yarn feeding groove is configured to accommodate only a corresponding strand of the yarn. The positive yarn feeding power component is configured to drive the positive yarn feeding wheels to rotate and feed the yarn through a transmission gear assembly.

In an embodiment, the yarn feeding frame is provided with multiple yarn feeding shafts, each yarn feeding shaft is provided with corresponding positive yarn feeding wheels, and the corresponding positive yarn feeding wheels are capable of rotating with the yarn feeding shaft.

In an embodiment, a side of each positive yarn feeding wheel is provided with a wheel shaft clutch, and the wheel shaft clutch is configured to drive the corresponding positive yarn feeding wheel to rotate with a corresponding yarn feeding shaft.

In an embodiment, a key pin limiting component is disposed between each wheel shaft clutch and the corresponding yarn feeding shaft, and the key pin limiting component is configured to restrict each wheel shaft clutch to only make axial displacement movements along the corresponding yarn feeding shaft.

In an embodiment, an inner ring bearing of each positive yarn feeding wheel is sleeved on the corresponding yarn feeding shaft.

In an embodiment, a yarn feeding positioning component is disposed between each positive yarn feeding wheel and a corresponding yarn bobbin, the yarn feeding positioning component is disposed near a yarn entry end of the positive yarn feeding wheel and faces towards a winding travel starting end of the positive yarn feeding wheel, and the yarn passes through the yarn feeding positioning component from the winding travel starting end of the positive yarn feeding wheel to a winding travel ending end of the positive yarn feeding wheel.

In an embodiment, yarn feeding pipes are disposed between the yarn bobbin frame and the yarn feeding frame, and the yarn feeding pipes extend from yarn outlet ends of the yarn bobbins to yarn entry ends of the positive yarn feeding wheels.

In an embodiment, the yarn bobbin frame is disposed at a side of the yarn feeding frame, the yarn feeding pipes extend horizontally from the yarn outlet ends of the yarn bobbins to the side of the yarn feeding frame, and then vertically turn at horizontal positions corresponding to the positive yarn feeding wheels to extend to the yarn entry ends of the positive yarn feeding wheels.

In an embodiment, a turning point of each yarn feeding pipe defines a ceramic yarn feeding eyelet.

In an embodiment, a yarn outlet end of each positive yarn feeding wheel is provided with a yarn breakage automatic stopper, and the yarn breakage automatic stopper is disposed facing towards the winding travel ending end of the positive yarn feeding wheel.

The disclosure has beneficial effects as follows.

The disclosure defines the spiral yarn feeding grooves on the outer circumference surfaces of the wheel shafts of the positive yarn feeding wheels. The groove mouth width of each yarn feeding groove is matched with the width of a single strand of the yarn. The yarn from the yarn bobbins wraps around the positive yarn feeding wheels along the spiral yarn feeding grooves. Only one strand of the yarn is accommodated within a single yarn feeding tooth groove. Under the limiting and traction action of the yarn feeding grooves, the yarn realizes single-layer sequential winding along the spiral yarn feeding grooves on the wheel shafts of the positive yarn feeding wheels, avoiding problem of yarn layering on the positive yarn feeding wheels that causes the yarn to-be-output to be laminated and results in unsmooth yarn feeding, facilitating continuous and stable yarn supply.

The positive yarn feeding power component described in the disclosure is configured to drive the positive yarn feeding wheels to rotate and feed the yarn through the transmission gear assembly. Under rotational power provided by the positive yarn feeding power component, the positive yarn feeding wheels positively feed the yarn, ensuring stable supply and synchronous delivery of the yarn, and also avoiding influence of different yarn feeding paths on yarn tension. Furthermore, by setting the number of teeth that match between a first driven gear and a second driven gear, a rotational speed of different yarn feeding shafts can be controlled separately, achieving that a single drive motor can simultaneously control the positive yarn feeding wheels with different yarn feeding amounts to perform the yarn feeding work.

In the disclosure, the yarn feeding pipes are disposed between the yarn bobbin frame and the yarn feeding frame, changing an output path of the yarn, thereby changing a position of the yarn bobbin frame relative to the yarn feeding frame, so as to achieve an arrangement of the yarn bobbin frame and the yarn feeding frame within a limited space. In addition, by guiding the yarn from the yarn bobbins to the positive yarn feeding wheels through the yarn feeding pipes, it can prevent yarn lint floating in the air from falling onto the yarn and affecting effects of yarn-made products.

