案登録請求の範囲第１項記載の粉体成形機。[Claims for Utility Model Registration] (1) A pair of forming rolls 1 and 2 that are parallel to each other and rotate in opposite directions, a hopper 3 that supplies raw material powder between the forming rolls 1 and 2, and a hopper The hopper 3 has a vertical shaft 9 that rotates approximately on the center line of the hopper 3, and a raw material supply port 5 is provided at a location offset from the center position at the top of the hopper 3, and an exhaust port 6 is provided at the top of the hopper 3. In a powder molding machine, a feed screw 10 is provided at the lower end of the vertical shaft 9 to feed the raw material powder accumulated in the hopper 3 downward. A reverse feed screw 11 whose helical winding direction is opposite to that of the feed screw 10 is provided, and the rotation of this reverse feed screw 11 causes the raw material powder accumulated above the feed screw 10 to move upward. A powder molding machine characterized by pushing up. (2) The lower end of the reverse feed screw 11 forms an inclined upper surface c-d due to the repose angle α of the raw material powder accumulated in the hopper 3.
2. A powder molding machine according to claim 1, wherein the powder molding machine is set to be located at a lower position.
