Abstract
Description
Technical Field
[0001] This utility model belongs to the field of edge banding technology, and in particular to an edge banding structure for furniture panels. Background Technology
[0002] Edge banding is mainly used for the protection and beautification of the edges of boards. It can prevent formaldehyde from volatilizing from inside the board and improve the moisture-proof, waterproof and fire-proof properties of furniture.
[0003] Current edge banding manufacturing methods combine three different edge banding materials or processes, making it difficult to effectively mimic the aesthetics of compact laminate on thin panels. This may limit design possibilities, and because the edge banding material is made of plastic, it is easily damaged by impact, abrasion, or high temperatures, potentially leading to cracking, splitting, or fading, affecting the furniture's appearance and lifespan. Furthermore, achieving a strong and lasting bond between the edge banding and the panel core material is very difficult, especially in environments with constantly changing temperature and humidity. Weak adhesion can cause the edge banding to detach, affecting both function and appearance. Moreover, all edge banding materials are generally quite hard and rigid, posing a safety hazard to users. Utility Model Content
[0004] In view of this, the present invention provides an edge banding structure for furniture panels that can increase durability and safety to meet industrial needs.
[0005] An edge banding structure for furniture panels includes a core board and at least one thermoplastic elastic edge banding strip disposed on the edge of the core board. The core board includes a core board body, at least one decorative layer disposed on one sidewall of the core board body, and at least one thermoplastic surface layer disposed on the sidewall of the core board body. Each thermoplastic surface layer corresponds to one of the thermoplastic elastic edge banding strips. The thermoplastic elastic edge banding strip further includes an edge banding strip body and a coloring layer disposed on one side of the edge banding strip body. At least one cut surface is provided on the outer edge of the edge banding strip body, and the coloring layer is the same color as the decorative layer. When the thermoplastic elastic edge banding strip is disposed on the core board, the thermoplastic surface layer corresponds to the thermoplastic elastic edge banding strip, so that the thermoplastic elastic edge banding strip and the core board are heat-pressed into a single unit.
[0006] Furthermore, the thermoplastic elastic edge banding strip is made of any one or more combinations of chlorinated polyethylene, thermoplastic elastomer, thermoplastic polyolefin, thermoplastic polyurethane, and thermoplastic vulcanized elastomer.
[0007] Furthermore, the thermoplastic elastic edge banding strip is entirely colored.
[0008] Furthermore, the thermoplastic elastic edge banding also includes a topcoat layer disposed on the cut surface and a protective layer disposed on the outer side wall of the edge banding body, wherein the depth of the cut surface is at least 50% of the thickness of the thermoplastic elastic edge banding.
[0009] Furthermore, the protective layer is made of any one of abrasive particles, antibacterial particles, or ultraviolet inhibitors.
[0010] Furthermore, the outer contour of the thermoplastic elastic edge banding strip is either semi-circular or circular.
[0011] Furthermore, the Shore hardness of the edge banding strip body is ≤50HD.
[0012] Furthermore, the surface of the decorative layer is provided with any one of the following: a thin film, a metal foil, a printed pattern, or a coating.
[0013] Compared with existing technologies, the edge banding structure for furniture panels provided by this utility model protects the core board by setting the thermoplastic elastic edge banding strip on the core board. The core board includes a core board body and two thermoplastic surface layers symmetrically arranged on the core board body. Each thermoplastic elastic edge banding strip includes an edge banding strip body and a thermoplastic area disposed on one side of the edge banding strip body. The thermoplastic elastic edge banding strip itself is elastic, thus protecting the core board. When the thermoplastic elastic edge banding strip is set on the core board, the thermoplastic surface layer and the thermoplastic area correspond to each other, so that the thermoplastic elastic edge banding strip and the core board are heat-pressed into a whole. It can be seen that the thermoplastic elastic edge banding strip in the edge banding structure for furniture panels is adhered to the core board through a heat-pressing bonding process, ensuring a strong and durable bond, thereby improving the furniture's resistance to damage and service life, preventing users from being injured by bumps, and enhancing the safety of the core board.

[0017] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.
[0018] like Figures 1 to 3 The diagram shows a structural schematic of the edge banding structure for furniture panels provided by this utility model. The edge banding structure for furniture panels includes a core board 10 and at least one thermoplastic elastic edge banding strip 20 disposed on one side of the core board 10. The edge banding structure for furniture panels also includes other functional modules, such as assembly components, etc., which are technologies known to those skilled in the art and will not be described in detail here.
[0019] like Figures 1 to 2 The diagram shown is a structural schematic of the first embodiment of the edge-sealing structure for furniture panels provided by this utility model. The core board 10 includes a core board body 11, at least one decorative layer 12 disposed on one side wall of the core board body, and at least one thermoplastic surface layer 13 disposed on the side wall of the core board body 11.
[0020] The core board body 11 is a type of board material used in home decoration and furniture manufacturing. The core board body 11 is a prior art and will not be described in detail here.
[0021] The decorative layer 12 is provided with any one of a thin film, metal foil, printed pattern or coating, so that the decorative layer 12 forms a decorative pattern on the surface. The decorative layer 12 is a prior art and will not be described in detail here.
