The invention processes the surface of natural and scientific wood veneer with paint by mechanical production equipment, and the formed paint wood veneer is used for cladding and veneering processing. The painted veneer is finished by multiple processes of bottom coloring, primer scraping, paint coating, finish coating and the like, and has the sense of reality of natural veneer and the surface effect of the traditional paint process. The painted veneer can be processed into a roll-shaped veneer with fixed width, fixed length and unlimited fixed width, the utilization rate of the veneer can be improved, and the working efficiency of equipment can be improved. After the paint processing is carried out on the surface of the non-woven fabric at the bottom of the veneer, the veneer is more flexible, the cladding processing is easier to operate, and the cladding effect of a complex line type is more obvious. The product is suitable for various surface coating, film coating and edge sealing materials of decorative lines, section bar coating, composite door covers, composite door leaves, field decoration and the like. The paint veneer overturns the paint process of the wooden product, and the problems of the traditional paint spraying and polishing process which is continuous for more than three times at least, the production period of several days, a large amount of labor demand and occupied space are effectively solved.
Finally, it should be noted that the above embodiments are only for illustrating the technical solutions of the present invention, and not for limiting the protection scope of the present invention, although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications and equivalent substitutions can be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
