The top projection of the sliding plate 12 covers the top projection of the feed port. When the feed port 13 on the sliding plate 12 coincides with the vertical positions of the discharge port and the feed port, the material in the feed box 2 is transported into the kneading device body 1. When other parts of the sliding plate 12 are misaligned with the vertical positions of the discharge port and the feed port, the material is stopped from being fed into the kneading device body 1.
