The inner wall of the transmission member 4 close to the center is fixedly connected to the outer wall of the driving member 2 close to the top. The inner wall of the transmission member 4 far from the center is fixedly connected to the outer wall of the strengthening stirring member 5 close to the top. The transmission member 4 includes a first gear 401, a second gear 402, a gear ring 403 and a limiting block 404.

[0022] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the raw material bin 1 is composed of a bin body 101, a bin cover 102 and fastening bolts 103. The top of the bin body 101 is fixedly connected to the bottom of the bin cover 102 through the fastening bolts 103. An outlet is provided at the bottom of the bin body 101, and a rotating groove is provided on the inner wall at the center of the bin cover 102.

When the second gear 402 rotates, it drives the short stirring roller 502 to rotate through the third rotating shaft 501. When the first rotating shaft 203 rotates, it drives the second rotating shaft 301 to rotate synchronously. The spiral blade 302 rotates under the drive of the second rotating shaft 301, and pushes the material out of the discharge pipe 303, preventing the raw material from blocking the discharge pipe 303. The short stirring roller 502 and the long stirring roller 204 form a hierarchical stirring, which helps to disperse and homogenize the mixture, ensuring that the materials are evenly mixed at different heights, enabling the materials with different viscosities to be discharged smoothly. While the first rotating shaft 203 rotates and stirs, it drives the scraping strip 205 to move in a circular motion around the axis of the first rotating shaft 203, and further drives the scraping blade 206 to move in a circular motion on the wall of the bin body 101.
