Description

Technical Field

[0001] This invention relates to the field of waste tire processing technology, specifically to a waste tire recycling and processing equipment. Background Technology

[0002] Waste tires refer to tires that have reached the end of their service life and are no longer suitable for continued use. Improper disposal of waste tires can cause serious environmental pollution and occupy a large amount of land resources. Therefore, it is necessary to recycle waste tires.

[0003] When recycling used tires, the sidewalls contain steel wires, so the sidewalls need to be cut and separated from the tread. The steel wires inside the sidewalls are then removed, and the tread is crushed. To facilitate the processing of the sidewalls and the removal of the steel wires, the amount of rubber on the sidewalls should be as small as possible, while the amount of rubber on the tread should be as large as possible. Therefore, when cutting, it is necessary to cut downwards along the edge of the tread. However, since the sidewalls and treads are perpendicular, when the cutting blade cuts downwards, it will cut into the inside of the sidewalls, preventing the sidewalls from being fully separated from the treads. This affects the cutting effect and reduces cutting efficiency. Summary of the Invention

[0004] This invention provides a waste tire recycling and processing device. By using a rotating plate, the sidewall can be supported outward during waste tire cutting, so that the sidewall and the tread at the cutting position can maintain a certain angle, thereby facilitating cutting. This solves the problem mentioned in the background art that when the cutting blade cuts from top to bottom, it will cut into the inside of the sidewall, making it impossible to fully separate the sidewall from the tread, thus affecting the cutting effect and reducing cutting efficiency.

The round rod slides in the groove to make the clamping disk clamp the side ring of the waste tire.

[0010] As an optional solution of the waste tire recycling and processing equipment of the present invention, the end of the round rod is fixed with a sliding protrusion, and the inner wall of the chute is provided with a track groove for the sliding protrusion to slide, the track groove including an inclined part and a vertical part.

[0011] As an optional embodiment of the waste tire recycling and processing equipment of the present invention, the positioning block has a first hydraulic oil groove inside, a first piston plate is slidably arranged in the first hydraulic oil groove, a transmission plate is fixed at the end of the rotating shaft, a first transmission rod is fixed between the transmission plate and the first piston plate, a second hydraulic oil groove communicating with the first hydraulic oil groove is opened inside the rotating plate, a second piston plate is slidably arranged in the second hydraulic oil groove, and a second transmission rod is arranged between the second piston plate and the slider.

[0012] As an optional embodiment of the waste tire recycling and processing equipment of the present invention, the rotating plate includes a rotating part and an extending part. The end of the extending part is fixed with a pin, the pin is elastically disposed in the rotating part, and the end of the pin is elastically connected with a push rod for abutting against the second piston plate.

[0013] As an optional embodiment of the waste tire recycling and processing equipment of the present invention, a second protruding plate is fixed on the surface of the insert post, a second spring is fixed between the second protruding plate and the inner wall of the rotating part, and a third spring is fixed between the bottom of the top rod and the inner wall of the insert post.

[0014] As an optional solution of the waste tire recycling and processing equipment of the present invention, a bracket is fixed on the surface of the fixed base, a servo electric cylinder is fixed on the top of the bracket, the output end of the servo electric cylinder is fixed to the positioning frame, a first servo motor is fixed on the outer surface of the positioning frame, and the output end of the first servo motor is fixed to the cutting blade.

[0015] As an optional embodiment of the waste tire recycling and processing equipment of the present invention, a positioning rod is fixed at the middle position of the fixed disk, the end of the positioning rod is fixed to the bracket, a roller is rotatably arranged on the fixed base, the roller is rotatably sleeved on the outer surface of the positioning rod, the end of the roller is fixed to the disk, a toothed ring is fixed on the outer surface of the roller, a second servo motor is fixed on the surface of the fixed base, and a second gear that meshes with the toothed ring is fixed at the output end of the second servo motor.

[0016] The present invention has the following beneficial effects:

[0017] 1. In this waste tire recycling and processing equipment, when cutting waste tires, the rotating disc drives the waste tire to rotate, which in turn drives the movable rod to rotate. The movable rod drives the ball to slide along the surface of the contact ring, so that the ball contacts the boss. The contact ball drives the movable rod to move left and right. The movable rod drives the rotating shaft to rotate through the meshing of the rack and the first gear, so that the rotating plate can rotate. The rotation of the rotating plate supports the outer ring of the waste tire outward, so that the side ring and the tread at the cutting position can maintain a certain angle, thereby facilitating the cutting and making the separation of the side ring and the tread more complete, resulting in a better cutting effect.

