[0018] Turn the adjusting stud to make the adjusting swivel and the adjusting stud cooperate, move the adjusting plate, change the distance between the cutting tool blade and the adjusting plate, and thus change the size of the particles. After the power roller makes one end of multiple polyethylenes simultaneously abut against one side of the adjusting plate, the cutting tool moves down for cutting. The distance between the blade and the adjusting plate determines the size of the particles. At the same time, one end of the polyethylene simultaneously abuts against one side of the adjusting plate for cutting, so that the uniformity of the pelletizing size is guaranteed.

[0019] By designing a cooling mechanism, the polyethylene to be cut can be assisted in cooling down to prevent the polyethylene from sticking when being cut, while increasing the brittleness of the polyethylene so that it can be cut better.

[0020] The power air pump draws the air around the equipment into the serpentine air duct. The air is affected by the cold water in the water storage tank in the serpentine air duct, and the temperature of the air is reduced. The air is then sprayed onto the polyethylene through the jet nozzle connected to the air storage pipe to cool the polyethylene. BRIEF DESCRIPTION OF THE DRAWINGS
