Cable processing machine

Abstract

The invention discloses a cable processing machine which comprises a plastic extrusion device, a traction device and a cooling device therebetween. A coloring disk of a rectangular structure is arranged between the plastic extrusion device and the cooling device, grooves are arranged in parallel in the coloring disk, wire inlets and wire outlets corresponding to the grooves are formed in two side surfaces, in the two opposite ends of the grooves, of the coloring disk, the diameter of the wire outlets in the side surface close to the cooling device is greater than that of the wire inlet in the other side surface for 0.5 to 1mm, and the diameter of the wire inlets in the side surface close to the plastic extrusion device is greater than that of a core wire to be processed for 0.5 to 1mm. The plastic extrusion device extrudes an insulating layer of a cable, the coloring disk carries out coloring on the cable, the cooling device carries out cooling on the cable, and the cable is taken up into a disk; the coloring disk is used for coloring in the whole process, the production efficiency is improved, waste of color masterbatch is avoided, and the insulation effect of the cable is ensured.

Description

technical field [0001] The invention relates to the field of special machinery for the production of cables, in particular to a cable processing machine. 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 t...

[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 the insulation quality of the cable core, or the silane material cannot be extruded from the extruder. At the same time, due to the process requirements, the cable core insulation layer needs to be changed to a different color, so it is necessary to replace one color After emptying the extruder and then adding silane material and corresponding color masterbatch, the waste phenomenon is very serious and the production efficiency is low.
