Embodiment Construction

[0013] Taking the production of integrated boards suitable for making stair treads as an example, the logs are first cut into boards by sports car band saws, main small band saws, etc.; the moisture and oil in the wood are dried out by fumigation, and after the boards are dried, pass through Double-sided planing or plane planing, pressure planing planing on both sides, and then cutting the planed boards into strips through multi-blade saws; screening the cut wood strips to select no missing wood, no blue change, no oil Cut off the wooden strips without lines, cracks, and no scars; the finished wooden strips are spliced ​​into strips with adhesives; the connected wooden strips are planed into neat square strips after four-sided planing; Press the standard square strips into the required boards through the press; plan and sand the pressed boards to the required thickness, repair and arrange them, and pack them into the warehouse.

Abstract

The invention relates to a production process of a laminated material. The production process comprises the following steps of: material preparation, sheet drying, smoothening of two sides in the thickness direction, material selection and cutting, finger-jointing in the length direction, smoothening of four sides, assembly and cold pressing, sanding and trimming, packaging of finished products and warehousing. By adopting the production process of the laminated material, sheets can be dried uniformly, and deformation, cracking and bulging of sheets can be avoided effectively. Moreover, the moisture content of the sheets is low, the drying time is short, the sheets have high bending resistance and tensile resistance, and energy can be saved effectively.

Description

technical field [0001] The invention relates to a production process of boards, in particular to a production process of laminated materials. Background technique [0002] At present, due to serious deforestation and insufficient supply of wood, its price is getting higher and higher, and the construction and decoration industries are beginning to use more wood-based panels instead of solid wood. Glulam is a kind of wood-based panel. Compared with other wood-based panels, it has stronger advantages in terms of strength, bending resistance and tensile strength. However, compared with solid wood, the glulam has a low yield and high product cost. , once a quality problem occurs, it will cause great losses. [0003] Especially in terms of cold pressing and drying of boards, the traditional air pressure jigsaw method has low pressure and the boards are prone to cracking and foaming; while the heat generated by ordinary drying furnaces is uneven and the drying speed is slow, whic...
