Plastic spraying equipment suitable for surface of steel pipe

The utility model belongs to the technical field of plastic spraying, and particularly relates to steel pipe surface plastic spraying equipment which comprises a fixing table, an operating table and a fixing frame. An operation table is arranged at the top of the fixed table; a fixing frame is fixedly connected to the top of the operation table; at the moment, the spraying gun sprays plastic on the steel pipe, the steel pipe can be comprehensively sprayed through rotation of a motor, the steel pipe enters a second conveying roller after just coming out of a spraying box and is conveyed to the next link to be machined, and in the step, through the arranged spraying box, the plastic spraying range of the spraying gun is effectively reduced, and waste of plastic spraying materials is reduced; and meanwhile, the range of diffusion of the plastic spraying material in air is reduced, pollution to a workbench and other equipment is reduced, pollution to air is reduced, the safety of workers during working is effecti
