The screw rotated a few times according to the amount of powder to be filled, so as to reach the filling amount. Some powders with particles cannot be filled because the particles are damaged by the extrusion during the screw rotation process. Or the filling screw with light powder cannot achieve accurate filling volume. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] As shown in the figure, the embodiment of the utility model discloses an airflow type powder filling device, comprising a powder filling barrel 1, a powder stirring hopper 2 and a filling head 3, the powder filling barrel 1 is arranged above the powder stirring hopper 2, and the filling head 3 is arranged below the powder stirring hopper 2. As shown in the figure, a funnel 101 is provided at the bottom of the powder filling barrel 1, and the funnel 101 is connected to the powder receiving part 201 at the top of the powder stirring hopper 2, so that the powder enters the powder stirring hopper 2 from the powder filling barrel 1, and the powder in the powder stirring hopper 2 falls into the filling head 3 from the bottom after being stirred.

[0021] A plurality of rows of dispensing holes 4 are provided on the curved surface of the dispensing head, the axis of the dispensing hole 4 is perpendicular to the axis of the dispensing head 3, a piston cylinder 5 is provided in the dispensing hole 4, a piston 6 is installed at the output end of the piston cylinder 5, a vacuum disk 7 is installed on the end face of the dispensing head 3, the vacuum disk 7 is coaxial with the dispensing head 3, a vacuum pipeline 8 and a compressed air pipeline 9 are provided at the vacuum disk 7, the end face of the vacuum disk 7 facing the dispensing head 3 is provided with corresponding vacuum air holes and compressed air holes, and the dispensing hole 4 of the dispensing head 3 is provided with a connecting port 10.

[0022] The vacuum pipeline 8 moves the piston 6 of the piston cylinder 5 in the opposite direction, and the piston 6 forms a vacuum at the front end of the dispensing hole 4 to absorb the powder. By controlling the position of the vacuum pipeline 8 and the piston 6, the amount of powder absorbed can be accurately achieved. The dispensing head 3 rotates, and when the powder reaches the bottom, the compressed air pipeline 9 is ventilated to blow the powder out from the piston, and the powder falls into the bottle 16.
