Description

Technical Field

[0001] This application relates to the field of warping machines, and more particularly to a tension adjustment mechanism for warping machines. Background Technology

[0002] Warping machines are key equipment in the textile industry used for warp preparation. Their core function is to draw a certain number of yarns from the bobbins, arrange them evenly and parallelly according to the required length, width, and tension, and wind them onto the warp beam. This provides a warp package that meets quality standards for subsequent weaving or dyeing and finishing processes. The tension adjustment mechanism of the warping machine is used to adjust the tension of the yarns to ensure that the yarn tension on the warp beam is consistent, and it is a key component for warping quality.

[0003] Currently, a tension mechanism for a warping machine, with publication number CN210796779U, includes a baffle with magnetic holes and a wheel seat fixedly connected to the baffle. Three tension wheels are rotatably connected to the wheel seat, and the three tension wheels are distributed in an equilateral triangle. Grooves and adjustment slots are vertically distributed on the wheel seat. Adjustment wheels are symmetrically distributed inside the grooves. A threaded rod is rotatably connected inside the adjustment slot, and a slider is threadedly connected to the outside of the threaded rod; it has the effect of adjusting the tension.

[0004] When the positions of the two adjusting wheels change, the wrap angle of the yarn around the tension wheel will change. When the wrap angle is too small, the friction between the tension wheel and the warp is insufficient, and the tension wheel cannot rotate with the warp. Slippage and friction occur between the tension wheel and the warp, which will cause the warp surface to heat up or even wear down, resulting in a decrease in the quality of the warp surface. Utility Model Content

[0005] In order to reduce the slippage and friction of warp yarns relative to the tension wheel, thereby improving the quality of warp yarns, this application provides a tension adjustment mechanism for a warping machine.

[0006] This application provides a tension adjustment mechanism for a warping machine, which adopts the following technical solution:

[0007] A tension adjustment mechanism for a warping machine includes a support plate, three tension wheels, and an adjustment device. The three tension wheels are arranged in an equilateral triangle. The tension wheels are slidably connected to the end face of the support plate along the outer center of the equilateral triangle. The adjustment device is used to simultaneously change the size of the equilateral triangle formed by the three tension wheels, and the yarn passes around the three tension wheels in sequence.

[0008] By adopting the above technical solution, and by synchronously adjusting the size of the equilateral triangle formed by the three tension wheels, the wrap angle between the yarn and the three tension wheels can remain unchanged when the tension is changed; at the same time, the synchronous scaling of the equilateral triangle structure can ensure the consistency of yarn tension adjustment and improve the warping quality.

[0009] Optionally, the adjusting device includes three sliding blocks, three connecting rods, a screw, and a connecting block. The three sliding blocks correspond to three tension wheels. The sliding blocks are slidably connected to the support plate along the direction from the circumcenter of the equilateral triangle to the corresponding tension wheel. The tension wheels are rotatably connected to the sliding blocks. The screw is located at the circumcenter of the equilateral triangle. The length direction of the screw is perpendicular to the end face of the support plate. The screw is rotatably connected to the support plate. The connecting block is threadedly connected to the screw. The three connecting rods correspond to the three sliding blocks. One end of the connecting rod is rotatably connected to the sliding block, and the other end of the connecting rod is rotatably connected to the connecting block.

[0010] By adopting the above technical solution, the synchronous and symmetrical sliding of the three tension wheels is achieved through the linkage structure of the screw, connecting block and connecting rod, ensuring the stability of the geometric shape of the equilateral triangle, reducing the imbalance of the wrap angle caused by the deviation of a single tension wheel during the adjustment process, resulting in high adjustment efficiency and more precise changes in the position of the tension wheels, further ensuring uniform yarn tension.

[0011] Optionally, the screw is provided with a rotating handle, and the rotating handle is provided with anti-slip texture in the circumferential direction.

