The inner wall of the discharge box 41 is rotatably connected to a transmission screw 46, and the transmission screw 46 is threadedly connected to the inner wall of the moving rod 48. A motor 44 is fixedly connected to the surface of one side of the discharge box 41, and the output end of the motor 44 is transmission-connected to the transmission screw 46 through a belt. The motor 44 cooperates with the belt to drive the transmission screw 46 to rotate, thereby controlling the movement of the moving rod 48 and the flipping rod 49, flipping the plastic particles on the conveyor belt 3, and facilitating the plastic particles to be evenly heated and dried.

[0026] Specifically, a push rod 410 is fixedly connected to the surface of the moving rod 48 close to the material box 41 , and there are multiple push rods 410 . Two baffles 45 are fixedly connected to the inner wall of the oven body 1 .

[0027] In this embodiment, the push rod 410 can push the plastic particles in the unloading box 41 to facilitate unloading.

[0028] Specifically, two limit plates 47 are fixedly connected to the surface of the water filter plate 42 , and the limit plates 47 can guide the plastic particles on the water filter plate 42 to the conveyor belt 3 , and the baffle 45 can intercept the plastic particles on the conveyor belt 3 .
