Description

Technical Field

[0001] The utility model relates to the technical field of wire tension control, in particular to a wire tension control device for a shaft-joining machine. Background Art

[0002] The weaving machine is a device used in the weaving process and is a common device in the textile field. It is a common machine that combines the silk threads left on the sizing shaft after sizing and winds them onto the weaving shaft. Since the silk threads are affected by many external forces, such as tensile force, bending force, etc., the silk threads are prone to bending, breaking, and other problems, which in turn affects the quality and production efficiency of the weaving of the silk threads. Therefore, a certain reverse pulling force needs to be applied to the silk threads to prevent them from bending and breaking.

[0003] When adjusting the tension of the silk thread, it is generally achieved by adjusting the tension adjusting wheel. By changing the position of the tension adjusting wheel, the silk thread tension is adjusted. For example, Patent No. CN210393247U discloses a yarn tension adjusting device for textile processing. By inserting the rotating shaft on the tension adjusting wheel frame into the shaft sleeve at a suitable position, the position of the tension adjusting wheel frame is changed, thereby achieving the purpose of adjusting the silk thread tension. However, when adjusting, the loose silk thread needs to be removed first, and then the tension adjusting wheel frame is removed as a whole and fixed in a suitable position. The operation is relatively troublesome and cannot automatically adjust and control according to the situation of the silk thread. Utility Model Content
