Simultaneously, the stirring mechanism 2 adopts a plurality of stirring shafts 6 to stir, the stirring dead angle is less, the flowing of the raw materials is more disordered in the stirring process, and the materials can be rapidly and uniformly mixed conveniently. In addition, in the lifting process of the stirring shaft 6 of the stirring mechanism 2, only the stirring shaft 6 needs to be driven independently to lift, the power part and the transmission structure of the stirring mechanism do not need to be driven to lift, the flexibility is high, the lifting load is low, and the structure is very exquisite and compact.
On the basis, in order to further improve the stirring effect of the stirring mechanism 2, each stirring shaft 6 can also vibrate alternately in the vertical direction, so as to drive the stirring head 7 at the lower end of the stirring shaft to lift alternately, thereby improving the overall turbulence and finally improving the stirring uniformity.
