Description

Technical Field

[0001] This utility model relates to the field of home decoration technology, specifically to a multi-layer, multi-color edge banding strip. Background Technology

[0002] In furniture manufacturing, decoration and renovation and other fields, polymer boards (such as particleboard, fiberboard, etc.) are widely used because of their low cost and good processability. However, the cross-section of polymer boards (the edge formed after cutting or processing) has problems such as easy wear, easy moisture absorption and poor aesthetics, which need to be solved by edge banding.

[0003] The existing edge banding technology has the following main shortcomings:

[0004] Insufficient connection stability: Traditional edge banding strips are mostly fixed by a single adhesive method, which is prone to falling off due to hot melt adhesive aging or external impact after long-term use; the connection interfaces of some detachable edge banding structures (such as buckles and card seats) have poor compatibility and are prone to loosening or jamming.

[0005] Inadequate sealing performance: The gap between the edge sealing strip and the cross-section of the polymer board can easily become a channel for moisture and dust to enter, causing the polymer board to swell due to moisture, damage to the internal structure, and affecting its service life.

[0006] Limited aesthetics and functionality: The color of the edge banding strip differs significantly from that of the polymer board, resulting in poor visual harmony; its functions are limited to basic protection, lacking extended functions such as nighttime warnings and decorations, making it difficult to meet the needs of diverse scenarios (such as anti-collision for children's room furniture, nighttime lighting assistance, etc.).

[0007] Low maintenance convenience: The edge banding strip and the board are mostly non-detachable. If there is local damage (such as surface wear or functional component failure), the whole thing needs to be replaced, which increases maintenance costs.

[0008] Therefore, there is an urgent need for a multi-layered, multi-color integrated, and securely connected edge banding strip to address the shortcomings of existing structural technologies. Utility Model Content

[0009] To address the aforementioned technical problems, this utility model provides a multi-layer, multi-color edge banding strip to solve the issues raised in the background section.

[0010] The material includes a polymer board, the front end of which is coated with a cross section, and the front end of the cross section is fixedly connected to a first edge sealing strip, and the front end of the first edge sealing strip is connected to a second edge sealing strip.

[0011] The first edge sealing strip includes an adhesive surface, a primary color layer, and a mounting base. The adhesive surface is bonded to the front end of the cross section, the primary color layer is bonded to the front end of the adhesive surface, and the mounting base is fixedly connected to the front end of the primary color layer.

[0012] The rear end of the second edge sealing strip is fixedly connected with a buckle, which is slidably sleeved inside the card seat. Multiple sets of partition layers are fixed at equal intervals at the rear end of the second edge sealing strip, and multiple sets of 3D printed fluorescent strips are connected to the front end of the second edge sealing strip.

[0013] Preferably, the upper and lower edges of the adhesive surface are integrally formed with arc-shaped closures, the arc-shaped closures are fitted onto the outside of the cross-section, the outside of the adhesive surface is coated with hot melt adhesive, and a removable frosted protective film is pasted on the outside of the hot melt adhesive.

[0014] Preferably, the color of the primary color layer is the same as the color of the polymer plate.

[0015] Preferably, the card holder protrudes from the surface of the original color layer, and the card holder has a C-shaped groove structure.

[0016] Preferably, the buckle is a cylindrical protrusion that fits into the C-shaped groove.

[0017] Preferably, the spacing between two adjacent sets of the separator layers is 5-10 mm, and the separator layer is made of PC material.

[0018] Preferably, multiple sets of mounting grooves are symmetrically formed at both the upper and lower ends of the front end of the second edge sealing strip. The width of the mounting groove is between two adjacent sets of the partition layers. The 3D printed fluorescent strip is pasted into the interior of the mounting groove by reactive hot melt adhesive. The 3D printed fluorescent strip is made of fluorescent material.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. Improve connection stability and durability

[0021] The first edge sealing strip is double-fixed by hot melt adhesive on the bonding surface and arc edge sealing, which not only ensures tight bonding with the cross section of the polymer board, but also enhances the edge wrapping by arc edge sealing and reduces the risk of falling off;

[0022] The first and second edge sealing strips use a sliding fit of C-shaped brackets and columnar buckles, which has high interface compatibility, a firm connection that is not easy to loosen, and is easy to install and disassemble, reducing maintenance difficulty.

[0023] 2. Enhanced sealing and protective performance

[0024] The curved edge of the bonding surface is fitted onto the outside of the cross-section to form a ring-shaped sealing structure, which effectively prevents moisture and dust from penetrating into the interior of the polymer board, thus avoiding the board from getting damp, moldy, or structurally damaged.

