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 theboard, 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 plate processing, in particular to a method for preparing a decorative veneer with embossing technology. Background technique [0002] With the improvement of modern people's living standards and the improvement of environmental protection awareness, the requirements for home panel decoration are getting higher and higher. The disadvantages of traditional veneer panels are that they are basically flat, and there are many times of paint construction. The large quantity not only reduces the environmental protection quality, but also lacks the natural feeling of solid wood and the three-dimensional effect of wood grain. [0003] In order to meet the needs of consumers, a brushed veneer panel with an antique relief effect has appeared on the market. This type of panel is made of wood with a specially treated surface. Feeling, so that it has a relief effect, it needs to be brushed on the surface of the wood board. [...

AI Technical Summary

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
