Description

Technical Field

[0001] The utility model relates to the technical field of ink preparation, in particular to a filtering device for preparing printing ink. Background Art

[0002] Printing ink is a liquid material used in printers that forms text and images on paper. There are two common types of printing ink: dye ink, which is brightly colored but may fade over time; and pigment ink, which is light-resistant and water-resistant and more suitable for long-term storage. The ink is ejected through the printer nozzle and drips onto the paper to form an image.

[0003] In the process of preparing printing ink, a filtering device is needed to filter out impurities therein. Most existing filtering devices only filter the printing ink through a single-layer filtering structure, which has a poor filtering effect on the printing ink, is inconvenient to quickly clean the impurities remaining on the filtering structure, and is not convenient for subsequent maintenance. As the use time increases, the impurities remaining on the filtering structure affect the filtering efficiency of the printing ink. For this reason, we propose a filtering device for preparing printing ink. Utility Model Content
