Spraying processing device for shell of mixer

The utility model discloses a mixer shell spraying processing device, which relates to the technical field of metal surface treatment and comprises a base, a mounting frame is fixedly mounted at the upper end of the base, a first air cylinder is fixedly mounted on the inner side of the mounting frame, and a spraying head is fixedly mounted at the output end of the first air cylinder. A pipe connector is arranged on the outer side of the upper end of the spraying head. By adopting the structure, after the shaft sleeve parts at the two ends of the barrel shell of the mixer are fixed by the fixing mechanism, the fourth air cylinder is controlled by external control equipment, so that the output end of the fourth air cylinder telescopically pushes the rack to slide on the moving seat, and the rack rotates on the supporting seat through the meshing transmission rotary column; and therefore, the barrel shell of the mixer can be conveniently overturned and sprayed, and the spraying processing efficiency of the barre
