Description

Technical Field

[0001] This utility model relates to the field of UV printer technology, and in particular to a self-cleaning device for preventing printhead clogging in UV printers. Background Technology

[0002] A UV printer is a digital printing device based on piezoelectric inkjet technology combined with the principle of ultraviolet curing. Its core technology involves spraying special UV ink onto the surface of the substrate through a printhead, and simultaneously using a lamp to irradiate the ink to achieve instant curing, thereby completing high-precision pattern printing.

[0003] After printing, ink residue remains at the bottom of the printhead of a UV printer. If the ink is exposed for a long time, it will solidify. If the ink residue at the bottom of the printhead is not cleaned in time, the solidified ink can easily clog the nozzles of the printhead, resulting in uneven ink output. Therefore, there is an urgent need for a self-cleaning device to prevent clogging of the printhead of a UV printer. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a printhead anti-clogging self-cleaning device for a UV printer, which aims to improve the problem of ink residue at the bottom of the printhead hardening and easily clogging the nozzles.

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figure 1-4 This utility model provides an embodiment of a UV printer head anti-clogging self-cleaning device, including a printing worktable 1. A fixing plate 101 is fixedly installed on the outer wall of the printing worktable 1. An installation port 102 is opened inside the fixing plate 101. An installation frame 103 is slidably installed inside the fixing plate 101. The installation frame 103 is slidably installed inside the installation port 102. A first cleaning roller 104 and a second cleaning roller 105 are rotatably installed on the inner wall of the installation frame 103. A take-up roller 106 is arranged below the first cleaning roller 104. A discharge roller 107 is arranged below the second cleaning roller 105. A drive motor 108 is installed on the outside of the installation frame 103. The output shaft of the drive motor 108 passes through the inside of the installation frame 103 and is connected to the take-up roller 106.

[0025] Both the receiving roller 106 and the discharging roller 107 are rotatably mounted inside the mounting frame 103, and the top height of the cleaning roller 104 is higher than the top height of the mounting frame 103. A cleaning cloth 3 is provided on the outer surface of the discharging roller 107.

[0026] A support frame 5 is fixedly installed on the top of the fixed plate 101. A slide rail 51 is installed on the top of the support frame 5. A movable part 52 is slidably installed on the outer surface of the slide rail 51. A printing nozzle 53 is installed at the bottom of the movable part 52.

[0027] Specifically, the fixing plate 101 is installed on the outer wall side of the printing worktable 1, so that the support frame 5 can be fixedly installed on the top of the fixing plate 101, and the slide rail 51 is installed on the top of the support frame 5. Then, the moving part 52 can slide left and right on the outer surface of the slide rail 51, driving the bottom printing nozzle 53 to print the material placed on the top of the printing worktable 1. After the printing nozzle 53 finishes printing, the moving part 52 can drive the printing nozzle 53 to move to the top of the fixing plate 101, and the mounting frame 103 is slidably installed inside the mounting port 102. The cleaning roller 104, cleaning roller 2 105, feeding roller 107 and receiving roller 106 are installed in a rectangular array inside the mounting frame 103, and the cleaning roller 104 and cleaning roller 2 105 are located above the receiving roller 106 and feeding roller 107, respectively. The top horizontal height of the cleaning roller 104 and cleaning roller 2 105 is higher than the top horizontal height of the mounting frame 103. The cleaning cloth 3 wrapped around the outer surface of the feed roller 107 is pulled through the outer surfaces of the second cleaning roller 105 and the first cleaning roller 104, and finally rolled up to the outer surface of the take-up roller 106. When the print head 53 moves to the top of the fixed plate 101, the bottom of the print head 53 can contact the cleaning cloth 3 that has passed through the outer surfaces of the first cleaning roller 104 and the second cleaning roller 105. The drive motor 108 is powered on and starts to drive the take-up roller 106 to rotate, so that the cleaning cloth 3 is rolled up from the feed roller 107 through the second cleaning roller 105 and the first cleaning roller 104 to the outer surface of the take-up roller 106. This allows the cleaning cloth 3 to wipe and clean the ink residue at the bottom of the print head 53, preventing the residual ink from solidifying and clogging the print head 53, achieving the effect of self-cleaning the residual ink in the print head 53. After wiping, the cleaning cloth 3 can be wrapped around the outer surface of the take-up roller 106 for collection, preventing the used cleaning cloth 3 from contaminating the print head 53.

[0028] It should be noted that the moving part 52 is the moving and power component of the UV printer, which can drive the print head 53 to move on the track of the slide rail 51 to print the material on the top of the printing worktable 1. The moving part 52, the print head 53 and the slide rail 51 are all existing technologies, and their working principles are common knowledge to those skilled in the art, and will not be described in detail here.

