[0002] Ceramic tiles are a material used in construction and decoration, usually made of ceramic materials. They have the characteristics of high hardness, wear resistance, and easy cleaning. In order to increase the bonding strength between tiles and adhesives, increase the contact area between tiles and cement mortar, and improve the firmness of paving, the back of the tiles is usually given a specific texture treatment.
[0003] The prior art discloses a device and a method for making anti-falling ceramic tile back patterns, which include using a hydraulic system to separate a back pattern forming piece of a ceramic tile body back pressure platform from a back pressure platform plate. When the ceramic tile body is pressed and formed, the hydraulic system applies pressure to make the back pattern forming piece protrude, thereby engraving the back pattern of the ceramic tile body; when demolding, the hydraulic system retracts pressure to make the back pattern forming piece retract and be flush with the back pressure platform plate, and then the back pressure platform plate is separated from the ceramic tile body for demolding; when the back pattern forming piece of the ceramic tile body back pressure platform protrudes under hydraulic pressure, it forms an acute angle with the back pressure platform plate that is equal in angle but in different directions, and the formed ceramic tile back pattern cross-section appears as a parallelogram, and in the entire ceramic tile, it appears as an oblique column lattice or oblique groove body pattern with different directions.
[0004] With regard to the above-mentioned related technologies, after the ceramic powder is pressed into a ceramic tile blank through a pressing mold, the back-grain forming part is driven by a hydraulic system to apply force to the ceramic tile blank, so that the bottom wall of the ceramic tile blank is concave to form a back grain. However, during the rolling process, the ceramic powder on the ceramic tile blank is affected by the pressure and transfers irregularly around the back grain, resulting in the change of the position of the ceramic powder around the back grain. After high-temperature firing, quality problems such as pores or protrusions will appear in the area around the back grain, affecting the product quality of the ceramic tile. Summary of the invention
