Description

Technical Field

[0001] This invention relates to the field of textile equipment technology, and more specifically to a tension regulating device for fabric winding. Background Technology

[0002] In textile, dyeing and finishing processes, winding is a key step in ensuring fabric quality.

[0003] Most existing winding equipment is equipped with guide components. While these components guide the fabric being wound, they are typically fixed directly to the frame, only suitable for fabrics of specific weights and materials. When changing to other types of fabric, the required winding tension varies significantly due to differences in thickness, elasticity, and non-elasticity. The fixed guide path cannot provide the necessary friction conditions. Operators often need to manually disassemble and re-fix the guide rollers to accommodate different fabric types, a process that is time-consuming, labor-intensive, and cumbersome.

[0004] To address this, we propose a tension adjustment device for fabric winding. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a tension adjustment device for fabric winding.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a tension adjusting device for fabric winding, comprising a base and fabric disposed above the base; a winding mechanism, comprising a winding shaft fixed to one end of the fabric and disposed above one end of the base for winding the fabric, and support plates disposed at both ends of the winding shaft and fixed to the top side of the base for supporting the winding shaft; and a guiding mechanism, comprising a guide roller and a movable roller disposed sequentially from top to bottom above the other end of the base and in contact with the fabric for guiding the fabric. Support plates are fixed to the top side of the base at both ends of the guide roller for supporting the guide roller. An installation shaft is fixedly inserted through the middle of the movable roller. Movable plates are rotatably connected to both ends of the installation shaft, sliding between the two support plates and in contact with adjacent support plates. Through the operation of the above components, the fabric can be wound up, a certain tension can be provided to the wound fabric, and the tension can be adjusted according to the type of fabric.

[0007] Furthermore, a push plate that slides on the top side of the base is provided on one side of the movable roller. One end of the movable plate is fixed to the push plate, and a screw for driving the push plate to move is threaded through the middle of the push plate. One end of the screw is rotatably connected to a support block fixed on the top side of the base for supporting the screw, and the other end of the screw is fixed to a handle for turning the screw. Turning the handle drives the screw to rotate. Through the threaded engagement between the screw and the push plate, the push plate and the movable plate are moved, which in turn drives the mounting shaft and the movable roller to move. At this time, the position of the movable roller can be adjusted.

[0008] Furthermore, a guide groove is provided on the side of the movable plate away from the mounting axis, and a guide block fixed on the adjacent support plate is slidably connected inside the guide groove. Through the sliding cooperation of the guide groove and the guide block, the movable plate can be guided to move.

[0009] Furthermore, a connecting shaft rotatably connected between two support plates is fixedly inserted through the middle of the guide roller. A lead screw with opposite thread directions at both ends is provided on one side of the guide roller. A limiting ring that slides outside the guide roller is threaded onto the outer wall of both ends of the lead screw. A loading block is fixed between the two support plates above the guide roller. A loading groove is opened at the bottom end of the loading block. A scraper with its bottom end abutting against the fabric and used to scrape off debris from the outside of the fabric is slidably inserted inside the loading groove. A conductive rod with its tail end extending through to the top of the loading block is fixed at the top side of both ends of the scraper. A spring is movably sleeved on the outside of the conductive rod located inside the loading groove. One end of the spring is fixed to the top of the scraper, and the other end of the spring is fixed to the inner wall at the top of the loading groove. Through the operation of the above components, the lateral swing of the fabric can be restricted, debris on the outside of the fabric can be scraped off, and the scraper can be made to lightly press the fabric surface.

[0010] Furthermore, the limiting ring has a slot, and the loading block and scraper are slidably inserted inside the slot. The slot prevents the loading block and scraper from interfering with the displacement of the limiting ring.

[0011] Furthermore, one end of the take-up shaft is rotatably connected to a support plate located at one end of the take-up shaft, and the other end of the take-up shaft is connected to a motor. The motor is fixed to the support plate located at the other end of the take-up shaft, and the motor can drive the take-up shaft to rotate.

[0012] Furthermore, the top of the conductive rod is fixed with a wire whose tail end is fixed to the grounding terminal of the workshop for transmitting static electricity. Both the scraper and the conductive rod are made of conductive materials. Through the scraper that abuts against the fabric, and through the conductive rod and wire connected to the scraper, static electricity on the fabric can be conducted to the grounding terminal.

