Description

Technical Field

[0001] The utility model relates to the technical field of spraying devices, in particular to a surface spraying device for a steel-lined polytetrafluoroethylene pipe with an adjustable spraying range. Background Art

[0002] Steel-lined PTFE pipe is a pipe made of ordinary carbon steel pipe as the base, lined with thermoplastic polytetrafluoroethylene (PTFE) plastic with excellent chemical stability, processed by a specific process, with excellent temperature resistance and corrosion resistance. Steel-lined PTFE pipe often needs to be sprayed with anti-corrosion materials. The spraying device is mainly composed of a spray gun, a spray control system, a material supply system and a motion control system. Its working principle is to use a spray gun to spray paint, paint or other coating materials evenly onto the surface of the workpiece. When processing more pipes, it is necessary to spray multiple places of the pipe at the same time. A single spraying position and spraying place is not convenient for spraying multiple pipes at the same time. The spraying efficiency of the spraying place is low, and it is not convenient to spray different positions of the pipe, which affects the spraying quality. Utility Model Content
