Copper core PVC insulated cable processing device

Abstract

The invention relates to the field of cable processing equipment and discloses a processing device for copper-core polyvinyl chloride insulated cable, comprising a frame, wherein, a paying-off roller,an extrusion mechanism, a cooling mechanism and a take-up roller are fixed on the frame; the extrusion mechanism comprises a screw extruder and a wire conveying pipe; a feeding port is arranged in the side wall of the wire conveying pipe; and a pre-cooling mechanism is arranged on the wire conveying pipe. A bearing is slidably connected in that transmission line pipe, a hollow transmission spoolis rotatably connected with the bearing, a first negative pressure blade is fixed on one end of the hollow transmission spool, a third gear is fixed on the hollow transmission spool, the third gear meshes with a fourth gear, the fourth gear is coaxially connected with a cylindrical cam, the ejector rod is rotatably connected with the third gear, the cylindrical cam and the ejector rod are in contact with each other, and the transmission pipe is provided with a collection hole; In order to solve the problems of high labor intensity and long time consuming for operators to clean PVC in the priorart, 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 field of cable processing equipment, in particular to a processing device for copper core polyvinyl chloride insulated cables. Background technique [0002] When processing copper core PVC insulated cables, generally put the twisted copper core wires on the pay-off roller, then pass the wires through the extrusion mechanism and cooling mechanism in turn, and finally connect with the take-up roller; the wires pass through During the extrusion mechanism, the conductor is coated with polyvinyl chloride through the extrusion mechanism, and the conductor coated with polyvinyl chloride is pre-cooled, so that the liquid polyvinyl chloride is initially formed on the conductor; The wires of the polyvinyl chloride layer enter the cooling mechanism for further cooling, so that the polyvinyl chloride is molded on the wires to obtain cables, and finally the cables are stored by the take-up roller. [0003] The extruding mechanism used ...

AI Technical Summary

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
