[0034] (ii) When the mixing tank 2 is lifted and lowered back and forth, the rotating shaft 403 is driven to be lifted and lowered back and forth, and the rotating shaft 403 drives the gear 406 to reciprocate on the rack 402. Under the action of the rack 402, the gear 406 reciprocates. When the gear 406 rotates, it drives the rotating shaft 403 to rotate, and the rotating shaft 403 drives the stirring blade 404 to rotate, so as to stir the raw materials in the mixing tank 2.

[0035] (III) When the stirring is finished, the first motor 308 stops working, and the second motor 501 rotates in the opposite direction. The second motor 501 drives the protrusion 504 to separate from the pressure ring 506 through the rotating rod 503, so that the stirred material in the stirring tank 2 is discharged through the discharge pipe 505.
