Description

Ceramic inkjet printer and ceramic inkjet printing method Technical Field

[0001] The present invention relates to the field of ceramic technology, and in particular to a ceramic inkjet printer and a ceramic inkjet printing method. Background Art

[0002] Ceramic inkjet printing is a novel process that combines ceramic surface decoration with computer technology. Using fully automated computer numerical control (CNC) technology to control an inkjet printer, the designed file information is printed directly onto the ceramic surface using multi-color ceramic inks, creating a decorative effect with realistic textures and rich colors. Compared to traditional rubber roller printing, ceramic inkjet printing can automatically generate complex decorative patterns using a computer, eliminating the tedious tasks of making plates, engraving rollers, and mixing glaze slurries. It offers advantages such as simplicity, high efficiency, and high precision.

[0003] For example, the technical solution disclosed in the patent with announcement number CN111036444B, most of the existing ceramic inkjet printing equipment has the problem of complex structure and single function. For example, after the pattern is printed on the ceramic body, it needs to be placed in a high-temperature furnace at 1100℃-1300℃ and calcined for about 30 minutes. However, the colorants used in existing inkjet printer inks are mostly organic pigments. These organic pigments will decompose if directly exposed to high temperatures above 300℃ for a few minutes before they are cured and fixed, resulting in blurred printed patterns. Therefore, it is also necessary to dry or cure the printed pattern of the ceramic body before calcination. However, the ceramic inkjet printing equipment in the prior art is usually not equipped with a drying or curing mechanism, which requires people to configure additional corresponding equipment and devices for processing, which brings great inconvenience to the production of ceramics and increases the burden on enterprises.

[0004] In addition, in the existing technology, when the inkjet printer prints ink directly onto the surface of the ceramic body, the ink will diffuse and spread along the surface pores, causing the edges of the product's printed pattern to become blurred and unclear, especially for products with darker colors and larger ink usage. This is more obvious, which seriously affects the clarity of ceramic inkjet printing and restricts the development and application of ceramic inkjet printing technology. Summary of the Invention

[0015] S3.

Implementation Method

[0035] The specific embodiments of the present invention are described below with reference to the accompanying drawings. In order to fully understand the present invention, many details are described below, but for those skilled in the art, the present invention can be implemented without these details.

[0036] Example 1:

[0037] 1 and 2 , the present embodiment provides a ceramic inkjet printer, comprising a frame 1, a printing device 2 and a driving device 3; the frame 1 is provided with a turntable 11 for placing a ceramic body 10; the printing device 2 comprises a multi-stage nozzle 21, the multi-stage nozzle 21 comprising a first nozzle 211, a second nozzle 212 and a third nozzle 213 coaxially arranged from the inside to the outside; an ink flow channel 214 is provided in the first nozzle 211; a setting liquid flow channel 215 is provided between the first nozzle 211 and the second nozzle 212; a hot air flow channel 216 is provided between the second nozzle 212 and the third nozzle 213; a plurality of multi-stage nozzles 21 are displaced along a set path under the drive of the driving device 3, thereby spraying ink, setting liquid and / or hot air to a specified position of the ceramic body 10. This embodiment optimizes and improves the nozzle structure of the existing ceramic inkjet printer, adopts a nested manner of multiple nozzles to form a multi-stage nozzle with different flow channels, and adopts an ink-setting liquid-hot air arrangement to design each flow channel from the inside to the outside, so that the multi-stage nozzle has the function of spraying different media.

[0038] Referring to Figure 2 , the inner wall port of the first nozzle 211 is a straight tube, allowing ink to be accurately sprayed onto the designated location of the ceramic body 10. The outer wall port of the first nozzle 211 is converging, as are the inner and outer wall ports of the second and third nozzles 212 and 213. This ensures that the sprayed setting liquid and hot air effectively cover the designated area of ​​the printed pattern. Specifically, in this embodiment, the outer contraction angle G of the first nozzle 211 is set smaller than the outer contraction angle H of the second nozzle 212 and the outer contraction angle K of the third nozzle 213.

[0039] Referring to Figures 1 and 2, the printing device 2 also includes a feeding mechanism (not shown), which includes a setting liquid storage tank, a hot air source, and several ink cartridges. Specifically, each multi-stage nozzle 21 is equipped with a feeding box, which includes a mounting cavity for the ink cartridge, a liquid storage cavity connected to the setting liquid storage tank, and a hot air cavity connected to the hot air source. All feeding boxes are connected to the same setting liquid storage tank and the same hot air source. This one-to-many feeding method ensures consistent feeding of the setting liquid and hot air, and facilitates the control and operation of the discharge. Each feeding box is equipped with a separate ink cartridge, so the ink color can be flexibly adjusted according to the requirements of the printing pattern, thereby achieving the printing of different color patterns in one go.

