Description

Technical Field

[0001] This invention relates to the field of rubber waste treatment technology, specifically to a device for recycling and treating solid waste from rubber products. Background Technology

[0002] If waste rubber is not properly disposed of, it will occupy a large amount of land resources and may even pollute the soil and groundwater. Recycling can effectively reduce the pollution of these wastes to the environment, protect the ecological environment, and reduce the demand for new rubber raw materials, thus contributing to the sustainable use of resources and alleviating the pressure on the natural environment. In particular, with the rapid development of the automotive industry, the number of waste tires has been increasing year by year, putting enormous pressure on the environment.

[0003] CN118438572B discloses an environmentally friendly treatment device for the recycling of waste tire rubber. The problem raised in the background technology is that when processing waste tires, the steel wires are not effectively removed, resulting in a large number of steel wires remaining in the recycled rubber. This not only affects the quality of the rubber but also causes inconvenience to subsequent processing and use. If the steel wires and rubber are not effectively separated, some steel wires may enter the subsequent recycling process, posing a potential threat to the environment and the quality of recycled rubber, which is not conducive to the environmentally friendly treatment of waste tire rubber recycling.

[0004] In existing technologies, the recycling of waste rubber tires typically involves cutting off the tire sidewall, separating the steel wires in the sidewall and tread separately, and then proceeding with further processing to recycle the waste tire. Alternatively, the tire can be directly shredded and then screened to separate the steel wire fragments from the tire pieces. Both methods are cumbersome and cannot simultaneously and completely separate the steel wires from the tire tread and sidewall, reducing the efficiency of tire recycling. The aforementioned application involves shredding the tire and then screening out the steel wires. However, the steel wires are easily embedded in the rubber during the shredding process, and their small size after shredding results in a large amount of steel wire fragments mixed in with the rubber, which is detrimental to rubber recycling and has certain shortcomings. To solve the above problems, a solid waste recycling and processing device for rubber products is proposed. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the present invention provides a rubber product solid waste recycling and processing device, which facilitates the simultaneous and relatively complete separation of the steel wires of the tire tread and sidewall, thereby improving the efficiency of tire recycling and processing.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a rubber product solid waste recycling and processing device, comprising a machine base and a tire, and further comprising a mounting base fixedly disposed on the inner front side of the machine base, a splitting mechanism disposed on the top of the mounting base for splitting out the steel wires embedded in the tire sidewall, and a limiting mechanism disposed at the bottom of the mounting base for limiting the tire.

The inner wall of the movable through groove away from the first mounting sleeve is hinged with a base symmetrically arranged around the center point of the cutting block. The sides of the bases away from each other are fixedly equipped with a first cutting blade for cutting the tire sidewall. The top of the bases near the first mounting sleeve is fixedly equipped with baffles arranged perpendicularly to the bases to limit the steel wires inside the tire sidewall.

The first threaded tube and the third threaded tube are respectively designed as internal threaded tube and external threaded tube. The inner and outer walls of the second threaded tube are both provided with threads so that when the second threaded tube rotates, it synchronously drives the first threaded tube and the second threaded tube to move away from each other or move closer to each other, and can extend the travel of the first threaded tube and the third threaded tube.

The inner wall of the first mounting sleeve is fixedly provided with a second servo motor. The output shaft of the second servo motor is provided with a second transmission mechanism to drive the first threaded rod to rotate synchronously. Through the thread transmission direction of the first threaded rod and the fourth threaded tube, the two fourth threaded tubes are moved away from each other or close to each other.

[0018] Furthermore, the side of the cutting block away from the baffle is designed with a pointed tip, and both sides of the cutting block are provided with inclined surfaces symmetrically arranged around the center point of the cutting block. A second cutting blade is fixedly provided on both sides of the cutting block and between the inclined surfaces.

The straight part of the baffle is in contact with the first cutting blade.

[0020] Furthermore, the compaction mechanism includes:

[0021] A mounting plate is fixedly mounted on the top rear end of the mounting base. A third servo motor is fixedly mounted on the top of the mounting plate. A second threaded rod is fixedly mounted on the output shaft of the third servo motor, and the second threaded rod is rotatably connected to the top of the mounting plate. A fifth threaded tube extending to the bottom of the mounting plate is threadedly connected to the side wall of the second threaded rod.

