Description

Technical Field

[0001] This utility model relates to the field of ceramic processing technology, and in particular to a flatbed screen printing machine for 3D glaze line fabric process. Background Technology

[0002] Currently, the mainstream sizes of ceramic tiles produced by enterprises are small to medium-sized: 600×1200mm, 800×1600mm, and 900×1800mm (thickness 6-12mm), suitable for common applications such as walls and countertops. Large-sized slabs: 1200×2400mm and 1600×3200mm (thickness 9-20mm), mostly used for high-end feature walls and furniture veneers. Due to limitations in raw material uniformity, pressing techniques such as roller kilns and continuous presses, and deformation control during firing, domestic enterprises can stably produce small to medium-sized three-dimensional ceramic tile slabs. Large-sized three-dimensional ceramic tile slabs face technological limitations and remain in the experimental stage, unable to meet mass production requirements.

[0003] With consumers' increasing demand for personalized and artistic decoration, the demand for three-dimensional ceramic slabs (3D ceramics) has increased significantly in areas such as feature walls, countertops, and furniture veneers. High-end markets (such as hotels and showrooms) tend to prefer slab products with strong three-dimensionality and unique textures.

[0004] To enhance the three-dimensional effect of 3D ceramics, various methods can be used, including screen printing, laser engraving, and nanoimprinting. However, due to high equipment investment, laser engraving and nanoimprinting technologies are currently mostly used for high-end, small-batch customization and have not yet met mass production requirements. Mainstream companies tend to use screen printing for pattern application, balancing efficiency and three-dimensional effect. This involves using a screen printing machine to apply the glaze. A screen printing machine is a device for printing text and images. It has a frame with a screen inside. During operation, a squeegee scrapes the liquid glaze or fine powder on the screen, causing it to pass through the mesh and be printed onto the substrate.

[0005] However, the above-mentioned screen printing method, when directly applied to the application of large-size 3D ceramic glaze, failed to meet the requirements for pattern formation of large-format ceramic slabs (greater than 1200mm×2400mm). Due to the deformation of the large-size frame on the screen printing machine caused by the large-size application, the printed pattern showed ghosting and distortion, and the repeatability of the applied pattern was low.

[0006] Therefore, there is an urgent need to develop a flatbed screen printing machine that can be used for 3D glaze line fabric technology, especially for processing large-scale ceramic 3D stereoscopic patterns. This machine can effectively avoid ghosting and distortion of patterns, and the pattern application can be highly repeatable. Utility Model Content

[0007] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a flatbed screen printing machine for 3D glazed fabric process.

[0008] The purpose of this utility model is achieved by the following technical solution: a flatbed screen printing machine for 3D glaze line fabric process, comprising a tile conveying mechanism for conveying tiles to be coated with glaze, a glaze application and scraping mechanism for applying and scraping liquid glaze, a large-size screen frame for converting glaze into ceramic surface patterns, and a frame for mounting the glaze application and scraping mechanism and the large-size screen frame; the frame is disposed above the tile conveying mechanism, and the glaze application and scraping mechanism and the large-size screen frame are respectively movably mounted on the frame.

[0009] Furthermore, in the flatbed screen printing machine applied to 3D glazed fabric technology, the large-size screen frame includes four border strips and a screen with a preset pattern. Each border strip is connected end to end to form a square frame, and the screen is fixed inside the square frame. Inclined connecting rods are provided at the four inner corners of the square frame, and each border strip has a hollow cavity inside. The hollow cavity is provided with internal reinforcing ribs that run through the entire hollow cavity.

[0010] Furthermore, in the flatbed screen printing machine applied to 3D glazed fabric technology, the internal reinforcing rib is composed of multiple staggered support pieces, and the cross-section of the internal reinforcing rib is one of X-shaped, cross-shaped, or rice-shaped; the border strip is integrally formed with the internal reinforcing rib.

[0011] The thickness of the frame strip and / or the inclined connecting rod strip is 2-3mm, and the thickness of the internal reinforcing rib is 1-2mm; the width of the frame strip is 80-120mm, and the thickness is 40-50mm.

[0012] Furthermore, in the flatbed screen printing machine applied to the 3D glazed fabric process, the screen uses a tension ≥25N / cm. 2 The high-tensile polyester mesh includes a central hollow area and a surrounding dense area. The entire surface of the mesh is coated with photosensitive emulsion. The central hollow area forms a hollow pattern forming area through exposure. The planar area of ​​the hollow pattern forming area is greater than 1200mm×1200mm.

[0013] Furthermore, in the flatbed screen printing machine applied to 3D glazed fabric process, the flatbed screen printing machine also includes a vacuum device for vacuum negative pressure adsorption to fix the large-size screen frame, and the vacuum device is installed on the frame mounting mechanism.

