AI Technical Summary
Traditional flexible printing rollers are prone to ink residue and paper debris clogging the ink pores during high-speed printing, resulting in color differences and missing dots. Furthermore, existing cleaning methods cannot thoroughly clean the ink pores, which may damage the roller surface and cause environmental pollution.
The grooved wheel mechanism and the dial are used to achieve precise rotation of the anilox roller. The lifting and lowering of the cleaning mechanism is controlled by the connecting rod and slider mechanism. The brush and the discharge pipe are used for synchronous rotating brushing. The stirring rod in the storage tank prevents the cleaning liquid from settling and achieves centralized recycling of the cleaning liquid.
It achieves precise alignment and cleaning of ink pores, avoids the waste of high-viscosity cleaning fluid, ensures clean production, and reduces environmental pollution.
