Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile technology, specifically a yarn tension control device for a warping machine. Background Technology
[0002] The main purpose of yarn tension control on a warping machine is to ensure the uniformity of yarn winding. During the warping process, controlling the yarn tension is crucial. Its primary objective is to ensure that the yarn tension is uniform throughout the winding process, thereby guaranteeing the uniformity of yarn winding and preventing defects such as uneven yarn winding and streaks on the fabric surface.
[0003] During the processing, the yarn needs to be conveyed quickly and accurately. A tension controller must be installed along the yarn's path to control its tension. Existing tension controllers mainly consist of guide posts and elastic pressure blocks mounted on the guide posts, with the pressure blocks applying downward pressure to the yarn. During rapid yarn conveying, the pressure blocks' control over yarn tension is poor. Furthermore, as the radius of the subsequently wound yarn gradually increases, the downward pressure from the pressure blocks gradually tends to balance. At this point, the tension control effect of the pressure blocks becomes lagging, easily leading to problems such as yarn breakage. Summary of the Invention
[0004] The purpose of this invention is to provide a yarn tension control device for a warping machine to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A yarn tension control device for a warping machine includes: an operating table, on which a winding roller, a release roller, and a mounting frame are provided, wherein the winding roller and the release roller are connected by a chain;
[0007] The mounting frame is provided with a compensation component, which includes an elastic pressing structure. Two sets of the elastic pressing structure are symmetrically arranged along the axial direction of the winding roller. An abutting roller is provided between the two sets of the elastic pressing structure. The abutting roller can press against the yarn body wound between the winding roller and the release roller so that the tension of the yarn body remains consistent throughout the warping process.
[0008] It also includes an elastic release component installed on the operating table. The elastic release component includes a sensing structure and a triggering structure. The sensing structure can monitor the radius of the winding roller. When the radius of the winding roller reaches a preset value, the triggering structure can drive the elastic pressing structure to release so that the abutting roller can continue to compensate for the tension of the yarn body.
[0009] As described above, the warping machine yarn tension control device includes an elastic pressing structure comprising a plug-in cylinder mounted on the mounting frame. A lifting rod is inserted into one side of the plug-in cylinder facing the mounting frame, and a plug-in rod is inserted into the other side. A sleeve ring is provided at one end of the plug-in rod protruding from the plug-in cylinder. The abutting roller is rotatably mounted on two sets of sleeve rings. A first spring is also slidably mounted on the plug-in cylinder. One end of the first spring abuts against the release member, and the other end abuts against the plug-in rod.
[0010] As described above, the warping machine yarn tension control device has a lifting plate at one end of the lifting rod protruding from the insertion cylinder. The lifting plate has a fitting groove, which includes horizontal grooves equidistantly opened on the lifting plate. An inclined groove connects two adjacent sets of horizontal grooves, and a limiting groove is provided on the horizontal groove between the first and last sets of horizontal grooves.
[0011] As described above, the yarn tension control device for the warping machine has two sets of sensing structures symmetrically arranged along the axial direction of the winding roller. Each set of sensing structures includes a fixed frame mounted on the operating table. A mounting cylinder is mounted on the fixed frame, and a third spring is slidably mounted inside the mounting cylinder. One end of the third spring abuts against the fixed frame, and the other end abuts against a moving rod slidably mounted inside the mounting cylinder. An abutment plate is provided at the end of the moving rod away from the third spring, and a guide is also provided on the moving rod.
[0012] As described above, the warping machine yarn tension control device includes a guide plate fixed to the moving rod, a guide groove is provided on the guide plate, the guide groove includes vertical grooves equidistantly provided on the guide plate, and a release groove is connected between two adjacent sets of the vertical grooves.
[0013] As described above, the warping machine yarn tension control device has two sets of triggering structures symmetrically arranged along the axial direction of the winding roller. Each set of triggering structures includes a fixed cylinder arranged on the mounting frame. A second spring is slidably arranged inside the fixed cylinder. One end of the second spring abuts against the bottom of the fixed cylinder, and the other end abuts against the trigger element slidably arranged inside the fixed cylinder.
[0014] As described above, the warping machine yarn tension control device includes a telescopic rod slidably disposed within the fixed cylinder, a first sliding rod being provided at one end of the telescopic rod protruding from the fixed cylinder, the first sliding rod being slidably disposed within the guide groove, and a second sliding rod being provided on the telescopic rod.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] By setting up a compensation component, during the warping process, the elastic pressing structure can press down on the yarn wound on the release roller and the winding roller. With the cooperation of the first spring in the elastic pressing structure, the tension generated by the yarn can be dynamically compensated according to the actual tension of the yarn, so that the yarn always has uniform tension during the warping process, thereby reducing warp yarn breakage and weaving defects in subsequent processing.