[0012] By adopting the above technical solution, the rotating handle is easy to operate and adjust manually, the anti-slip texture increases the friction of the hand, avoids slipping during adjustment, improves the convenience and stability of operation, and reduces the tension adjustment deviation caused by operational errors.

[0013] Optionally, the adjusting device further includes a locking nut, which is threaded onto the screw and used to abut against the connecting block.

[0014] By adopting the above technical solution, after adjustment, the locking nut can fix the position of the connecting block, prevent the tension wheel from shifting due to accidental rotation of the screw caused by external forces such as vibration, ensure the stability after tension adjustment, and avoid yarn tension fluctuations affecting the warping quality.

[0015] Optionally, the three tension wheels are a first tension wheel, a second tension wheel, and a third tension wheel. The yarn passes around the first tension wheel, the second tension wheel, and the third tension wheel in sequence. The distance from the first tension wheel, the second tension wheel, and the third tension wheel to the support plate increases in sequence, so that the yarn's entry end and output end are staggered.

[0016] By adopting the above technical solution, the height difference design of the tension wheel makes the yarn winding path staggered and meandering, increasing the contact length and wrap angle between the yarn and the tension wheel, and improving the stability of friction. At the same time, the staggered entry and exit ends can reduce mutual interference when the yarn winds around, prevent the yarn from tangling or deviating, and ensure tension uniformity.

[0017] Optionally, the support plate is provided with a limiting plate, and the limiting plate has a limiting hole for guiding the yarn around the first tension wheel.

[0018] By adopting the above technical solution, the limiting hole can accurately guide the yarn into the first tension wheel, avoiding changes in the wrap angle caused by yarn deviation or friction with other components, ensuring the stability of the yarn winding path, and further guaranteeing the consistency of tension adjustment.

[0019] Optionally, both ends of the limiting hole are rounded.

[0020] By adopting the above technical solution, rounded corners can eliminate the sharp edges of the limiting hole, reduce frictional damage when the yarn passes through, protect the surface quality of the warp yarn, and avoid the problem of warp yarn wear in the background technology.

[0021] Optionally, a guide wheel is disposed on the sliding block corresponding to the first tension wheel, and the guide wheel is rotatably connected to the corresponding sliding block. The guide wheel facilitates guiding the yarn passing through the limiting hole to wind around the first tension wheel at the same angle.

[0022] By adopting the above technical solution, the guide wheel ensures that the angle at which the yarn winds into the first tension wheel is stable. Even if the position of the tension wheel changes due to adjustment, the winding angle remains consistent, thereby ensuring the stability of the wrap angle and avoiding changes in friction and tension imbalance caused by angle fluctuations.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By synchronously adjusting the positions of three tension wheels distributed in an equilateral triangle, the wrap angle between the yarn and each tension wheel can be kept stable, preventing the tension wheel from slipping and rubbing against the warp yarn due to an excessively small wrap angle; at the same time, the rounded corner treatment of the limiting hole can reduce frictional damage when the yarn passes through, protecting the surface quality of the warp yarn.

[0025] 2. The adjusting device achieves synchronous and symmetrical sliding of the three tension wheels through the linkage structure of the screw, connecting block and connecting rod, ensuring the stability of the equilateral triangle structure and avoiding tension imbalance caused by the deviation of a single wheel; in addition, the guide wheel and the limiting hole can stabilize the yarn winding path and angle, further ensuring consistent yarn tension and providing warp yarn that meets quality standards for subsequent weaving or dyeing and finishing processes.

[0031] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail.

[0032] This application discloses a tension adjustment mechanism for a warping machine. (Refer to...) Figure 1 and Figure 2 A tension adjustment mechanism for a warping machine includes a support plate 1, three tension wheels 2, and an adjustment device 3. The three tension wheels 2 are arranged in an equilateral triangle. The adjustment device 3 is used to change the size of the equilateral triangle formed by the three tension wheels 2. The yarn passes around the three tension wheels 2 in sequence. The tension wheels 2 are provided with guide grooves to restrict the yarn from falling off.