[0014] Furthermore, in the flatbed screen printing machine applied to the 3D glaze fabric process, the glaze application and scraping mechanism includes a mounting frame, a liquid glaze conveying pipe, and an inclined scraper device. The mounting frame is mounted on the machine frame, the liquid glaze conveying pipe is mounted on the mounting frame and spans across the ceramic conveying direction, and the inclined scraper device is distributed on the horizontal side of the liquid glaze conveying pipe.

[0015] Furthermore, in the flatbed screen printing machine applied to the 3D glaze fabric process, the inclined squeegee device includes a clamping and fixing component and a rubber squeegee disposed within the clamping and fixing component. The rubber squeegee has two pieces, which are distributed in a figure-eight shape on both sides of the liquid glaze conveying pipe.

[0016] Furthermore, in the flatbed screen printing machine applied to the 3D glaze line fabric process, the flatbed screen printing machine also includes a support structure for preventing the middle of the large-size screen frame from sinking. The support structure is arranged on both sides of the conveying direction of the tile conveying mechanism and is located below the middle of both sides of the large-size screen frame.

[0017] Furthermore, in the flatbed screen printing machine applied to the 3D glazed fabric process, the flatbed screen printing machine also includes a frame mounting mechanism for mounting a large-size screen frame and a first displacement adjustment device for finely adjusting the X / Y / Z axis position of the frame mounting mechanism.

[0018] The frame installation mechanism includes semi-frame clamping plates for clamping the two sides of the large-size mesh frame and a top holding member for pressing the large-size mesh frame into the semi-frame clamping plates. The frame installation mechanism is fixedly installed on the first displacement adjustment device. The first displacement adjustment device is selected from one or more combinations of pulley assembly, cylinder, slide rail slider assembly, and gear rack assembly. The large-size mesh frame is installed on the frame through the first displacement adjustment device.

[0019] Furthermore, in the flatbed screen printing machine applied to the 3D glaze fabric process, the flatbed screen printing machine also includes a second displacement adjustment device for adjusting the position of the glaze application and scraping mechanism on the X / Y / Z axes. The second displacement adjustment device is selected from one or more combinations of pulley assembly, cylinder, slide rail slider assembly, and gear rack assembly.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] 1. This application increases the overall size of the screen frame by designing a large-size screen frame, which is suitable for large-scale, large-size 3D glaze line fabric processes. The applied 3D patterns and textures are richer and more three-dimensional, without ghosting or deformation, and the quality is controllable.

[0022] 2. This application improves the structure of the large-size screen frame by designing the screen frame as a hollow structure and setting internal reinforcing ribs that run through the entire hollow cavity in each frame strip, as well as fixing an inclined connecting rod between two adjacent frame strips. This improves the overall rigidity and hardness of the screen frame, effectively preventing pattern deformation, ghosting, and unreproducible phenomena caused by large-area printing of enamel, and improving the durability of the large-size screen frame.

[0023] 3. This application optimizes the design of the internal reinforcing ribs by using a cross-shaped structure, which serves as the most suitable rigid reinforcement structure while meeting the tension requirements for large-span wire mesh installations, thus saving on material costs. The integrated molding process between the frame strip and the internal reinforcing ribs significantly improves the overall strength and rigidity of the large-size wire mesh frame.

[0024] In addition, the inventors optimized parameters such as the thickness and width of the frame strip, internal reinforcing ribs, and inclined connecting rod strips, all based on consideration of the rigidity requirements of large-span fabrics and material consumption costs, to make the optimal parameter selection.

[0025] 4. After the improvement, the wire mesh tension is ≥25N / cm. 2 This ensures that the pattern will not be distorted during printing. At the same time, the screen is divided into open and closed areas, which can meet the needs of pattern application and the installation space requirements of rigid structure reinforcement.

[0026] 5. This application uses a vacuum device to fix the large-size screen frame under vacuum negative pressure, which further prevents slippage during printing and ensures that the pattern will not have defects such as repetition or deformation.

[0027] 6. The glaze application and scraping mechanism of this application combines the functions of glaze application and scraping printing. Two inclined scraper devices are designed on both sides of the liquid glaze delivery pipe, which is horizontally positioned across the surface of the ceramic tile. The glaze is pumped into the liquid glaze delivery pipe through a liquid delivery system and applied through multiple small openings at the bottom of the pipe. While the glaze is being applied, the inclined scraper devices on one side scrape it flat and apply pressure to push it under the screen. Through the pre-set pattern holes of the screen, corresponding patterns can be formed. The design and positioning of the inclined scraper devices and the liquid glaze delivery pipe are suitable for the efficient application of large-format ceramic pigments and glazes.

