It relates to a chipping machine.

Wires and cables used in the electricity, telecommunications, and electronics industries are produced and used in various structures depending on their purpose of use.Wires and cables discarded after use (hereinafter referred to as closed wires) are made of copper wires (copper wires) and iron cores. The material is recycled by separating it from a synthetic resin material made of polyethylene (PE) or polyvinyl chloride (PVC) or a paper covering material covering the copper wire.

The method for separating the waste wire is largely divided into a method of incineration of the waste wire to extract only the copper wire and peeling off the covering material. However, the method of peeling off the coating material takes a lot of work time, so the labor cost is high, and the method of incineration causes various harmful gases such as toxic gas, soot and dioxin generated during incineration to pollute the environment. There was this.

Therefore, the present invention has been proposed to solve the fundamental problems of the prior art as described above, an object of the present invention can automatically separate the copper wire forming the iron core of the waste wire and the coating material surrounding the copper wire without generating harmful gas. The present invention provides a transformer copper chipping machine that can reduce environmental pollution and reduce costs.

In order to achieve the above object, the present invention includes a grinding means for cutting and grinding the waste wire to be separated into a coating material and copper wire; Classification means for receiving the copper wire and the covering material of the waste wire separated by the crushing means and separating the covering wire and the copper wire, respectively; Provided is a transformer copper wire chipper, comprising: a conveying means for transferring the covering material and copper wire of the electric wire cut and crushed by the crushing means to the separating means.
