Dampproof solid wood floor provided with core plate proper in tightness degree

Abstract

The invention discloses a dampproof solid wood floor provided with a core plate proper in tightness degree. The floor comprises a surface plate, the core plate and a back plate, wherein the core plate is formed by series connection of multiple wood laths through at least two connecting ropes arranged in the long-side direction of the core plate. The method for manufacturing the floor comprises the steps of selecting two wood laths in the same size, conducting vacuum drying on the wood laths at a temperature ranging from 40 DEG C to 60 DEG C, and controlling the moisture content of the wood laths to be 5-8%; placing the dried wood laths in order, cutting the wood laths with a rope threading machine to obtain grooves, and pressing the connecting ropes into the grooves during cutting; fixing the surface plate and the back plate to the upper side and lower side of the manufactured core plate through adhesives respectively to obtain the solid wood floor, and applying dampproof oil to the four sides and bottom surface of the manufactured solid wood floor. Through the cooperation of a grooving device, a rope pressing device and a press-aligning plate, mechanical rope threading is achieved, grooving and rope threading are achieved synchronously, the size ratio of the grooves to the connecting ropes is proper, the tightness degree of the manufactured core plate is proper, certain redundancy is available under a damp condition, and moisture resistance is realized.

Description

technical field [0001] The invention relates to the field of floor manufacturing, in particular to a moisture-proof solid wood floor with a properly elastic core board. Background technique [0002] Most of the floors in the prior art are made of multi-layer wood boards compounded by adhesives. When making them, each layer of the multi-layer boards must be glued, so the amount of glue used is relatively large; laminate flooring is made of waste wood boards. The pieces are then glued together. Since the side walls of the adjacent wood boards between the wood chips are glued together as a whole, the large wood boards pasted into usable pieces contain a lot of glue, which will cause great pollution, and even cause excessive formaldehyde release to damage the floor. Although there is no place for glue to be used for pure solid wood flooring, the cost is too high, and many small wood strips and wood chips after processing cannot be further utilized, resulting in a large waste of ...

[0002] Most of the floors in the prior art are made of multi-layer wood boards compounded by adhesives. When making them, each layer of the multi-layer boards must be glued, so the amount of glue used is relatively large; laminate flooring is made of waste wood boards. The pieces are then glued together. Since the side walls of the adjacent wood boards between the wood chips are glued together as a whole, the large wood boards pasted into usable pieces contain a lot of glue, which will cause great pollution, and even cause excessive formaldehyde release to damage the floor. Although there is no place for glue to be used for pure solid wood flooring, the cost is too high, and many small wood strips and wood chips after processing cannot be further utilized, resulting in a large waste of raw material wood. Therefore, an environmentally friendly and raw material-saving floor Solid wood flooring is important

[0003] Chinese invention patent "CN100348811C" discloses a production method and production equipment for a three-layer solid wood composite floor with embossed locks. To make a core board, adhesives are needed for bonding during the production process of the core board. Although discarded small wood and wood chips are used, there is no technology to connect wood strips into a core board without using adhesives. It is still not conducive to environmental protection. At the same time, the adhesive connects the wooden planks in series. When the wooden planks are damp, they are squeezed by the adhesive, and their expansion and contraction margins are limited, and they are prone to deformation and are not resistant to moisture.
