The printing packaging box uses YAG laser engraving technology to process ceramic mesh rollers. The mesh hole walls are smooth, the mesh walls are neat, the smoothness is high, the ink transfer is precise, and the scraper loss is small. Not only does the ceramic mesh roller have a long service life, but it can also extend the service life of the printing plate. The high-power and high-precision YAG laser engraving machine can engrave 1600lpi mesh rollers. Closed dual scraper cavity ink delivery system for printing packaging boxes. Although the use of two roller, forward scraper, and reverse scraper structures can achieve quantitative ink supply, the ink is often exposed to the atmosphere in large areas, causing the solvent of solvent based ink to evaporate into the surrounding air, resulting in changes in ink characteristics and environmental pollution problems. If water-based ink is used, bubbles will be generated, which will affect the printing quality. The closed double scraper cavity ink delivery system consists of ceramic mesh rollers, two scrapers, sealing strips, ink storage containers, ink pumps, ink hoses, and other components.
In a fully enclosed system, the scraper, seal, gasket, and pressure plate are all mounted on a hollow bracket. They are mechanically (or pneumatically or hydraulically) pushed towards the ceramic mesh roller and subjected to a constant pressure. Then, the ink delivery tube and return tube are connected to the ink pump and ink storage container, respectively, to achieve quantitative ink supply.
The printing packaging box adopts a reverse scraper structure, which is suitable for high-speed operation and reduces the evaporation of solvents and environmental pollution in solvent based inks. The system can also be quickly integrated with an automatic cleaning system to facilitate quick cleaning and reduce ink exchange and downtime.
