The upper halves of the front bracket 13 and the rear bracket 14 are respectively arranged in an arched structure. When the transmission structure drives the rotary cutting turntable 2 to rotate at a low speed, the front and rear multiple groups of connecting guide pillars 15 will slide synchronously along the inside of the annular groove, so that the front bracket 13 and the rear bracket 14 can provide support and limitation from the front and rear ends of the rotary cutting turntable 2; the cable itself The body 12 respectively crosses the inner sides of the front bracket 13 and the rear bracket 14, and the second fixed sleeve 10 is fixedly connected to the inner two sides of the front bracket 13 respectively. The second fixed sleeve 10 is clamped with a second cutter 18 near the middle position of the front bracket 13. A group of second cutters 18 is provided. Since the blades of a group of second cutters 18 are relatively arranged, when the skin of the photovoltaic power source is peeled and pulled out from the back to the front, a group of second cutters 18 will come into contact with the skin of the photovoltaic cable and cut the skin into two, so that the skin can be quickly detached.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, the cable body 12 crosses the inner side of the heating sleeve 3 and extends to the middle position of the rotary cutting turntable 2, and flame spray guns 17 are fixedly installed at the four corners of the heating sleeve 3. A flame spray tube 16 is provided near the middle position of the heating sleeve 3. The ignition end of the flame spray tube 16 extends and inserts into the middle position of the heating sleeve 3. When the photovoltaic cable crosses the inner side of the rotary cutting turntable 2, as the rotary cutting turntable 2 realizes synchronous low-speed rotation, multiple flame spray guns 17 will be evenly sprayed onto the surface of the photovoltaic cable through the flame spray tube 16, so that its surface can be heated and softened; one side of the tooth 4 is meshed and connected with Gear 5, and the front end of the gear 5 is connected to a driving motor 6, the driving motor 6 is connected through the gear 5, the teeth 4 and the rotary cutting disc 2, the rotary cutting disc 2 and the first cutter 9 are adjacent to each other in front and back positions, and the first cutter 9 is distributed in a circular array along the center point of the rotary cutting disc 2, the bottom end of the first cutter 9 is a pointed structure, and the ear plate 8 and the rotary cutting disc 2 are limited to be fixedly connected by bolts, when the driving motor 6 starts to run and drives the gear 5 to rotate, the mutual cooperation between the gear 5 and the teeth 4 enables the rotary cutting disc 2 to be subjected to force, so as to rotate with the heating structure and the rotating structure.

When using the hot cutting equipment to cut the skin of the photovoltaic cable, the cable body 12 released from the winding device can first be introduced into the equipment from the back to the front, and then one end of it can be connected to the external traction device. As the external traction device pulls the photovoltaic cable from the back to the front, and the equipment starts the drive motor 6, it can be driven by the teeth 4 and the gear 5 to achieve low-speed rotation with the heating structure and the rotary cutting structure. The hot cutting equipment will first open the flame spray gun 17, The photovoltaic cable is preheated and softened by the flame ejected from the flame-throwing tube 16. Then, under the tightening and limiting action of the first fixed sleeve frame 7 and the limiting ear plate 8, the hot cutting equipment uses a plurality of first cutters 9 rotating at a low speed to quickly cut the skin of the photovoltaic cable. When the photovoltaic cable continues to be brought forward and crosses the front bracket 13, a group of second cutters 18 near the middle position of the front bracket 13 will cut the skin of the photovoltaic cable, so that the skin is divided into two and quickly falls off the photovoltaic cable. The entire heating and cutting operation is completed.
