Usually, a suction cup with adsorption function is used to achieve this purpose. Through the design of the suction cup, the close adhesion between the tire body and the drum can be ensured, so that the tire body obtains uniform force distribution during the molding process. The suction cup can also help improve production efficiency and reduce manual operation. In general, the suction cup plays an important role in the radial tire building machine, not only helping to ensure the adhesion and stability of the tire body, but also improving production efficiency and product quality.

[0031] In this embodiment, by opening the cover 811, lubricating oil is poured into the lubricating sponge 89 through the oil inlet 810. Then, the connecting tube 7 is inserted into the designated position inside the fixed tube 5. The screw 81 is rotated to cause threaded movement with the connecting sleeve 6.

[0032] For details, please refer to Figure 4 , Figure 5 The upper end of the screw 81 is fixedly connected to a rotating plate 82, and the upper end of the rotating plate 82 is fixedly connected to a handle 83.

[0033] In this embodiment, a handle 83 is designed to drive the rotating plate 82 to rotate.

[0034] For details, please refer to Figure 5 The connecting sleeve 6 is provided with a lubricating sponge 89 inside, and the lubricating sponge 89 is in contact with the screw 81.

[0035] In this embodiment, the screw 81 can be lubricated by designing a lubricating sponge 89.

[0036] For details, please refer to Figure 6 The groove 814 is provided with a ball bearing 815 inside, and the ball bearing 815 contacts the guide rod 813.

[0037] In this embodiment, by designing the ball 815, the friction between the guide rod 813 and the connecting sleeve 6 can be reduced.

[0038] Specifically, please refer to Figure 7 The dismounting mechanism 11 comprises a sliding groove 111, the inside of the fixed plate 10 is provided with the sliding groove 111, the inside of the sliding groove 111 is slidably connected with a sliding block 112, the inside of the mounting block 9 is provided with a spring 113, the inside of the mounting block 9 is provided with a sliding slot 114, the inside of the sliding slot 114 is slidably connected with a sliding plate 115, the upper end of the sliding plate 115 is fixedly connected with a moving plate 116, the mounting block 9 is in contact with the moving plate 116, the inside of the sliding plate 115 is fixedly connected with a wear-resistant sleeve 119, the inside of the wear-resistant sleeve 119 is slidably connected with a connecting rod 1110, both ends of the connecting rod 1110 are fixedly connected with the mounting block 9, the inside of the mounting block 9 is provided with a clamping groove 1111, the inside of the clamping groove 1111 is clamped with an elastic clamping block 1112, the elastic clamping block 1112 is fixedly connected with the sliding block 112, the mounting block 9 is slidably connected with the sliding block 112, and the outside of the sliding block 112 is fixedly connected with the sliding plate 115.

[0039] In this embodiment, by pulling the sliding block 112 to move, the sliding block 112 moves to the specified position, and then the vacuum generator 3 drives the mounting block 9 and the sliding block 112 and other components to move to the specified position on the suction cup main body 2, and then the sliding block 112 is moved into the sliding groove 111, so that the vacuum generator 3 and other components are limited, and the vacuum generator 3 on the device is convenient to install.

[0040] Specifically, please refer to Figure 7 One end of the spring 113 is fixedly connected with the sliding block 112, and the other end of the spring 113 is fixedly connected with the mounting block 9.

[0041] In this embodiment, by designing the spring 113, the sliding block 112 has elastic force.

[0042] Specifically, please refer to Figure 7 The upper end of the moving plate 116 is fixedly connected with a fixed block 117, and the upper end of the fixed block 117 is fixedly connected with a moving ring 118.

[0043] In this embodiment, by designing the moving ring 118, the fixed block 117 can be driven to move.

[0044] Working principle: When the vacuum generator 3 on the device needs to be installed, the moving ring 118 is pulled towards the spring 113. The movement of the moving ring 118 drives the fixed block 117 to move, the movement of the fixed block 117 drives the moving plate 116 to move, the movement of the moving plate 116 drives the sliding plate 115 to move, the movement of the sliding plate 115 drives the wear-resistant sleeve 119 and the slider 112 to move, the movement of the slider 112 drives the elastic locking block 1112 to move, the elastic locking block 1112 moves out of the locking slot 1111, and the movement of the slider 112 compresses the spring 113. After the slider 112 moves to the designated position, the spring 113 is compressed. The vacuum generator 3 moves toward the suction cup body 2. The movement of the vacuum generator 3 drives the mounting block 9, the moving ring 118, and the slider 112 to a designated position on the suction cup body 2. Then the moving ring 118 is released, and the elastic force of the spring 113 pushes the slider 112 to move. The movement of the slider 112 drives the elastic block 1112 and the sliding plate 115 to move. After the slider 112 moves into the slide groove 111, the elastic block 1112 is engaged in the slot 1111, thereby limiting the vacuum generator 3 and other components, making it easier to install the vacuum generator 3 on the device.

[0045] Before using the device, the movable connecting pipe 7 is inserted from the connecting sleeve 6 into the designated position inside the fixed pipe 5. Then, the cover 811 is rotated to cause threaded movement with the oil inlet 810, resulting in relative displacement of the cover 811. The cover 811 rotates out of the oil inlet 810, and then lubricating oil is poured into the oil inlet 810. The lubricating oil in the oil inlet 810 flows onto the lubricating sponge 89, which lubricates the screw 81. Then, the handle 83 is rotated, which drives the rotating plate 82 to rotate, which in turn drives the screw 81 to rotate. The screw 81 rotates and connects with the connecting pipe 5. When the connecting sleeve 6 undergoes threaded movement, it causes the screw 81 to undergo relative displacement. The rotation of the screw 81 drives the moving sleeve 84, the annular sleeve 85, the annular groove 86, the bolt 87, and the rotating block 88 to move downward. The downward movement of the moving sleeve 84 drives the fixed sleeve 812 to move downward. The downward movement of the fixed sleeve 812 drives the guide rod 813 and the sealing sleeve 816 to move downward. The sealing sleeve 816 moves downward and contacts the fixed pipe 5 and the connecting pipe 7 at the designated position, thereby sealing the connection between the fixed pipe 5 and the connecting pipe 7 and preventing gas leakage at the connection between the fixed pipe 5 and the connecting pipe 7 on the device.

[0046] Given the current problem of localized deformation and denting of parts caused by the suction cup structure of the molding machine's body drum, the structure of the suction cup body 2 has been redesigned: the original suction cup body 2 directly adopted a circular hollow structure for adsorption, which caused parts to be locally adsorbed into the hollow suction cup body 2, ultimately resulting in denting and deformation. The new structure of the body drum suction cup body 2 adopts a ring-shaped structure for adsorption, reducing the problem of hollow center of the suction cup and preventing denting and deformation of parts when they are adsorbed.

[0047] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