[0025] Furthermore, the compaction mechanism also includes:

[0026] The marking sleeve is fixedly sleeved on the side wall of the second and third rotating shafts located outside the mounting plate, and the outer diameter of the marking sleeve is smaller than the outer diameter of the first and second transmission gears, so as to limit the influence on the meshing of the first and second transmission gears.

[0027] The marking grooves are formed on the outer wall of the marking sleeve and are arranged in a circular array. After the marking grooves on the outer sides of the second and third rotating shafts are aligned vertically, the rolling blocks on the side walls of the first and second rolling rollers are distributed accordingly.

A limiting roller is rotatably mounted on the inner side of the connecting frame. A second guide rod extending into the mounting base is fixedly mounted on the top of the connecting frame and on both sides of the housing to limit the movement of the connecting frame. A spring is fitted on the side wall of the rod located inside the housing and at the bottom of the second electromagnet. A through hole for fitting the rod is opened at the bottom of the housing, and the inner diameter of the through hole is smaller than the inner diameter of the housing so that the second electromagnet cooperates with the bottom stop of the housing, thereby restricting the separation of the rod from the housing.

[0030] This invention provides a device for recycling and processing solid waste from rubber products. Compared with the prior art, it has the following advantages:

[0031] 1. This invention uses a separation mechanism and a rolling mechanism to facilitate the simultaneous separation of steel wires embedded in the tread and sidewall of rubber tires. The separated steel wires are relatively intact, eliminating the need to crush and screen them, thereby reducing the amount of steel wire residue in the rubber and facilitating subsequent tire recycling.

[0032] 2. The present invention uses a separating mechanism to limit the steel wire embedded in the tire sidewall while cutting the sidewall, and to move the steel wire away from the tire, thereby separating the steel wire embedded in the tire sidewall. It also makes it easy to adjust the inclination of the first cutting blade, thus avoiding the situation where the bottom of the tire sidewall cannot be completely cut due to factors such as the tire sidewall being thicker in some tires, making it easier to actually separate the steel wire from the tire sidewall.

[0033] 3. The present invention facilitates the synchronous adjustment of the tilt of the first cutting blade by using the second threaded tube and the first threaded tube, while increasing the travel of the first threaded tube and the third threaded tube. This allows for improved adjustment of the first and second cutting blades within the limited space of the cutting block, thereby enhancing applicability.

[0034] 4. The present invention drives the second rolling roller to rotate from a position that does not affect the tire installation through the third and fourth transmission mechanisms, thereby avoiding affecting the tire installation. It also facilitates the rotation of the first and second rolling rollers and the tire at the same time through the first and second transmission gears, which is convenient for actual use in separating steel wire.

[0035] 5. The present invention marks the rotation positions of the second and third rotating shafts by marking the sleeve and marking groove, which does not affect the adjustment of the height of the first rolling roller. When the first and second rolling rollers work together to roll the tire, the rolling blocks on the side walls of the first and second rolling rollers are vertically aligned to avoid affecting the rolling effect of the tire.

[0036] 6. The present invention uses a limiting mechanism to limit the bottom of the tire from the inside of the tire, and cooperates with the second rolling roller to further limit the tire, improve the stability of the tire, so as to facilitate the separation of the steel wires on the tire tread and sidewall. The limiting roller is rotatably set to reduce the impact on the rotation of the tire. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0059] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A rubber product solid waste recycling and processing device includes a machine base 1 and a tire 4. It also includes a mounting base 3 fixedly installed on the inner front side of the machine base 1, a splitting mechanism 6 installed on the top of the mounting base 3 for splitting the steel wires embedded in the sidewall of the tire 4, and a limiting mechanism 5 installed on the bottom of the mounting base 3 for limiting the tire 4. The inner wall of the tire 4 can be fitted onto the sidewall of the mounting base 3. A rolling mechanism 2 is provided at the top rear end of the mounting base 3 for rolling the tread of the tire 4 to split the steel wires in the tread.

