Problems solved by technology
[0004] In the prior art, the powder coating is usually sprayed on the inner wall of the pipeline by spraying. The phenomenon of uneven distribution of the powder coating on the inner wall of the pipeline is easy to occur in the spraying method. Poor, the spraying effect is poor, which will affect the anti-corrosion performance of the pipeline, and then will affect the service life of the pipeline. The invention provides an internal suction coating device for steel-plastic composite pipe

The invention relates to the field of pipeline machining, in particular to an internal suction coating device for a steel-plastic composite pipe. The internal suction coating device comprises a supporting table and a machined piece, a first base and a second base are arranged on the two sides of the upper end of the supporting table correspondingly, the first base is connected with the supporting table through an adjusting mechanism, the upper end of the first base is fixedly connected with a powder barrel, and powder is arranged in the powder barrel; and a first connecting pipe is fixedly connected to one side of the bottom end of the powder barrel, a hollow barrel is fixedly connected to the upper end of the second base, a second connecting pipe is fixedly connected to one side of the bottom end of the hollow barrel, the machined piece is located between the first connecting pipe and the second connecting pipe, a plurality of mounting discs movably sleeve the outer side of the machined piece and make close contact with the outer wall of the machined piece, and a plurality of second tooth blocks are fixedly connected to the outer sides of the multiple mounting discs correspondingly. The powder is made to move back and forth in the machined piece, the covering effect of the powder on the inner wall of the machined piece is guaranteed, the powder is distributed more evenly, the machining effect is guaranteed, and then the service life and the use performance of the machined piece are guaranteed.
Description
technical field [0001] The invention relates to the field of pipe processing, in particular to an internal suction coating device for steel-plastic composite pipes. Background technique [0002] Steel-plastic composite pipe, the product is based on seamless steel pipe or welded steel pipe, and the inner wall is coated with high adhesion, anti-corrosion, food-grade hygienic polyethylene powder coating or epoxy resin coating. The water supply galvanized plastic-coated composite steel pipe made by pretreatment, preheating, internal coating, leveling and post-treatment process is an upgraded product of the traditional galvanized pipe. The steel-plastic composite pipe is generally connected with threads and grooves. connection, flange connection. There are many classifications of steel-plastic composite pipes, which can be classified according to the structure of the pipe: steel strip reinforced steel-plastic composite pipe, seamless steel pipe reinforced steel-plastic composite...
