Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of International Patent Application No. PCT/CN2018/079402 with a filing date of Mar. 19, 2018, designating the United States, now pending, and further claims priority to Chinese Patent Application No. 201810038215.0 with a filing date of Jan. 16, 2018. The content of the aforementioned applications, including any intervening amendments thereto, are incorporated herein by reference.

TECHNICAL FIELD

The present application relates to a mangling device for fibers, fiber webs or analogues, which belongs to the technical field of liquid removal of textile materials.

BACKGROUND OF THE PRESENT INVENTION

Water squeezing as a critical procedure in a dyeing process is used to squeeze and dehydrate washed fibers or fiber webs and other analogues. The existing mangling machine mainly includes a pair of upper second rollers, a group of upper and lower conveyor belts and a plurality of upper and lower driving rollers. Referring to FIG. 1, an upper conveyor belt 3a is sleeved among upper driving rollers 5a; a lower conveyor belt 4a is sleeved among lower driving rollers 6a; an upper roller 1a and a second roller 2a are located in loops of the upper conveyor belt 3a and the lower conveyor belt 4a respectively; and a certain space for a fiber layer 7a to pass is reserved therebetween. When the upper and the lower conveyor belts move simultaneously, the fiber layer 7a is clamped by the upper and the lower conveyor belts to move forward. The mangling machine of this structure is convenient to use and high in processing capacity. However, since the fiber is squeezed by contact points of the upper second rollers; the pressure is mainly concentrated on the middle contact point, while two sides of the upper and the lower rollers are both in a loose state, so that a majority of water squeezed out from the fiber layer 7a may fall onto the lower conveyor belt 4a and is discharged from meshes on the lower conveyor belt 4a, but there is still some water. Since the fiber layer 7a is loosened without compression after passing through the upper second rollers, the remaining water may be absorbed into the fiber layer 7a again. Therefore, the actual dehydration rate is not high, which affects the overall dehydration effect of the fibers, the fiber layer and the analogues.

Based on this, the present application is proposed.

SUMMARY OF PRESENT INVENTION

For the above defects of the existing mangling process, the present application provides a mangling device for fibers, fiber webs or analogues, which can realize efficient dehydration and reduce the back absorption of the dehydrated water.

To realize the above purpose, the present application adopts the following technical solutions:

A mangling device for fibers, fiber webs or analogues comprises two rollers and two conveying mechanisms, and at least one of the two rollers is a driving roller. The conveying mechanism comprises at least one driving roller, a plurality of carrier rollers and guiding belts installed on the driving roller and the carrier rollers in a tensioning manner. A space which is used for the fibers, the fiber webs or the analogues to pass is arranged between the two guiding belts, and the portions of the two guiding belts forming the passing space of the fibers, the fiber webs or the analogues are parallel to each other. The two rollers are respectively installed on positions corresponding to the passing space of the two guiding belts.

Further, preferably:

At least one of the guiding belts of the two conveying mechanisms is provided with a drain passage, and preferably, the drain passage is formed by leakage holes, a water conveying channel or a moisture absorption belt. When the leakage holes, the water conveying channel, the moisture absorption belt or meshes and other structures are arranged on the guiding belt as the drain passage, the overflow of liquid such as water from the squeezed fibers or fiber webs can be facilitated, so that the separation efficiency of the liquid such as the water from the fibers or the fiber webs can be improved; or the guiding belt is set as a felt structure, a felt-like structure, a Teflon mesh or a steel wire mesh, and compared with the drain passage, the guiding belt of the felt or felt-like structure can improve the mangling effect under an extremely small force.

At least one of the two rollers is connected with a pressurizing mechanism to increase the pressure between the two rollers. Preferably, the pressurizing mechanism adopts an air cylinder (for example, the air cylinder is cooperated with a big arm, the big arm is installed between the air cylinder and the corresponding roller, and the air cylinder drives the big arm to rise and fall to drive the corresponding roller to move up and down, so that a space between the rollers is changed, that is, the pressure applied to the fibers, the fiber webs or the analogues between the two rollers is changed), an electromagnetic way, a mechanical way or a similar way to lift the corresponding rollers so as to change the pressure between the two rollers.

