Description

Technical Field

[0001] This utility model relates to the field of textile yarn technology, and in particular to a textile yarn tension adjustment device. Background Technology

[0002] Textile yarn is a continuous linear material made from textile fibers through twisting, wrapping, and aggregation. It is the basic raw material for the production of textiles such as weaving, knitting, and embroidery. A textile yarn tension regulating device is an electromechanical device used to control and stabilize the tension of yarn during the textile processing. Its core function is to ensure that the yarn maintains a constant tension during conveying, traction, or winding, avoiding negative impacts on product quality and production efficiency due to excessive or insufficient tension.

[0003] To address this, patent CN219525887U discloses a yarn tension adjusting device for textile processing, comprising a base, with support frames fixedly connected to the front and rear ends of the top center of the base, a mounting frame fixedly connected between the top of the support frames, an electric telescopic rod and a connecting sleeve fixedly connected to the front and rear ends of the bottom of the mounting frame, a lifting rod penetrating and slidably connected between the support frames, a tension detector and a guide wheel penetrating and disposed in the middle of the lifting rod, screw cylinders fixedly connected to both the front and rear sides of the lifting rod, a screw rod threadedly connected to the bottom end of each screw cylinder, a single-layer rotating drum fixedly connected to the bottom of each screw rod, a motor penetrating and fixedly connected to the center of the bottom of the base, and a double-layer rotating drum fixedly connected to the output end of the motor. This invention can simultaneously detect yarn tension and provide emergency stop, effectively preventing breakage due to over-adjustment.

[0004] The yarn tension regulating device for textile processing described above changes the yarn tension by adjusting the height of the lifting rod through an electric telescopic rod during use. It can only achieve single-dimensional adjustment in the vertical direction and cannot adjust the horizontal unwinding speed or the vertical height, making it difficult to meet the dynamic tension balance requirements under complex yarn paths. Utility Model Content

[0005] The purpose of this invention is to provide a yarn tension regulating device to solve the problem that existing yarn tension regulating devices for textile processing are not convenient for multi-directional adjustment.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a textile yarn tension adjustment device, including a base plate;

[0007] An adjustment structure is fixed on both sides of the top of the base plate. The adjustment structure includes a first bracket fixed to one side of the top of the base plate. A sliding groove is provided on both sides of the first bracket. A slider is installed inside the sliding groove. A first motor is fixed on one side of the slider. A connecting shaft is installed on the other side of the slider. A take-up roller is installed on the outside of the connecting shaft. A support plate is fixed at the top of the first bracket. A connecting plate is fixed at the bottom of the slider. A lifting plate is fixed at the top of the connecting plate. A first screw is installed at the middle position of the top of the support plate. Guide rods are fixed on both sides of the top of the support plate.

[0008] A wire structure is fixed at the middle position of the top of the base plate.

[0009] Preferably, a movable groove is provided on the other side of the top of the base plate, a second screw is installed inside the movable groove, a moving block is installed on the outside of the second screw, a second motor is fixed to one end of the second screw on one side of the base plate, guide grooves are provided at the top of the base plates on both sides of the movable groove, guide blocks are installed inside the guide grooves, a second bracket is fixed to the top of the moving block and the guide block, and a feeding roller is installed inside the second bracket.

[0010] Preferably, the grooves are symmetrically distributed on both sides of the first bracket, the slider and the first bracket are slidably connected through the grooves, one end of the connecting shaft is fixedly connected to the output end of the first motor, and a tension detector is installed inside the take-up roller.

[0011] With the above structure, the sliding grooves are symmetrically distributed on both sides of the first support during use, so that the slider is subjected to uniform force during sliding, and it is not easy to deviate or jam. This ensures the stability and symmetry of the take-up roller when adjusting the height. In addition, the tension detector installed inside the take-up roller can monitor the tension of the yarn in real time during the winding process and feed the tension data back to the control system. This provides a basis for subsequent adjustment of the yarn tension, so as to adjust the relevant structure in a timely manner and keep the yarn tension within a suitable range.

