Abstract
Description
Technical Field
[0001] This utility model relates to the field of whole-house customized furniture technology, specifically a pressed and molded skeleton cabinet door panel. Background Technology
[0002] Currently, a type of cabinet door panel with a "skeleton line" design is popular in the whole-house custom furniture industry. The cabinet door surface features a unique "skeleton line" design, using simple lines to outline the contours, enhancing the retro feel and three-dimensionality of the otherwise plain cabinet door, making the furniture look more textured. In whole-house custom design, it makes the lines of the cabinet and wall consistent, strengthens the overall space, and is suitable for modern, vintage, wabi-sabi, and light luxury styles that emphasize "line aesthetics".
[0003] Currently, the popular cabinet door panels with skeletal moldings on the market are mainly divided into two types based on their surface decoration materials and materials: one is a solid wood painted skeletal cabinet door panel (high-end), and the other is a engineered wood unpainted skeletal cabinet door panel (low-end). Regardless of the type, the product structure consists of skeletal moldings inlaid or assembled on a flat panel. The flat panels mainly include spliced panels with precious wood veneers, multi-layer solid wood boards, and unpainted engineered wood boards, etc. The skeletal moldings mainly include solid wood moldings, solid wood veneer moldings, engineered wood veneer moldings, aluminum alloy moldings, etc. (e.g., ...). Figure 6 The diagram shows the types of cabinet door structures with skeletal lines (marked 6 in the diagram represents skeletal lines). Skeleton-lined cabinet door panels have the following advantages: they are aesthetically pleasing, and their unique decorative lines give the space a sense of depth and artistry, making them suitable for various decorating styles and increasing the three-dimensionality and layering of the cabinet.
[0004] However, existing cabinet doors with skeletal molding have the following drawbacks: The manufacturing process is complex, requiring strict attention to detail, and can only be done manually or semi-mechanized, preventing industrialized, large-scale production. Therefore, their market price is high. Most importantly, the skeletal molding of these cabinet doors is achieved through 45° angle splicing, making the corner joints prone to cracking (e.g., ...). Figure 7 (As shown in Figure B, this is a location prone to cracking). Therefore, we propose a pressed-molded skeleton cabinet door panel. Summary of the Invention
[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a pressed and molded skeleton cabinet door panel to solve the difficulties of complex production process, high production cost and inability to industrialize and standardize the production of skeleton cabinet door panels at the present stage. At the same time, it solves the problem of easy cracking at the corner joints of the skeleton lines and the joint between the skeleton lines and the door core plate, which can effectively solve the problems in the background technology.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a pressed and molded skeleton cabinet door panel, comprising a skeleton front panel, a back flat panel, and a core filling board;
[0007] The skeleton panel and the back plate are symmetrically bonded to the upper and lower surfaces of the filling board. The skeleton panel, the back plate, and the filling board form an integral structure with edge banding around them. Decorative surfaces are bonded to the upper surface of the skeleton panel and the lower surface of the back plate. The skeleton panel is a pressed and molded board with skeleton lines.
[0008] Furthermore, the bone panel and the back plate are made of the same material, have the same thickness, and the same dimensions, and the shape and area of the bone panel and the back plate match the shape and area of the filler plate.
[0009] Furthermore, the bone panel and the back plate are tightly bonded to the filler plate with adhesive.
[0010] Furthermore, the decorative surface materials of the upper surface of the skeleton panel and the lower surface of the back plate are the same.
[0011] Furthermore, the decorative surface is either a painted surface or a paint-free surface.
[0012] Furthermore, the painted decorative surface is made of solid wood veneer or engineered wood veneer, and the paint-free decorative surface is made of melamine-impregnated paper or PVC film.
[0013] Further specifying, the substrate of the skeleton panel is solid wood veneer or MDF, and the core board is solid wood spliced board, solid wood multilayer board or artificial board.
[0014] Furthermore, the core filling board consists of two layers: a flat bottom layer and a flat upper layer with a linear contact surface with the bone panel. The upper and lower layers of the core filling board are bonded together with adhesive.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This pressed and molded skeleton cabinet door panel has the following advantages:
[0016] The pressed-molded frame cabinet door panels produced using new technology have a frame line that is pressed as a whole. The door core and frame line are an integral structure (without splicing gaps), eliminating the problem of cracking in the lines and door core. Furthermore, it can be mass-produced, with production costs more than 30% lower than similar products, and the quality is stable. It can produce both high-end solid wood painted frame cabinet door panels and paint-free engineered wood cabinet door panels. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figure 1-5 and Figure 8 This embodiment provides a technical solution: a pressed-molded skeleton cabinet door panel, comprising a pressed-molded skeleton panel 1, a back panel 2 of the same material, thickness, and size, and a core board 3 of the same size. The molded skeleton panel 1 and the back panel 2 of the same material, thickness, and size are symmetrically bonded to the upper and lower back surfaces of the core board 3. The upper surface is the skeleton panel 1 with skeleton lines 6, and the lower surface is the back panel 2 of the same material, thickness, and size as the upper skeleton panel. The shape and area of the upper skeleton panel 1 and the lower back panel 2 match the shape and area of the core board 3. The upper skeleton panel 1, the core board 3, and the lower back panel 2 are tightly bonded with adhesive to form an integral structure. The cut cabinet door panel is edge-banded using a fully automatic or semi-automatic edge-banding machine, forming an edge-banding strip 4 around the entire perimeter. As an integral structure, since there are no seams, cracking will not occur (e.g., Figure 7As shown in the figure, point B is the location where the existing skeleton cabinet door panel is prone to cracking. The upper skeleton panel 1 and the lower back panel 2 are also decorated with decorative surfaces 5. The upper and lower decorative surfaces 5 are made of the same material. The decorative surfaces 5 are mainly painted decorative surfaces (precious solid wood veneer, engineered wood veneer, etc.), and the surface is painted or painted-free decorative surfaces (melamine impregnated film paper, PVC film, and other paint-free materials).
