[0002] Sandblasting machines, through the impact and cutting action of abrasives on the workpiece surface, achieve a certain level of cleanliness and varying roughness, thereby improving the mechanical properties of the workpiece surface. This enhances the workpiece's fatigue resistance, increases its adhesion to coatings, extends the durability of the coating film, and facilitates paint leveling and decoration. It also removes surface impurities, discoloration, and oxide layers, while simultaneously roughening the surface of the medium, eliminating residual stress on the workpiece, and increasing the surface hardness of the substrate.
[0003] With the vigorous development of machinery and equipment, the use of sandblasting machines is constantly increasing. However, sandblasting production lines have low intelligence and waste a lot of water resources when rinsing workpieces in the production line.
[0004] Therefore, a wet sandblasting machine is proposed to address the above problems. Utility Model Content

The material tray in the washing room is ultrasonically cleaned by the movable ultrasonic cleaning structure 7. Then, the material tray is moved to the rinsing nozzle 8 by the belt conveyor structure 2 11 for rinsing. After rinsing, the hot air drying structure 10 is activated to send compressed air into the hot air nozzle 9 through the pipeline to blow away most of the water on the surface of the workpiece in the material tray and dry it. After drying, the material tray is conveyed to the automatic unloading structure 12 by the belt conveyor structure 2 11 to complete the wet sandblasting.