[0028] In addition, the scraper of the present invention uses a rubber scraper instead of a metal scraper, which to a certain extent protects the polyester wire mesh of the present invention from scratches, improves the service life of the wire mesh, and reduces production costs.

[0029] 7. The large-size screen frame of this application is provided with a support structure at the bottom of the middle section to improve the support force of the middle section of the large-size screen frame and prevent insufficient support in the middle section of the frame, which can easily lead to deformation and deformation of the applied pattern.

[0049] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0050] like Figure 1-9 As shown, a flatbed screen printing machine 100 applied to 3D glaze fabric technology includes a tile conveying mechanism 1 for conveying tiles to be coated with glaze, a glaze application and scraping mechanism 2 for applying and scraping liquid glaze, a large-size screen frame 3 for converting glaze into ceramic surface patterns, and a frame 4 for mounting the glaze application and scraping mechanism 2 and the large-size screen frame 3. The frame 4 is located above the tile conveying mechanism 1, and the glaze application and scraping mechanism 2 and the large-size screen frame 3 are respectively movably mounted on the frame 4.

[0051] This application designs a large-size screen frame, increasing the overall size of the screen frame, which is suitable for large-scale, large-size 3D glaze line fabric processes. The applied 3D patterns and textures are richer and more three-dimensional, without ghosting or deformation, and the quality is controllable.

[0052] As a further preferred embodiment, the large-size mesh frame 3 includes four frame strips 31 and a wire mesh 32 with a preset pattern. Each frame strip 31 is connected end to end to form a square frame, and the wire mesh 32 is fixed inside the square frame. Inclined connecting rods 33 are provided at the four inner corners of the square frame. Each frame strip 31 has a hollow cavity inside, and the hollow cavity is provided with an internal reinforcing rib 34 that runs through the entire hollow cavity.

[0053] This application improves the structure of the large-size screen frame 3 by designing the screen frame as a hollow structure and setting internal reinforcing ribs 34 that run through the entire hollow cavity in the hollow cavity of each frame strip 31, as well as fixing an inclined connecting rod strip 33 between two adjacent frame strips 31. This improves the rigidity and hardness of the screen frame as a whole, effectively preventing the phenomenon of pattern deformation, ghosting, and inability to reproduce due to large-area printing of enamel, and improves the durability of the large-size screen frame 3.

[0054] As a further preferred embodiment, the internal reinforcing rib 34 is composed of multiple staggered support pieces, and the cross-section of the internal reinforcing rib 34 is one of X-shaped, cross-shaped, or rice-shaped; the frame strip 31 is integrally formed with the internal reinforcing rib 34.

[0055] The thickness of the frame strip 31 and / or the inclined connecting rod strip 33 is 2-3mm, and the thickness of the internal reinforcing rib 34 is 1-2mm; the width of the frame strip 31 is 80-120mm, and the thickness is 40-50mm.

[0056] This application designs the shape of the internal reinforcing rib 34, preferably a star-shaped structure, which not only serves as the most suitable rigid reinforcement structure but also meets the tension requirements for installing wire mesh with a large span, thus saving on material costs. The integral molding process between the frame strip 31 and the internal reinforcing rib 34 can significantly improve the strength and rigidity of the overall large-size wire mesh frame 3.

[0057] In addition, the inventors optimized the thickness, width and other parameters of the frame strip 31, internal reinforcing rib 34 and inclined connecting rod strip 33, based on the rigidity requirements of large-span fabric and the cost of materials, and made the optimal parameter selection.

[0058] As a further preferred option, the wire mesh 32 has a tension ≥25N / cm. 2 The high-tensile polyester mesh 32 includes a central hollow area 321 and a surrounding dense area 322. The entire surface of the mesh 32 is coated with photosensitive emulsion. The central hollow area 321 forms a hollow pattern forming area through exposure. The planar area of ​​the hollow pattern forming area is greater than 1200mm×1200mm, and it can also be made into an extra-large size of 2800mm×4500mm.

[0059] After improvement, the wire mesh tension in this application is ≥25N / cm. 2 This ensures that the pattern will not be deformed during printing. At the same time, the screen 32 is divided into open and closed areas, which can meet the needs of pattern application and the installation space requirements of rigid structure reinforcement.

[0060] As a further preferred embodiment, the flatbed screen printing machine also includes a vacuum device 63 for vacuum negative pressure adsorption and fixation of the large-size screen frame 3, the vacuum device being mounted on the frame mounting mechanism 6.

[0061] This application uses a vacuum device to fix the large-size screen frame 3 under vacuum negative pressure, which further prevents slippage during the printing process and ensures that the pattern will not have defects such as repetition or deformation.

