粉体移送装置４へ落下する。According to the powder supply device of the embodiment, the screw shaft 4 of the powder transfer device 4 is driven by a motor (not shown).
0 is rotated in the transfer direction, and the vibrator 2 is operated to supply a measured amount of powder into the powder supply hopper 1. The powder falls smoothly to the upstream side of the powder transfer device 4 by the vibration of the powder supply hopper 1 and is supplied from the discharge port 41 to a mixer (not shown), where the powder is mixed or kneaded with the liquid agent. The vibration of vibrator 2 is applied to side wall 1
0 to the opposing side wall 11, and the vibration of the opposing side wall 11 of the hopper 1 becomes larger than in the conventional powder feeder, so that the powder is prevented from being crosslinked on the side of the opposing side wall 11. . Since the opposing side wall 11 is formed vertically, even if the vibration force or the amplitude of the vibrator 2 is relatively small, the powder can be smoothly dropped on the side wall 11. Further, since the resonance bar 3 is attached along the transfer direction of the powder transfer device 4, the powder charged into the hopper 1 falls to the powder transfer device 4 more efficiently.
