[0034] Working principle: First, all the injection molding raw materials to be processed are put into the material box 3, and the raw materials in the material box 3 will fall into the fixed plate 4 from the bottom of the material box 3, allowing the raw materials to enter the gap between the fixed plate 7 and the partition plate 8, and then start the motor 5 to rotate the shaft 6, the fixed plate 7 and the partition plate 8, so that the raw materials are between the next set of fixed plates 7 and the partition plate 8, and finally the raw materials between the fixed plate 7 and the partition plate 8 will enter the feed hopper 14 from the lower end notch of the fixed plate 4, and enter the injection molding machine 1 for processing from the feed hopper 14.
