Description

Technical Field

[0001] This utility model relates to the field of high-speed inkjet digital printing machine technology, specifically to an ink wiping device for the printhead of a high-speed inkjet digital printing machine. Background Technology

[0002] Under the major trend of digital transformation in the printing industry, high-speed inkjet digital printing presses are widely used in packaging printing, commercial printing, label printing and other fields due to their advantages such as high printing efficiency, strong personalization and customization capabilities and no need for plate making. As the core execution component of high-speed inkjet digital printing presses, the working state of the printhead directly determines the quality and precision of the printed products.

[0003] During the continuous operation of a high-speed inkjet digital printer, ink residue will inevitably appear on the printhead. When the printhead is in inkjet operation, some ink will adhere to the outer surface of the printhead nozzle due to factors such as electrostatic adsorption and air pressure fluctuations. If it is not cleaned in time, the residual ink will gradually dry and solidify over time.

[0004] Traditional printhead cleaning methods mostly involve manual wiping or wiping with a single lint-free cloth. Manual wiping is not only inefficient and difficult to adapt to the continuous operation rhythm of high-speed printing presses, but it is also prone to causing irreversible physical damage to the precision nozzles of the printhead due to uneven force and wiping angle deviations. At the same time, the consistency of manual cleaning is poor, and it is impossible to guarantee the same cleaning effect every time. The cleaning mode of a single lint-free cloth can only achieve simple surface ink removal. It is insufficient for cleaning dried and solidified ink stains and deep impurities, which can easily lead to printhead nozzle clogging, resulting in printing defects such as uneven ink spraying, broken lines, and color deviations.

[0005] According to the patent application published on the Internet, the ink wiping device for the printhead of a high-speed inkjet digital printing machine (authorization announcement number: CN219405848U) includes a "lower plate, connecting block" etc., to realize the ink wiping work.

[0006] Regarding the above description, the applicant believes the following issues exist:

[0007] The ink wiping device of the printhead of this high-speed inkjet digital printer uses a lower plate and connecting block to perform ink wiping. However, this device only uses a wiping cloth to wipe the ink, which can only achieve simple surface ink removal. It is not capable of cleaning dried and hardened ink stains and deep impurities, and it is very easy to cause printhead nozzle clogging. Therefore, this device needs to be improved.

[0017] Compared with the prior art, this utility model provides an ink wiping device for the printhead of a high-speed inkjet digital printer, which has the following beneficial effects:

[0018] 1. The ink wiping device for the printhead of this high-speed inkjet digital printer, through its designed ink wiping mechanism, allows for ink wiping of the printhead during operation. First, the printhead body is moved to the front right side of the gantry. The first and second cleanroom wipes are then slidably connected to the outer periphery of the top of the fixed platform and the outer periphery of the bottom inner side of the extension platform, respectively. At this point, the adjusting shaft can be rotated, causing the adjusting shaft to move the connecting seat and clamping plate. The clamping plate then causes the guide rod to slide inside the mounting frame. Two sets of mounting frames, connecting seats, guide rods, adjusting shafts, and clamping plates are symmetrically distributed on the left and right sides of the fixed platform, securing the first and second cleanroom wipes to ensure stability during operation. The first cleanroom wipe is located at the top of the nozzle, which can be accessed via a flexible... The tube draws cleaning fluid from the reservoir and sprays it evenly onto the surface of the first cleanroom cloth. Before wiping the ink, the bottom of the printhead body is pre-treated by wetting it. The cylinder drives the extension stage and the fixed stage to slide backward inside the bottom of the support frame and the top of the frame. The fixed stage also drives the guide frame to slide inside the support frame. When the first cleanroom cloth comes into contact with the bottom of the printhead body, the wet first cleanroom cloth softens the dried ink stains. Then the second cleanroom cloth wipes the wet printhead a second time to dry it, effectively avoiding ink stains. Compared with the design of a single cleaning cloth, the dual cleaning structure can more comprehensively remove stubborn ink stains, fiber impurities, etc. from the surface of the printhead, reduce problems such as uneven ink spraying and broken lines caused by printhead clogging, improve the clarity and color consistency of printed materials, and will not cause wear to the printhead body.

[0019] 2. The ink wiping device of the printhead of this high-speed inkjet digital printer, through the set printing mechanism, when the high-speed inkjet digital printer is in use, the first hydraulic cylinder drives the moving seat to move up and down inside the support frame, which can adjust the up and down position of the printhead body. The second hydraulic cylinder drives the moving frame to slide inside the rectangular frame and slide rail, which can move the printhead body in the back and forth direction. When moving up and down, the distance between the printhead and the printing medium and the lint-free cloth is adjusted. When moving back and forth, it is coordinated with the back and forth movement of the first and second lint-free cloths to achieve comprehensive cleaning of different areas of the printhead, improving the versatility and scene adaptability of the equipment.

