[0002] With the development of modern society, more and more families have bought cars. Cars have brought convenience to people's travel. However, in order to ensure the safety of daily driving, car tires should be inspected and replaced regularly, and the replaced waste tires need to be cut, crushed and recycled.

[0003] After searching, the announcement number is CN213081997U, and the name is a waste tire cutting device, including: a clamp mechanism for fixing the tire in the cutting position and rotating the tire around its own axis. Through research and analysis, it is found that although it has the advantages of completing all-round cutting of large tires and reducing the dependence on manual labor in cutting large tires, it still has the following disadvantages to a certain extent.

[0004] For example, as the cutting process progresses, the rotating cutting knife is easily in contact with the clamping mechanism, causing damage to the rotating cutting knife. At the same time, as the waste tire cutting decreases, the clamping effect of the clamping mechanism on the waste tire becomes worse, affecting the cutting of the latter half of the waste tire and failing to meet the use requirements. In order to solve the above technical problems, we have designed a waste tire recycling and cutting device. Utility Model Content

[0021] The limiting conveying mechanism 5 includes a housing 51, a slider 52, a hydraulic cylinder 1 53, a rotating rod 54, a pressure roller 55, a self-locking motor 56, a bevel gear 57, an outer clamping plate 58, a connecting plate 59, an inner abutment plate 510 and a roller 511, and the cutting mechanism 6 includes a supporting plate 61, a hydraulic cylinder 2 62 and a cutter 63.

[0022] See also Figure 1 and Figure 3The back side of the shell 51 is fixedly connected to the front side of the frame 4 by bolts. There are two sliders 52, and both are slidably engaged on the surface of the shell 51. By setting the slider 52, the hydraulic cylinder 53 is operated to move, thereby driving the rotating rod 54 and the connecting plate 59 to move. There are two hydraulic cylinders 53, and they are respectively fixedly connected to both sides of the shell 51 by bolts. The output end of the hydraulic cylinder 53 passes through the shell 51 and is fixedly connected to one side of the slider 52. One end of the rotating rod 54 is rotatably embedded in the top of the slider 52 on the right side through a bearing, and the lower end of the rotating rod 54 is fixedly connected to the top of the pressure roller 55.

[0023] See also Figure 2 and Figure 3 The bottom of the self-locking motor 56 is fixedly connected to the back of the slider 52 on the right side through a support. There are two bevel gears 57, which are respectively fixedly connected to the rotating shaft of the self-locking motor 56 and the upper end of the rotating rod 54. By setting the bevel gear 57, the rotating rod 54 is driven by the self-locking motor 56, so that the pressure roller 55 is rotated. The two bevel gears 57 are meshed with each other, and the top of the outer clamping plate 58 is fixedly connected to the bottom of the slider 52 on the right side through a support rod.

[0024] See also Figure 1 and Figure 3 One end of the connecting plate 59 is fixedly connected to the left side of the slider 52 on the left side. By setting the connecting plate 59, the inner abutment plate 510 is indirectly connected to the slider 52 on the left side, so that the slider 52 on the left side can drive the inner abutment plate 510 to move when it moves. The other end of the connecting plate 59 is fixedly connected to the left side of the inner abutment plate 510. Both ends of the roller 511 are rotatably embedded in the right side of the surface of the inner abutment plate 510 through bearings. By setting the roller 511 and the pressure roller 55, which are in contact with the inner surface and outer surface of the waste tire respectively, the waste tire can be fixed, and at the same time, the waste tire can be rotated under the rotation of the pressure roller 55.

[0025] See also Figure 1 One end of the support plate 61 close to the platform body 1 is fixedly connected to the right side of the platform body 1, one side of the hydraulic cylinder 2 62 is fixedly connected to the surface of the upper end of the support plate 61 by bolts, and the output end of the hydraulic cylinder 2 62 passes through the support plate 61 and is fixedly connected to the right side of the cutter 63.

By setting the roller 7, the resistance encountered by the waste tire during rotation and cutting is reduced. A collecting frame 8 is placed on the right front side of the top of the platform body 1. By setting the collecting frame 8, the cut waste tire strips are collected.

[0027] When in use, the two sliders 52 are moved to both sides by controlling the retraction of the two hydraulic cylinders 53, thereby causing the connecting plate 59 and the inner plate 510 to move to the left and the outer plate 58 to move to the right, so that the waste tire is placed on the placement plate 3, and the extension of the electric telescopic rod 2 is controlled to move the placement plate 3 and the waste tire upward, and then the electric telescopic rod 2 is stopped and the two hydraulic cylinders 53 are extended, so that the two sliders 52 move toward each other, thereby inserting the inner plate 510 into the inner cavity of the waste tire and the outer plate 58 is clamped on the outer surface of the waste tire, so that the roller 511 on the inner plate 510 contacts the inner wall of the waste tire and the pressure roller 55 contacts the inner wall of the waste tire. The surface contact of the waste tire can fix the waste tire and effectively avoid movement during the cutting process. The cutting position is kept in a tight state through the cooperation of the inner plate 510 and the outer clamping plate 58. The cutter 63 is moved back and forth by controlling the extension and retraction of the hydraulic cylinder 62 to cut off the entire waste tire. During the cutting process, the cutter 63 will not contact the clamp. Then, the self-locking motor 56 is controlled to rotate in clearance. Under the transmission of the bevel gear 57, the rotating rod 54 and the pressure roller 55 are moved in clearance, so that the waste tire can be rotated and transported in clearance, and then the reciprocating movement of the cutter 63 is coordinated to continuously cut the waste tire.

[0028] In summary, the waste tire recycling and cutting device, through the cooperation of the platform 1, the electric telescopic rod 2, the placement plate 3, the frame 4, the limit conveying mechanism 5 and the cutting mechanism 6, solves the problem that the cutting knife rotating with the cutting is easy to contact with the clamping mechanism, and at the same time, as the waste tire cutting is reduced, the clamping effect of the clamping mechanism on the waste tire becomes worse, affecting the cutting of the second half of the waste tire.
