Anti-powder agglomeration dehumidification glazed cloth drying device, drying method and control method

Abstract

The invention relates to a drying device for preventing powder agglomeration and dehumidification glazed cloth, a drying method and a control method. Anti-powder agglomeration and dehumidification glazed fabric drying device is composed of a feeding module, a fabric module and a suction module connected in sequence. The fabric belt of the fabric module is equipped with a heating device for heating, drying and dehumidifying the fabric belt and bricks. equipment. Control method: ⑴The induction electric eye senses the brick, and the glaze distribution system outputs a signal to the distribution module; ⑵The system detects whether there is a lack of glaze, and if yes, the feeding module outputs glazes such as dry particles, glaze powder or frit to the distribution module; ⑶ No, the material distribution module feeds the material to the belt; (4) the heating equipment controls the temperature by the temperature controller to heat, dry and dehumidify the material belt and the bricks, so that the dry particles are evenly distributed on the surface of the bricks; (5) the surface of the bricks is decorated; (6) the drying of the suction module The grain suction nozzle sucks away the dry grains that are not fixed by glue; (7) the recovered residual material is recycled to step (3) through the recycling device; (8) when there is no residual material recovered, the 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