[0013] Furthermore, a rotating sleeve for rotating the lead screw is fixedly sleeved on the outer wall of the middle part of the lead screw. By rotating the rotating sleeve, the lead screw can be rotated.

[0014] Furthermore, both sides of the second support plate are fixed with mounting plates, and the two ends of the lead screw are rotatably connected to the adjacent mounting plates. The other side of the guide roller is provided with a guide rod with both ends fixed to the adjacent mounting plates. The limiting ring is provided with a guide hole, and the guide rod slides through the guide hole. Through the cooperation of the guide rod and the guide hole, the displacement limiting ring can be guided, thereby improving the stability of the limiting ring.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention can perform fabric winding. By adjusting the distance between the movable roller and the guide roller, the wrap angle of the fabric between the two rollers can be changed. When the wrap angle is larger, the frictional resistance between the fabric and the roller surface is greater, and the winding tension is greater. When the wrap angle is smaller, the tension is smaller, thus adapting to fabrics of different materials. No disassembly and reassembly are required, saving time and effort. The invention can restrict the winding of the fabric to prevent the fabric from shifting laterally during the winding process, ensuring neat fabric edges. Furthermore, the position of the restricting component can be flexibly adjusted according to different widths of fabric, making it widely applicable.

[0016] 2. This invention can remove impurities from the surface of fabric, improving the cleanliness of the fabric. At the same time, through the use of a conductive scraper, and the cooperation of the conductive rod and wire, the static electricity generated by the friction of the fabric can be conducted to the grounding end, avoiding the accumulation of static electricity that may cause sparks or attract dust. It has high working performance and can also make the scraper always lightly press on the surface of the fabric, improving the scraper's endurance. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: Combination Figure 1 , Figure 2 and Figure 3 The fabric winding tension adjustment device of this embodiment includes a base 1 and a fabric 3 disposed above the base 1. The winding mechanism includes a winding shaft 2 fixed to one end of the fabric 3 and disposed above one end of the base 1 for winding the fabric 3, and support plates 23 disposed at both ends of the winding shaft 2 and fixed to the top side of the base 1 for supporting the winding shaft 2. The guiding mechanism includes a guide roller 4 and a movable roller 5 disposed sequentially from top to bottom above the other end of the base 1 and abutting against the fabric 3 for guiding the fabric 3. The guide roller 4 and the movable roller 5 are staggered. The two ends of the guide roller 4 are provided with support plates 12 fixed to the top side of the base 1 for supporting the guide roller 4. The middle of the movable roller 5 is fixedly provided with an installation shaft 6. The two ends of the installation shaft 6 are rotatably connected to movable plates 7 that slide between the two support plates 12 and abut against the adjacent support plates 12.

[0021] The implementation principle of the tension adjustment device for fabric winding in this embodiment is as follows: When the fabric needs to be wound, one end of the fabric 3 is wrapped around the lower part of the movable roller 5 and the upper part of the guide roller 4, and finally fixed around the outside of the winding shaft 2. Then the winding shaft 2 rotates, and the fabric 3 on the outside of the winding shaft 2 is wound up. Through the movable roller 5 and the guide roller 4, the fabric 3 can be provided with a certain tension while providing a guiding direction, so as to avoid wrinkles in the fabric 3 during the winding process, ensuring that the fabric 3 is flat and improving product quality. When it is necessary to adjust the tension according to the type of fabric 3, the displacement of the movable plate 7 drives the installation shaft 6 and the movable roller 5 to move. At this time, the distance between the movable roller 5 and the guide roller 4 can be adjusted, thereby adjusting the wrap angle between the fabric 3 and the movable roller 5, and adjusting the wrap angle between the fabric 3 and the guide roller 4, thereby adjusting the frictional resistance between the fabric 3 and the movable roller 5 and the guide roller 4, and thus adjusting the tension.

[0022] Example 2: Combination Figure 4 and Figure 5 This embodiment is further improved on the basis of embodiment 1 as follows: A push plate 8 is provided on one side of the movable roller 5 and slides on the top side of the base 1. One end of the movable plate 7 is fixed on the push plate 8. A screw 9 for driving the push plate 8 to move is threaded through the middle of the push plate 8. The screw 9 is a self-locking screw. One end of the screw 9 is rotatably connected to a support block 10 fixed on the top side of the base 1 for supporting the screw 9. The other end of the screw 9 is fixed with a handle for turning the screw 9. Turning the handle drives the screw 9 to rotate. Through the threaded engagement between the screw 9 and the push plate 8, the push plate 8 and the movable plate 7 are moved, which in turn drives the mounting shaft 6 and the movable roller 5 to move. At this time, the position of the movable roller 5 can be adjusted.