[0040] 1, 3, and 4, the drive device 3 includes an L-shaped mounting plate 31 and a three-dimensional sliding mechanism 32. One side of the L-shaped mounting plate 31 is fixedly connected to the three-dimensional sliding mechanism 32, and the other side is arranged with a plurality of multi-stage nozzles 21. Preferably, the three-dimensional sliding mechanism 32 includes a first screw pair 321, a second screw pair 322, a third screw pair 323, a vertical plate 324, a horizontal plate 325, and a connecting plate 326. The vertical plate 324 is vertically mounted on the surface of the frame 1 and can slide forward and backward via the first screw pair 321. The horizontal plate 325 is vertically mounted on the vertical plate 324 and can slide up and down via the second screw pair 322. The connecting plate 326 is horizontally mounted on the horizontal plate 325 and can slide left and right via the third screw pair 323. The L-shaped mounting plate 31 is fixedly mounted on the connecting plate 326. In addition, each screw pair is equipped with a guide assembly 327 to ensure smooth operation of the three-dimensional sliding mechanism 32. The action of the driving device 3 is specifically controlled by a control box (not shown in the figure). The control box can collect information such as the shape, contour, and humidity of the ceramic body through accessories such as visual sensors, and convert it into control parameters of the driving device 3 based on the design requirements of the staff (printing pattern, process parameters, etc.), thereby controlling the multi-stage nozzle 21 to move along the set path.

[0041] 1 to 4 , the working method of the ceramic inkjet printer provided in this embodiment includes the following steps:

[0042] S1. Place the ceramic body 10 on the turntable 11 of the ceramic inkjet printer, so that the turntable 11 drives the ceramic body 10 to rotate at a uniform speed.

[0043] S2. Adjust the rotational speed of the turntable 11 to V1, activate the second nozzle 212 and the third nozzle 213 of the multi-stage nozzle 21, and simultaneously, drive the multi-stage nozzle 21 along a predetermined path, thereby uniformly spraying the setting liquid onto the designated location of the ceramic body 10 and drying the setting liquid on the surface of the ceramic body 10 with hot air. In this step, the second nozzle 212 and the third nozzle 213 operate at different times. The specific setting principle is: after spraying the set amount of setting liquid, the second nozzle 212 is immediately closed; after ensuring that the setting liquid has dried, the third nozzle 213 is closed.

[0044] S3. Adjust the rotation speed of the turntable 11 to V2, turn on the first nozzle 211 and the third nozzle 213 of the multi-stage nozzle 21, and simultaneously drive the multi-stage nozzle 21 to move along a set path through the driving device 3, thereby uniformly spraying ink onto the surface of the dried setting liquid, and drying the ink on the surface of the setting liquid by hot air, thereby forming a printed pattern. In this step, the working time of the first nozzle 211 and the third nozzle 213 are different. The specific setting principle is: after the ink is sprayed according to the set amount, the first nozzle 211 is immediately closed; after ensuring that the ink is dried, the third nozzle 213 is closed.

[0045] Research has found that the main reason for the diffusion of ceramic inkjet printing patterns is that the pressed ceramic body 10 is relatively dense and has poor ink absorption. Furthermore, the wettability of the interior of the ceramic body 10 is higher than that of the surface. Therefore, the liquid ink cannot be quickly absorbed by the ceramic body 10 during the wetting process, but instead diffuses laterally. Based on this, the present invention proposes the inventive concept of a setting fluid. Prior to inkjet printing, a layer of setting fluid is sprayed on the surface of the ceramic body 10, dried, and then the ink is sprayed onto the dried setting fluid. This allows the ink to be quickly fixed and avoids lateral diffusion. Therefore, the essence of the setting fluid is to inhibit the fluidity of the ink, thereby achieving a rapid setting effect. As a preferred embodiment, the setting fluid comprises 6-9 parts carboxymethyl cellulose, 90-98 parts water, and 0.1-0.9 parts sodium tripolyphosphate. The setting fluid is formed by mixing the carboxymethyl cellulose, water, and sodium tripolyphosphate in a suitable proportion and adding them to a ball mill for stirring and grinding. The preparation method is simple and easy to operate.

