Description

Technical Field

[0001] The present application relates to the technical field of printers, and in particular to an ink leakage prevention structure. Background Art

[0002] Printers print information onto paper or other media by using printing media such as ink and toner. There are many types of printers, among which inkjet printers are more common. Since ink is used as the printing medium, an ink pad is usually provided in the printer to absorb excess ink and ensure the cleanliness of the print head.

[0003] However, during daily printing, the nozzle is prone to scattered spraying, and some ink will splash directly onto the support platform used to install the ink pad. If the ink splashed onto the support platform is not handled in time, as the ink accumulates, the ink will overflow from the edge of the support platform. If it flows to the motor or switch below, the motor or switch may burn out. Utility Model Content

[0004] The present application provides an ink leakage prevention structure, which can prevent ink from overflowing.

[0005] The present application provides an anti-ink leakage structure adopting the following technical solution:

[0006] An ink leakage prevention structure includes a supporting platform, an ink pad and a scraper. The ink pad is installed on the supporting platform. The scraper is installed on either side of the ink pad and is used to scrape off excess ink on the surface of a nozzle. A plurality of ink drainage holes are opened on the supporting platform and an ink collecting box is arranged on the bottom side. The plurality of ink drainage holes are evenly distributed on both sides of the ink pad and are used to guide the ink to the ink collecting box.

[0007] By adopting the above technical solution, when the ink is scattered and sprayed, the ink pad fails to absorb the ink. At this time, the ink is on the supporting platform, and the scraper scrapes off the excess ink on the surface of the nozzle. The ink scraped off by the scraper and the ink splashed onto the supporting platform flow into the ink collecting box from the ink holes on the supporting platform. After being collected by the ink collecting box, the ink can be prevented from overflowing, thereby providing better protection for the motor and the switch.

[0008] Optionally, there are multiple groups of ink pads and multiple scrapers, and the multiple groups of ink pads are arranged in sequence on the supporting platform and are arranged one by one corresponding to the multiple scrapers, and the ink drainage holes are opened in the gaps formed by adjacent ink pad groups.

[0009] By adopting the above technical solution, multiple groups of ink pad groups are set up to enhance the ink pad's ability to absorb ink, and ink-repellent holes are opened in the gaps formed between adjacent ink pad groups, which can better guide the ink and prevent the ink from remaining on the support platform for a long time.

[0010] Optionally, the outer edge of the supporting platform is surrounded by a stopper protrusion for preventing ink from sliding off the surface of the supporting platform.

[0011] By adopting the above technical solution, the blocking protrusion can prevent the ink from accumulating too much on the support platform and leaving the possibility of ink flowing out from the outer edge of the support platform, thereby enhancing the protection of the motor and the switch.

[0012] Optionally, a plurality of mounting plates for supporting the ink pad groups are provided on the support platform, which are arranged one-to-one corresponding to the plurality of ink pad groups, and the end faces of the mounting plates are spaced apart from the blocking protrusions to form grooves for ink flow.

[0013] By adopting the above technical solution, the mounting plate provides a position for installing the ink pad group, and is combined with the retaining protrusion to form a groove for ink flow, so that the ink can flow smoothly from the ink drainage hole into the ink collecting box.

[0014] Optionally, surfaces of the mounting plate and the supporting platform are both provided with an ink-repellent coating.

[0015] By adopting the above technical solution, the ink-repellent coating can prevent ink from adhering to the support platform and the mounting plate, thereby ensuring the cleanliness of the support platform and the mounting plate, and facilitating the ink to flow from the ink-repellent holes into the ink collecting box.

[0016] Optionally, the scraper includes a plurality of scraping blades, and the plurality of scraping blades are arranged in sequence along the length direction of the ink pad group.

[0017] By adopting the above technical solution, the scraper blades are arranged in multiple pieces, which are shorter in length compared to the longer scraper blades arranged individually. This can effectively avoid deformation of the scraper blades due to frequent use due to their excessive length, thereby increasing the service life of the scraper blades.

[0018] Optionally, a through hole and a plurality of guide grooves are provided on the scraper blade, the plurality of guide grooves are arranged along the length direction of the scraper blade and are connected with the through hole, and the through hole is opposite to the ink discharge hole.

[0019] By adopting the above technical solution, when the scraper scrapes off excess ink on the surface of the nozzle, the ink can flow along the guide groove, and the through hole is connected with the guide groove and is opposite to the ink drainage hole, so the ink can directly enter the ink drainage hole from the through hole, which fully reduces the time that the ink stays on the support platform and the mounting plate, thereby ensuring the cleanliness of the support platform and the mounting plate.

[0020] Optionally, clamping plates are provided on both sides of the scraper blade, and the two clamping plates are mounted on the mounting plate to clamp the scraper blade.

