It is widely used in circuit boards of household appliances, patterns on textiles, designs on T-shirts, T-shirts, and shoes, text on refrigerator, television, and washing machine panels, and decorations on ceramics, glass, and wall and floor tiles.

[0003] Existing screen printing uses a squeegee to apply ink. During the printing process, the squeegee moves along the surface of the screen, forcing the ink through the mesh to reach the substrate and cover the entire area of ​​the pattern to be printed.

[0004] However, as the usage time increases, the edges of the squeegee that come into contact with the screen will gradually wear down and become dull, which will lead to uneven ink transfer and affect the clarity and consistency of the printing. The squeegee needs to be replaced regularly. Utility Model Content

[0016] By incorporating a quick-release assembly, when replacing a worn screen printing squeegee, pressing a button causes the movable plate to slide on the inner surface of the cavity. This causes the outer side of the connecting rod to press against the spring in the mounting slot via the guide post, thus separating the hook from the inner side of the slot. This allows the screen printing squeegee to be quickly removed from the blade holder. When installing a new screen printing squeegee, pressing the button again causes the outer side of the connecting rod to press against the spring in the mounting slot via the guide post. Next, the slot on the connecting plate is aligned with the hook on the blade holder to engage. Releasing the button causes the connecting rod to spring back, causing the inner side of the hook to fit against the lower surface of the connecting plate, thus securing the screen printing squeegee. This quick-release assembly helps reduce downtime caused by squeegee problems, indirectly reducing maintenance costs, facilitating squeegee replacement, and improving subsequent screen printing quality and efficiency.

They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Please see Figures 1-5 The present invention provides the following two preferred embodiments: a conveying mechanism and a three-station shuttle intelligent servo screen printing machine;

[0025] Example 1:

[0026] To enable quick disassembly and assembly of the worn screen printing squeegee 12, a drive mechanism and a squeegee mechanism are fixedly installed on the upper surface of the control box 1. A quick disassembly and assembly assembly is fixedly installed on the lower surface of the squeegee mechanism. The quick disassembly and assembly assembly includes: a blade holder 10, a cavity 13 on the inner surface of the blade holder 10, a movable plate 14 slidably installed on the inner surface of the cavity 13, a connecting rod 15 fixedly installed on the outer side of the movable plate 14, and a hook 19 fixedly installed on the lower surface of the connecting rod 15. A guide post 16 is fixedly installed. A mounting groove 17 is formed on the side surface of the cavity 13. A spring 18 is fixedly connected to the bottom end of the mounting groove 17. A button 20 is fixedly connected to one end of the connecting rod 15 near the movable plate 14. A connecting plate 21 is provided on the lower surface of the tool holder 10. A slot 22 is formed on the upper surface of the connecting plate 21. A screen printing squeegee 12 is fixedly installed on the lower surface of the connecting plate 21. The connecting rod 15 is slidably connected to the cavity 13 through the movable plate 14. The spring 18 is sleeved on the guide post 16. On the outer surface, the hook 19 engages with the slot 22. By pressing the button 20, the movable plate 14 slides on the inner surface of the cavity 13, causing the outer side of the connecting rod 15 to press the spring 18 in the mounting groove 17 through the guide post 16. This causes the hook 19 to separate from the inner side of the slot 22, allowing the screen printing squeegee 12 to be quickly removed from the blade holder 10. When installing the replaced screen printing squeegee 12, pressing the button 20 causes the outer side of the connecting rod 15 to press the mounting groove 17 through the guide post 16. The spring 18 in the groove 17 then aligns the slot 22 on the connecting plate 21 with the hook 19 on the knife holder 10 to engage. When the button 20 is released, the connecting rod 15 is pushed back by the spring 18, causing the inner side of the hook 19 to fit against the lower surface of the connecting plate 21, thereby achieving the installation and fixation of the screen printing squeegee 12. Quick disassembly and assembly help reduce downtime caused by squeegee problems, indirectly reducing maintenance costs, facilitating the replacement of the screen printing squeegee 12, and improving subsequent screen printing quality and efficiency.

[0027] Example 2:

[0028] Based on Embodiment 1, in order to achieve reciprocating ink scraping on the substrate on the screen printing plate 3, a longitudinal slide 5 is fixedly installed on the inner side of the side frame 4, a servo motor 6 is fixedly installed on the outer side of the longitudinal slide 5, a sliding plate 7 is fixedly installed at the output end of the servo motor 6, the sliding plate 7 is slidably connected to the longitudinal slide 5, a mounting bracket 8 is fixedly installed on the side surface of the sliding plate 7, an electric push rod 9 is fixedly installed on the upper surface of the mounting bracket 8, the output end of the electric push rod 9 is fixedly connected to the blade holder 10, and an ink return plate 11 is fixedly installed on the lower surface of the blade holder 10.

[0029] Working principle: To achieve quick disassembly and assembly of the worn screen printing squeegee 12, pressing button 20 causes the movable plate 14 to slide on the inner surface of the cavity 13, driving the outer side of the connecting rod 15 to press the spring 18 in the mounting groove 17 through the guide post 16. This causes the hook 19 to separate from the inner side of the groove 22, allowing the screen printing squeegee 12 to be quickly removed from the squeegee holder 10. When installing the replaced screen printing squeegee 12, pressing button 20 drives the outer side of the connecting rod 15 to pass through the guide post 16. The spring 18 in the mounting groove 17 is squeezed, and then the slot 22 on the connecting plate 21 is aligned with the hook 19 on the knife holder 10 to engage. The button 20 is released, and the connecting rod 15 is pushed back by the spring 18, causing the inner side of the hook 19 to fit against the lower surface of the connecting plate 21, thereby achieving the installation and fixation of the screen printing squeegee 12. Quick disassembly and assembly help reduce downtime caused by squeegee problems, indirectly reducing maintenance costs, facilitating the replacement of the screen printing squeegee 12, and improving the subsequent screen printing quality and efficiency.
