The rotary cleaning and
drying device comprises a box body with the hollow bottom, passing openings are formed in the lower portions of the left side wall and the right side wall of the box body, the ends of
piston rods of first air cylinders are fixedly installed on safety
doors located below the first air cylinders in a one-to-one correspondence mode, and a fixing frame is fixedly installed in the middle of a top plate of the box body. A second air cylinder which is arranged in the reverse direction is fixedly installed on the
fixed frame, a
powder barrel positioning plate is fixedly installed at the bottom end of a rotating rod, a spray head installation frame is fixedly installed at the end of a
piston rod of a third air cylinder, and a high-pressure rotating spray head is installed on the spray head installation frame. According to the rotary cleaning and
drying device for the
powder barrel, the complexity of manual operation and potential safety hazards possibly caused by manual operation are reduced, cleaning and
drying are combined into one device, the uniformity of cleaning and drying is ensured, the cleaning and drying effects are remarkably improved, the cleaning efficiency of the
powder barrel is improved, the labor intensity of workers is reduced, and the production cost is reduced. And meanwhile, the cost is greatly reduced.
