[0040] In this embodiment, the silicone rubber kneading tank 3 is provided with a feed pipe, and the extrusion bin 18 is provided with a discharge pipe, so as to facilitate the discharge of the raw materials after mixing.

[0041] Working principle: When in use, firstly, the raw materials are transported into the silicone rubber kneading tank 3 through the feed pipe on the silicone rubber kneading tank 3, and then the gear 14 is driven by the motor 13 to rotate and transmit with the gear ring 15, and at the same time, the gear ring 15 drives the multiple stirring rods 11 to rotate through the sleeve 10, so as to achieve the effect of mixing and stirring the raw materials;

[0042] After the raw material mixing is completed, the round rod 4 is driven by the second motor 16 to rotate a certain angle on the sleeve 10 and the silicone rubber kneading tank 3, and the round rod 4 drives the fixed plate 5 to rotate a certain angle synchronously.

[0043] Afterwards, the motor 2 16 continues to drive the round rod 4, so that the round rod 4 drives the fixed plate 5 and the U-shaped plate 9 to rotate synchronously, so that the scraper on the U-shaped plate 9 cleans the inner wall of the silicone rubber kneading tank 3, and at the same time, the corresponding fixed plate 5 drives the partition plate 8 to rotate through the transmission of the telescopic plate 6 and the movable plate 7, so as to further clean the inner wall of the silicone rubber kneading tank 3. In this process, when the scraper moves to the bottom of the silicone rubber kneading tank 3, the raw materials on the scraper pass through the discharge port and the feed port on the extrusion bin 18 under the action of centrifugal force and enter the extrusion bin 18, so as to discharge the scraped raw materials; when the partition plate 8 moves to the bottom of the silicone rubber kneading tank 3, the two telescopic plates 6 are restored to their original state by the action of the two springs 21, and at the same time, the partition plate 8 is engaged with the discharge port through the transmission of the movable plate 7, so as to achieve the effect of sealing the discharge port, so as to prevent the raw materials from entering the extrusion bin 18 during the stirring process.