[0060] Please see Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 and Figure 15 The separation mechanism 6 includes:

[0061] A first mounting sleeve 62 is fixedly mounted on the top of the mounting base 3. A second mounting sleeve 61 is fixedly mounted on the top of the first mounting sleeve 62. Both ends of the second mounting sleeve 61 are movably provided with cutting blocks 67 for puncturing the sidewall of the tire 4. A movable through groove 692 is opened on the top of the cutting block 67. A base 69 is hinged to the inner wall of the movable through groove 692 away from the first mounting sleeve 62, symmetrically arranged with the center point of the cutting block 67. A first cutting blade 691 is fixedly mounted on the side of the base 69 away from each other for cutting the sidewall of the tire 4. A baffle 68 is fixedly mounted on the top of the side of the base 69 close to the first mounting sleeve 62, arranged perpendicularly to the base 69, to limit the steel wire in the sidewall.

[0062] The separation mechanism 6 also includes:

[0063] The fixed base 693 is fixedly disposed on the inner wall of the movable through groove 692 and has a hollow design. The inner wall of the fixed base 693 is slidably provided with a vertically movable first threaded tube 696. The inner wall of the first threaded tube 696 is threadedly connected to a second threaded tube 697, and the inner wall of the second threaded tube 697 is threadedly connected to a third threaded tube 699. The first threaded tube 696 and the third threaded tube 699 are respectively designed as internal threaded tubes and external threaded tubes. The inner and outer walls of the second threaded tube 697 are both provided with threads so that when the second threaded tube 697 rotates, it simultaneously drives the first threaded tube 696 and the second threaded tube 697 to move away from or towards each other, and can extend the travel of the first threaded tube 696 and the third threaded tube 699.

[0064] Hinged member 698 is fixedly disposed at the top of the first threaded tube 696 and the bottom of the third threaded tube 699, and is respectively hinged to the side of the base 69 that is close to each other.

[0065] The separation mechanism 6 also includes:

[0066] Mounting member 6991 is rotatably disposed on the outer wall of the second threaded tube 697 and located at the bottom of the fixed seat 693. The outer wall of mounting member 6991 is fixedly connected to the inner wall of the movable through groove 692 to limit the second threaded tube 697. A sliding member is fixedly provided on the side wall of the hinge member 698 located at the bottom of the third threaded tube 699. The side of the sliding member away from the hinge member 698 is slidably connected to the inner wall of the movable through groove 692.

[0067] The connecting block 65 is fixedly disposed on one side of the cutting block 67 that are close to each other. The first servo motor is fixedly disposed inside the connecting block 65. The output shaft of the first servo motor is provided with a first transmission mechanism 694 to drive the second threaded tube 697 to rotate.

[0068] The separation mechanism 6 also includes:

[0069] The stop block 695 is fixedly installed on the side of the base 69 that is close to each other, and the connection between the stop block 695 and the base 69 is smoothly designed to restrict the steel wire from entering the connection between the base 69 and the movable through groove 692. The top and bottom of the tip of the cutting block 67 are provided with hinge grooves. The side of the stop block 695 away from the base 69 is hinged to the inner wall of the hinge groove. The side wall of the base 69 is in contact with the inner walls of both sides of the movable through groove 692.

[0070] The separation mechanism 6 also includes:

[0071] The fourth threaded tube 63 is slidably disposed on the inner wall of the second mounting sleeve 61 and symmetrically arranged with respect to the center point of the second mounting sleeve 61. The inner wall of each fourth threaded tube 63 is threadedly connected to a first threaded rod 64. The side of the first threaded rod 64 that is close to each other is rotatably connected to the inner wall of the second mounting sleeve 61. The inner wall of the first mounting sleeve 62 is fixedly provided with a second servo motor. The output shaft of the second servo motor is provided with a second transmission mechanism to drive the first threaded rod 64 to rotate synchronously. Through the thread transmission direction of the first threaded rod 64 and the fourth threaded tube 63, the two fourth threaded tubes 63 are moved away from each other or close to each other.

