Description

Technical Field

[0001] The present application relates to the technical field of ceramic production, and more specifically, to a glazing process and device for ceramic tiles with a three-dimensional grid-textured glaze surface. Background Art

[0002] With the rapid development of China's ceramic production technology and technology, personalized products have become prominent in the ceramic tile market, and product development has begun to move towards high-end. While targeting the high-end market, Chinese ceramic tile companies have emphasized adjusting product structure and increasing product added value, while also taking into account the overall interests of the industry, and have achieved sustainable development through efforts to improve product technology content, increase independent innovation, and cultivate independent brands.

[0003] Among various ceramic tile products used for indoor and outdoor space decoration, people are increasingly pursuing products with non-bright light stimulation. Antique tiles are mainly soft and matte, without light pollution. Due to their dense surface, excellent anti-fouling performance, and easy cleaning and maintenance, they have replaced a large number of natural stone, wood, wallpaper and wall cloth and other materials, and gradually become the best choice for wall and floor decoration materials.

[0004] From a technical point of view, antique tiles evolved from glazed tiles and are essentially glazed porcelain tiles. Glazed antique tiles are mainly divided into matte glaze, dry granular glaze, and replica glaze. They use inkjet printing technology and integrate advanced technologies such as digital molds, semi-polishing, soft polishing, and fine carving. They cover the characteristics of various textures such as imitation stone, imitation wood, imitation cloth, imitation leather, and imitation metal, and have attracted the attention of the new generation of consumers born in the 1980s or early 1990s who like novelty. Among ceramic tiles with imitation cloth texture features, the grid-like cloth pattern element style is the focus and pursuit of major ceramic tile design and R&D masters, and has become an indispensable design direction for each Bologna Ceramic Exhibition in Italy.

[0005] The vast majority of imitation plaid fabric products currently on the market have the following methods to express the texture and pattern of the fabric:

[0006] 1. Through the use of a cloth-like mold with a specific lattice feature pattern, the surface of the glaze blank presents a lattice feature pattern after the cloth is stamped and glazed, and a lattice texture is formed after firing. This method requires a specially designed ceramic stamping mold.

[0007] 2. Through the inkjet file design of ever-changing plaid texture decoration, the conventional inkjet printer can directly print out plaid-style patterns of different colors to directly express the effect of imitating cloth texture. This is the simplest and most common process technology method. It has the pattern characteristics of plaid patterns and can be directly decorated on flat or concave and convex mold surfaces.

[0008] 3. Print directly out checkered patterns of different colors through a conventional inkjet printer, then screen and design inkjet files with different checkered texture decorations, and print functional digital carving ink on them. After firing, the mold with digital checkered texture and imitation cloth texture effect are presented.

[0009] 4. By screening and designing inkjet files with different lattice textures, ordinary multi-color ceramic inks with inkjet printing cloth patterns are used, and then functional digital glue inks with local effects are superimposed. Finally, a certain amount of dry granular glaze is applied through dry granular fabric equipment to express it. After firing, ceramic tiles with three-dimensional concave and convex cloth texture and visual effects are formed in combination with the cloth pattern.

[0010] Through the above methods, imitation cloth-patterned ceramic tiles with lattice textures can be produced with different decorative styles, different textures and visual effects.

[0011] However, in the past decade, due to the rapid promotion of inkjet printing, the industry has become increasingly homogenized. The above methods of preparing imitation cloth-textured ceramic tiles with lattice textures have low imitation costs. Once the carefully designed products of enterprises are on the market, they are likely to attract a large number of successors to follow suit. In order to raise the imitation threshold of ceramic products and make product quality and connotation more brand-expressive, tile development companies also need to work hard to integrate global resources from the manufacturing and production end to create advantageous areas with unique brand manufacturing and cultural value imprints.

[0012] In the ceramic production process, glazing technology refers to the process of applying glaze slurry on the surface of the formed ceramic body. Glazing methods include throwing glaze, spraying glaze, pouring glaze, etc. At present, the glazing devices commonly used in large-sized ceramic tiles in the architectural ceramics industry are mostly flat-slit pouring glaze, bell-shaped pouring glaze, high-pressure spraying glaze series and other devices.

