[0025] The bottom of the horizontal sliding plate 10 is fixed with a dovetail slider. A dovetail chute is provided inside the horizontal mounting box 4. The horizontal sliding plate 10 is slidably connected to the horizontal mounting box 4 through the cooperation of the dovetail slider and the dovetail chute. Through the arrangement of the dovetail slider and the dovetail chute, the horizontal sliding plate 10 can slide horizontally inside the horizontal mounting box 4;

[0026] A horizontal optical rod 9 is slidably connected inside the horizontal sliding plate 10. The horizontal optical rod 9 is located inside the horizontal mounting box 4 and fixedly connected to the horizontal mounting box 4.

The rotation of the horizontal rotating column 15 enables the horizontal mounting block 14 to rotate, and further enables the top cover 2 to rotate, facilitating the entry and exit of the materials inside the kneading hopper 1.

[0031] Working principle: Through the operation of the press 3, the pressure inside the kneading hopper 1 can be controlled. By driving the operation of the drive motor 6, the first horizontal threaded rod 7 and the second horizontal threaded rod 8 can rotate. The rotation of the first horizontal threaded rod 7 and the second horizontal threaded rod 8 enables the horizontal sliding plate 10 to slide horizontally outside the horizontal optical rod 9. The sliding of the horizontal sliding plate 10 enables the horizontal connecting plate 12 to move vertically through the inclined rotating rod 11. The vertical movement of the horizontal connecting plate 12 enables the U-shaped support frame 13 to drive the horizontal mounting block 14 to move up and down, and further enables the horizontal mounting block 14 to drive the top cover 2 to move up and down, enabling the rectangular frame 5 to move out of the inside of the kneading hopper 1, facilitating the subsequent rotation of the top cover 2.

[0032] The hydraulic cylinder 17 enables the inclined rotating plate 18 to move.
