[0029] Screen printing is the process of transferring the pattern and text on the template to the substrate through the screen, ink scraper and ink. Screen printing has high applicability. It can print not only on flat surfaces, but also on special shapes (such as spherical surfaces); it can print not only single-color patterns, but also multi-color patterns.

[0030] See also Figures 1 to 4The present application provides an ink scraper, which can be used in screen printing to improve the defects of low printing efficiency, uneven ink addition, and low controllability of ink addition caused by the need to manually add ink step by step during the screen printing process. The ink scraper includes an ink storage box 1 and an ink scraper 2. The ink storage box 1 can be made of metal, plastic, or other materials that do not react with ink. The ink scraper 2 can be made of rubber or other materials with certain softness and rigidity, which will not scratch the screen and ensure the scraping and pressing effect of the ink scraper 2 on the ink 100. The ink storage box 1 is hollow, and a receiving chamber 11 for storing ink 100 is formed therein. An ink outlet 12 is provided at the bottom of the ink storage box 1, and the ink outlet 12 is connected to the receiving chamber 11. The ink scraper 2 is inserted into the ink outlet 12 and can seal the ink outlet 12 to prevent the ink 100 in the receiving chamber 11 from leaking from the ink outlet 12 when the ink scraper is not in use. The upper part of the ink scraper 2 is arranged in the accommodating chamber 11, and the lower part of the ink scraper 2 extends to the outside of the ink storage box 1. When the ink scraper is used for printing, the lower part of the ink scraper 2 scrapes the ink 100, so that the ink 100 is transferred to the substrate through the mesh on the screen to form a pattern or text in the template. The width of the lower part of the ink scraper 2 gradually decreases from top to bottom, and the ink scraper 2 can move along the ink outlet 12 toward the accommodating chamber 11, so that the gap between the ink scraper 2 and the ink outlet 12 gradually increases, forming an ink outlet channel 13. When the ink scraper is in use, the ink scraper 2 is subjected to the reaction force of the screen, so that the ink scraper 2 moves upward. At this time, the width of the ink scraper 2 located in the ink outlet 12 gradually decreases, so that the ink scraper 2 cannot seal the ink outlet 12. There is a gap between the two, forming an ink outlet channel 13. The ink 100 in the accommodating cavity 11 can flow downward from the ink outlet channel 13 to the screen, realizing the automatic addition of the ink 100 during the printing process, simplifying the addition of the ink 100. Since the ink scraper is generally inclined in the moving direction during printing, the ink 100 generally only flows out from one side of the forward direction of the ink scraper 2. In the above, the size of the ink outlet channel 13 can be controlled by adjusting the force of pressing down the ink storage box 1, thereby controlling the amount of ink 100 added, improving the controllability of the amount of ink 100 added, and reducing the waste of ink 100. In addition, the ink 100 is added to the screen through the ink outlet 12 along the ink scraper 2, improving the uniformity of the addition of the ink 100, thereby improving the printing efficiency and the quality of the printed product.

[0031] In the above description, the width of the ink scraper 2 refers to the length of the ink scraper 2 in a direction corresponding to the width of the ink outlet 12 .

[0032] like Figure 3As shown, the ink storage cartridge 1 includes a first side wall 1411 and a second side wall 1421, the first side wall 1411 and the second side wall 1421 are arranged to be inclined relative to each other, and the first side wall 1411 and the second side wall 1421 gradually depart from each other from bottom to top to form a accommodating cavity 11 whose width gradually increases from bottom to top; a third side wall 231 and a fourth side wall 232 are arranged at the lower part of the scraper plate 2, the third side wall 231 is arranged toward the first side wall 1411, and the fourth side wall 232 is arranged toward the second side wall 1421, the third side wall 231 and the fourth side wall 232 are respectively abutted against the inner walls of the ink outlet 12, and the distance between the third side wall 231 and the fourth side wall 232 gradually increases from bottom to top. When the ink scraper 2 moves into the accommodating chamber 11, the distance between the ink scraper 2 and the first side wall 1411 or the second side wall 1421 gradually increases, so that the ink 100 located on the upper part of the ink scraper 2 can flow downward along the gap between the ink scraper 2 and the first side wall 1411 or the second side wall 1421. By controlling the relative position of the ink scraper 2 and the ink storage box 1, the amount of ink 100 flowing downward can be controlled. When the ink scraper is not in use, the third side wall 231 and the fourth side wall 232 are respectively in contact with the side walls of the ink outlet 12. When the ink scraper 2 moves toward the accommodating chamber 11, the third side wall 231 and the fourth side wall 232 are gradually separated from the side walls of the ink outlet 12, and the distance gradually increases, forming an ink outlet channel 13, so that the ink 100 in the ink storage box 1 can flow downward along the ink scraper 2 onto the screen. The first side wall 1411 , the second side wall 1421 , the third side wall 231 and the fourth side wall 232 are arranged to be inclined, so that the ink 100 can flow smoothly, thereby improving the controllability of the amount of ink 100 added.

