Document Type and Number:
WIPO Patent Application WO/2017/163628
Kind Code:
A1
Abstract:
The purpose of the present invention is to enable a fixed amount of powder to be dispensed in a uniformly spreading manner. Provided is a powder dispensing device comprising: a chute section 50 having a sloped flat surface 511 tilted relative to a horizontal plane, the sloped flat surface 511 allowing powder P to flow down along the sloped flat surface and dispensing the powder P downward from the lower end of the sloped flat surface; a vibration section 55 for vibrating the chute section; a first restriction section 56 having a facing portion which, in a width direction parallel to the sloped flat surface and being horizontal, faces the sloped flat surface with a constant first gap therebetween, and which forms a slit-like opening A1 between the facing portion and the sloped flat surface, the opening A1 having a longitudinal direction aligned with the width direction, the first restriction section 56 also having a barrier wall portion extending upward from the facing portion, the first restriction section 56 allowing powder accumulated between the barrier wall portion and the sloped flat surface to flow down from the opening along the sloped flat surface; and a second restriction section 57 which, between the portion of the sloped flat surface which faces the first restriction section and the lower end of the sloped flat surface, faces the sloped flat surface with a second gap therebetween, the second gap being constant in the width direction and being smaller than the first gap, the second restriction section 57 forming a slit-like opening A2 between the second restriction section 57 and the sloped flat surface, the opening A2 having a longitudinal direction aligned with the width direction.