In the disclosure, the wheel shaft clutch is configured to drive the positive yarn feeding wheel to rotate with the corresponding yarn feeding shaft. A state coordination between the positive yarn feeding wheel and the corresponding yarn feeding shaft is changed by the wheel shaft clutch. When the wheel shaft clutch is axially snap-fitted to a side of the positive yarn feeding wheel, a limit clip of the positive yarn feeding wheel is snap-fitted with a limit sleeve of the wheel shaft clutch, so as to form an integrated structure between the wheel shaft clutch and the positive yarn feeding wheel. Under the restriction of the key pin limiting component, the wheel shaft clutch drives the positive yarn feeding wheel to perform synchronous rotation with the corresponding yarn feeding shaft. When the wheel shaft clutch is separated from the positive yarn feeding wheel, a structural restriction between the positive yarn feeding wheel and the corresponding yarn feeding shaft is released, so as to allow the positive yarn feeding wheel to rotate freely on the corresponding yarn feeding shaft and to rewind a single broken yarn into the yarn feeding grooves of the positive yarn feeding wheel without the need for manual winding, thereby improving efficiency of broken yarn handling.

In the disclosure, the yarn feeding positioning component is disposed near the yarn entry end of the positive yarn feeding wheel and faces towards the winding travel starting end of the positive yarn feeding wheel, and a yarn guide component is disposed facing towards the winding travel ending end of each positive yarn feeding wheel, ensuring that the yarn always starts winding from a same position onto the positive yarn feeding wheel, and, under traction of the yarn feeding path, unwinds from a same position of the positive yarn feeding wheel. This further ensures that the yarn always maintains a single-layer sequential winding path on the shaft of the positive yarn feeding wheel, thereby ensuring a continuous and stable yarn supply path.

DETAILED DESCRIPTION OF EMBODIMENTS

The preferred embodiments of the disclosure are described in detail with reference to the accompanying drawings, in order to facilitate the understanding of advantages and features of the disclosure by those skilled in the art, and to provide a clearer and more precise definition of the scope of protection of the disclosure.

The disclosure provides a pipeline-type positive warp yarn feeding device, as shown in FIG. 1 to FIG. 7, the pipeline-type positive warp yarn feeding device includes a yarn bobbin frame 1 and a yarn feeding frame 2. The yarn feeding frame 2 is provided with a positive yarn feeding assembly thereon, and the positive yarn feeding assembly includes a positive yarn feeding power component 3 and positive yarn feeding wheels 22 disposed on the yarn feeding frame 2, the positive yarn feeding wheels 22 are in one-to-one correspondence with yarn bobbins 11 on the yarn bobbin frame 1. An outer circumference surface of a wheel shaft of each positive yarn feeding wheel 22 defines yarn feeding grooves 221 with a spiral shape. A groove mouth width of each yarn feeding groove 221 is matched with a width of a strand of yarn. The yarn on the yarn bobbins 11 is wound on the positive yarn feeding wheels 22, and each yarn feeding groove is configured to accommodate only a corresponding strand of the yarn. Under the limiting and traction action of the yarn feeding grooves 221, the yarn is wound in a single layer in sequence along the yarn feeding grooves 221 with the spiral shape on the wheel shafts of the positive yarn feeding wheels 22, avoiding problem of yarn layering on the positive yarn feeding wheels 22 that causes the yarn to be laminated and leads to unsmooth yarn feeding, facilitating continuous and stable yarn supply. The positive yarn feeding power component 3 is configured to drive the positive yarn feeding wheels 22 to rotate and feed the yarn through a transmission gear assembly. Under rotational power provided by the positive yarn feeding power component 3, the positive yarn feeding wheels 22 positively feed the yarn, ensuring stable supply and synchronous delivery of the yarn, and also avoiding influence of different yarn feeding paths on yarn tension.

As shown in FIG. 1 to FIG. 3, the yarn bobbin frame 1 is provided with the multiple yarn bobbins 11. The yarn feeding frame 2 is provided with multiple yarn feeding shafts 21 sequentially arranged in that order from top to bottom, each yarn feeding shaft 21 is provided with multiple positive yarn feeding wheels 22, and the positive yarn feeding wheels 22 are in one-to-one correspondence with the yarn bobbins 11 on the yarn bobbin frame 1. In order to further save the space occupied by the yarn bobbin frame 1 and the yarn feeding frame 2, as shown in FIG. 1 and FIG. 2, the yarn bobbin frame 1 can be placed on a side of the yarn feeding frame 2, and the yarn from the yarn bobbins 11 is guided to the positive yarn feeding wheels 22 through the yarn feeding pipes 4. The yarn feeding pipes 4 are disposed between the yarn bobbin frame 1 and the yarn feeding frame 2, and the yarn feeding pipes 4 extend from yarn outlet ends of the yarn bobbins 11 to yarn entry ends of the positive yarn feeding wheels 22. Specifically, the yarn feeding pipes 4 extend horizontally from the yarn outlet ends of the yarn bobbins 11 to the side of the yarn feeding frame 2, and vertically turn at horizontal positions corresponding to the positive yarn feeding wheels 22 to extend to the yarn entry ends of the positive yarn feeding wheels 22, and a turning point of each yarn feeding pipe 4 defines a ceramic yarn feeding eyelet. By setting up the yarn feeding pipes 4 between the yarn bobbin frame 1 and the yarn feeding frame 2, an output path of the yarn is changed, and a relative position of the yarn bobbin frame 1 to the yarn feeding frame 2 is changed, achieving an arrangement of the yarn bobbin frame 1 and the yarn feeding frame 2 within a limited space. In addition, by guiding the yarn from the yarn bobbins 11 to the positive yarn feeding wheels 22 through the yarn feeding pipes 4, it can prevent yarn lint floating in the air from falling on the yarn and affecting effects of yarn products.