[0023] A guide groove 13 is provided on the side of the movable plate 7 away from the mounting shaft 6. A guide block 14 fixed on the adjacent support plate 12 is slidably connected inside the guide groove 13. The movable plate 7 can be guided by the sliding cooperation between the guide groove 13 and the guide block 14.

[0024] Example 3: Combination Figure 6This embodiment, based on embodiment 1, further improves upon the following: a connecting shaft 11, rotatably connected between two support plates 12, is fixedly inserted through the middle of the guide roller 4; a lead screw 20 with opposite thread directions at both ends is provided on one side of the guide roller 4; the lead screw 20 is a self-locking lead screw; a limiting ring 21, sliding outside the guide roller 4, is threaded onto the outer wall of both ends of the lead screw 20; a loading block 15, fixed between the two support plates 12, is provided above the guide roller 4; a loading groove 16 is provided at the bottom of the loading block 15; a scraper 17, whose bottom end abuts against the fabric 3 and is used to scrape away debris from the outside of the fabric 3, is slidably inserted inside the loading groove 16; a conductive rod 18, whose tail end extends through to the top of the loading block 15, is fixed to the top side of both ends of the scraper 17; and a movably sleeved outer part of the conductive rod 18 located inside the loading groove 16 is provided with... Spring 19, one end of which is fixed to the top of scraper 17, and the other end of which is fixed to the inner wall of the top of loading groove 16. When the take-up shaft 2 takes up the fabric, the distance between the two limiting rings 21 can be adjusted according to the width of the fabric. Rotating the screw 20, the limiting rings 21 are moved by the threaded engagement between the screw 20 and the limiting rings 21. After the position of the limiting rings 21 is adjusted, one end of the fabric 3 is wrapped around the bottom of the movable roller 5 and the top of the guide roller 4, and finally fixed around the outside of the take-up shaft 2. Then the take-up shaft 2 rotates, and the fabric 3 on the outside of the take-up shaft 2 is taken up by the rotation of the take-up shaft 2. When the take-up shaft 2 takes up the fabric 3, the limiting rings 21 on both sides of the fabric 3 can limit the lateral swing of the fabric and improve the stability of the fabric.

[0025] When the fabric 3 moves on the surface of the guide roller 4, the scraper 17 can scrape away the debris on the outside of the fabric 3. When the scraper 17 wears out after a long period of scraping, the operation of the spring 19 drives the scraper 17 to lightly press the fabric surface, thereby improving the endurance of the scraper 17.

[0026] The limiting ring 21 has a slot, and the loading block 15 and scraper 17 are slidably inserted inside the slot. The slot can prevent the loading block 15 and scraper 17 from interfering with the displacement of the limiting ring 21.

[0027] One end of the take-up shaft 2 is rotatably connected to a support plate 23 located at one end of the take-up shaft 2, and the other end of the take-up shaft 2 is connected to a motor. The motor is a forward and reverse stepper motor, which is fixed on the support plate 23 located at the other end of the take-up shaft 2. The motor can drive the take-up shaft 2 to rotate.

[0028] The top end of the conductive rod 18 is fixed with a wire that is fixed to the grounding terminal of the work workshop for transmitting static electricity. Both the scraper 17 and the conductive rod 18 are made of conductive material. Through the scraper 17 that abuts against the fabric 3, and through the conductive rod 18 and the wire connected to the scraper 17, the static electricity on the fabric 3 can be conducted to the grounding terminal.

[0029] A rotating sleeve 22 is fixedly sleeved on the outer wall of the middle part of the lead screw 20. By rotating the rotating sleeve 22, the lead screw 20 can be rotated.

[0030] Both sides of the support plate 212 are fixed with a fixed plate 24. The two ends of the lead screw 20 are rotatably connected to the adjacent fixed plate 24. The other side of the guide roller 4 is provided with a guide rod 25 with both ends fixed to the adjacent fixed plate 24. The limiting ring 21 has a guide hole. The guide rod 25 slides through the guide hole. Through the cooperation of the guide rod 25 and the guide hole, the displacement limiting ring 21 can be guided, thereby improving the stability of the limiting ring 21.

[0031] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
