A system for producing copper strips from waste single-core cables

Abstract

The invention discloses a system for producing a copper strip by an old single-core cable, which is used for recycling waste. The system comprises an unreeling machine, a steering shaft, a tension pulley, a stripping roller assembly, a traction device, a high-frequency heating device, a rolling device, a polishing machine and a reeling machine, which are sequentially arranged from front to back, wherein the stripping roller assembly comprises a knife roller and a carrier roller, which are arranged up and down in pairs; the knife roller is located at the upper side and comprises a plurality of cutter wheels; the cutter wheels are fixed on a knife roller shaft through keying fit; each cutter wheel comprises left and right two sheets; a blade is clamped in the middle; each blade comprises an annular part and a knife point part; four knife point parts are arranged in all; and a heating device is arranged at the rear side of each knife roller. Through a non-damage stripping technology, a cable sheath is stripped; and the surface of a copper core is not damaged, so that a relatively good guarantee can be brought for subsequent copper strip production.

Description

technical field [0001] The invention relates to the recycling technology of waste cables in the field of electric power technology, specifically a system for producing copper strips from waste cables. Background technique [0002] Regarding the recycling of waste cables, take a cable with a cross-section of 6 square millimeters as an example. The cable core generally uses a single copper core. Due to its simple structure, it only has a copper core and a sheath. is recyclable. [0003] The methods currently used mainly include the following three methods. One is the incineration method, that is, the skin is directly burned to leave the exposed copper core, and the high-value copper core is recycled. This method pollutes the environment. The second is the mechanical peeling method, that is, the outer skin is peeled off with a blade to separate the two. Whether it is mechanical peeling or manual peeling, there is a problem that the tool will leave more or less scratches on the...

[0004] Another example is a Chinese patent application number of 201410123585.6, which is based on a water jet recycling waste wire and cable device. It uses high-pressure pure water jets to recycle waste wire and cable. It is clean, environmentally friendly, easy to operate, and low in cost. Efficient recycling of materials, using a nozzle to continuously spray the cable back and forth through the arc trajectory, while the efficiency is low, there is no cable in most of the area of ​​​​the trajectory, that is to say, only the few moments that are sprayed onto the cable are really effective , wasting most of the energy and time on the trajectory of the jet
