Description

Technical Field

[0001] This utility model relates to the field of decorative panel technology, and in particular to a bamboo and wood combined anti-deformation cabinet door panel. Background Technology

[0002] my country is rich in bamboo resources, with the world's largest variety of bamboo, bamboo forest area, and bamboo stock. Bamboo has excellent mechanical properties, including high strength, high hardness, good toughness, wear resistance, and resistance to deformation. However, due to its hollow tubular structure, it is difficult to achieve efficient processing and utilization.

[0003] The strength and rigidity of existing processed solid wood boards (especially furniture doors such as wardrobe doors and cabinet doors) are not ideal. They are prone to deformation due to changes in temperature and humidity, and are easily warped and deformed after installation. Summary of the Invention

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a bamboo-wood combined anti-deformation cabinet door panel. Bamboo is cut into bamboo strips, which are then vertically assembled to form a bamboo core. This core serves as the core of the cabinet door panel. The resulting cabinet door panel exhibits excellent bending strength, tensile strength, compressive strength, and shear strength, significantly enhancing the strength of the cabinet body and door panel. Furthermore, the sidewalls of the bamboo strips are milled into a serrated shape, allowing adjacent strips to interlock, increasing the connection area and strength between the strips and improving the overall robustness of the bamboo core.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bamboo and wood composite anti-deformation cabinet door panel, comprising a core panel, characterized in that:

[0007] The core material is bamboo core material, and the bamboo core material has a middle layer, a balancing layer and a decorative layer arranged from the inside to the outside on both sides;

[0008] The bamboo core material includes multiple bamboo strips arranged side by side; the bamboo strips include two side bamboo strips located on both sides, and multiple intermediate bamboo strips arranged between the two side bamboo strips. The side walls of the side bamboo strips facing the intermediate bamboo strips and the side walls of the intermediate bamboo strips are milled into a serrated shape, so that the side bamboo strips and the intermediate bamboo strips, as well as the adjacent intermediate bamboo strips, can mesh with each other.

[0009] Preferably, each serration is set as an equilateral triangle with a height of 2mm.

[0010] Preferably, a first adhesive layer is provided between the side bamboo strips and the middle bamboo strips, as well as between adjacent middle bamboo strips.

[0011] Preferably, the length of the bamboo strip is 2460mm~2500mm and the width is 11mm~16mm.

[0012] Preferably, a second adhesive layer is provided between the bamboo core material and the intermediate layer, the intermediate layer and the balancing layer, and the balancing layer and the decorative layer.

[0013] Preferably, the intermediate layer is made of eucalyptus or poplar.

[0014] Preferably, the balancing layer is made of engineered wood or poplar.

[0015] Preferably, the decorative layer is melamine-impregnated paper.

[0016] This utility model adopts the above-mentioned technical solution. The bamboo-wood combined anti-deformation cabinet door panel includes, from the inside out, bamboo core material, two middle layers on both sides, two balancing layers, and two decorative layers. The bamboo core material is formed by gluing and hot-pressing individual bamboo strips together. During the production process, the bamboo core material fully absorbs the physical properties of bamboo, significantly improving its bending strength, tensile strength, compressive strength, and shear strength. Therefore, the cabinet door panel made with this bamboo core material also has these advantages, and its physical properties are better than existing solid wood door panels. Furthermore, the bamboo strips are connected by equilateral triangular serrated interlocking, effectively increasing the connection area and connection strength between the bamboo strips, releasing the internal stress of the bamboo strips, and combined with the symmetrical bamboo strip panel structure, the tangential force of the bamboo strips is separated and reorganized, improving the overall strength of the bamboo core material.