[0062] As a further preferred embodiment, the glaze application and scraping mechanism 2 includes a mounting frame 21, a liquid glaze conveying pipe 22, and an inclined scraper device 23. The mounting frame 21 is mounted on the frame 4, the liquid glaze conveying pipe 22 is mounted on the mounting frame 21 and spans across the ceramic conveying direction, and the inclined scraper device 23 is distributed on the horizontal side of the liquid glaze conveying pipe 22.

[0063] The glaze application and scraping mechanism 2 of this application combines the functions of glaze application and scraping printing. Two inclined scraper devices 23 are designed on both sides of the liquid glaze delivery pipe 22, which is horizontally positioned across the surface of the ceramic tile. Glaze is pumped into the liquid glaze delivery pipe 22 through a liquid delivery system and applied through multiple small openings at the bottom of the pipe. While the glaze is being applied, the inclined scraper devices 23 on one side scrape it flat and apply pressure to scrape it down to the screen 32. Through the pre-set pattern holes of the screen 32, corresponding patterns can be formed. The design and positioning of the inclined scraper devices 23 and the liquid glaze delivery pipe 22 are suitable for the efficient application of large-format ceramic pigments and glazes.

[0064] As a further preferred embodiment, the inclined scraper device 23 includes a clamping and fixing member 231 and a rubber scraper 232 disposed in the clamping and fixing member 231. The rubber scraper 232 has two pieces, which are distributed in a figure-eight shape on both sides of the liquid glaze conveying pipe 22.

[0065] In addition, the scraper of the present invention uses a rubber scraper 232 instead of a metal scraper, which to a certain extent protects the polyester wire mesh 32 of the present invention from scratches, improves the service life of the wire mesh 32, and reduces production costs.

[0066] As a further preferred embodiment, the flatbed screen printing machine also includes a support structure 5 for preventing the middle of the large-size screen frame 3 from sinking. The support structure 5 is disposed on both sides of the conveying direction of the tile conveying mechanism 1 and located below the middle of both sides of the large-size screen frame 3.

[0067] The large-size screen frame 3 of this application has a support structure 5 at the bottom of the middle section to improve the support force of the middle section of the large-size screen frame 3 and prevent insufficient support in the middle section of the frame, which would easily cause deformation and result in deformation of the applied pattern.

[0068] As a further preferred embodiment, the flatbed screen printing machine also includes a frame mounting mechanism 6 for mounting a large-size screen frame 3 and a first displacement adjustment device 7 for fine-tuning the position of the frame mounting mechanism 6 on the X / Y / Z axes.

[0069] In this application, the alignment of the large-size screen frame 3 with the ceramic body is crucial for achieving pattern consistency and repeatability in the same batch of products. This alignment can be determined by observing the overlap between the screen markings and the ceramic tile markings under transmitted light. After the first printing, the position of the large-size screen frame 3 is gradually fine-tuned using the first displacement adjustment device 7 by measuring the deviation of the pattern edge baseline.

[0070] The frame mounting mechanism 6 includes semi-frame clamping plates 61 for clamping the two sides of the large-size mesh frame 3, and a support member 62 for pressing the large-size mesh frame 3 into the semi-frame clamping plates 61. The frame mounting mechanism 6 is fixedly mounted on the first displacement adjustment device 7. The first displacement adjustment device 7 is selected from one or more combinations of pulley assembly, cylinder 71, slide rail slider assembly, and gear rack assembly 72. The large-size mesh frame 3 is mounted on the frame 4 through the first displacement adjustment device 7. Among them, the pulley assembly, cylinder 71, slide rail slider assembly, gear rack assembly 72 and other displacement adjustment devices can all adopt conventional technical means in the field. There are many combinations of the above-mentioned displacement adjustment devices, which will not be elaborated here, as long as they can achieve position adjustment in one or more directions of X / Y / Z axis.

[0071] As a further preferred embodiment, in the flatbed screen printing machine 100 applied to the 3D glaze fabric process, the flatbed screen printing machine further includes a second displacement adjustment device 8 for adjusting the position of the glaze application and scraping mechanism 2 in the X / Y / Z axes. This second displacement adjustment device is selected from one or more combinations of pulley assembly 81, cylinder 82, slide rail slider assembly, and gear rack assembly. Similar to the adjustment of the first displacement adjustment device 7, the pulley assembly 81, cylinder 82, slide rail slider assembly, gear rack assembly, and other displacement adjustment devices in this displacement adjustment device can all adopt conventional techniques in the art. The combination of the above-mentioned displacement adjustment devices can be varied, and will not be elaborated here, as long as it can achieve position adjustment in one or more directions of the X / Y / Z axes.

[0072] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
