[0020] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0021] This embodiment proposes a spiral automatic lid opening mechanism, including a box 1, a lifting cylinder 6, and a needle roller bearing 15. The box 1 is a material box for mechanical equipment such as a ball mill. The lifting cylinder 6 and the needle roller bearing 15 are combined with a rotary structure, which enables the sealing lid 14 to perform a lid opening operation.

[0022] like Figures 1-2 As shown, a can opening 2 is provided on the top of the box body 1, a fixed seat 3 is provided on the box body 1 on one side of the can opening 2, a support shaft 4 is provided on the fixed seat 3, and an installation plate 5 is rotatably provided on the lower end of the support shaft 4.

[0023] The cylinder body 7 of the lifting cylinder 6 is fixedly installed on the mounting plate 5. The upper end of the piston rod 8 of the lifting cylinder 6 is provided with a connecting plate 9. The connecting plate 9 is provided with a lifting plate 10 that can cooperate with the support shaft 4. The lower part of the lifting plate 10 is provided with a sleeve 11 that can cooperate with the support shaft 4. When the lifting cylinder 6 is activated, the sleeve 11 can be driven to move up and down on the support shaft 4 through the lifting plate 10.

[0024] A mounting hole 12 is provided on one side of the upper end of the sleeve 11, and a cover plate 13 is provided on the other side of the sleeve 11. A sealing cover 14 that can cooperate with the can opening 2 is provided under the cover plate 13. When the sealing cover 14 covers the can opening 2, it ensures that the box 1 will not leak.

[0025] The needle roller bearing 15 is inserted into the mounting hole 12. The upper outer side of the support shaft 4 is provided with a guide groove 16 that can cooperate with the needle roller bearing 15. The needle roller bearing 15 cooperates with the guide groove 16 to guide the upward rotation of the sleeve 11.

[0026] Furthermore, the upper half of the guide groove 16 is spiral-shaped. After the sleeve 11 rises to a certain position, the needle roller bearing 15 spirals up, guiding the sleeve 11 to rotate. The sealing cover 14 rotates with the sleeve 11, and the can opening 2 is completely exposed, which facilitates filling.

[0027] Furthermore, the mounting plate 5 is provided with an assembly hole 17 that can cooperate with the support shaft 4. A radial bearing 18 is provided between the assembly hole 17 and the support shaft 4. The radial bearing 18 makes the mounting plate 5 rotate flexibly on the support shaft 4. An inwardly protruding spacer 19 is provided in the middle of the assembly hole 17. The spacer 19 is used to separate the two radial bearings 18 and limit their movement.

[0028] Furthermore, the lower end of the support shaft 4 is provided with a limiting boss 20 for fixing the radial bearing 18. The limiting boss 20 can limit the radial bearing 18 located above and prevent axial movement.

[0029] Furthermore, a positioning plate 21 is provided on the fixed base 3, and the lower end of the support shaft 4 is connected to the positioning plate 21 by a connector 22, so that the positioning plate 21 can securely fix the support shaft 4.

[0030] Furthermore, a sealing ring 23 is provided at the lower end of the sealing cover 14. The sealing ring 23 is an airbag sealing ring, which provides a better sealing effect.

[0031] Furthermore, a reinforcing rib 24 is provided between the cover plate 13 and the sleeve 11. The reinforcing rib 24 makes the cover plate 13 firmly as a whole and prevents the sealing cover 14 from being misaligned.

[0032] Working principle: When this utility model is in use, the sealing cover 14 and the can opening 2 are usually in a matching state to seal the box 1; when the can opening 2 needs to be opened, air is supplied to the lifting cylinder 6, the piston rod 8 of the lifting cylinder 6 rises, and the sleeve 11 is driven to rise along the support shaft 4 through the lifting plate 10. The sleeve 11 uses the cover plate 13 to drive the sealing cover 14 to disengage from the can opening 2, and the can opening gradually opens.

[0033] At this time, the needle roller bearing 15 moves upward along the guide groove 16. When the needle roller bearing 15 moves to the upper half of the guide groove 16, because the upper half of the guide groove 16 is spiral, the sleeve 11 and the needle roller bearing 15 will spiral up, guiding the sleeve 11 to rotate. The sealing cover 14 rotates with the sleeve 11, and the can opening 2 is completely exposed, which is convenient for filling.

[0034] It is understood that the above embodiments are merely exemplary models used to illustrate the principles of this utility model, and this utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
