[0002] In order to improve the quality of plastic products, the raw materials are generally processed into plastic particles. Loose plastic particles are easily affected by moisture when exposed to the air. The chemical properties of plastic products made from damp plastic raw materials will be significantly reduced, thus affecting the quality of the products. Therefore, loose plastic particles need to be dried before being processed into plastic products. The commonly used method is to use a heat dissipation fan to send the heat of the heater directly into a pile of loose raw materials through a pipe to dry the raw materials.

The utility model sets a roller and a sleeve, and the motor drives the bevel gear to drive the bevel gear ring to rotate, so that the roller can be rotated, so that the plastic particles in the roller roll. At the same time, when the roller rotates, the driving wheel can be driven to rotate through the bracket and the threaded rod, and the driving wheel drives the rotating rod to rotate through the driven wheel to rotate the fan, so that airflow is generated at the sleeve, and the rolling plastic particles can be dried quickly by using the airflow to act on them.

[0004] Although the above technical solution can make the plastic particles tumble by rotating the drum, and use the airflow to act on the tumbling plastic particles to make them dry quickly, in actual operation, the hot airflow can only act on the surface of the raw material and cannot dry from the inside of the raw material, resulting in a decrease in its drying efficiency.
