Description

Technical Field

[0001] This utility model relates to the field of traction devices for cable processing, and more specifically, to a traction device for cable processing. Background Technology

[0002] Cables have many uses, mainly for control installation, equipment connection, power transmission and other functions. They are a common and indispensable thing in daily life. However, communication cables are used all over the world. In the production and processing of cables, cable processing traction devices are needed to pull or wind the cables. In traditional technology, such as the cable processing traction mechanism proposed in publication number CN 110902491 B. The device includes a take-up roller for winding the cable and a traction motor for driving the take-up roller to rotate. A support platform is provided on one side of the input end of the take-up roller, and a traction frame is fixedly installed on the top of the support platform. A guide wheel and a tensioning mechanism for cable tensioning are installed on the inner side of the traction frame. One end of the tensioning mechanism is rotatably connected to the guide wheel. The tensioning mechanism includes a third tensioning member, a second tensioning member, and a first tensioning member. The elasticity of the third tensioning member, the second tensioning member, and the first tensioning member decreases sequentially along the cable conveying direction. When there is a speed difference in the winding of the cable, and the cable itself is pulled, the first tensioning member, which is closest to the take-up roller and has the least elasticity, will contract first. Then the second tensioning member and the first tensioning member will contract sequentially to increase the buffer distance of the cable, making the tensioning mechanism more responsive and reducing the change in tension on the cable.

[0003] According to existing technology, such as the present invention disclosed in patent announcement number CN222860791U, a traction device for cable processing includes a base with universal wheels at the four corners of the bottom. An adjustment assembly is located inside the base, and two support plates are movably fitted inside the top of the base. The adjustment assembly includes a bidirectional screw movably fitted inside the base. A servo motor is located on one side of the bidirectional screw, which drives the bidirectional screw to rotate. Two movable seats are threaded onto the external threads of the bidirectional screw. This invention uses the output shaft of the servo motor to drive the bidirectional screw to rotate clockwise or counterclockwise, thereby causing the two movable seats threaded onto the external threads of the bidirectional screw to move towards or opposite directions. This causes the connecting rod connected to the movable seats to move the top plate up and down along the limiting rod, thereby causing the support plate traction box at the top of the top plate to move synchronously with the traction box, thus enabling adjustment of the traction box height.

[0004] The aforementioned patent uses a complex structure for lifting and adjusting the cable. No height adjustment is required when the cable is pulled. The aforementioned patent is costly and inconvenient to maintain. In addition, the elastic mechanism supports the extrusion roller. The cables are of different thicknesses, and the elastic extrusion is not tight, making it easy to shake and loosen. This makes it impossible to effectively extrude and rotate for traction, and the traction structure is unstable. Utility Model Content
