Grinding module of dry ice jet cleaning machine

The utility model discloses a grinding module of a dry ice jet cleaning machine. Including a body, the body is provided with a channel allowing dry ice blocks to pass through, and a feeding port and adischarging port are formed in the body. A grinding wheel for grinding dry ice cubes is rotationally connected into the channel; the grinding wheels are symmetrically arranged, and pressing strips used for crushing dry ice blocks are arranged between the adjacent grinding wheels. The rotation directions of the adjacent grinding wheels are opposite, and the grinding wheels rotate towards the direction of the pressing strip; therefore, the pressing strip is arranged; two parts for grinding dry ice cubes are formed between the pressing strip and the grinding wheel, so that the grinding efficiency of the dry ice cubes can be effectively improved, the pressing strip is in a static state, the grinding wheel is in a dynamic state to continuously extrude the dry ice cubes towards the direction ofthe pressing strip to rea
