The cylinder 1100 is arranged between the hopper 2000 and the transmission member 3000, and the cylinder 1100 includes a first contact surface 1110 and a second contact surface 1120 arranged opposite to each other. A bending area 1111 is arranged on the first contact surface 1110, and the bending area 1111 is bent in a direction away from the first contact surface 1110, so that the cylinder 1100 and the transmission member 3000 form a gathering-shaped accommodation space 1130. The accommodation space 1130 gathers in a direction close to the transmission member 3000. An opening 1181 is arranged on the cylinder 1100. The hopper 2000 is used to discharge powder into the cylinder 1100. The transmission member 3000 is used to drive the powder in the accommodating space 1130 to separate from the cylinder 1100 through the opening 1181, and to make the powder separated from the cylinder 1100 present a preset shape. In the process of discharging the powder in the hopper 2000 to the transmission member 3000, the cylinder 1100 defines a discharge channel for the powder, so as to effectively reduce the scattering of the powder in the process of discharging to the transmission member 3000, reduce the impact of the powder on the environment, reduce the waste of the powder, and improve the utilization rate of the powder. During the process of discharging the powder into the cylinder 1100, the gathered accommodating space 1130 can compress the powder, which helps to fix the shape of the powder, and through the cooperation of the transmission member 3000 and the opening 1181, the powder can be output in the preset shape, thereby reducing the scattering of the powder during the transmission process and further reducing the waste of the powder.

The second preset angle is equal to the first preset angle. The first bending segment 1111a connects the two second bending segments 1111b.

[0043] During the process of discharging the powder in the hopper 2000 to the conveyor 3000, the cylinder 1100 between the hopper 2000 and the conveyor 3000 defines a discharge channel for the powder, thereby effectively reducing the scattering of the powder during the discharge process to the conveyor 3000, reducing the impact of the scattered powder on the environment, and reducing the waste of the powder, improving the utilization rate of the powder. Moreover, during the process of discharging the powder into the cylinder 1100, the converging accommodation space 1130 of the cylinder 1100 can press the powder close to the conveyor 3000 to fix the shape of the powder. In addition, through the cooperation of the cylinder 1100, the opening 1181 on the cylinder 1100 and the conveyor 3000, the powder can be output in the preset shape. On the one hand, it can reduce the scattering of the powder during the transmission process, reduce the waste of the powder, and reduce the impact on the environment.
