Embodiment 1

[0020] refer to figure 1 , a kind of pure three-layer solid wood composite floor manufacturing method provided in the present embodiment three, comprises the following steps in turn: material preparation, film inspection appearance, balance, film inspection moisture content, pressing, health preservation, stripping, film inspection bending board, repairing , sanding, wire drawing, tenoning, painting, sealing wax, off-line packaging.

[0021] Specifically, in the material preparation step: the grade of the panel is required to be C grade or D grade, and the appearance is required to be free from defects such as dark cracks and perforations, and the thickness is 3mm. The core board is a pine board processed by rotary cutting. There should be no knots in the appearance. The thickness is 9.4mm (0.4mm is the machining allowance). The whole large board is 4*4 feet. The bottom of the core board is sawed. a number of slots (see figure 2 ), the groove depth is 1 / 2 of the core plate ...

Embodiment 2

[0035] refer to figure 1 The manufacturing method of a pure three-layer solid wood composite floor provided in the second embodiment includes the following steps in turn: material preparation, inspection of appearance, balance, moisture content inspection of inspection, pressing, health preservation, stripping, inspection of bending boards, repairing , sanding, wire drawing, tenoning, painting, sealing wax, off-line packaging.

[0036] Specifically, in the material preparation step: the grade of the panel is required to be C grade or D grade, and the appearance is required to be free from defects such as dark cracks and perforations, and the thickness is 2.5mm. The core board is made of pine boards processed by rotary cutting. There should be no knots in the appearance. The thickness is 10.4mm (0.4mm is the machining allowance). The whole large board is 4*4 feet. The bottom surface of the core board is sawn. a number of slots (see figure 2 ), the groove depth is 1 / 2 of the ...

Embodiment 3

[0050] refer to figure 1 , the manufacturing method of a pure three-layer solid wood composite floor provided in the first embodiment includes the following steps in turn: material preparation, inspection of appearance, balance, moisture content inspection of inspection, pressing, health preservation, stripping, inspection of bent boards, repairing , sanding, wire drawing, tenoning, painting, sealing wax, off-line packaging.

[0051] Specifically, in the material preparation step: the grade of the panel is required to be C grade or D grade, and the appearance is required to be free from defects such as dark cracks and perforations, and the thickness is 2mm. The core board is made of pine boards processed by rotary cutting. There should be no knots in the appearance. The thickness is 11.4mm (of which 0.4mm is the processing allowance). The whole large board is 4*4 feet. The bottom of the core board is sawn. a number of slots (see figure 2 ), the groove depth is 1 / 2 of the co...

Abstract

The invention provides a manufacturing method for a pure three-layer solid wood composite floor. The manufacturing method includes the following steps of: material preparation: namely preparing a panel, a whole core board and a whole bottom board; balancing: namely balancing the moisture content; pressing and pasting: namely coating each plate with formaldehyde-free glue, and carrying out hot pressing once to form a plate blank; curing: namely pressing the plate blank with a heavy object, and curing for a plurality of days; slitting: namely cutting the plate blank into a plurality of battens; sanding: namely sanding the surfaces of the battens to be smooth; drawing: namely drawing the panel to form texture patterns; mortising: namely forming male insert-buckle type tenons and female tenon at the four sides of the battens to form a wood floor; and paint coating: namely coating the surface of the wood floor with a UV paint. Compared with a traditional three-layer or pseudo-three-layer wood floor, the pure three-layer solid wood composite floor is manufactured from a single panel, a single core board and a single bottom board; due to use of less boards, less glue is used, so the pure three-layer solid wood composite floor is more environmentally friendly; meanwhile, only a single core board is used, so the interior of the wood floor is more compact, and the deformation problems such as rib line are avoided.

Description

technical field [0001] The invention relates to the field of wood floor manufacturing, in particular to a method for manufacturing a pure three-layer solid wood composite floor. Background technique [0002] Three-layer solid wood composite flooring, including top layer, core layer and bottom layer in sequence from top to bottom. At present, the core layer of conventional three-layer flooring on the market is made of multiple solid wood strips, each of which is independent, and even composed of wooden strips of different materials, so the water between the strips Different rates and different expansion coefficients. There are gaps between the wooden strips. The stress will cause the wooden floor to deform to varying degrees and cause the surface to crack, or the surface of the wooden floor will show "rib pattern". Relatively poor stability. Also, in order to maximize profits, there are also four-layer and five-layer structures also known as three-layer wooden floors on the...
