[0022] Working principle: When using the plastic processing granulator, the rod-shaped material after cooling first enters the drying box 1 under the push of the driving wheel 12. When the rod-shaped material enters the drying box 1, it first contacts the wiping cotton 14, so that the wiping cotton 14 wipes most of the moisture on the surface of the rod-shaped material. Then the rod-shaped material continues to move forward. When the rod-shaped material passes through the fan 4, the high-speed airflow of the fan 4 blows away the residual moisture on the surface of the rod-shaped material. Then the rod-shaped material enters the granulation box 5 and contacts the rotating cutting blade 7 for cutting. After cutting, the plastic particles fall to the bottom of the granulation box 5 and gather on one side of the granulation box 5. Then, the sealing door 11 is opened to discharge the plastic particles. In the process of granulation, the sound insulation layer 6 can also reduce noise, thereby reducing the harm of noise to the workers.