[0072] The side of the cutting block 67 away from the baffle 68 is designed with a pointed tip. Both sides of the cutting block 67 are provided with inclined surfaces symmetrically arranged around the center point of the cutting block 67. A second cutting blade 66 is fixedly provided on both sides of the cutting block 67 and between the inclined surfaces. The connection between the tip of the cutting block 67 and the inclined surfaces on both sides and the second cutting blade 66 is smoothly provided.

[0073] The side of the baffle 68 near the tip of the cutting block 67 is designed to be bent downwards to form an arc-shaped structure that approaches the straight part of the baffle 68. This facilitates the limiting of the baffle 68 while reducing obstruction to the tire sidewall of the tire 4. It avoids the situation where the top baffle 68 of the cutting block 67 cannot move outside the tire 4 at the connection between the tire sidewall and the tread, thus avoiding affecting the separation of the sidewall steel wire. In addition, there is a gap between the bottom of the bend of the baffle 68 and the top of the first cutting blade 691 for the steel wire to enter and exit. The straight part of the baffle 68 fits against the first cutting blade 691 to prevent the steel wire from getting embedded at the connection between the baffle 68 and the first cutting blade 691, thus avoiding affecting the removal of the steel wire.

[0074] In practice, the rubber tire 4 to be recycled is fitted onto the side wall of the mounting base 3, with the inner wall of the tire 4 positioned above the second crushing roller 27 and the cutting mechanism 6. Then, the second servo motor is started. The output shaft of the second servo motor drives the first threaded rod 64 to rotate synchronously via a coupling and a second transmission mechanism. Simultaneously, the rotation of the first threaded rod 64 causes the fourth threaded tube 63 to move away from each other along the inner wall of the second mounting sleeve 61, thereby causing the connecting block 65 and the cutting block 67 to move away from each other, puncturing the tire sidewall from the inside of the tire 4. Then, the cutting block... 67 are separated from each other. Because the side of the cutting block 67 away from the first mounting sleeve 62 is designed with a pointed tip, and under the action of the first cutting blade 691, the number of cutting holes on the tire sidewall is continuously increased, and the bottom of the tire sidewall is completely cut open. At this time, the top of the tire sidewall is still connected to the outside, which makes it easier to expose the steel wire on the tire sidewall. The steel wire embedded in the tire sidewall slides along the tip of the cutting blade and the first cutting blade 691 into the arc-shaped mechanism formed by the bend of the baffle 68 to restrict the position of the steel wire. Thus, as the cutting blades move away from each other, the steel wire embedded in the tire sidewall is separated out.

[0075] As the tire 4 rotates as it is being rolled by the rolling assembly, some of the steel wires are blocked by the baffle 68 and separated from the tire 4. This improves the efficiency of separating the sidewall steel wires from the tire 4 during the rotation of the tire 4. Furthermore, the cutting blades move further away from each other, further improving the efficiency of separating the sidewall steel wires from the tire 4.

[0076] Since the steel wires on the tire sidewall are usually distributed around the circumference of the tire 4, when the tire sidewall is cut by the first cutting blade 691, the first cutting blade 691 continuously squeezes the steel wires. While cutting the tire sidewall, the steel wires enter the inner side of the baffle 68 along the first cutting blade 691, which makes it easier to separate the steel wires according to the distribution of the tire sidewall steel wires.

[0077] Since the tire 4 is constantly rotating, in order to ensure that the sides of the cutting block 67 do not affect the rotation of the tire 4 during the rotation process, a slope is set to reduce the degree of obstruction of the tire 4 by the sides of the cutting block 67. In addition, the tire 4 is cut by the second cutting blade 66 during the rotation process, thereby avoiding affecting the rotation of the tire 4 and thus avoiding affecting the separation of the tread and the sidewall steel wire.

