Description
Technical Field
The invention belongs to a novel artificial board, and particularly relates to a thin strip type solid wood composite integrated material.
Technical Field
The number of the cylinder-shaped wood mandrels of the thin strips (with the diameter of 2-3 CM) for producing the veneers and the plywood is huge, and how to reasonably and fully utilize the wood mandrels for reproducing the artificial boards is a difficult problem which needs to be solved by the artificial board production enterprises, and the problems of reducing waste, increasing income and increasing the supply quantity of the artificial boards are solved.
Because the technology of reusing the thin cylindrical wood core shaft for manufacturing the high-end solid wood laminated wood is still immature, the wood core shaft is still mostly burnt or processed into wood chips for producing fiber boards, and only a small part of the wood core shaft is applied to producing the sweeping handle and the relatively low-end solid wood laminated wood with low strength and low toughness.
At present, when the wood core shaft is applied to the preparation of solid wood integrated materials, the traditional four-side planing equipment is mainly adopted to plane the wood core shaft with thin strips in a cylindrical shape into square specifications and small square materials with four-side lines for production and utilization, so that the kinetic energy, the mechanical abrasion and the raw material consumption are extremely large, the processing cost is high, and the defects of unstable performance, high manufacturing cost and the like of finished products exist.
Meanwhile, when the wood core shaft is used as a raw material to produce the traditional solid wood integrated material, the finished product has the following technical defects: (1) because the natural tension deficiency defect exists in the wood core of the wood core shaft, the synthesized finished product is extremely easy to crack at the wood core position, so that the product is damaged and scrapped; (2) because the traditional plane splicing method is adopted, the bonding area between the wood square materials is limited, the bonding strength is weaker, and the finished product is easy to crack, scatter strips and the like.
In addition, when the thin cylindrical wood core shaft is used as a raw material and is produced by adopting a traditional integrated wood production process, the thin cylindrical wood core shaft is limited by the diameter of the wood core shaft, and only plates with limited thickness can be produced according to the diameter level of the wood core shaft, so that the requirements of the market on the thickness of various plates cannot be met.
Moreover, most of the constituent materials of the laminated wood are single wood. The single wood is easy to generate deformation, dry crack, distortion and other defects in the environment with large temperature and humidity changes. Which in turn affects the quality of the integrated material.

The composite board II (2) is formed by processing a composite board IV (7), and the composite board IV (7) consists of a plurality of square strips II (8) with four corners and two square strips 9 with two corners and circular edges; wherein, four corners circular arc edge small square strip two (8) are provided with four plane two (10), four corners cambered surface two (11), two corners circular arc edge small square strip (9) are provided with four plane three (12), two corners cambered surface (13), with above-mentioned a plurality of four corners circular arc edge small square strip two (8) and two corners circular arc edge small square strip (9) splice, during the concatenation, and two corners circular arc edge small square strip (9) are settled respectively in the left and right sides of a plurality of four corners circular arc edge small square strip two (8) assembly, form composite slab four (7) from this.
When the first composite board (1) and the second composite board (2) are combined into an integrated material, the first composite board (1) and the second composite board (2) are sequentially combined and spliced into a thin strip type solid wood composite integrated material according to the thickness requirement.
The invention has the following advantages:
1. the invention has novel structure composition, scientific and reasonable design.
2. In the invention, the four-corner arc edge-falling small square strips I (4) and the four-corner arc edge-falling small square strips II (9) which are combined to form the composite board I (1) and the composite board II (2) are realized by directly adopting a thin strip (diameter of 2-3 CM) cylindrical wood mandrel to plane out four planes of very few parts through low-power simple four-side planing; the two-angle arc edge-falling small square strip (9) is also realized by directly adopting a four-angle arc edge-falling small square strip I (4) or a four-angle arc edge-falling small square strip II (8) which is longitudinally divided into two parts; the method has the advantages of simple processing, low energy consumption and high wood utilization rate.
3. In the invention, the connecting surfaces of the first composite board (1) and the second composite board (2) are wavy cambered surfaces, so that the splicing and bonding areas of the two boards are larger and the bonding of the boards is firmer when the two boards are synthesized.
4. In the invention, after the first composite board (1) and the second composite board (2) are combined and spliced, the original splicing points of the first composite board (1) and the second composite board (2) are bonded in a staggered manner, and the strength of the board is improved.
5. In the invention, the formed thin-strip type solid wood composite integrated material not only has the physical characteristics of natural solid wood, but also overcomes the defects of the natural wood, and is scientific, reasonable, novel and unique. The method comprises the following steps: (1) The physical properties of natural wood are reserved, the air pipe fiber structure of the wood is not damaged, and the wood has a series of physical properties of the wood, such as indoor humidity adjustment, ultraviolet resistance and the like, of log materials; (2) The single wood has the defects of easy swelling, deformation, dry cracking, twisting and the like in the environment with large temperature and humidity changes, and particularly, the single wood has more outstanding performance than the single wood with larger size. The arc edge falling square strips prepared by the raw material fine strip cylindrical wood mandrel are tiny, the stress and the expansion coefficient of the square strips are correspondingly reduced, and when two plates are synthesized, the splicing and bonding area is larger, the anastomosis of the plates is firmer, and the formed integrated plate is correspondingly stable and firm, so that the defects of the single wood are overcome.
6. The invention fully utilizes the wood processing residues for secondary reproduction and cyclic utilization, and reduces environmental pollution caused by waste wood residues. Meanwhile, the market supply of the solid wood integrated materials is increased, the contradiction between supply and demand is eased, the timber harvest is reduced, and the income of enterprises is increased.
