Anticorrosive paint coating device

The invention discloses an anticorrosive paint coating device, and relates to the technical field of coating devices. The paint supply device comprises a paint supply groove, a supporting shaft penetrating through the paint supply groove is fixed to the top of the paint supply groove, an elastic adjusting piece is rotationally connected to the position, located in the paint supply groove, of the supporting shaft, supporting frames are fixed to the two ends of the elastic adjusting piece through bolts, and the supporting frames are rotationally connected with the supporting shaft; and a plurality of coating structures are rotationally connected between the two supporting frames. When the anti-corrosion coating device encounters an object with the anti-corrosion coating coating faces not located on the same plane, the adjusting rods in the coating structure are adjusted, the two adjusting rods rotate relatively, the two adjusting rods are folded outwards or inwards, the coating structure attached to the object
