Description

Technical Field

[0001] The utility model relates to the technical field of filling equipment, in particular to a filling device for ink. Background Technique

[0002] Ink is an important material for printing. It shows patterns and words on the printing substrate through printing or spraying. Ink includes main components and auxiliary components, which are evenly mixed and repeatedly rolled into a viscous colloidal fluid, consisting of resin, pigment, filler, additives and solvent, etc., and is used for various printings such as books, packaging and decoration, architectural decoration and electronic circuit boards. With the increasing social demand, the variety and output of ink have also expanded and increased accordingly. For ink, color, body (usually the rheological properties of ink such as consistency and fluidity are called the body of ink) and drying performance are the three most important properties of ink, and they should also be noted when developing ink formulations and processes and producing ink.

[0003] In the ink production process, the filling machine has become an essential equipment for each manufacturer. Most of the current filling machines do not have the functions of cleaning and filtering, and ink is a substance that is easy to precipitate, resulting in the ink being prone to solidification during the canning process. Therefore, it is necessary to stir and filter the ink before canning to improve the product quality. Content of the Utility Model
