Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of colored glaze glass manufacturing, and particularly relates to a multi-pattern screen, a glass printing device and a multi-pattern screen manufacturing method. BACKGROUND

[0002] Colored glaze glass screen printing is an important method for manufacturing colored glaze glass. Since the colored glaze pattern is transferred to the glass through the screen, the manufacturing of the screen is particularly important in the colored glaze glass screen printing. Different configurations of the screen not only affect the printing quality of the colored glaze glass, but also affect the printing speed of the glass. In the existing colored glaze glass market, in order to highlight the design styles of architects and meet different application scenarios, the patterns of the colored glaze glass are increasingly diversified, and the demand for large-area colored glaze glass is greatly increased. These colored glaze glasses often cannot be directly and integrally printed, but need to be split into patterns and then spliced into an integral pattern through a large number of sub-patterns. In the prior art, only one kind of colored glaze pattern can be manufactured on one screen, and the screen needs to be replaced to change the pattern when different patterns need to be printed. On the one hand, the screen needs to be remanufactured again, such as being stretched, which increases the number of screens to be manufactured, resulting in extremely low printing efficiency. On the other hand, the process of replacing the screen also increases the repeated steps of the glass colored glaze printing, thereby slowing down the production rhythm. Moreover, in the actual printing process, if the subsequent printing is wrong, the printed screen needs to be used for re-printing, so that the screen cannot be immediately torn down and remanufactured, but needs to wait until the entire production process of the pattern is completed before being torn down and remanufactured. In the actual production process, a large number of pattern replacements make a large number of screens need to be torn down and remanufactured, which greatly slows down the printing flow rate of the colored glaze glass and seriously reduces the production efficiency, and the repeated manufacturing of the screen also increases the production cost of the colored glaze glass. SUMMARY

[0003] The main purpose of the present application is to provide a multi-pattern screen manufacturing method, which can greatly improve the utilization rate of the colored glaze glass screen.

[0004] To achieve the above-mentioned purpose, the present application provides a multi-pattern screen manufacturing method, which comprises the following steps:

[0005] Tighten the screen in the multi-pattern screen to make the screen tension F of the multi-pattern screen and the screen tension f of the single-pattern screen satisfy F-f≥3N;

[0006] Coat the blocking material on the screen of the multi-pattern screen;

[0007] Print a plurality of target patterns on the side of the screen provided with the blocking material;

[0008] Solidify the blocking material in the area not covered by the target pattern to block the screen holes of the screen not covered by the target pattern.

[0009] peeling off the blocking object covering the target pattern to expose the mesh of the screen covered by the target pattern.

[0010] In some embodiments, the screen tension F of the multi-pattern screen satisfies: 3N≤F-f≤4N, where f is the minimum screen tension of a single-pattern screen that can meet the printing requirements.

[0011] In some embodiments, the step of peeling off the blocking object covering the target pattern to expose the mesh of the screen covered by the target pattern comprises:

[0012] In some embodiments, the multi-pattern screen is washed by a high-pressure water gun to make the blocking object of the target pattern covering part fall off; wherein the pressure P of the high-pressure water gun satisfies: 100MPa≤P≤200MPa, and the minimum distance h between the water outlet of the high-pressure water gun and the multi-pattern screen satisfies: 1.5m≤h≤2m.

[0013] In some embodiments, in the step of curing the blocking object of the area not covered by the target pattern to block the mesh of the screen not covered by the target pattern, the curing time T satisfies: T-t≥40s, where t is the minimum time required for curing the blocking object of the single-pattern screen.

[0014] In some embodiments, the curing time T satisfies: 420s≤T≤440s.

[0015] The second aspect of the present application also provides a multi-pattern screen, which comprises a screen frame and a screen. The screen frame encloses a screen area. The screen is connected to the screen frame and is stretched in the screen area of the screen frame. The screen is used to print target patterns, and the tension F of the screen satisfies: F-f≥3N, where f is the minimum screen tension of a single-pattern screen that can meet the printing requirements.

[0016] In some embodiments, the multi-pattern screen has a mesh number of 120 meshes, and the tension F satisfies: 23N≤F≤25N.

[0017] In some embodiments, the multi-pattern screen has a mesh number of 200 meshes, and the tension F satisfies: 18N≤F≤22N.

[0018] In some embodiments, the multi-pattern screen has a mesh number of 250 meshes, and the tension F satisfies: 16N≤F≤18N.

[0019] In some embodiments, the adjacent boundaries of each target pattern have a minimum distance d, and the minimum distance d satisfies: 100mm≤d≤200mm.

