Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile printing and dyeing equipment, specifically to the ink cartridge structure of a gravure printing machine. Background Technology
[0002] In the textile printing industry, gravure printing is a relatively new printing method. Its basic principle is to use a gravure plate (i.e., a pattern engraved on a roller) to print the design, and during the printing process, the gravure plate is coated with pigment (also called ink). Currently, most gravure printing machines in the industry use open ink cartridges. To ensure clear and sharp prints, the ink spilled outside the engraved areas needs to be scraped clean. Therefore, the type of ink cartridge structure is a crucial technology for the success of a gravure printing machine and the clarity of the printed pattern. Furthermore, most ink cartridges on the market are made of aluminum alloy or stainless steel, which are prone to corrosion and other problems after prolonged use. Summary of the Invention
