[0026] Powder is poured into the feed hopper 204. Some of the powder falls into the cavity of the limiting groove 203 on the upper part of the limiting column 202. Then the limiting column 202 is rotated, and the powder in the limiting groove 203 is moved to the lower opening of the feed box 201 by the limiting column 202, so that the powder can fall into the drain pipe 11.
