[0035] Furthermore, a groove 24 is provided under the cross plate 3, and a coil spring 25 and a limit block 23 are installed in sequence inside the groove 24 from the inside to the outside. The limit block 23 is inclined on one side close to the center of the cross plate 3, and a limit hole 26 corresponding to the limit block 23 is provided under the connecting member 4. Both the limit block 23 and the mounting seat 8 are magnetic, and the limit block 23 and the mounting seat 8 repel each other.

[0036] A movable groove 19 is provided inside the support frame 5, and a mounting block 20 is slidably inserted inside the movable groove 19.

[0037] The pushing structure includes a fixed block 21 and a push rod 22. The fixed block 21 is fixedly sleeved outside the center of the horizontal plate 3. One end of the push rod 22 is rotatably connected to the fixed block 21, and the other end of the push rod 22 is rotatably connected to the mounting block 20.

[0038] Working principle: Put the rubber material with arc-shaped surface into the rubber crusher housing 1 through the feeding port 2, and the material falls above the crushing blade 30. In the initial state, the support frame 5 is vertical, and the motor 17 is connected to the external power supply. The motor 17 drives the threaded rod 16 to rotate. Since the threaded rod 16 and the slider 14 are threadedly connected, the threaded rod 16 can drive the slider 14 to rise and fall inside the slide 15. When the slider 14 moves downward, it drives the cross plate 3 to move synchronously, and the cross plate 3 drives the gear 12 to move synchronously. Since the gear 12 is meshed with the rack 13, the rack 13 can drive the gear 12 to rotate, so that the support frame 5 can be rotated to a horizontal state. At this time, the No. 1 poking needle 6 and the No. 2 poking needle 18 are arranged vertically, and the No. 1 poking needle 6 and the No. 2 poking needle 18 can penetrate into the interior of the rubber material. For some rubber materials filled with gas, the internal gas can be released, and the material can be pushed toward the direction of the crushing blade 30. Under the action of the rotating shaft 29, it is convenient for the crushing blade 30 to crush the material.

[0039] The horizontal plate 3 drives the support block 9 to move synchronously during the downward movement. At this time, the guide block 28 can move along the groove body 27, thereby driving the support block 9 to move left and right during the downward movement, so that the support frame 5, the No. 1 poking needle 6 and the No. 2 poking needle 18 move synchronously, which can increase the piercing range of the No. 1 poking needle 6 and the No. 2 poking needle 18.

[0040] When the support block 9 stops moving, the cross plate 3 continues to move downward. At this time, under the action of the connecting rod 10, the connecting rod 10 drives the two groups of connecting parts 4 to move away from each other outside the cross plate 3 through the mounting seat 8, thereby driving the two groups of support frames 5 to move away from each other. At this time, the return spring 11 is deformed by the force, and the support frame 5 drives the No. 1 poking pin 6 and the No. 2 poking pin 18 to move synchronously to tear the material.

[0041] Furthermore, under the action of the fixing block 21, when the two groups of support frames 5 move away from each other, they can drive the two groups of push rods 22 to rotate, and the angle between the two groups of push rods 22 gradually increases. The two groups of push rods 22 can pull the mounting block 20 to slide inside the movable groove 19. At this time, the mounting block 20 drives the No. 2 poking pin 18 to move away from the No. 1 poking pin 6, which is conducive to further improving the tearing effect.

[0042] When the connecting member 4 moves to the position of the limit block 23, the connecting member 4 squeezes the limit block 23 into the inside of the groove 24. At this time, the coil spring 25 is deformed by the force. When the position of the limit hole 26 and the limit block 23 corresponds to each other, the coil spring 25 drives the limit block 23 to be inserted into the inside of the limit hole 26. At this time, the limit block 23 is vertically arranged with the mounting seat 8. When the cross plate 3 moves upward, the rack 13 drives the gear 12 to rotate. At this time, the limit block 23 and the mounting seat 8 are in the same vertical position. Since the limit block 23 and the mounting seat 8 are both magnetic and repel each other, the mounting seat 8 can push the limit block 23 to the inside of the groove 24 through magnetic force, so that the limit block 23 is disengaged from the limit hole 26. Under the action of the reset spring 11, the two groups of mounting seats 8 can be driven close to each other, so that the device can be used again.
