A sieve 41 is provided on the upper surface of the sieve frame 4. Baffles 42 are provided on both sides of the sieve 41. The slope outlet of the sieve frame 4 corresponds to the material receiving funnel 5. Through the primary screening of the sieve 41 on the sieve frame 4, the finest plastic additives enter the cavity inside the sieve frame 4 and are collected. The slightly coarser plastic additives enter the material receiving bucket 6 from the material receiving funnel 5 along the slope of the sieve for secondary screening and collection. The pad between the material receiving bucket 6 and the workbench 1 makes the material receiving bucket 6 more stable and firm.

[0023] Figure 4 , Figure 5The internal structure diagram of the screening device for processing plastic additives is shown, wherein the screening box 2 is rotated by the screening barrel 23 to perform centrifugal motion, thereby further screening and classifying the coarse material.
