[0028] The second connecting component includes a second solenoid valve (not shown in the figure); the second solenoid valve is installed on the baffle 501 to open or close the third chamber 30.

[0029] Specifically, a connecting port 502 is provided in the baffle 501, and the second solenoid valve is installed in the connecting port 502; when working, the bottom of the third chamber 30 is connected to the feed port of the injection molding machine, and the material enters the injection molding machine through the first chamber 10, the connecting pipe 401 and the second solenoid valve in turn; when it is necessary to quantitatively control the total amount of material discharge, the first solenoid valve and the second solenoid valve are closed, and the first driving unit drives the baffle 501 to move vertically in the third chamber 30 to control the capacity of the third chamber 30. When the capacity of the third chamber 30 is within the preset capacity, the first solenoid valve is opened to allow the material to enter the third chamber 30 through the connecting pipe 401. When the third chamber 30 is filled with material, the first solenoid valve is closed and the second solenoid valve is opened, thereby effectively controlling the quantitative input of the material.