[0013] The so-called flat-slit glazing method (also known as duckbill glazing method) is that the glaze slurry flows out from the flat gap of the glazing device to form a glaze curtain. This equipment is particularly suitable for glazing secondary fired bricks with uniform glazing and relatively small glaze slurry density (1.40-1.55).

[0014] The main working principle of the bell-type glaze pouring device is that the glaze slurry with a certain potential energy difference flows on the round bell to form a semi-circular glaze curtain of equal thickness. When the body passes through, a layer of glaze is poured on it. Using this method of glazing, the desired thickness of the glaze layer can be obtained by adjusting the thickness of the glaze curtain, the concentration of the glaze slurry and the speed of the conveyor belt. It can be used in occasions where the glaze slurry has a relatively large specific gravity (1.70-1.85).

[0015] The high-pressure glaze spraying equipment uses the set high pressure to evenly atomize the glaze slurry through the nozzle group and spray it evenly on the surface of the brick.

[0016] However, the above traditional equipment alone cannot achieve a glazing effect with specific regular three-dimensional shape pattern characteristics during the glazing process.

[0017] Therefore, the prior art needs to be improved. Summary of the invention

[0060] In order to achieve a glazing effect with specific regular three-dimensional shape pattern characteristics during the glazing process, the present invention provides a glazing process for ceramic tiles with a three-dimensional grid texture glaze surface, wherein a linear multi-porous glazing machine is used to spray glaze on the green body, wherein the linear multi-porous glazing machine has a row of round hole nozzles arranged in a straight line, and the glaze slurry forms a cylindrical fine line flow through the row of round hole nozzles arranged in a straight line, which is sprayed onto the surface of the green body to form flat elliptical glaze strands, which are wetting and diffused and fused with each other, gradually forming a glazing effect with a three-dimensional grid pattern on the surface of the green body.

[0061] Various non-limiting embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0062] See also Figure 1 , Figure 1 The glazing process of the ceramic tile with a three-dimensional grid texture glaze surface in this embodiment is shown in FIG. , which includes the following steps:

[0063] S100, pre-providing a linear multi-hole glazing machine, so that the linear multi-hole glazing machine is provided with a row of round hole nozzles arranged in a straight line.

[0064] In this embodiment, in order to realize the glazing process of ceramic tiles with a three-dimensional grid texture glaze surface, this embodiment adopts a linear multi-hole glazing machine provided in advance, so that the linear multi-hole glazing machine is provided with a row of round hole nozzles arranged in a straight line ( Figure 2 ). For example, the linear multi-hole glazing machine may include: a glaze supply pump and a glaze spray head 100, wherein the glaze spray head 100 may be provided with a row of round hole nozzles arranged in a straight line, and the glaze supply pump is used to provide glaze slurry to the glaze spray head 100, so that the glaze slurry is discharged through the row of round hole nozzles arranged in a straight line under the pressure of the glaze supply pump and the gravity of the glaze slurry itself to form strands of vertical cylindrical thin line flows 441 with a certain diameter range ( Figure 3 ).

[0065] S200, pressing the powder into a shape, and drying it in a drying kiln to form a green body 600.

[0066] In this embodiment, in order to realize the glazing process of ceramic tiles with three-dimensional lattice texture glaze, this embodiment adopts the method of pressing powder into shape and drying it in a drying kiln to form a blank 600. For example, the spray-dried and aged powder can be put into an automatic stamping machine to form a blank 600, and then the blank 600 can be put into a drying kiln for drying. After drying, it can be transported to a linear multi-porous glazing machine by a belt 500 to wait for glazing.

[0067] S300, using a linear multi-hole glazing machine to glaze the blank 600, so that a row of round hole nozzles arranged in a straight line glazes onto the blank 600 and forms a three-dimensional grid glazing layer on the blank 600.

