Description

[0002] At present, the ceramic industry mostly adopts the inkjet printing process of inkjet printers to achieve the pattern texture decoration on the surface of ceramic tiles, replacing the early screen printing and gravure printing processes. Among them, ceramic ink is mainly composed of ceramic powder, solvent, dispersant and binder, and contains a lot of oil-soluble and lipid substances. When the color of ceramic tile products is relatively deep, the inkjet volume of ceramic ink increases, and it will repel with the water-based glaze during wet glaze application, resulting in the glaze avoidance defect.

[0051] At present, the ceramic industry mostly adopts the inkjet printing process of inkjet printers to achieve the decorative pattern texture on the surface of ceramic tiles, replacing the early screen printing and gravure printing processes. Among them, ceramic inks are mainly composed of ceramic powders, solvents, dispersants and binders, containing more oil-soluble and lipid substances. When the color of ceramic tile products is relatively dark, the inkjet volume of ceramic inks increases, and it will repel with the water-based glaze during wet glazing, forming an anti-glaze defect. For the problem of anti-glaze defects, usually an additional gravure printing isolation glaze is added after inkjetting. Although this can alleviate the anti-glaze defects caused by wet glazing; however, this not only increases the cost and the complexity of the process, but also cannot completely overcome the anti-glaze defects, especially the solution effect for products with darker colors is even worse. Based on the problem that anti-glaze defects are likely to occur during wet glazing after inkjet printing of ceramic tiles in the prior art, the present invention provides a device for solving the anti-glaze defects of inkjet ceramic tiles. By setting the frame, it can provide protection and support for the combustion mechanism, the combustion-supporting mechanism and the gas delivery mechanism; by setting a conveying component on the frame, it realizes the automatic conveyance of the inkjet ceramic tiles to be glazed (the tile blanks printed with decorative patterns by inkjet printing) through the combustion mechanism, so that the open flame generated by the combustion mechanism bakes the glazed surface after inkjet printing of the ceramic tiles, completely burns the oil-soluble and lipid substances in the ceramic ink, removes the substances in the ceramic ink that can cause anti-glaze defects during wet glazing, and thus solves the anti-glaze defects of inkjet ceramic tiles; for specific details, please refer to the following embodiments.

The air chamber 122 is connected to the combustion assisting mechanism 13 for delivering the air delivered by the combustion assisting mechanism 13 into the combustion tube 123. Then, the gas and air are mixed and burned in the combustion tube 123. At the same time, by providing a plurality of combustion holes 124 on the combustion tube 123, the open fire in the combustion tube 123 can be led out, ensuring the baking effect on the glaze surface after inkjet printing of the ceramic tile, burning the oil-soluble and lipid substances in the ceramic ink completely, and removing the substances in the ceramic ink that can cause the glaze avoidance defect in wet glaze spraying, thereby solving the glaze avoidance defect of the inkjet ceramic tile. Specifically, the aperture of the combustion hole 124 is 4 - 6 mm, the spacing between the combustion holes 124 is 20 - 25 mm, and the number of the combustion holes 124 is determined according to the size of the ceramic tile to be burned.

[0059] It can be understood that by providing the blower 131, the air duct 132, and the plurality of flexible hoses 133, and controlling the one-to-one correspondence between the plurality of flexible hoses 133 and the plurality of combustion components 120, sufficient oxygen is ensured for each group of the combustion components 120, and the treatment effect of the device 10 for solving the glaze avoidance defect of the inkjet ceramic tile on the glaze avoidance defect of the ceramic tile is ensured.

[0060] Please refer to Figure 6, in some other embodiments, the gas delivery mechanism 14 includes: a gas inlet pipe 141 and a plurality of gas branch pipes 142; one ends of the plurality of gas branch pipes 142 are all connected to the gas inlet pipe 141, and the other ends of the gas branch pipes 142 are respectively connected to the torch 121 in one-to-one correspondence; wherein, manual gas valves 143 and gas solenoid valves 144 are provided on each of the plurality of gas branch pipes 142.

