Description

Technical Field

[0001] The present invention relates to the technical field of tire processing, in particular to a tire retreading and grinding device. Background Art

[0002] Tire retreading is the process of reprocessing worn tires. The cost of retreading tires is much lower than purchasing new tires. For transportation companies, this can significantly reduce operating costs. Generally speaking, tire retreading involves grinding the tread of the old tire to remove the worn rubber on the surface and prepare for the subsequent application of new tread rubber.

[0003] The utility model patent with announcement number: CN215357571U discloses a heavy-duty truck tire retreading and grinding equipment, including a base, the top of the base is fixedly connected to an L-shaped plate, the surface of the L-shaped plate is slidably connected to a rectangular sleeve, the surface of the rectangular sleeve is fixedly connected to a transfer plate, the end of the transfer plate is fixedly connected to an upper U-shaped bracket, the surface of the upper U-shaped bracket is fixedly connected to a second rotating shaft, the surface of the second rotating shaft is rotatably connected to a second roller, the bottom of the transfer plate is fixedly installed with a driving push rod 1, the bottom of the driving push rod 1 is fixedly connected to a connecting plate, the end of the connecting plate is fixedly connected to a lower U-shaped bracket, the surface of the lower U-shaped bracket is fixedly connected to a rotating shaft 1, the surface of the rotating shaft 1 is rotatably connected to a roller 1, and an adjustment plate is provided on the top of the base.

[0004] However, the above technical solution has certain shortcomings: 1. The above technical solution drives the mirror movement of the two U-shaped brackets by driving the extension and contraction of the push rod 1, thereby fixing the tire. However, this fixing method is likely to cause deformation of the tire in actual use, thereby causing the grinding depth of the tire surface to change during grinding; 2. When the above technical solution is in use, the grinding wheel is driven by the driving motor to rotate to grind the tire surface, and the position of the grinding wheel can be adjusted by sliding the rectangular block in the rectangular groove. However, in actual use, since the tire surface has not only a flat table surface but also an inclined sidewall, a certain degree of angle adjustment is required when grinding the tire surface to achieve all-round grinding, and this technical solution cannot achieve the effect of adjusting the grinding angle. Summary of the Invention

[0005] The object of the present invention is to provide a tire retreading and grinding device to solve the problems raised in the above background art that the clamping of the tire easily causes deformation of the tire and the grinding angle cannot be adjusted.
