Paint spraying machine and paint spraying method thereof

Abstract

The invention relates to a paint spraying machine and a paint spraying method thereof, and belongs to the field of cast pipe paint spraying. The paint spraying machine comprises a front conveying rail, a conveying chain, a rear conveying rail, a rack, a paint spraying trolley, a drying room and a heating station, wherein the front conveying rail is arranged at the front side of the conveying chain; the rear conveying rail is arranged at the rear end of the conveying chain; the paint spraying trolley is movably arranged on the rack; the heating station comprises a driven riding wheel, a drivingriding wheel, a heating driven riding wheel, a heating driving riding wheel and a heating room; the heating room and the drying room are arranged on the ground; a heat source of the heating room is transmitted to the drying room; the conveying chain is arranged between the driven riding wheel and the driving riding wheel; and the heating driven riding wheel and the heating driving riding wheel are arranged on the two sides of the conveying chain. The paint spraying machine is simple and reasonable in structural design, safe, reliable, convenient to assemble and disassemble, capable of reducing labor intensity and improving paint spraying efficiency, high in positioning accuracy, good in paint spraying quality, and capable of saving space and enabling a cast pipe to rotate at a constant speed.

Description

technical field [0001] The invention relates to a structure and a method, in particular to a safe and reliable painting machine and a painting method thereof, belonging to the field of painting of cast pipes. Background technique [0002] The cast pipe industry is a traditional manufacturing industry. Over the years, the cast pipe factories have been using simple single-station external painting equipment with old structures. The cast iron pipes painted by the equipment have uneven paint thickness, poor paint quality, high labor intensity for workers, and pollution. The working environment does not guarantee the safety and health of the operators, the degree of automation is low, and the production efficiency is low. [0003] As the market demand for cast pipes continues to increase, the strength index, corrosion resistance, and smoothness of the surface treatment of cast pipes continue to improve. Ordinary manual painting and single-station painting equipment are increasing...

AI Technical Summary

Problems solved by technology

Although the trolley is easy to use, requires less space, and can easily turn the surface of the workpiece to be sprayed to the worker during spraying, the paint thickness is uneven, the paint quality is poor, and the casting pipe cannot be positioned, so it still has the above defects.