[0078] The second transmission mechanism includes a first bevel gear fixed at one end of the first threaded rod 64 that is close to each other. The output shaft of the second servo motor is fixed with a fourth rotating shaft through a coupling. The side wall of the fourth rotating shaft is fixed with a second bevel gear that meshes with the first bevel gear. Thus, the first bevel gear and the second bevel gear drive the two first threaded rods 64 to rotate synchronously. The meshing transmission direction of the first bevel gear and the second bevel gear is matched with the thread transmission direction of the first threaded rod 64 and the fourth threaded tube 63, so that the fourth threaded tube 63 moves closer or further away from each other, thereby driving the cutting blocks 67 to move closer or further away from each other, so as to facilitate actual cutting of the tire sidewall.

[0079] To avoid situations where the bottom of the tire sidewall cannot be completely cut due to factors such as the thicker sidewall of some tires 4, the first servo motor is activated. The first servo motor drives the second threaded tube 697 to rotate through the first transmission mechanism 694. As the second threaded tube 697 rotates, it drives the first threaded tube 696 and the third threaded tube 699 to move closer or further apart, thereby adjusting the tilt of the first cutting blade 691 to increase the cutting degree of the first cutting blade 691 on the tire sidewall, so as to facilitate adjustment according to the actual processing needs of the tire 4.

[0080] By providing threads on both the inner and outer walls of the second threaded tube 697, the third threaded tube 699 and the first threaded tube 696 can move along the inner and outer walls of the second threaded tube 697 respectively, thereby increasing the travel of the first threaded tube 696 and the third threaded tube 699, and thus improving the adjustment range of the first cutting blade 691 and the second cutting blade 66.

[0081] By adjusting the lead of the threaded connection between the second threaded tube 697 and the first threaded tube 696 and the third threaded tube 699 respectively, the distance that the first threaded tube 696 and the third threaded tube 699 move is the same when the second threaded tube 697 rotates, so as to facilitate practical use. This is the prior art and will not be described in detail here.

[0082] The second threaded tube 697 and the third threaded tube 699 are respectively limited by the mounting part 6991 and the sliding part to improve the stability of operation;

[0083] The first transmission mechanism 694 includes a fifth rotating shaft fixed to the output shaft of the first servo motor via a coupling and a sixth rotating shaft rotatably disposed inside the cutting block 67. The ends of the sixth rotating shaft and the fifth rotating shaft that are close to each other are fixedly fitted with a third bevel gear that meshes with each other. The lower end of the side wall of the sixth rotating shaft and the outer wall of the second threaded tube 697 are fixedly fitted with a first gear that meshes with each other, thereby driving the second threaded tube 697 to rotate via the first servo motor.

[0084] Example 2: Please refer to Figure 6 , Figure 7 and Figure 8 The technical difference between this embodiment and Embodiment 1 is that the compaction mechanism 2 includes:

[0085] Mounting plate 21 is fixedly mounted on the top rear end of mounting base 3. A third servo motor is fixedly mounted on the top of mounting plate 21. A second threaded rod 291 is fixedly mounted on the output shaft of the third servo motor. The second threaded rod 291 is rotatably connected to the top of mounting plate 21. A fifth threaded tube 292 extending to the bottom of mounting plate 21 is threadedly connected to the side wall of the second threaded rod 291. A frame 293 is fixedly mounted on the bottom of the fifth threaded tube 292. A first rolling roller 26 is rotatably mounted on the inner side of the frame 293. A first guide rod extending to the top of mounting plate 21 is fixedly mounted on the top of the frame 293 and on both sides of the fifth threaded tube 292 to limit the movement of the frame 293.

[0086] The second roller 27 is rotatably mounted on the top of the mounting base 3 and is adapted to the first roller 26. Rotating seats are rotatably mounted on both sides of the second roller 27, and the lower end of the rotating seats is fixedly connected to the top of the mounting base 3. A third transmission mechanism 25 is provided on the inner side of the rotating seat inside the second roller 27. A first rotating shaft is provided at the lower end of the third transmission mechanism 25. A fourth transmission mechanism 24 is provided on the side of the first rotating shaft away from the second roller 27 to restrict the third transmission mechanism 25 and the fourth transmission mechanism 24 from obstructing the installation of the tire 4. A second rotating shaft is provided at the upper end of the fourth transmission mechanism 24 extending outside the mounting plate 21.

