Description

Technical Field

[0001] This utility model relates to the field of glaze spraying technology, specifically to a ceramic glaze spraying device. Background Technology

[0002] Ceramic glaze can be applied to porcelain by spraying. This method is called spray glazing and is a common glazing technique in ceramic production. Spray glazing uses compressed air to atomize the glaze slurry through a spray gun and then sprays it evenly onto the surface of the ceramic body. This method can make the glaze layer more evenly distributed and is especially suitable for ceramic products with complex shapes, such as bodies with openwork or relief designs.

[0003] After spraying, the coated porcelain often needs to be dried to solidify the glaze on its surface before it can be easily handled and processed. This process not only generates some harmful gases that pollute the working environment, but also causes rapid heat loss during exhaust, resulting in resource waste. In addition, without any pretreatment, the adhesion of the glaze to the porcelain surface is limited. Therefore, it is necessary to design a more stable and energy-efficient spraying device. Utility Model Content

[0016] A purification box 4 is fixed at the top of the drying box 3. A diversion hood 5 is installed at the top of the preheating box 2. Diversion pipes 51 are fixed at equal intervals at the bottom of the diversion hood 5. The bottom of the diversion pipes 51 is fixed on the preheating box 2. A heat insulation pipe 6 is fixed between the diversion hood 5 and the purification box 4. An exhaust pipe 43 is fixed at the connection between the heat insulation pipe 6 and the purification box 4. A fan is installed in the exhaust pipe 43. An air inlet pipe 41 is fixed between both ends of the purification box 4 and the drying box 3. An adsorption filter element 42 is fixed inside the purification box 4 and located between the exhaust pipe 43 and the air inlet pipe 41.

[0017] An annular plate 72 is fixed to the upper end of an annular plate 72. A servo motor is fixed inside the annular frame 71.

[0018] Working Principle: First, the entire device is connected to an external power source. Then, using the conveyor belt 11, the porcelain blank is sequentially passed through the preheating box 2, the spraying frame 7, and the drying box 3 to achieve automatic spraying. During this process, the blank's surface is preheated as it passes through the preheating box 2, allowing for better glaze adhesion during spraying. During spraying, the rotation of the annular plate 72 causes the nozzle 76 to rotate around the blank, achieving comprehensive spraying. Furthermore, the distance between the nozzle 76 and the blank can be adjusted using the telescopic sliding of the mounting base 73. This process primarily utilizes the output of the servo motor. The drive gear 77 rotates, and the ring tooth plate 78 drives the ring plate 72 to rotate. The telescopic cylinder 74 drives the mounting base 73 to slide. During drying, the fan in the exhaust pipe 43 continuously draws the gas from the drying chamber 3 into the preheating chamber 2. During this process, harmful substances in the gas are adsorbed by the adsorption filter 42, achieving purification and reducing pollution to the working environment. Furthermore, the combination of the diversion hood 5 and the diversion pipe 51 allows hot air to be evenly injected into the preheating chamber 2, ensuring uniform temperature inside the preheating chamber 2.
