Anti-powder-caking dehumidifying glaze material distribution drying device and drying method and control method of anti-powder-caking dehumidifying glaze material distribution drying process

Abstract

The invention relates to an anti-powder-caking dehumidifying glaze material distribution drying device and drying method and a control method of an anti-powder-caking dehumidifying glaze material distribution drying process. The anti-powder-caking dehumidifying glaze material distribution drying device is composed of a feeding module, a material distribution module and a material suction module which are sequentially connected and operated, and the lower part of a material distribution belt of the material distribution module is provided with heating equipment for heating, drying and dehumidifying the material distribution belt and a green brick. The control method comprises the following steps that (1) an induction electric eye senses the green brick, and the glaze material distribution system outputs a signal to the material distribution module; (2) the system detects whether the glaze material is lacking or not, and if the glaze is lacking, the feeding module outputs dry particles,glaze powder or frit and other glaze to the material distribution module; (3) if the glaze is not lacking, the material distribution module distributes and feeds the material to the belt; (4) heatingequipment controls the temperature to heat and dry and dehumidify the material distribution belt and the green brick by a temperature controller, so that the dry particles are uniformly distributed onthe surface of the green brick; (5) the surface of the green brick is decorated; (6) a dry particle material suction nozzle of the material suction module will suck away the dry particles that are not fixed by a glue; (7) the recycled residual material is recycled to the step (3) through a recovery device; and (8) when no residual material is recycled, the green brick is fired.

Description

technical field [0001] The invention relates to the technical field of ceramic inkjet printing, in particular to a drying device for preventing powder agglomeration and dehumidifying glazed cloth, a drying method and a control method. Background technique [0002] With the popularization and application of ceramic inkjet printing technology in the production of ceramic tiles, the surface effect of ceramic tiles is highly homogenized. Manufacturers use dry granule, glaze powder or frit technology to decorate the glazed surface of ceramic tiles, print documents by designing glue that matches the decorative pattern, use an inkjet printer to spray glue on the place where the cloth is needed, and then use the dry granule The machine spreads dry granules, glaze powder, frit and other glaze materials on the brick surface sprayed with glue patterns, and then uses the ventilation equipment to suck away the dry granules, glaze powder or frit that are not bonded to the glue to form the...

Problems solved by technology

However, there are certain deficiencies in the application of this process: First, in the process of production, because the brick adobe of the production line has a certain temperature, as the hot air of the adobe dissipates, the water molecules in the air will be on the dry grain cloth belt. Condensed into water mist, when the dry grains and other glazes fall on the fabric belt, they are easy to agglomerate when they touch the water mist, which makes the uneven distribution of the dry grains and causes surface defects of the bricks, which affects the overall decorative effect of the dry grains; the second is that the bricks are conveyed During the process, the temperature of the billet gradually decreases as the heat evaporates, which is not conducive to the rapid drying of the protective glaze applied on the brick billet in the subsequent process, and affects the normal production of the product
