Surface atomization plastic repairing spray head and plastic spraying device for damaged wave-shaped fence guard plate

The invention discloses a surface atomization plastic repair spray head for a damaged waveform fence guard plate and a plastic spraying device, and relates to the technical field of plastic spraying. Comprising an atomization spray head frame, atomization spray holes are formed in the atomization spray head frame, an atomization plastic spraying head is rotationally connected to the inner wall of the atomization spray head frame, a plastic spraying assembly is installed in the atomization spray head frame, and the plastic spraying assembly comprises a first through pipe. Through the arrangement of the plastic spraying assembly and the circulating air assembly, when the spraying head sprays atomized materials, the plastic spraying assembly can clean the atomization plastic spraying head, the materials are prevented from being blocked in the atomization plastic spraying head, meanwhile, in the pause state, the air supply device can move the materials in the atomization plastic spraying head into the conveying p