[0020] In some embodiments, each target pattern is arranged on the screen and is spaced apart from the screen frame in a direction parallel to the plane on which the target pattern is printed, and the target pattern is spaced apart from the first interval, where the first interval is the stroke distance of the squeegee.

[0021] The third aspect of the present application also provides a glass printing device, which comprises the multi-image screen printing plate of any of the above embodiments.

[0022] Compared with the prior art, the present application has the following beneficial effects:

[0023] The multi-image screen printing plate manufacturing method of the present application sets multiple target patterns on the same screen printing plate, which on the one hand greatly reduces the number of screen printing plates required for printing colored glaze glass, thereby greatly reducing the number of times and time of screen printing plate stretching, and on the other hand, the single screen printing plate of the multi-image screen printing plate carries multiple target patterns, and the concentration of patterns greatly reduces the replacement frequency of different patterns during printing, which finally effectively improves the efficiency of screen printing. The screen tension between the multi-image screen printing plates is greater than that between the single-image screen printing plates, thereby effectively ensuring the clarity of the multiple target patterns. The present application greatly improves the utilization rate of the screen printing plate, so that the same large-scale pattern can be drawn by a small number of screen printing plates, and the number of screen printing plates is significantly reduced. The multi-image screen printing plate of the present application improves the production efficiency of colored glaze glass on the one hand, and reduces the cost of colored glaze glass screen printing plate manufacturing on the other hand, thereby greatly improving the market competitiveness of colored glaze glass.

[0037] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0038] Color glazed glass, also known as colored glazed glass, is a kind of decorative glass product with wear resistance and acid and alkali resistance, which is obtained by brushing inorganic glaze on the surface of flat glass, and then processing through drying, tempering or heat treatment to permanently sinter the glaze on the surface of the glass. Color glazed glass has high functionality and decoration. The existing glass printing mainly adopts screen printing process. Screen printing of color glazed glass refers to making a hole plate of the pattern to be printed on a screen, and transferring the glaze to the surface of the glass through the screen hole by the pressure of a squeegee, so as to form the required complete pattern. Therefore, a basic element that must be possessed in the printing of color glazed glass is a screen plate, i.e. a color glazed glass screen plate.

[0039] The production of the screen plate in the screen printing of color glazed glass is particularly important. Different configurations of the screen plate will not only affect the printing quality of the color glazed glass, but also affect the printing speed of the glass. In the existing color glazed glass market, in order to highlight the design styles of architects and meet different application scenarios, the patterns of color glazed glass are becoming more and more diversified, and the demand for large-area color glazed glass has also greatly increased. These color glazed glasses often cannot be directly printed as a whole, but need to be split into a large number of small patterns, which are then printed on the glass respectively, and the glass is spliced to obtain the complete pattern.

[0040] In the prior art, only one kind of colored glaze pattern can be made on one screen, and different patterns need to be separately made into independent screens to realize the printing of the patterns. When different patterns need to be printed on the glass, the screen needs to be replaced with a screen with the required pattern to realize the change of the pattern. In actual application process, a large-scale colored glaze glass cannot be directly printed by a single screen, and generally the overall pattern needs to be split into a large number of sub-patterns, each sub-pattern is printed on a different screen, and then the small glasses with the sub-patterns are spliced to realize the production of the large-scale colored glaze glass.

[0041] In the process of realizing the printing of the overall pattern, on the one hand, the larger the area of the colored glaze overall pattern, the more the number of screens required, which undoubtedly increases the production cost of the colored glaze glass. On the other hand, the more the number of screens used, the higher the frequency of screen replacement during printing. Since the total amount of screens is generally limited during production and processing, when the screen is replaced, it is necessary to re-produce the screen with different split patterns such as screen stretching again, which increases the number of screen stretching times, resulting in extremely low printing efficiency. And in the actual printing process, if the printing error causes part of the glass to be scrapped, the complete overall pattern cannot be spliced, at this time, the part of the glass with printing error needs to be re-drawn. In the re-drawing process, the related screen of the previous non-error needs to be used again, therefore, before enough corresponding glasses with split sub-patterns are obtained, all screens corresponding to the sub-patterns cannot be immediately torn down and re-produced, and only after the entire production process of the pattern is completed, the screen can be torn down and re-produced. In the actual production process, a large number of pattern replacements make a large number of screens need to be constantly torn down and re-produced, which greatly slows down the printing flow of the colored glaze glass, seriously reduces the production efficiency, and the repeated production of the screen also increases the production cost of the colored glaze glass.

