PROBLEM TO BE SOLVED: To provide a raw material supply device capable of catching an auxiliary raw material which cannot be easily caught in a main raw material properly.SOLUTION: A main raw material passage 13 for a main raw material M and an auxiliary raw material passage 23 for an auxiliary raw material N are joined in a fork-state, the main raw material passage 13 and the auxiliary raw material passage 23 are set to a downgrade so that the respective raw materials M, N can flow down by self-weight. The raw materials are flown down by self-weight toward a molding machine A via a raw material introduction port 5, a hindrance plate 15 is suspended from an upper part of a downstream end opening 13a downward, in the vicinity of the downstream end opening 13a on the main raw material passage 13, and a main raw material passage space S is formed at least between a side 15b of the hindrance plate 15 and the downstream end opening 13a, a mixing screw 9 which rotates so as to push the raw materials M, N to the hindrance plate 15 is disposed right under a lower end 15c of the hindrance plate 15, and the mixing screw 9 is disposed so as to incline downward toward the hindrance plate 15 side, and crosses the hindrance plate 15 by solid cross, in plan view.SELECTED DRAWING: Figure 1 |
