Description

Technical Field

[0001] The invention relates to the technical field of skirting boards, and in particular to a skirting board and a preparation method thereof. Background Art

[0002] Skirting lines are decorative lines specially set at the corners of indoor walls. They can effectively prevent damage from kicking and dirt from cleaning.

[0003] like Figure 1 As shown, in the existing interior decoration design process, an expansion joint F of about 10-15 mm is left between the floor B and the wall A. At the same time, the floor cannot be closely fitted with the wall during actual laying, so that a gap between the wall and the floor is inevitable. Therefore, a traditional skirting line T0 is needed to cover the gap. The skirting line needs to cover the top of the floor during installation, so the thickness of the traditional skirting line needs to be set slightly thicker than the gap to ensure that the gap is completely covered. This results in more skirting line consumables and a larger weight.

[0004] like Figure 2 As shown, in order to reduce the consumables and self-weight of the skirting board, the improved skirting board T1 can be set to a structure in which the upper wing plate and the lower support plate are connected by an obtuse angle, and the inner side of the upper wing plate abuts against the wall, and the bottom surface of the lower support plate abuts against the floor, so that the overall thickness of the skirting board can be reduced by 1 / 3 to 1 / 2, thereby reducing the consumables and self-weight of the skirting board.

[0005] However, in the process of preparing skirting boards, it is often necessary to apply glue between the upper wing plate and the lower support plate of the skirting board so that the upper wing plate and the lower support plate can be bent into a shape and size that matches the wall corner and the edge of the floor. For the upper wing plate and the lower support plate formed as one piece, the fixed structure is difficult to bend into shape, and there is a lack of space for applying glue, which further increases the difficulty of bending the skirting board blank plate. For the upper wing plate and the lower support plate of the split structure, the amount of glue applied is difficult to control. Applying too much glue will cause glue to overflow, affecting the bonding effect and polluting the surrounding environment. Applying too little glue will affect the bonding effect. At the same time, the connection strength and firmness of the skirting board with a split structure are insufficient.

[0006] Therefore, it is urgent to provide a new solution to solve the defects and shortcomings in the above-mentioned prior art. Summary of the invention

[0007] In order to solve the defects and shortcomings in the prior art, the present invention provides a mold and a control method thereof.

[0015] As a further preferred embodiment of the present invention, the angles on both sides of the filling groove are set to be equal angles or unequal angles.

[0016] As a further preferred embodiment of the present invention, along the thickness extension direction of the skirting board, the extension dimension of the connecting portion is smaller than the extension dimension of the filling groove.

[0017] As a further preferred embodiment of the present invention, along the thickness extension direction of the skirting board, the extension dimension of the connecting portion is set to 0.1-1 mm.

[0018] Furthermore, the present invention also provides a method for preparing a skirting board, which is characterized by comprising the following steps:

[0019] S1: Drying the raw material board for preparing the skirting board so that its humidity meets the preset requirements;

[0020] S2: sending the blank plate into the shaping device to shape the shape of the blank plate so that the shape and size of the blank plate after shaping meet the preset requirements;

[0024] S6: Sand the outside of the skirting, the outside of the filling groove and the outside of the connection.

[0025] The beneficial effects achieved by the present invention compared with the prior art include:

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0041] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] [First embodiment]

[0043] like Figure 3-5 The figure shows a skirting provided by the first embodiment of the present invention, comprising an upper wing plate 1 and a lower support plate 2 which are connected to each other and formed as one body, the upper wing plate 1 and the lower support plate 2 are arranged at an obtuse angle, the inner side of the upper wing plate 1 abuts against the wall, and the bottom surface of the lower support plate 2 abuts against the floor. The obtuse angle relationship between the upper wing plate 1 and the lower support plate 2 can be set accordingly according to the actual gap value between the edge of the floor and the wall, so that the gap can be completely covered.

[0044] The improvement of this embodiment compared with the prior art is that a filling groove 3 for accommodating glue is formed at the connection position between the upper wing plate 1 and the lower support plate 2, and the filling groove 3 gradually extends from the outside to the inside and does not penetrate the skirting board. The upper wing plate 1 and the lower support plate 2 are fixedly connected by a connecting portion 4, and the connecting portion 4 is arranged on the side of the opening portion 33 away from the filling groove 3, so that the filling groove 3 is convenient for the subsequent bending and forming of the skirting board as a whole, and the connection portion 4 is used to ensure the stability and firmness of the fixed connection strength between the upper wing plate 1 and the lower support plate 2. At the same time, the filling groove 3 can provide a glue accommodating space. By filling the filling groove 3 with glue, the amount of glue can be effectively controlled to avoid the problem of unstable connection strength and insufficient firmness caused by insufficient glue. The glue pressing process in the subsequent folding process can also press out excess glue, thereby further avoiding the influence of overflow glue on the bonding effect and the pollution of the surrounding environment.

