[0024] The rotating shaft 4 is driven to rotate by the driving motor group 3, and then the rotating shaft 4 rotates around the fixed rod 16, and the two groups of movable rods are driven to rotate by the linkage component 11, and the spiral blade 10 is used to flip the raw materials at the bottom of the reaction tank 1 to the uppermost layer through the fixed tube 8, so as to avoid the resin raw materials from being unable to flow and stir quickly due to poor fluidity. At the same time, the driving component 15 drives the stirring shaft 13 and the stirring blade 14 to mix and stir the raw materials from the inside of the raw materials, thereby increasing the fluidity of the raw materials and ensuring that the resin raw materials are evenly stirred under the drive of the driving motor group 3, which is conducive to the reaction synthesis of the silicone resin.

[0025] A cavity is opened at the bottom of the rotating shaft 4, and a fixing rod 16 is fixed at the bottom of the inner cavity of the reaction tank 1. The top of the fixing rod 16 passes through the fixing frame 5 and extends to the top of the inner cavity of the cavity.

The driving motor group 3 is utilized to drive the rotating shaft 4 to rotate around the fixing rod 16, thereby realizing relative rotation between the fixing rod 16 and the rotating shaft 4, and providing driving force for the movable shaft 9 and the stirring shaft 13.