A water tank is arranged below the guiding belt and used to receive the water squeezed from the fibers or the fiber webs. More preferably, the water tank is located in the loop of the guiding belt. With the water tank, the environmental pollution caused by the splash of the squeezed water and the secondary pollution of the fibers, the fiber webs or the analogues can be avoided. When the water tank is arranged in the loop of the guiding belt, it is considered that the guiding belt may move from the original squeezed position to below the original squeezed position along with the rotation of the corresponding driving rollers, the squeezed and falling liquid such as the water drops onto the guiding belt and may be carried to the squeezed position again. In order to avoid the secondary dehydration caused by the carrying, the water tank is arranged in the loop of the guiding belt to prevent the water from dropping onto the guiding belt below the squeezed position, thereby improving the dehydration rate in the entire operation process.

The two rollers are arranged corresponding to each other in the vertical direction or arranged in a staggering manner. The rollers are main parts for squeezing the fibers, the fiber webs or the analogues between the guiding belts. When the two rollers are arranged corresponding to each other in the vertical direction, and when the fibers, the fiber webs or the analogues pass through the two rollers, the upper surface and the lower surface thereof are squeezed by the two rollers respectively, and the liquid such as the water is rapidly separated out from the upper surface and the lower surface. When the two rollers are arranged in a staggering manner, the fibers, the fiber webs or the analogues pass through one roller first to be primarily squeezed between the roller and the corresponding guiding belt, the liquid such as the water is squeezed out from the fibers, the fiber webs or the analogues, and then the fibers, the fiber webs or the analogues continuously pass through the second roller to be secondarily squeezed between the second roller and the guiding belt corresponding thereto, and the liquid such as the water is squeezed out from the fibers, the fiber webs or the analogues. In this way, by virtue of one-time or multi-time squeezing, the liquid such as the water can be gradually separated out from the fibers, the fiber webs or the analogues.

A tensioning wheel is installed in the loop of the guiding belt. The tensioning wheel is preferably installed on an axis perpendicular to the guiding belt and moves up and down along the axis so as to adjust the tension of the loop of the corresponding guiding belt.

A rectifying wheel is arranged in the loop of the guiding belt. The rectifying wheel is preferably arranged in a front section of the loop. In a transfer process of the fibers, the fiber webs or the analogues, along with the rotation of each roller shaft, the deviation phenomenon is likely to occur. In order to avoid the transfer mistake, the rectifying wheel is arranged in the loop of the guiding belt. The rectifying wheel is preferably arranged in the front section of the loop. The rectifying wheel is arranged near the front, so that the subsequent transfer accuracy is guaranteed.

The driving rollers in the two conveying mechanisms are respectively called the first driving roller and the second driving roller. The rollers are respectively called the first roller and the second roller. The first driving roller, the first roller, the second driving roller and the second roller are arranged according to the following way:

A pair of first driving rollers is arranged. An outer diameter of the first driving rollers is greater than that of the first roller. The guiding belt corresponding to the first driving roller is sleeved on the first driving roller. The first roller is located at the loop of one side of the guiding belt close to other guiding belt. More preferably, at least one first roller is provided. The outer diameter of the first driving roller is greater than that of the first roller. One pair of first driving rollers can satisfy the distribution of the first roller in the loop of the guiding belt thereof. This structure is convenient to operate, few in components and more stable to control.

A pair of second driving rollers is arranged. An outer diameter of the second driving rollers is greater than that of the second roller. The guiding belt corresponding to the second driving rollers is sleeved on the second driving rollers. The second roller is located at the loop of one side of the guiding belt close to other guiding belt. More preferably, at least one second roller is provided. The outer diameter of the second driving rollers is greater than that of the second roller. One pair of second driving rollers can satisfy the distribution of the second roller in the loop of the guiding belt thereof. This structure is convenient to operate, few in components and more stable to control.

