[0010] Furthermore, an air duct is arranged inside the installation box, a grille plate is fixedly installed on the inner side of the air duct, and a circle of air bags is fixedly installed on the inner side of the grille plate.

[0011] Furthermore, the grid plate is provided with a plurality of groups of fine holes.

[0012] Furthermore, the air inlet pipe, the airway, the fine hole and the airbag are connected to each other.

[0013] The beneficial effects of the utility model are as follows: by starting the telescopic device, the sealing plate is separated from the discharge port, so that the granulator starts to discharge materials, and by starting the motor to drive the stirring rod to rotate, the first discharge pipe is prevented from being blocked, and then by starting the inflation device, air enters the airbag through the air pipe, the airway and the pores, so that the airbag expands or contracts, the discharge diameter is adjusted, and the discharge speed is adjusted.