[0021] By adopting the above technical solution, the clamping plate can position the scraper blade to prevent the scraper blade from deviating along the moving direction of the nozzle when the nozzle moves and the scraper blade scrapes the ink on the surface of the nozzle.

[0022] Optionally, a sliding groove is provided on the scraper blade and can be slidably connected to the clamping plate. A positioning rod is provided between the two clamping plates. The positioning rod is inserted into the sliding groove and can be tightly connected to the clamping plates.

[0023] During the process of the scraper blade scraping the ink on the surface of the nozzle, the end of the scraper blade will be worn, resulting in the scraper blade scraping the ink effect gradually deteriorating. By adopting the above technical solution, the scraper blade is inserted into the gap between the two clamping plates and slid to adjust the extended distance of the scraper blade, and then fixed with a positioning rod to ensure the stability of the scraper blade's effect of scraping ink.

[0024] Optionally, an elastic element is provided between the two clamping plates, one end of the elastic element abuts against the mounting plate, and the other end of the elastic element abuts against the scraper blade.

[0025] By adopting the above technical solution and arranging an elastic element, the end of the scraper blade can stably abut against the surface of the nozzle, and the scraper blade can be adaptively extended and retracted to protect the nozzle and the scraper blade.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. When the ink is scattered, the ink pad fails to absorb the ink. At this time, the ink is on the support platform, and the scraper scrapes off the excess ink on the surface of the nozzle. The ink scraped off by the scraper and the ink splashed onto the support platform flow into the ink collecting box from the ink holes on the support platform. After being collected by the ink collecting box, the ink can be prevented from overflowing, and the motor and switch can be better protected.

[0028] 2. By setting up multiple groups of ink pads to enhance the ink absorption capacity of the ink pads, and the ink holes are opened in the gaps formed between adjacent ink pad groups, which can better guide the ink and prevent the ink from remaining on the support platform for a long time. The scraper blades are set into multiple groups, which are shorter in length than the individually set scraper blades. This can effectively avoid deformation of the scraper blade due to frequent use due to its excessive length, thereby increasing the service life of the scraper blade.

[0029] 3. The baffle can prevent the ink from accumulating too much on the support platform and leaving the possibility of it flowing out from the outer edge of the support platform, so as to provide better protection for the motor and the switch. The mounting plate provides a position for the installation of the ink pad group and is combined with the baffle to form a groove for the flow of ink, so that the ink can flow smoothly from the ink drainage hole into the ink collecting box.

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1 -Attached Figure 4 , further details of this application are given.

[0036] Embodiment 1:

[0037] An anti-leakage ink structure, referring to Figure 1 and Figure 2 , including a supporting platform 1 and an ink pad 2, the ink pad 2 is installed on the supporting platform 1, a plurality of ink-repelling holes 11 are opened on the supporting platform 1 and an ink collecting box 4 is arranged on the bottom side, the plurality of ink-repelling holes 11 are evenly distributed on both sides of the ink pad 2, and are used to guide the ink to the ink collecting box 4.

[0038] Furthermore, multiple groups of ink pads 2 are provided. In the present embodiment, the number of ink pad groups is 4, and each group of ink pad groups includes 6 ink pads 2, so as to more comprehensively cover the nozzle surface above the ink pads 2 and absorb ink. Multiple groups of ink pads 2 are arranged in sequence at intervals, and ink repellent holes 11 are opened in the gaps formed between adjacent ink pad groups. When the nozzle scatters and sprays directly onto the supporting platform 1, the ink can flow from the ink repellent holes 11 into the ink collecting box 4 to complete the storage of excess ink.

[0039] It should be noted that in this embodiment, the number of groups of ink pads 2 and the number of ink pads 2 in each group of ink pads are not specifically limited and can be adjusted according to the size of the supporting platform 1 .

[0040] Furthermore, a plurality of scrapers 3 are mounted on the support platform 1, which are arranged one by one corresponding to the plurality of ink pad groups. The scraper 3 is mounted on one side of the corresponding ink pad group and is tilted on the support platform 1. The end face of the scraper 3 can contact the surface of the nozzle.

[0041] When the nozzle moves, the scraper 3 located under the nozzle scrapes off the excess ink on the surface of the nozzle. Since there are multiple scrapers 3, the nozzle only needs to move the width of an ink pad group, and the scraper 3 can scrape off the excess ink on the surface of the nozzle. The ink scraped off by the scraper 3 and the ink splashed onto the supporting platform 1 flow into the ink collecting box 4 from the ink holes 11 on the supporting platform 1.

[0042] Reference Figure 1 and Figure 2 The outer edge of the supporting platform 1 is surrounded by a blocking protrusion 5. When too much ink accumulates on the supporting platform 1, the blocking protrusion 5 blocks the ink and prevents the ink from sliding off the surface of the supporting platform 1. Furthermore, the supporting platform 1 is provided with a plurality of mounting plates 6 for supporting the ink pad group, which are arranged one by one corresponding to the plurality of ink pad groups. The end faces of the mounting plates 6 are spaced apart from the blocking protrusions 5 to form grooves 20 for ink flow, so that the ink can flow smoothly from the ink drainage holes 11 into the ink collecting box 4, and the ink can be prevented from accumulating around the ink pad 2 for a long time.