[0087] The rolling mechanism 2 also includes:

[0088] The first transmission gear 23 is fixedly sleeved on the side wall of the second rotating shaft located inside the mounting plate 21. The center of the side wall of the first rolling roller 26 is fixedly provided with a third rotating shaft extending to the outside of the mounting plate 21. The side wall of the third rotating shaft located inside the mounting plate 21 is fixedly sleeved with a second transmission gear 22 that is compatible with the first transmission gear 23. The rotation of the first rolling roller 26 and the second rolling roller 27 is controlled by the meshing and disengagement of the first transmission gear 23 and the second transmission gear 22. The outside of the mounting plate 21 is fixedly provided with a fourth servo motor. The output shaft of the fourth servo motor is fixedly connected to the second rotating shaft through a coupling.

[0089] The rolling mechanism 2 also includes:

[0090] The marking sleeve 28 is fixedly sleeved on the side wall of the second and third rotating shafts located outside the mounting plate 21, and the outer diameter of the marking sleeve 28 is smaller than the outer diameter of the first transmission gear 23 and the second transmission gear 22, so as to limit the influence on the meshing of the first transmission gear 23 and the second transmission gear 22.

[0091] The marking groove 29 is opened on the outer wall of the marking sleeve 28 and arranged in a ring array. After the marking grooves 29 on the outer side of the second rotating shaft and the third rotating shaft are aligned vertically, the rolling blocks on the side walls of the first rolling roller 26 and the second rolling roller 27 are correspondingly distributed.

[0092] In specific implementation, after the sidewall of tire 4 is cut, the third servo motor is started. The output shaft of the third servo motor drives the second threaded rod 291 to rotate through the coupling. The second threaded rod 291 drives the fifth threaded tube 292 and the frame 293 to move downward under the limit of the first guide rod, so that the tire 4 can be rolled by the first rolling roller 26 and the second rolling roller 27. At this time, the first transmission gear 23 and the second transmission gear 22 are meshed. Then, the fourth servo motor is started. The output shaft of the fourth servo motor drives the second rotating shaft to rotate through the coupling. The second rotating shaft drives the third rotating shaft to rotate through the first transmission gear 23 and the second transmission gear 22. And drives the second rolling roller 27 to rotate through the third transmission mechanism 25 and the fourth transmission mechanism 24. The first transmission gear 23 and the second transmission gear 22 are meshed and drive the first rolling roller 26 and the second rolling roller 27 to rotate and roll the tire tread of tire 4. At the same time, the tire belt can be driven to rotate, so that the steel wires that are actually separated from the tire tread and the sidewall can be used.

[0093] By making the first roller 26 vertically movable, it is convenient to place the tire 4 between the first roller 26 and the second roller 27, thereby facilitating the actual use of rolling the tire tread.

[0094] The roller usually crushes objects by interlocking the crushing blocks arranged on its sidewalls. To ensure that the first roller 26 and the second roller 27 do not affect the next crushing after they are separated, a marking sleeve 28 and a marking groove 29 are set to mark the rotation positions of the second and third rotating shafts. During the process of the first roller 26 moving down to the designated position to crush the tire tread, the marking grooves 29 on the outer sides of the second and third rotating shafts are vertically aligned, so that the crushing blocks on the sidewalls of the roller are vertically aligned, so as to avoid affecting the crushing effect of the tire 4.

[0095] By setting the third transmission mechanism 25, the first rotating shaft is located at the center of the tire 4. The fourth transmission mechanism 24 facilitates the reduction of the meshing and disengagement distance of the first transmission gear 23 and the second transmission gear 22. This allows the first rolling roller 26 and the second rolling roller 27 to roll while the third transmission mechanism 25 and the fourth transmission mechanism 24 drive the second rolling roller 27 to rotate from the center of the tire 4. This avoids affecting the installation of the tire 4 and facilitates the rotation of the tire 4 while the first rolling roller 26 and the second rolling roller 27 are rotated by the first transmission gear 23 and the second transmission gear 22.

