Description

Pigment grinder is used in paint production Technical Field The utility model relates to the technical field of pigment grinding, in particular to a pigment grinding device for paint production. Background The paint consists of resin, solvent, pigment, auxiliary agent and the like, in the existing paint coating production process, raw materials are required to be ground and dispersed, fineness and uniformity are important factors influencing the quality of the paint coating, the paint has great influence on film forming quality, paint film gloss, durability and storage stability of the coating, pigment grinding equipment commonly used in paint production is usually a three-roller grinder, pigment particles are sheared, extruded and ground among rollers through different rotating speeds and gaps of the three rollers, and therefore the purposes of refinement and dispersion are achieved. When the three-roller grinder in the prior art grinds pigment, the grinder usually sets up the scraper near the last stage roller, and pigment millbase scraped by the scraper can collect from the discharge seat and arrange and fall, but when a single scraper scrapes some paint materials with larger viscosity, because the cutter body needs to keep a proper distance with the roller, pigment millbase with larger viscosity is difficult to scrape from the last stage roller to lead to the scraping efficiency after pigment grinding to be influenced, for this reason, we propose a pigment grinding device for paint production. Disclosure of utility model The utility model mainly aims to provide a pigment grinding device for paint production, a pre-scraping mechanism is arranged in a chassis of a grinding machine body, a group of double-head scraping blades which can be driven by an electric push rod are arranged at an assembling position of the pre-scraping mechanism at the grinding machine body, when the grinding machine body grinds paint pigment materials with higher viscosity, the double-head scraping blades can be pushed by the electric push rod to push the pre-scraping pigment materials at a position close to a roller of the last stage of the grinding machine body as required to be discharged to a discharge seat, after pre-scraping, the residual pigment materials are thinned, the viscosity is greatly reduced, so that the original scraping blades can complete scraping and collecting work more easily and thoroughly, the pigment scraping and collecting efficiency and the cleaning degree are remarkably improved, the scraping and collecting efficiency of the grinding machine body on the pigment materials with higher viscosity is improved, and the problems in the background technology can be effectively solved.