[0043] In addition, the surfaces of the mounting plate 6 and the support platform 1 are provided with an ink-repellent coating 7 to prevent the ink from adhering to the support platform 1 and the mounting plate 6, thereby ensuring the cleanliness of the support platform 1 and the mounting plate 6. In this embodiment, the ink-repellent coating 7 is made of a fluorocarbon polymer (such as polytetrafluoroethylene). In other embodiments, a silicon-based hydrophobic coating or a nano-coating may also be used to prevent the ink from adhering to the mounting plate 6 and the support platform 1.

[0044] Reference Figure 1 The scraper 3 includes a plurality of scraper blades 31, and the plurality of scraper blades 31 are arranged in sequence along the length direction of the ink pad group. In the present embodiment, the number of scraper blades 31 is two. By splitting the scraper 3 into a plurality of scraper blades 31, the length of the scraper blade 31 is reduced, thereby reducing the possibility of deformation caused by frequent use of the scraper blade 31 that is too long.

[0045] Furthermore, clamping plates 8 are provided on both sides of the scraper blade 31. The two clamping plates 8 are installed on the mounting plate 6 for clamping the scraper blade 31. When installing the scraper blade 31, the scraper blade 31 is inserted into the gap formed between the two clamping plates 8 and then fastened by bolts.

[0046] The implementation principle of Example 1 of the present application is as follows: when the ink is scattered and sprayed, the ink pad 2 fails to absorb the ink. At this time, the ink is on the support platform 1, and the scraper 3 scrapes off the excess ink on the surface of the nozzle. The ink scraped off by the scraper 3 and the ink splashed onto the support platform 1 can flow in the groove 20 and flow into the ink collecting box 4 from the ink holes 11 on the support platform 1. After being collected by the ink collecting box 4, the ink can be prevented from overflowing, thereby providing better protection for the motor and the switch.

[0047] Embodiment 2:

[0048] Reference Figure 3 The difference between this embodiment 2 and embodiment 1 is that a slide groove 313 is provided on the scraper blade 31, and the slide groove 313 is provided along the width direction of the scraper blade 31. The scraper blade 31 can be slidably connected with the clamping plate 8. A positioning rod 9 is provided between the two clamping plates 8. The positioning rod 9 is inserted into the slide groove 313 and can be fastened to the clamping plate 8.

[0049] When installing the scraper 31, insert the scraper 31 into the gap formed between the two clamps 8, and then slide relative to the clamps 8 to adjust the distance that the scraper 31 extends out of the gap to compensate for the wear of the scraper 31 caused by long-term scraping against the end surface. After the end of the scraper 31 contacts the surface of the nozzle, it is finally tightened by the positioning rod 9.

[0050] In addition, a through hole 311 and a plurality of guide grooves 312 are provided on the scraper blade 31. The through hole 311 is provided along the length direction of the scraper blade 31, and the plurality of guide grooves 312 are arranged along the length direction of the scraper blade 31 and are connected with the through hole 311. The through hole 311 is opposite to the ink-repelling hole 11. When the ink is scraped off by the scraper blade 31, the ink flows along the guide groove 312 and directly enters the ink-repelling hole 11 from the through hole 311, thereby reducing the time that the ink stays on the support platform 1 and the mounting plate 6, thereby ensuring the cleanliness of the support platform 1 and the mounting plate 6.

[0051] The implementation principle of Example 2 of the present application is as follows: by providing a slide groove 313 to adjust the position of the scraper 31, it is ensured that the scraper 31 can stably scrape off excess ink on the surface of the nozzle, and by providing a through hole 311 and a guide groove 312, the ink is guided to ensure that the ink can enter the ink collecting box 4 more quickly.

[0052] Embodiment 3:

[0053] Reference Figure 4The difference between the present embodiment 3 and the embodiment 2 is that an elastic element 10 may be provided between the two clamping plates 8. The elastic element 10 is placed in the gap formed by the two clamping plates 8, and one end of the elastic element 10 abuts against the mounting plate 6, and the other end abuts against the scraper 31. In the present embodiment, the elastic element 10 is a highly elastic sponge block. In other embodiments, the elastic element 10 may also be a spring, so as to ensure that the end of the scraper 31 can contact the end face of the nozzle.

[0054] The implementation principle of Example 3 of the present application is: by setting the elastic element 10, it is ensured that the end of the scraper 31 can contact the surface of the nozzle, while the scraper 31 can shrink adaptively, thereby avoiding the need to repeatedly adjust the position of the scraper 31 according to the wear of the scraper 31.

[0055] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
