Further, in the shredding operation, the gap between the shredding gears needs to be cleaned comprehensively to prevent the existence of a blind area in the fixed position, at this time, the equipment needs to automatically reciprocate the material shifting gear 28, first, the control cabinet starts the first servo motor 5 at both sides of the driving rod 21, the first servo motor 5 drives the rotating cylinder 9 to rotate, thereby driving the half-toothed screw rod 18 and the fixed composite bearing 14 to move inward, pushing the driving rod 21 and the material shifting gear 28 to move to the gap side, the switch disc 19 is arranged at the junction of the toothless section and the toothed section of the half-toothed screw rod 18, when the material shifting gear 28 moves to the vicinity of the inner limit preset position, the switch disc 19 moves to the position in contact with the steering switch 12 with the half-toothed screw rod 18, the steering switch 12 is installed on the disc 11 at the front end of the rotating cylinder 9, the steering switch 12 is a mechanical trigger device, when the switch disc 19 contacts and presses the steering switch 12, the steering electrical signal is triggered, the electrical signal is transmitted to the control cabinet through the second connecting line 10, after the control cabinet receives the steering signal, immediately changes the instruction, so that the first servo motor 5 currently working reverses, for example, from counterclockwise to clockwise rotation, at the same time, the control cabinet controls another first servo motor 5 arranged at the back side of the driving rod 21 to also reverse the running direction synchronously; The first servo motor 5, which initially pulls inward on the front side of the drive lever 21, changes to pushing outward, while the first servo motor 5 on the rear side of the drive lever 21 changes to pulling inward. Driven by the first servo motors 5 on both sides, the drive lever 21 begins to move in opposite directions. At the same time, the feeding gear 28 also moves in the opposite direction within the gap. When the feeding gear 28 moves to near the limit position on the rear side of the drive lever 21, the switch disk 19 on the half-tooth screw 18 triggers the rear direction switch 12. The direction switch 12 sends a signal to the control console, which then controls the two first servo motors 5 to reverse again. This cycle repeats, enabling the feeding gear 28 to achieve automatic and periodic reciprocating motion within the gap width of the two shredding gears. At the same time, the cleaning range of the feeding gear 28 also covers the full width of the gap between the shredding gears, effectively removing any residue or newly appearing entanglement in the gap. This enhances the equipment's self-cleaning ability and anti-clogging reliability, making it suitable for processing tire materials with high viscosity or high fiber content. It also improves the intelligence level and stability of the equipment's continuous operation.

[0027] Please see Figure 1 , Figure 2 , Figure 3 , Figure 8 , Figure 9 , Figure 12 and Figure 16 An embodiment of the present invention provides a tire shredding roller structure, wherein the auxiliary rod 40 is connected to the sixth connecting hole 37 of the second servo motor 36, the front side of the outer wall of the moving block 29 is provided with a screw hole 30 and a fourth connecting hole 31, the side side of the outer wall of the moving block 29 is provided with a fifth connecting hole 32, a long screw 34 is provided in the screw hole 30 of the moving block 29, one end of the long screw 34 is connected to the second servo motor 36, and the other end of the long screw 34 is connected to a limiting block 35, the limiting block 35 is used to prevent the moving block 29 from falling off, the side side of the outer wall of the second servo motor 36 is provided with a second fixing plate 38, the side side of the outer wall of the second fixing plate 38 is provided with a second bolt 39, the second bolt 39 passes through the second fixing plate 38 and the side plate 41 to fix the second servo motor 36; Further, when processing different size types of tires, the device optimizes the cleaning intensity by adjusting the engagement depth between the shredding gear and the poking gear 28. When processing small tires, the size of the fragments generated by the shredding gear is relatively small, and it is easy to embed between the teeth of the shredding gear or accumulate in the deep gap. If the engagement between the poking gear 28 and the shredding gear is too shallow, the cleaning effect will only be on the surface, and the deep accumulation cannot be effectively removed, which will cause the gap to be blocked over a long period of time, and the shredding efficiency will decrease. Therefore, the device first adjusts the poking gear 28 to a deeper engagement position. The control panel simultaneously starts the second servo motor 36 installed on the two side plates 41. The output shaft of the second servo motor 36 drives the connected long screw 34 to rotate counterclockwise. The long screw 34 is threadedly engaged with the screw hole 30 of the moving block 29, and the outer wall side of the moving block 29 is in close contact with the side plate 41. Therefore, the moving block 29 converts the rotary motion into linear motion along the long screw 34. The moving block 29 is driven by the long screw 34 to stably translate along the auxiliary rod 40 in the axial direction. The auxiliary rod 40 ensures that the moving block 29 moves stably and does not deflect. The bottom end of the moving block 29 is fixedly connected to the outer wall top end of the limiting ring 33. The limiting ring 33 is sleeved on the driving shaft 25 through the sliding bearing on the inner wall, realizing relative rotation and axial fixation. Therefore, the axial movement of the moving block 29 directly drives the limiting ring 33 to move, and in turn drives the driving shaft 25, the driving rod 21 and the poking gear 28 to move into the interior of the shredding gear gap. After the movement is completed, the long screw is screwed into the fifth connecting hole 32 and the seventh connecting hole 42 to fix the moving block 29 on the side plate 41. When processing large tires, the tire fragments have large volume and high hardness. At this time, in order to avoid excessive interference or excessive resistance between the poking gear 28 and the large fragments, the engagement depth needs to be appropriately adjusted to be shallow. The control panel controls the second servo motor 36 to rotate clockwise through the first connecting line 8, drives the moving block 29 to drive the driving shaft 25 to move away from the shredding gear, thereby increasing the operating gap between the poking gear 28 and the working tooth surface of the shredding gear. This makes the same device be able to efficiently process a wide range of materials from small car tires to large engineering tires, avoiding overloading and wear of the poking gear 28 caused by excessive engagement, or ineffective cleaning caused by shallow engagement, thereby prolonging the service life of the gear.

[0028] Working principle: The tire is conveyed to the feeding gear 44 by the feeding roller 43, guided into the first shredding gear 45 and the second shredding gear 46 for shredding and cutting by the feeding gear 44, and the driving motor 27 drives the driving shaft 25 to rotate. The driving rod 21 is synchronously rotated through the engagement of the clamping block 24 and the clamping groove 23, driving the poking gear 28 to rotate. The poking gear 28 scrapes the tire fragments remaining in the gap between the shredding gears to prevent material entanglement and blockage. When the device adjusts the position of the poking gear 28, the console drives the rotating cylinder 9 to rotate through the first servo motor 5, drives the half tooth screw 18 to move axially through the screw thread, further drives the composite bearing 14 and the driving rod 21 to slide along the driving shaft 25, realizes the transverse position adjustment of the poking gear 28 in the shredding gap, and the position adjustment can be dynamically performed when the device is running or can be implemented in the stop state; When the device needs to be automatically cleaned back and forth, the half tooth screw 18 is provided with a switch disc 19, the switch disc 19 triggers the steering switch 12 when moving to the limit position, the steering switch 12 transmits the reverse signal to the console, the console controls the first servo motor 5 to reverse, so that the poking gear 28 reciprocates in the gap and cleans the residues comprehensively; For different specifications of tires, the second servo motor 36 drives the long screw 34 to rotate, thereby driving the moving block 29 to move axially along the auxiliary rod 40, the moving block 29 drives the driving shaft 25 through the limiting ring 33, thereby adjusting the axial position of the driving rod 21 and the poking gear 28 as a whole, adjusting the biting depth of the poking gear 28 and the shredding gear, and adapting to the cleaning requirements of different materials, thereby improving the adaptability and operation reliability of the device.
