Description

Technical Field

[0001] This utility model relates to the field of fabric processing technology, specifically to a yarn tension frame for a braiding machine used in the production of woven fabrics. Background Technology

[0002] In the production of woven fabrics, the precise control of yarn tension directly determines the quality and performance of the finished product. Whether used in packaging, geotechnical construction, or high-end composite materials, the density uniformity and surface smoothness of woven fabrics depend on the yarn maintaining a stable and appropriate tension during the weaving process.

[0003] However, traditional tension frames mostly use fixed structures or simple spring adjustment devices, which are difficult to respond to the dynamic changes in yarn tension during the weaving process in real time. When the weaving machine starts or the speed changes, the tension force on the yarn fluctuates greatly. These tension frames cannot automatically adjust according to the actual tension, which can easily lead to the weaving yarn getting tangled and knotted due to insufficient tension, or breaking and wearing due to excessive tension. This seriously affects the continuity of weaving and the yield of finished fabric. In addition, some tension frame adjustment processes rely on manual operation, which is not only inefficient, but also difficult to adapt to complex and changing weaving conditions and cannot meet the production requirements of high-precision woven fabrics. Therefore, there is an urgent need for a yarn tension frame for weaving machines that produces woven fabrics to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a yarn tension frame for a braiding machine used in the production of woven fabrics, in order to solve the problem mentioned in the background art that traditional braiding machine tension frames are difficult to adaptively adjust according to the tension of the braiding yarn.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a yarn tension frame for a braiding machine used in the production of woven fabric, comprising a tension frame body, wherein an adaptive tensioning component is provided at the lower end of the tension frame body;

[0006] The adaptive tensioning assembly includes a fixed plate, which is fixedly connected to the lower end of the tension frame body. Multiple fixed frames are fixedly connected to the lower end of the fixed plate. A connecting frame is fixedly connected to the inner wall of the fixed frame. A rotating roller is rotatably connected to the inner wall of the connecting frame. A support column is rotatably connected to the inner wall of the fixed frame. A sliding frame is slidably connected to the surface of the support column. An adjusting roller is rotatably connected to the inner wall of the sliding frame. A compression spring is sleeved on the surface of the support column.

[0007] Preferably, the inner wall of the fixed disk is rotatably connected to a threaded column, the surface of the threaded column is threadedly connected to a threaded adjusting block, the inner wall of the threaded adjusting block is slidably connected to the surface of the support column, and the upper end of the compression spring abuts against the bottom surface of the threaded adjusting block.

[0008] Preferably, the connecting frame has limit holes on both sides, and two limit blocks are slidably connected to the inner wall of the limit holes. The two limit blocks are respectively fixedly connected to the top and bottom surfaces of the sliding frame.

[0009] Preferably, the bottom surface of the fixing frame has two positioning holes, and the inner wall of the positioning holes is fixedly connected to a positioning post, and the multiple positioning posts are fixedly connected to the lower end of the tension frame body.

[0010] Preferably, a support block is fixedly connected to the side wall of the fixing frame, and the side wall of the support block is fixedly connected to the side wall of the connecting frame.

[0011] Preferably, the surface of the threaded column is rotatably connected to the inner wall of the support block, and the surface of the support column is rotatably connected to the inner wall of the support block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The adaptive tensioning component allows the compression spring to contract based on the tension applied to the braiding thread when the braiding machine starts. This causes the adjusting roller to move adaptively along the inner wall of the connecting frame, maintaining a uniform and appropriate tension on the braiding thread and improving the stability of the woven fabric produced by the braiding machine. Simultaneously, the threaded column and threaded adjusting block work together, allowing rotation of the threaded column to compress the compression spring. This compensates for the reduced elasticity of the compression spring due to fatigue during long-term use, ensuring its sustained performance and lifespan. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0019] Please see Figures 1-3 This utility model provides a yarn tension frame for a braiding machine used in the production of woven fabrics. It includes a tension frame body 1, with an adaptive tensioning component 2 at the lower end of the tension frame body 1. The adaptive tensioning component 2 includes a fixed plate 201, which is fixedly connected to the lower end of the tension frame body 1. Multiple fixed frames 202 are fixedly connected to the lower end of the fixed plate 201. A connecting frame 203 is fixedly connected to the inner wall of each fixed frame 202. A rotating roller 204 is rotatably connected to the inner wall of each connecting frame 203. A support column 205 is rotatably connected to the inner wall of each fixed frame 202. A sliding frame 206 is slidably connected to the surface of the support column 205. An adjusting roller 207 is rotatably connected to the inner wall of the sliding frame 206, and a compression spring 208 is sleeved on the surface of the support column 205. Through the adaptive pulling component 2, the braiding thread passes between the rotating roller 204 and the adjusting roller 207. When the braiding machine is started, the braiding thread is pulled, and the compression spring 208 is driven to contract according to the magnitude of the tension on the braiding thread. This causes the adjusting roller 207 to move adaptively on the inner wall of the connecting frame 203, thereby maintaining a uniform and appropriate tension on the braiding thread. This avoids insufficient tension causing tangling or excessive tension causing damage to the braiding thread, and improves the stability of the braiding machine in producing woven fabric.

