Description

Technical Field

[0001] The utility model relates to the field of ink production and processing, in particular to a water-based ink stirring device. Background Art

[0002] Water-based ink, flexographic water-based ink is also called liquid ink. It is mainly made of water-soluble resin, organic pigment, solvent and related additives through composite grinding. Water-based ink is particularly suitable for packaging and printing products with strict hygiene requirements such as tobacco, alcohol, food, beverage, medicine, children's toys, etc. Water-based ink is a uniform slurry composed of binders, pigments, additives and other substances. At present, the stirring device used for water-based ink processing is still a general-purpose stirring device.

[0003] Patent document CN219849116U discloses a water-based ink stirring device, which relates to the technical field of water-based ink stirring equipment, including a water-based ink stirring tank, wherein a stirring rod is movably installed inside the water-based ink stirring tank, a driving motor is arranged on the top of the stirring rod, a lifting plate is arranged on the outer side of the top of the stirring rod, and a support plate is movably connected to one end of the lifting plate. The utility model provides power through a driving motor to drive the stirring rod and the rotating column to rotate, and then the rotating column drives the rotating shaft to drive the stirring frame to rotate, and the stirring frame cooperates with the connecting column to rotate the ink to achieve the function of stirring and dispersing. While rotating, the stirring blades on the outer side of the auxiliary stirring block are forced to rotate on the outer side of the connecting column to achieve the function of auxiliary stirring, which solves the problem that the stirring mechanism cannot stir evenly and affects the working efficiency of the device, which is beneficial to increase the stirring efficiency of the device and improve the practicality of the device.
