Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of digital inkjet printers, and specifically relates to an inkjet head anti-clogging and moisture-retaining structure for digital inkjet printers. Background Technology
[0002] Digital inkjet printers are devices that transfer ink from original manuscripts such as text, pictures, photos, and anti-counterfeiting materials to the surface of materials such as paper, textiles, plastics, leather, PVC, and PC through processes such as plate making, inking, and pressurization. To prevent the printhead from clogging, a moisturizing structure is needed to keep the printhead surface moist.
[0003] Existing ink-retaining structures mostly rely on a sponge to absorb water and adhere to the printhead surface. The moisture in the sponge helps retain the ink on the printhead surface, preventing it from drying out and clogging. However, this presents several problems in practice. When the printhead and sponge are in contact, the ink on the printhead surface easily adheres to the sponge surface. If the sponge is used for a long time, the ink on the sponge surface can absorb the ink from the printhead, which can affect subsequent inkjet printing, reduce printing accuracy, and cause inconvenience to the operator. To address these issues, we propose an anti-clogging and moisture-retaining structure for the printhead of a digital inkjet printer. Utility Model Content
[0004] The purpose of this utility model is to provide an anti-clogging and moisturizing structure for the inkjet head of a digital inkjet printer.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.
[0027] Example 1:
[0028] refer to Figure 1-2 A clog-prevention and moisture-retaining structure for the inkjet head of a digital inkjet printer includes a printing structure 1 and an inkjet head body 2. A liquid collection box 7 is bolted to the side of the printing structure 1. A housing 5 is bolted to both sides of the inner cavity of the liquid collection box 7. A reset shell 15 is welded to the right side of the bottom of the inner cavity of the housing 5. A first spring 16 is welded to the left side of the reset shell 15. A sliding plate 12 is welded to the left side of the first spring 16. A push plate 3 is welded to the right side of the sliding plate 12. An insertion rod 11 is welded to the left side of the sliding plate 12. An installation rod 8 is inserted into the left side of the insertion rod 11. A sponge plate 4 is welded to the top of the installation rod 8 through to the outside of the housing 5.
[0029] Furthermore, slide rails are welded to both ends of the inner cavity of the housing 5, and both ends of the sliding plate 12 are slidably connected to the inner cavity of the slide rails. The slide rails improve the sliding stability of the sliding plate 12.
[0030] Furthermore, a support rod 9 is welded to the left side of the inner cavity of the housing 5, and a support plate 10 is welded to the right side of the support rod 9. The right side of the support plate 10 is in close contact with the left side of the mounting rod 8. The support rod 9 and the support plate 10 facilitate the support of the mounting rod 8.
[0031] Brief description of the usage process: The first spring 16 drives the sliding plate 12 to reset and move, and the sliding plate 12 drives the insertion rod 11 to reset and move. The insertion rod 11 is disengaged from the insertion hole on the surface of the mounting rod 8. At this time, the limiting pressure of the mounting rod 8 is eliminated. Then the user can remove the sponge plate 4 for maintenance and cleaning.
[0032] Example 2:
[0033] refer to Figure 1-3 A printhead anti-clogging and moisture-retaining structure for a digital inkjet printer includes a second spring 17 welded to both sides of the bottom of the inner cavity of a reset shell 15. A movable plate 18 is welded to the top of the second spring 17. A pull plate 6 is welded to the center of the bottom of the movable plate 18. A reset rod 14 is welded to the top of the movable plate 18. Through the pull plate 6, the second spring 17, the movable plate 18, and the reset rod 14, it is convenient to insert and limit the push plate 3, preventing the push plate 3 from resetting and moving during the stationary process, thereby improving the stability of the push plate 3 in use.
[0034] Furthermore, the surface of the push plate 3 is provided with an insertion hole 13, and the top of the reset rod 14 is inserted into the inner cavity of the insertion hole 13. The insertion hole 13 facilitates the insertion of the reset rod 14.
[0035] Furthermore, sliding grooves are provided on both sides of the inner cavity of the reset shell 15, and both sides of the moving plate 18 are slidably connected to the inner cavity of the sliding grooves.
[0036] Furthermore, the surface of the mounting rod 8 is provided with a socket, and the left side of the insertion rod 11 is inserted into the inner cavity of the socket, which facilitates the insertion of the insertion rod 11.
[0037] Brief description of usage: When the printhead body 2 moves to the surface of the sponge plate 4, the liquid inside the sponge plate 4 is absorbed onto the surface of the printhead body 2, effectively moisturizing the bottom of the printhead body 2. When the sponge plate 4 needs maintenance and cleaning after long-term use, the user operates the device to detach the printhead body 2 from the surface of the sponge plate 4. The user pulls the pull plate 6, which in turn moves the moving plate 18 back to its original position. The moving plate 18 then moves the second spring 17 and the reset rod 14 back to their original position. The reset rod 14 then moves out of the inner cavity of the insertion hole 13, facilitating the release of the limit on the push plate 3. At this time, the limiting pressure on the push plate 3 is eliminated, and the first spring 16 automatically resets. The first spring 16 then moves the sliding plate 12 back to its original position, which in turn moves the insertion rod 11 back to its original position. The insertion rod 11 then moves out of the insertion hole on the surface of the mounting rod 8, thus eliminating the limiting pressure on the mounting rod 8. The user can then remove the sponge plate 4 for maintenance and cleaning.
[0038] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
