The measuring cup holder 5 can adjust the depth of the filter screen 503 in the measuring hole 401 through the lifting action, thereby adjusting the material volume in the measuring hole 401. The frame 1 is also provided with an air blowing assembly 7 and a material receiving assembly 8. The air blowing assembly 7, the second vent 504, the first vent 502, the filter screen 503, the measuring hole 401 and the material receiving assembly 8 are connected in sequence so that the air blowing assembly 7 blows the material in the measuring hole 401 to the material receiving assembly 8. The rotary material metering and blowing device includes a main shaft 2, a rotary disk 4 and a measuring cup holder 5 circumferentially fixed to the main shaft 2. The rotary disk 4 has a metering through-hole 401. A measuring cup 501 is fixedly mounted on the measuring cup holder 5, passing through the metering through-hole 401. A first venting through-hole 502 is provided inside the measuring cup 501, and a filter screen 503 for intercepting material is fixedly mounted inside the first venting through-hole 502. A second venting through-hole 504 communicating with the first venting through-hole 502 is provided on the measuring cup holder 5.

[0024] Preferably, the turntable 4 has a sidewall 402 on its outer periphery, which encloses a material holding space, and a conical hopper 403 is provided in the middle of the turntable 4. In this embodiment, by providing a conical hopper 403 in the middle of the turntable 4, when the worker puts material into the turntable 4, the material will slide outward along the inclined surface of the conical hopper 403, preventing the material from accumulating in the center of the turntable 4.

[0025] Preferably, the frame 1 is provided with several sets of scrapers 101 that abut against the upper surface of the turntable 4 and electric stirring rod assemblies 102 for stirring materials. In this embodiment, the frame 1 is provided with scrapers 101 and electric stirring rod assemblies 102. During the rotation of the turntable 4, the scrapers 101 can guide the material from the inside of the turntable 4 to the metering through holes 401 located on the outer periphery, and the electric stirring rod assemblies 102 can stir and disperse the material to prevent the material from clumping and blocking the metering through holes 401.

The rotating bushing 608 rotates synchronously with the main shaft 2, and the upper end face of the third bearing 606 abuts against the shoulder of the rotating bushing 608, so that the axial movement of the lifting bearing seat 605 can drive the rotating bushing 608 and the measuring cup fixing seat 5 on it to move up and down relative to the main shaft 2. In other embodiments, the second drive mechanism 6 can also adopt components with reciprocating movement functions such as hydraulic cylinders and lead screw transmission mechanisms, and is not limited to this embodiment.

[0028] It should be noted that in this embodiment, the first drive mechanism 3 includes a servo motor and an indexer. The spindle 2 is connected to the output end of the indexer. The indexer converts the continuous rotational motion of the servo motor into precise, intermittent indexing motion of the output shaft, ensuring that each station can be accurately aligned with the actuator, namely the air blowing component 7 and the material receiving component 8, when it stops. This results in high operational reliability. In other embodiments, the first drive mechanism 3 can also adopt the form of a direct power connection between the servo motor and the spindle 2, and is not limited to this embodiment.

When the turntable 4 and the measuring cup fixing seat 5 rotate to the blowing station, the piston rod of the first telescopic cylinder 702 is in the extended state, and the air blowing nozzle 703 abuts against the lower end face of the measuring cup fixing seat 5. The gas blown by the air blowing nozzle 703 enters the metering through hole 401 through the second vent hole 504, the first vent hole 502, and the filter screen 503, and blows the material in the metering through hole 401 into the receiving assembly 8 to realize the quantitative blowing of the material.
