Marine outfitting product surface spraying device

The invention relates to the related technical field of ship outfitting piece machining, in particular to a marine outfitting product surface spraying device which comprises an annular rail, a rail trolley, a rod material positioning mechanism, a feeding mechanical arm, a spraying nozzle, a hot air drying nozzle and a material returning mechanical arm. A group of annular rails are symmetrically arranged; according to the surface spraying device for the marine outfitting product, the surface spraying device for the marine outfitting product is formed by combining the annular track, the track trolley, the rod positioning mechanism, the feeding manipulator, the spraying nozzle, the hot air drying nozzle and the material returning manipulator, so that a to-be-machined rod can rotate automatically in the conveying process; according to the spraying device, all the surfaces of the to-be-machined rod material can be evenly sprayed with the anti-corrosion layer, the spraying effect of the anti-corrosion layer is impr
