A threaded rod 503 is installed on the other side of the tire positioning wheel 5 and the cutting disc 4. When the cutting machine is in use, the waste tire is placed outside the tire positioning wheel 5. The tire positioning wheel 5 rotates, which drives the waste tire to rotate and perform the cutting work.

[0025] A movable seat 301 is installed below the front limiting roller 3. Movable wheels 302 are provided on both sides of the movable seat 301. The movable wheels 302 are embedded in the outside of the device bracket 1 and rotatably connected to the device bracket 1. An electric cylinder is installed below the movable seat 301, and the two ends of the electric cylinder are respectively fixedly connected to the device bracket 1. The front limiting roller 3 can limit the front part of the tire. In conjunction with the side drive rollers 2 on both sides, the retraction of the electric cylinder adjusts the front limiting roller 3. The two ends of the side drive roller 2 are rotatably connected to the device bracket 1 through bearing seats. A motor 201 is installed at one end of the side drive roller 2. The motor shaft of the motor 201 is fixedly connected to the side drive roller 2 through a coupling. After the waste tire is fixed, the cutting disc 4 performs the cutting work. By continuously adjusting the electric cylinder, the front limiting roller 3 is driven to push the waste tire, which can adjust the cutting position of the tire. The cutting of the top and strips is automated, the structure is stable, and thus the tire cutting efficiency can be improved.

[0026] A first bushing 407 is installed at the rear end of the cutting disc 4. A rotating shaft is installed inside the first bushing 407, and a speed regulator 403 is installed at the rear end of the first bushing 407. A servo motor 404 is installed on one side of the speed regulator 403. The servo motor 404 is connected to the rotating shaft through the speed regulator 403.

[0027] Specifically, when using the tire cutting machine, the waste tire is placed outside the tire positioning wheel 5. The rotation of the tire positioning wheel 5 drives the waste tire to rotate and perform the cutting work. The front limit roller 3 can limit the front of the tire. In conjunction with the side drive rollers 2 on both sides, the retracting electric cylinder adjusts the front limit roller 3 to fix the waste tire. After that, the cutting disc 4 performs the cutting work. By continuously adjusting the electric cylinder, the front limit roller 3 is driven to push the waste tire, which can adjust the cutting position of the tire. The cutting of the top and the cutting of the tire are automated. The structure is stable, thereby improving the tire cutting efficiency.

[0028] To address the issue that existing tire top cutting and stripping machines cannot adapt to different sizes of waste tires during actual use, thus affecting work efficiency, please refer to... Figure 1 - Figure 5 This embodiment provides the following technical solution:

[0029] The rear end of the tire positioning wheel 5 is equipped with a second bushing 504, and the middle of the movable plate 401 is equipped with a hinge shaft. The two ends of the movable plate 401 are fixedly connected to the first bushing 407 and the second bushing 504 respectively. The cutting disc 4 is limited by the movable plate 401 and its angle is adjusted, which drives the cutting disc 4 to move, so that the position of the cutting disc 4 is stable to adapt to the working environment and conditions. The structure is simple and easy to use.

[0030] A fixing plate 402 is installed on one side of the first bushing 407. The fixing plate 402 has an integrally formed limiting groove 405 inside. Fastening bolts 406 are provided at the upper and lower ends of the limiting groove 405. The upper end of the threaded rod 503 passes through the limiting groove 405 and is fixedly connected to the fixing plate 402 by the fastening bolts 406. Before the cutting machine is used, the fastening bolts 406 can be adjusted according to the size of the waste tire to change the position of the fastening bolts 406 and the fixing plate 402 on the threaded rod 503.

[0031] The second bushing 504 has a rotating shaft installed inside. A reducer 501 is installed at the rear end of the second bushing 504. A drive motor 502 is installed below the reducer 501. The drive motor 502 is connected to the reducer 501 via a synchronous belt. The reducer 501 is connected to the rotating shaft. The drive motor 502 drives the reducer 501 to rotate the tire positioning wheel 5, thereby adjusting the top position of the tire.

[0032] Specifically, before using the cutting machine, the fastening bolts 406 can be adjusted according to the size of the waste tires. This changes the position of the fastening bolts 406 and the fixing plate 402 on the threaded rod 503. The cutting disc 4 is limited by the movable plate 401, allowing for angle adjustment and movement of the cutting disc 4. This stabilizes the position of the cutting disc 4, adapting to the working environment and conditions. The machine has a simple structure, is easy to use, and allows for adaptive adjustment to achieve the best cutting effect. The diverse adjustments improve processing efficiency.

[0033] Working principle: During use, the fastening bolt 406 is adjusted according to the size of the waste tire, changing the position of the fastening bolt 406 and the fixing plate 402 on the threaded rod 503. The cutting disc 4 is limited by the movable plate 401, and the angle is adjusted, driving the cutting disc 4 to move, so that the position of the cutting disc 4 is stable to adapt to the working environment and conditions. The structure is simple, easy to use, and adaptable to achieve the best cutting effect. Diverse adjustments improve processing efficiency. After the waste tire is placed outside the tire positioning wheel 5, the rotation of the tire positioning wheel 5 can drive the waste tire to rotate for cutting. The front limit roller 3 can limit the front of the tire. With the cooperation of the side drive rollers 2 on both sides, the retracting electric cylinder adjusts the front limit roller 3 to fix the waste tire. After that, the cutting disc 4 performs the cutting work. By continuously adjusting the electric cylinder, the front limit roller 3 pushes the waste tire, which can adjust the cutting position of the tire. The cutting of the top and strips is automated. The structure and position are stable, thereby improving the tire cutting efficiency.
