The purpose of the present invention is to provide a kind of plastic part processing unit (plant), with mixed uniformly simultaneously to plastic pellet,
Improve the efficiency of plastic pellet drying.
In order to achieve the above objectives, base case of the invention is as follows：
Plastic part processing unit (plant) includes rack, rotating turret, drying cylinder and driving motor, and rotating turret is rotatably connected on rack
On, the rotation of driving motor powered rotatable frame, rotating turret is set in outside drying cylinder, and drying cylinder is slidably connected with rotating turret, is done
Dry cylinder and rotating turret are equipped with mutually matched spiral groove and spiral ridge, and when drying cylinder is slided along rotating turret, drying cylinder is by phase
Rotating turret is rotated；First piston is equipped in the drying cylinder, drying cylinder is divided into drying chamber and pressure chamber by first piston, the
One piston is fixedly connected on rotating turret；First pipe and second pipe are fixed on first piston；It is equipped with and fixes in pressure chamber
