Description

Technical Field

[0001] This utility model relates to the field of screen printing equipment, specifically a protective structure for a three-station shuttle intelligent servo screen printing machine. Background Technology

[0002] Screen printing refers to the process of creating a screen printing plate with images and text using a photosensitive method, using a screen as the printing plate base. Screen printing consists of five main elements: the screen printing plate, the squeegee, the ink, the printing table, and the substrate. It utilizes the basic principle that ink can pass through the mesh openings of the screen printing plate where the image areas are open, but not where ink can pass through the non-image areas.

[0003] In conventional screen printing, ink is poured into one end of the screen printing plate, and a squeegee applies pressure to the ink area on the screen printing plate while moving at a constant speed towards the other end. During this movement, the ink is squeezed from the mesh of the image area onto the substrate by the squeegee. To prevent the ink on the screen printing plate from being exposed to the outside air, which could lead to ink contamination and reduce the printing quality of the substrate, a protective cover is usually used to protect and shield the screen printing plate.

[0004] However, in the process of screen printing, different specifications of screen printing plates need to be changed for printing different products, which means that the protective cover needs to be removed. The existing protective covers are usually fixed and inconvenient to disassemble and install, resulting in long downtime and affecting printing efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a protective structure for a three-station shuttle intelligent servo screen printing machine, so as to solve the problem mentioned in the background art that in the process of screen printing, different specifications of screen printing plates need to be replaced for printing different products, which leads to the removal of the protective cover. The existing protective covers are usually fixed, which is inconvenient to disassemble and assemble, resulting in long downtime and affecting printing efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a protective structure for a three-station shuttle-type intelligent servo screen printing machine; comprising:

[0007] The base plate has a scraping component and a fixing component fixedly installed on its upper surface. The fixing component includes an outer frame, a screen printing plate on the inner surface of the outer frame, an installation groove on the upper surface of the outer frame, a limit groove on the outer side of the outer frame, a left protective frame and a right protective frame on the inner surface of the installation groove, and an installation block fixedly installed on the lower surface of the left and right protective frames.

[0008] A slide rod is fixedly installed on the inner side of the mounting groove. A spring is sleeved on the outer surface of the slide rod. A sliding pressure plate is movably connected to one end of the slide rod. A limit block is fixedly installed on the outer side of the sliding pressure plate.

[0009] Preferably, the left protective frame and the right protective frame are engaged with the mounting slot by a mounting block.

[0010] Preferably, the sliding pressure plate slides in the mounting groove via a sliding rod, and the limiting block is slidably connected to the limiting groove.

[0011] Preferably, the upper surface of the outer frame is provided with an insertion hole, and the lower surfaces of the left and right protective frames are fixedly installed with insertion posts, which are matched with the insertion holes.

[0012] Preferably, the coating assembly includes: a stand, a horizontal slide beam fixedly installed on the inner side of the stand, and a coating mechanism slidably installed on the outer surface of the horizontal slide beam.

[0013] Preferably, a linkage column is fixedly installed on the lower surface of the coating mechanism, and an ink scraper is fixedly installed on the lower surface of the linkage column.

[0014] Preferably, the upper surfaces of the left and right protective frames are provided with sliding grooves, the linkage column slides on the inner surface of the sliding grooves, and the side wall of the right protective frame is provided with an observation window.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model proposes a protective structure for a three-station shuttle-type intelligent servo screen printing machine;

[0017] By setting up a fixing component, when replacing the screen printing stencil and disassembling the protective frame, the limiting block is pushed outward and slids on the inner surface of the limiting groove. This causes the sliding pressure plate to slide in the mounting groove, compressing the spring on the slide rod. This causes one end of the sliding pressure plate to detach from the mounting block, thus removing the protective frame. By inserting the mounting block on the lower surface of the protective frame into the mounting groove and releasing the limiting block, the spring's return causes the sliding pressure plate to lock onto the mounting block, thus installing the protective frame. This makes screen printing stencil replacement or cleaning and maintenance faster, reducing downtime and improving printing efficiency. Attached Figure Description

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.

[0025] Please see Figures 1-5 The present invention provides the following two preferred embodiments: a protective structure for a three-station shuttle intelligent servo screen printing machine;

[0026] Example 1:

[0027] To facilitate the disassembly and assembly of the protective frame when replacing the screen printing stencil 6, a scraping assembly and a fixing assembly are fixedly installed on the upper surface of the base plate 1. The fixing assembly includes: an outer frame 5, with the screen printing stencil 6 installed on the inner surface of the outer frame 5, an installation groove 8 on the upper surface of the outer frame 5, a limit groove 9 on the outer side of the outer frame 5, a sliding rod 17 fixedly installed on the inner side of the installation groove 8, a spring 18 sleeved on the outer surface of the sliding rod 17, a sliding pressure plate 19 movably connected to one end of the sliding rod 17, and a limit block 20 fixedly installed on the outer side of the sliding pressure plate 19. The left protective frame 10 and the right protective frame 11 are engaged with the installation groove 8 by the installation block 14, and the sliding pressure plate 19 is connected by... The slide bar 17 slides in the mounting groove 8, and the limiting block 20 is slidably connected to the limiting groove 9. By pushing the limiting block 20 outward, it slides on the inner surface of the limiting groove 9, causing the sliding pressure plate 19 to slide in the mounting groove 8 and compress the spring 18 on the slide bar 17. This causes one end of the sliding pressure plate 19 to detach from the mounting block 14, thus removing the protective frame. By inserting the mounting block 14 on the lower surface of the protective frame into the mounting groove 8 and releasing the limiting block 20, the spring 18 rebounds and causes the sliding pressure plate 19 to clamp the mounting block 14, thus installing the protective frame. This makes it faster to replace the screen printing plate 6 or to clean and maintain it, reducing downtime and improving printing efficiency.

[0028] Example 2:

[0029] Based on Embodiment 1, in order to protect the screen printing stencil 6 and prevent the coating on the screen printing stencil 6 from being exposed to the outside air, which would cause coating contamination and reduce the printing quality of the substrate, a left protective frame 10 and a right protective frame 11 are provided on the inner surface of the mounting groove 8. Mounting blocks 14 are fixedly installed on the lower surfaces of the left protective frame 10 and the right protective frame 11. A sliding groove 12 is opened on the upper surface of the left protective frame 10 and the right protective frame 11. The linkage column 15 slides on the inner surface of the sliding groove 12. An observation window 13 is opened on the side wall of the right protective frame 11. The coating on the screen printing stencil 6 is protected by the protective frame to prevent the coating on the screen printing stencil 6 from being exposed to the outside air, which would cause coating contamination and reduce the printing quality of the substrate.

[0030] Working principle: To facilitate the disassembly and assembly of the protective frame when replacing the screen printing stencil 6, the limiting block 20 is pushed outward to slide on the inner surface of the limiting groove 9, causing the sliding pressure plate 19 to slide in the mounting groove 8 and compress the spring 18 on the slide rod 17. This causes one end of the sliding pressure plate 19 to detach from the mounting block 14, thus removing the protective frame. By inserting the mounting block 14 on the lower surface of the protective frame into the mounting groove 8 and releasing the limiting block 20, the spring 18 rebounds and causes the sliding pressure plate 19 to lock onto the mounting block 14, thus installing the protective frame. This makes replacing the screen printing stencil 6 or cleaning and maintenance faster, reducing downtime and improving printing efficiency.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
