In the process of moving the plate, the impurities on the surface of the plate are scraped off. At the same time, when the rotating shaft two 225 rotates, the plurality of fan blades 226 rotates to generate a large amount of air volume. These air volumes are blown out from the air outlet 214. At the same time, these air volumes blow off the impurities on the surface of the plate, further improving the cleaning effect. After the plate is cleaned, it is cut by the laser cutting device 114. After the plate is cut, a large amount of molten residue is generated during cutting and falls on the surface of the conveying track 213. At this time, the belt pulley four 315 rotates through the rotating shaft two 225 drives the belt two 314 to rotate. The belt two 314 rotates drives the rotating shaft three 312 through the belt pulley three 313. The rotating shaft three 312 rotates drives the roller brush 311 to rotate. The roller brush 311 rotates brushes off the residue on the surface of the conveying track 213, reduces the adhesion of the residue, and avoids that the residue is too much to affect the placement of the plate. The cleaned residue falls into the dust collecting box 113 at the bottom of the roller brush 311 to collect and process.
