[0002] Surface treatment is a crucial step in screw production. Sandblasting, a commonly used surface treatment method, can effectively remove impurities and oxides from the screw surface, increase surface roughness, and improve the adhesion of subsequent coatings.

[0003] Utility model patent application number 202022701439.0 discloses a sandblasting device for surface treatment in screw production, including a chassis, a working chamber, a sandblasting head, and a blower. A waste sand hopper is connected to the bottom of the chassis, and four support legs are connected to the bottom of the chassis. The waste sand hopper is located inside the four support legs. A blower base is connected to one side of the support legs on the front side of the chassis, and a blower is connected to the top of the blower base. The blower is connected to a sand discharge pipe. One end of the sand discharge pipe is connected to the waste sand hopper, and the other end of the sand discharge pipe is connected to a collection box located below the waste sand hopper.