[0061] It can be understood that by providing a plurality of gas branch pipes 142, the gas supply to each combustion component 120 can be effectively ensured; at the same time, by providing manual gas valves 143 and gas solenoid valves 144 on the gas branch pipes 142, it provides a guarantee for automatically controlling the gas supply.

It can be understood that by providing the combustion control mechanism 15, the combustion mechanism 12, the combustion-supporting mechanism 13, the gas delivery mechanism 14 and the automatic operation of the conveying component 111 can be automatically controlled, ensuring that the device 10 for solving the glaze avoidance defect of the inkjet ceramic tile starts combustion and drying in time when there is a ceramic tile, and when there is no ceramic tile on the device 10 for solving the glaze avoidance defect of the inkjet ceramic tile, the combustion mechanism 12 is closed in time; ultimately, it can effectively overcome the glaze avoidance defect, avoid energy consumption, and improve the automation level.

Specifically, the combustion controller 151 is arranged on the machine shell 112 and is communicatively connected to the gas solenoid valve 144 and the conveying component 111. By providing the combustion controller 151 and controlling the combustion controller 151 to be respectively connected to the gas solenoid valve 144 and the conveying component 111, the gas delivery mechanism 14 and the conveying component 111 are controlled to operate through the combustion controller 151, and then the combustion mechanism 12 is controlled to operate. Further, the combustion controller 151 is connected to the blower 131 of the combustion-supporting mechanism 13 and controls the operation of the blower 131.

[0064] In some embodiments, the combustion control mechanism 15 further includes: a plurality of photoelectric switches 152, the plurality of photoelectric switches 152 are connected to the combustion controller 151, and the plurality of photoelectric switches 152 are respectively arranged at the conveying component 111 at the front end in the feeding direction of the plurality of combustion components 120.

[0065] It can be understood that by arranging the photoelectric switch 152 at the front end in the feeding direction of the combustion component 120, it is possible to detect and know whether there is a ceramic tile on the conveying component 111, and the ceramic tile first passes through the photoelectric switch 152 and then passes through the combustion component 120; thus, the device 10 for solving the glaze avoidance defect of the inkjet ceramic tile can start the combustion mechanism 12 only when there is a ceramic tile on the conveying component 111; specifically, when the photoelectric switch 152 detects that there is a ceramic tile on the conveying component 111, it sends an electrical signal to the combustion controller 151, and when the combustion controller 151 receives the electrical signal from the photoelectric switch 152, the combustion controller 151 controls the combustion mechanism 12 to start, thereby effectively solving the glaze avoidance defect of the ceramic tile.

[0066] In other embodiments, the combustion control mechanism 15 further includes: an ultraviolet flame detector 153, the ultraviolet flame detector 153 is arranged at the combustion mechanism 12, and the ultraviolet flame detector 153 is connected to the combustion controller 151.

[0067] It can be understood that by arranging the ultraviolet flame detector 153, it is possible to effectively detect whether the combustion mechanism 12 is burning normally, which not only ensures the treatment effect of the glaze avoidance defect but also improves the safety of the device 10 for solving the glaze avoidance defect of the inkjet ceramic tile.

[0068] In other embodiments, the combustion control mechanism 15 further includes: a plurality of electric igniters 154, the plurality of electric igniters 154 are arranged at the plurality of combustion components 120, and the plurality of electric igniters 154 are all connected to the combustion controller 151.