[0042] To solve the above problems, as shown in Figure 1 The application provides a multi-pattern screen 100 production method, which comprises the following steps:

[0043] S101: The screen 120 in the multi-pattern screen 100 is stretched tightly, so that the tension F of the screen 120 of the multi-pattern screen 100 and the tension f of the screen 120 of the single-pattern screen satisfy F-f≥3N;

[0044] S102: The blocking agent 140 is coated on the screen 120 of the multi-pattern screen 100;

[0045] S103: A plurality of target patterns 130 are printed on the side of the screen 120 provided with the blocking agent 140;

[0046] S104: solidifying the blocking material 140 in the area not covered by the target pattern 130 to block the mesh holes 121 of the screen 120 not covered by the target pattern 130;

[0047] S105: peeling off the blocking material 140 covered by the target pattern 130 to expose the mesh holes 121 of the screen 120 covered by the target pattern 130.

[0048] It can be understood that in some embodiments, the screen for printing the glass enamel can also be printed with only one pattern of enamel, and in such a single-pattern screen, the minimum tension of the screen 120 in the single-pattern screen that meets the printing requirements of the enamel glass is f. Based on the minimum tension f of the screen 120 in the single-pattern screen, the tension F of the screen 120 in the multi-pattern screen 100 satisfies: F-f≥3N. It can be understood that in different embodiments, the tension F of the screen 120 in the multi-pattern screen 100 is greater than the tension of the screen 120 in the single-pattern screen by 3N to 4N. Specifically, the tension F of the screen 120 in the multi-pattern screen 100 can be greater than the minimum tension f of the single-pattern screen by 3N, 3.2N, 3.5N, 3.8N or 4N. The increase of the tension in the multi-pattern screen 100 can effectively improve the flatness of the edges of the target pattern 130 on the screen 120, so that the printed image has smooth edges, and thus the printed enamel glass can be accurately spliced.

[0049] In step S102, in some embodiments, the blocking material 140 used when coating the screen 120 of the multi-image screen printing plate 100 can be a photosensitive adhesive. Taking the photosensitive adhesive as the blocking material 140 as an example, the photosensitive adhesive is coated on the screen 120. In order to facilitate the arrangement of the target pattern 130 on the side of the screen 120 coated with the photosensitive adhesive, the photosensitive adhesive can be cured before the target pattern 130 is used to cover the photosensitive adhesive. It can be understood that in different embodiments, the type of photosensitive adhesive can be different. In order to ensure the stability of the target pattern 130 on the multi-image screen printing plate 100, the photosensitive performance of the photosensitive adhesive used on the multi-image screen printing plate 100 can be better than that of the photosensitive adhesive used on the single-image screen printing plate. It should be noted that during the coating of the photosensitive adhesive, in order to ensure that the blocking material 140 has little difference in the subsequent curing process, the photosensitive adhesive should be uniformly and continuously coated on the screen 120. That is, the coating thickness of the photosensitive adhesive on the screen 120 should meet the tolerance requirements. It can be understood that in order to facilitate the transfer of the target pattern 130, the blocking material 140 can also be dried before the multiple target patterns 130 are printed on the side of the screen 120 coated with the blocking material 140. In different embodiments, the blocking material 140 can be dried by natural drying or an oven. For the screen printing plate for building glass, the blocking material 140 is generally dried to a blocking layer by natural drying. In this application, the blocking state of each mesh hole 121 of the screen 120 refers to the state that the blocking material 140 makes each mesh hole 121 of the screen 120 closed and unable to pass the glaze.

[0050] In S103, multiple target patterns 130 are printed on the side of the screen 120 provided with the blocking material 140. In order to facilitate the description, taking the screen printing plate horizontally placed and the side coated with the blocking material 140 placed on the top as an example, the multiple target patterns 130 are printed on the side of the screen 120 provided with the blocking material 140, that is, from top to bottom, the screen printing plate is sequentially provided with the target pattern 130, the blocking material 140 and the screen 120, and the target pattern 130 covers part of the blocking material 140 and the screen 120. Before the target pattern 130 is printed on the screen 120, the overall pattern required for production is reasonably split into multiple target patterns 130, so as to realize the printing of multiple target patterns 130 on the same screen printing plate. It can be understood that in different embodiments, the overall size and shape of each target pattern 130 can be the same or different, and the splitting of the overall pattern and the combination of the target patterns 130 on the screen 120 only need to meet the arrangement of multiple target patterns 130 on the screen 120 as much as possible.

