Description

Technical Field

[0001] This utility model relates to the field of warp knitting machine technology, and in particular to a warp knitting machine tensioning device with adjustable spacing between multiple tension rollers. Background Technology

[0002] Warp knitting is a technique that uses one or more groups of parallel yarns to simultaneously form loops on all the working needles of a machine in the warp direction, creating a knitted fabric. The resulting fabric is called warp-knitted fabric, and the machine that performs this type of warp knitting is called a warp knitting machine. A warp knitting machine mainly consists of a knitting mechanism, a guide bar traversing mechanism, a warp feed mechanism, and a tensioning device. The tensioning device is one of the main components of the warp knitting machine; its function is to pull the fabric woven by the knitting mechanism out of the knitting area and wind it into a roll.

[0003] During prolonged use, existing warp knitting machines may experience wear and tear on internal components such as bearings and connectors, leading to the detachment of the tension rollers. After the tension rollers detach, the fabric may accumulate or wrinkle in the knitting area, and may even rub or collide with other components, resulting in scratches, abrasions, and other defects on the fabric surface, which adversely affects the quality of the warp-knitted products. Utility Model Content

[0004] This utility model discloses a warp knitting machine tensioning device with adjustable spacing between multiple tension rollers, aiming to solve the technical problem that existing devices become loose due to wear during long-term use, leading to the detachment of tension rollers and adversely affecting the quality of warp knitting products.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multi-traction roller spacing adjustable warp knitting machine traction device includes a warp knitting machine body and a frame frame. The frame frame is located on one side of the warp knitting machine body. The warp knitting machine body is equipped with a warp roller and multiple auxiliary guide rollers. The outer walls of the multiple auxiliary guide rollers and the warp roller are covered with the same fabric body. The frame frame is equipped with two mounting plates. Each mounting plate has a mounting hole on one side of its outer wall. Each mounting hole has an adjustment module inside it. The adjustment module includes two mounting discs, which are respectively connected to the inner walls of the two mounting holes. Each mounting disc has three sliding grooves on one side of its outer wall. Each sliding groove has a movable slider inside it. Each movable slider has an anti-drop-off module on one side of its outer wall.

[0007] The machine is equipped with a warping machine body, frame, warping rollers, mounting plates, fabric body, auxiliary guide rollers, anti-drop module, and adjustment module. The warping rollers and multiple auxiliary guide rollers improve the warping effect during use. The adjustment module allows for adjustment of the spacing between the tension rollers, accommodating different fabric thicknesses and enhancing the machine's performance. The anti-drop module ensures that if a rotating roller falls off, it can immediately clamp and stabilize the fabric, preventing it from becoming unusable due to lack of tension and wasting raw materials. It also prevents scratches and abrasions on the fabric surface, improving overall fabric quality.

[0008] In a preferred embodiment, the anti-detachment module includes multiple mounting posts, each fixedly connected to one outer wall of a plurality of movable sliders. Two mounting posts on the same movable slider have a common mounting ring fixedly connected to one outer wall. Limiting rings are fixedly connected to the inner walls of each mounting ring. Rubber airbags are provided on the inner walls of each limiting ring. A conveying pipe is provided on one outer wall of each rubber airbag. Arc-shaped mounting components are fixedly connected to the outer walls of each mounting ring. Air pressure sensors are fixedly connected to the tops of each arc-shaped mounting component. Display screens are provided on the tops of each air pressure sensor. Connectors are provided on one outer wall of each air pressure sensor, and the input ends of the connectors are connected to the output ends of the conveying pipes. Fixing rings are fixedly connected to both outer walls of each air pressure sensor. Electric push rods are fixedly connected to the inner walls of each fixing ring. Arc-shaped clamping plates are fixedly connected to the output ends of each electric push rod, and rubber pads are provided on one outer wall of each arc-shaped clamping plate.

[0009] By incorporating an anti-drop-off module, the system can promptly rotate the roller to clamp and stabilize it in case the rotating roller falls off during use. This prevents the fabric from being scrapped due to the inability to be properly pulled, thus avoiding waste of raw materials. At the same time, it can also prevent defects such as abrasions and scratches on the fabric surface caused by the rotating roller falling off, thereby improving the quality of the fabric.

[0010] In a preferred embodiment, each of the multiple sliding grooves has a circular hole on one side of its inner wall. A synchronous motor is fixedly connected inside each of the multiple circular holes. The output shafts of the multiple synchronous motors are connected to lead screws via couplings. One end of each lead screw is movably connected to one side of the inner wall of the multiple sliding grooves, and the outer wall of each lead screw is movably connected to the inner wall of the multiple movable sliders. Three rotating rollers are movably connected to the outer walls of opposite sides of the multiple movable sliders, and a traction roller is fixedly connected to the outer walls of each of the three rotating rollers.

