Description

Technical Field

[0001] This utility model relates to the field of waste tire retreading technology, and in particular to a waste tire retreading tread pressing machine. Background Technology

[0002] Tires are circular, elastic rubber products that are mounted on various vehicles or machinery and roll on the ground. Tires are usually mounted on metal rims, supporting the vehicle body, buffering external impacts, making contact with the road surface, and ensuring the vehicle's driving performance. After a long period of use, the tire tread will wear down and the tire needs to be replaced. However, the cost of replacing tires is high, so retreading waste tires is used to reduce costs. When retreading waste tires, a pressing machine is used to press the tread and bond it to the outside of the tire.

[0003] A search revealed that Chinese Patent CN208148562U discloses a waste tire retreading tread pressing machine, comprising a base, two movable plates slidably mounted on the top of the base, and a bearing block rotatably mounted on the side of each movable plate that is close to each other. A first rotating plate and a second rotating plate are respectively fixedly mounted on the side of each bearing block that is close to each other, located above the base. A fixed shaft is fixedly mounted on the side of the second rotating plate that is close to the first rotating plate. A fixed groove is formed on the side of the first rotating plate that is close to the second rotating plate, and the fixed shaft is adapted to the fixed groove. A cavity is formed on the base, and two sliding plates are slidably mounted within the cavity. The tops of the two sliding plates are respectively fixedly connected to the bottoms of the two movable plates. A through hole is formed on one side of the base, communicating with the cavity, and a rotating block is rotatably mounted within the through hole.

[0004] In actual use, this patent has the following drawbacks:

[0005] In this patent, when retreading and pasting the tread onto waste tires, a fixing structure is set up to fix the tire in order to prevent the tire from moving. However, it is not convenient to fix the tire at multiple points at the same time. It is necessary to adjust the fixing structure one by one to fix the tire at a single point to achieve multi-point fixation, which is inefficient. Utility Model Content

A spring 35 connected to the pressing block 34 is provided on the inner wall of the fixing cylinder 31. The cover plate 37 is fixedly located at one end of the fixing cylinder 31. A pressing screw 36 is provided on the outer wall of one side of the conical disc 32, and the pressing screw 36 is threaded through the cover plate 37, which can quickly fix the tire at multiple points and is more efficient.

[0028] In specific implementations, such as Figure 1 As shown, the support frame 1 is provided with a limiting component 4 inside. The limiting component 4 includes a movable frame 41, a limiting plate 42, a hydraulic rod 43, and an insert block 46. The movable frame 41 is slidably connected to the inner wall at the bottom of the support frame 1. The limiting plate 42 is rotatably connected to the movable frame 41 through a rotating shaft. The limiting plate 42 can rotate with the turntable 2.

[0029] Furthermore, a slot 45 is provided on the outer wall of one side of the limiting plate 42, and a plug 46 is provided on the outer wall of one side of the cover plate 37. The plug 46 is compatible with the specifications of the slot 45 and can be inserted into the slot 45 for connecting the cover plate 37 and the limiting plate 42.

[0030] Furthermore, a guide block 44 is provided on the outer wall at the bottom of the movable frame 41, and the guide block 44 is slidably connected to the inside of the support frame 1. The hydraulic rod 43 is fixedly installed on the outer wall of one side of the support frame 1, and the guide block 44 is installed on the output end of the hydraulic rod 43. The hydraulic rod 43 can drive the guide block 44 to move.

[0031] In specific implementations, such as Figure 1 and Figure 4 As shown, a top frame 5 is fixedly installed at the bottom of the support frame 1, and a pressing assembly 6 is installed on the top frame 5. The pressing assembly 6 includes a hydraulic rod 61, a mounting frame 62, and a pressing roller 63.

[0034] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview:

[0035] In use, the tire is fitted over several supporting blocks 33. Rotating the compression screw 36 causes the conical disc 32 to rotate and compress the inclined surface of the compression block 34, which in turn causes the compression block 34 to move the supporting blocks 33. This allows multiple supporting blocks 33 to simultaneously support the inner ring of the tire, achieving simultaneous multi-point fixation. This eliminates the need to adjust multiple fixing structures to fix the tire, resulting in higher efficiency. Activating the hydraulic rod 43 pushes the guide block 44 and the moving frame 41 to move. The moving frame 41 will synchronously drive the limiting disc 42 to move until the insert block 46 is inserted into the slot 45. Apply adhesive to the tire and then attach the end of the tread to the tire. The turntable 2 and the limiting disc 42 can limit the tire and tread. Activating the motor 7 drives the turntable 2 and the fixing cylinder 31 to rotate. The fixing cylinder 31 drives the tire to rotate, causing the tread to wrap around the outer ring of the tire. Activating the hydraulic rod 61 drives the mounting frame 62 and the pressing roller 63 to descend. The pressing roller 63 presses the tread and tire together, adhering the tread to the tire.