[0012] Preferably, the connecting plate is arranged in an "L" shape, the bottom end of the first screw and the top end of the support plate are rotatably connected by a bearing, the guide rods are symmetrically distributed on both sides of the top end of the support plate, the lifting plate is threadedly connected to the first screw, and the lifting plate is slidably connected to the guide rods.

[0013] With the above structure, the guide rods symmetrically distributed on both sides can accurately guide the lifting movement of the lifting plate during use, restricting the lifting plate to move only along the axial direction of the guide rods, and preventing it from shaking or deviating during the lifting process.

[0014] Preferably, the movable block is threadedly connected to the second screw, the guide grooves are symmetrically distributed on both sides of the movable groove at the top of the base plate, the guide block and the base plate are slidably connected through the guide grooves, and the two ends of the feeding roller are rotatably connected to both sides inside the second bracket.

[0015] With the above structure, the guide groove and guide block form a sliding connection during use, which can play a dual guiding and limiting role in the movement of the second support, preventing the pay-off roller from deviating or shaking when moving horizontally, ensuring the stability of the yarn pay-off path, and preventing uneven yarn tension caused by movement deviation.

[0016] Preferably, the conductor structure includes a third bracket fixed at the middle position of the top of the base plate. A reciprocating lead screw is installed inside the third bracket. A third motor is fixed to one end of the reciprocating lead screw on one side of the third bracket. A threaded sleeve is installed on the outside of the reciprocating lead screw. Connecting discs are fixed to both ends of the threaded sleeve. A conductor wheel is fixed between the connecting discs on the outside of the threaded sleeve. A limit rod is fixed to the outside of the reciprocating lead screw inside the third bracket. A sliding hole is provided inside the connecting disc on the outside of the limit rod.

[0017] Preferably, the reciprocating lead screw and the threaded sleeve are threadedly connected, the guide wheel is arranged in a ring, the limiting rods are evenly distributed inside the connecting plate, and the connecting plate and the limiting rods are slidably connected through sliding holes.

[0018] With the above structure, the connecting plate is slidably connected to the limiting rod through the sliding hole during use, which can precisely limit the movement trajectory of the connecting plate and the guide wheel, so that it can only move along the axial direction of the limiting rod, ensuring the stability and straightness of the guide wheel's movement, and thus ensuring the effect of uniform yarn winding.

[0019] The advantages of the textile yarn tension adjusting device provided by this utility model are as follows:

[0020] Equipped with an adjustment structure and a built-in tension detector on the take-up roller, the yarn tension can be monitored in real time. When the tension is abnormal, the control system drives the second motor to rotate the second screw, and adjusts the horizontal position of the pay-off roller via a moving block to prevent the yarn from breaking due to excessive tension or becoming too loose due to insufficient tension. Furthermore, rotating the first screw allows the lifting plate to slide up and down along the guide rod, and the connecting plate drives the slider to move within the groove, thereby flexibly adjusting the height of the take-up roller to adapt to the pulling angle requirements of different yarn paths. This is suitable for yarn path switching in multi-process textile equipment.

[0021] By incorporating a guide wire structure, a third motor drives a reciprocating lead screw to rotate, causing the threaded sleeve and guide wire wheel to reciprocate along a limiting rod. This guides the yarn to be evenly distributed, preventing accumulation or overlap. Furthermore, the limiting rod, in conjunction with a sliding hole, restricts the movement trajectory of the connecting disc, ensuring the accuracy of the guide wire wheel's movement. Even during high-speed winding, the yarn remains evenly arranged, reducing wear and breakage. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-5 The textile yarn tension adjustment device provided by this utility model includes a base plate 1.

