The spring 13 will always have a force pressing the slide bar 9 in the direction of the bulk material tray 4 to ensure that the brush 11 is tightly attached to the bulk material tray 4. When the bulk material tray 4 rotates, the brush 11 can clean the outer wall of the bulk material tray 4 to prevent the powder from adhering to the bulk material tray 4 due to moisture.

[0022] like Figure 2 The rotary drive device 6 includes a motor 14, which is arranged on the hanging plate 5. A bevel gear 15 is provided at the output end of the motor 14.
