[0021] The present invention will be described in detail with reference to the accompanying drawings in the embodiments of the present invention.

[0022] A vehicle tire recycling and processing device includes a rotating part 101, a plurality of slots 102 formed on the rotating part 101, a plurality of feeding plates 103 fixedly connected to the inner wall of the rotating part 101, a crushing box 201 disposed inside the rotating part 101, a guide plate 202 fixedly connected to the crushing box 201, the guide plate 202 being inclined, a crushing mechanism disposed inside the crushing box 201, and a driving mechanism connected below the rotating part 101.

[0023] See Figures 1-5 ,

[0024] When using the processing device, the operator first places the tire after removing the steel wires into the crushing box 201, and then uses the crushing mechanism in the crushing box 201 to crush the tire. The crushed tire fragments fall directly into the rotating part 101. Since the rotating part 101 has multiple slots 102, the tire fragments can be discharged through the multiple slots 102. The multiple slots 102 play a role in screening the tire fragments. Tire fragments that meet the size requirements can be discharged directly through the multiple slots 102, while tire fragments that do not meet the size requirements cannot be discharged through the multiple slots 102 and are isolated in the rotating part 101.

[0025] When the tire is being crushed, the operator controls the drive mechanism to drive the rotating part 101 to rotate, so that the tire fragments can roll inside the rotating part 101. This promotes the movement of the tire fragments inside the rotating part 101, prevents the tire fragments from accumulating, and speeds up the discharge of qualified tire fragments.

[0026] When the rotating part 101 rotates, the isolated tire fragments can be blocked by the feeding plate 103 and then move upward with the feeding plate 103. When the feeding plate 103 is in a downward tilting state, the tire fragments can automatically slide down along the feeding plate 103 and then automatically slide back down into the crushing box 201 along the guide plate 202. The crushing mechanism then performs secondary crushing on the tire fragments until the size meets the qualified standard. The guide plate 202 serves to guide the tire fragments, enabling the moving tire fragments to accurately return to the crushing box 201 without the need for workers to collect and put them back into the crushing box 201, saving labor and time. At the same time, the structure of the rotating part 101 can also be used to simultaneously screen the tire fragments.

[0027] The rotating section 101 is driven to rotate by a drive mechanism, and multiple evenly distributed grooves 102 on its inner wall form a continuous screening channel. When tire fragments enter the rotating section 101, fragments of the acceptable size ≤50mm are quickly discharged through the grooves 102, while larger fragments >50mm are isolated inside the rotating section 101. This dynamic screening mechanism avoids the problem of easy clogging of traditional static screens, thus improving screening efficiency. Through innovative combination of mechanical structures, this device solves the technical pain points of traditional tire shredding equipment, such as low screening efficiency, high energy consumption of circulating crushing, and frequent manual intervention. Its overall processing cost is lower than similar equipment, and the rubber powder output rate is higher, making it particularly suitable for processing engineering tire recycling scenarios with a high steel cord content.

[0028] The surface of the guide plate 202 has multiple through grooves 203.

[0029] See Figure 1 ,

[0030] When tire fragments fall back onto the guide plate 202, the multiple through grooves 203 on the surface of the guide plate 202 can perform a second screening function on the tire fragments, thereby reducing the amount of crushing, further reducing the workload of the crushing mechanism, achieving energy saving, and avoiding ineffective crushing.

[0031] The guide plate 202 is inclined at a 30° angle to the horizontal plane, which, together with the longitudinal extension direction of the through groove 203, forms a sliding screening effect.

[0032] The crushing mechanism includes two crushing rollers 205, both of which are rotatably connected inside the crushing box 201. Both crushing rollers 205 are provided with interlocking teeth, and both crushing rollers 205 are provided with multiple interlocking teeth 206 on their surfaces. The tops of the multiple interlocking teeth 206 on the two crushing rollers 205 are facing each other.

[0033] See Figures 3-4 ,

[0034] When the recycled tires are put into the crushing box 201, the two crushing rollers 205 are controlled to rotate in turn, and the shearing force generated by the interlocking teeth on the two crushing rollers 205 is used to shear and crush the tires, thereby realizing the crushing function of the punctured tires.

[0035] Multiple biting teeth 206 can improve the biting ability of the tire, making it easier to shear and crush the tire, preventing the tire from slipping above the two crushing rollers 205 and thus avoiding wasted time and improving the crushing efficiency of the tire.

[0036] The top of the 206 engagement tooth features a tapered protrusion design, and the relative tooth surface spacing gradually decreases from top to bottom. When the tire engages with the teeth, the tapered tooth tip enhances the engagement force through a self-locking effect, preventing slippage caused by tire elastic rebound.

[0037] A first motor 204 is fixedly connected to the crushing box 201. One of the crushing rollers 205 is fixedly connected to the output shaft of the first motor 204. Gears 207 are fixedly connected to both crushing rollers 205, and the two gears 207 mesh for transmission.

[0038] See Figure 4 ,

[0039] The first motor 204 drives one of the crushing rollers 205 to rotate, and with the cooperation of the two gears 207, it can drive the two crushing rollers 205 to rotate relative to each other, thereby realizing the function of crushing tires.

[0040] The drive mechanism includes a bracket 301, on which two conveying rollers 302 are rotatably connected. A second motor 204 is fixedly connected to the bracket 301, and one of the conveying rollers 302 is fixedly connected to the output shaft of the second motor 204.

