Manufacturing method of wedge joint board

Abstract

The invention relates to a manufacturing method of a wedge joint board. The wedge joint board is formed by lengthwise and widthwise splicing of wedge joint slices; the wedge joint slices are cuboid eucalyptus slices with equal width and equal thickness through machining improvement treatment; the short-edge end surfaces of the wedge joint slices are provided with finger-shaped teeth with the same tooth shapes; meshed teeth are jointed to form long wedge joint strips; the long wedge joint strips are jointed by glue in parallel to form the wedge joint board. The manufacturing method comprises the following steps: A, log sawing; B, drying; C, machining improvement treatment; D, width fixing, length fixing and sorting of base materials; E, teeth combing; F, lengthwise and widthwise splicing; G, plate blank repairing, polishing and edge cutting; H, inspecting, packaging and warehousing. The manufacturing method solves the problem that fast-growing eucalyptus is easy to be shrunk and deformed when drying better; through the machining improvement treatment, the machining performance of eucalyptus is greatly improved, the polishing cost, material wastage and glue using amount are reduced, and the production cost is lowered; the manufacturing method has greater promotional value, and contains tremendous economic and social benefits.

Description

technical field [0001] The invention belongs to a wood processing method, in particular to a finger-joint board and a manufacturing method thereof for wood function improvement and wood processing technology. Background technique [0002] According to the provisions of GB / T21140-2007, finger-joined lumber refers to board squares made of sawn timber through finger-joint processing and gluing and lengthening, and then the finished board squares are glued in the width direction by glue. After knotting, it is pressed into a finger joint board. Finger-jointed wood is a material made of short and small materials glued together, so it can make use of oversized materials and make better use of inferior materials, and improve the utilization rate of wood; it is superior to solid wood in terms of physical and mechanical properties and material quality uniformity; finger-jointed boards retain It improves the material and appearance of natural wood, and can be used in various correspon...