A side of the yarn feeding frame 2 is provided with the positive yarn feeding power component 3. The positive yarn feeding power component 3 includes a drive motor 31, a main drive gear 32, multiple first driven gears 34, and multiple second driven gears 35, as shown in FIG. 1. The main drive gear 32 is coaxially arranged at a power output end of the drive motor 31. The yarn feeding shafts 21 on the yarn feeding frame 2 protrude from one end on a same side through the yarn feeding frame 2, and a protruding end of each yarn feeding shaft 21 is coaxially provided with a corresponding second driven gear 35. The side of the yarn feeding frame 2 facing towards the second driven gears 35 is vertically provided with a transmission shaft 33. The multiple first driven gears 34 are coaxially mounted on the transmission shaft 33 from top to bottom. The first driven gears 34 are meshed and connected to the second driven gears 35 in a one-to-one correspondence, and at least one of the first driven gears 34 is meshed and connected to the main drive gear 32.

The drive motor 31 drives the at least one first driven gear 34 meshed with the main drive gear 32 to rotate through the main drive gear 32. The at least one first driven gear 34 drives all other first driven gears 34 to rotate through the transmission shaft 33, thereby driving the second driven gears 35 meshed with the other first driven gears 34 to rotate. The second driven gears 35 correspondingly drive the yarn feeding shafts 21 to rotate. The positive yarn feeding wheels 22 are coaxially fixed on the yarn feeding shafts 21, and can rotate correspondingly with the yarn feeding shafts 21 to achieve positive yarn feeding.

Preferably, in an actual textile process, if a yarn feeding amount per unit time for different yarn is different, a rotation speed of each yarn feeding shaft 21 can be controlled by setting the number of teeth that match between each second driven gear 35 and a corresponding first driven gear 34, so as to realize that the drive motor 31 simultaneously control the positive yarn feeding wheels 22 with different yarn feeding amounts to perform the yarn feeding work.

The positive yarn feeding wheels 22 are coaxially fixed on the yarn feeding shafts 21 and rotates with the yarn feeding shafts 21 through wheel shaft clutches 23. As shown in FIG. 4 and FIG. 6, an inner ring bearing 223 of each positive yarn feeding wheel 22 is sleeved onto a corresponding yarn feeding shaft 21, and a side of each positive yarn feeding wheel 22 is provided with a wheel shaft clutch 23 to drive the positive yarn feeding wheel 22 to rotate with the corresponding yarn feeding shaft 21. As shown in FIG. 6, a side of each positive yarn feeding wheel 22 opposite to the wheel shaft clutch 23 is provided with a limit clip 222 arranged circumferentially, and a side of the wheel shaft clutch 23 facing towards the positive yarn feeding wheel 22 is provided with a limit sleeve 231 arranged circumferentially. The limit clip 222 and the limit sleeve 231 are circumferentially matched to combine the wheel shaft clutch 23 with the positive yarn feeding wheel 22. Meanwhile, each yarn feeding shaft 21 is provided with a key pin limiting component 211, and an inner ring of the wheel shaft clutch 23 is provided with a key pin limit sleeve 232. The key pin limiting component 211 and the key pin limit sleeve 232 are matched to restrict the wheel shaft clutch 23 to only make axial movements along the corresponding yarn feeding shaft 21 and to synchronize a rotation of the wheel shaft clutch 23 with the corresponding yarn feeding shaft 21.

A state coordination between the positive yarn feeding wheel 22 and the corresponding yarn feeding shaft 21 is changed by the wheel shaft clutch 23. When the wheel shaft clutch 23 is axially snap-fitted to a side of the positive yarn feeding wheel 22, the limit clip 222 of the positive yarn feeding wheel 22 is snap-fitted with the limit sleeve 231 of the wheel shaft clutch 23, so as to form an integrated structure between the wheel shaft clutch 23 and the positive yarn feeding wheel 22. Under the restriction of the key pin limiting component 211, the wheel shaft clutch 23 drives the positive yarn feeding wheel 22 to perform synchronous rotation with the corresponding yarn feeding shaft 21. When the wheel shaft clutch 23 is separated from the positive yarn feeding wheel 22, a structural restriction between the positive yarn feeding wheel 22 and the corresponding yarn feeding shaft 21 is released, so as to allow the positive yarn feeding wheel 22 to rotate freely on the corresponding yarn feeding shaft 21 and to rewind a single broken yarn into the yarn feeding grooves 221 of the positive yarn feeding wheel 22 without the need for manual winding, thereby improving efficiency of broken yarn handling.

