Cable processing system

Abstract

The invention discloses a cable processing system, comprising: a plastic extrusion apparatus, a drawing apparatus, and a cooling apparatus arranged between the plastic extrusion apparatus and the drawing apparatus. A coloring plate is arranged between the plastic extrusion apparatus and the cooling apparatus. The coloring plate is of a rectangular structure and is provided therein with a plurality of parallel concave grooves. The two side faces of the coloring plate opposite to the two ends of the concave grooves are provided with a wire inlet hole and a wire outlet hole corresponding to the concave grooves and the diameter of the wire outlet hole nearing one side of the cooling apparatus is 0.5 to 1 mm larger than the diameter of the wire inlet hole of the other side face. The diameter of the wire inlet hole on the coloring plate nearing one side face of the plastic extrusion apparatus is 0.5 to 1 mm larger than the diameter of a to-be-processed core wire. Firstly, a cable is extruded for an insulation layer through the plastic extrusion apparatus, then subjected to the coloring process by the coloring plate and then, cooled through the cooling apparatus, and finally, formed into a plate through wire collection. In the entire process, the coloring plate plays the coloring function, which increases the production efficiency, avoids the waste of the color master batch and ensures the insulation effect of the cable.

Description

technical field [0001] The invention relates to the field of special machinery for the production of cables, in particular to a cable processing system. Background technique [0002] At present, in the cable production process, it mainly includes a core wire extruder, a cooling water tank, a tractor and a control system. The water tank is cooled, and finally the wires are collected into a coil; however, in the production process of cross-linked cables, a layer of color needs to be placed on the insulating layer to distinguish the cables, and the extrusion material of the insulating layer is silane cross-linking material, and the color of the insulating layer It is made by adding polyethylene masterbatch to silane cross-linking material. Since silane cross-linking material can be cross-linked in warm water or at high room temperature, the silane cross-linking material cannot stay in the extruder barrel for too long, otherwise Pre-crosslinking will occur, which will affect th...