[0045] In this embodiment, the cross-sectional shape of the filling groove 3 can be set to a corresponding V-shape, U-shape or teardrop shape according to the glue coating requirements, so as to meet the corresponding requirements of different glue coating amounts; wherein the V-shape is conducive to the glue flowing down along the inner wall of the filling groove 3 and converging at the bottom 32 of the filling groove 3, such as Figure 7 As shown; the U-shape is conducive to the glue filling the inner wall of the groove 3 when it is fully and evenly contacted with the inner wall of the filling groove 3, thereby providing the subsequent adhesive effect firmness and stability, such as Figure 8 The water drop shape is conducive to storing the glue inside the filling groove 3, minimizing the possibility of unexpected glue overflow, such as Figure 6 shown.

[0046] Preferably, the side wall 31 of the filling groove 3 can be set to a corresponding straight line or curve according to the glue coating requirements. Setting the side wall 31 to a straight line can facilitate the glue to flow downward into the filling groove 3. Figure 6 As shown; and setting the side wall 31 to a curved shape can increase the internal space of the filling slot 3 to increase the glue storage capacity, while also ensuring the stability of the glue staying inside the filling slot 3, avoiding the unexpected discharge of the glue inside the filling slot 3 during the subsequent glue pressing process, such as Fig. 9 shown.

[0047] In order to ensure that the glue is stably stored in the filling tank 3 and that the glue can fully and evenly contact the inner wall of the filling tank 3, the bottom 32 of the filling tank 3 is set to be an arc shape, such as Figure 6 shown.

[0048] In this embodiment, the opening 33 of the filling groove 3 is formed into a rounded corner after grinding, which not only facilitates the glue to enter the filling groove 3, but also minimizes the possibility of collision and damage between the upper wing plate 1 and the lower support plate 2 during the subsequent bending process.

[0049] As a further preference, Figure 6 As shown, the two sides 3A and 3B of the filling groove 3 are set to an axisymmetric or asymmetric shape; and the angles ∠1 and ∠2 on both sides of the filling groove 3 are set to equal angles or unequal angles, so that different corresponding symmetrical structures and angles can be set for the filling groove 3 according to the overall structural shape of the skirting board and the relative position and angle between the upper wing plate 1 and the lower support plate 2.

[0050] like Figure 5 As shown, in the present embodiment, along the thickness extension direction of the skirting line, the extension dimension of the connecting portion 4 is smaller than the extension dimension of the filling slot 3; and it is specifically set as follows: along the thickness extension direction of the skirting line, the extension dimension of the connecting portion 4 is set to 0.1-1mm, so that the stability and firmness of the fixed connection strength between the upper wing plate 1 and the lower support plate 2 are ensured by setting the connecting portion 4, and the bending and cracking caused by the connecting portion 4 being too thick and the increased requirements for the bonding strength of the glue can be avoided by setting the connecting portion 4 to a suitable thickness, and at the same time, the grinding through of the blank plate caused by the later grinding due to the connecting portion 4 being too thin can be avoided.

[0051] [Second embodiment]

[0052] The second embodiment of the present invention also provides a method for preparing a skirting board mentioned in the first embodiment, comprising the following steps:

[0053] S1: Drying the raw material board for preparing the skirting board so that its humidity meets the preset requirements;

[0054] S2: sending the blank plate into the shaping device to shape the shape of the blank plate so that the shape and size of the blank plate after shaping meet the preset requirements;

[0055] S3: slotting between the upper wing plate 1 and the lower support plate 2 of the blank plate after shaping, and making the size of the filling slot 3 meet the preset requirements;

[0056] S4: Apply glue to the inside of the filling slot 3 until the glue completely fills the inside of the filling slot 3;

[0057] S5: heating the glue-coated skirting board, folding the skirting board after it softens, and pressing out the excess glue coated on the opening 33 of the filling slot 3;
