The material strips can be cut into granules after being cooled by a cooling water tank, the cooling water temperature is too low, the granules cut by the granulator generate stress whitening, and the plastic scraps are too much, so that the product quality is reduced; the cooling water temperature is too high, and the particles are easy to agglomerate after the material strips are too hot and cut into granules. Secondly, the cooling temperature difference of the material strips is large. When the produced plastic strip is cooled suddenly from a high temperature to the water temperature, a porous hollow is formed in the middle of the plastic strip, and a hole is formed in the middle of the particle after the plastic strip is cut into granules, so that the quality of the plastic particle is influenced.
