A cutting blade 9 is fixedly connected to one side of the bottom surface of the top of the peeling frame 8. A positioning seat 10 is provided on one side of the cutting blade 9.

An overlapping block 23 is fixedly connected to one end of the sliding rod 21. A cam 24 is slidably connected to the bottom of the overlapping block 23. A friction roller 25 is fixedly connected to the middle of one side of the cam 24. The bottom surface of the support base 17 is fixedly connected to the top of the cylinder 26. The frame 19 is located at the end of the support base 17 away from the positioning bracket 2. The sliding groove 20 is symmetrically opened on both sides of the separation frame 19. The limiting block 22 is located in the middle of the separation frame 19. The overlapping block 23 and the cam 24 are symmetrically arranged on both sides of the separation frame 19. The two ends of the friction roller 25 are rotatably connected to the two sides of the lower end of the separation frame 19, respectively. By setting the separation frame 19 at the end of the support base 17, and driving the friction roller 25 to rotate through the outer insulation layer 15, the lifting and lowering of the limiting block 22 is provided, thereby facilitating the separation of the outer insulation layer 15 and the cable core 16 of the power cable.

[0032] Working principle: When using this power cable insulation stripper, first, place one end of the power cable above the support base 17, and make the outer insulation layer 15 of the power cable contact the top surface of the friction roller 25, and connect the outer insulation layer 15 to the winding roller 27, and let the cable core 16 pass through the limiting block 22 in the middle of the separating frame 19.

[0033] Secondly, the cylinder 26 at the top of the control base 1 extends, thereby causing the support base 17 to move the power cable towards the upper end of the positioning bracket 2 and the stripping frame 8. This causes the power cable to push the guide seat 6, the lifting rod 3 and the connecting rod 4 upward through the guide ball 7. The positioning seat 10 moves to one side of the stripping frame 8. At this time, the positioning spring 5 contracts. Then, the cutting blade 9 passes through the relief groove 11 and inserts into the upper end of the outer insulation layer 15, and the connecting block 12 contacts the upper end of the cable core 16. The guide plate 13 and the separation plate 14 unfold the inner side of the outer insulation layer 15.

[0034] Finally, the power supply of motor 28 is turned on, so that the take-up roller 27 drives the outer insulation layer 15 to slide on the friction roller 25, thereby causing the friction roller 25 to drive the cam 24 to rotate, and the cam 24 pushes the overlapping block 23 and the sliding rod 21 to slide in the sliding groove 20, thereby causing the limiting block 22 to drive the cable core 16 to rise, thus promoting the separation of the cable core 16 from the outer insulation layer 15. At this time, the power cable slides on the guide ball 7 and the moving ball 18, achieving the effect of continuous peeling of the power cable insulation layer.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