[0029] Considering the issue that excessive contact between cleaning roller 104 and cleaning roller 2105 and the cleaning cloth 3 when wiping the bottom of the print head 53 could easily cause scratches, refer to... Figure 3 and Figure 4The outer surface of the cleaning roller 104 is provided with a groove, and an elastic element 2 is installed inside the cleaning roller 104. The bottom end of the elastic element 2 is fixedly installed on the bottom of the inner wall of the groove.

[0030] Multiple elastic elements 2 and slots are provided, and the multiple slots and elastic elements 2 are arranged in a linear array inside the cleaning roller 104. An arc-shaped plate 21 is installed at the top of the elastic element 2, and multiple arc-shaped plates 21 are provided, and the multiple arc-shaped plates 21 are arranged in a circumferential array outside the cleaning roller 104.

[0031] Specifically, multiple slots are made on the outer surface of the cleaning roller 104 so that the elastic element 2 can be vertically installed into the slot. Then, the arc plate 21 is installed on the top of the elastic element 2, and the bottom of the multiple arc plates 21 is provided with elastic elements 2. The multiple arc plates 21 are arranged in a circumferential array on the outer surface of the cleaning roller 104. Then, the cleaning cloth 3 will pass through the arc plate 21 on the outer surface of the cleaning roller 104 and be wound onto the outer surface of the take-up roller 106. When the print head 53 comes into contact with the cleaning cloth 3 for wiping, the arc plate 21 can rebound with the help of the elastic element 2 to prevent the cleaning cloth 3 from wiping the print head 53 with excessive force, causing the print head 53 to be scratched.

[0032] It should be noted that the outer surface of the second cleaning roller 105 is also provided with an elastic element 2 and an arc plate 21, so that the first cleaning roller 104 and the second cleaning roller 105 can elastically wipe the print head 53 and avoid scratching the print head 53.

[0033] Considering the varying thicknesses of the printed material and the different height adjustments required for the print head 53, the question arises regarding how cleaning roller 1 104 and cleaning roller 2 105 can contact the print heads 53 at different heights for cleaning. (Refer to...) Figure 2 A connecting plate 4 is installed at the bottom of the mounting bracket 103, an electric push rod 41 is installed at the bottom of the connecting plate 4, a support plate 42 is installed at the bottom of the electric push rod 41, and the support plate 42 is fixedly installed on the outer wall of the printing worktable 1 on the side near the printing worktable 1.

[0034] Specifically, the connecting plate 4 is fixedly installed at the bottom of the mounting frame 103, and the support plate 42 is fixedly installed on the outer side of the printing worktable 1. Then, the bottom of the electric push rod 41 can be placed on the top of the support plate 42 for fixation. Then, the top of the output rod of the electric push rod 41 is connected to the bottom of the connecting plate 4, so that the electric push rod 41 can drive the mounting frame 103 to move up and down. The cleaning roller 104 and the cleaning roller 2 105 are adjusted to the height of the printheads 53 of different heights to clean the ink residue at the bottom of the printheads 53 of different heights.

[0035] Working principle: Place the material to be printed on the top of the printing table 1, start the UV printer, and the moving part 52 can slide left and right on the outer surface of the slide rail 51, driving the bottom print head 53 to print the material placed on the top of the printing table 1. After the print head 53 finishes printing, the moving part 52 can drive the print head 53 to move to the top of the fixed plate 101. At this time, the drive motor 108 is powered on and started, driving the take-up roller 106 to rotate slowly, so that the cleaning cloth 3 passes from the feed roller 107 through the cleaning roller 2. The arc-shaped plate 21 outside 105 and the arc-shaped plate 21 outside cleaning roller 104 are rolled up to the outer surface of the take-up roller 106, so that the cleaning cloth 3 moves past the bottom of the print head 53, which can wipe and clean the ink remaining at the bottom of the print head 53, preventing the residual ink from solidifying and clogging the print head 53, achieving the effect of self-cleaning the residual ink in the print head 53. After wiping, the cleaning cloth 3 can be wrapped around the outer surface of the take-up roller 106 for collection, preventing the used cleaning cloth 3 from contaminating the print head 53.

[0036] After the print head 53 is adjusted to print materials of different thicknesses, the electric push rod 41 is powered on and can drive the mounting frame 103 to move up and down, adjusting the cleaning roller 104 and cleaning roller 2 105 to the height of the print head 53 of different heights, and cleaning the ink residue at the bottom of the print head 53 of different heights.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
