[0036] A first connecting member 212 is fixedly installed on the output shaft of the electric push rod 211, and first extension arms 213 are movably installed on both sides of the bottom of the first connecting member 212, and a second extension arm 214 is movably installed on the bottom of the first extension arm 213, and a second connecting member 215 is movably installed on the bottom of the second extension arm 214, and a rotating shaft 216 is fixedly installed on the bottom of the second connecting member 215, and the rotating shaft 216 is movably installed at the bottom of the inner cavity of the blending box 21, and a first stirring blade 217 is fixedly installed on the outer surface of the rotating shaft 216, and a second stirring blade 218 is fixedly installed on the surface of the first extension arm 213 on one side and the second extension arm 214 on one side;

[0037] The scraping module includes a scraper 219 . There are two scrapers 219 , which are fixedly mounted on the surface of a first extension arm 213 and a second extension arm 214 , respectively. A third stirring blade 220 is fixedly mounted on the surface of the scraper 219 .

[0038] Specifically, when in use, the user first needs to start the first servo motor 2 to drive the blending box 21 to flip, so that the blending box 21 is tilted, and then open the loading and unloading port 22 to load the material, and close the loading and unloading port 22 after loading the material, and then start the second servo motor 24, so that the second servo motor 24 drives the first rotating wheel 25 to rotate, and the first rotating wheel 25 can drive the transmission belt 26, so that the transmission belt 26 drives the second rotating wheel 27 to rotate;

[0041] Example 2: Please refer to Figure 1 and Figure 6The first rotating wheel 25 is provided with a flip assembly, which includes a first toggle member 3, which is fixedly mounted in the middle of the first rotating wheel 25, and a first gear 31 is fixedly mounted on one end of the first toggle member 3 away from the first rotating wheel 25, a second gear 32 is meshed with one side of the first gear 31, and a second toggle member 34 is fixedly mounted in the middle of the second gear 32, and a driving groove 33 adapted to the first gear 31 and the second gear 32 is opened inside the mixing box 21;

[0042] The driving groove 33 is spaced from the inner cavity of the blending box 21, and the blending box 21 and the first toggle member 3, and the blending box 21 and the second toggle member 34 are in active contact with each other;

[0043] A sealing ring is provided between the driving groove 33 and the inner cavity of the mixing box 21, and a toggle groove is provided on the outer circumference of the first toggle member 3 and the second toggle member 34, and the first stirring blade 217 is located below the first toggle member 3 and the second toggle member 34;

[0044] The mixing box 21 is provided with a blowing assembly, which includes an air channel 4, which is opened inside the mixing box 21, a one-way valve 41 is fixedly installed on the lower side of the air channel 4, a piston 42 is movably installed inside the air channel 4, and a piston rod 43 is fixedly installed in the middle of the piston 42;

[0045] The piston rod 43 is in active contact with the air passage 4, a touch plate 44 is fixedly mounted on the top of the piston rod 43, a return spring 45 is arranged on the outer peripheral side of the piston rod 43, and the return spring 45 is located between the touch plate 44 and the blending box 21, a driving member 46 is fixedly mounted on the middle of the second rotating wheel 27 away from the worm 28, and a clearance groove 47 adapted to the driving member 46 is provided inside the mounting frame 11;

[0046] A sealing ring is provided at the movable contact point between the air channel 4 and the piston rod 43, and the one-way valve 41 is arranged to be inclined upward.

[0047] On the basis of Example 1, when the first rotating wheel 25 rotates, it can drive the first toggle member 3 to rotate, and when the first toggle member 3 rotates, the first gear 31 can be driven to rotate the second gear 32, so that the second gear 32 drives the second toggle member 34 to rotate.

[0048] Furthermore, when the second rotating wheel 27 rotates, it can drive the driving member 46 to rotate, so that the driving member 46 touches the touch plate 44. At this time, the driving member 46 drives the touch plate 44 to move downward, so that the touch plate 44 drives the piston rod 43 to move downward. When the piston rod 43 moves downward, it drives the piston 42 to move downward, and the air in the airway 4 is squeezed into the inner cavity of the blending box 21 through the one-way valve 41, and then the raw materials on the lower side of the inner cavity of the blending box 21 are blown to the upper side, further increasing the mixing speed of the raw materials and improving the consistency and uniformity of the raw materials.

[0049] During the stirring process, the first servo motor 2 can be started to drive the blending box 21 to swing left and right, thereby further improving the mixing efficiency. After the blending is completed, the first servo motor 2 needs to be started again so that the upper and lower material ports 22 face the collecting box 5 and are opened, so that the raw materials can enter the collecting box 5 and be collected. The upper and lower material ports 22 are close to the collecting box 5, and the distance between the two is small, which can reduce the flying of raw materials.

[0051] S1: First, the raw materials are placed in the inner cavity of the blending box 21, and the second servo motor 24 is started to drive the first extension arm 213, the second extension arm 214 and the first stirring blade 217 to rotate, thereby achieving a stirring operation;

[0052] S2: When the second servo motor 24 is started, it drives the first shifting member 3 to rotate, so that the first shifting member 3 drives the first gear 31 to rotate, and the second gear 32 drives the second shifting member 34 to rotate, so that the raw materials on the lower side of the inner cavity of the blending box 21 are turned over;

[0053] S3: When the second wheel 27 rotates, it can drive the driving member 46 to rotate, and cooperate with the return spring 45 to drive the piston 42, so that the gas in the airway 4 is blown out from the one-way valve 41, and further blows the raw materials on the lower side of the inner cavity of the blending box 21.