[0040] Example 2

[0041] Please see Figure 1-8Furthermore, based on Embodiment 1, the printing mechanism 3 further includes a gantry frame 31, which is fixedly connected to the periphery of the frame 1. A support frame 32 is fixedly connected to the bottom inner side of the gantry frame 31. A first hydraulic cylinder 33 is fixedly connected to the top of the support frame 32. A movable seat 34 is fixedly connected to the bottom of the first hydraulic cylinder 33. The movable seat 34 is slidably connected to the inside of the support frame 32. A rectangular frame 35 is fixedly connected to the right side of the movable seat 34. Slide rails 36 are fixedly connected to the upper and lower sides of the rectangular frame 35. A second hydraulic cylinder 37 is fixedly connected to the front side of the rectangular frame 35. A movable frame 38 is fixedly connected to the rear side of the second hydraulic cylinder 37. The movable frame 38 is slidably connected to the inside of the rectangular frame 35 and the slide rails 36. A concave frame 39 is fixedly connected to the bottom right end of the movable frame 38. A nozzle body 391 is fixedly connected to the bottom inner side of the concave frame 39.

[0042] The printhead body 391 is located at the top of the frame 1, and the bottom of the printhead body 391 is in contact with the top of the first cleanroom cloth 28 and the second cleanroom cloth 29, so as to facilitate the ink wiping work on the bottom of the printhead body 391 through the first cleanroom cloth 28 and the second cleanroom cloth 29.

[0043] In actual operation, when this device is used, when the high-speed inkjet digital printer is in use, the first hydraulic cylinder 33 drives the moving seat 34 to move up and down inside the support frame 32, which can adjust the up and down position of the printhead body 391. The second hydraulic cylinder 37 drives the moving frame 38 to slide inside the rectangular frame 35 and the slide rail 36, which can move the printhead body 391 back and forth. When moving up and down, the distance between the printhead and the printing medium and the lint-free cloth is adjusted. When moving back and forth, it is coordinated with the back and forth movement of the first lint-free cloth 28 and the second lint-free cloth 29 to achieve comprehensive cleaning of different areas of the printhead, thereby improving the versatility and scene adaptability of the equipment.

[0044] When it is necessary to wipe the bottom of the printhead body 391, firstly, printing press-specific cleaning fluid is injected into the liquid storage tank 296 through the top. Then, under the action of the second hydraulic cylinder 37, the moving frame 38 and the concave frame 39 are moved forward, so that the printhead body 391 is moved to the front right side of the gantry 31. Then, under the action of the first hydraulic cylinder 33, the moving seat 34 and the rectangular frame 35 are moved downward to adjust the height of the printhead body 391 so that it is located on top of the first cleanroom cloth 28 and the second cleanroom cloth 29, and can contact the top of the first cleanroom cloth 28 and the second cleanroom cloth 29.

[0045] The first cleanroom cloth 28 and the second cleanroom cloth 29 are slidably connected to the top periphery of the fixed platform 24 and the bottom periphery of the inner side of the extension platform 23, respectively, ensuring that the two cloths are flat and wrinkle-free. At this time, the adjusting shaft 294 can be rotated, causing the adjusting shaft 294 to drive the connecting seat 292 and the clamping plate 295 to move, and causing the clamping plate 295 to drive the guide rod 293 to slide inside the mounting frame 291. The mounting frame 291, the connecting seat 292, the guide rod 293, the adjusting shaft 294 and the clamping plate 295 are provided in two sets and symmetrically distributed on the left and right sides of the fixed platform 24, which can fix the left and right sides of the first cleanroom cloth 28 and the second cleanroom cloth 29 to ensure stability during operation.

[0046] The first cleanroom cloth 28 is located at the top of the nozzle 25. Under the action of the water pump 298, the nozzle 25 can draw cleaning fluid from the liquid storage tank 296 through the hose 26 and spray it evenly onto the surface of the first cleanroom cloth 28. Before wiping the ink, the bottom of the printhead body 391 is pre-treated by wetting. Then, the cylinder 22 drives the extension platform 23 and the fixed platform 24 to slide backward inside the bottom of the support frame 21 and the top of the frame 1. The fixed platform 24 also drives the guide frame 27 to slide inside the support frame 21. When the first lint-free cloth 28 comes into contact with the bottom of the printhead body 391, the moistened cloth 28 softens the dried ink stains. Then the second lint-free cloth 29 wipes the moistened printhead dry again, effectively avoiding ink stain residue. Compared with the design of a single cleaning cloth, the dual cleaning structure can more comprehensively remove stubborn ink stains, fiber impurities and other impurities from the surface of the printhead, reduce problems such as uneven ink spraying and broken lines caused by printhead clogging, improve the clarity and color consistency of printed materials, and will not cause wear to the printhead body 391.

[0047] After cleaning is completed, the staff can take out the first cleanroom cloth 28 and the second cleanroom cloth 29 and replace them to ensure the quality of subsequent ink wiping. Under the action of the cylinder 22, the fixed stage 24 and the extension stage 23 need to be returned to their initial positions so as not to affect the working area of ​​the printhead body 391.

[0048] In use, all cylinders 22, the first hydraulic cylinder 33, and the second hydraulic cylinder 37 need to be connected to the same PLC controller near the device to achieve automated operation and parameter adjustment. The PLC controller is existing technology, and those skilled in the art are well aware of its operation method, so it will not be described in detail here.

[0049] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