[0068] In this embodiment, in order to realize the glazing process of ceramic tiles with a three-dimensional grid-textured glaze surface, this embodiment uses a linear multi-porous glazing machine to glaze the blank 600, so that a row of round hole nozzles arranged in a straight line glaze the blank 600 and form a three-dimensional grid-textured glazing layer on the blank 600. For example, the cross-section of the glaze slurry flowing out of the round hole nozzle is approximately circular. Under the pressure of the glaze supply pump and the gravity of the glaze slurry itself, the linear multi-porous glazing machine can flow out strands of vertical cylindrical thin lines 441 with a certain diameter range through a row of round hole nozzles arranged in a straight line. The blank 600 passes through the cylindrical thin line 441 under the drive of the belt 500. The cylindrical thin line 441 can form flat elliptical glaze strands 442 ( Figure 4 and Figure 5 As shown in the figure, after being moistened and diffused and fused with each other, the glaze strands 442 can cover the surface of the blank 600. Under the action of the linear speed of the belt 500, the cylindrical thin line flow 441 (glaze slurry) continuously covers the front and rear gaps on the surface of the blank 600. Part of the water is absorbed on the surface of the blank 600, and the glaze strands 442 gradually absorb the water to form a semi-dry and smooth glaze surface. In this way, a glazing effect with a three-dimensional checkered visual effect is formed on the blank 600 ( Figure 6 ), until the next blank 600 is recycled.

[0069] Specifically, step S300 may include the following steps:

[0070] S310, adjusting the glazing specific gravity of the glaze slurry, and pouring the glaze slurry into the liquid storage box of the linear multi-porous glazing machine.

[0071] S320, setting the glazing pressure so that the glaze slurry is evenly poured onto the surface of the blank 600 from the round hole nozzle 440 of the linear multi-hole glazing machine.

[0072] In this embodiment, in order to realize the glazing process of ceramic tiles with three-dimensional grid texture glaze, this embodiment adopts the method of adjusting the glazing specific gravity of the glaze slurry and pouring the glaze slurry into the liquid storage box of the linear multi-porous glazing machine; then setting the glazing pressure so that the glaze slurry is evenly poured from the round hole nozzle 440 of the linear multi-porous glazing machine onto the surface of the blank 600. For example, when the electric eye on the belt 500 senses the blank 600, the glaze supply pump starts and pumps the glaze slurry into the glaze main pipe 210, and finally the glaze slurry is evenly poured from the round hole nozzle 440 of the linear multi-porous glazing machine onto the surface of the blank 600.

[0073] To form a glaze surface with a three-dimensional grid texture, after the glaze slurry is poured onto the surface of the blank 600, two adjacent glaze strands 442 (glaze slurry) need to be fused and crossed to a certain extent. For example, the glaze slurry is vertically downward under the action of gravity and glazing pressure, and is sprayed from the round hole nozzle 440 as a smooth and continuous cylindrical thin line. The spacing L between each two adjacent cylindrical thin lines is consistent with the spacing L between two adjacent round hole nozzles 440. Among them, the diameter of the cylindrical thin line is closely related to the diameter of the round hole nozzle 440.

[0074] Specifically, the nozzle diameter of the circular hole nozzle 440 is 250-500 μm, so as to ensure that the glaze slurry sprayed from the circular hole nozzle 440 is in the form of vertical cylindrical thin lines 441 with a certain diameter range, and the cylindrical thin lines 441 are continuous and uniform.

[0075] The spacing L between two adjacent circular hole nozzles 440 is 2-2.5mm, and a spray glaze is used that can stably adjust to achieve a large area, low specific gravity, low flow rate and a wide range of glazing amounts. This ensures that after the glaze slurry is poured onto the surface of the blank 600 and spreads out, the two adjacent cylindrical fine line flows 441 can merge and form a certain boundary, that is, a three-dimensional grid pattern is formed.

[0076] The glaze specific gravity of the glaze slurry is 1.25-1.55. This ensures that the glaze slurry can be spread on the surface of the blank 600 to form a uniform three-dimensional grid. The surface tension of the glaze slurry is 30-65 dyne / cm. The fluidity and suspension of the glaze slurry: the flow rate of Ford-4 cup is less than 15 seconds; there is no soft precipitation after standing for 24 hours. The fineness of the glaze slurry is through a 63μm sieve. The travel speed of the glaze line is 15-45 meters / minute.

