WEIGHT-VOLUME MIXED COLOR MATCHING METHOD FOR VEHICLE REFINISHING PAINT, MATERIAL TAKING MECHANISM, AND AUTOMATIC COLOR MIXER

摘要

A weight-volume mixing color matching method, reclamation mechanism and automatic color mixer for automobile refinishing paintings, the method comprising the following steps:(1) finding out an automobile information ID card printed with a color number on an automobile body to be refinished, finding out a color code of the automobile body or getting a close color card code through comparison, and finding out a weight formula of the refinishing paints to be used through a reader or a computer color-matching system; or using a spectrophotometer to detect coatings of the automobile body to be refinished at a position where a surface of the coatings is complete, and outputting a weight formula of the refinishing paints after calculation; (2) converting the weight formula of the refinishing paints into a corresponding volume formula of the refinishing paints according to a measured specific gravity of a color masterbatch; (3) calculating types of the required color masterbatches and volumes required for each of the color masterbatches according to the volume formula of the refinishing paints and the area to be refinished; (4) taking, by a color masterbatch dispensing mechanism and a reclamation mechanism of an automobile refinishing paint color mixer, the required color masterbatches according to the types and the volumes of the required color masterbatches.
