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 FIELDThe disclosure relates to the field of textile technologies, and more particularly to a pipeline-type positive warp yarn feeding device.
BACKGROUNDIn 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.
SUMMARYIn 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 EMBODIMENTSThe 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
As shown in
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
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
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
As shown in
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. Any equivalent structure or equivalent process transformation made using the content of the specification and drawings of the disclosure, or directly or indirectly applied in other related technical fields, are equally included within the patent protection scope of the disclosure.
