Description

Technical Field

[0001] The utility model relates to the technical field of boards, in particular to a solid wood board core with strong anti-deformation ability. Background Art

[0002] The solid wood board core is made of complete wood. It is not only firm and durable, but also has natural and beautiful texture, and is a high-quality board for building decoration and furniture making. Affected by the changes in air temperature and humidity, the solid wood fibers will expand and contract thermally. Moreover, with the differences in positions inside and outside the solid wood board core, the fibers at different positions inside and outside the solid wood board core are affected differently, and the degree of thermal expansion and contraction is also different. 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 severe 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. The different degrees of thermal expansion and contraction of the solid wood fibers are likely to cause the solid wood board core to bend and deform. Moreover, 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 solid wood board core on the changes in air temperature and humidity 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. Content of the Utility Model

[0004] The purpose of the utility model is to provide a solid wood board core with strong anti-deformation ability.

[0005] The technical solution for realizing the purpose of the utility model is: a solid wood board core with strong anti-deformation ability, including a solid wood board core body. On the surface of the solid wood board core body, there is a first fracture line that breaks the solid wood fibers on the surface of the solid wood board core body. The depth of the first fracture line in the thickness direction of the solid wood board core body is D, the thickness of the solid wood board core body is L, and the relationship between D and L satisfies D < L. There is an included angle а between the first fracture line and the growth direction of the solid wood fibers of the solid wood board core body, and the size of the included angle а is 0 < а < 90°.

[0006] Furthermore, the first fracture line is a straight line or a wavy line; when the first fracture line is a wavy line, the angle а is formed by the center line of the first fracture line and the growth direction of the solid wood fiber of the solid wood board core body. When the first fracture line is a straight line, processing is more convenient. When the first fracture line is a wavy line, after the solid wood fiber on the surface of the solid wood board core body is formed into several small blocks by the first fracture line, each small block is mutually limited by the first fracture line, and the structural stability is better.

[0007] Furthermore, the first fracture lines are multiple, and the multiple first fracture lines are arranged in parallel and at intervals. The multiple first fracture lines can break the solid wood fibers on the surface of the solid wood board core body into multiple small pieces. The more small pieces there are, the smaller the size of the small pieces is, the less affected by deformation, and the stronger the deformation resistance is.

[0008] Furthermore, both ends of the first 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 first fracture line; on the other hand, the single first fracture line that penetrates the entire solid wood board core body is also easier to process.

[0009] Furthermore, the first fracture line is a cutting line or a line formed by carbonizing the solid wood fiber of the solid wood board core body. The first fracture line can be formed by cutting the surface of the solid wood board core body; or the first fracture line can be formed by carbonizing the surface of the solid wood board core body, such as laser carbonization. Compared with the cutting line, when the first fracture line is a line formed by carbonizing the solid wood fiber of the solid wood board core body, no filler is needed in the first fracture line, the solid wood board core body still has a smooth surface, the overall structure of the solid wood board core body is better, and processing is more convenient.

[0010] Furthermore, when the first fracture line is a cutting line, there is a filler in the first fracture line. After the filler is filled in the first fracture line, the flatness and internal sealing of the overall structure of the solid wood board core body are better.

[0011] Furthermore, the first fracture lines are provided on both surfaces of the solid wood board core body. The solid wood fibers on both surfaces of the solid wood board core body are formed into small blocks by the first fracture lines, and both surfaces of the solid wood board core body are less affected by deformation, and the solid wood board core body has stronger anti-deformation ability.

[0012] Furthermore, the first fracture lines on the two surfaces of the solid wood board core body are staggered. In the non-staggered distribution structure, since the first fracture 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 first fracture 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 first fracture 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.

[0013] Furthermore, the surface of the solid wood board core body is also provided with a second fracture line that breaks the solid wood fibers on the surface of the solid wood board core body, and the second fracture line forms a network line with the first fracture line. After the second fracture line is provided, the second fracture line and the first fracture line work together to form diamond-shaped small blocks of solid wood fibers on the surface of the solid wood board core body. Compared with the structure with only the first fracture line, the diamond-shaped small blocks are smaller in size and have stronger anti-deformation ability. At the same time, each diamond-shaped small block can form longitudinal and transverse limits with each other, and the stability of the solid wood board core body structure is better.