[0033] like Figure 3 , Figure 4 and Figure 6 As shown, the ink scraper 2 includes a connecting portion 21, a limiting portion 22 and a scraper portion 23 from top to bottom. The connecting portion 21 and the limiting portion 22 are arranged in the accommodating cavity 11. The connecting portion 21 is connected to the ink storage box 1. The edge of the limiting portion 22 abuts against the inner wall of the ink storage box 1. The scraper portion 23 is penetrated in the ink outlet 12 to seal the ink outlet 12. The connecting portion 21, the limiting portion 22 and the scraper portion 23 are integrally formed. The connecting portion 21 is protruding from the limiting portion 22, connected to the ink storage box 1, and can move up and down along the ink storage box 1 to change the relative position of the ink scraper 2 and the ink storage box 1. When the ink scraper is not in use, the edge of the limiting portion 22 abuts against the inner wall of the ink storage box 1, which can intercept the ink 100 in the ink storage box 1 and prevent the ink scraper from leaking when not in use to a certain extent. The position of the scraper portion 23 close to the limiting portion 22 is set to a rectangular shape, and the position of the scraper portion 23 away from the limiting portion 22 is set to an inverted cone shape, which not only ensures the sealing effect of the scraper portion 23 on the ink outlet 12 when the ink scraper is not in use, but also realizes the control of the ink output amount of the ink 100 by controlling the relative position of the scraper 2 and the ink outlet 12.

[0034] like Figure 6 As shown, the ink storage cartridge 1 includes a shell 14 and a connecting plate 15. A receiving chamber 11 for storing ink 100 is formed in the shell 14. The connecting plate 15 is arranged in the receiving chamber 11. The connecting plate 15 extends along the extension direction of the ink outlet 12. Both ends of the connecting plate 15 are respectively connected to the inner wall of the shell 14, and a gap is provided between at least one side of the extension direction of the connecting plate 15 and the inner wall of the shell 14, so that the ink 100 in the receiving chamber 11 can pass through the gap between the connecting plate 15 and the inner wall of the shell 14 and flow to the ink scraper 2. The connecting plate 15 is provided with a through hole, and the connecting portion 21 of the ink scraper 2 is inserted into the through hole and can move up and down along the through hole, so that when the ink scraper 2 moves upward into the accommodating chamber 11, the gap between the ink scraper 2 and the inner wall of the housing 14 gradually increases; or when the ink scraper 2 moves downward along the through hole to reset to the original position, the edge of the limiting portion 22 of the ink scraper 2 abuts against the inner wall of the housing 14, and the scraper portion 23 of the ink scraper 2 seals the ink outlet 12, so that the ink 100 in the accommodating chamber 11 no longer flows out. The connection between the ink storage box 1 and the ink scraper 2 realizes the storage and automatic addition of the ink 100, and the structure is simple.

[0035] like Figure 6 As shown, the ink scraper 2 is provided with a plurality of connecting parts 21, and the plurality of connecting parts 21 are sequentially arranged along the length direction of the ink scraper 2, which can improve the stability of the ink scraper 2 moving up and down along the via hole, thereby improving the ink discharge stability of the ink scraper and improving the printing effect of the printed matter. In practical applications, the number of connecting parts 21 can be set according to the length of the ink scraper 2. In this embodiment, three connecting parts 21 are arranged on the ink scraper 2, and each connecting part 21 is arranged at intervals.