[0025] The PC material separator layer of the second edge banding strip is both tough and impact-resistant, which can buffer the damage to the edge banding structure caused by external friction or collision and extend the overall service life.

[0026] 3. Optimize visual harmony and functional expandability

[0027] The original color layer of the first edge banding is consistent with the color of the polymer board, reducing the visual disjointedness caused by color difference and improving the overall aesthetics;

[0028] The 3D-printed fluorescent strip at the front end of the second edge banding uses fluorescent material, which can emit fluorescence in low-light environments to achieve extended functions such as nighttime warning (such as preventing children or the elderly from bumping into furniture edges) and decoration in low-light environments, adapting to diverse scenario needs; the 3D printing process can also flexibly adapt to the shape of the mounting groove to ensure the fit between the fluorescent strip and the edge banding.

[0029] 4. Improve maintenance convenience and cost controllability

[0030] The second edge sealing strip is designed to be detachable by sliding connection between the buckle and the card seat. If the 3D printed fluorescent strip is damaged or needs to be changed, the second edge sealing strip can be removed separately for maintenance without replacing the entire edge sealing structure.

[0031] The frosted protective film on the outer side of the adhesive surface can protect the hot melt adhesive before installation, prevent impurities from contaminating it, ensure the bonding effect, and reduce the installation loss rate. Attached Figure Description

[0038] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0039] Please see Figure 1-4 In this embodiment, a multi-layer multi-color edge banding strip is provided, including a polymer board 1, which serves as the basic carrier of the overall structure, provides main support, is the installation base for other components, and undertakes the main structural strength function.

[0040] The front end of the polymer board 1 is coated with a cross section 11, which is the treated surface of the front end of the polymer board. The coating process forms a flat interface that is compatible with the edge banding strip connection, which facilitates the stable bonding of the first edge banding strip and reduces wear or impurity intrusion on the cross section of the polymer board.

[0041] The front end of the cross section 11 is fixedly connected to a first edge sealing strip 2, and the front end of the first edge sealing strip 2 is connected to a second edge sealing strip 3;

[0042] The first edge sealing strip 2 includes an adhesive surface 21, a primary color layer 22, and a mounting base 23. The adhesive surface 21 is bonded to the front end of the cross-section 11, the primary color layer 22 is bonded to the front end of the adhesive surface 21, and the mounting base 23 is fixedly connected to the front end of the primary color layer 22. The upper and lower edges of the adhesive surface 21 are integrally formed with arc-shaped closures, which are fitted onto the outside of the cross-section 11. The outside of the adhesive surface 21 is coated with hot melt adhesive, and a removable frosted protective film is pasted on the outside of the hot melt adhesive. The color of the primary color layer 22 is the same as the color of the polymer board 1. The mounting base 23 protrudes from the surface of the primary color layer 22 and has a C-shaped groove structure.

[0043] The first edge sealing strip 2 is the intermediate structure connecting the polymer board and the second edge sealing strip, and it has the functions of fixing, sealing and aesthetics. The specific functions of the sub-components are as follows:

[0044] The adhesive surface 21 is fixed to the section 11 with hot melt adhesive to achieve mechanical connection; the arc edge of the upper and lower edges is fitted on the outside of the section to enhance the sealing performance and prevent moisture and dust from entering; the frosted protective sticker on the outside protects the hot melt adhesive before installation to prevent impurities from adhering in advance.

[0045] The original color layer 22 matches the color of the polymer board, which enhances the overall aesthetics through visual uniformity and reduces the color difference between the edge banding and the board.

[0046] The 23C-shaped groove structure of the card holder serves as the connection interface for the second edge sealing strip. Through cooperation with the buckle 31, it enables the second edge sealing strip to be detached / slidably fixed, while restricting the displacement direction of the second edge sealing strip.

[0047] The rear end of the second edge sealing strip 3 is fixedly connected to a buckle 31, which is slidably sleeved inside the card holder 23. Multiple sets of partition layers 32 are fixed at equal intervals at the rear end of the second edge sealing strip 3. Multiple sets of 3D printed fluorescent strips 33 are connected to the front end of the second edge sealing strip 3. The buckle 31 is a cylindrical protrusion adapted to the C-shaped groove. The spacing between two adjacent sets of partition layers 32 is 5-10mm. The partition layers 32 are made of PC material. Multiple sets of mounting grooves are symmetrically opened at the upper and lower ends of the front end of the second edge sealing strip 3. The width of the mounting groove is between two adjacent sets of partition layers 32. The 3D printed fluorescent strips 33 are pasted into the inside of the mounting groove by reactive hot melt adhesive. The 3D printed fluorescent strips 33 are made of fluorescent material.

