Cable outer coating molding device and molding method

Abstract

The invention provides a cable outer coating molding device and molding method. The cable outer coating molding device comprises a host machine frame; the cable outer coating molding device further comprises a dipping bin, a natural curing bin, a heating bin and a guide wheel shaping bin which are sequentially disposed in the host machine frame along a cable conveying direction; the dipping bin isused for stirring and mixing raw materials, and coating the mixed raw materials on the outside of a cable, so that a cable outer coating can be obtained; the natural curing bin is used for performingnatural curing on the cable outer coating in the natural curing bin; the heating bin is used for performing heating semi-qualitative curing on the cable outer coating inside the heating bin; and theguide wheel shaping bin is used for shaping the cable outer coating in the guide wheel shaping bin according to a calibrated outer diameter size. With the cable outer coating molding device and molding method provided by the invention adopted, the integrated automatic molding of the cable outer coating is realized, a material utilization rate is improved, production costs are reduced, and the molding quality of cable products is improved.

Description

Technical field [0001] The invention relates to the technical field of cable molding, and more specifically, to a cable outer coating molding device and a molding method thereof. Background technique [0002] The outer cover of the wire and cable is usually continuously extruded on the outer surface of the conductor with a special device, so that the plastic or rubber material is wrapped on the conductor to form an outer layer to achieve the purpose of insulation and shielding electromagnetic interference. For some special cables that use a coating layer composed of thermoplastic polymer materials in order to improve the cable's fire resistance or strength, the outer molding at least includes the following steps: First, the extrusion includes at least one thermoplastic polymer and at least A dielectric liquid thermoplastic material; secondly, the thermoplastic material is passed through at least one static mixer; finally, the thermoplastic material is deposited and shaped around ...
