Description

Technical Field

[0001] The invention relates to the technical field of cable peeling and recycling equipment, in particular to a waste cable peeling and recycling device. Background Art

[0002] Before recycling cables, the cables need to be stripped and the metal core inside needs to be recycled. At present, cable recycling devices generally use a pair of blades set opposite to each other to insert into the cable skin, cut the cable skin with the blades, and then take out the internal metal core for recycling. However, in actual application, it is found that for cables with larger diameters, it is easier to achieve the method of stripping with blades, but this method not only wastes manpower, but also has low efficiency.

[0003] The patent with announcement number CN 105140831 B discloses a cable stripping device, which is used to strip abandoned cables for recycling. It includes a tool assembly layer, a clamping assembly, a translation assembly, a crossbeam, a support frame and a lifting assembly. The tool assembly includes a lower bracket, a tool, a first slider and a tool driving mechanism. A cover plate is fixed on the top of the left side of the lower bracket, and a first slider is slidably installed on the cover plate. A tool is fixed on the first slider. A tool driving mechanism for driving the first slider to move back and forth is provided in the inner cavity of the lower bracket; an upper bracket is provided above the lower bracket, and a second slider is slidably installed at the lower part of the upper bracket. A translation assembly for driving the second slider to move back and forth is provided between the second slider and the upper bracket; a crossbeam is provided below the second slider, and a lifting assembly for driving the crossbeam to move up and down is provided between the second slider and the crossbeam; a clamping assembly for clamping the cable is provided at the lower part of the crossbeam. The device can effectively realize the stripping operation of abandoned cables. However, the invention only uses a reciprocating cutter to peel the cable, the peeling efficiency is low, and more peeling residues are left, resulting in poor effect.

[0004] The patent with announcement number CN 106329410 B discloses an operating method of an electric stripping device for protecting the core of waste cables. Clamping mechanisms are arranged at both ends of an operating table. A heater, a skin cutting mechanism, and a skin stripping mechanism are arranged in sequence between the two clamping mechanisms along the cable running direction. An insulation layer collecting hole is arranged between the skin cutting mechanism and the skin stripping mechanism. First, the height of the telescopic rod on the clamping mechanism is adjusted, and then the distance between the blade of the cutting blade on the skin cutting mechanism and the cable inner core is adjusted, and the distance between the blade of the separating sheet on the skin stripping mechanism and the cable inner core is adjusted. Finally, the center of each mechanism is adjusted to be located on the same axis line. After that, the insulation layer of the processed cable is heated, skin cut, and skin stripped in sequence. The structure is simple, the operation method is simple, the use effect is good, the worker is easy to operate, the labor intensity of the worker is greatly reduced, the stripping effect is good, the production efficiency is high, it is suitable for stripping the rubber of various cables, and the cable core recovery efficiency is high. However, the invention arranges the heater in front of the skin cutting mechanism, and heats, skins and peels the cable in sequence, which easily causes problems of incomplete skin cutting and insulation skin congestion during skin cutting. It is not convenient to use and the stripping effect is not good. Summary of the invention

[0005] In view of this, the present invention aims at the deficiencies in the prior art and provides a waste cable peeling and recycling device which has the advantages of smooth and thorough cable stripping, labor saving and high efficiency.
