The technical difficulties of imitating the natural stone texture plate are many: 1, line texture width is stiff. When the cutter for arranging the lines on the line strips is determined, the width of the line strips on the whole line is fixed, and the line strips have no smooth change of the width of the line strips of the natural stone; and 2, toner is sprayed and filled along the CNC grain cutter grooves, the color is monotonous, the CNC grain distributing machine is limited in the types of the configured toner, one grooving cutter is only provided with one spray pipe for spraying and filling the toner, and the color powder conversion process in the same spray pipe is complex. The smooth superposition of different toner can not be realized, and the color is smoothly and gradually changed; the intersection of the texture and the substrate after the toner is sprayed and filled is not clear, the toner is scattered on the substrate through the air of the spray pipe, the toner particles are small, the weight is light, the toner scattering range is large, and the texture is permeated and scattered; 4, producing a plurality of plate products with the same texture pattern, wherein the texture effects are different from each other greatly mainly because the supply amount of toner is not stable enough; the gas pressure for conveying the toner can be fluctuated, and the like, so that the texture pattern is locally and randomly changed in color depth and width. Therefore, at the present stage, the improvement of the production technology of the CNC texture material distributor for the plate imitating the natural stone texture mainly aims to improve and break through the pigment preparation and supply technology for imitating the natural stone texture color.
