AI Technical Summary
In digital printing presses, white ink printheads are prone to drying and clogging when not in use, which wastes ink and reduces the lifespan of the printheads.
The design incorporates a locally independent moisturizing nozzle base plate structure, employing a lifting base plate and an independent moisturizing tray. The white ink nozzle is mounted on the lifting base plate, and moisturization of the white ink nozzle is achieved through a lifting cylinder and a return spring, preventing long-term exposure to dryness.
It effectively prevents white ink printhead clogging, reduces maintenance frequency, and extends printhead lifespan.

Abstract
Description
Technical Field
[0001] This utility model relates to an improved invention of a digital printing machine, and more particularly to an improved invention of a locally independent moisturizing nozzle base plate structure. Background Technology
[0002] In digital printing presses, there are solutions that use both white and colored inks. Due to the special composition of white ink, when producing work orders that do not include white ink, the white ink printhead is exposed to the elements for extended periods without operation. This makes it very prone to drying out and clogging the nozzles, requiring frequent maintenance, wasting ink, and reducing the lifespan of the printheads. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a local independent moisturizing nozzle base plate structure.
[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: A partially independent moisturizing nozzle base plate structure includes a nozzle base plate, on which several colored ink nozzles and white ink nozzles are provided. A large moisturizing tray is disposed below the nozzle base plate, and the large moisturizing tray cooperates with the colored ink nozzles and white ink nozzles for moisturizing. The key feature is that: a lifting small base plate is provided on the nozzle base plate, and the white ink nozzles are mounted on the lifting small base plate. The corresponding nozzle base plate has an opening for the white ink nozzles to be exposed, and the exposed white ink nozzles are at the same height as the colored ink nozzles. An independent small moisturizing tray can be inserted between the lifting small base plate and the nozzle base plate.
[0005] The lifting base plate can be lifted and lowered on several guide columns and is equipped with a lifting power source. The guide columns are fixed on the nozzle base plate, and a return spring is sleeved on the guide column. The upper end of the return spring is limited to the upper end of the guide column, and the lower end of the return spring presses against the lifting base plate.
[0006] The upper end of the guide column is provided with a frame plate, and the frame plate is provided with a lifting power source mounting plate. The lifting power source is a lifting cylinder, which is mounted on the mounting plate and is connected to the lifting base plate in a transmission manner.
[0007] The guide pillars are four in number and are located at the four corners of the lifting base plate.
[0008] The beneficial effect of this utility model is the improved local independent moisturizing nozzle base plate structure. By setting a lifting small base plate, the white ink nozzle is installed on the lifting small base plate and equipped with an independent small moisturizing plate. This avoids the white ink nozzle from being exposed to the outside for a long time when it is not working, which would cause it to dry out and clog the nozzle. This reduces nozzle maintenance and extends its service life. Attached Figure Description
[0009] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0010] Figure 1 This is a schematic diagram of the structure of the present invention. Figure 1 .
[0011] Figure 2 This is a schematic diagram of the structure of the present invention. Figure 2 . Detailed Implementation
[0012] The accompanying drawings illustrate the structure of this utility model, and further details will be described below in conjunction with the drawings. In this embodiment, see the attached drawings. Figures 1-2 This locally independent moisturizing nozzle base plate structure includes a nozzle base plate 1, on which several colored ink nozzles 2 and white ink nozzles 3 are arranged in a front-to-back pattern. A large moisturizing disc 4 is arranged below the nozzle base plate 1, which works in conjunction with the colored ink nozzles 2 and white ink nozzles 3 to moisturize them. The nozzle base plate 1 can be raised and lowered to achieve moisturization of all nozzles. A small lifting base plate 5 is provided on the nozzle base plate 1, on which the white ink nozzles 3 are mounted. The corresponding nozzle base plate 1 has an opening for the white ink nozzles 3 to be exposed, and the exposed white ink nozzles 3 are at the same height as the colored ink nozzles 2. An independent small moisturizing disc 11 can be inserted between the small lifting base plate 5 and the nozzle base plate 1.
[0013] As a further improvement, the lifting base plate 5 can be lifted and lowered on several guide columns 6 and is equipped with a lifting power source 10. The guide columns 6 are fixed on the nozzle base plate 1. A return spring 7 is sleeved on the guide column 6. The upper end of the return spring 7 is limited to the upper end of the guide column 6, and the lower end of the return spring 7 presses against the lifting base plate 5.
[0014] As a further improvement, the upper end of the guide column 6 is provided with a frame plate 8, and the frame plate 8 is provided with a lifting power source 10 mounting plate 9. The lifting power source 10 is a lifting cylinder, which is mounted on the mounting plate 9 and is connected to the lifting base plate 5. The frame plate 8 is used to stabilize the guide column 6, provide mounting space for the lifting power source 10 mounting plate 9, and avoid the rising white ink nozzle 3.
[0015] As a further improvement, four guide pillars 6 are provided and distributed at the four corners of the lifting base plate 5 to ensure lifting stability.
[0016] The working principle of this utility model is as follows: When the white ink printhead 3 is not in use, first raise the lifting base plate 5, then insert the independent small moisturizing tray 11, and then press down the lifting base plate 5. The white ink printhead 3 is in an independent moisturizing state, which can keep the printhead moist for a long time without clogging the nozzle. When the white ink printhead 3 needs to work, first raise the lifting base plate 5, take out the independent small moisturizing tray, and then press down the lifting base plate 5. The white ink printhead 3 is exposed in the printhead base plate 1 and is at the same height as other printheads, so all printheads can print normally. When the work is finished and the machine needs to be turned off, the entire printhead base plate 1 moves to the top of the large moisturizing tray 4 and then moves down to press on the large moisturizing tray 4, so all printheads are in a moisturizing state.
[0017] In summary, the above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