[0096] The third transmission mechanism 25 includes a second gear fixedly sleeved on the end of the second rolling roller 27 and the side wall of the first rotating shaft, and the second gear is connected by a chain drive. The fourth transmission mechanism 24 includes a third gear fixedly sleeved on the side wall of the second rotating shaft and the first rotating shaft, and the third gear is connected by a chain drive, so as to drive the second rolling roller 27 to rotate through the second rotating shaft. The side walls of the fourth transmission mechanism 24 and the third rotating shaft are fitted with protective shells, and the third transmission mechanism 25 is set in the rotating seat, thereby protecting the fourth transmission mechanism 24 and other components, and preventing the rubber and other materials after rolling from getting tangled on the third gear and other components, so as to avoid affecting the use.

[0097] The third rotating shaft is provided with a bearing on its side wall. The inner wall of the bearing's inner ring is fixedly connected to the side wall of the third rotating shaft. The outer wall of the bearing's outer ring is fixedly fitted with a bearing seat. The outer wall of the bearing seat is slidably connected to the mounting plate 21, thereby limiting the vertical movement of the third rotating shaft without affecting its rotation.

[0098] Please see Figure 16 and Figure 17 The limiting mechanism 5 includes:

[0099] The housing 52 is fixedly mounted on the bottom of the mounting base 3. A first electromagnet 54 is fixedly mounted on the top of the inner wall of the housing 52, and a second electromagnet 55 is fitted on the inner side wall of the housing 52. A rod 53 extending to the bottom of the housing 52 is fixedly mounted on the bottom of the second electromagnet 55. A connecting frame is fixedly mounted on the bottom of the rod 53. A limiting roller 51 is rotatably mounted on the inner side of the connecting frame. A second guide rod extending into the mounting base 3 is fixedly mounted on the top of the connecting frame and on both sides of the housing 52 to limit the movement of the connecting frame. A spring is fitted on the side wall of the rod 53 inside the housing 52 and at the bottom of the second electromagnet 55. A through hole for fitting the rod 53 is opened at the bottom of the housing 52, and the inner diameter of the through hole is smaller than the inner diameter of the housing 52 so that the second electromagnet 55 cooperates with the bottom stop of the housing 52, thereby restricting the separation of the rod 53 from the housing 52.

[0100] In practice, the first electromagnet 54 and the second electromagnet 55 are activated, causing a repulsive force to be generated on the side where the first electromagnet 54 and the second electromagnet 55 are close to each other. This causes the second electromagnet 55 and the rod 53 to move downward, thereby causing the connecting pipe and the limiting roller 51 to move downward. This limits the bottom of the tire 4 from the inside of the tire 4 and cooperates with the second rolling roller 27 to limit the tire 4, improve the stability of the tire 4, and facilitate the separation of the steel wires on the tire 4 tread and sidewall. The limiting roller 51 is rotatably set to reduce the impact on the rotation of the tire 4.

[0101] In implementation of this invention, a rubber tire 4 requiring recycling is fitted onto the side wall of the mounting base 3, with the inner wall of the tire 4 positioned above the second rolling roller 27 and the splitting mechanism 6. Then, the cutting blocks 67 of the splitting mechanism 6 are inserted into the sidewall of the tire 4 and continuously moved away from each other to split the sidewall of the tire 4. During this splitting process, the steel wire embedded in the sidewall enters the arc-shaped structure formed by the baffle 68 along the first cutting blade 691 to limit the steel wire. Then, the third servo motor is activated, causing the first rolling roller 26 to move downwards, thereby cooperating with the second rolling roller 27 to roll the tread of the tire 4. The tire 4 is pressed to separate the steel wires inside the tread. At the same time, as the first and second rollers 26 and 27 rotate and press the tire 4, the tire 4 will also rotate. This makes it easier to separate the embedded steel wires in the sidewall while pressing the entire tread. This facilitates the simultaneous separation of the embedded steel wires in the tread and sidewall, making it easier to recycle the waste rubber tire 4. After separating the embedded steel wires in the tread and sidewall, the cutting blocks 67 are brought closer together and the first roller 26 is moved upward to remove the separated rubber tire 4. The steel wires inside the baffle 68 are then removed for use in the next recycling process.
