[0002] Old cables are scrap cables retired from the power system, and the replaced old cables need to be stripped. The main purpose is to separate the metal (such as copper) and the insulating material (such as polyvinyl chloride) in the cable so that they can be recycled and reused separately.

[0003] There are many stripping methods, including manual stripping, mechanical stripping, chemical method and freezing method. Manual stripping method: low efficiency and high cost, generally not recommended for large-scale use. Mechanical stripping method: use a cable stripping machine for processing, suitable for processing thicker cables, high efficiency but may still require manual assistance. Chemical method: use chemical liquid to dissolve the cable sheath, which will not harm the metal wire inside, but will produce chemical waste liquid, which needs to be properly handled. Freezing method: use refrigerants such as liquid nitrogen to make the cable brittle, and then separate the cable sheath and metal wire segments by crushing. The most commonly used method is the mechanical stripping method, such as the Chinese invention patent with publication number CN116470445A, which discloses a stripping device for recycling waste cables, including a cable preheating device, a cable skin cutting device, and a collecting device; the cable preheating device includes a first heater; a heat conducting plate is arranged at the bottom of the heater, and the heat conducting plate is connected to the heat conducting shell; the left side of the heater is connected to a fixed block; the left side of the fixed block is connected to a movable nut; the movable nut is arranged on a screw rod; the cable skin cutting device includes a cylinder; a second heater is arranged at the bottom of the cylinder; and a cutter head is connected to the bottom of the second heater.

The fixed roller 71 is installed at the rear end. In the process of collecting the cable sheath on the second take-up drum 12, the pulling end 811 of the cable sheath 81 is attached to the fixed roller 71. The fixed roller 71 and the movable roller 72 are rotatably connected to the support frame 6, wherein the axial center distance of the movable roller 72 and the axial center distance of the fixed roller 71 are adjustable. The movable roller 72 is elastically connected to the support frame 6 and abuts against the circumferential surface on the other side of the pulling end 811 of the cable sheath 81 through the elastic connection. The elastic connection of the movable roller 72 to the support frame 6 is a conventional technical means and will not be introduced in detail here.

[0019] The peeling and cutting mechanism assembly 3 includes a V-shaped support roller 36 installed on the support frame 6, a first telescopic cylinder 32 is correspondingly installed on the support frame 6 above the V-shaped support roller 36, a lower pressure roller row 33 is installed at the input end of the first telescopic cylinder 32, a peeling device 35 is installed in the middle part of the lower pressure roller row 33, a material box 34 is correspondingly installed on the input port of the peeling device 35, a guide column 37 is installed on the lower pressure roller row 33, the guide column 37 is slidably connected to the support frame 6, and a cutting knife 31 is installed at the tail end of the lower pressure roller row 33.

[0032] Step two, the scraping and cutting mechanism assembly 3 clamps the cable 8. After clamping, the traction mechanism 5 is started, and the cable 8 is pulled inward by the driving wheel 52. At this time, the first heater 4 heats the cable 8 for the first time, so that the cable skin 81 softens. The softened cable skin 81 enters the scraping and cutting mechanism assembly 3 and is easier to be cut by the cutting knife 31. At this time, the cut cable 8 enters the separation mechanism 7, and the cable skin 81 is easier to be stripped off the cable 8 through the second heater 2.

[0033] Step three, the collecting mechanism 1 collects the cable core 82 and the cable sheath 81 respectively, so as to facilitate the later transportation.
