The raw materials in the raw material bin 1 start to fall into the metering bin 21. At the same time, the three weight sensors 5 start to transmit weight information. When the raw materials in the metering bin 21 reach the specified weight, the screw conveyor motor 7 starts to work, and the power is transmitted to the auger 6 through the speed reducer 9, so that the auger 6 starts to work. The raw materials that meet the weight standard fall into the conveyor belt 11 through the feeding port 12.