[0030] Reference Figures 1-4As shown, adjustment structures 2 are fixed on both sides of the top of the base plate 1. Each adjustment structure 2 includes a first bracket 201 fixed to one side of the top of the base plate 1. Slide grooves 202 are provided on both sides of the first bracket 201. A slider 203 is installed inside the slide grooves 202. A first motor 204 is fixed to one side of the slider 203, and a connecting shaft 205 is installed on the other side of the slider 203. A take-up roller 206 is installed on the outside of the connecting shaft 205. A support plate 207 is fixed to the top of the first bracket 201, and a connecting plate 208 is fixed to the bottom of the slider 203. A lifting plate 209 is fixed to the top of plate 208. A first screw 210 is installed at the middle position of the top of support plate 207. Guide rods 211 are fixed on both sides of the top of support plate 207. A movable groove 212 is provided on the other side of the top of base plate 1. A second screw 213 is installed inside the movable groove 212. A moving block 214 is installed on the outside of the second screw 213. A second motor 215 is fixed to one end of the second screw 213 on one side of base plate 1. Guide grooves 216 are provided on the top of base plate 1 on both sides of the movable groove 212. The inner part of the guide groove 216... The first support 201 is equipped with a guide block 217, and a second bracket 218 is fixed to the top of the moving block 214 and the guide block 217. A feed roller 219 is installed inside the second bracket 218. Slide grooves 202 are symmetrically distributed on both sides of the first support 201. A slider 203 is slidably connected to the first support 201 via the slide grooves 202. One end of the connecting shaft 205 is fixedly connected to the output end of the first motor 204. A tension detector is installed inside the take-up roller 206. The connecting plate 208 is L-shaped. The bottom end of the first screw 210 is connected to the support plate 219. The top of 07 is rotatably connected by a bearing. The guide rod 211 is symmetrically distributed on both sides of the top of the support plate 207. The lifting plate 209 is threadedly connected to the first screw 210. The lifting plate 209 is slidably connected to the guide rod 211. The moving block 214 is threadedly connected to the second screw 213. The guide groove 216 is symmetrically distributed on both sides of the movable groove 212 at the top of the base plate 1. The guide block 217 is slidably connected to the base plate 1 through the guide groove 216. The two ends of the wire feeding roller 219 are rotatably connected to both sides inside the second bracket 218.

[0031] The tension of the yarn is monitored in real time by a tension detector inside the take-up roller 206. When the tension is too high or too low, the tension detector transmits a signal to the control system, which then drives the second motor 215 to rotate the second screw 213. This rotates the screw 214, causing the pay-off roller 219 to move horizontally, adjusting the pay-off speed of the yarn and achieving tension balance with the take-up roller 206. At the same time, the movement of the second bracket 218 causes the guide block 217 to slide in the guide groove 216, ensuring the stability of the pay-off roller 219 during movement and preventing yarn deviation. Furthermore, rotating the first screw 210 drives the lifting plate 209 to slide up and down along the guide rod 211, which in turn drives the connecting plate 208 to make the slider 203 slide on both sides of the first bracket 201 through the groove 202, thereby adjusting the height of the take-up roller 206 and the yarn pulling angle to adapt to the tension requirements of different yarn paths.

[0032] Reference Figure 1 , Figure 2 and Figure 5 As shown, a wire structure 3 is fixed at the middle position of the top of the base plate 1. The wire structure 3 includes a third bracket 301 fixed at the middle position of the top of the base plate 1. A reciprocating screw 302 is installed inside the third bracket 301. A third motor 303 is fixed at one end of the reciprocating screw 302 on one side of the third bracket 301. A threaded sleeve 304 is installed on the outside of the reciprocating screw 302. A connecting plate 305 is fixed at both ends of the threaded sleeve 304. A guide wheel 306 is fixed between the connecting plates 305 on the outside of the threaded sleeve 304. A limit rod 307 is fixed on the outside of the reciprocating screw 302 inside the third bracket 301. A sliding hole 308 is provided inside the connecting plate 305 on the outside of the limit rod 307. The reciprocating screw 302 and the threaded sleeve 304 are threadedly connected. The guide wheel 306 is arranged in a ring. The limit rods 307 are evenly distributed inside the connecting plate 305. The connecting plate 305 and the limit rods 307 are slidably connected through the sliding hole 308.

[0033] By starting the third motor 303 to drive the reciprocating screw 302 to rotate, the threaded sleeve 304 moves axially along the reciprocating screw 302, thereby causing the connecting plate 305 to move outside the limiting rod 307 through the sliding hole 308. The limiting rod 307 restricts the movement trajectory of the connecting plate 305, ensuring that the guide wheel 306 moves in a straight line, thus guiding the yarn to be evenly distributed during the winding process and avoiding accumulation or overlap.