[0077] The glazing pressure is 0.3-0.7 bar, which can ensure that the glaze slurry can be spread on the surface of the blank 600, and after wetting and mutual diffusion and fusion, the glaze slurry can cover the left and right surfaces of the blank 600.

[0078] The surface temperature of the blank 600 is 55-85°C.

[0079] Therefore, under the conditions of appropriate glaze slurry glazing specific gravity, surface tension, body temperature, etc., the surface of the body 600 can present a glaze with a three-dimensional checkered texture. The matte antique glaze has moderate viscosity and tension, so it basically retains its visual and three-dimensional touch after firing.

[0080] S400, firing in a kiln, so that the green body 600 is fired to form a ceramic tile with a three-dimensional grid texture glaze.

[0081] In this embodiment, in order to realize the glazing process of ceramic tiles with a three-dimensional grid texture glaze, this embodiment adopts kiln firing, so that the blank 600 is fired to form a ceramic tile with a three-dimensional grid texture glaze. For example, after the blank 600 is glazed by the linear multi-porous glazing machine, the blank 600 can enter the multi-channel inkjet printer for color or functional ink inkjet decoration, and then decide whether to use the dry particle decoration process according to the design process requirements. When dry particle decoration is required, glue ink inkjet decoration is first performed, and then dry particle spreading or recycling is performed, and then drying and glaze line drying are performed. After that, the blank 600 can be sent to the kiln for firing to form a ceramic tile with a three-dimensional grid texture glaze ( Figure 7 ).

[0082] Therefore, this embodiment forms an artistic visual and tactile effect with a unique three-dimensional regularly spaced checkered pattern through a linear multi-porous glazing machine, thereby creating a three-dimensional sense and artistic taste of the checkered matte ceramic antique tiles, enriching the variety of patterns and colors, and better meeting the choice of personalized varieties by consumers, thereby effectively raising the technical threshold for malicious competition and imitation dumping by industry competitors.

[0083] Specifically, before step S200, the following steps are also included:

[0084] The blank 600 is glazed with a bell-shaped glazing device, so that a first layer of bottom glaze 610 is formed on the blank 600 .

[0085] In a certain embodiment, in order to realize the glazing process of ceramic tiles with a three-dimensional checkered textured glaze, this embodiment adopts, before step S200, also includes: using a bell-shaped glazing device to glaze the blank 600, so that a first layer of base glaze 610 is formed on the blank 600, and then using a linear multi-porous glazing machine to glaze the blank 600, so that a row of round hole nozzles arranged in a straight line glaze onto the blank 600 and form a three-dimensional checkered glazing layer on the blank 600, and the three-dimensional checkered glazing layer is located on the above-mentioned first layer of base glaze 610.

[0086] Specifically, after step S200, the following steps are further included:

[0087] The blank 600 is glazed with a bell-shaped glaze sprayer, so that a first glaze layer is formed on the blank 600 .

[0088] In another embodiment, in order to realize the glazing process of ceramic tiles with a three-dimensional checkered textured glaze, this embodiment adopts, after step S200, also including: using a bell-shaped glaze shower to glaze the blank 600, so that a first glaze layer is formed on the blank 600, that is, after the three-dimensional checkered glazing layer is formed, the bell-shaped glaze shower can be used to glaze the blank 600 again, so that a first glaze layer is formed on the three-dimensional checkered glazing layer.

[0089] Specifically, after step S200, the following steps are further included:

[0090] Another linear multi-porous glazing machine is provided, and the green body 600 is glazed by the linear multi-porous glazing machine, so that a second layer of bottom glaze 630 is formed on the green body 600 .

[0091] In another embodiment, in order to realize the glazing process of ceramic tiles with a three-dimensional checkered textured glaze, this embodiment adopts, after step S200, also includes: providing another linear porous glazing machine, using the linear porous glazing machine to glaze the blank 600, so that a second layer of base glaze 630 is formed on the blank 600, that is, after the three-dimensional checkered glazing layer is formed, another linear porous glazing machine can be used to glaze the blank 600, so that a second layer of base glaze 630 is formed on the three-dimensional checkered glazing layer.

