Description

Automatic cable stripping machine

Technical Field

The invention relates to the field of fruit and vegetable production, in particular to an automatic cable stripping machine.

Background

A cable is a conductor made of one or more conductors insulated from each other and an outer insulating sheath that carries power or information from one location to another. After the cable is used, the cable can be recovered, but the insulation protective layer needs to be peeled off from the metal conductor during recovery, so that the plastic protective layer and the metal conductor can be classified and recovered. The wire stripper is a machine for stripping a plastic sheath and a metal core which are wrapped outside an electric wire and the like, but the conventional wire stripper can easily cut an insulating protective layer, but the insulating protective layer is difficult to strip from a metal conductor, manual stripping is usually required, and the manual efficiency is very low. Even the stripped insulating protective layer is intermittent and scattered, the classified recovery of the plastic protective layer and the metal conductor is difficult to realize really and quickly, the operation is very troublesome, the labor force is wasted, the manual operation consumes time, and the recovery efficiency is reduced. Therefore, it is desirable to design a wire stripper that can automatically cut the insulation.