[0014] Furthermore, the second fracture lines are provided on both surfaces of the solid wood board core body, and the second fracture lines on the two surfaces of the solid wood board core body are staggered.

[0015] The utility model has a solid wood board core with strong deformation resistance. By arranging the first fracture line on the surface of the solid wood board core body, the solid wood fibers on the surface of the solid wood board core body can be broken into small pieces under the action of the first fracture line. The surface solid wood fibers of the solid wood board core body broken into small pieces are small in size and are affected by changes in air temperature and humidity and thermal expansion and contraction to a small extent. The deformation produced is greatly degraded, and can even be degraded to be invisible to the naked eye, close to no deformation, like a small piece of board, so that it is no longer a key factor affecting the quality of the solid wood board. In this way, the deformation resistance 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, in the solid wood board core with strong deformation resistance of the utility model, an angle а is formed between the first fracture line and the growth direction of the solid wood fiber of the solid wood board core body, and the size of the angle а is 0<а<90°, and the first fracture line is arranged obliquely relative to the growth direction of the solid wood fiber of the solid wood board core body. The inclined first fracture line has components in both the growth direction of the solid wood fiber of the solid wood board core body and in the direction perpendicular to the growth direction of the solid wood fiber, and the components in the two directions enable the solid wood fibers on the surface of the solid wood board core body to be broken not only in the growth direction of the solid wood fiber, but also in the direction perpendicular to the growth direction of the solid wood fiber. That is to say, the inclined first fracture line can simultaneously complete the fracture of the solid wood fibers on the surface of the solid wood board core body in two directions, and the solid wood board core body can prevent deformation in two directions. The overall deformation resistance of the solid wood board core body is better and the structural strength is stronger. Moreover, for the deformation resistance in two directions of the solid wood board core body, compared with setting longitudinal and transverse fracture lines corresponding to the two directions on the solid wood board core body, the solid wood board core of the utility model has strong deformation resistance, and the processing of a single group of the first fracture lines is more efficient and convenient.

[0022] The following is a detailed description of the preferred embodiment of the solid wood board core with strong anti-deformation ability of the utility model in conjunction with the accompanying drawings:

[0023] like Figures 1 to 4As shown in the figure, a solid wood board core with strong anti-deformation ability includes a solid wood board core body 1. On the surface of the solid wood board core body 1, there is a first fracture line 11 that causes the solid wood fibers on the surface of the solid wood board core body 1 to break. The depth of the first fracture line 11 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. There is an angle α between the first fracture line 11 and the growth direction of the solid wood fibers of the solid wood board core body 1, and the size of the angle α is 0 < α < 90°.

[0024] For the solid wood board core with strong anti-deformation ability of the present utility model, the first fracture line 11 is provided on the surface of the solid wood board core body 1. The depth of the first fracture line 11 in the thickness direction of the solid wood board core body 1 is less than the thickness of the solid wood board core body 1. 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 first fracture line 11, and the solid wood board core body 1 remains in a plate structure.

[0025] For the solid wood board core with strong anti-deformation ability of the present utility model, the setting of the first fracture line 11 is used to break the solid wood fibers on the surface of the solid wood board core body 1. Moreover, the size of the angle α between the first fracture line 11 and the growth direction of the solid wood fibers of the solid wood board core body 1 is 0 < α < 90°, and the first fracture line 11 is inclined with respect to the growth direction of the solid wood fibers of the solid wood board core body 1. The first fracture line 11 inclined with respect to the growth direction of the solid wood fibers of the solid wood board core body 1 has components in both the growth direction of the solid wood fibers of the solid wood board core body 1 and the vertical direction of this solid wood fiber growth direction. Among them, the component in the growth direction of the solid wood fibers causes the solid wood fibers on the surface of the solid wood board core body 1 to break along the grain in the growth direction of the solid wood fibers; the component in the vertical direction of the growth direction of the solid wood fibers causes the solid wood fibers on the surface of the solid wood board core body 1 to break transversely with respect to the growth direction of the solid wood fibers.