[0017] Meanwhile, by setting up an elastic release component, when the radius of the subsequent winding roller increases and the compression of the first spring reaches a critical value, the elastic potential energy stored in the first spring can be released by the cooperation between the sensing structure and the triggering structure, so that the elastic pressing structure can continue to perform the tension adjustment function. With the cooperation between the components, the problems of uneven tension and lag in adjustment during the warping process can be solved. Attached Figure Description

The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.
[0028] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.
[0029] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.
[0030] Please see Figures 1-8 In this embodiment of the invention, a yarn tension control device for a warping machine includes:
[0031] The operating table 1 is equipped with a winding roller 2, a release roller 3 and a mounting frame 4. The winding roller 2 and the release roller 3 are connected by a chain 7.
[0032] Specifically, the winding roller 2 and the release roller 3 are detachably connected to the operating table 1. After the winding roller 2 and the release roller 3 are installed on the operating table 1, the yarn end of the yarn body 6 on the release roller 3 is wound onto the winding roller 2. Then the chain 7 is started, and the chain 7 drives the release roller 3 and the winding roller 2 to move synchronously, so that the yarn body 6 on the release roller 3 can be wound onto the winding roller 2, thereby completing the warping operation.
[0033] The mounting frame 4 is provided with a compensation component, which includes an elastic pressing structure. Two sets of the elastic pressing structure are symmetrically arranged along the axial direction of the winding roller 2. An abutting roller 8 is provided between the two sets of the elastic pressing structure. The abutting roller 8 can press the yarn body 6 wound between the winding roller 2 and the release roller 3 so that the tension of the yarn body 6 remains consistent during the warping process.
[0034] The elastic pressing structure includes a plug-in cylinder 10 disposed on the mounting frame 4. A lifting rod 16 is inserted into one side of the plug-in cylinder 10 facing the mounting frame 4, and a plug-in rod 18 is inserted into the other side. A sleeve ring 1801 is disposed at one end of the plug-in rod 18 protruding from the plug-in cylinder 10. The abutting roller 8 is rotatably mounted on two sets of sleeve rings 1801. A first spring 17 is also slidably disposed on the plug-in cylinder 10. One end of the first spring 17 abuts against the release member, and the other end abuts against the plug-in rod 18.
[0035] Specifically, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 The outer wall of the aforementioned lifting rod 16 is provided with a groove 1601, which is adapted to the adapter hole 401 provided on the mounting bracket 4. With the cooperation of the adapter hole 401 and the groove 1601, the lifting rod 16 can only be raised and lowered along the axial direction of the plug-in cylinder 10.
[0036] Specifically, the first spring 17 is always in a compressed and energy-storing state. In this state, the first spring 17 pushes the abutting roller 8 away from the mounting frame 4. During the warping process, the abutting roller 8 can abut against the yarn body 6 wrapped on the release roller 3 and the winding roller 2. During the pressing process, the elastic potential energy stored in the first spring 17 keeps the yarn body 6 in a taut state and keeps the tension of the yarn body 6 at an appropriate level during the warping process. In addition, during the warping process, the abutting roller 8, with the cooperation of the first spring 17, can dynamically adjust the tension of the yarn body 6 according to the actual condition of the yarn body 6, so that the yarn body 6 can maintain uniform tension during the warping process, thereby reducing the occurrence of warp yarn breakage and weaving defects in subsequent processing.
[0037] The lifting rod 16 has a lifting plate 15 at one end protruding from the plug-in cylinder 10. The lifting plate 15 has a fitting groove, which includes horizontal grooves 1501 that are equidistantly opened on the lifting plate 15. An inclined groove 1502 connects two adjacent sets of horizontal grooves 1501, and a limiting groove 1503 is provided on the horizontal groove 1501 between the first and last sets of horizontal grooves 1501.
[0038] For preferred options, please refer to [link / reference]. Figure 4 The aforementioned inclined groove 1502 is provided in two sets. During the warping process, as the winding radius of the winding roller 2 gradually increases, the squeezing force of the subsequent yarn body 6 on the abutting roller 8 will be greater, and the squeezing force of the abutting roller 8 on the first spring 17 will be greater. At this time, the contraction capacity of the first spring 17 will gradually decrease, and the ability to adjust the tension of the yarn body 6 will also be relatively reduced. At this time, by using the fitting groove in conjunction with the elastic release component installed on the operating table 1, the elastic potential energy stored in the first spring 17 can be released, so that the abutting roller 8 can continue to perform the function of adjusting the elasticity of the yarn body 6.
[0039] For details, please refer to Figures 1-8 The elastic release component includes a sensing structure and a triggering structure. The sensing structure can monitor the radius of the winding roller 2. When the radius of the winding roller 2 reaches a preset value, the triggering structure can drive the elastic pressing structure to release so that the abutting roller 8 can continue to compensate for the tension of the yarn body 6.
