Problems solved by technology

[0004] The above scheme has the following problems. When the outgoing line is about to end, in order to cover all the wires with polyvinyl chloride, after the line pipe exits, the extruder stops extruding polyvinyl chloride, which will cause some redundant The polyvinyl chloride remains in the pipeline. After many times of operations, the accumulated polyvinyl chloride may block the outlet side of the pipeline. In the past, the method of cleaning polyvinyl chloride was manual cleaning, and the operator had to rely on external Equipment, forcibly impacting the polyvinyl chloride that has been molded on the pipeline wall, and the strength and toughness of polyvinyl chloride after molding are relatively high, and the operator not only needs to spend a lot of effort, but also takes a long time , in order to break through the polyvinyl chloride that has been formed on the pipeline wall, the operation is very troublesome, increases the labor intensity of the operator, and reduces the efficiency of cable production

Abstract

The invention relates to the technical field of cable processing, and discloses a manufacturing process of a copper-core PVC insulated cable, comprising the following steps: A, monofilament drawing; B, monofilament anneal; C, twist; D, squeeze a bag; E, cool; F, clean; In order to solve the problems of high labor intensity and long time consuming for operators to clean PVC in the prior art, the scheme reduces the labor intensity of operators and improves the cleaning efficiency by making the first negative pressure blade rotate reciprocally and slidably.

Description

technical field [0001] The invention relates to the technical field of cable processing, in particular to a manufacturing process of a copper core polyvinyl chloride insulated cable. Background technique [0002] When processing copper-core PVC insulated cables, the twisted copper-core wires are generally placed on the pay-off roller, and then the wires need to go through the extrusion process and the cooling process in turn, and finally connect to the take-up roller; During the wrapping process, the wires are covered with polyvinyl chloride by the extrusion mechanism, and the wires covered with polyvinyl chloride are pre-cooled, so that the liquid polyvinyl chloride is preliminarily formed on the wires; The lead wire of the vinyl chloride layer enters the cooling mechanism for further cooling, so that the polyvinyl chloride is formed on the lead wire to obtain a cable, and finally the cable is received by a take-up roller. [0003] The extrusion process in the prior art re...