[0022] The thermoplastic surface layer 13 is disposed on the outside of the core board body 11. Each thermoplastic surface layer 13 corresponds to a thermoplastic elastic edge banding strip 20, so that the thermoplastic elastic edge banding strip 20 can be fixed to the core board 10. The connection structure between the thermoplastic surface layer 13 and the core board body 11 is a prior art, which will not be described in detail here.
[0023] The thermoplastic elastic edge banding strip 20 also includes an edge banding strip body 21, at least one cut surface 22 with the outer edge of the edge banding strip body 21, a topcoat layer 23 on the surface of the cut surface 22, and a protective layer 24 on the outer wall of the edge banding strip body 21.
[0024] The outer contour of the edge banding strip body 21 is either semi-circular or circular. Each thermoplastic elastic edge banding strip 20 is made of any one or more of chlorinated polyethylene (CPE), thermoplastic elastomer (TPE), thermoplastic polyolefin (TPO), thermoplastic polyurethane (TPU), and thermoplastic vulcanizate (TPV). That is, the edge banding strip body 21 is made of thermoplastic elastic material, and the Shore hardness of the thermoplastic elastic edge banding strip 20 is ≤50HD, so that the thermoplastic elastic edge banding strip 20 can be hot-pressed together with the thermoplastic surface layer 13, and the edge banding strip body 21 has elasticity.
[0025] The thermoplastic elastic edge banding strip 20 is interconnected with the thermoplastic surface layer 13, thereby fixing the thermoplastic elastic edge banding strip 20 to the core board 10. During processing, the thermoplastic elastic edge banding strip 20 is adhered to the core board 10 through a hot-pressing bonding process, ensuring a strong and durable bond, thus improving the furniture's resistance to damage and its service life. The thermoplastic elastic edge banding strip 20 is also composed of thermoplastic plastic, ensuring material compatibility and promoting a strong bond through hot lamination, while also ensuring the waterproofness of the panel and assembled furniture.
[0026] In addition, the thermoplastic elastic edge banding strip 20 is colored throughout, that is, the thermoplastic elastic edge banding strip 20 adopts a uniform full-color penetration technology, so that the thermoplastic elastic edge banding strip 20 has a uniform color and a visually attractive aesthetic, which is particularly advantageous for imitating the appearance of compact laminate.
[0027] The cutting surface 22 is provided on the edge banding strip body 21. During the processing of the thermoplastic elastic edge banding strip 20, the operator cuts the edge banding strip body 21 according to design requirements to make the edge banding strip body 21 meet the design requirements. The cut surface of the edge banding strip body 21 is the cutting surface 22. In addition, since the thermoplastic elastic edge banding strip 20 is colored throughout, it creates a visual effect where part of the edge banding strip body 21 is exposed to reveal the overall color.
[0028] The topcoat layer 23 is a thin and transparent protective topcoat. The topcoat layer 23 is used to protect the cut surface 22. The topcoat layer 23 is a prior art and will not be described in detail here.
[0029] The protective layer 24 is made of any one of abrasive particles, antibacterial particles, and ultraviolet inhibitors. The protective layer 24 protects the edge banding strip body 21 and improves the wear resistance and impact resistance of the outer side of the edge banding strip body 21. The protective layer 24 is existing technology and will not be described in detail here.
[0030] like Figure 3 As shown, it is a structural schematic diagram of the second embodiment of the edge banding structure for furniture panels provided by this utility model.
[0031] The edge banding structure for furniture panels includes a core board 30 and three thermoplastic elastic edge banding strips 40 respectively disposed on three sides of the core board 30. Compared with the second embodiment, the core board 10 in the first embodiment has the same structure as the core board 30 in the second embodiment, and the thermoplastic elastic edge banding strip 20 in the first embodiment has the same structure as the thermoplastic elastic edge banding strip 40 in the second embodiment, which will not be described again here.
[0032] The only difference between the first embodiment and the second embodiment is that the second embodiment has three thermoplastic elastic edge banding strips 40, which are respectively set on the three sides of the core board 30 to cover the three side walls of the core board 30. This allows the edge banding structure used for furniture panels to protect the edges of the board from damage on all three sides, while also serving an aesthetic purpose.
[0033] Compared with the prior art, the edge banding structure for furniture panels provided by this utility model protects the core board 10 by setting the thermoplastic elastic edge banding strip 20 on the core board 10. The core board 10 includes a core board body 11 and two thermoplastic surface layers 13 symmetrically arranged on the core board body 11. Each thermoplastic elastic edge banding strip 20 includes an edge banding strip body 21 and a thermoplastic area 22 disposed on one side of the edge banding strip body 21. The thermoplastic elastic edge banding strip 20 itself is elastic, thus protecting the core board 10. When the thermoplastic elastic edge banding strip 20 is placed on the core board, the thermoplastic surface layer and the thermoplastic area correspond to each other, so that the thermoplastic elastic edge banding strip and the core board are hot-pressed into a whole. It can be seen that the thermoplastic elastic edge banding strip 20 in the edge banding structure used for furniture panels is attached to the core board 10 through a hot-pressing bonding process, ensuring a firm and durable bond, thereby improving the furniture's resistance to damage and service life, preventing users from being bumped and injured, and improving the safety of the core board 10.
[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
