This utility model relates to the field of plastic recycling equipment, in particular to a plastic pelletizing device, which comprises a screw heating extruder and a screen-free die head. A hopper is arranged at the inlet of the first screw heating extruder, and the outlet is connected with the inlet of the first screen-free die head through a supercharger. A thermostat is arranged at the discharge port of the first screen-free die head, and the outlet of the first screen-free die head points to the inlet of the second screw heating extruder. The outlet of the second screw heating extruder is connected with the inlet of the second screen-free die head. On the basis of conventional screw extrusion, pressure boosting extrusion and constant temperature cooling for impurity removal are adopted, which is suitable for melting, recycling and purifying recycled plastics with many impurities. The masterbatch formed by pelletizing the produced plastic has high transparency and wear resistance, and is suitable as a raw material for subsequent modified plastic processing and production.
