[0021] In the present embodiment, several feed ports 2 can be used for feeding at the same time, which improves the feeding speed, and the feeding is dispersed, which improves the screening speed. The bulk plate 21 below the feeding port 2 can further disperse the fallen plastic particles, so that the feed falling on the screening net 42 will not accumulate, thereby speeding up the screening. Starting the elevator 31 can drive the movable plate 33 to move up and down, thereby driving the baffle 34 to move up and down in the baffle engagement groove 11, closing the transverse hole 12 to prevent plastic particles from popping out during screening. When the screening net 42 needs to be replaced, the baffle 34 can be raised.