[0024] like Figure 1 and 2The illustrated bamboo-wood composite anti-deformation cabinet door panel includes a core 1, which is made of bamboo core material. From the inside out, a middle layer 2, a balancing layer 3, and a decorative layer 4 are sequentially arranged on both sides of the bamboo core material. The bamboo core material includes multiple bamboo strips arranged side-by-side. Each bamboo strip includes two side bamboo strips 4 located on either side, and multiple middle bamboo strips 5 arranged between the two side bamboo strips 4. The sidewalls of the side bamboo strips 4 facing the middle bamboo strips 5 and the sidewalls of the middle bamboo strips 5 are milled into a serrated shape, thereby enabling the side bamboo strips 4 and the middle bamboo strips 5, as well as adjacent middle bamboo strips 5, to mesh with each other. In this technical solution, the bamboo-wood combined anti-deformation cabinet door panel comprises, from the inside out, bamboo core material, two middle layers on both sides, two balancing layers, and two decorative layers. The bamboo core material is formed by gluing and hot-pressing individual bamboo strips together. During production, the bamboo core material fully absorbs the physical properties of bamboo, significantly improving its bending strength, tensile strength, compressive strength, and shear strength. Therefore, cabinet door panels made with this bamboo core material also possess these advantages, exhibiting better physical properties than existing solid wood door panels. The bamboo strips are connected using a serrated interlocking mechanism, effectively increasing the connection area and strength between the strips, releasing internal stress, and enhancing the overall robustness of the bamboo core material.

[0025] Furthermore, each serration is set as an equilateral triangle with a height of 2mm.

[0026] Furthermore, a first adhesive layer is provided between the side bamboo strips 5 and the middle bamboo strips 6, as well as between adjacent middle bamboo strips 6.

[0027] Furthermore, the length of the bamboo strip is 2460mm~2500mm and the width is 11mm~16mm.

[0028] Furthermore, a second adhesive layer is provided between the bamboo core material and the intermediate layer 2, the intermediate layer 2 and the balancing layer 3, and the balancing layer 3 and the decorative layer 4.

[0029] Furthermore, the intermediate layer 2 is made of eucalyptus or poplar.

[0030] Furthermore, the balancing layer 3 is made of engineered wood or poplar wood.

[0031] Furthermore, the decorative layer 4 is melamine-impregnated adhesive film paper.

[0032] In this specific embodiment, existing cabinet door panels made of solid wood are prone to deformation due to temperature and humidity changes, resulting in warping and deformation after installation. The above solution addresses this by using bamboo core material to wrap the cabinet door panel from the inside out, with two middle layers on both sides and two decorative layers. The bamboo core material is formed by gluing and hot-pressing individual bamboo strips together. During production, the bamboo core material fully absorbs the physical properties of bamboo, significantly improving its bending strength, tensile strength, compressive strength, and shear strength. Therefore, cabinet door panels made with this bamboo core material also possess these advantages, exhibiting better physical properties than existing solid wood door panels. Furthermore, the bamboo strips are connected using equilateral triangular serrated interlocking, effectively increasing the connection area and strength between the strips, releasing internal stress, and, combined with a symmetrical bamboo strip arrangement structure, separating and recombining the tangential forces of the bamboo strips, thus improving the overall strength of the bamboo core material.

[0033] The manufacturing process of the cabinet door panel in this case is as follows:

[0034] 1. Core Material Preparation: Bamboo is pre-cut into strips 2460mm-2500mm long, 11mm-16mm wide, and the same thickness as the bamboo during its growth. The bamboo strips are coated with glue, assembled together, and then hot-pressed using a side press to form the bamboo core material.

[0035] 2. Sand the bamboo core material prepared in step 1 to make the surface of the bamboo core material smooth and free of defects.

[0036] 3. Apply glue to the sanded bamboo core material from step 2, assemble the upper and lower veneers (eucalyptus or poplar), and then perform cold pressing and hot pressing to prepare a semi-finished product;

[0037] 4. The balancing layer (engineered wood, poplar) is laminated with melamine-impregnated paper to prepare a decorative veneer.

[0038] 5. Apply glue to the semi-finished product prepared in step 3, assemble the upper and lower blanks with decorative veneer, and then perform cold pressing and hot pressing to prepare a bamboo and wood combined anti-deformation cabinet door panel.