[0033] Reference Figure 2 and Figure 3 The adjusting device 3 includes three sliding blocks 31, three connecting rods 32, a screw 33, a connecting block 34, and a locking nut 35. The three sliding blocks 31 correspond to the three tension wheels 2. The three sliding blocks 31 are slidably connected to the end face of the support plate 1 along the line connecting the vertex of the equilateral triangle to the center of the circumcircle. The axis of the tension wheel 2 is perpendicular to the end face of the support plate 1, and the axes of the three tension wheels 2 are parallel to each other. The tension wheels 2 are rotatably connected to the sliding blocks 31. The length direction of the screw 33 is parallel to the axis direction of the tension wheel 2, and one end of the screw 33 is rotatably connected to... On the support plate 1, the connecting block 34 is threaded to the screw 33. Three connecting rods 32 correspond to three sliding blocks 31. One end of the connecting rod 32 is rotatably connected to the sliding block 31, and the other end of the connecting rod 32 is rotatably connected to the connecting block 34. A rotating handle 36 is fixedly installed on the end of the screw 33 away from the support plate 1. The rotating plate is cylindrical, and anti-slip textures are evenly distributed on the peripheral sidewall of the rotating plate. The locking nut 35 is coaxially arranged with the screw 33 and threaded to the screw 33. The locking nut 35 abuts against the end of the connecting block 34 away from the support plate 1.

[0034] Reference Figure 2 and Figure 3The three tension wheels 2 are the first tension wheel 41, the second tension wheel 42, and the third tension wheel 43. The distance between the first tension wheel 41, the second tension wheel 42, and the third tension wheel 43 and the support plate 1 increases sequentially. The yarn passes around the first tension wheel 41, the second tension wheel 42, and the third tension wheel 43 in sequence. The end of the yarn that passes around the first tension wheel 41 and the other end of the yarn that passes around the third tension wheel 43 are staggered.

[0035] Reference Figure 2 and Figure 4 A limiting plate 5 is also provided on the support plate 1. The limiting plate 5 is perpendicular to the support plate 1. A limiting hole 51 is provided on the limiting plate 5. The limiting hole 51 is perpendicular to the connecting line between the first tension wheel 41 and the third tension wheel 43. The two ends of the limiting hole 51 are rounded. The limiting hole 51 is used to introduce the warp yarn into the tension adjustment mechanism. A guide wheel 6 is also provided on the sliding block 31 corresponding to the first tension wheel 41. The guide wheel 6 is rotatably connected to the sliding block 31. The guide wheel 6 introduces the yarn from the limiting hole 51 into the first tension wheel 41. The guide wheel 6 and the first tension wheel 41 are in the same position. The yarn passes through the guide wheel 6 and winds around the first tension wheel 41 at the same angle.

[0036] The implementation principle of a tension adjustment mechanism for a warping machine according to an embodiment of this application is as follows: The operator inserts the yarn through the limiting hole 51 into the tension adjustment mechanism, passing sequentially around the driving wheel, the first tension wheel 41, the second tension wheel 42, and the third tension wheel 43. The first tension wheel 41, the second tension wheel 42, and the third tension wheel 43 are in the shape of an equilateral triangle. Due to the different distances of the first tension wheel 41, the second tension wheel 42, and the third tension wheel 43 from the support plate 1, the entry and exit ends of the yarn are staggered, reducing wear between the yarns. When the yarn tension needs to be adjusted, the operator can rotate the screw 33 through the rotating plate. The screw 33 drives the connecting block 34 to rotate, and the connecting block 34 drives the connecting rod 32 to rotate. The connecting rod 32 causes the sliding block 31 to move, changing the size of the equilateral triangle shape of the first tension wheel 41, the second tension wheel 42, and the third tension wheel 43. Thus, the tension of the yarn is adjusted without changing the wrap angle, reducing the relative slippage of the yarn relative to the tension wheel 2 and improving the quality of the yarn.

[0037] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
