Embodiment 1

[0039] The specifications of the finished solid wood board pressed in this embodiment are thickness 10mm, length 1220mm, width 2440mm, conventional grating.

[0040] Energy-saving and environment-friendly pure solid wood non-deformation thick-core multi-layer board normal temperature pressing process, changing the traditional energy-burning hot-press forming to cold-press forming without any fuel energy. The specific process steps are as follows:

[0041] Step 1. Rotary cutting of veneer

[0042] The log is rotary cut to three whole log veneers with a thickness of 3.5mm, a length of 2440mm, and a width of 1220mm, among which the fiber direction of two veneers is vertical, and the fiber direction of the other veneer is horizontal;

[0043] Step 2. Drying

[0044] The veneer after rotary cutting is sent to the drying kiln, and dried until the moisture content of the veneer is 6%-7%, and the whole veneer with uniform water content is obtained;

[0045]Step 3: Remove scars

Abstract

The invention relates to an energy-saving environmental-friendly type pure-solid-wood non-deformation thick-core multi-layer plate normal-temperature pressing technique. The technique is characterized in that a log is processed into a veneer with the thickness being 3-5 mm in a rotary-cut mode; drying is conducted till the water content is uniform; through a breaking blade, the veneer is perpendicularly stamped from top to bottom, the cutting edge of the blade is perpendicular to the grain direction of the veneer, and growing fibers of the stamped veneer are broken; a knar removal circular cutter is positioned at the knars of the surface of the veneer correspondingly, the knars on the veneer are removed in a stamped mode from top to bottom through a stamping plate, and then holes formed after falling of the original knars are filled with filling blocks anew; the surface, needing to be compounded, of the veneer is uniformly coated with a glue layer; and the glued veneer is subjected to interlayer compounding, and cold press forming is conducted after compounding. According to the energy-saving environmental-friendly type pure-solid-wood non-deformation thick-core multi-layer plate normal-temperature pressing technique, energy is saved, and the non-poisonous, harmless, environmental-friendly and non-pollution effects are achieved; the flatness of a finished plate product is greatly improved; and deformation resistance and the flatness of the finished plate product are ensured, the solid wood effect and the appearance grade of plates are improved, and the application range of the plates is widened.

Description

technical field [0001] The invention relates to a plate processing technology, in particular to an energy-saving, environment-friendly and non-deformable pure solid wood pressing process at room temperature, and belongs to the technical field of plate processing technology. Background technique [0002] At this stage, the current market demand for high-end home improvement furniture solid wood composite panels is very good, especially for environmentally friendly solid wood panels, both in the domestic market and in the international market. [0003] At present, the traditional multi-layer solid wood board has technical problems such as difficult to control the process, unsatisfactory solid wood effect, easy deformation and warping, cracking, serious pollution, insufficient environmental protection and energy saving, and inability to carry out carving processing on the board. [0004] The traditional multi-layer solid wood board is made by processing the log into a veneer ...
