Description

Technical Field

[0001] This utility model relates to the field of decorative panel edge folding technology, and in particular to a decorative panel raindrop-shaped filled rounded corner edge folding shape and its preset groove shape. Background Technology

[0002] Folding the edges of decorative panels to create an L-shaped effect is a common technique. This technique makes the transition surface seamless, resulting in an aesthetically pleasing appearance. However, the folded corners can only be right angles or bevels, leading to a sharper visual and tactile feel and a somewhat limited style. Using hot melt adhesive to create rounded corners, however, results in less support due to the liquid state of the adhesive when heated, leading to less rounded and imperfect corners.

[0003] Therefore, there is an urgent need for a decorative panel with rounded corners and smooth edges to enrich the visual and tactile design style of L-shaped edge decorative panels. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a decorative panel with a raindrop-shaped filled rounded corner folded edge shape and its preset groove shape.

[0005] This decorative panel features a raindrop-shaped filled rounded corner folded edge design and a pre-designed groove, comprising: a main board and a folded edge plate; the bottom of the main board and the folded edge plate is a decorative layer, and the top is a non-decorative side; a pre-designed groove is located between the non-decorative side of the main board and the non-decorative side of the folded edge plate, and the main board, the folded edge plate, and the pre-designed groove are an integral structure; the side wall contours of the main board and the side wall contours of the folded edge plate match; the pre-designed groove includes a right straight segment, an arc segment, and a left straight segment, with the left straight segment connected to the end of the main board and the right straight segment connected to the end of the folded edge plate.

[0006] Preferably, one end of the right straight segment is connected to and tangent to the arc segment to form a right tangent point, and the other end of the right straight segment is a right closure point; one end of the left straight segment is connected to and tangent to the arc segment to form a left tangent point, and the other end of the left straight segment is a left closure point; the point where the arc segment is closest to the finishing layer is the bottom point.

[0007] Preferably, the preset groove shape is a symmetrical structure, and its axis of symmetry is a perpendicular line passing through the bottom point of the arc segment.

[0008] Preferably, the right closing point and the left closing point coincide, the main board and the folded edge board are perpendicular, and the corners of the finishing layer are rounded.

[0009] Preferably, the space enclosed by the pre-set groove is a raindrop-shaped inner cavity, and the raindrop-shaped inner cavity is filled with hot melt adhesive. The space in the raindrop-shaped inner cavity other than the hot melt adhesive is an empty cavity.

[0010] Preferably, the mating surfaces of the sidewalls of the motherboard and the non-finished side of the folded edge plate are provided with initial fixing hot melt adhesive.

[0011] The beneficial effects of this utility model are:

[0012] 1) The folded edge of this utility model is formed into a raindrop-shaped inner cavity after bending and extrusion. The folded edges are initially bonded together with hot melt adhesive. The raindrop-shaped inner cavity is filled with hot melt adhesive, which is used to bond and fix the bending part a second time. The cavity inside the raindrop-shaped inner cavity is used to release air and avoid excessive adhesive, which would create resistance in the folding process and ensure that the main board and the folded edge board are perpendicular. Through the cooperation of hot melt adhesive and cavity, the main board and the folded edge board are perpendicular, ensuring the firmness of the rounded corner folded edge structure.

[0013] 2) The preset groove of this utility model is a symmetrical structure, which forms a symmetrical raindrop-shaped inner cavity when bent, which helps the main board and the folded edge plate to form a vertical structure and realize vertical assembly. Attached Figure Description

It should be noted that, for those skilled in the art, several modifications can be made to the present invention without departing from the principle of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.

[0021] As one embodiment, a raindrop-shaped filled rounded corner folded edge design for decorative panels and its preset groove shape are proposed, such as... Figure 1-5 As shown, it includes: a main board 103 and a folded edge plate 104; the bottom of the main board 103 and the folded edge plate 104 is a decorative layer 102, and the top is a non-decorative side; a preset groove 2 is formed between the non-decorative side of the main board 103 and the non-decorative side of the folded edge plate 104, and the main board 103, the folded edge plate 104 and the preset groove 2 are an integral structure; the side wall contour of the main board 103 matches the side wall contour of the folded edge plate 104; the preset groove 2 includes a right straight segment 202, an arc segment 204 and a left straight segment 209, the left straight segment 209 is connected to the end of the main board 103, and the right straight segment 202 is connected to the end of the folded edge plate 104. The right straight segment 202 is connected to the arc segment 204 at one end and is tangent to form a right tangent point 203, and the other end of the right straight segment 202 is a right closure point 201; the left straight segment 209 is connected to the arc segment 204 at one end and is tangent to form a left tangent point 208, and the other end of the left straight segment 209 is a left closure point 210; the point where the arc segment 204 is closest to the decorative layer 102 is the bottom point 205; there are transition points 1 206 and 207 between the bottom point 205 and the left tangent point 208; the arc segment 204 is a segment of a perfect circle, and its radius can control the size of the rounded corner 301 after folding;