[0048] The second edge banding strip 3 is located at the front end of the structure and serves to expand functionality and protect the structure. Its specific sub-component functions are as follows:

[0049] The cylindrical protrusions of the buckle 31 and the card seat 23 are adapted to achieve mechanical connection between the second edge sealing strip and the first edge sealing strip by sliding into the C-shaped groove, which facilitates installation, disassembly and maintenance;

[0050] The partition layer 32 is a PC material with equidistant raised structures spaced 5-10mm apart. On the one hand, it enhances the structural strength of the second edge sealing strip. PC material has good toughness and impact resistance. On the other hand, it can isolate the impact of external friction or collision on the internal structure, and at the same time provide a positioning reference for the front mounting groove.

[0051] The 3D-printed fluorescent strip 33 uses fluorescent materials and is fixed in the mounting groove with reactive hot melt adhesive. It can emit fluorescence in low light environments to achieve nighttime warning functions such as preventing collisions on furniture edges or decorative functions. The 3D printing process can adapt to complex mounting groove shapes to improve fit.

[0052] The present technology will be further explained below with reference to specific embodiments:

[0053] 1. Component pretreatment

[0054] The front end of the polymer board 1 is cut or ground to form a cross section 11, and then treated with coating processes such as smoothing and moisture-proofing to ensure that the surface is flat and suitable for bonding.

[0055] The outer side of the adhesive surface 21 of the first edge sealing strip 2 is pre-coated with hot melt adhesive and covered with a frosted protective film to prevent the hot melt adhesive from sticking to impurities during transportation or storage; the original color layer 22 has been pre-bonded to the adhesive surface 21 to ensure that the color is consistent with the polymer board.

[0056] The buckle 31 of the second edge sealing strip 3 and the partition layer 32 are fixedly formed. The spacing between the partition layers is preset to 5-10mm. The front mounting groove is opened according to the spacing between the partition layers to ensure that the installation position of the 3D printed fluorescent strip 33 is matched.

[0057] 2. Connection between the first edge banding strip and the polymer board

[0058] Remove the frosted protective film on the outside of the adhesive surface 21 of the first sealing strip 2 to expose the hot melt adhesive; activate the hot melt adhesive by heating or use the adhesiveness of the hot melt adhesive at room temperature, align the adhesive surface 21 with the cross section 11 of the polymer board, and apply pressure to make the two adhere tightly.

[0059] The arc edges of the upper and lower edges of the adhesive surface 21 naturally fit over the outside of the cross section 11, forming a sealed structure to prevent moisture and dust from entering the interior of the polymer board from the edge gaps; after the hot melt adhesive has cured, the first edge sealing strip 2 is firmly connected to the polymer board 1, and the original color layer 22 maintains visual uniformity with the polymer board.

[0060] 3. Connection between the second edge banding strip and the first edge banding strip

[0061] Align the buckle 31 at the rear end of the second edge sealing strip 3 with the C-shaped groove of the card seat 23 at the front end of the first edge sealing strip 2, and slide it along the length of the card seat so that the buckle 31 is completely inserted into the card seat 23.

[0062] At this time, the mechanical cooperation between the buckle 31 and the card seat 23 restricts the lateral displacement of the second edge sealing strip 3, ensuring a stable connection; the partition layer 32 at the rear end of the second edge sealing strip 3 contacts the original color layer 22 of the first edge sealing strip 2, and the toughness of the PC material buffers the possible external impact, while the spacing of the partition layer 5-10mm provides a spatial reference for the installation of the front fluorescent strip.

[0063] 4. Installation and Function Implementation of 3D Printed Fluorescent Strips

[0064] The 3D printed fluorescent strip 33 is attached to the mounting groove at the front end of the second edge sealing strip 3 using reactive hot melt adhesive. The width of the mounting groove matches the spacing of the separator layers to ensure accurate positioning of the fluorescent strip. After the reactive hot melt adhesive cures, the fluorescent strip is tightly connected to the second edge sealing strip and is not easy to fall off.

[0065] In daily use, the 3D printed fluorescent strip 33 absorbs ambient light such as natural light and artificial light, and releases fluorescence in low-light environments such as at night, achieving the following functions: if used on furniture such as cabinets and tabletop edges, it can warn users to avoid collisions; if used in decorative scenes, it can enhance the visual effect.

[0066] 5. Maintenance and Replacement

[0067] If you need to replace the 3D printed fluorescent strip 33, you can peel off the reactive hot melt adhesive, remove the old strip, and then re-attach the new strip.

[0068] If the second edge sealing strip 3 needs to be replaced, slide it in the opposite direction along the length of the card holder 23 to disengage the buckle 31 from the card holder 23, and the second edge sealing strip can be removed. Repeat step 3 after replacement.
