[0027] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] This embodiment provides a device for crushing and recycling waste materials used in rubber production, such as... Figure 1-6 As shown, the device includes a crushing assembly 1, which includes a housing 11, an adjustment groove 12, a first rotating shaft 13, a second rotating shaft 14, a crushing roller 15, a limiting frame 16, a U-shaped adjusting plate 17, a limiting ring 18, an adjusting screw 19, an adjusting screw hole 20, a first synchronous motor 21, and a second synchronous motor 22.

[0029] The casing 11 has adjustment slots 12 on both front sides. A first rotating shaft 13 is slidably connected to the inner wall of each adjustment slot 12. A second rotating shaft 14 passes through the rear side of the casing 11. Crushing rollers 15 are fixedly connected to the middle of the outer walls of both the first and second rotating shafts 13. Limiting frames 16 are fixedly connected to the outer sides of both sides of the casing 11 near the adjustment slots 12. U-shaped adjusting plates 17 are slidably connected to the inner walls of the two limiting frames 16. The two ends of the first rotating shaft 13 pass through the rear sides of the inner walls of the U-shaped adjusting plates 17. A limiting ring 18 is fixedly connected to the upper front surface of the casing 11. An adjusting screw 19 is rotatably connected to the inner wall of the limiting ring 18. The middle of the front surface of the U-shaped adjusting plate 17... An adjusting screw hole 20 is provided at the center. The outer side wall of the adjusting screw 19 is threaded to the inner side wall of the adjusting screw hole 20. A first synchronous motor 21 is fixedly connected to the rear side of one side of the U-shaped adjusting plate 17. One end of the first rotating shaft 13 is fixedly connected to the output end of the first synchronous motor 21. A second synchronous motor 22 is fixedly connected to the outer side of one side of the housing 11 near the second rotating shaft 14. One end of the second rotating shaft 14 is fixedly connected to the output end of the second synchronous motor 22. The first synchronous motor 21 drives the first rotating shaft 13 to rotate, and the second synchronous motor 22 drives the second rotating shaft 14 to rotate, thereby causing the two crushing rollers 15 to rotate relative to each other, so that the rubber waste is crushed under the squeezing and shearing action of the two crushing rollers 15.

[0030] In one embodiment, the inner top and bottom walls of the two limiting frames 16 are provided with limiting grooves 23, and the upper and lower surfaces of the U-shaped adjusting plate 17 are fixedly connected with limiting strips 24. The outer side wall of the limiting strip 24 is slidably connected to the inner side wall of the limiting groove 23. By sliding the limiting strip 24 on the U-shaped adjusting plate 17 inside the limiting groove 23, the limiting strip 24 is limited, thereby increasing the stability of the movement of the U-shaped adjusting plate 17.

[0031] In one embodiment, specifically, scales 25 are provided on the upper parts of both sides of the U-shaped adjusting plate 17, and an adjusting turntable 26 is fixedly connected to the front part of the outer side wall of the adjusting screw 19, so that the adjusting screw 19 can be rotated by adjusting the turntable 26.

[0032] In one embodiment, specifically, an annular limiting groove 27 is provided in the middle of the inner sidewall of the limiting ring 18, and an annular limiting ring 28 is provided in the rear of the outer sidewall of the adjusting screw 19. The outer sidewall of the annular limiting ring 28 is rotatably connected to the inner sidewall of the annular limiting groove 27. By rotating the annular limiting ring 28 on the adjusting screw 19 inside the annular limiting groove 27, the annular limiting ring 28 is limited, thereby preventing the adjusting screw 19 from slipping out of the limiting ring 18.

[0033] In one embodiment, specifically, inclined feed guide plates 29 are fixedly connected to the upper part of the front and rear sides of the inner sidewall of the housing 11 near the crushing roller 15, and inclined discharge guide plates 30 are fixedly connected to the lower part of the rear sides of the inner sidewall of the housing 11 near the crushing roller 15. The inclined discharge guide plates 30 facilitate the flow of crushed rubber particles to the highest point of the inclined screen 31, so that the rubber particles move from high to low along the inclined screen 31 for screening.

[0034] In one embodiment, specifically, inclined screens 31 are fixedly connected to the lower part of the inclined discharge guide plate 30 on both sides of the inner sidewall of the housing 11. A vibrator 32 is fixedly connected to the center of the lower surface of the inclined screen 31. A first discharge port 33 is provided on the rear surface of the housing 11 near the upper part of the inclined screen 31. The inclined screen 31 is vibrated by the vibrator 32, which facilitates the screening of the crushed rubber particles.

[0035] In one embodiment, a feed hopper 34 is fixedly connected to the top of the housing 11, and a discharge hopper 35 is fixedly connected to the bottom of the housing 11. A second discharge port 36 is provided at the bottom of the discharge hopper 35, through which rubber particles that have fallen after being screened by the inclined screen 31 can be discharged.

[0036] In one embodiment, a support frame 37 is fixedly connected to the bottom of the outer side wall of the housing 11. The support frame 37 supports the housing 11, thereby increasing the stability of the entire device.

[0037] The working process of the rubber production waste crushing and recycling device in this embodiment is as follows: First, observe the scale 25 to understand the current position of the U-shaped adjustment plate 17 and the distance between the crushing rollers 15 on the first rotating shaft 13 and the second rotating shaft 14. By rotating the adjustment turntable 26, the adjustment screw 19 is rotated, thereby driving the U-shaped adjustment plate 17 to move back and forth, which in turn drives the first rotating shaft 13 to move back and forth. By moving the first rotating shaft 13 back and forth, the crushing rollers 15 on the first rotating shaft 13 are moved back and forth, which makes it easy to adjust the distance between the two crushing rollers 15 according to actual needs, so as to adapt to rubber waste of different sizes. After adjusting the distance between the two crushing rollers 15, the rubber production waste is poured into the feed hopper 34. The waste enters the machine casing 11 through the feed hopper 34. Under the guidance of the inclined feed guide plate 29, the waste falls smoothly between the two crushing rollers 15. The first synchronous motor 21 and the second synchronous motor 22 are started. The first synchronous motor 21 drives the first rotating shaft 13 to rotate, and the second synchronous motor 22 drives the second rotating shaft 14 to rotate, thereby causing the two crushing rollers 15 to rotate relative to each other. The waste material is crushed under the squeezing and shearing action of the two crushing rollers 15. The crushed waste material falls to the highest point of the inclined screen 31 under the guidance of the inclined discharge guide plate 30. The vibrator 32 is activated, and the vibrator 32 causes the inclined screen 31 to vibrate, screening the crushed waste material. Waste material with the required particle size falls into the discharge hopper 35 through the inclined screen 31 and is finally discharged from the second discharge port 36. Waste material with larger particles that do not meet the requirements moves downward under the action of the inclined screen 31 and is discharged from the first discharge port 33 for further crushing.

[0038] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this innovative technical solution.