[0011] The adjustment module allows for quick adjustment of the spacing between the pull rollers, enabling rapid adjustment based on different production tasks and fabric requirements. This eliminates the need for frequent replacement of equipment parts or complex debugging, improving production flexibility and adaptability. It also helps companies respond quickly to market demands, thereby increasing production efficiency and economic benefits.

[0012] As can be seen from the above, the adjustable-spacing warp knitting machine traction device provided by this utility model can promptly rotate the rollers to clamp and stabilize the fabric when the rotating rollers fall off, thus preventing the fabric from being scrapped due to the inability to be properly pulled and wasting raw materials. At the same time, it can also prevent defects such as abrasions and scratches on the fabric surface caused by the rotating rollers falling off, thereby improving the product quality of the fabric. In addition, by setting an adjustment module, the spacing between the traction rollers can be adjusted to adapt to the knitting of different fabric thicknesses, thereby improving the production efficiency of the equipment.

[0019] The present invention discloses a multi-tension roller adjustable warp knitting machine tensioning device, which is mainly used in scenarios where existing devices become loose due to wear during long-term use, leading to the detachment of tension rollers and adversely affecting the quality of warp knitting products.

[0020] Reference Figures 1-4 A warp knitting machine traction device with adjustable spacing of multiple traction rollers includes a warp knitting machine body 1 and a frame frame 2. The frame frame 2 is located on one side of the warp knitting machine body 1. The warp knitting machine body 1 is equipped with a warping roller 8 and multiple auxiliary guide rollers 7. The outer walls of the multiple auxiliary guide rollers 7 and the warping roller 8 are provided with the same fabric body 6. The frame frame 2 is equipped with two mounting plates 3. The outer walls of the two mounting plates 3 are provided with mounting holes. The two mounting holes are equipped with adjustment modules 4. The adjustment modules 4 include two mounting discs 401. The two mounting discs 401 are respectively connected to the inner walls of the two mounting holes. The outer walls of the two mounting discs 401 are provided with three sliding grooves 402. The sliding grooves 402 are equipped with movable sliders 403. The outer walls of the movable sliders 403 are equipped with anti-drop modules 5.

[0021] Reference Figure 1 , Figure 2 and Figure 4 In a preferred embodiment, the anti-detachment module 5 includes multiple mounting posts 501, which are respectively fixedly connected to one outer wall of multiple movable sliders 403. Two mounting posts 501 located on the same movable slider 403 have the same mounting ring 503 fixedly connected to one outer wall. Limiting rings 504 are fixedly connected to the inner walls of each mounting ring 503. Rubber airbags 506 are provided on the inner walls of each limiting ring 504. A delivery pipe 513 is provided on one outer wall of each rubber airbag 506. Arc-shaped mounting members 502 are fixedly connected to the outer walls of each mounting ring 503.

Each pressure sensor 510 has a connector 512 on one side of its outer wall. The input end of each connector 512 is connected to the output end of the delivery pipe 513. Each pressure sensor 510 has a fixing ring 509 fixedly connected to both sides of its outer wall. Each fixing ring 509 has an electric push rod 508 fixedly connected to its inner wall. Each electric push rod 508 has an arc-shaped clamping plate 505 fixedly connected to its output end. Each arc-shaped clamping plate 505 has a rubber pad 507 on one side of its outer wall.

[0022] Reference Figures 1-4 In a preferred embodiment, a circular hole is provided on one side of the inner wall of each of the multiple sliding grooves 402. A synchronous motor 407 is fixedly connected inside each of the multiple circular holes. The output shafts of the multiple synchronous motors 407 are connected to lead screws 406 through couplings.

[0023] Working principle: Start multiple synchronous motors 407, which drive multiple lead screws 406 to rotate. Under the action of the lead screws 406, multiple movable sliders 403 drive multiple rotating rollers 404 and multiple traction rollers 405 to move horizontally inside multiple sliding grooves 402, thereby adjusting the distance between the traction rollers 405.

[0024] The fabric body 6 is wound onto the outer wall of the warping roller 8 through the auxiliary guide roller 7 and the traction roller 405. The warping roller 8 is then started to begin warping the fabric body 6.

[0025] When a detachment occurs, the rotating roller 404 compresses the rubber air bladder 506. The change in air pressure inside the rubber air bladder 506 is transmitted to the air pressure sensor 510 through the conveying pipe 513. The electric push rod 508 is activated by the air pressure sensor 510, which pushes the two arc-shaped clamping plates 505 into contact with the rotating roller 404, causing the rotating roller 404 to stop rotating. The warping roller 8 is then removed, and the detached rotating roller 404 is replaced.
