Description

Steel plate surface rust-proof coating spraying equipment Technical Field The invention relates to the technical field of metal surface treatment, in particular to steel plate surface antirust coating spraying equipment. Background The rust-proof spraying of steel plate is a key surface treatment process for protecting metal components and prolonging the service life of the metal components in the manufacturing industry. The process forms a continuous and compact protective coating on the surface of the steel plate, so that corrosive media such as moisture, oxygen and the like are effectively isolated, and the process is widely applied to the fields of ships, bridges, storage tanks, engineering machinery and the like. Conventional automated spray equipment often employs a linear pipeline layout of "inlet-spray-cure-flip-secondary spray-secondary cure-exit". The equipment gradually exposes obvious defects in actual production, namely firstly, the production efficiency is bottleneck, the processes of spraying, curing, overturning and the like are required to be carried out in series, the curing time is usually far longer than the spraying time, so that a high-speed spraying unit is required to wait frequently, the whole equipment utilization rate is low, the productivity is limited, secondly, the spraying quality and the cost are not well controlled, the traditional fixed or simple reciprocating spray gun is difficult to intelligently adapt to workpieces with different sizes, the paint is very easy to cause the spraying of the paint to non-workpiece areas, the raw material waste and the environmental pollution are caused, the subsequent cleaning burden is increased, and meanwhile, the uniformity of the coating is also difficult to be accurately ensured. Therefore, the invention provides the steel plate surface antirust coating spraying equipment, which effectively overcomes the defects by constructing a matrix type conveying network taking a steering conveying unit as a core and integrating a double-curing channel and an intelligent spraying system. The equipment utilizes the cooperation of the plurality of steering conveying parts and the linear conveying part to reconstruct a single linear flow into a multi-path system capable of being parallel and circulated, so that the spraying, double-sided curing and overturning procedures can be overlapped in space and time to a high degree, the continuous operation of a core spraying station is ensured, and the productivity bottleneck of a curing link is broken through. Meanwhile, the intelligent fan-shaped spraying unit based on the gas-assisted atomization and mechanical adjustment principle is mounted on the equipment, the width of a spraying fan and the flow of paint can be adjusted accurately in real time according to the width of a steel plate, the thickness uniformity of the coating is ensured, the accurate delivery of the paint is realized, and the waste is obviously reduced. The invention realizes the automatic spraying of the double-sided antirust coating of the steel plate with high efficiency, high quality and low consumption through systematic layout innovation and intelligent control.
