Description

Technical Field

[0001] The utility model relates to the technical field of pulling equipment, in particular to a pulling equipment used for manufacturing electric wires and cables. Background Art

[0002] In the manufacturing process of wires and cables, the commonly used pulling equipment is the traction machine. The traction machine is a device used in the manufacturing of wires and cables to stretch materials such as metal wires or copper wires through mechanical force. The working principle of the traction machine is to apply tension to the wire or cable through the rotation of the roller to stretch it. Through the use of the traction machine, the shape, size and physical properties of the material can be changed to meet the needs of wire and cable manufacturing.

The utility model can reel the cable by providing a winding device, and at the same time, by providing a pulling device, it can not only pull the cable and provide power to the cable during the transmission process, but also adjust the position and spacing of the pulling wheel, so as to realize the transmission of different cables, and the operator does not need to manually set the adjustment, which is more convenient and quick.

[0004] But the device still has the following defects:

[0005] When the device is in use, the cable may become loose during the cable winding process as the supply speed and the winding speed of the winding roller change, affecting the winding effect. When winding, since the cable delivery position is fixed and the winding position of the winding roller is also fixed, too much cable may be wound in one position. Therefore, we need to propose a pulling device for wire and cable manufacturing. Utility Model Content