A plurality of first driving rollers (≥3) are provided. The guiding belt corresponding to the first driving rollers is sleeved on a closed path formed by the plurality of first driving rollers. The first roller is located at the loop of one side of the guiding belt close to the other guiding belt. More preferably, at least one first roller is provided. The plurality of first driving rollers can form a structure with a large space in the guiding belt. When the first rollers are distributed in the loop of the guiding belt, there is no need to consider the size requirements of the first driving rollers and the first roller, so that the operation is more flexible, the replaceability and the universality are better, and the control is more stable.

A plurality of second driving rollers (≥3) are provided. The guiding belt corresponding to the second driving rollers is sleeved on a closed path formed by the plurality of second driving rollers. The second roller is located at the loop of one side of the guiding belt close to the other guiding belt. More preferably, at least one second roller is provided. The plurality of second driving rollers can form a structure with a large space in the guiding belt. When the second rollers are distributed in the loop of the guiding belt, there is no need to consider the size requirement of the second driving rollers and the second roller, so that the operation is more flexible, the replaceability and the universality are better, and the control is more stable.

The present application is applied to the separation of the liquid such as water from the fibers, the fiber webs or the analogues; the two guiding belts are driven by the driving rollers to rotate; the fibers, the fiber webs or the analogues are clamped by the two guiding belts to move forwards under the relative motion of the two guiding belts; and when the fibers, the fiber webs or the analogues pass through the two rollers, the liquid such as the water can be separated out in one step or can be gradually separated out in multiple steps through the cooperation of the two rollers and the cooperation of the rollers and the corresponding guiding belts. In this process, the fibers are always in a squeezed state when entering between the two guiding belts, that is, the separation of the liquid such as the water is not only limited to the contact position of the two rollers, but also enlarged to between different rollers and different guiding belts, so that the back absorption of the liquid such as the water caused by the reduction of the pressure can be avoided.

Embodiment 8

The present embodiment has the same setup and working principle with that of embodiment 1, and differs in that: as shown in FIG. 8, a tensioning roller is installed in the loop of the guiding belt, i.e. an upper tensioning wheel 54 and a lower tensioning roller 66 in FIG. 8.

Embodiment 9

The present embodiment has the same setup and working principle with that of embodiment 1, and differs in that: a least one of the two rollers is connected with a pressurizing mechanism so as to increase the pressure between the two rollers.

Preferably, the pressurizing mechanism adopts an air cylinder (as shown in FIG. 10; the air cylinder (not shown in the figure) is cooperated with a big arm 16; the big arm 16 is installed between the air cylinder and the corresponding first roller 1; the air cylinder drives the big arm 16 to rise and fall to drive the first roller 1 to move up and down, so that the space between the two rollers is changed, that is, the pressure applied to the fibers, the fiber webs or the analogues between the two rollers is changed), an electromagnetic way, a mechanical way or a similar way to lift the corresponding rollers so as to change the pressure between the two rollers.

In each of the above solutions, a water tank 8 can also be arranged below the guiding belt II 4 and used to receive the water squeezed from the fibers or the fiber webs. More preferably, the water tank 8 is located in the loop of the guiding belt II 4. With the water tank 8, the environmental pollution caused by the splash of the squeezed water and the secondary pollution of the fibers, fiber webs or analogues can be avoided. When the water tank 8 is arranged in the loop of the guiding belt II 4, it is considered that the guiding belt II 4 may move from the original squeezed position to be below the original squeezed position along with the rotation of the second driving rollers 6, the squeezed and falling liquid such as the water drops onto the guiding belt II 4 and may be carried to the squeezed position again. In order to avoid the secondary dehydration caused by the carrying, the water tank is arranged in the loop of the guiding belt to prevent the water from dropping onto the guiding belt II 4 below the squeezed position, thereby improving the dehydration rate in the entire operation process.