[0040] Two sets of sensing structures are symmetrically arranged along the axial direction of the winding roller 2. Each set of sensing structures includes a fixed frame 5 set on the operating table 1. A mounting cylinder 20 is set on the fixed frame 5. A third spring 23 is slidably arranged in the mounting cylinder 20. One end of the third spring 23 abuts against the fixed frame 5, and the other end abuts against a moving rod 21 slidably arranged in the mounting cylinder 20. An abutment plate 9 is provided at the end of the moving rod 21 away from the third spring 23, and a guide is also provided on the moving rod 21.
[0041] Specifically, the third spring 23 is in a compressed energy storage state. At this time, the compressed third spring 23 can push the abutment plate 9 close to the winding roller 2 and press it against the winding roller 2. As the radius of the winding roller 2 gradually increases, the abutment plate 9 rises along the axial direction of the mounting cylinder 20, which will further compress the third spring 23. During this process, the guide and the triggering structure cooperate to drive the lifting rod 16 to rise, thereby releasing the elastic potential energy stored in the first spring 17.
[0042] The guide includes a guide plate 22 fixed to the moving rod 21. The guide plate 22 has a guide groove. The guide groove includes vertical grooves 2201 that are equidistantly opened on the guide plate 22, and a release groove 2202 is connected between two adjacent sets of vertical grooves 2201.
[0043] For preferred options, please refer to [link / reference]. Figure 2 , Figure 7 , Figure 8The guide plate 22 slides in the moving groove 2001 opened on the side wall of the mounting cylinder 20. With the cooperation of the moving groove 2001 and the guide plate 22, the guide plate 22 can only move up and down along the axial direction of the mounting cylinder 20. The vertical groove 2201 is provided in three sets.
[0044] Furthermore, the triggering structure is symmetrically arranged in two sets along the axial direction of the winding roller 2. Each set of the triggering structure includes a fixed cylinder 11 disposed on the mounting frame 4. A second spring 19 is slidably disposed inside the fixed cylinder 11. One end of the second spring 19 abuts against the bottom of the fixed cylinder 11, and the other end abuts against the triggering element slidably disposed inside the fixed cylinder 11.
[0045] The trigger includes a telescopic rod 13 slidably disposed within the fixed cylinder 11. One end of the telescopic rod 13 protruding from the fixed cylinder 11 is provided with a first slide rod 12. The first slide rod 12 is slidably disposed within the guide groove. A second slide rod 14 is also provided on the telescopic rod 13.
[0046] Specifically, the second spring 19 is in a compressed energy storage state, and in its initial state (refer to...) Figure 2 The second slide bar 14 is located at the beginning of the stroke of the upper horizontal groove 1501, and the first slide bar 12 is located at the beginning of the stroke of the upper vertical groove 2201.
[0047] In combination with the above, during the warping process, as the radius of the winding roller 2 increases, the abutting roller 8 gradually rises due to the tension of the yarn body 6. At the same time, the winding roller 2 can force the abutting plate 9 to drive the guide plate 22 to rise. During this process, the first slide rod 12 slides along the uppermost vertical groove 2201 until the abutting roller 8 forces the first spring 17 to reach the critical energy storage state. Then, the first slide rod 12 engages with the uppermost release groove 2202. Subsequently, the second spring 19 releases its elastic potential energy, pushing the telescopic rod 13 to drive the first slide rod 12 to slide along the release groove 2202 until the first slide rod 12 engages with the next set of vertical grooves 2201. The vertical groove 2201 can lock the position of the first slide rod 12 and the telescopic rod 13 so that the telescopic rod 13 and the first slide rod 12 stop moving.
[0048] Furthermore, during the movement of the telescopic rod 13, the second slide rod 14 can first slide along the uppermost horizontal groove 1501 until the second slide rod 14 engages with the inclined groove 1502. With the movement of the telescopic rod 13, the contact compression of the second slide rod 14 against the inclined groove 1502 can force the lifting plate 15 to drive the lifting rod 16 to rise, thereby releasing the elastic potential energy stored in the first spring 17. Until the second slide rod 14 separates from the inclined groove 1502, the second slide rod 14 engages with the next set of horizontal grooves 1501. At this time, the force generated by the first spring 17 on the lifting rod 16 can push the lifting rod 16 and the lifting plate 15 to have an upward tendency, so that the second slide rod 14 engages with the limiting groove 1503, thereby locking the position of the lifting plate 15 and the lifting rod 16 so that the abutment roller 8 can continue to perform the tension adjustment function.
[0049] When the energy stored in the first spring 17 reaches the critical point again, the above process is repeated to release the elastic potential energy stored in the first spring 17 again until the first slide bar 12 moves to the end of the stroke of the lowest vertical groove 2201. At this point, the warping device stops working, the winding roller 2 finishes winding, and after the winding roller 2 is removed, the third spring 23 releases its elastic potential energy (the elastic potential energy stored in the third spring 23 is greater than the elastic potential energy stored in the second spring 19), which can drive each component back to its initial position so that the warping operation of the yarn body 6 can be performed next time.
[0050] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
