A high-efficiency cooling device before cable plastic molding

Abstract

The invention discloses a high-efficiency cooling device before cable plastic molding, which is equipped with a traction mechanism, which is arranged at both ends of the contact type cooling mechanism, and is used for pulling the thick wire to continuously pass through the contact type cooling mechanism. The mechanism includes a cooling tank, a lifting device and an anti-twisted contact device. One end of the lifting device along the lifting direction is arranged on the cooling tank. The winding effect of contacting the thick wire makes the surface of the small wire on the thick wire fully contact with the talcum powder, which improves the cooling protection effect on the thick wire and avoids the thermal adhesion of the thick wire during plastic molding. The service life is reduced and the safety is reduced. Secondly, the anti-twisted contact device moves synchronously with the thick wire, which avoids the impact on the production efficiency of cable processing.

Description

technical field [0001] The invention relates to the technical field of cable manufacturing, in particular to a high-efficiency cooling device for cables before plastic molding. Background technique [0002] A cable is a power or signal transmission device. It is usually formed by twisting several or several groups of wires. Each group of wires is insulated from each other. The manufacturing process of the cable includes monofilament winding, small wire plastic, small wire winding and large wire. Line plastic, etc., in the large line plastic process, by heating and melting the granulation, the plastic molding is completed by wrapping outside the large line. [0003] In the existing large wire plastic process of the cable, in order to prevent the thick wire wound from the small wire from being heated and adhered between the small wire and the outer insulating sleeve and the plastic surface of the small wire and the small wire during the plastic process, resulting in the cable ...

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
