In addition, the raw materials used to produce such films are all petroleum products, which are non-renewable resources. Compared with synthetic polymer films, natural plant starch as a packaging film material has the advantages of being non-toxic, harmless, green and biodegradable. In the process of producing starch packaging film, the plant starch needs to be crushed and mixed with other reactants.

For example, during the stirring process, the shear force and vortex generated by the stirring blades or the stirring rod mainly act on the central area, making the fluid movement in the central area more violent, thereby improving the mixing efficiency. However, the movement of the fluid close to the side wall is hindered due to the limitation of the container wall, and the flow speed is slow, which easily forms a low flow rate area or a stagnant area. Therefore, the mixture close to the reactor or the side wall of the container is often easy to deposit, resulting in uneven mixing. Utility Model Content

The auxiliary drive assembly includes a plurality of fixed rods 30 fixedly connected to the lower end surface of the mounting sleeve 14 in an annular array, and a disc 31 is fixedly connected to the bottom end of the three fixed rods 30, and a through hole 311 is opened at the center of the disc 31, and the bottom end of the rotating shaft 16 passes through the through hole 311 vertically downward. In order to prevent the disc 31 from hindering the rotation of the rotating shaft 16, a bevel gear disc 32 is fixedly sleeved on the outer wall at the bottom of the outer wall of the disc 31, and the bevel gear 27 is meshed and connected with the bevel gear 27. During specific use, the rotating shaft 16 is driven to rotate by the driving motor 15, and the rotating shaft 16 drives the connecting rod 20 to rotate synchronously, and the connecting rod 20 drives the fixed cylinder 21 to rotate synchronously, and the stirring rod 26 connected to the inner side of the fixed cylinder 21 rotates synchronously, and the bevel gear 27 arranged at the top of the stirring rod 26 rotates around the bevel gear disc 32, so that the stirring rod 26 drives the stirring head 28 to rotate, and the fixed cylinder 21 is guided by the arranged ball head 22 and ball sleeve 24, and the fixed cylinder 21 rotates with the ball head 22 as the axis, so that the stirring head 28 can stir and mix the surrounding area in the mixing barrel 11, and the rotation of the stirring rod 26 further enhances the stirring effect, so that the starch and additives are mixed more fully.
