Most of the existing domestic waste is plastic waste, and many wastes need to be pretreated before burning the waste. In the process of garbage pretreatment, it is necessary to squeeze and pelletize the garbage to form garbage pellets, which is convenient for subsequent treatment such as garbage incineration.

Wherein, the extruding mechanism is arranged horizontally, and the feeding port 3 is arranged at one end of the extruding mechanism. The feed port 3 is funnel-shaped, the upper end of which is open to receive the material conveyed from the upstream, and the lower end is connected with the extruding mechanism, and the material is conveyed into the extruding mechanism through the lower end. The extruding mechanism extrudes the garbage materials delivered by the feed port 3 to facilitate subsequent material cutting.

A material outlet 4 is provided at the other end of the material preparation device opposite to the material inlet 3 , and the cutter assembly 1 provided in Embodiment 1 is provided at the material outlet 4 .

The screw housing 52 is erected on the support 2; the output shaft of the reducer 53 is connected to one end of the screw 51 close to the feed port 3, so that the screw 51 rotates in the screw housing 52; The pitch gradually decreases. Moreover, along the direction from the feed port 3 to the discharge port 4, the diameter of the screw 51 preferably also has a tendency to increase.

Specifically, the extruding mechanism is cylindrical and arranged laterally. The screw shell 52 is a hollow cylinder, the top of one end is connected to the feed port 3 , and the other end is connected to the discharge port 4 . Garbage materials are conveyed into the screw shell 52 by the feed port 3, and are formed by the extrusion of the screw 51, and when they reach the extrusion mechanism provided with the discharge port 4, the formed garbage materials touch the cutter assembly 1, three The cutting blade 11 and the auxiliary cutting blade 13 cut the material into pellets to realize the pelletizing of the material, and then discharge it from the discharge port 4 .

Wherein, in order to realize the physical compression of the waste material and make it shape, the pitch of the screw 51, that is, the distance between the helical blades on the screw 51 is gradually reduced in the direction from the feed port 3 to the discharge port 4. As the reducer 53 drives the screw 51 to rotate, the garbage materials between the helical blades are continuously pushed forward. As the distance between the helical blades gradually decreases, the garbage materials are gradually compressed and compacted, and the density is getting higher and higher. big.
