Description

Technical Field

[0001] The utility model relates to the technical field of plates, in particular to a deformation-resistant solid wood board core that is simple and easy to process. Background Art

[0002] The solid wood board core is made of complete wood, which is not only firm and durable, but also has natural and beautiful grain, and is a high-quality plate for building decoration and furniture making. Affected by the changes in air temperature and humidity, the solid wood fibers will expand and contract thermally, and the degree of expansion and contraction of the fibers at different positions inside and outside the solid wood board core is also different due to the differences in positions inside and outside the solid wood board core. For example, the closer to the surface of the solid wood board core, the greater the influence of the solid wood fibers on the changes in air temperature and humidity, and the more serious the degree of thermal expansion and contraction; the closer to the center of the solid wood board core, the smaller the influence of the solid wood fibers on the changes in air temperature and humidity, and the smaller the degree of thermal expansion and contraction. Different degrees of thermal expansion and contraction of solid wood fibers are likely to cause the solid wood board core to bend and deform, and the larger the size of the solid wood board core, such as the length, the more obvious this kind of deformation is, and the greater the impact on the quality. Therefore, in the application of large-size solid wood board cores, such as in the production of solid wood doors, this kind of deformation has become one of the key factors affecting the quality of solid wood doors.

[0003] For the existing solid wood board cores, most of them reduce the influence of the changes in air temperature and humidity on the solid wood board core by painting, or resist deformation through the limitation of the connection structure. Although these methods can reduce and slow down the generation of deformation, they cannot completely avoid the deformation problem. After long-term use, the solid wood board core will still deform, and the quality will still be affected. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a deformation-resistant solid wood board core that is simple and easy to process.

[0005] The technical solution for realizing the purpose of the utility model is: a deformation-resistant solid wood board core that is simple and easy to process, including a solid wood board core body. On the surface of the solid wood board core body, there are fracture lines that break the solid wood fibers on the surface of the solid wood board core body. The depth of the fracture lines in the thickness direction of the solid wood board core body is D, and the thickness of the solid wood board core body is L. The relationship between D and L satisfies D < L. The fracture lines are formed by carbonizing the solid wood fibers of the solid wood board core body.

[0006] Further, the fracture lines are formed by carbonizing the solid wood fibers after laser high-temperature burning.

[0007] Further, the fracture lines are any one of straight lines, curves, wavy lines, and serrated lines.

[0008] Furthermore, there are a plurality of fracture lines, which can break the solid wood fibers on the surface of the solid wood board core body into a plurality of small pieces. The more small pieces there are, the smaller the size of the small pieces is, the less they are affected by deformation, and the stronger the deformation resistance is.

[0009] Furthermore, both ends of the fracture line penetrate the entire solid wood board core body. This arrangement, on the one hand, allows the solid wood fibers on the surface of the solid wood board core body to be broken by the fracture line; on the other hand, the single fracture line that penetrates the entire solid wood board core body is also easier to process.

[0010] Furthermore, the said broken lines are arranged on both surfaces of the said solid wood board core body. The said solid wood fibers on both surfaces of the said solid wood board core body are formed into small blocks by the said broken lines, and the said solid wood board core body is less affected by the deformation, and the said solid wood board core body has stronger anti-deformation ability.

[0011] Furthermore, the broken lines on the two surfaces of the solid wood board core body are staggered. In the non-staggered distribution structure, since the broken lines on the two surfaces of the solid wood board core body are opposite, the thickness of the middle connection of the solid wood board core body is small, and the structural firmness of the solid wood board core body is poor. When the broken lines on the two surfaces of the solid wood board core body are staggered, the solid wood fibers on the two surfaces of the solid wood board core body can be formed into small blocks by the broken lines, thereby improving the deformation resistance of the solid wood board core body, and the thickness of the connection of the solid wood board core body is thicker, and the overall structural strength of the solid wood board core body is stronger.

[0012] Furthermore, an angle а is formed between the fracture line and the growth direction of the solid wood fiber of the solid wood board core body, and the angle а is 0≤а≤90°. The fracture line can be arranged horizontally, longitudinally, or obliquely relative to the growth direction of the solid wood fiber of the solid wood board core body.

[0013] Furthermore, the fracture lines include transverse fracture lines, which are arranged transversely relative to the growth direction of the solid wood fibers of the solid wood board core body. The transverse fracture lines can cause the solid wood fibers on the surface of the solid wood board core body to fracture transversely.

[0014] Furthermore, the fracture lines include longitudinal fracture lines, which are arranged along the growth direction of the solid wood fibers of the solid wood board core body. The longitudinal fracture lines can cause the solid wood fibers on the surface of the solid wood board core body to fracture longitudinally.

