After that, the upper blanking plate 11 is opened under the action of the upper blanking cylinder 12, so that the material in the primary hopper falls into the secondary hopper composed of the front baffle 5, the right baffle 24 and the left baffle 25. At this time, the front plate 22 and the rear plate 26 are in a closed state under the action of the two lower blanking cylinders 19.