[0026] For the solid wood board core with strong anti-deformation ability of the present utility model, by setting the first fracture line 11 on the surface of the solid wood board core body 1, under the action of the first fracture line 11, the solid wood fibers on the surface of the solid wood board core body 1 can be broken into small pieces. The size of the solid wood fibers on the surface of the solid wood board core body 1 that are broken into small pieces is small, and the degree of thermal expansion and contraction due to the influence of air temperature and humidity changes is small. The generated deformation is greatly reduced, just like small pieces of wood board, and can even be reduced to the point where it is invisible to the naked eye, approaching no deformation, making it no longer the key factor affecting the quality of the solid wood board. In this way, the anti-deformation ability of the solid wood board core body 1 is greatly increased, the structure of the solid wood board core body 1 can be more stable, and the service life is extended.

[0027] In addition, in the solid wood board core with strong deformation resistance of the utility model, there is an angle а between the first fracture line 11 and the growth direction of the solid wood fiber of the solid wood board core body 1, and the size of the angle а is 0<а<90°, and the first fracture line 11 is inclined relative to the growth direction of the solid wood fiber of the solid wood board core body 1. The inclined first fracture line 11 has components in both the growth direction of the solid wood fiber of the solid wood board core body 1 and in the direction perpendicular to the growth direction of the solid wood fiber. The components in the two directions enable the solid wood fibers on the surface of the solid wood board core body 1 to be broken not only in the growth direction of the solid wood fiber, but also in the direction perpendicular to the growth direction of the solid wood fiber. That is to say, the inclined first fracture line 11 can simultaneously complete the fracture of the solid wood fibers on the surface of the solid wood board core body 1 in two directions, and the solid wood board core body 1 can prevent deformation in two directions. The solid wood board core body 1 has better overall deformation resistance and stronger structural strength. Moreover, with respect to the deformation resistance in two directions of the solid wood board core body 1, compared with setting longitudinal and transverse fracture lines corresponding to the two directions on the solid wood board core body 1, the solid wood board core of the utility model has strong deformation resistance, and the processing of a single group of the first fracture lines 11 is more efficient and convenient.

[0028] The utility model has a solid wood core with strong anti-deformation ability, wherein the first fracture line 11 can be a straight line, such as Figure 1~Figure 4 The first broken line 11 can also be a wavy line or a sawtooth line, such as Figure 5 As shown; when the first broken line 11 is a wavy line or a sawtooth line, the angle а is formed by the center line of the first broken line 11 and the growth direction of the solid wood fiber of the solid wood board core body 1.

[0029] The utility model has a solid wood board core with strong anti-deformation ability, and when the first broken line 11 is a straight line, processing is more convenient. When the first broken line 11 is a wavy line, after the solid wood fibers on the surface of the solid wood board core body 1 are formed into a plurality of small blocks by the first broken line 11, each small block is mutually limited under the action of the first broken line 11, and the structural stability is better.

[0030] In the utility model, the solid wood board core with strong anti-deformation ability is preferably provided with a plurality of first broken lines 11, and the plurality of first broken lines 11 are arranged in parallel and at intervals. The plurality of first broken lines 11 can break the solid wood fibers on the surface of the solid wood board core body 1 into a plurality of small pieces. The more small pieces there are, the smaller the size of the small pieces is, the less the deformation effect is, and the stronger the anti-deformation ability is.

[0031] In the utility model, the solid wood board core with strong deformation resistance is preferably provided with two ends of the first fracture line 11 penetrating the entire solid wood board core body 1. This arrangement, on the one hand, allows the solid wood fibers on the surface of the solid wood board core body 1 to be broken by the first fracture line 11; on the other hand, the single first fracture line 11 penetrating the entire solid wood board core body 1 is also easier to process.

