[0003] Cleaning problem: Since the tire needs to be fixed and clamped during smearing, it is difficult for workers to clean the inner wall of the tire completely, resulting in incomplete cleaning. The stains or impurities remaining on the inner wall of the tire can affect the adhesion effect of the mute cotton back glue and the inner wall of the tire, causing poor adhesion, and even causing the mute cotton to fall off.

[0004] Lamination problem: The size of the mute cotton is relatively long, and manual smearing is prone to problems such as snake-shaped walking, misalignment of the gap between the two cottons, etc. Such misalignment not only causes the mute cotton to deviate, but in severe cases, it can even be pasted to the deformation area of the tire, affecting the service life of the mute cotton and reducing its noise reduction performance.

[0005] Compression problem: After the mute cotton is pasted to the inner wall of the tire, it usually needs to be pressed by hand to ensure firm adhesion with the inner wall of the tire. However, the pressure distribution of manual pressing is uneven, which can cause insufficient adhesion of the mute cotton back glue to the inner wall of the tire, and further cause the mute cotton to fall off, affecting the performance of the tire.

The structure of the second roller frame is the same as that of the first roller frame 3, both of which are designed as inverted trapezoids to ensure the stability of the structure and the symmetry of the function.

[0036] Specifically, the first roller shaft 5 assembly includes a first support rod 4 and a roller shaft 5. The first support rod 4 penetrates the roller shaft 5 along the axis of the roller shaft 5. The second roller shaft 5 assembly, the third roller shaft 5 assembly, and the fourth roller shaft 5 assembly have the same structure as the first roller shaft 5 assembly.

[0037] The included angle between the first support rod 4 and one of the sub-frames is ninety degrees.

[0038] The rollers on the first roller assembly, the rollers on the second roller assembly, the rollers on the third roller assembly, and the rollers on the fourth roller assembly can rotate synchronously with the tire. This synchronous rotation design effectively ensures the stability of the tire during rotation, avoiding the phenomenon of tire deviation or slipping. At the same time, through the tight fitting of the rollers and the tire, the stability of the clamping device and the reliability of the operation are further improved, ensuring that the tire always maintains precise alignment and firm fixation during rotation and clamping.

[0039] Specifically, the distance adjusting assembly comprises a bidirectional screw rod 6, a first optical axis 7 and a second optical axis 8, the bidirectional screw rod 6 is arranged in parallel with the first optical axis 7 and the second optical axis 8, and the bidirectional screw rod 6 is located between the first optical axis 7 and the second optical axis 8, the first optical axis 7, the second optical axis 8 and the bidirectional screw rod 6 penetrate the first roller frame 3 and the second roller frame respectively, and the bidirectional screw rod 6 is configured to drive the first roller frame 3 and the second roller frame to move linearly along the axial direction of the bidirectional screw rod 6 to approach or move away from each other.

The first roller frame 3 is arranged at one end of the bidirectional screw rod 6, and the second roller frame is arranged at the other end of the bidirectional screw rod 6. By rotating the bidirectional screw rod 6 by shaking the handle 17, the first roller frame 3 and the second roller frame can be controlled to move linearly along the axial direction of the bidirectional screw rod 6 to approach or move away from each other, so that the position of the roller frame can be flexibly adjusted according to the width of the tire, and stable support to the tire is realized. The design improves the applicability and adjustment accuracy of the device, and enhances the convenience of use.

[0041] The first optical axis 7 and the second optical axis 8 play a role in guiding and stably supporting the first roller frame 3 and the second roller frame along the axial direction of the bidirectional screw rod 6, and the first roller frame 3 and the second roller frame can slide on the first optical axis 7 and the second optical axis 8.

[0042] Specifically, the shaft assembly comprises a driving shaft 9 and a driven shaft 10, the driving shaft 9 and the driven shaft 10 are arranged in horizontal parallel, the distance between the driving shaft 9 and the driven shaft 10 is less than the length of the first roller frame 3, and the output end of the motor 2 is connected with the driving shaft 9.

