[0031] Please refer to Figures 1 to 4 The present embodiment is an automatic cutting device for waste tires, which comprises:

[0032] The cutting assembly comprises a cutting machine body 11, a fixed frame 15 and a conveyor belt 17. The fixed frame 15 is fixedly connected to one side of the cutting machine body 11, and the conveyor belt 17 is installed inside the fixed frame 15. The cutting assembly further comprises a base frame 12, a discharge port 13, an inlet port 14 and a support frame 16. The base frame 12 is fixed to the lower surface of the cutting machine body 11. The discharge port 13 is arranged in the middle of one side of the cutting machine body 11. The inlet port 14 is arranged in the middle of the other side of the cutting machine body 11. The support frame 16 is fixed to the lower surface of the fixed frame 15.

[0033] The cutting machine body 11 is the core part of the whole device, which is used to perform the cutting operation of the tire strip, and can efficiently cut the tire strip into blocks. The conveyor belt 17 is used to convey the tire strip to be cut. The existence of the conveyor belt 17 enables the tire strip to pass through the cutting area continuously and stably, thereby improving the cutting efficiency.

[0034] The flattening assembly comprises a limiting groove 21, a fixed block 22, a fixed frame 23, a threaded rod 24, a lifting frame 25, a sliding block 26 and a compression roller 28. The limiting groove 21 is arranged on the inner wall of the fixed frame 15. The two fixed blocks 22 are fixed on the outer surface of the fixed frame 15. The two fixed frames 23 are fixed on the top center of the two fixed blocks 22. The threaded rod 24 is screwed through the top center of the fixed frame 23. The lifting frame 25 is fixedly connected to the bottom surface of the threaded rod 24. The sliding block 26 is fixed on the two sides of the lifting frame 25. The compression roller 28 is rotatably installed inside the lifting frame 25.

[0035] The limiting groove 21 is used to limit the movement range of the fixed block 22 and the fixed frame 23, so as to ensure their stability during lifting. The compression roller 28 is used to flatten the tire strip to be cut. The existence of the compression roller 28 can improve the cutting accuracy and efficiency. The sliding block 26 is used in cooperation with the limiting groove 21 to ensure the stability of the lifting frame 25 during movement.

[0036] The flattening assembly further comprises a handle 241 and a bearing 242. The handle 241 is fixedly connected to the top surface of the threaded rod 24. The bearing 242 is penetrated through the bottom end of the threaded rod 24. The mounting hole 27 is arranged in the inner center of the lifting frame 25. The sliding block 26 is penetrated through the inner part of the limiting groove 21. The compression roller 28 is rotatably installed inside the mounting hole 27.

[0037] The bearing 242 is used to reduce friction, so that the threaded rod 24 can rotate smoothly. The mounting hole 27 is used to install the compression roller 28. The compression roller 28 rotates inside the lifting frame 25 to flatten the tire strip to be cut. The sliding block 26 is used in cooperation with the limiting groove 21 to ensure the stability of the lifting frame 25 during movement.

[0038] Working principle:

[0039] When cutting the tire, the worker places the tire strip on the upper surface of the conveyor belt 17. According to the thickness of the tire, the worker holds the handle 241 and rotates the handle 241. The handle 241 drives the threaded rod 24 to rotate synchronously. Under the connection of the bearing 242, the lifting frame 25 moves up and down in the fixed frame 15, and the sliding block 26 moves in the limiting groove 21. When the threaded rod 24 moves downward, the lifting frame 25 also moves downward. The gap between the compression roller 28 and the conveyor belt 17 becomes smaller, which is suitable for thinner tire strips. When the threaded rod 24 moves upward, the lifting frame 25 also moves upward. The gap between the compression roller 28 and the conveyor belt 17 becomes larger, which is suitable for thicker tire strips. The applicability of the cutting equipment is improved.

[0040] This step not only improves the safety and efficiency of the operation, but also enhances the adaptability and flexibility of the equipment.

[0041] Please refer to Figures 1 to 4As shown in the figure; this embodiment is based on the above embodiment 1, further comprising:

[0042] The limiting assembly comprises a connecting frame 31, a spring 32 and a connecting plate 33, the connecting frame 31 is fixed to the inner wall of the two lifting frames 25, the spring 32 is fixed to the lower surface of the connecting frame 31, the connecting plate 33 is fixedly connected to the lower end of the spring 32, the lower surface of the connecting plate 33 is provided with a rotating groove 34, and a ball 35 is rotatably installed in the rotating groove 34;

[0043] The spring 32 tightly presses the connecting plate 33 against the tire strip by the elastic force, so that the tire strip does not move during cutting, thereby improving the cutting precision and efficiency, the ball 35 is rotatably installed in the rotating groove 34, the ball 35 can roll in the rotating groove 34, the friction between the tire strip and the connecting plate 33 is reduced, the tire strip is more easily conveyed into the cutting machine for cutting, the ball 35 contacts and rolls with the tire strip, which helps to reduce the friction resistance and improve the moving efficiency of the tire strip.

[0044] Working principle:

[0045] When the tire strip is on the upper surface of the conveying belt 17 and passes between the two compression rollers 28, it may be raised, the connecting frame 31 moves up and down with the lifting frame 25, and under the action of the elastic force of the spring 32, the spring 32 presses the connecting plate 33 downward, so that the connecting plate 33 tightly adheres to the tire strip, and the ball 35 rotates in the rotating groove 34, the tire strip contacts the ball 35, and the ball 35 rotates, so that the tire strip is moved into the cutting machine body 11;

[0046] This step effectively prevents the tire strip from being stuck or deviating from the track during conveying due to the lifting, so that the tire strip can smoothly move into the cutting machine body 11, thereby improving the cutting efficiency.

[0047] In the description of the present application, unless otherwise specified and limited, the terms "setting", "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrally connected, it can be mechanically connected, or it can be electrically connected, it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be the communication between two elements.
