Description

Technical Field

[0001] The utility model belongs to the technical field of ink processing, and in particular relates to a color paste grinding device for ink processing. Background Art

[0002] Ink is an important material used in printing. It displays patterns and texts on substrates through printing or spraying. The ink includes main components and auxiliary components, which are evenly mixed and repeatedly rolled to form a viscous colloidal fluid, which is composed of binders (resins), pigments, fillers, additives and solvents.

[0003] The three-roller mill is a commonly used equipment in ink production. The three-roller mill achieves the grinding effect through the mutual squeezing of the surfaces of three horizontal rollers and the friction at different speeds. After grinding, the material is scraped off by a scraper installed in front of the front roller.

[0004] For example, in the prior art, the Chinese utility model patent with authorization announcement number CN219984787U discloses "a three-roller grinder", which includes: a box body, which is provided with a feed opening and a discharge opening; a three-roller mechanism, which is rotatably arranged in the box body; a sliding scraper mechanism, which is arranged at the discharge opening of the box body, and the sliding scraper mechanism includes a sharp end, which is located near the outer end of the roller body of the three-roller mechanism on the side of the discharge opening, and a relative slide groove is provided on the inner wall of the box body, and the sharp end can slide along the slide groove and thus move around the outer cylindrical surface of the roller body on the side of the discharge opening.

[0005] In the prior art three-roller grinder including the one described above, a scraper installed in front of the front roller scrapes off the ground material. However, in actual use, the three rollers with different rotation speeds will all adhere to the ink raw materials to varying degrees. Although the scraper can clean the roller at the front, it cannot clean the other two rollers, which has a very high usage limitation.

[0006] In order to solve the above problems, the utility model provides a color paste grinding device for ink processing. Utility Model Content
