Description

Digital variable color slurry spray printing device spray printing head Technical Field The invention belongs to the technical field of ceramic wall and floor tile production, and particularly relates to a digital glaze spraying, slurry spraying and printing head capable of achieving multiple blend colors. Background The glazing process of the ceramic refers to the step of applying glaze slurry on the surface of a formed ceramic body. The method mainly comprises seven methods of dipping glaze, swinging glaze, glazing, brushing glaze, spraying glaze, and glazing wheel, and adopts corresponding glazing methods according to different shapes and thicknesses of the green body. The glaze spraying method is to spray glaze material onto the surface of the blank by means of glaze sprayer. The glazing method is suitable for all products including large-scale products, products with complex shapes, or products with thin tyres and the like needing glazing for multiple times, can be used for glazing for multiple times, can obtain thicker glaze layers, and is used for glazing in a plurality of ceramic tile factories. The glazing mechanical method combining glazing and spraying can achieve the effects of high efficiency and smooth and flat glaze surface. Technical problem The equipment used for glazing the ceramic wall and floor tiles at present is a bell jar glazing machine and a high-pressure spray gun atomizer, and the glazing effect at present can only obtain a single glaze layer without patterns. The existing inkjet can print the patterned glaze layer, but can only be thin. Moreover, the existing ink jet machine has particularly strict requirements on the performance of materials, is more strict on the fineness of the materials, and cannot realize the spraying of a large number of glaze layers and slurry layers. The production equipment which has wide performance, can be intelligent and is compatible with the water-solvent glaze slurry used in the current production, can rapidly print glaze slurries with various colors in three dimensions, especially can be used for combined spraying of three primary color glaze materials, and particularly is intelligent equipment which can be used for digital spraying and printing of various mixed color glaze spraying slurry. Disclosure of Invention Aiming at the defects of the existing glazing and glaze spraying technology, the spray printing head device can spray monochromatic glaze, can spray instant blending of multi-color glaze slurry, can spray the combination of three primary color glaze, can spray the superposition of various pattern glaze, realizes the development of three-dimensional glaze polishing products, and can realize the development of colorful three-dimensional blank slurry spray polished tiles, thereby replacing the existing heavy and complicated polished tile distribution equipment system. The digital variable color slurry jet printing device jet printing head is simple and convenient to use, has the lowest requirements on consumable materials, particularly has lower requirements on fineness and viscosity of slurry, has extremely low requirements on manufacturing accuracy of nozzle equipment, is easy to realize maintenance, production and use, is extremely suitable for ceramic production workshops with high dust and high humidity and severe environments, has low manufacturing cost, and is unlike the existing piezoelectric ceramic jet printing head which has extremely high manufacturing requirements and extremely strict use environment.
