Masterbatch is composed of three basic elements: pigment or dye, carrier and additive. It is an aggregate obtained by uniformly attaching an extraordinary amount of pigment to the resin. It can be called pigment concentrate, so its coloring power is higher than the pigment itself. When processing, a small amount of masterbatch is mixed with uncolored resin to achieve the coloring resin or product with the designed pigment concentration. The existing domestic masterbatch process is to use molecular wax, plastic particles or plastic powder and color powder or filler to stir at high speed and then put them into an extruder for extrusion and granulation. The extruder is used to mix and plasticize the granulation raw materials to form a plastic melt, and the extruder die head extrude plastic strips. After the plastic strips are cooled, the plastic strips are cut into plastic particles of a certain length by a plastic strip pelletizer. Usually, the particle sizes of masterbatches obtained after pelletizing vary greatly, and the masterbatches need to be transported to a screening device through a material guide port, and the masterbatches of different particle sizes are screened and collected by the screening device. Existing screening devices generally use a filter screen to screen the masterbatches, but in the screening process, the masterbatches are not in a completely regular shape, so they will get stuck in the sieve holes during the vibration screening process, causing the sieve holes to be blocked. When the number of blocked sieve holes is large, it is easy to affect the screening efficiency.
