[0026] A stirring mechanism is installed inside the cylinder 2, which is used to stir the raw materials;

[0027] The extraction mechanism is installed on the cylinder 2. The extraction mechanism is used to extract the raw material with low fluidity at the bottom of the cylinder 2 and re-inject it from the top.

[0028] The stirring mechanism includes a crossbeam 4 bolted to the upper part of the inner wall of the cylinder 2, two servo motors 5 fixed to the crossbeam 4, the two servo motors 5 being symmetrically arranged, and two stirring frames 6 rotatably connected to the crossbeam 4. The tops of the two stirring frames 6 are respectively fixed to the output shafts of the two servo motors 5.

[0029] The extraction mechanism includes two housings 7 welded to the lower sides of the cylinder 2, which cover the two diversion ports at the lower part of the cylinder 2; two extraction pipes 8 fixed to the two housings 7, each with an inlet at the bottom; two return pipes 9 fixed between the two extraction pipes 8 and the cylinder 2, which are inclined and communicate with the cylinder 2 through the extraction pipes 8; two servo motors 10 fixed to the top of the two extraction pipes 8; two spiral conveyor frames 11 rotatably connected between the two extraction pipes 8 and the two housings 7, with the tops of the two spiral conveyor frames 11 fixed to the output shafts of the two servo motors 10; and opening and closing components mounted on the cylinder 2, housings 7, and spiral conveyor frames 11.

[0030] The opening and closing assembly comprises two gear wheels I 12 fixed respectively at the lower ends of the two spiral feeders 11, two rotating shafts I 13 rotatably connected respectively to the two housings 7, two gear wheels II 14 fixed respectively to the two rotating shafts I 13, the two gear wheels I 12 meshing respectively with the two gear wheels II 14, two rotating shafts II 15 rotatably connected to the barrel 2, two transmission assemblies 16 arranged respectively between the two rotating shafts I 13 and the two rotating shafts II 15, the spiral feeders 11 being driven to rotate by the gear wheels I 12 and the gear wheels II 14, and then driving the rotating shafts I 13 to rotate through the transmission assemblies 16, two gear wheels III 17 fixed respectively to the two rotating shafts II 15, the gear wheels III 17 being cogless gear wheels, two sliding frames 18 slidably connected to the barrel 2, the lower portions of the two sliding frames 18 covering respectively two shunt ports of the barrel 2, two sets of return springs 181 arranged respectively between the two sliding frames 18 and the barrel 2, two racks 19 fixed respectively to the upper portions of the two sliding frames 18, the two racks 19 meshing respectively with the two gear wheels III 17, the rotating shafts II 15 driving the sliding frames 18 to move intermittently through the gear wheels III 17 and the racks 19, and then controlling the shunt ports of the barrel 2 to open and close intermittently.

[0031] The transmission assembly 16 comprises a driving wheel fixed to the rotating shaft I 13, a driven wheel fixed to the rotating shaft II 15, and a transmission belt wound between the driving wheel and the driven wheel.

[0032] Initially, the staff pours appropriate amounts of raw materials (warm water, flour, eggs, milk, white sugar, and various additives, etc.) into the cylinder 2 according to the proportions. The height of the raw materials poured in should not exceed the lowest point of the connection between the return pipe 9 and the cylinder 2. After the raw materials are added, the staff starts two servo motors 1-5. The output shaft of servo motor 1-5 drives the stirring rack 6 to rotate. The stirring rack 6 rotates to disperse and mix the raw materials. When the raw materials are stirred to a certain fluidity, the staff starts two servo motors 2-10. The output shaft of servo motor 2-10 drives the spiral conveyor rack 11 to rotate. The rotation of spiral conveyor rack 11 drives gear 1-12 to rotate. Gear 1-12 drives gear 2-14 to rotate. Gear 2-14 drives shaft 1-13 to rotate. Shaft 1-13 drives shaft 2-15 to rotate through transmission component 16. Shaft 2-15 drives gear 3-17 to rotate. Gear 3-17 drives the sliding frame 18 to move upward through rack 19. The return spring 181 is stretched, and the sliding frame 18 moves upward, exposing part of the diversion port of the cylinder 2. Gear 17 continues to rotate and disengages from rack 19. Return spring 181 rebounds and drives sliding frame 18 and rack 19 to move downwards to reset. Gear 17 continues to rotate, causing sliding frame 18 to intermittently open and close the diversion port of cylinder 2. The raw material with poor flowability at the bottom of cylinder 2 intermittently enters shell 7 through the diversion port of cylinder 2. Spiral conveyor 11 conveys the raw material entering shell 7 upwards and returns it to the upper layer of raw material through return pipe 9. Through the above operation, it is convenient to extract the raw material with poor flowability at the bottom of cylinder 2 and return it to the upper layer of raw material, which speeds up the mixing speed of raw material and improves stirring efficiency. After stirring, the operator places the container receiving the raw material under the bottom cover 3, turns off servo motor 5, opens the bottom cover 3, and lets the raw material flow into the container. Servo motor 10 continues to work for a period of time until the raw material is discharged and then turns off. Finally, the operator uses clean water to rinse the part of the device that came into contact with the raw material. After rinsing, the bottom cover 3 is put back on the bottom of cylinder 2 for easy operation next time.

[0033] Example 2: Based on Example 1, such as Figures 1-2 As shown, the lower part of the inner wall of the shell 7 is arranged in a converging manner, which enables the raw material to flow quickly to the feed inlet of the extraction pipe 8.

[0034] The converging arrangement of the inner wall of the shell 7 allows the raw materials to flow more smoothly to the feed inlet of the extraction pipe 8, thereby improving the extraction efficiency of the spiral conveyor 11.

The above description of the examples is only used to help understand the method of the application and its core idea; meanwhile, for those skilled in the art, according to the idea of the application, the specific implementation modes and application ranges will have changes, and the above description should not be understood as a limitation on the application.
