Description

Wood-based panel solid wood edge banding structure

technical field

The utility model relates to a wood-based panel solid wood edge-sealing structure adopting a two-step method of edge-sealing , which belongs to the field of wood product manufacturing. The two-step edge banding scheme, 1) Mill a V-shaped groove on the edge of the wood-based panel, and fill the V-shaped groove with a solid wood triangular strip that is the same as the solid wood edge banding or has a hygroscopic expansion coefficient close to that of the V-shaped groove. The surface of the groove is glued with adhesive; 2) The solid wood edge sealing material is glued to the edge of the wood-based panel with adhesive.

Background technique:

Wood-based panels are the main raw materials for panel furniture and panel wood furniture. Through veneer veneer or decorative paper veneer, furniture with a solid wood feel can be manufactured. At present, most of them use thin sheet plastic materials for edge sealing, and the edge shapes are monotonous and have no sense of solid wood. In order to enrich the appearance and visual aesthetics of panel furniture products and improve the overall quality of panel furniture products, most of them adopt the method of solid wood edge sealing, so that the edges of wood-based panel base parts form beautiful curves and curved surface decoration effects. In addition, the overall furniture The sense of solid wood has also been greatly improved. In the past, solid wood edge banding used flat or glued edge banding technology with traditional tongues. However, due to the inconsistent moisture absorption and dry shrinkage coefficients of wood-based panels and solid wood materials, this edge banding technology will increase with the indoor air humidity during the use of furniture. Because the hygroscopic expansion of the edge of the wood-based panel material is greater than that of the solid wood material, after absorbing a certain amount of moisture in the air, the two materials begin to expand, and a gap appears at the joint, and the gap is destroyed. The sealing effect of the original edge sealing has been accelerated, the intrusion speed of moisture in the air to the edge of the wood-based panel has been accelerated, the degree of hygroscopic expansion has been intensified, and uneven heights have gradually occurred at the joint between the wood-based panel and solid wood, which seriously affects the quality of furniture products. quality.

The height difference caused by the moisture absorption of solid wood edge banding has always been a difficult problem of panel furniture edge banding. There are relatively few researches at home and abroad. The difference in the height of the edge of the wood-based panel products caused by the moisture absorption after the solid wood edge sealing is caused by the different moisture absorption rate between the board and the solid wood.

Contents of the invention

The utility model proposes a wood-based panel solid wood edge-sealing structure, and its purpose is to overcome the problem that the existing wood-based panel solid wood edge-sealing absorbs the moisture in the indoor air, and the height difference appears at the junction of the wood-based panels. Realize the sealing of the edge of the wood-based panel, the edge forms a beautiful curve and surface decoration effect, and can prevent the joint between the wood-based panel and the solid wood from uneven height, that is, the surface is smooth.

The solution of the utility model: a wood-based panel solid wood edge sealing structure, including wood-based panel parts (1), solid wood triangle filling strips (2), solid wood edge sealing strips (3), characterized in that the solid wood triangle filling strips (2 ) embedded in the V-shaped groove of the wood-based panel (1), the solid wood edge banding strip (3) is attached to the side of the panel, and the surface of the V-shaped groove of the wood-based panel (1) and the solid wood triangular filling strip (2) is A The adhesive layer (4), the side of the panel and the surface of the solid wood edge banding strip (3) is the B adhesive layer (4).

The utility model adopts a two-step edge sealing scheme, that is, first milling a V-shaped groove on the edge of the wood-based panel, and filling the V-shaped groove with solid wood triangular strips that are the same as solid wood edge sealing or have a hygroscopic expansion coefficient close to that of the solid wood triangular strips. Glue the surface of the V-shaped groove with adhesive; then, glue the solid wood edge banding material to the edge of the wood-based panel with adhesive.

The beneficial effects of the utility model are: (1) the quality of wood-based edge sealing of wood-based panels is improved; (2) due to the adoption of the two-step edge sealing scheme, the solid wood triangular filling strips only need to be consistent with or similar to the hygroscopic expansion coefficient of the solid wood edge sealing material That is, there are no special requirements for other material properties, which can reduce the use of high-quality solid wood.

detailed description

A wood-based panel solid wood edge banding structure, comprising a wood-based panel (1), a solid wood triangular filling strip (2), and a solid wood edge banding strip (3), characterized in that the solid wood triangular filling strip (2) is embedded in the wood-based panel (1) In the V-shaped groove of the solid wood edge banding strip (3) is attached to the side of the board, and in the V-shaped groove of the wood-based panel (1) and on the surface of the solid wood triangular filling strip (2) is an adhesive layer (4) , the side of the panel and the surface of the solid wood edge banding (3) is the B adhesive layer (4).

The distance between the opening of the V-shaped groove and the surface of the wood-based panel 1 is about 1mm.

The V-shaped groove and the edge of the wood-based panel (1) form 60°-90°.

The corners of the solid wood triangular filling strip (2) are chamfered at 60°-90° angles.

One side of the solid wood edge banding strip (3) is plane, and the other side is curved.

Further describe the technical scheme of the utility model below in conjunction with accompanying drawing:

As shown in Figure 1, the edge of the wood-based panel (1) has a 60°～90°V-shaped groove, and the distance between the opening of the V-shaped groove and the surface of the wood-based panel should not be too large, otherwise the joint of the edge sealing cannot be guaranteed. The surface is smooth, and the distance is generally controlled at about 1mm; chamfer the corners at the 60°-90° angle of the solid wood triangular filling strip (2) to ensure that the solid wood triangular filling strip is in close contact with the surface of the V-shaped groove; the solid wood edge banding strip (3 ) one side is flat, and the other side (the arc part in the figure) can be designed arbitrarily according to product requirements; the solid wood triangular filling strip (2) should use the same tree species as the solid wood edge banding strip (3) or the one with a similar hygroscopic expansion coefficient Tree species have appearance requirements for the selection of solid wood edge banding (3), but no appearance requirements for the selection of solid wood triangular filler strips (2).
