Description

Technical Field

[0001] The present invention relates to the technical field of tile production, in particular to an inkjet printing production process and a production system for imitation-textured travertine tiles. Background Art

[0002] Natural stone travertine refers to a unique stone material that is formed on the surface and inside of the stone after thousands of years of water immersion or exposure to a relatively humid environment in the lava cave area. Water vapor penetrates into the stone and causes long-term erosion. Natural travertine has a natural and simple decorative effect and has always been a high-end building decoration material. However, due to limited material resources, high costs and high prices, its large-scale use is restricted. People have always hoped to develop artificial stones with shapes and decorative effects close to natural stones and low costs to replace natural travertine. Ceramic tiles are the best products to imitate natural travertine, but due to the difficulty of process technology, they have not yet been mass-produced.

[0003] In recent years, with the introduction of inkjet printing technology, a new trend has emerged in the market for inkjet-infiltrated tiles. These tiles are characterized by applying a base glaze or using secondary fabric to form the tiles, followed by a drying step and then spraying with penetrating ink. Because the ink has a certain penetrating property, the pattern penetrates the base glaze or the tiles, allowing for direct polishing after firing.

[0048] Kaolin, feldspar and quartz ceramic raw materials are put into the storage unit 1 and mixed evenly. Then, the mixed raw materials are conveyed to the ball mill 2 through the screw feeder 4. The raw materials are ground into a uniform fine slurry. A composite iron remover combining permanent magnet and electromagnetic is used to absorb iron impurities in the raw materials.

[0049] The raw material slurry is put into the spray drying tower 3, and the composite atomization technology combining ultrasonic and pressure is used to atomize the slurry and form particles of the desired particle size. The granular raw materials are then placed into a mold and pressed into a green body by a press 5;

[0050] The waste heat from the drying kiln 6 is used to dry the green body, reducing energy consumption. Then, a multi-zone temperature precision control system is used to achieve precise temperature control of the green body at different stages and to fire the green body.

[0051] The fired green body is cut, polished and heated by the semi-finished product processing equipment 7, and the green body is dried at multiple temperature groups. According to experimental tests, the temperature can be controlled at 150°C, 180°C, 200°C or 250°C.

The motor 7204 drives the cutting disc 7205 to rotate. At the same time, the linear motor 1 7202 controls the lateral movement of the cutting disc 7205 to cut the blank. The cut blank is then transported to the grinding unit 730. The cylinder 2 7304 pushes the adjustment table 7305 close to the blank. The driving member adjusts the angle and position of the supporting table 7313 so that the blank is stably clamped. The fan 7315 transports air through the pipe 7316 to the passage inside the supporting seat 7311 and the ball head 1 7312. After being heated by the heating plate 7317, the air is ejected from the air jet hole 7314 to heat the blank. The linear motor 2 73 28 adjusts the position of the installation box 7329, and the actuator 7331 drives the driving column 7330 to rotate, driving the grinding belts 7333 of different specifications to grind the edges of the blank. After the blank is cut and polished, in this embodiment, the heating plate 7317 continues to work to maintain the temperature of the blank at 180°C to dry the blank. The dried blank is transported to the inkjet printer 8 through the conveyor 10, and inkjet printing is performed according to the designed imitation travertine pattern. The printed tiles are transported to the inorganic silicon coating equipment 9, and the inorganic silicon coating equipment 9 performs hybridization treatment according to the surface condition of the tiles. Finally, the hybridized tiles are inspected by the detection equipment, and qualified products are screened out for packaging and storage.

A production process of an inkjet printing production system for imitation travertine tiles based on any one of claims 1 to 4, characterized in that: The specific steps include: Put kaolin, feldspar and quartz ceramic raw materials into the storage unit and mix them evenly. Then, the mixed raw materials are conveyed to the ball mill through a screw feeder to grind the raw materials into a uniform fine slurry. A composite iron remover combining permanent magnet and electromagnetic is used to absorb the iron impurities in the raw materials. The raw material slurry is put into the spray drying tower, and the composite atomization technology combining ultrasonic and pressure is used to atomize the slurry and form particles of the desired particle size. The granular raw materials are then placed into a mold and pressed into a green body through a press. The waste heat from the drying kiln is used to dry the green body, reducing energy consumption. Then, a multi-zone temperature precision control system is used to precisely control the temperature of the green body at different stages and fire the green body. The fired green body is cut, polished and heated by semi-finished product processing equipment, and dried at a temperature of 150-250℃. Then, the heated and dried green body is inkjet printed by an inkjet printer, and the residual heat of the green body is used to absorb the ink to form tiles. Inorganic silicone coating equipment is used to perform surface hybrid treatment on tiles to achieve anti-fouling effect.