[0051] In S104, the occlusion 140 in the area not covered by the target pattern 130 is solidified, so that the mesh hole 121 of the screen 120 not covered by the target pattern 130 is closed by the occlusion. In some embodiments, the photosensitive glue can be used as the occlusion 140, and the target pattern 130 can be made of a negative film. After the screen is exposed, the photosensitive glue in the part covered by the negative film cannot be solidified, while the photosensitive glue in the part not covered by the negative film is solidified and adhered to the screen 120 due to exposure, so that the adhesion between the photosensitive glue not covered by the negative film and the screen 120 is obviously greater than the adhesion between the photosensitive glue covered by the negative film and the screen 120.

[0052] In S105, when the occlusion 140 covered by the target pattern 130 is peeled off, a high-pressure water gun can be used to wash the screen to expose the mesh hole 121 of the screen 120 covered by the target pattern 130, so as to obtain a screen in which the part covered by the target pattern 130 is not occluded by the occlusion 140. Due to solidification, the adhesion between the occlusion 140 not covered by the target pattern 130 and the screen 120 is greater, and the adhesion between the occlusion 140 covered by the target pattern 130 and the screen 120 is smaller. Under the action of the same pressure water flow, the occlusion 140 covered by the target pattern 130 is more easily taken away by the water flow. By adjusting the water pressure during washing, the separation of the occlusion 140 covered by the target pattern 130 and the occlusion 140 not covered by the target pattern 130 can be realized, so that the screen 120 has a printing pattern area not covered by the occlusion 140. During printing, the screen 120 mesh hole 121 still cannot pass through the glaze, and the glaze only passes through the screen 120 mesh hole 121 in the printing pattern area, so as to form a colored glaze pattern on the glass.

[0053] The multi-pattern screen 100 manufacturing method of the present application sets multiple target patterns 130 on the same screen, which on the one hand greatly reduces the number of screens required for printing colored glaze glass, thereby greatly reducing the number of times and time of screen stretching, and on the other hand, the single screen in the multi-pattern screen 100 carries multiple target patterns 130, and the concentration of patterns greatly reduces the replacement frequency of different patterns during printing, thereby effectively improving the efficiency of screen printing. The tension of the screen 120 between the multi-pattern screens 100 is greater than the tension of the screen 120 between the single-pattern screens, thereby effectively ensuring the clarity of the multiple target patterns 130. The present application greatly improves the utilization rate of the screen, so that the same large pattern can be drawn by a small number of screens, and the number of screen manufacturing is significantly reduced. The multi-pattern screen 100 of the present application improves the production efficiency of colored glaze glass on the one hand, and reduces the cost of colored glaze glass screen manufacturing on the other hand, improves the utilization rate of the screen, and greatly improves the market competitiveness of colored glaze glass.

[0054] In some embodiments, the cleaning of the uncured blocking material 140 under the target pattern 130 can be achieved by spraying water on the multi-pattern screen 100. Specifically, the step of peeling off the blocking material 140 under the target pattern 130 to expose the screen holes 121 of the screen 120 under the target pattern 130 in the present embodiment includes: using a high-pressure water gun to wash the multi-pattern screen 100, the pressure P of the high-pressure water gun satisfies: 100 MPa≤P≤200 MPa; the minimum distance h between the water outlet of the high-pressure water gun and the multi-pattern screen 100 satisfies: 1.5 m≤h≤2 m. It can be understood that, in order to avoid damage to the cured part of the blocking material 140 on the screen, the pressure of the high-pressure water gun should not be too large, and the specific pressure P can be 100 MPa, 150 MPa, 170 MPa or 200 MPa, etc. In order to balance the water pressure and expand the cleaning area of the high-pressure water gun, the minimum distance h between the high-pressure water gun and the water outlet can be controlled within 1.5 m to 2 m, and the specific minimum distance h can be 1.5 m, 1.6 m, 1.85 m or 2 m, which is not limited here. It can be understood that, after the target pattern 130 is developed, the blocking material 140 under the target pattern 130 needs to be peeled off to expose the screen holes 121 of the screen 120 under the target pattern 130, that is, the target pattern 130 needs to be quality checked to ensure that the obtained screen target pattern 130 is complete and does not have defects such as target image development failure, screen light leakage, and pinhole.

[0055] In some embodiments, in order to improve the adhesion between the blocking material 140 not covered by the target pattern 130 and the screen 120, the curing time of the blocking material 140 in the multi-pattern screen 100 can be extended. Specifically, in the step of curing the blocking material 140 in the area not covered by the target pattern 130 to block the screen holes 121 of the screen 120 not covered by the target pattern 130 in the present embodiment, the curing time T satisfies: T-t≥40 s, wherein t is the curing time of the single-pattern screen. Taking the photosensitive glue as an example, compared with the traditional single-pattern screen production, the curing time T of the photosensitive glue in the production process of the multi-pattern screen 100 can be 40 s to 60 s longer than the curing time t of the single-pattern screen. Specifically, the curing time T of the photosensitive glue can be 40 s, 45 s, 50 s or 60 s longer than the curing time t of the single-pattern screen, which is not limited here.

