[0002] The tensioning mechanism is a commonly used mechanical device, which is mainly used to maintain the relative position and spacing of the connected parts and increase the friction. Its working principle is based on the application of mechanical force.

In traditional winding machines, the lack of a tensioning mechanism causes the winding to be loose, affecting the quality of the finished product, or the design of the tensioning mechanism is insufficient, such as high maintenance costs, and regular inspections and adjustments are required to ensure its normal operation. In addition, different types of tensioning mechanisms may be required for different types of wires and coils, which also increases the complexity and cost of the equipment. Utility Model Content
