The power mechanism III can be fixedly connected to the transverse cylinder 32 by conventional fixing means such as screws. The output shaft of the power mechanism III starts to rotate, and the output shaft of the power mechanism III drives the rotating disk 33 to rotate. When the rotating disk 33 rotates, it drives the plurality of rotating cylinders 35 to rotate with the rotation center of the rotating disk 33 as the axis.

The inside of the rotating cylinder 35 squeezes the multiple elastic petals 38, and the raw materials on the multiple elastic petals 38 are scraped off, so that no raw materials remain on the multiple elastic petals 38, thereby keeping the multiple elastic petals 38 clean, which is convenient for the next mixing process; Further, during the material discharging process, the power mechanism I is started. The output shaft of the power mechanism I drives the lead screw 23 to rotate. When the lead screw 23 rotates, it drives the transverse movement cylinder 32 to move through the thread, so that the two transverse movement cylinders 32 move closer to each other. The two transverse movement cylinders 32 move closer to squeeze the raw materials that have been mixed in the mixing cylinder 11. Then, the power mechanism II is started. The output shaft of the power mechanism II drives the driving wheel 24 to rotate, and the driving wheel 24 drives the rotating sleeve 41 to rotate, so that the discharge hole 13 is communicated with the discharge pipeline 42, as Figure 8 shown. A one-way mechanism 43 is arranged in the discharge pipeline 42. The one-way mechanism 43 prevents external gas from entering the mixing cylinder 11. The one-way mechanism 43 ensures that only the mixture in the mixing cylinder 11 can be discharged, and external gas cannot enter the mixing cylinder 11. Thus, during the process of the two transverse movement cylinders 32 moving closer to each other, the raw materials that have been mixed in the mixing cylinder 11 are discharged; As Figure 7 and Figure 8 shown, the injection of liquid raw materials will be described in detail below; The liquid feeding mechanism 50 includes a liquid cylinder 51.

Then, the expansion ring 55 restricts the flow of the passing liquid raw materials, and thus the flow rate of the corresponding liquid raw materials. Furthermore, by controlling the expansion degree of the expansion rings 55 in multiple expansion sections 53, the input amount of multiple liquid raw materials is controlled to meet the requirements of mixing different liquid raw material ratios; When the liquid raw materials enter the storage cavity 58, the power mechanism IV is started. The power mechanism IV is preferably a servo motor. The output shaft of the power mechanism IV drives the rotating sphere 57 to rotate. During the rotation of the rotating sphere 57, the closed cavity 56 shields the storage cavity 58 to prevent the liquid in the storage cavity 58 from flowing out.

The telescopic end of the telescopic mechanism Ⅲ61 drives the sliding sleeve 65 and the bottom plate 63 to move, so that the sliding sleeve 65 and the bottom plate 63 extend into the mixing cylinder 11. The sliding sleeve 65 and the bottom plate 63 separate to put the solid raw materials into the mixing cylinder 11 and mix them through multiple elastic flaps 38. Furthermore, in order to ensure the vacuum state of the solid raw materials, the space between the sliding sleeve 65 and the bottom plate 63 is evacuated through the vacuum pipeline 66. And during the movement of the sliding sleeve 65 and the bottom plate 63, the sliding sleeve 65 seals the solid pipeline 44 to maintain the vacuum state, and then the solid raw materials are put into the mixing cylinder 11 in a vacuum state for mixing, reducing the generation of bubbles.
