Description

A device for removing the sheath on waste cables

technical field

The invention relates to the technical field of cable processing equipment, in particular to a device for removing sheaths on waste cables.

Background technique

The cable is usually twisted by several or several groups of wires, each group of wires is insulated from each other, and is often twisted around a center, and the entire outside is covered with a highly insulating covering. The cable has the characteristics of internal electrification and external insulation.

In the cable production process, due to problems such as uneven cable sheath, uneven wire diameter, and unqualified transition color, these cables are often treated as waste products, which results in waste of conductor cores.

A cable stripper is disclosed in Chinese patent application number: 201420305211, which includes a main half-pipe and a secondary half-pipe that are locked into a sleeve by a locking device, and a power that is tightly fitted with the cable sheath is installed in the power chamber of the sleeve. The gear and the motor that drives the power gear rotate. A switch that controls the power on and off of the motor is provided on the outer wall of the casing. A knife handle is slidingly inserted, and the inner end of the knife handle is fixed with a blade capable of longitudinally cutting the cable. The outer section of the blade cavity is screwed with a positioning device for axial positioning of the knife handle, and a connecting ring is fixed at the end of the sleeve. This technical solution does not correct the bending of the cable during the stripping operation, resulting in an unsatisfactory stripping effect. Moreover, the separation effect of the sheath on the cable and the cable core is not ideal, and it cannot be flexibly used for cables of different diameters. Clamping and peeling operations cannot simultaneously clamp multiple cables for operation, and this technical solution needs further improvement.
