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 one integrated wood structure

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

[0043] Such as figure 2 , the core body 1 is composed of a metal inner core 10 closed at both ends in the center and a circular wooden structure layer 11 close to the metal inner core 10; the inner and outer rings of each annular integrated wooden unit 2 It is a concentric ring, wherein the diameter of the outer ring of each integrated wood monomer 2 is equal, and the diameter of the inner ring is slightly larger than the diameter of the integrated wood core 1. Preferably, the distance between t...

Embodiment 2

[0046] Embodiment 2 The processing and manufacture of integrated wood

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

[0048] 1. The production of the core body: take a metal inner core with closed columns at both ends, and inlay or glue a layer of wood structure around the metal inner core;

[0049] 2. Production of boards: process logs, short boards, and low-quality logs into trimmed boards of various thicknesses with a thickness of 1-8 cm;

[0050] 3. Production of fan-shaped blanks: multiple panels of equal thickness are glued together to form a whole board, and then cut to form fan-shaped blanks with integrated wood monomers. 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 th...

Embodiment 3

[0058] Embodiment 3 Utilization method of integrated wood

[0059] The application of the present invention also provides the utilization method of the integrated wood. When using a rotary cutter to make veneers, the rotational direction of the integrated wood is clockwise, that is, it moves in the direction of the direction mark arrow, and the rotary knife of the rotary cutter rotates clockwise. The feeding direction moves opposite to each other, and the processing ends when the rotary cutting reaches the wood structure layer of the integrated wood core body, and the integrated wood core body can be reused.

[0060] To sum up, the application of the present invention provides a kind of integrated wood with a large diameter that can turn waste into treasure, and short and small boards and low-quality wood can be cut and spliced ​​reasonably to obtain large-diameter integrated wood, which can replace naturally grown large-diameter logs. It is processed into high-quality veneer ...

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 a kind of integrated wood and its manufacturing and utilization method, especially the method of using short and small boards and low-quality logs to process and manufacture large-diameter integrated wood, and 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 that is made of wood sections that are peeled into veneers or sliced ​​into thin wood, and then glued with adhesives. Usually, odd-numbered veneers are used, and adjacent layers of veneers are used. The fiber directions are glued perpendicular to each other. 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, it can generally overcome the defects of wood and greatly improve and enhance the physical a...
