Equipment for decorating waffle surface of ceramic brick, and decoration method of using the equipment

Abstract

The invention discloses a device for decorating concave-convex surfaces of ceramic tiles, which includes a conveying line, and is characterized in that at least a group of inkjet printers for color separation and overprinting of ceramic color glazes, dusting powder machines and vacuum cleaners. The decoration method is as follows: on the concave-convex surface of the ceramic tile or the printing material, spray glue with an inkjet printer, sprinkle the colored glaze with a powder spreader, and blow and suck the unadhered colored glaze with a vacuum cleaner. The invention utilizes the digital imaging technology of the printer to transfer the ceramic color material to the concave-convex surface of the ceramic tile indirectly and in stages, without plate making, quick production change, overcoming the difficulty of making ink-jet printing ink with ceramic color material, and having high economic benefits , good effect and other advantages.

Description

technical field [0001] The invention relates to a decoration device and method for the surface of ceramic tiles, in particular to a fine decoration device for the uneven surface of ceramic tiles and a decoration method using the device. Background technique [0002] The surface of ceramic tiles can be divided into flat type and concave-convex type according to the flatness. Screen printing and roller printing are commonly used methods for surface decoration of ceramic tiles. For flat ceramic tiles, screen printing and roller printing can achieve a good continuous texture effect, but for uneven wood and imitation natural stone Type surface ceramic tiles, screen printing and roller printing are difficult to achieve a good continuous texture performance, and there are defects such as missing flowers and broken lines. Ceramic tiles with concave and convex surfaces can also be decorated with roll-screen dry powder printing equipment, but the accuracy of the performance is poor, ...

AI Technical Summary

Problems solved by technology

There are very few inorganic pigments that can emit close to primary colors (such as red and yellow) under high temperature conditions. Most of the ideal ones are zircon series pigments, and other series of pigments are easy to change color at high temperatures; second, the accuracy of inkjet printing It mainly depends on the fineness of the printing ink, that is, the fineness of the coloring material. It is usually less than 1u, and the fineness is required to be less than 0.2u. However, the zircon series coloring materials are hard and difficult to grind. The color effect is not good, and the average particle size of commonly used ceramic pigments is greater than 5u; third, the hardness of inorganic pigments is high, and the wear on the nozzle is also large; and the specificity is large, the printing ink is easy to precipitate

Therefore, it is difficult to manufacture inkjet printing inks with ceramic pigments