[0041] See Figures 5-6 ,

[0042] When it is necessary to control the rotation of the rotating part 101, the operator drives one of the conveying rollers 302 to rotate by controlling the second motor 204. Then, with the cooperation of the other conveying roller 302, the rotating part 101 is driven to rotate. The two conveying rollers 302 cooperate to support and limit the rotating part 101, so as to prevent the rotating part 101 from deviating.

[0043] Two limiting posts 404 are fixedly connected to the bracket 301, and a vibrating frame 401 is slidably connected between the two limiting posts 404. A cleaning blade 402 is fixedly connected between the vibrating frame 401.

[0044] See Figure 3 ,

[0045] While crushing and screening tire fragments, the vibrating frame 401 is controlled to slide back and forth on the two limiting posts 404, which in turn causes the cleaning blade 402 to slide up and down. As the rotating part 101 rotates, the cleaning blade 402 moves upward and passes through the trough 102, thereby clearing the trough 102 and removing the tire fragments stuck in the trough 102, thus preventing the trough 102 from becoming blocked and preventing the tire fragments from being discharged.

[0046] The frequency of the reciprocating sliding of the cleaning blade 402 is matched with the rotation speed of the rotating part 101. Thus, when the rotating part 101 rotates, the cleaning blade 402 can sequentially unclog and clean multiple grooves 102, promoting the rapid discharge of tire debris.

[0047] The cleaning blade 402, through the high-frequency reciprocating sliding of the vibrating frame 401 on the limiting post 404, generates a pulse-like impact force on the drain 102. When tire fragments become stuck in the drain gap, the cutting edge of the cleaning blade 402 instantly breaks the blockage through a dynamic shearing-compression composite action, resulting in better unblocking efficiency than traditional static unblocking.

[0048] The cleaning blade 402 is coated with a tungsten carbide-diamond composite coating, and the cutting edge is designed with a serrated microstructure. During reciprocating motion, the coating can effectively remove adhering adhesive powder, preventing the cutting edge from clogging.

[0049] One of the conveyor rollers 302 is fixedly connected to a swing arm 501, and the vibration frame 401 is fixedly connected to a contact rod 502. Both limit posts 404 are fitted with springs 405, which are located between the vibration frame 401 and the support 301.

[0050] See Figure 7 ,

[0051] During the process of conveying the rotating part 101 by rotating the conveyor roller 302, one of the conveyor rollers 302 drives the swing rod 501 to rotate around the axis of the conveyor roller 302. When the protruding end of the swing rod 501 contacts the contact rod 502, the swing rod 501 presses down on the contact rod 502, and at the same time, the contact rod 502 drives the vibration frame 401 to move downward. At this time, both springs 405 are in a compressed state. When the swing rod 501 disengages from the contact rod 502, the vibration frame 401 automatically rises under the elastic action of the two springs 405, thereby realizing the reciprocating sliding function of the vibration frame 401.

[0052] The power generated by the rotation of the conveyor roller 302 simultaneously enables the vibrating frame 401 to slide up and down, thereby matching the frequency of the reciprocating sliding of the cleaning blade 402 with the rotation speed of the rotating part 101.

[0053] By utilizing the residual kinetic energy of the conveyor roller 302, the rotational kinetic energy is converted into the reciprocating mechanical energy of the vibrating frame 401 through the cam-type contact between the swing arm 501 and the contact rod 502. This design reduces energy consumption and eliminates the need for additional lubrication and maintenance.

[0054] A sieve plate 403 is fixedly connected to the vibrating frame 401, and multiple sieve holes are opened on the sieve plate 403.

[0055] See Figure 7 ,

[0056] The sieve plate 403 is used to further screen the discharged tire fragments. After being energized, the sieve plate 403 generates magnetism, which can adsorb the residual crushed steel wires in the tire fragments, thereby further improving the overall quality of the tire fragments and preventing steel wire fragments from being mixed into the rubber.

[0057] The sieve plate 403 uses a pulsed electromagnet array, and the magnetic field strength is controlled by a PLC. When tire fragments pass through the sieve holes, the magnetic field generates a directional attraction force on the ferromagnetic material, so that steel wires with a particle size greater than 3mm are completely captured.

[0058] The sieve plate 403 generates mechanical vibration through the reciprocating motion of the vibrating frame 401, which, combined with the alternating effect of the electromagnetic field, forms a composite unblocking effect.

[0059] Both conveyor rollers 302 have friction textures on their surfaces.

[0060] See Figure 7 ,

[0061] The friction texture is used to increase the friction between the surfaces of the two conveyor rollers 302 and the surface of the rotating part 101, thereby ensuring transmission efficiency and avoiding slippage.

[0062] A method for processing tires using a processing device, the method comprising the following steps:

[0063] Step 1: The pre-treated tire block enters the crushing box 201, where it is sheared and crushed by two opposing rotating crushing rollers 205. The crushing rollers have staggered conical meshing teeth 206 distributed on their surfaces.

[0064] Step 2: The crushed rubber blocks are conveyed to the screening section by the conveyor roller 302, while simultaneously driving the swing arm 501 to rotate. When the protruding end of the swing arm contacts the contact rod 502, it drives the cleaning blade 402 to penetrate the trough 102. The spring 405 provides elastic restoring force, forming a high-frequency reciprocating motion.

[0065] Step 3: Large tire blocks are intercepted by the guide plate and slide into the secondary crushing zone, while fine particles directly enter the subsequent crushing process;

[0066] Step 4: The glue block enters the magnetic sieve plate 403 through the trough 102, where the built-in pulse electromagnet array dynamically adsorbs the residual steel wire debris.

[0067] Step 5: Finally, the adhesive powder enters the cyclone dust collector through the negative pressure air extraction channel.
