Problems solved by technology

In order to maintain the development of the plywood industry, on the one hand, a large number of logs and veneers are imported; There are many broken boards and broken boards. In the production of plywood, it takes a lot of man-hours to arrange and splice these veneers. At the same time, core stacking and core separation will occur during billet assembly, which seriously affects the quality and production efficiency of plywood.
[0004] For the above-mentioned problems, the industry has made efforts in various aspects, from improving the performance of processing equipment such as the use of advanced non-clamping shafts and small-diameter rotary cutters. Although the log output rate has been improved, the quality of veneers has not been fundamentally improved. Chinese patent CN17183874 discloses "artificial wood and its manufacturing method". In this method, a single plate is obtained by rotary cutting small-diameter logs, and then a whole continuous veneer is obtained by splicing, which is heated and rolled to form artificial wood, and then the artificial log is peeled. However, this method still has the problem of broken boards and many broken boards produced by using small-diameter logs to make veneers

Embodiment 1

[0041] Embodiment 1 Integrated wood structure

[0042] Such as figure 1 As shown, the integrated wood described in the application of the present invention, as a whole, is composed of a central cylindrical core 1 and a plurality of annular integrated wood monomers 2 sheathed outside the core 1, and the core 1 The two ends are closed, and the two ends of the core 1 are provided with positioning devices corresponding to the clamping head of the rotary cutting machine.

[0043] Such as figure 2 The core 1 is composed of a metal inner core 10 with closed ends at the center and a circular wood structure layer 11 close to the metal inner core 10; the inner and outer rings of each ring-shaped integrated wood monomer 2 It is a concentric ring, wherein the outer ring diameter of each integrated wood monomer 2 is the same, and the inner ring diameter is slightly larger than the diameter of the integrated wood core body 1. Preferably, the integrated wood monomer 2 and the core body 1 There ...

Embodiment 2

[0046] Example 2 Processing and production of integrated wood

[0047] The integrated wood described in the application of the present invention is manufactured by the following steps:

[0048] 1. The production of the core body: take a cylindrical metal core with closed ends, inlay or cement a layer of wood structure around the metal core;

[0049] 2. Board production: processing logs, short boards and low-quality logs into 1-8 cm thick boards with various thicknesses;

[0050] 3. Production of fan-shaped blanks: sizing and splicing multiple plates of equal thickness into a whole board, and then cut into fan-shaped blanks of integrated wood monomer, the central angle of each fan-shaped blank is between 5°-25° The inner and outer arcs of the fan-shaped blank are concentric arcs. The diameter of the outer arc is equal to the diameter of the integrated wood to be obtained. The diameter of the inner arc is slightly larger than the diameter of the core. The board edge of the board is ver...

Embodiment 3

[0057] Example 3 Utilization method of integrated wood

[0058] The application of the present invention also provides a method for using the integrated wood. When the rotary cutting machine is used to make veneer, the rotation direction of the integrated wood is clockwise rotation, that is, it moves in the direction of the direction identification arrow. The feed direction moves towards each other, and the processing ends when the rotary cutting process reaches the wood structure layer of the integrated wood core, and the integrated wood core can be reused.

[0059] In summary, the application of the present invention provides a method that can turn waste into treasure by combining short and small boards and low-quality wood through reasonable cutting and splicing to obtain large-diameter integrated wood, which can replace naturally-growing large-diameter logs. Processing into high-quality veneer with excellent strength improves and improves the quality and production efficiency o...

Abstract

The invention provides a method for producing a large-diameter glued laminated timber from logs with short and small diameter and low quality, an obtained glued laminated timber and a utilization method thereof. The glued laminated timber can be produced into wide-width and whole continuous veneers by rotary-cut. The produced glued laminated timber is formed by bonding a central columned core body and a plurality of single annular glued laminated timber sheets which are sleeved on the core body, wherein the core body consists of a metal inner core with enclosed two ends and a wood structure layer closely laminated to the metal inner core, each glued laminated timber sheet is formed by aligning, splicing and bonding a plurality of sector blank boards with equal thickness, each sector blank board is formed by splicing, gluing and cutting a plurality of flat jointed boards equal in thickness, the sides of the jointed boards are perpendicular to one sloping sides of the sector blank boards, therefore, the obtained glued laminated timber is directional, and the better rotary-cut effect along the fiber can be achieved in the rotary-cut process.

Description

Technical field [0001] The application of the present invention relates to an integrated wood and its manufacturing and utilization methods, especially a method for manufacturing large-diameter integrated wood using short, small boards and low-quality logs. The application of the present invention also relates to the integrated wood obtained by this method and its use . Background technique [0002] Plywood is a three-layer or multi-layer board-like material made of wood pieces that are peeled into veneer or sliced ​​into veneer from wood, and then glued with adhesive. Usually, odd-numbered veneers are used and adjacent layers of veneers are used. The fiber direction is perpendicular to each other and glued together. Plywood is produced with wood as the main raw material. Due to the rationality of its structure and the fine processing in the production process, the defects of wood can be largely overcome, and the physical and mechanical properties of wood can be greatly improved...