[0022] like Figure 1 As shown, the decorative panel 1 includes a substrate 101 and a decorative layer 102. The substrate 101 is divided into a main board 103 and a folded edge board 104. The decorative layer 102 is located at the bottom of the substrate 101. The material of the substrate 101 of the decorative panel 1 is MDF or plywood, and the material of the decorative layer 102 is PVC, PP, PET, PETG or paper film.

[0023] like Figure 2 As shown, the preset groove type 2 is a symmetrical structure, and its axis of symmetry is the perpendicular line passing through the bottom point 205 of the arc segment 204. When bent, it forms a raindrop-shaped inner cavity 302 with a symmetrical structure, which helps the main board 103 and the folded edge plate 104 to form a vertical structure and realize vertical assembly.

[0024] like Figure 2 , 4As shown in Figure 5, the forming structure 3 formed by bending the main board 103 and the folding plate 104 includes a rounded corner 301, a raindrop-shaped inner cavity 302, a hot melt filling 303, a cavity 304, and an initial fixing hot melt adhesive 305; the right closing point 201 and the left closing point 210 coincide, the main board 103 and the folding plate 104 are perpendicular, and the turning point of the decorative layer 102 is a rounded corner 301; the space enclosed by the preset groove 2 is the raindrop-shaped inner cavity 302, the raindrop-shaped inner cavity 302 is filled with hot melt adhesive 303, and the space of the raindrop-shaped inner cavity 302 other than the hot melt filling 303 is the cavity 304; the groove sidewall of the main board 103 and the non-decorative side of the folding plate 104 are provided with initial fixing hot melt adhesive 305; the cavity 304 in the raindrop-shaped inner cavity 302 is used for venting and at the same time avoids excessive hot melt filling 303 from causing resistance to the folding process, ensuring that the main board 103 and the folding plate 104 are perpendicular.

[0025] This type of decorative panel features a raindrop-shaped filling with rounded corners and a pre-set groove bending method, such as... Figure 1-5 As shown, it includes the following steps:

[0026] Step 1: Use a milling cutter to cut a groove on the non-finished side of the decorative panel 1 to form a preset groove 2. At this time, a main board 103 and a folded edge plate 104 are formed on both sides of the preset groove 2.

[0027] Step 2: Inject hot melt adhesive 303 into the bottom of the preset groove 2, and inject initial fixing hot melt adhesive 305 into the non-finished side of the folded edge plate 104 near the preset groove 2.

[0028] Step 3: The main board 103 is fixed, and the folded edge plate 104 is folded upward under force. Under the same material and the same force, the thinner the thickness, the greater the strain. The thinnest point 205 of the preset groove 2 starts to bend and deform first. When the force gradually increases to a certain point, the transition point 206, which is thicker than the bottom point 205, follows the bending and deformation. The transition point 207 and countless points thereafter increase in sequence.

[0029] Step 4: The left closing point 201 and the right closing point 210 come into contact to complete the folding and form a raindrop-shaped inner cavity 302. At this time, the initial fixing hot melt adhesive 305 is used to bond the main board 103 and the folding plate 104, providing an initial fixing effect. The filling hot melt adhesive 303 is squeezed and deformed to form a raindrop shape. After curing, it continues to support the rounded corner 301 and completes the folding action. The volume of the filling hot melt adhesive 303 is controlled to be less than the volume of the raindrop-shaped inner cavity 302. After molding, a cavity 304 is formed, which helps to vent air and can avoid excessive adhesive from causing resistance in the folding process and ultimately causing the main board 103 and the folding plate 104 to be non-perpendicular.