[0018] 2. In this waste tire recycling and processing equipment, when the rotating plate rotates and supports the side ring outward, the rotating shaft drives the transmission plate to rotate. The transmission plate drives the first piston plate to move through the first transmission rod, filling the hydraulic oil in the first hydraulic oil tank into the second hydraulic oil tank. This allows the clamping plate to clamp the edge of the side ring. After the edge of the side ring is clamped, the extension part extends outward, allowing the clamping plate to stretch the edge of the side ring outward. This avoids wrinkling of the side ring towards the tread at the connection between the side ring and the tread. As a result, the side ring and the tread remain taut at the cutting position, making cutting easier and further improving the cutting effect.

[0019] 3. In this waste tire recycling and processing equipment, a third spring is installed. When the side ring can no longer be stretched outward, the second piston plate continues to drive the push rod downward. At this time, the third spring is compressed, which allows the second piston plate to drive the push rod downward, thereby relieving the force on the push rod and preventing the push rod from continuously pushing the extension part outward, thus avoiding jamming. This allows the clamping plate to adapt to the amount of outward stretching of the side ring when stretching it, thereby increasing the safety of the structure. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0035] Example 1, please refer to Figures 1-13 A waste tire recycling and processing device includes a fixed base 1, a disc 3 for placing waste tires 2 is rotatably arranged on the fixed base 1, a positioning frame 4 that can be lifted and lowered is arranged above the disc 3, a pressure roller 5 is rotatably arranged inside the positioning frame 4, and a cutting blade 6 for cutting the waste tires 2 is rotatably arranged outside the positioning frame 4.

[0036] A positioning block 7 is fixed on the outer surface of the disc 3. A rotating shaft 8 is rotatably mounted on the positioning block 7. A rotating plate 9 is fixed on the circumference of the rotating shaft 8. A movable rod 10 is elastically mounted inside the disc 3. A ball 11 is fixed at the end of the movable rod 10. A fixed plate 12 is mounted inside the disc 3. A contact plate 13 is mounted on the outer surface of the fixed plate 12. A boss 14 for contacting the ball 11 is fixed on the outer surface of the contact plate 13. The movable rod 10 moves left and right by sliding along the surface of the boss 14 through the ball 11, causing the rotating plate 9 to rotate. The rotating plate 9 lifts the side ring 201 of the waste tire 2 by rotating.

[0037] An electric push rod 15 is fixed inside the fixed plate 12. The end of the electric push rod 15 is fixed to the contact plate 13. A first gear 16 is fixed on the circumference of the rotating shaft 8. The first gear 16 is rotatably set in the positioning block 7. A rack 17 that meshes with the first gear 16 is fixed at the end of the movable rod 10.

[0038] A first protruding plate 18 is fixed to the surface of the movable rod 10, and a first spring 19 is fixed between the first protruding plate 18 and the inner wall of the disc 3.

[0039] A bracket 38 is fixed to the surface of the fixed base 1, a servo cylinder 39 is fixed to the top of the bracket 38, the output end of the servo cylinder 39 is fixed to the positioning frame 4, a first servo motor 40 is fixed to the outer surface of the positioning frame 4, and the output end of the first servo motor 40 is fixed to the cutting blade 6.

[0040] A positioning rod 41 is fixed at the middle position of the fixed plate 12. The end of the positioning rod 41 is fixed to the bracket 38. A roller 42 is rotatably mounted on the fixed base 1. The roller 42 is rotatably sleeved on the outer surface of the positioning rod 41. The end of the roller 42 is fixed to the disc 3. A toothed ring 43 is fixed on the outer surface of the roller 42. A second servo motor 44 is fixed on the surface of the fixed base 1. A second gear 45 that meshes with the toothed ring 43 is fixed at the output end of the second servo motor 44.

[0041] In this technical solution, when cutting the waste tire 2, the waste tire 2 is first placed on the disc 3, such as... Figure 11 In the state shown, the electric push rod 15 then pushes the contact plate 13 to move, causing the ball 11 to contact the surface of the contact plate 13. The contact plate 13 then drives the boss 14 to move, as shown. Figure 9 As shown, the sphere 11 at point b initially contacts the top of the boss 14. When the contact plate 13 moves the boss 14 to the left, the boss 14 moves the sphere 11 at point b to the left. When the sphere 11 moves to the left, it moves the movable rod 10 to the left. The movable rod 10 moves the first protruding plate 18 to the left, compressing the first spring 19 and storing its force. Simultaneously, the movable rod 10 moves to the left, moving the rack 17 to the left. The rack 17 moves to the left, causing the first gear 16 to rotate counterclockwise. The first gear 16 drives the rotating shaft 8 to rotate, and the rotating shaft 8 drives the rotating plate 9 to rotate, causing the rotating plate 9 at point b to rotate to... Figure 12In the state shown, the side ring 201 of the waste tire 2 is pushed outward, and then the servo cylinder 39 pushes the positioning frame 4 to move downward. The positioning frame 4 drives the pressure roller 5 to move downward, so that the pressure roller 5 presses the tire tread 202. At the same time, the first servo motor 40 starts and drives the cutting blade 6 to rotate, so that the cutting blade 6 can cut the waste tire 2. Then the second servo motor 44 drives the second gear 45 to rotate. The rotation of the second gear 45 drives the gear ring 43 to rotate. The gear ring 43 drives the roller 42 to rotate. The roller 42 drives the disc 3 to rotate. The disc 3 drives the waste tire 2 to rotate, so that the cutting blade 6 performs circumferential cutting on the waste tire 2.

