High-efficiency cooling device used before cable plastic molding

Abstract

The invention discloses an efficient cooling device before cable plastic molding, which comprises traction mechanisms arranged at the two ends of a contact type cooling mechanism and used for pulling a thick wire to continuously pass through the contact type cooling mechanism, and the cooling mechanism comprises a cooling groove, a lifting device and a reverse twisting type contact device, through the winding effect that the reverse twisting type contact device reversely rotates around the twisting direction of the thick wire to temporarily make contact with the thick wire, the surface of a small wire on the thick wire makes complete contact with talcum powder, the cooling protection effect on the thick wire is improved, the thickness of the thick wire is reduced, and the service life of the thick wire is prolonged. The problems that the service life of the cable is shortened and the use safety is reduced due to the fact that the thick wire is heated and adhered during plastic molding are solved, and the reverse twisting type contact device and the thick wire move synchronously, so that the influence on the production efficiency of cable processing is avoided.

Description

technical field [0001] The invention relates to the technical field of cable manufacturing, in particular to a high-efficiency cooling device before cable plastic molding. Background technique [0002] Cable is a kind of electric energy or signal transmission device. It is usually made of several or several groups of wires twisted together. Each group of wires is insulated from each other. The manufacturing process of cables includes single wire winding, small wire plastic, small wire winding and large wire winding. Line plastic, etc. In the large line plastic process, the granulation is heated and melted, and the plastic molding is completed by wrapping it outside the large line. [0003] In the existing large-wire plastic process of cables, in order to avoid thermal adhesion between the small wire and the outer insulating sleeve and the plastic surface of the small wire and the small wire in order to avoid the thick wire wound by the small wire, resulting in cable In orde...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a high-efficiency cooling device before cable plastic molding, which solves the problem of the occurrence of small wires between small wires due to the failure of part of the surface to contact with talcum powder when the existing cables are plastic-molded during the manufacturing process. heat sticking problem
