The utility model discloses further set up to: two limiting plates for preventing plastic particles from sliding off from two sides of the limiting plates are fixedly connected to two sides of the top of the screening plate.

Through adopting above-mentioned technical scheme, can prevent plastic granules from the both sides landing of limiting plate through setting up the limiting plate.

The utility model discloses further set up to: the top of the limiting plate is fixedly connected with a plurality of blocking rods, the axes of the blocking rods are perpendicular to the screening plate, and the blocking rods and the screening holes are distributed in a staggered mode along the inclined direction of the screening plate.

Through adopting above-mentioned technical scheme, block the speed that the pole can slow down the plastic granules whereabouts through the setting for the plastic granules that accord with specification size can be more abundant drop to the conveyer belt.

To sum up, the utility model discloses compare and have following beneficial effect in prior art: the utility model discloses when carrying out kibbling to plastic granules, plastic granules after smashing falls on the screening board, the screening hole that the plastic granules that accords with specification size passed the screening board falls to the conveyer belt top, then by conveyer belt conveying away, the plastic granules that is not conform to specification size then falls into in the middle of the circulation is fought along the screening board under the effect of self gravity, then pass the unloading pipe in the middle of falling into the circulating pipe from the circulation fill, then blow the plastic granules under the effect of fan and enter into in the middle of the inlet pipe, then fall into in the middle of the feeder hopper of rubbing crusher in the inlet pipe, smash once more, make the plastic granules who carries out the hot melt basis in the middle of the extruder all accord with specification size, the production quality of masterbatch has been improved.
