Method for manufacturing grid artificial board core strip

Abstract

The invention discloses a method for manufacturing a grid artificial board core strip. According to the method for manufacturing the grid artificial board core strip, wooden sheet materials serve as base materials, and the wooden sheet materials are machined into comb-shaped or arched plates in the length direction of the sheet materials; the special-shaped plates are spliced in the width direction, so that special-shaped laminates with certain widths are obtained; the special-shaped laminates are glues in a mutually crossed and stacked mode in the thickness directions, wherein the included angle, in the length direction, of every two adjacent special-shaped laminates ranges from 0 degree to 90 degrees; finally, sawing is conducted in the direction parallel to the thickness direction and perpendicular to the bisector of the included angle of the axes of every two adjacent special-shaped laminate strips. When the method is used for manufacturing the artificial board core strip, the manufactured artificial board core strip is light, materials are saved, the influence of the anisotropy of wood is avoided, the artificial board has the advantages in the aspects of heat preservation and sound insulation, the method provides an important approach to utilize low-quality fast-growing wood, the economical value of the fast-growing wood is improved easily, and the development of the forestry economy and the positive cycle of the forest ecology are promoted. The method can be widely used for manufacturing cross-band veneers of artificial boards with various functions.

Description

Technical field: [0001] The invention relates to a wood product manufacturing method, in particular to a novel method for manufacturing an artificial board core board by using small-diameter fast-growing forest trees as raw materials. Background technique: [0002] At present, the widely used wood-based panel core boards are mostly made of low-quality fast-growing boards glued and spliced, and the surface is pasted with veneers to make wood products that meet people's work and life needs. This kind of product can meet people's demand for solid wood wood products and improve the economic value of fast-growing forest materials, but there are also many defects: ①The product is self-heavy. The product exists in the form of solid wood, the product is heavy, and it is inconvenient to carry and move. ②It is easy to deform. Webs made of fast-growing forest materials are prone to deformation during use due to factors such as high growth stress and obvious anisotropy of fast-growing...

AI Technical Summary

Problems solved by technology

This kind of product can meet people's demand for solid wood wood products and increase the economic value of fast-growing forest materials, but there are also many defects: ①The product is heavy

Webs made of fast-growing forest materials are prone to deformation during use due to factors such as high growth stress and obvious anisotropy of fast-growing forest materials, which affect product quality and service life

③It is not conducive to saving wood

This technology solves the problems of existing wood-based panels such as high density, large internal stress, poor stability, and large consumption of adhesives.

However, there are still problems such as the narrow range of forest raw materials and the limited width of the boards.
