The fixed seat 221 supports the rotating drum 232. The rotating drum 232 supports the inner rotating ring 231. The inner wall of the inner rotating ring 231 is meshed with the transmission gear 233. The transmission gear 233 rotates, driving the inner rotating ring 231 to rotate. The inner rotating ring 231 pushes the rotating drum 232 to rotate, and the rotating drum 232 feeds the material.

[0028] In this embodiment, a sleeve hole 2321 matching the inner rotating ring 231 is provided at the center of the rotating drum 232, a spiral bevel groove 2322 is provided on the inner wall of the sleeve hole 2321, and pushing protrusions 2311 are equidistantly provided on the upper surface of the inner rotating ring 231, and the pushing protrusions 2311 match the spiral bevel groove 2322.

A quantitative measuring groove 2323 is provided on the side wall of the rotating drum 232. When the quantitative measuring groove 2323 rotates to correspond to the feed port 222, the raw materials in the auxiliary material box 22 enter the quantitative measuring groove 2323. When the rotating drum 232 rotates and the quantitative measuring groove 2323 rotates to correspond to the discharge port 223, the raw materials in the quantitative measuring groove 2323 automatically fall from the discharge port 223 into the feed drum 11.

[0029] In this embodiment, an inner tooth 2312 matching the transmission gear 233 is provided on the inner wall of the inner rotating ring 231, and the inner tooth 2312 is meshed with the transmission gear 233.

[0030] In this embodiment, the stirring assembly 3 includes a feeding stirring shaft 31 and a reinforcing stirring shaft 32. The upper end of the feeding stirring shaft 31 is movably connected to the bottom of the main material box 21, and the lower end of the feeding stirring shaft 31 is connected to the driving base 12. A driving motor is provided in the driving base 12. The driving motor is connected to the feeding stirring shaft 31. The feeding stirring shaft 31 is driven to rotate by the driving motor. The reinforcing stirring shaft 32 is distributed in a ring shape in the mixing and stirring barrel 1.

[0031] In this embodiment, a sealing gear 311 is fixedly connected to the upper end of the feeding and stirring shaft 31, and the sealing gear 311 is meshed with the transmission gear 233. The sealing gear 311 is meshed with the small gear on the upper part of the transmission gear 233. The transmission gear 233 is driven to rotate by the rotation of the sealing gear 311.

The sealing gear 311 is in contact with the bottom of the main material box 21. When the fan-shaped outlet 3111 rotates to correspond to the leakage port 211, the raw materials in the main material box 21 enter the feeding barrel 11 through the leakage port 211 and the fan-shaped outlet 3111. When the fan-shaped outlet 3111 rotates to be misaligned with the leakage port 211, the leakage port 211 is blocked by the sealing gear 311, and the sealing gear 311 continues to rotate, so that intermittent feeding of the main material box 21 can be achieved. The size of the leakage port 211 and the fan-shaped outlet 3111 is fixed, so quantitative feeding can be achieved.

[0032] In this embodiment, the upper end of the enhanced stirring shaft 32 passes through the mixing drum 1, and a stirring motor 321 is provided at one end of the enhanced stirring shaft 32 outside the mixing drum 1. The rotation of the enhanced stirring shaft 32 is controlled by the stirring motor 321, and the stirring work can be performed independently after the feeding is completed.

[0033] Working process: according to the proportion of different raw materials, quantitative measuring slots 2323 of different sizes and matching leakage ports 211 are opened, and the corresponding materials are stored in the main material box 21 and the auxiliary material box 22. When stirring and mixing, the driving base 12 is turned on, and the feeding and stirring shaft 31 rotates under the control of the driving motor. The sealing gear 311 fits with the bottom of the main material box 21. When the fan-shaped outlet 3111 rotates to correspond to the leakage port 211, the raw materials in the main material box 21 enter the feeding barrel 11 through the leakage port 211 and the fan-shaped outlet 3111. At the same time, the transmission gear 233 is transmitted to the inner rotating ring 231, and the inner rotating ring 231 rotates to control the rotating barrel. 232 rotates, and the quantitative measuring groove 2323 rotates to correspond to the feed port 222. The raw materials in the auxiliary material box 22 enter the quantitative measuring groove 2323. The raw materials in the quantitative measuring groove 2323 automatically fall from the discharge port 223 to the feed barrel 11 under the rotation of the rotating drum 232. A small amount of equal amounts of multiple raw materials are preliminarily mixed in the feed barrel 11 and automatically slide into the mixing and stirring barrel 1. The feeding stirring shaft 31 and the enhanced stirring shaft 32 stir the raw materials at the same time. According to the required amount, the working time of the feeding stirring shaft 31 is controlled. When the feeding is completed, the feeding stirring shaft 31 is closed, and only the enhanced stirring shaft 32 is used to continue stirring to achieve sufficient mixing.

[0034] In summary, different raw materials are stored in the main material box 21 and the auxiliary material box 22 respectively. The main material box 21 realizes intermittent equal feeding through the rotating sealing gear 311. The sealing gear 311 is driven by the transmission gear 233 and the inner rotating ring 231 to control the rotating drum 232 to intermittently measure and feed raw materials from the auxiliary material box 22 in equal amounts. By controlling the size of different quantitative measuring grooves 2323 and the size of the leakage port 211, different raw materials can be fed in proportion. The dispersed feeding method is conducive to improving the mixing effect. The feeding can also be started and stopped at any time, which is flexible to use and avoids waste of raw materials.
