Description

Technical Field

[0001] The utility model relates to the technical field related to printing machines, in particular to an ink filter for a printing machine. Background Art

[0002] Ink is an important material used for printing packaging materials. It prints patterns and texts on substrates. The ink includes main ingredients and auxiliary ingredients. They are evenly mixed and repeatedly rolled to form a viscous colloidal fluid. It is composed of pigments, binders and additives. It is generally used for various printings such as books, packaging decoration, and architectural decoration. With the increase of social demand, the output of ink has also expanded and increased accordingly. Filtration is an operation in which the liquid (or gas) in the suspension (or the heat-generating gas containing solid particles) passes through the medium under the action of driving force or other external forces, and the solid particles and other substances are intercepted by the filter medium, thereby separating the solid and other substances from the liquid (or gas). The existing ink filter generally uses a filter gauze for filtering inside, and impurities accumulate on the filter gauze. The filter gauze can only be cleaned by disassembling the ink filter, which is very troublesome. Utility Model Content
