The device also includes:

[0025] The center axis 6 is set at the center of the lower surface of the top plate 3. The center of the center axis 6 is movably connected to the fixed ring 7, and the two ends of the fixed ring 7 are connected to the connecting long column 8. The other end of the connecting long column 8 is connected to the cylinder 9, and the lower end of the center of the connecting long column 8 is connected to the fixed block 10. The lower end of the fixed block 10 is fixedly connected to the center ring 11, and the lower end of the center ring 11 is installed with a connecting block 12. The lower end of the connecting block 12 is connected to the tank cover 13. The transmission component is installed at the lower end of the top plate 3 and is used to control the structure of the tank cover 13 to move up and down. When it needs to be opened or closed, When the container is opened, the control system sends a signal to the cylinder 9. After receiving the signal, the cylinder 9 starts to extend and retract. If the cylinder moves downward, it will push the connecting block 12 and the tank cover 13 downward through the connecting long column 8 until the tank cover contacts and seals the container mouth. During the movement of the tank cover, the spiral column 17 serves as a guide mechanism to ensure that the tank cover moves vertically and smoothly. At the same time, the positioning ring 16 is used to fix the tank cover in a specific position to prevent it from excessive movement or dislocation. When the cylinder reaches the preset position and stops moving, the tank cover remains in the desired position to complete the closing operation.

[0026] Furthermore, the transmission assembly is arranged in a bilaterally symmetrical shape with the central axis 6 as the center, and a sealing ring is installed at the lower end of the tank cover 13. The bilateral symmetry prevents tilting during operation, and the sealing ring prevents the internal liquid from flowing out.

[0027] Furthermore, the central shaft 6 is telescopic, and the central shaft 6 moves up and down synchronously with the up and down movement of the tank cover 13 .

[0028] Furthermore, fixed frames 14 are set at both ends of the lower surface of the top plate 3, and the cylinder 9 is installed inside the fixed frame 14, and the lower end of the cylinder 9 protrudes from the surface of the fixed frame 14 and is connected to the connecting long column 8, and the fixed frame 14 supports and fixes the cylinder 9.

[0029] Furthermore, a limiting ring is provided at the connection between the upper end of the central shaft 6 and the top plate 3 , and a limiting ring is also provided at the connection between the lower end of the central shaft 6 and the tank cover 13 , which prevents the fixing ring 7 from colliding with the top plate 3 upward.

[0030] Furthermore, the transmission assembly includes a central shaft 6, a fixed ring 7, a connecting column 8, a cylinder 9, a fixed block 10, a central ring 11, a connecting block 12 and a tank cover 13. The center of the lower surface of the top plate 3 is fixedly connected to the central shaft 6, the center of the central shaft 6 is movably connected to the fixed ring 7, and both ends of the fixed ring 7 are fixedly connected to the connecting column 8. The outer end of the connecting column 8 is fixedly connected to the cylinder 9, and the lower end of the center of the connecting column 8 is fixedly connected to the fixed block 10. The lower end of the fixed block 10 is fixedly connected to the central ring 11, and the lower end of the central ring 11 is fixedly connected to multiple connecting blocks 12. The lower end of the connecting block 12 is connected to the tank cover 13. After receiving the signal, the cylinder 9 starts to telescope. If the cylinder moves downward, it will push the connecting block 12 and the tank cover 13 downward together through the connecting column 8 until the tank cover contacts and seals the container mouth. During the movement of the tank cover, the spiral column 17 serves as a guiding mechanism to ensure that the tank cover moves vertically and smoothly.

[0031] Furthermore, an auxiliary bracket 15 is installed at the center of the connecting block 12, and multiple auxiliary brackets 15 are fixedly connected to a positioning ring 16 at the inner end, and the positioning ring 16 is arranged around the central axis 6, and the auxiliary bracket 15 is movably connected to a spiral column 17 at the outer end, and the upper end of the spiral column 17 is fixedly connected to the top plate 3, and the lower end of the spiral column 17 is fixedly connected to the mounting platform 1. The auxiliary bracket 15 plays a role in enhancing stability and preventing vibration, and the positioning ring 16 is used to fix the tank cover at a specific position to prevent it from excessive movement or dislocation.

[0032] Working principle: When not in use, the tank cover 13 is located at the top of the device and is connected to the cylinder 9 through the connecting block 12, the connecting long column 8 and other components. The cylinder 9 is in an inactive state, the tank cover 13 remains stationary or slightly suspended, and the auxiliary bracket 15, the positioning ring 16 and the spiral column 17 and other components are in the preset position to provide guidance and support for the movement of the tank cover. When it is necessary to open or close the container, the control system sends a signal to the cylinder 9. After receiving the signal, the cylinder 9 starts to extend and retract. If the cylinder moves downward, it will push the connecting block 12 and the tank cover 13 downward together through the connecting long column 8. Move until the tank cover contacts and seals the container mouth. During the movement of the tank cover, the spiral column 17 serves as a guide mechanism to ensure that the tank cover moves vertically and smoothly. At the same time, the positioning ring 16 is used to fix the tank cover in a specific position to prevent it from excessive movement or dislocation. When the cylinder reaches the preset position and stops moving, the tank cover remains in the required position to complete the closing operation. During the whole process, the fixing ring 7, the center shaft 6, the fixing block 10 and the center ring 11 and other components provide stable support and connection to ensure the rigidity and precision of the transmission mechanism. The auxiliary bracket 15 plays a role in enhancing stability and preventing vibration.