[0032] In the utility model, the solid wood board core with strong anti-deformation ability is preferably formed by the first broken line 11 being a cutting line or a line formed by carbonizing the solid wood fiber of the solid wood board core body 1. The first broken line 11 can be formed by cutting the surface of the solid wood board core body 1; or the surface of the solid wood board core body 1 can be carbonized, such as by high-temperature burning of the solid wood fiber by laser, and the first broken line 11 is formed after the burned part is carbonized. Compared with the cutting line, when the first broken line 11 is a line formed by carbonizing the solid wood fiber of the solid wood board core body 1, there is no need to fill the first broken line 11 with fillers (not shown), and the solid wood board core body 1 still has a smooth surface, and the overall structure of the solid wood board core body 1 is better and more convenient to process.

[0033] The utility model has a solid wood core with strong anti-deformation ability. Preferably, when the first broken line 11 is a cutting line, there is a filler in the first broken line 11. After the filler is filled in the first broken line 11, the overall flatness and internal sealing of the solid wood core body 1 are better.

[0034] The utility model has a solid wood board core with strong deformation resistance, preferably, the first broken lines 11 are provided on both surfaces of the solid wood board core body 1. The solid wood fibers on both surfaces of the solid wood board core body 1 are formed into small blocks by the first broken lines 11, and the two surfaces of the solid wood board core body 1 are less affected by deformation, and the solid wood board core body 1 has stronger deformation resistance.

[0035] In the utility model, the solid wood board core with strong deformation resistance is preferably distributed in a staggered manner by the first broken lines 11 on the two surfaces of the solid wood board core body 1. In the non-staggered distribution structure, since the first broken lines 11 on the two surfaces of the solid wood board core body 1 are opposite, the middle connection thickness of the solid wood board core body 1 is small, and the structural firmness of the solid wood board core body 1 is poor. When the first broken lines 11 on the two surfaces of the solid wood board core body 1 are staggered, the solid wood fibers on the two surfaces of the solid wood board core body 1 can be formed into small blocks by the first broken lines 11, thereby improving the deformation resistance of the solid wood board core body 1, and the connection thickness of the solid wood board core body 1 is thicker, and the overall structural strength of the solid wood board core body 1 is stronger.

[0036] The utility model has a solid wood board core with strong anti-deformation ability. Preferably, the surface of the solid wood board core body 1 is also provided with a second broken line 12 that breaks the solid wood fibers on the surface of the solid wood board core body 1. The second broken line 12 forms a network line with the first broken line 11. After the second broken line 12 is provided, the second broken line 12 and the first broken line 11 work together to form diamond-shaped small blocks of solid wood fibers on the surface of the solid wood board core body 1. Compared with the structure with only the first broken line 11, the size of the diamond-shaped small blocks is smaller, and the anti-deformation ability is stronger. At the same time, each diamond-shaped small block can form a longitudinal and transverse limit with each other, and the stability of the structure of the solid wood board core body 1 is better.

[0037] The utility model has a solid wood board core with strong deformation resistance. Preferably, the second fracture lines 12 are provided on both surfaces of the solid wood board core body 1, and the second fracture lines 12 on the two surfaces of the solid wood board core body 1 are staggered.

[0038] The utility model has a solid wood board core with strong anti-deformation ability, and the second broken line 12 is the same as the first broken line 11, and the second broken line 12 can be a straight line or a wavy line. Both ends of the second broken line 12 can pass through the entire solid wood board core body 1. The second broken line 12 can be a cutting line, or a line formed by carbonizing the solid wood fiber of the solid wood board core body 1. When the second broken line 12 is a cutting line, the second broken line 12 has a filler.

[0039] The utility model has a solid wood board core with strong anti-deformation ability and has unlimited application fields, and is particularly suitable for the application of large-size boards, such as being particularly suitable for being the board core of door boards or cabinet boards.

[0040] For ordinary technicians in the technical field to which the utility model belongs, the utility model can make several simple deductions or substitutions without departing from the concept of the utility model, which should be regarded as falling within the protection scope of the utility model.