[0036] In another embodiment, the scraper plate 2 can also be connected to the inner wall of the ink storage box 1 at both ends of the length direction of the ink outlet 12. Specifically, guide rails extending in the height direction are respectively provided on the inner side walls of the ink storage box 1 at both ends of the length direction of the ink outlet 12, and the two ends of the scraper plate 2 along the length direction of the ink outlet 12 are respectively connected to the guide rails on the inner wall of the ink storage box 1 in a one-to-one correspondence, and the scraper plate 2 can move up and down along the guide rails to open or close the ink outlet 12. Further, an elastic member 3 is also provided on the guide rail, the upper end of the elastic member 3 abuts against the top end of the guide rail, and the lower end of the elastic member 3 abuts against the upper surface of the end of the scraper plate 2, so that when printing stops, the screen no longer applies a reaction force to the scraper plate 2, and the scraper plate 2 can be restored to the initial state relatively quickly under the elastic force of the elastic member 3, thereby reducing the waste of ink 100.

[0037] like Figure 3 , Figure 4 and Figure 6As shown, the ink scraper also includes an elastic member 3, which is disposed between the limiting portion 22 of the ink scraper 2 and the connecting plate 15, and is respectively connected to the connecting portion 21 of the ink scraper 2 and the connecting plate 15, and when the elastic member 3 is stretched, it can drive the ink scraper 2 to move in a direction away from the connecting plate 15, so that the ink scraper 2 can be reset to its original position, the ink outlet 12 is sealed, and the waste of ink 100 is reduced. When the ink scraper is working, the ink scraper 2 is pressed on the screen and moves upward due to the reaction force of the screen, and the elastic member 3 is compressed by the ink scraper 2 to accumulate elastic potential energy; when the ink scraper 2 completes the printing task and is no longer pressed on the screen, the elastic member 3 releases the elastic potential energy, drives the ink scraper 2 to move downward, and automatically resets.

[0038] In some embodiments of the present application, the elastic member 3 adopts a compression spring, which is sleeved on the connecting portion 21, and one end of the compression spring abuts against the connecting plate 15, and the other end of the compression spring abuts against the limiting portion 22. The structure is simple, the cost is low, and it is easy to replace.

[0039] like Figure 3 and Figure 5 As shown, the housing 14 includes a first housing 141 and a second housing 142, which are relatively engaged and connected, and the two enclose a receiving cavity 11 for storing the ink 100. A sealing strip may be provided at the connection position of the first housing 141 and the second housing 142, which can increase the sealing performance of the housing 14 and prevent leakage of the ink 100. The connecting plate 15 is connected to the first housing 141, and the first housing 141 and the connecting plate 15 are integrally formed to improve the integrity of the housing 14.

[0040] like Figure 5 and Figure 6 As shown, the upper part of the ink storage cartridge 1 is provided with an ink adding hole 16, and a sealing cover 17 is sealed and connected to the ink adding hole 16, and the ink 100 is added to the accommodating cavity 11 through the ink adding hole 16. The ink adding hole 16 is provided on the first shell 141, and is a complete circular hole. When the sealing cover 17 seals the ink adding hole 16, it does not need to adjust the position, and it is easy to implement.

[0041] like Figure 3 and Figure 4 As shown, the inner wall of the ink storage box 1 is provided with a curved surface 18 near the ink outlet 12, and the curved surface 18 is bent toward the ink scraper 2. When the ink 100 in the accommodating cavity 11 flows downward to the curved surface 18 near the ink outlet 12, the flow rate is reduced, and the ink 100 can flow out of the ink outlet 12 more smoothly, thereby improving the stability of adding the ink 100.

[0042] In summary, the present application forms a receiving cavity capable of storing ink in the ink storage box, the ink outlet is connected to the receiving cavity, the ink scraper is disposed in the ink outlet, and the ink scraper can close the ink outlet, or the ink scraper can move along the ink outlet into the receiving cavity to open the ink outlet, so that the ink in the receiving cavity can flow downward along the gap between the inner wall of the ink outlet and the ink scraper, thereby realizing automatic addition of ink during the printing process. The ink scraper has a simple structure, and the amount of ink added can be controlled by controlling the size of the gap between the ink scraper and the inner wall of the ink outlet, thereby improving the controllability of the amount of ink added and the uniformity of ink addition, reducing ink waste, and improving printing efficiency and the quality of printed products.

[0043] In addition, when the ink scraper is used up, the scraper can be quickly reset by an elastic member arranged between the scraper and the connecting plate in the ink storage box, thereby avoiding ink leakage that affects the quality of printed products and wastes ink.

[0044] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and application concept of the present application, and all these changes or substitutions should fall within the protection scope of the claims attached to the present application.
