Description

A printing module of a large UV inkjet printer

technical field

The utility model relates to a printing module of a large-scale UV inkjet printer, in particular to an adjustment device provided between the UV light projection device and the side of the base to adjust the front and rear relative positions of the UV light projection device and the base. And the printing module that delays the solidification of the ink on the surface of the printed matter is suitable for the use of large-scale UV inkjet printers.

Background technique

For the printing industry, because large-scale inkjet printers can print pictures on many different materials or thicknesses of printed matter, for a small number of diverse products, inkjet printing systems can be used for printing in a timely manner, eliminating the need to make color separations The time and work of the screen to complete the printing action quickly makes the large inkjet printer more competitive.

Among the large-scale UV inkjet printers currently on the market, there is mainly a base that can be controlled and moved back and forth on the sliding platform of the machine. There are a plurality of inkjet heads corresponding to each ink cartridge. The ink is sprayed on the printed matter through the nozzles at the bottom of the inkjet head, and then the UV light projection device fixed on the side of the base irradiates UV light vertically downward to make the ink quickly Hardened and solidified to prevent the base from touching unsolidified ink when it moves back and forth, which will affect the quality of printing.

In a conventional inkjet printer, the UV light projection device is flat-bonded and fixed on the side of the base, so that the UV light emitted by the UV light projection device is at a perpendicular angle to the surface of the printed object, and the ink is attached to the surface of the base. After printing, it will be cured by UV light. However, printed materials of different printing materials have different ink absorption speeds and UV-resistant time, and the surface structure of the printed matter will affect the time for ink droplets to form on it.

In order to achieve the best printing resolution, some printed matters need a long time to form the ink droplets at the smallest point required to form an image, and then give UV light to solidify on the surface of the printed matter. The surface tension of the ink is reduced, which increases the contact area between the surface of the printed matter and the ink, and the ink droplets must be cured by UV light in a short time to prevent the resolution of the image after the ink is solidified from being reduced, resulting in blurred images. Therefore, although the conventional method of curing ink can be applied to the occasion of printing general paper, it cannot bring into play the maximum effect, and there is still room for improvement.