[0046] 2 , the flow channels of the multi-stage nozzle 21 are designed to be, from the inside to the outside, an ink flow channel 214, a setting liquid flow channel 215, and a hot air flow channel 216. Therefore, in step S2, by adjusting the rotation speed of the turntable 11 and the displacement path of the multi-stage nozzle 21, it is possible to ensure that the designated printing pattern area is evenly covered with a layer of setting liquid. In step S3, by re-adjusting the appropriate turntable rotation speed and the displacement path of the multi-stage nozzle 21, it is possible to ensure that the ink is accurately sprayed onto the surface of the ceramic body 10 covered with the setting liquid. Since the hot air flow channel 216 is located at the outermost side of the multi-stage nozzle 21, the hot air ejected can effectively wrap the setting liquid or ink inside it, thereby quickly drying the setting liquid or ink while preventing the setting liquid or ink from diffusing outward. Preferably, the drying temperature of the setting liquid is usually controlled at 120-180°C, while the drying temperature of the ink is usually controlled at 140-200°C. Practice has proven that a complete printed pattern can be formed by drying the ink with hot air. Subsequent processes such as spraying glaze or high-temperature calcination will not cause the ink to fade, decompose, or distort, effectively ensuring the clarity of the printed pattern.

[0047] Example 2:

[0048] Referring to Figure 5 , unlike the first embodiment, the printing device 2 of this embodiment further includes infrared lamps 22. Driven by the driving device 2, the plurality of infrared lamps 22 are displaced along a predetermined path, thereby irradiating infrared rays toward a designated location on the ceramic body 10. Specifically, an L-shaped mounting plate 31 is provided below the multi-stage nozzle 21, where the plurality of infrared lamps 22 are arranged.

[0049] 1 to 5 , the working method of the ceramic inkjet printer provided in this embodiment includes the following steps:

[0050] S1. Place the ceramic body 10 on the turntable 11 of the ceramic inkjet printer, so that the turntable 11 drives the ceramic body 10 to rotate at a uniform speed.

[0051] S2. Adjust the rotation speed of the turntable 11 to V1, open the second nozzle 212 of the multi-stage nozzle 21, and simultaneously drive the multi-stage nozzle 21 via the drive device 3 to move along a set path, thereby uniformly spraying the setting liquid onto the designated position of the ceramic body 10. After the setting liquid has been sprayed in the set amount, immediately close the second nozzle 212.

[0052] S3. Adjust the rotation speed of the turntable 11 to V2, open the third nozzle 213 of the multi-stage nozzle 21, and simultaneously drive the multi-stage nozzle 21 along a set path via the driving device 3. This uniformly ejects hot air to dry the setting liquid on the surface of the ceramic body 10. After the setting liquid is dried, close the third nozzle 213.

[0053] S4. Adjust the rotational speed of the turntable 11 to V3, activate the first nozzle 211 and the third nozzle 213 of the multi-stage printhead 21, and simultaneously, use the drive device 3 to move the multi-stage printhead 21 along a predetermined path, thereby evenly spraying ink onto the surface of the dried setting liquid. Hot air is then used to preliminarily dry the ink on the setting liquid surface, thereby forming a printed pattern. In this step, the first nozzle 211 and the third nozzle 213 operate for the same duration. After spraying the predetermined amount of ink, they are immediately closed to facilitate the next step.

[0054] S5. Adjust the rotation speed of the turntable 11 to V4, turn on the infrared lamp, and at the same time drive the infrared lamp 22 to move along the set path through the driving device 3, thereby irradiating infrared rays to the surface of the ceramic body 10 through the infrared lamp 22, thereby solidifying the printed pattern on the surface of the ceramic body 10.

[0055] This embodiment separates the spraying and drying of the setting liquid into two separate steps. Therefore, by adjusting the rotation speed of the turntable 11 and the displacement path of the multi-stage nozzle 21, the setting liquid spraying area and the hot air drying area can be more accurately and simply controlled. Preferably, the hot air drying temperature in step S3 is 120-180°C.

[0056] During the ink jetting process, hot air primarily aids in setting the ink and preliminarily drying it. After the ink is jetted, infrared curing is used to thoroughly dry and solidify the ink. Preferably, the preliminary drying temperature in step S4 is 140-180°C, and the curing temperature in step S5 is 150-200°C.

[0057] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
