[0024] Specifically, the top end of the moving block 8 is fixedly pressed against the first spring 9, and the other end of the first spring 9 is pressed against the top end of the fixed plate 2. The outer inner side of the cutting ring 6 is spirally connected with a pressing pin 7, which passes through the interior of the cutting ring 6 and is pressed against the top end of the rotating rod 5.

[0025] Furthermore, a rotating roller 20 is rotatably connected to the interior of the slitting machine 1 , and the top end of the rotating roller 20 is used to transport the tire leather 19 .

[0026] Furthermore, a reinforcing rib 26 is fixedly connected to the outer side of the slitting machine 1 , and the reinforcing rib 26 is used to support the support rod 10 fixedly connected to the top end. A third spring 25 is sleeved on the outer side of the support rod 10 .

[0027] It is worth noting that the other end of the third spring 25 is tightly supported by a cutter 24 , which slides upward under the reaction force of the third spring 25 , and the inner center position of the cutter 24 slides up and down on the outside of the support rod 10 .

[0028] It is worth noting that a motor 21 is fixedly connected to the outside of the slitting machine 1, and the output end of the motor 21 is rotatably connected to a rotating protrusion 22. The rotating protrusion 22 drives the connecting plate 23 to slide up and down, and the rear side of the connecting plate 23 is fixedly connected to the cutting knife 24 by bolts.

[0029] It is worth mentioning that the bottom end of the cutter 24 slides up and down on the top of the tire leather 19. The cutter 24 is used to cut the tire leather 19.

The "front, back, left and right" perspectives of the device are as follows: Figure 1 The direction shown in the figure is the reference.

[0031] Working principle:

[0032] The tire leather material 19 is first placed on the top of the rotating roller 20 inside the slitting machine 1, and the rotating roller 20 drives the tire leather material 19 to move toward the cutting knife 24. During the movement, the cutting ring 6 on the outside of the rotating rod 5 cuts the tire leather material 19. The cutting ring 6 is squeezed by the tire leather material 19 to drive the moving block 8 to squeeze the first spring 9 to slide upward inside the fixed plate 2. During the sliding process, the first spring 9 squeezes the moving block 8 to slide downward. The moving block 8 after being tightened fits the tire leather material 19 tightly. Then, when the width of the tire leather material 19 needs to be changed, it is only necessary to release the tightening pin 7 on the outside of the cutting ring 6, and the screw rod 12 inside the frame 11 drives the sliding block 13 to move. The tightening disc 18 rotates inside the rotating seat 14, and the tightening disc 18 is tightened against the cutting ring 6, driving the cutting ring 6 to slide on the outside of the rotating rod 5. After moving to the required position, the tightening pin 7 is rotated to achieve the connection between the cutting ring 6 and the rotating rod 5.

[0033] Then, after the slitting is completed, the roller 20 is rotated to move to the bottom end of the cutter 24, and the motor 21 drives the rotating protrusion 22 to rotate. The rotating protrusion 22 drives the cutter 24 fixedly connected to the connecting plate 23 to slide up and down on the tire leather 19 to cut the tire leather 19. In the process of sliding downward, the cutter 24 slides downward on the outside of the support rod 10, and the cutter 24 slides upward under the reaction force of the third spring 25.