One end of the left plate 310 is fixedly connected to the left side of the glaze tube profile 200, and the other end of the left plate 310 is connected to the left side of the supporting bottom plate 320. One end of the right plate 330 is fixedly connected to the right side of the glaze tube profile 200, and the other end of the right plate 330 is connected to the right side of the supporting bottom plate 320.

The glaze inlet main pipe 210 is used to transport glaze liquid to the two nozzle modules 400, and the glaze outlet main pipe 220 is used to recycle the glaze liquid used by multiple nozzle modules 400. The glaze inlet main pipe 210 forms a cycle with the glaze outlet main pipe 220 through the nozzle modules 400. This process helps to maintain the circulation and renewal of the glaze liquid in the system, and can effectively regulate the pressure in the system to avoid damage to the round hole nozzle or a decrease in efficiency due to excessively high or low pressure, and can also reduce the waste of glaze liquid. , can reduce the energy required for the glaze pump to deliver the glaze, reduce energy consumption, improve system efficiency, and increase response speed, so that the glaze can quickly respond to the needs of the nozzle module 400, and improve the dynamic performance of the system. In addition, the glaze main pipe 220 helps to discharge the air in the nozzle module 400, prevent bubbles from accumulating in the glaze and affecting the spraying effect. Through the circulation of the glaze main pipe 210 and the glaze main pipe 220, the concentration of the glaze can be kept stable, the bubble content in the glaze can be reduced, thereby reducing the water content of the glaze slurry and improving the spraying effect of the glaze. It should be understood that the number of nozzle modules 400 is not limited to the above two, and the number of nozzle modules 400 can also be other situations, which are not limited here.

[0097] See also Fig.10 The nozzle module 400 includes a module box body 410, a first liquid inlet pipe 420, a first liquid outlet pipe 430 and a round hole nozzle. The liquid storage chamber 450 of the module box body 410 is connected to the glaze inlet main pipe 210 through the first liquid inlet pipe 420, and the liquid storage chamber 450 is connected to the glaze outlet main pipe 220 through the first liquid outlet pipe 430. For example, the first liquid inlet pipes 420 of the multiple nozzle modules 400 are arranged in parallel with the glaze inlet main pipe 210, and the first liquid outlet pipes 430 of the multiple nozzle modules 400 are arranged in parallel with the glaze outlet main pipe 220, so that the liquid storage chambers 450 of the multiple nozzle modules 400 are connected via the first liquid inlet pipe 420, the first liquid outlet pipe 430, the glaze inlet main pipe 210 and the glaze outlet main pipe 220 to form a glaze liquid circulation, which helps to maintain the circulation and renewal of the glaze liquid in the liquid storage chamber 450, can maintain the stability of the glaze liquid concentration in the liquid storage chamber 450, improve the spraying effect of the round hole nozzle, and ensure the glazing quality of the round hole nozzle.

[0098] In this embodiment, the glaze tube profile 200 is mainly used to provide glaze liquid to the nozzle module 400 and recycle the glaze liquid, and the left side of the glaze tube profile 200 is connected to the left side plate 310 of the nozzle bracket 300, and the right side of the glaze tube profile 200 is connected to the right side plate 330 of the nozzle bracket 300. The nozzle bracket 300 is used to install the nozzle module 400. It can be understood that the glaze tube profile 200 is a part of the nozzle bracket 300. Therefore, the glaze tube profile 200 also has the function of supporting or fixing the nozzle module 400. Its structure is compact, which is conducive to the miniaturized design of the nozzle, and can also provide avoidance space for the nozzle glazing.

[0099] The two adjacent rows of nozzle modules 400 are arranged in an interlaced manner, so that the defect of too large spacing L between the circular hole nozzles 440 at the junction of the two adjacent nozzle modules 400 can be avoided, so that the circular hole nozzles 440 of the two adjacent nozzle modules 400 are seamlessly connected, and the spacing L at the junction is consistent, which can ensure uniform glazing. Among them, the circular hole nozzle 440 can be understood as the existing technology, and the specific structure of the circular hole nozzle 440 is not repeated.