[0020] Furthermore, a threaded post 209 is rotatably connected to the inner wall of the fixed disk 201, and a threaded adjusting block 210 is threadedly connected to the surface of the threaded post 209. The inner wall of the threaded adjusting block 210 is slidably connected to the surface of the support post 205. The upper end of the compression spring 208 abuts against the bottom surface of the threaded adjusting block 210. Through the cooperation of the threaded post 209 and the threaded adjusting block 210, rotating the threaded post 209 can drive the threaded adjusting block 210 to move. The movement of the threaded adjusting block 210 can compress the compression spring 208, thereby facilitating the compensation of the reduced elasticity of the compression spring 208 due to fatigue during long-term use, so that the compression spring 208 can maintain its long-term performance and service life.

[0021] Furthermore, limit holes 211 are provided on both sides of the connecting frame 203. Two limit blocks 212 are slidably connected to the inner wall of the limit hole 211. The two limit blocks 212 are fixedly connected to the top and bottom surfaces of the sliding frame 206, respectively. The limit holes 211 and the limit blocks 212 cooperate with each other to facilitate the limiting of the sliding frame 206, so that the sliding frame 206 can move up and down in parallel.

[0022] Furthermore, the bottom surface of the fixing frame 202 has two positioning holes 214, and the inner wall of the positioning holes 214 is fixedly connected to positioning posts 215. Multiple positioning posts 215 are fixedly connected to the lower end of the tension frame body 1. The positioning holes 214 and positioning posts 215 cooperate with each other to facilitate the positioning of the fixing frame 202, thereby improving the accuracy of the installation of the fixing frame 202.

[0023] Furthermore, a support block 213 is fixedly connected to the side wall of the fixed frame 202. The side wall of the support block 213 is fixedly connected to the side wall of the connecting frame 203. The support block 213 facilitates the reconnection between the fixed frame 202 and the connecting frame 203, thereby improving the stability of the connecting frame 203 in use.

[0024] Furthermore, the surface of the threaded column 209 is rotatably connected to the inner wall of the support block 213, and the surface of the support column 205 is rotatably connected to the inner wall of the support block 213. The support block 213 facilitates the support of the threaded column 209 and the support column 205, thereby improving the stability of the threaded column 209 and the support column 205 in use.

[0025] Working principle: During use, the adaptive tensioning component 2 allows the braided thread to pass between the rotating roller 204 and the adjusting roller 207. When the braiding machine starts and the braided thread is pulled, the compression spring 208 contracts according to the magnitude of the tension on the braided thread. This causes the adjusting roller 207 to move adaptively on the inner wall of the connecting frame 203, thereby maintaining a uniform and appropriate tension on the braided thread. This prevents the braided thread from tangling due to insufficient tension or from being damaged due to excessive tension, thus improving the stability of the woven fabric produced by the braiding machine.

[0026] Meanwhile, the threaded column 209 and the threaded adjusting block 210 work together so that rotating the threaded column 209 can drive the threaded adjusting block 210 to move. The movement of the threaded adjusting block 210 can compress the compression spring 208, thereby compensating for the reduced elasticity of the compression spring 208 due to fatigue during long-term use, and ensuring that the compression spring 208 maintains its long-term performance and service life.