[0015] The simply - processed anti - deformation solid wood board core of the utility model, by setting the fracture lines on the surface of the solid wood board core body, under the action of the fracture lines, the solid wood fibers on the surface of the solid wood board core body can be broken into small pieces. The size of the solid wood fibers on the surface of the solid wood board core body that is broken into small pieces is small, and the degree of thermal expansion and contraction under the influence of air temperature and humidity changes is small. The generated deformation is greatly reduced, just like small pieces of board, and can even be reduced to an invisible level to the naked eye, approaching no deformation, so that it is no longer the key factor affecting the quality of the solid wood board core. In this way, the anti - deformation ability of the solid wood board core body is greatly enhanced, the structure of the solid wood board core body can be more stable, and the service life is extended.

[0016] In addition, for the simply - processed anti - deformation solid wood board core of the utility model, the fracture lines are formed by carbonizing the solid wood fibers of the solid wood board core body. Compared with other lines that can break the solid wood fibers on the surface of the solid wood board core body, such as cutting lines, the lines formed by carbonizing the solid wood fibers of the solid wood board core body are easy to process. By controlling the temperature and path of the burning point, they can be quickly formed, and the formed lines have no grooves or seams, will not cause any damage or influence to the surface of the solid wood board core body, and do not require the filling operation of grooves or seams. Their formation is simple, the operation is easy, the processing is fast, and the efficiency is high. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will give a detailed description of the preferred embodiments of the simply - processed anti - deformation solid wood board core of the utility model with reference to the accompanying drawings:

[0021] As Figures 1 to 3 shown, a simply - processed anti - deformation solid wood board core includes a solid wood board core body 1. On the surface of the solid wood board core body 1, there are fracture lines 2 that break the solid wood fibers on the surface of the solid wood board core body 1. The depth of the fracture lines 2 in the thickness direction of the solid wood board core body 1 is D, and the thickness of the solid wood board core body 1 is L. The relationship between D and L satisfies D < L. The fracture lines 2 are formed by carbonizing the solid wood fibers of the solid wood board core body 1.

[0022] The utility model has a simple and easy-to-process deformation-resistant solid wood board core, wherein the fracture line 2 is arranged on the surface of the solid wood board core body 1, and the depth of the fracture line 2 along the thickness direction of the solid wood board core body 1 is less than the thickness of the solid wood board core body 1, and along the thickness direction of the solid wood board core body 1, the solid wood fibers of the solid wood board core body 1 are not completely broken due to the fracture line 2, and the solid wood board core body 1 is still a plate structure with strong structural strength.

[0023] The utility model provides a simple and easy-to-process deformation-resistant solid wood board core, wherein the setting of the fracture line 2 is used to fracture the solid wood fibers on the surface of the solid wood board core body 1, and the fracture line 2 is a line formed by carbonizing the solid wood fibers of the solid wood board core body 1. The formation of the fracture line 2 is specifically, by subjecting the solid wood board core body 1 to high-temperature carbonization treatment, such as high-temperature laser burning, so that the solid wood fibers of the solid wood board core body 1 are carbonized after laser high-temperature burning. During the carbonization process, by controlling the carbonization area and path, a carbonized line can be formed, and the carbonized line is the fracture line 2.

[0024] The utility model provides a simple and easy-to-process deformation-resistant solid wood board core. By arranging the fracture lines 2 on the surface of the solid wood board core body 1, the solid wood fibers on the surface of the solid wood board core body 1 can be broken into small pieces under the action of the fracture lines 2. The surface solid wood fibers of the solid wood board core body 1 broken into small pieces are small in size and are affected by changes in air temperature and humidity, and the degree of thermal expansion and contraction is small, so the deformation produced is greatly degraded, and like small pieces of board, it can even be degraded to be invisible to the naked eye, close to no deformation, so that it is no longer a key factor affecting the quality of the solid wood board core. In this way, the deformation resistance of the solid wood board core body 1 is greatly enhanced, the structure of the solid wood board core body 1 can be more stable, and the service life is extended.

[0025] In addition, the lines that break the solid wood fibers on the surface of the solid wood board core body can conventionally be cutting lines, and the formation of cutting lines will inevitably produce cutting grooves, that is, the cutting lines will cause damage and influence on the surface of the solid wood board core body. At the same time, the cutting grooves will also affect the sealing of the fibers inside the solid wood board core. In order to avoid the above problems, it is often necessary to fill the cutting lines, which is very cumbersome and has low processing efficiency. The utility model is simple and easy to process the anti-deformation solid wood board core, and the broken lines 2 are the lines formed by the carbonization treatment of the solid wood fiber of the solid wood board core body 1. Compared with other lines such as cutting lines that can break the solid wood fiber on the surface of the solid wood board core body 1, the lines formed by the carbonization treatment of the solid wood fiber of the solid wood board core body 1 are easy to process. By controlling the temperature and path of the burning point, they can be quickly formed, and the formed lines are groove-free and seamless, and will not cause any damage or influence on the surface of the solid wood board core body 1, let alone the filling operation of the grooves.
