Abstract

The invention discloses a workpiece coating device. The device comprises a base, a supporting frame mechanism is fixed to the base, a pipeline is detachably arranged on the supporting frame mechanism, a first frame body is further fixed to the base, a connecting shaft is rotationally arranged on the first frame body, one end of a rotating connector is coaxially connected with the connecting shaft, the other end of the rotating connector communicates with a liquid conveying pipe, a liquid inlet of the rotating connector communicates with a liquid inlet pipe, so that paint can enter the liquid conveying pipe through the rotating connector, at least part of the liquid conveying pipe penetrates through the pipeline, the liquid conveying pipe and the pipeline are coaxially arranged, the liquid conveying pipe communicates with a plurality of spray heads, a driving motor is movably arranged on the base, and the liquid conveying pipe is detachably connected with an output end of the driving motor through a connector mechanism. The problem that at present, the inner walls of some pipelines with small diameters are difficult to uniformly coat, so that the corrosion resistance of the pipelines is insufficient is solved.

Description

technical field [0001] The invention relates to the field of spray coating of pipe fittings, in particular to a workpiece coating device. Background technique [0002] Transmission pipelines need good coating to ensure the service life of oil and gas transmission pipelines for decades. Due to the environment, the defects of the coating itself and the nature of the steel, the corrosion of the steel pipe is inevitable. The inner and outer coatings of the steel pipe can effectively alleviate the corrosion. At present, for some small diameter pipes, it is difficult to uniform the inner wall of the pipe coating, resulting in insufficient corrosion resistance. Contents of the invention [0003] The object of the present invention is to provide a workpiece coating device, which solves the problem that the inner wall of the pipeline is difficult to coat evenly for some pipelines with small diameters, resulting in insufficient corrosion resistance. [0004] In order to achieve th...