[0069] Please refer back to Figures 1 to 7, in some specific embodiments, a device 10 for solving the glaze avoidance defect of inkjet ceramic tiles is provided. The device 10 for solving the glaze avoidance defect of inkjet ceramic tiles includes: a frame 11, and a combustion mechanism 12, a combustion-supporting mechanism 13, a gas delivery mechanism 14, and a combustion control mechanism 15 provided on the frame 11; the combustion control mechanism 15 is connected to the combustion mechanism 12, the combustion-supporting mechanism 13, the gas delivery mechanism 14, and a conveying component 111; the combustion mechanism 12 is provided with two groups of combustion components 120, the flexible hoses 133 of the combustion-supporting mechanism 13 are provided with two groups, the gas delivery mechanism 14 is provided with two groups of gas branch pipes 142, and the combustion mechanism 12 is provided with two groups of photoelectric switches 152 and two groups of electric igniters 154. The glazed surface of the ceramic tile after inkjet printing is facing up and carried on the transmission roller, and is sequentially transmitted by the conveying component 111 to the first photoelectric switch. After the first photoelectric switch detects the ceramic tile, it sends a first photoelectric signal to the combustion controller 151. After receiving the first photoelectric signal, the combustion controller 151 simultaneously sends electrical signals to the blower 131, the gas solenoid valve 144 on the first gas branch pipe 142, and the first electric igniter 154. The blower 131 and the gas solenoid valve 144 are synchronously opened, and the first electric igniter 154 ignites after a delay of 0.5 seconds to perform glaze avoidance defect treatment on the ceramic tile passing under the first combustion component; then, the ceramic tile after passing through the first combustion component is sequentially transmitted by the conveying component 111 to the second photoelectric switch. After the second photoelectric switch detects the ceramic tile, it sends a second photoelectric signal to the combustion controller 151. After receiving the second photoelectric signal, the combustion controller 151 simultaneously sends electrical signals to the blower 131, the gas solenoid valve 144 on the second gas branch pipe, and the second electric igniter. The gas solenoid valve 144 on the second gas branch pipe is opened, and the second electric igniter ignites after a delay of 0.5 seconds to perform glaze avoidance defect treatment on the ceramic tile passing under the second combustion component; the ceramic tile continues to be conveyed. When the two photoelectric switches 152 do not detect the ceramic tile, they respectively feedback to the combustion controller 151. The combustion controller 151 stops supplying voltage to the gas solenoid valve 144 after a delay of 1.5 seconds, and the gas solenoid valve 144 closes, waiting for the next instruction; during this period, the ultraviolet flame detector 153 is always in an operating state to detect the flame state inside the frame 11. In the normal burning state, if the flame suddenly goes out, the ultraviolet flame detector 153 does not detect the flame signal and feedbacks to the combustion controller 151. The combustion controller 151 immediately issues an instruction to the electric igniter 154 to ignite. If ignition still cannot be achieved, the ultraviolet flame detector 153 feedbacks to the combustion controller 151 again, and the combustion controller 151 stops outputting voltage to the gas solenoid valve 144 to close the gas solenoid valve 144, thereby preventing gas leakage and improving the automation level of the device 10 for solving the glaze avoidance defect of inkjet ceramic tiles.

[0070] In summary, the present invention provides a device for solving the glaze avoidance defect of inkjet ceramic tiles, which includes: a frame, on which a conveying component for conveying ceramic tiles is arranged; a combustion mechanism, which is arranged on the frame and is located above the conveying component; a combustion-supporting mechanism, which is arranged on the frame and is communicated with the combustion mechanism; a gas conveying mechanism, which is arranged on the frame and is communicated with the combustion mechanism. It can be understood that by arranging the frame, protection and support can be provided for the combustion mechanism, the combustion-supporting mechanism and the gas conveying mechanism; by arranging the conveying component on the frame, the inkjet ceramic tiles to be glazed (the tile blanks printed with decorative patterns by inkjet) are automatically conveyed through the combustion mechanism, so that the open flame generated by the combustion mechanism bakes the glaze surface after inkjet printing of the ceramic tiles, completely burns the oil-soluble and lipid substances in the ceramic ink, and removes the substances in the ceramic ink that can cause the glaze avoidance defect in wet glaze application, thereby solving the glaze avoidance defect of inkjet ceramic tiles.
