In this embodiment, the number of main blanking ports is twelve, that is, six main blanking ports are evenly arranged on both sides; the vibration motor 303 is installed on the side of the main hopper 301. In this embodiment, the number of vibration motors 303 is two, which are respectively arranged on both sides of the main hopper 301. The vibration motor is only used to dredge the raw materials between the main hopper 301 and the intermediate buffer hopper 401, and is not used for direct blanking.

[0027] The intermediate buffer bin mechanism 40 includes an intermediate buffer hopper 401, and the intermediate buffer hopper 401 is installed on the frame 10 through a vibrating member, and the vibrating member is a linear vibrator 402; in this embodiment, the number of intermediate buffer hoppers 401 is twelve, and each is separately controlled by the linear vibrator 402 to act. The raw materials are conveyed to the secondary bin 501 through the linear vibrator 402; one end of the intermediate buffer hopper 401 is located below the main blanking port, and the other end of the intermediate buffer hopper 401 has a discharge notch.

[0028] The secondary blanking bin 50 mechanism includes a secondary bin 501, a screw conveyor shaft 503, and a blanking pipe 504. The shape of the blanking pipe 504 is L-shaped. The secondary bin 501 is installed on the frame 10, and the secondary bin 501 is located below the discharge notch. One end of the blanking pipe 504 is connected to the lower part of the secondary bin 501. The screw conveyor shaft 503 is horizontally rotatably installed on the secondary bin 501. The screw conveyor shaft 503 extends out of the secondary bin 501 and is located inside the blanking pipe 504. The other end of the screw conveyor shaft 503 extends out of the secondary bin 501 and is connected to a driving motor 507 that can make it rotate. In this embodiment, the screw conveyor shaft 503 is driven by an independently operating servo system for blanking.