[0043] The motor 2 drives the driving shaft 9 to rotate, and due to the friction between the driving shaft 9 and the tire contact surface, the rotation of the driving shaft 9 drives the tire to rotate synchronously, so that the tire rotates smoothly between the driving wheel and the driven wheel. When the worker completes the processing of the inner wall of the tire close to the ground, the tire can be continuously rotated by starting the motor 2 to drive the tire, so that the other part of the inner wall of the tire can be continuously processed. This design significantly improves the convenience of the worker's operation and reduces the workload of manually adjusting the position of the tire.

[0044] In addition, when the worker needs to apply cleaning agent or perform scrubbing operation on the inner wall of the tire, the motor 2 is controlled to drive the tire to rotate slowly at a low speed, and the inner wall of the tire is uniformly cleaned or processed, further improving the efficiency and cleaning effect of the operation.

[0045] Specifically, the pressing device comprises a first linear module 11, a second linear module 12, a support 13 and a pressure roller assembly, the first linear module 11 is horizontally arranged, the output end of the first linear module 11 is connected with the second linear module 12, the output end of the second linear module 12 is connected with the support 13, and the tail end of the support 13 is connected with the pressure roller assembly.

[0047] The pressure roller can rotate on the pressure roller frame 15, and when the silent cotton is loaded, the first linear module 11 and the second linear module 12 are controlled to drive the pressure roller to move downward, so that the pressure roller is tightly pressed on the surface of the silent cotton on the inner wall of the tire. Then, the tire is driven to rotate by the rotating shaft assembly, so that the pressure roller uniformly rolls on the inner wall of the tire, thereby uniformly compacting and firmly adhering the silent cotton on the inner wall of the tire. In this process, the two ends of the pressure roller are respectively provided with the positioning strips 16 for limiting the position of the silent cotton, preventing the silent cotton from being offset or misaligned during the pressing process, and ensuring the accurate positioning and stable adhesion of the silent cotton. This design not only improves the adhesion efficiency and quality of the silent cotton, but also avoids the problem of unstable adhesion caused by offset, thereby enhancing the practicability and reliability of the device.

[0048] The working principle of the utility model is as follows: first, the tire is placed on the rotating shaft assembly, the positions of the first roller frame and the second roller frame are adjusted by the bidirectional screw rod, so that the first roller frame and the second roller frame are tightly adhered to the two sides of the tire respectively, thereby forming stable support for the tire. Then, the motor is started, and the motor drives the driving shaft to rotate the tire slowly. The worker uniformly applies cleaning agent to the inner wall of the tire during the rotation of the tire, and performs comprehensive cleaning on the inner wall of the tire.

[0049] After cleaning, the workers lay the sound-absorbing wool on the inner wall of the tire, and then move the pressing wheel to the upper surface of the sound-absorbing wool by controlling the pressing wheel and apply pressure to the sound-absorbing wool. Start the motor again to drive the tire to rotate slowly, so that the pressing wheel rolls evenly on the inner wall of the tire, evenly compacts and firmly adheres the sound-absorbing wool to the inner wall of the tire, and finally completes the installation of the sound-absorbing wool. The process is simple to operate, has high adhesion precision, and ensures the installation quality and use effect of the sound-absorbing wool.

[0050] The pressing wheel is 100% centered with the center line of the tire station, ensuring that the center line of the sound-absorbing wool completely matches the center line of the inner wall of the tire, solving the problem of improper adhesion such as serpentine walking. The pressing roller matched with the size of the tire is used for uniform pressing, ensuring that the sound-absorbing wool back glue is fully adhered to the inner wall of the tire, and avoiding falling phenomenon. The device integrates cleaning, wool sticking and pressing into one station, greatly reducing the size of the device, so that it can be placed flexibly in a small room or warehouse corner, reducing the floor area.

[0051] At the same time, the device design focuses on easy operation, compact structure, strong durability and other characteristics, with light overall weight and low manufacturing cost, realizing the economic benefits of low investment and high return. Through the transformation of the device, not only the sticking efficiency and quality are improved, but also the 100% centering without affecting the tire dynamic balance is ensured, and the falling problem caused by insufficient pressing is fundamentally solved. In addition, the device has the effects and flexibility of the production line sticking, has the advantages of high efficiency, precision, compactness and low cost, and is suitable for various application scenarios.