[0042] In this technical solution, the boss 14 includes a rising surface 141, a falling surface 142, and a horizontal surface 143, such as... Figure 9 As shown, whenever the disc 3 drives the movable rod 10 to rotate from position a to position b, the ball 11 first slides along the rising surface 141 of the boss 14, causing the ball 11 to drive the movable rod 10 to move to the left, thereby causing the rotating plate 9 to rotate and push the side ring 201 of the waste tire 2 outward. At this time, the waste tire 2 has not yet rotated to position b. Then the ball 11 slides to the horizontal surface 143 and slides along the horizontal surface 143 to perform the cutting work. When the ball 11 slides from position b to position c, the first spring 19... The reset mechanism moves the movable rod 10 to the right, resetting the rotating plate 9. Finally, when the ball 11 slides from point c to point a, the state of the rotating plate 9 remains unchanged. Through the above process, when the cutting blade 6 cuts the waste tire 2, the rotating plate 9 can support the side ring 201 at the point where the cutting blade 6 contacts the waste tire 2, so that the side ring 201 and the tread 202 have a certain angle, which facilitates cutting along the edge and allows the side ring 201 and the tread 202 to be fully separated, resulting in a better cutting effect.

[0043] In Example 2, when the rotating plate 9 pushes the side ring 201 outward, a bend occurs at the connection between the side ring 201 and the tread 202. During this bend, wrinkles appear near the connection between the side ring 201 and the tread 202. Because the side ring 201 is relatively thinner than the tread 202, wrinkles may occur on the side ring 201 towards the tread 202, leading to excessive cutting of the side ring 201. This may result in the steel wires on the inner wall of the side ring 201 being cut out, thus affecting the cutting effect. To address this problem, this example is an improvement based on Example 1. For details, please refer to [link / reference]. Figures 1-13 A round rod 20 is slidably arranged on the rotating plate 9. A clamping plate 21 is rotatably arranged at the end of the round rod 20. A slider 22 is slidably arranged inside the rotating plate 9. A groove 23 is opened on the surface of the slider 22. The round rod 20 slides in the groove 23 to make the clamping plate 21 clamp the side ring 201 of the waste tire 2.

[0044] The end of the round rod 20 is fixed with a sliding protrusion 24, and the inner wall of the slide groove 23 is provided with a track groove 25 for the sliding protrusion 24 to slide. The track groove 25 includes an inclined part 251 and a vertical part 252.

[0045] The positioning block 7 has a first hydraulic oil groove 26 inside, and a first piston plate 27 is slidably arranged in the first hydraulic oil groove 26. A transmission plate 28 is fixed at the end of the rotating shaft 8. A first transmission rod 29 is fixed between the transmission plate 28 and the first piston plate 27. The rotating plate 9 has a second hydraulic oil groove 30 inside, which communicates with the first hydraulic oil groove 26. A second piston plate 31 is slidably arranged in the second hydraulic oil groove 30. A second transmission rod 32 is arranged between the second piston plate 31 and the slider 22.

[0046] The rotating plate 9 includes a rotating part 901 and an elongated part 902. The end of the elongated part 902 is fixed with a pin 33. The pin 33 is elastically disposed in the rotating part 901. The end of the pin 33 is elastically connected with a push rod 34 for abutting against the second piston plate 31.

[0047] A second protruding plate 35 is fixed to the surface of the insert 33. A second spring 36 is fixed between the second protruding plate 35 and the inner wall of the rotating part 901. A third spring 37 is fixed between the bottom of the push rod 34 and the inner wall of the insert 33.

