Method for preparing embossed decorative veneer

Abstract

The invention discloses a method for preparing an embossed decorative veneer, which comprises the steps of selecting, hydrothermal softening, slicing, veneering, cold inspection, rinsing, and wire drawing, wherein the wire drawing step comprises three processes of direct drawing, sweeping and polishing; during direct drawing, a groove is formed on the surface of a board by a front steel wire roller on a wire drawing machine and grains are deepened; during sweeping, a plurality of disc brushes are arranged on the wire drawing machine, each disc brush is driven to rotate by a respective drive motor and comprises a disc and steel wires which are densely arranged on the lower end face of the disc, and the plurality of disc brushes rotate to widen the grains of the groove on the surface of the board, so that the grains on the surface of the board are wider, and the embossed effect is more vivid; and during polishing, first two groups of brushed parts of the board are polished by a rear steel wire roller on the wire drawing machine, so that a finished product has smooth feeling, and the embossed effect is achieved on the surface of the veneer. Compared with the prior art, the method ensures that wood grains are more three-dimensional, vivid and natural.

Description

Technical field [0001] The invention belongs to the field of sheet metal processing, and particularly relates to a method for preparing a decorative veneer panel with a relief technique. Background technique [0002] With the improvement of modern people's living standards and the improvement of environmental protection awareness, the requirements for home furnishings are also getting higher and higher. The disadvantage of traditional veneers is that they are basically flat surfaces, and there are many paint applications. The large quantity not only reduces the environmental protection quality, but also lacks the natural sense of solid wood and the three-dimensional effect of wood grain. [0003] In order to meet the needs of consumers, a brushed veneer with antique embossed effect appeared on the market. This kind of board is made of wood with a special surface treatment. In order to highlight the meridian effect on the surface of the wood, and the three-dimensional wood grain To...

Problems solved by technology

However, it has been proved by practice that the wire drawing effect of the above-mentioned machine on the board is not very satisfactory. After research, it is found that the reason is that the direction of rotation of the steel wire roller is along the direction of the conveyance of the wood board, and the contact surface between the wire roller and the board during the board transfer process is small , can only play the effect of scraping out the groove and deepening the grain, but the width of the grain is not enough, which makes the three-dimensional effect of wood grain look unnatural and unsatisfactory