[0028] The upper surface skeleton panel 1 and the lower surface back panel 2 are tightly bonded to the core board 3 with adhesive to form a single large blank panel. This can be a cabinet door of one or several sizes (one or several of the same size), or several sizes (multiple sizes of cabinet doors together). It can be cut into multiple skeleton cabinet door panels of the same or different sizes according to different size requirements (e.g., Figure 4 As shown in the diagram (point A is the cutting line), this enables industrialized and large-scale production, greatly reducing production costs and manufacturing difficulty. Because this type of cabinet door panel has a one-piece structure, it solves the problem of easy cracking at the joints of the skeleton lines, making this type of skeleton cabinet door panel more widely adaptable to the needs of whole-house custom furniture to achieve spatial integrity and match modern, vintage, wabi-sabi, and light luxury styles that emphasize "line aesthetics".
[0029] The production process of this pressed and molded skeleton cabinet door panel is as follows:
[0030] 1. Fabrication of the skeleton panel, back plate, and filler plate.
[0031] (1) Production process of skeleton panel 1: The substrate of skeleton panel 1 is mainly made of two materials. The solid wood skeleton panel uses solid wood veneer (3-5 layers of veneer) as the substrate. After gluing and assembly, the substrate is plasticized and shaped under high temperature and high pressure through the skeleton mold, thus making the skeleton board first. Then, the surface of the skeleton board is decorated with wood veneer of precious tree species, and finally the solid wood skeleton panel is made.
[0032] Another method uses MDF (3-5mm thick thin board) as the base material. After softening, the base material is plasticized and shaped under high temperature and pressure using a bone mold to make a bone board. Then, the surface of the bone board is finished with melamine-impregnated paper or PVC and other paint-free decorative materials to finally make a paint-free bone panel.
[0033] (2) Production process of core board 3: Solid wood frame cabinet door panel is made of solid wood splicing board or solid wood multilayer board as core board 3, and paint-free frame cabinet door panel is made of particleboard (chipboard), MDF, OSB and other artificial boards as core board 3.
[0034] The core board 3 has the same specifications, dimensions and shape as the skeleton panel 1. The core board 3 is composed of two layers. The bottom layer is a flat plate, and the upper layer has a flat line on the linear contact surface with the skeleton panel 1. The upper and lower layers of the core board 3 are bonded together with adhesive. The core board 3 has the same shape, size and area as the skeleton panel 1.
[0035] (3) Production process of back plate 2: Back plate 2 is a plate with the same material, thickness and finish as bone panel 1. The specifications and size of back plate 2 are the same as bone panel 1 and core board 3.
[0036] 2. Fabrication of the skeleton cabinet door blank slab
[0037] The top surface of the core board 3 is glued to the skeleton panel 1, and the bottom surface is glued to the back plate 2. The glued board blanks are pressed with a press (cold press or hot press) and the adhesive is cured to obtain the skeleton cabinet door blank large board.
[0038] 3. Processing of raw large panels for cabinet doors
[0039] After the rough cabinet door panels are laid out, they are cut to length according to the specifications and dimensions of the cabinet doors using a computer-controlled cutting saw (each rough panel can be a cabinet door of one size or several cabinet doors of the same or different sizes). The cut cabinet door panels are edge-banded using a fully automatic or semi-automatic edge banding machine, then hinge holes are drilled, and they are stacked and sent to the balancing treatment room for treatment (to eliminate stress and prevent deformation).
[0040] 4. Molding
[0041] After balancing treatment, the solid wood frame cabinet door panels are painted, and can be painted in open, semi-transparent, fully enclosed, or single-color styles.
[0042] After being balanced, the paint-free cabinet door panels undergo quality inspection, packaging, and warehousing.
[0043] The pressed-molded frame cabinet door panel, produced using a new process technology, has its frame lines 6 formed as a single piece. The door core and frame lines 6 are an integral structure (without splicing gaps), eliminating the problem of cracking in the lines and door core. Furthermore, it can be mass-produced, with production costs more than 30% lower than similar products, and the quality is stable. It can produce both high-end solid wood painted frame cabinet door panels and engineered wood panel paint-free cabinet door panels.
[0044] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
