The support sliding block 55 is slidably connected to the outside of the support rod 52 and is provided with an inner protrusion. The inner protrusion penetrates and is slidably connected to the inside of the connecting groove 56. Threaded teeth are formed on the inner side of the inner protrusion. A fixed screw rod 57 is rotatably connected to the inside of the support rod 52 and is threadedly connected to the inner protrusion. The fixed screw rod 57 penetrates the mounting plate 4 and is fixedly connected to an operating handle 58 at the outer side of the mounting plate 4.

[0042] The connecting rod 53 is formed in a “h” shape and is hingedly connected. The bottom feet of the “h” shape are hingedly connected to the movable plate 51 and the support rod 52, respectively. The top end of the “h” shape is hingedly connected to the telescopic rod 54.

[0043] The fixing mechanism 5 is used for fixing rubber pipes with different diameters. The fixing process is as follows. The rubber pipe is sleeved on the outside of the movable plate 51. The operating handle 58 is rotated to drive the fixed screw rod 57 to rotate. The fixed screw rod 57 drives the support sliding block 55, which is threadedly connected to the fixed screw rod 57, to slide on the outside of the support rod 52. The support rod 52 pushes the connecting rod 53, so that the movable plate 51 moves outward to adapt to the fixing of rubber pipes with different diameters, thereby effectively increasing the range of the fixing mechanism 5 for fixing rubber pipes.

[0044] The inside of the rotating ring 82 is rotatably connected to a positioning ring 88. An adjusting groove 89 is formed in the side of the positioning ring 88. An adjusting arc tooth 810 is fixedly arranged on the inner side of the positioning ring 88. An adjusting cutter gear 811 is meshingly connected to the outside of the adjusting arc tooth 810. An adjusting hole column 812 is fixedly connected to the outside of the adjusting cutter gear 811. A clamping block 8121 is hingedly connected to the inside of the adjusting hole column 812.

[0045] The cutter blade clamp 84 is slidably connected to the inside of the rotating ring 82. The positioning pin 87 is slidably connected to the inside of the adjusting groove 89. The adjusting groove 89 is designed to be inclined away from the center. The adjusting hole column 812 is rotatably connected to the rotating ring 82.

[0047] According to the outer diameter of the rubber tube and the required stripping depth, the cutting depth is calculated, and the position of the blade clamp 84 is adjusted according to the cutting depth. When adjusting, the adjusting rod 8123 is inserted into the adjusting hole column 812. During the insertion of the adjusting rod 8123, the adjusting rod 8123 pushes the clamping block 8121, causing the clamping block 8121 to compress the spiral spring 8122 and deflect. The clamping block 8121 is disengaged from the clamping groove 821, so that the adjusting hole column 812 is conveniently rotated. The adjusting hole column 812 is rotated by rotating the adjusting rod 8123, which drives the adjusting hole column 812 to rotate. The adjusting hole column 812 drives the cutter gear 811 to rotate, which drives the positioning ring 88 to rotate through the adjusting arc tooth 810. During the rotation of the positioning ring 88, the blade clamp 84 is driven to slide in the rotating ring 82 through the action of the adjusting groove 89 and the positioning pin 87, so as to conveniently adjust the position of the blade clamp 84, so as to adapt to different outer diameter rubber tubes for stripping. When the adjustment is completed, the adjusting rod 8123 is pulled out, and the clamping block 8121 is re-engaged with the clamping groove 821 under the action of the spiral spring 8122, so as to limit the rotation of the adjusting hole column 812 inside the rotating ring 82, so as to fix the blade clamp 84, and ensure the stability of the blade clamp 84 during cutting, effectively ensuring the cutting precision.

[0048] By adjusting the fixing mechanism 5 and the cutting assembly 8, the device can adapt to different specifications of rubber tubes for stripping work, effectively increasing the use range of the device.

[0052] During the cutting process, the cutting assembly 8 is driven to step by the stepping motor 11. The stepping motor 11 drives the stepping screw 10 to rotate through the transmission assembly 12. When the stepping screw 10 rotates, the top sliding plate 7 slides on the top of the cantilever frame 3, thereby achieving the effect of automatic feeding, avoiding the trouble of manual pushing, improving the automation degree of rubber tube stripping, and effectively improving the stripping efficiency.
