Description

Technical Field

[0001] The utility model relates to the technical field of printing supplies, in particular to a printing ink unit with a cleaning function. Background Art

[0002] Flexographic printing uses a soft and flexible printing plate, which is usually made of rubber or flexible polymer material. The printing plate surface has raised graphic parts, which transfer ink to the substrate by rotating. Flexographic printing can print on a variety of materials, including paper, plastic film, metal foil and cardboard, and is particularly suitable for non-absorbent materials.

[0003] When the flexographic printing machine is in use, the ink is absorbed by the conveying roller, and the ink is delivered to the printing material on the printing roller through the contact between the conveying roller and the printing roller for ink printing. However, since the ink has a strong adhesion, in order to prevent the ink from accumulating on the printing roller, a scraper is generally installed to scrape the ink, thereby preventing the ink from adhering to and affecting the printing efficiency of the printing roller. However, when the scraper scrapes the ink, the ink usually adheres to the scraping side of the scraper. Over time, the ink accumulated on one side of the scraper will also solidify, thereby affecting the subsequent printing work between the ink and the printed body.

[0004] Therefore, it is necessary to design a printing ink unit with a cleaning function to solve the above problems. Utility Model Content