In each of the above solutions, the guiding belt I 3 and/or the guiding belt II 4 is only used for conveying, and the guiding belt I 3 and/or the guiding belt II 4 may also be provided with a drain mechanism formed by meshes, leakage holes, a water conveying channel or a moisture absorption belt. The guiding belt I 3 and the guiding belt II 4 are cooperated to clamp and convey the fibers, the fiber webs or the analogues. When the drain mechanism is arranged thereon, the overflow of the liquid such as the water from the squeezed fibers or fiber webs can be facilitated, thereby improving the separation efficiency of the liquid such as the water from the fibers or the fiber webs. According to the use requirement, the guiding belt I 3 and/or the guiding belt II 4 may also select a second solution: the guiding belt I 3 and/or the guiding belt II 4 selects a felt structure, a felt-like structure, a Teflon mesh or a steel wire mesh, so that the mangling effect can be improved under an extremely small acting force.

In each of the above solutions, the first roller 1 and the second roller 2 are arranged vertically in a corresponding manner or in a staggering manner. The first roller 1 and the second roller 2 are main parts for squeezing the fibers, the fiber webs or analogues between the guiding belt and the mesh belt. When the first roller 1 and the second roller 2 are arranged vertically in a corresponding manner as shown in FIG. 2-FIG. 7, and when the fibers, the fiber webs or the analogues pass through the first roller 1 and the second roller 2, the upper surface and lower surface thereof are squeezed by the first roller 1 and the second roller 2 respectively, and the liquid such as the water is rapidly separated from the upper surface and lower surface. When the first roller 1 and the second roller 2 are arranged vertically in a staggering manner, the fibers, the fiber webs or the analogues pass through the first roller 1/the second roller 2 first to be primarily squeezed between the first roller 1/the second roller 2 and the guiding belt II 4/the guiding belt I 3, and the liquid such as the water is squeezed out from the fibers, the fiber webs or the analogues, and then the fibers, the fiber webs or the analogues continuously pass through the second roller 2/the first roller 1 to be secondarily squeezed between the second roller 2/the first roller 1 and the guiding belt I 3/the guiding belt II 4, and the liquid such as the water is squeezed out from the fibers, the fiber webs or the analogues. In this way, by virtue of one-time or multi-time squeezing, the liquid such as the water is gradually separated from the fibers, the fiber webs or the analogues.

The present application is applied to the separation of the liquid such as water from the fibers, the fiber webs or the analogues. The guiding belt I 3 is driven by the first driving rollers 5 to rotate; the guiding belt II 4 is driven by the second driving rollers 6 to rotate; and the fibers, and the fiber webs or the analogues are clamped by the guiding belt I 3 and the guiding belt II 4 to move forwards under the relative motion of the two. When the fibers, the fiber webs or the analogues pass through the first roller 1 and the second roller 2, the liquid such as the water can be separated in one step or gradually separated in multiple steps through the cooperation of the first roller 1 and the second roller 2 and the cooperation of the first roller 1 and the guiding belt II 4 or the second roller 2 and the guiding belt I 3. In this process, the fibers are always in a squeezed state when entering between the guiding belt I 3 and the guiding belt II 4, that is, the separation of the liquid such as the water is not only limited to the contact position of the first roller 1 and the second roller 2, but also enlarged to between the first roller 1 and the guiding belt II 4 and between the second roller 2 and the guiding belt I 3, so that the back absorption of the liquid such as the water caused by the reduction of the pressure can be avoided.

The above description is further detailed description of the provided technical solutions in conjunction with the preferred embodiments of the present invention. It shall not be assumed that the specific implementation of the present invention is limited to the above descriptions. For those ordinary skilled in the prior art, several simple deductions or substitutions may be made without deviating from the inventive concept of the present invention, and shall all be regarded as falling within the protection scope of the present invention.