[0048] In this technical solution, such as Figure 7 and Figure 8 As shown, when the rotating shaft 8 rotates counterclockwise, it also drives the transmission plate 28 to rotate. The transmission plate 28 drives the first piston plate 27 to move via the first transmission rod 29, filling the hydraulic oil inside the first hydraulic oil tank 26 into the second hydraulic oil tank 30. This causes the second piston plate 31 to move downward. The second piston plate 31 drives the slider 22 to move downward via the second transmission rod 32, causing the round rod 20 to slide in the slide groove 23. The round rod 20 drives the sliding protrusion 24 to slide along the inclined portion 251 of the track groove 25, causing the sliding protrusion 24 to move to the right. The sliding protrusion 24 drives the round rod 20 to move to the right, and the round rod 20 drives the clamping plate 21 to move to the right, causing... The clamping disc 21 clamps the edge of the side ring 201. After clamping, the rotating plate 9 rotates, causing the second piston plate 31 to continue moving downward. At this time, the second piston plate 31 contacts the push rod 34. The second piston plate 31 drives the push rod 34 to move downward synchronously. The push rod 34 drives the insert 33 to move downward. The insert 33 drives the extension part 902 to extend outward, thereby increasing the length between the rotating part 901 and the extension part 902. This allows the clamping disc 21 to stretch the edge of the side ring 201 outward, thereby avoiding wrinkles in the side ring 201 towards the tread 202 at the connection between the side ring 201 and the tread 202, thus further improving the cutting effect.

[0049] When the rotating plate 9 at point b supports the side ring 201 to its maximum extent, the side ring 201 between point b and point a will also protrude to different degrees. Therefore, at point a, the clamping plate 21 is located on the outside of the side ring 201. When the rotating plate 9 rotates, it drives the clamping plate 21 to tighten inward, thereby completing the clamping work of the clamping plate 21 on the edge of the side ring 201, preventing the clamping plate 21 from rotating to the inside of the side ring 201, which would prevent the clamping work from being performed. Then, it continues to rotate towards point b, and the extension part 902 extends outward, so that the clamping plate 21 stretches the edge of the side ring 201 outward, thereby keeping the side ring 201 straight while supporting it outward.

[0050] In this technical solution, a third protruding plate 46 is fixed to the surface of the second transmission rod 32, and a fourth spring 47 is fixed between the third protruding plate 46 and the inner wall of the rotating part 901. When the second piston plate 31 drives the second transmission rod 32 to move downward, it drives the third protruding plate 46 to move downward, causing the third protruding plate 46 to compress the fourth spring 47, thus storing force in the fourth spring 47. When the rotating plate 9 is reset, the force can be released through the fourth spring 47, allowing the second piston plate 31 to reset. When the extension part 902 extends outward, the insert post 33 drives the second protruding plate 35 to move downward, and the second protruding plate 35 compresses the second spring 36, causing the third piston plate 32 to move downward. The second spring 36 stores force, and when the second piston plate 31 returns to its original position, the force can be released through the second spring 36, allowing the extension part 902 to return to its original position. The force required to compress the second spring 36 is greater than the force required to compress the fourth spring 47, so that when the second piston rod moves downward and does not contact the top rod 34, only the fourth spring 47 is compressed, and the second spring 36 is not compressed. Therefore, the extension part 902 will not extend during the clamping process. Only when the second piston plate 31 contacts the top rod 34 and the second piston plate 31 continues to move downward can the second spring 36 be compressed, allowing the extension part 902 to extend.

[0051] Because the wrinkles between the side ring 201 and the tread 202 vary during the stretching process, the length to which the side ring 201 can be stretched may differ. Since the stretchable length of the side ring 201 is limited, it may have already been stretched to its maximum length before the extension portion 902 reaches its full length. At this point, the side ring 201 can no longer stretch outwards, but the extension portion 902 still tends to extend further, which can lead to jamming and structural damage. To address this issue, a third spring 37 is provided. The force required to compress the third spring 37 is greater than that required for the second spring. The force required to compress the spring 36 is used when the elongated part 902 extends outward. The second spring 36 and the third spring 37 are compressed first. When the side ring 201 can no longer be stretched outward, since the rotating plate 9 rotates at the same angle each time, the hydraulic oil will continue to fill into the second hydraulic oil groove 30, so that the second piston plate 31 continues to drive the push rod 34 to move downward. At this time, the third spring 37 is compressed, so that the second piston plate 31 can drive the push rod 34 to move downward, thereby relieving the force on the push rod 34 and preventing the push rod 34 from continuously pushing the elongated part 902 to extend outward, thus avoiding the situation of being stuck.

[0052] In this technical solution, the movement of the slider 22 is as follows: initially, the extension part 902 does not extend, and the slider 22 slides downward relative to the extension part 902, causing the clamping plate 21 to perform clamping work. When the extension part 902 extends outward, the second transmission rod 32 and the top rod 34 move synchronously, causing the slider 22 to move synchronously with the extension part 902, and the relative position remains unchanged. The clamping plate 21 continues to perform clamping work. When the extension part 902 can no longer extend and the third spring 37 is compressed, the second transmission rod 32 continues to move downward, causing the slider 22 to continue to move downward relative to the extension part 902. At this time, the slider 22 protrusion slides along the vertical part 252 to avoid the sliding protrusion 24 being jammed, thereby continuing to maintain the clamping work of the clamping plate 21.
