[0002] A tire is a ground-rolling circular elastic rubber product assembled on various vehicles or machines. It is usually made of wear-resistant rubber material and installed on a metal rim. During the tire processing, it is often necessary to grind the inner wall of the tire. Therefore, a tire inner wall grinding device is required.

[0003] A Chinese patent with the publication number CN218746603U discloses an inner wall grinding device for rubber tires, including a workbench, an adjustable tire clamping assembly, a clamping cavity, a support top plate and an adjustable grinding assembly. The clamping cavity is vertically connected to the workbench, the support top plate is connected between the two side clamping cavities, the adjustable grinding assembly is arranged at the bottom of the support top plate, and the adjustable tire clamping assembly is arranged in the two side clamping cavities; when the utility model is in use, the tire can be effectively clamped and fixed, which is convenient for subsequent grinding treatment of the inner wall of the tire.

[0004] For the existing tire inner wall grinding device, when grinding the tire, grinding wheels with corresponding sizes need to be replaced for tires with different diameters. Frequent replacement of grinding wheels not only increases the operation difficulty, but also greatly reduces the work efficiency, and the debris generated during the grinding process cannot be cleaned in time, which easily leads to residual debris on the inner wall of the tire, causing unevenness inside the tire, affecting the dynamic balance of the tire, making the tire unable to rotate smoothly, affecting the grinding effect, and even possibly causing abnormal wear of the tire, shortening the service life of the tire, and at the same time polluting the environment; therefore, a tire inner wall grinding device is proposed for the above problems. Content of the Utility Model

A threaded hole is opened on the activity sleeve, a locking bolt is rotationally assembled in the threaded hole, and the end of the locking bolt abuts against the outer surface of the hollow tube. When grinding the tire, the activity sleeve is moved downward along the hollow tube, forcing the second swing rod to move accordingly, so that the first swing rod drives the grinding wheel to move until the grinding wheel moves to contact the inner wall of the tire. Through the action of the locking bolt, the activity sleeve is fixed, so that the corresponding position of the grinding wheel can be adjusted according to tires of different diameters, and the grinding requirements of the inner walls of tires with different diameters can be met without frequently replacing the grinding wheel, greatly improving the grinding efficiency.

[0012] The beneficial effects of the present utility model are as follows:

[0013] 1. When the present utility model grinds the tire, the movable sleeve moves downward along the hollow tube, forcing the second swing rod to move accordingly, so that the first swing rod drives the grinding wheel to move until the grinding wheel moves to contact the inner wall of the tire. Through the action of the locking bolt, the movable sleeve is fixed, so that the corresponding position of the grinding wheel can be adjusted according to tires of different diameters. Without frequently replacing the grinding wheel, the grinding requirements of the inner walls of tires of different diameters can be met, greatly improving the grinding efficiency;

[0014] 2. During the grinding process of the present utility model, the negative pressure pump is started to extract the gas in the debris collection box through the suction pipe and discharge it through the exhaust pipe, making the inside of the debris collection box in a negative pressure state.

[0027] Working principle: In the existing tire inner wall grinding device, when grinding a tire, grinding wheels 8 of corresponding sizes need to be replaced for tires of different diameters. Frequent replacement of the grinding wheels 8 not only increases the operation difficulty but also greatly reduces the work efficiency. Moreover, the debris generated during the grinding process cannot be cleaned in time, easily resulting in debris remaining on the inner wall of the tire, causing unevenness inside the tire, affecting the dynamic balance of the tire, making the tire unable to rotate smoothly, affecting the grinding effect, and even possibly causing abnormal wear of the tire, shortening the service life of the tire, and at the same time polluting the environment. Therefore, a tire inner wall grinding device is proposed to solve the above problems. When grinding a tire, first place the tire to be ground between two auxiliary guide wheels 26. Then rotate the rotating disk 30 to make the threaded rod 28 drive the limit frame 29 to move vertically downward until the limit frame 29 moves down to contact the tire surface, so as to limit and fix the tire. After the tire is limited and fixed, move the movable sleeve 10 along the hollow tube 4, forcing the second swing rod 12 to move accordingly, and making the first swing rod 6 drive the grinding wheel 8 to move until the grinding wheel 8 moves to contact the inner wall of the tire. Then, through the action of the locking bolt 14, fix the movable sleeve 10, so that the corresponding position of the grinding wheel 8 can be adjusted according to tires of different diameters. Without frequent replacement of the grinding wheel 8, the grinding requirements of the inner walls of tires of different diameters can be met, greatly improving the grinding efficiency. After the grinding wheel 8 is adjusted to contact the inner wall of the tire, when grinding, start the first motor 9 to make the grinding wheel 8 rotate, and at the same time start the second motor 27 to make the auxiliary guide wheels 26 rotate, thereby forcing the tire to rotate accordingly, so as to perform rotational grinding on the tire, enabling all-round grinding of the inner wall of the tire and greatly improving the grinding effect.

The dust debris generated during the grinding process is sucked into the dust suction hood 15 and then enters the debris collection box 16 through the dust suction pipe 17, so as to clean and collect the debris generated during the grinding process in time, avoid the phenomenon of debris remaining inside the tire and causing unevenness of the inner wall of the tire, keep the inside of the tire flat, enable the tire to rotate and grind smoothly, ensure the grinding effect, prevent the tire from showing abnormal wear, extend the service life of the tire, and at the same time avoid environmental pollution.