The yarn wraps around the positive yarn feeding wheels 22 along the yarn feeding grooves 221 from the yarn entry ends of the positive yarn feeding wheels 22, and then unwinds from the yarn outlet ends of the positive yarn feeding wheels 22. To ensure that the yarn always maintains a same winding path on the positive yarn feeding wheels 22, as shown in FIG. 3, a yarn feeding positioning component 5 is disposed between each positive yarn feeding wheel 22 and a corresponding yarn bobbin 11. The yarn feeding positioning component 5 is disposed near the yarn entry end of the positive yarn feeding wheel 22 and faces towards a winding travel starting end of the positive yarn feeding wheel 22. The yarn passes through the yarn feeding positioning component 5 and then wraps from the winding travel starting end to the winding travel ending end of the positive yarn feeding wheel 22. The yarn feeding positioning component 5 ensures that the yarn always starts winding from a same position onto the positive yarn feeding wheel 22, and, under traction of the yarn feeding path, unwinds from a same position of the positive yarn feeding wheel 22. This further ensures that the yarn always maintains a single-layer sequential winding path on the shaft of each positive yarn feeding wheel 22, thereby ensuring a continuous and stable yarn supply path.

As shown in FIG. 2, FIG. 3 and FIG. 7, the yarn outlet end of each positive yarn feeding wheel 22 is provided with a yarn breakage automatic stopper 6. The yarn breakage automatic stopper 6 is provided with yarn guide components 61 (also referred to as yarn feeding eyelets) and a tension regulator 62. The yarn guide components 61 are disposed facing towards the winding travel ending end of the positive yarn feeding wheel 22 to guide the yarn to be unwound from the winding travel ending end of the positive yarn feeding wheel 22, ensuring the yarn winding path on the positive yarn feeding wheel 22 from the yarn outlet end and ensuring smooth yarn feeding. The tension regulator 62 has a certain elastic tension. The yarn passes over the tension regulator 62, and the elastic tension is used to adjust a tension on the yarn feeding path, avoiding jitter and disorder of the yarn, thereby reducing a risk of yarn damage or yarn breakage. Furthermore, the yarn breakage automatic stopper 6 is provided with an alarm light 63. A control switch of the alarm light 63 is electrically connected to a controller of the yarn breakage automatic stopper 6. When the yarn breakage automatic stopper 6 detects that the yarn on the yarn feeding path is broken, the alarm light 63 lights up, helping an operator to promptly locate the broken yarn path. In addition, the yarn breakage automatic stopper 6 is provided with a tension clamping board 64 facing towards the winding travel ending end of the positive yarn feeding wheel 22, and the tension clamping board 64 is configured to control yarn tension. The yarn breakage automatic stopper 6 is further provided with a tension adjustment screw 65 disposed at a same side as the alarm light 63. An electrical connector rod 66 and a clamping plate 67 are disposed at a bottom of the yarn breakage automatic stopper 6, and the clamping plate 67 is configured to fix the yarn breakage automatic stopper 6.

The yarn is drawn from the yarn bobbins 11 on the yarn bobbin frame 1, and guided through the yarn feeding pipes 4 to the yarn feeding frame 2. After through the yarn feeding pipes 4, the yarn passes through the yarn feeding positioning components 5, and then wraps around the positive yarn feeding wheels 22 from the yarn entry ends along the yarn feeding grooves 221. The yarn wraps from the winding travel starting ends of the positive yarn feeding wheels 22 to the winding travel ending ends, and then unwinds from the yarn outlet ends of the positive yarn feeding wheels 22. Then, the yarn passes through the yarn breakage automatic stoppers 6 followed by entering a textile machine for weaving.

The pipeline-type positive warp yarn feeding device provided by the disclosure has excellent yarn feeding control capabilities. Users can easily adjust the yarn feeding amount according to actual needs to meet requirements of different textile processes. The yarn feeding amount has a very wide range, from s slowest setting, where only 1 meter of the yarn is fed in 4-5 hours, suitable for occasions that require fine textile operations or have special requirements for yarn supply. Meanwhile, the pipeline-type positive warp yarn feeding device also has outstanding production capacity. When a large amount of yarn is needed, it can be easily adjusted to a fastest mode, with the yarn feeding amount up to 40-50 meters per hour. It is very useful for high-yield textile production environments and can significantly improve production efficiency.

The above are only an embodiment of the disclosure and do not limit the patent scope of the disclosure.
