When the upper clamping plate pair or the lower clamping plate pair is opened, the opening degree of the hose at the corresponding position is greater than 0; when the upper clamping plate pair or the lower clamping plate pair is closed, the opening degree of the hose at the corresponding position is equal to 0. The control unit 15 adjusts the opening degree of the hose 16 according to the charged amount in the weighing buffer bin 10 detected by the metering unit 5; when the charged amount exceeds a preset weight threshold, the control unit 15 reduces the opening degree of the hose through the upper and lower clamp pairs; when the charged amount reaches a preset target weight, the control unit 15 adjusts the opening degree of the hose 16 to 0 by the upper and lower jaw pairs. The weight threshold mentioned in the present invention may be a single value, or a plurality of weight thresholds may be set according to the actual charge weight. For example, if the target weight is 100g, the control unit decreases the opening degree of the hose when the charged amount reaches a weight threshold of 80g, and further decreases the opening degree of the hose when the charged amount reaches a weight threshold of 90g, so that the closer the charged amount is to the target weight, the smaller the opening degree of the hose, thereby improving the charging accuracy. The opening degree of the hose 16 is adjusted according to the fed amount in the weighing buffer bin 10 detected by the metering unit 5, so that the deviation between the actual fed amount and the preset target weight value caused by the fact that the feeding unit 2 cannot adjust the feeding speed according to the change of the material density or the particle size of the material particles can be avoided, and the metering accuracy and precision are improved.
