Description

Technical Field

[0002] In the production process of network cables and signal cables, if the movement of the wires depends entirely on the power provided by the winding at the end, the wires are prone to breakage. Therefore, a traction mechanism is provided to assist in traction and ensure the normal production of the wires. During the installation and use of the existing traction mechanism, a motor is required to drive the driving wheel. The compression belt that fits the driving wheel rotates under the action of static friction. After that, the worker inserts one end of the wire between the belt and the power wheel from the side.