[0056] In some embodiments, in order to ensure the curing strength of the blocking material 140 not covered by the target pattern 130, the curing time T can be set as: 420 s≤T≤440 s. Specifically, the curing time T of the blocking material 140 not covered by the target pattern 130 can be 420 s, 427 s, 430 s or 440 s, which is not limited here.

[0057] The second aspect of the present application also provides a multi-image screen printing plate 100, which is made by the multi-image screen printing plate 100 manufacturing method of any of the above embodiments. As shown in Figures 2 to 4 The multi-image screen printing plate 100 includes a screen frame 110 and a screen 120. As shown in Figure 2 The screen frame 110 encloses a screen area. The screen 120 is connected to the screen frame 110 and is stretched in the screen area of the screen frame 110, and the tension F of the screen 120 satisfies: F-f≥3N. Wherein, f is the minimum tension of the screen 120 of a single-image screen printing plate with only one pattern that can meet the printing requirements. It can be understood that the screen printing plate of the present application can also include a blocking layer on the screen 120, which is made of a blocking material 140, and the blocking layer limits the target image area, and the blocking material 140 is used to block the screen 120 mesh 121 outside the target image area, so that the screen 120 mesh 121 in the target image area can pass through the colored glaze, and the part of the screen 120 covered by the blocking layer cannot pass through the colored glaze. Thanks to the improvement of the above multi-image screen printing plate 100 manufacturing method, the multi-image screen printing plate 100 of the present application can draw multiple colored glaze patterns on the same screen printing plate, which can greatly improve the efficiency of glass colored glaze screen printing 120, and on the other hand, it can also reduce the cost of glass colored glaze screen printing 120.

[0058] In different embodiments, the tension F can be different according to the different mesh of the multi-image screen printing plate 100. Specifically, in some embodiments, the mesh of the multi-image screen printing plate 100 is 120 mesh, and the tension F satisfies: 23N≤F≤25N, specifically, the tension F can be 23N, 23.5N, 24N or 25N. The mesh of the multi-image screen printing plate 100 is 200 mesh, and the tension F satisfies: 18N≤F≤22N, specifically, the tension F can be 18N, 19N, 19.5N or 22N. The mesh of the multi-image screen printing plate 100 is 250 mesh, and the tension F satisfies: 16N≤F≤18N, specifically, the tension F can be 16N, 17N or 18N, which is not limited here.

[0059] In some embodiments, in order to avoid mutual interference between the patterns on the screen frame 110, adjacent target patterns 130 can be spaced apart. As shown in Figure 3 In this embodiment, the minimum distance d between adjacent target patterns 130 satisfies: 100mm≤d≤200mm. Specifically, the minimum distance d can be 100mm, 120mm, 180mm or 200mm, which is not limited here.

[0060] In some embodiments, in order to ensure that the screen printing plate can be used for printing, as shown in Figure 3 and Figure 4As shown, the pattern can be completely printed on the glass, and there can be a certain gap between the target pattern 130 and the frame 110. In this embodiment, as... Figure 3 As shown, each target pattern 130 is disposed on the screen 120. Along a direction parallel to the plane of the screen 120 where the target pattern 130 is printed, the target pattern 130 is spaced apart from the screen frame 110 by a first interval, where the first interval is the travel distance of the scraper. Specifically, along the plane parallel to the screen 120 where the target pattern 130 is printed, there are intersecting first directions X and second directions Y. The first direction X is the scraping direction when applying enamel. The interval between the target pattern 130 and the screen frame 110 along the first direction X is the first interval D, which can be set as the travel distance of the scraper. Maintaining the first interval D1 between the target pattern 130 and the screen frame 110 ensures that the sides of the target pattern 130 near the screen frame 110 can also be coated with enamel by the scraper, thus ensuring the integrity of the target pattern 130. Along the second direction Y, the target pattern 130 can also be spaced apart from the screen frame 110 by a second interval D2, which can also be the travel distance of the scraper; this is not limited here.

[0061] A third aspect of this application also provides a glass printing apparatus (not shown in the figures), which includes the multi-image printing plate 100 of any of the above embodiments. Thanks to the improvements made to the multi-image printing plate 100, the multi-glass printing apparatus (not shown in the figures) of this embodiment has the same technical effects as the multi-image printing plate 100 described above, and will not be repeated here.

[0062] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.
