[0002] Steel pipe is a steel material with a hollow cross-section, whose length is much larger than its diameter or circumference. In order to improve the anti-corrosion performance of steel pipes during production, a layer of anti-corrosion powder is usually sprayed inside the steel pipe to improve its anti-corrosion performance. At this time, it is necessary to spray the anti-corrosion powder coating on the inside of the steel pipe through an anti-corrosion powder re-coating machine;

In this process, the first spring column and the second spring column respectively realize the shock absorption protection function of the whole device, and the heating lamp is set to realize the heating and storage function of the material inside the storage chamber, and the material is discharged through the spray gun and added to the inside of the spray roller through the feeding port. The micro-rotating motor rotates the spray roller to realize the operation of the spray roller, and the nozzle is conducive to the uniform discharge of the anti-corrosion powder. The sponge strip makes the anti-corrosion powder be evenly applied to the inner wall of the steel pipe. The third telescopic motor realizes the telescopic adjustment of the second telescopic rod, and finally realizes the telescopic adjustment of the spray roller, so that the spray roller can evenly spray on the inner wall of the steel pipe;
