Description

Technical Field

[0001] The utility model relates to the technical field of grinding, in particular to an ink grinding machine. Background Art

[0002] Ink is an important material used for printing. It prints or sprays patterns and texts on substrates. Ink includes main ingredients and auxiliary ingredients, which are evenly mixed and repeatedly rolled to form a viscous colloidal fluid. Ink needs to be ground by a grinder during the production process to obtain a fine and uniform ink product. The grinder generally grinds by generating strong collision, friction, and shearing between the internal rotor and the grinding medium. The grinding medium can be a grinding rod or a grinding bead. During the grinding process, a large amount of heat will be generated due to the collision and friction of the grinding medium. In order to ensure the quality of grinding, it needs to be cooled. In the prior art, the cooling of the grinding machine is generally only to cool the surface of the grinding cylinder. For example, the utility model with the announcement number CN 213376970 U records a grinding barrel of an ink bead mill with a cooling function, including: an inner cylinder, an outer cylinder, a motor and a stirring shaft; the inner cylinder is horizontally sleeved in the outer cylinder, and one end thereof is closed and connected to the outer cylinder to form a closed end, so that a cooling channel is formed between the inner cylinder and the outer cylinder. It can be seen that the cooling channel in the patent is only the outer periphery of the inner cylinder, and a hot spot will be formed at the rotating shaft due to the inability to cool, and the high temperature of the hot spot will have an adverse effect on the quality of the heat-sensitive slurry. In addition, when the finished ink is packaged and sold or the ground color paste is transferred into the reserve tank, it can only be packaged using a packaging machine. The packaging machine must be cleaned with a solvent before use, and the packaging machine must be cleaned after use, which brings inconvenience to the packaging process. For this reason, the utility model provides an ink grinding machine to prevent the generation of heat at the rotating shaft to form a hot spot, thereby improving the cooling effect and facilitating the packaging and transfer of the color paste.
