Technical Field

The invention belongs to the technical field of communication cables, and particularly relates to a torsion wire loosening device for a communication cable stripping machine.

Background

The communication cable is composed of a cable core and a protective layer, wherein the cable core is a main part for bearing information transmission, and the protective layer is required to be added outside the cable core in order to protect the cable core from being affected with damp and external mechanical damage and electrical interference.

In the prior art, when a communication cable is peeled, a peeler is usually used, most of the traditional communication cable peelers directly scratch the communication cable skin through a cutting blade to peel the communication cable, however, because the old communication cable is used for a long time, the insulation skin and the cable core are tightly attached or even adhered together, the problems of difficult cutting and incomplete peeling often occur, the working efficiency is reduced, and the cutting blade is greatly damaged, so that the communication cable needs to be loosened through a wire loosening device.

Therefore, we propose a torsion wire releasing device for a communication cable stripping machine to solve the above problems.
