Description
Technical field
The present patent application relates to a kind of integrated wood and manufacturing thereof and utilizes method, particularly utilizes method short, the integrated wood of little sheet material and the big footpath of low-quality log processing and manufacturing, the integrated wood that the present patent application also relates to method gained thus with and uses thereof.
Background technology
Glued board is to be peeled into veneer or to be become veneer by the flitch slicing by juggle, sticks with glue three layers or the board-like material of multilayer that the agent gummed forms again, uses the odd-level veneer usually, and the orthogonal gummed of machine direction of adjacent layer veneer is formed.Glued board is main material production with timber, because the reasonability of its structure and the retrofit in the production process, can overcome the defective of timber substantially, improve the physical and mechanical property of timber greatly, be an important method sufficiently and reasonably utilizing timber, improve wood performance.
As everyone knows, plywood production is to utilize big footpath level log to make veneer, and the veneer quality has determined the quality and the production efficiency of glued board to a great extent, and has determined the quality of veneer basically for the raw material of producing veneer.At present in worldwide, because the over-exploitation of the forest reserves, cause supplying with the big footpath level wildwood resource that glued board uses and sharply reduce, the situation of China is more outstanding, and the raw material imbalance between supply and demand increasingly sharpens.For keeping the development of plywood industry, on the one hand a large amount of imported logs and veneer, have to use short, Logs of small diameter manufacturing veneer on the other hand, and low, the broken plate of narrow, the whole plate rate of veneer breadth, slashings that log directly little, the matter difference is produced are many, in plywood production, to spend a large amount of man-hours and go arrangement, splice these veneers, simultaneously when assembly, also can produce folded core, every the phenomenon of core, have a strong impact on the quality and the production efficiency of glued board.
For above-mentioned these problems, make great efforts from many aspects in the industry, from improving the process equipment performance as using advanced no axis, the path peeler, though improved the log volume recovery, but the quality of veneer does not still have basic improvement, Chinese patent CN17183874 disclosed " sham wood and manufacture method thereof " and for example, this method obtains the veneer piece by the rotary-cut Logs of small diameter, obtain whole Zhang Lianxu veneer by splicing again, be pressed into sham wood through adding hot rolling, then artificial log is carried out rotary-cut and make veneer, but this method is to utilizing the Logs of small diameter manufacturing broken plate that veneer produced, the problem that slashings is many still exists.
Summary of the invention
The present patent application promptly is at existing technology, and a kind of weak point, the method for the integrated wood of little sheet material and the big footpath of low-quality log processing and manufacturing and integrated wood of gained of utilizing is provided, and this integrated wood can be made wide format, whole Zhang Lianxu veneer through rotary-cut.
Specifically, the present patent application provides a kind of integrated wood, it is characterized in that: described integrated wood is made of with the integrated wooden monomeric adhesion that is enclosed within a plurality of annulars on the core body the columned core body at center, wherein,
1, core body is made of the cylindric metal inner core of closed at both ends and one deck timber structure layer of being close to the metal inner core;
2, the inner and outer rings of the integrated wooden monomer of each annular is a donut, wherein, the outer toroid equal diameters of each integrated wooden monomer, interior circle diameter is slightly larger than the diameter of described integrated reel body, and each integrated wooden monomer is that the fan-shaped blank splicing by a plurality of uniform thickness is bonded;
3, every block of fan-shaped blank is to be spliced after cutting forms by polylith uniform thickness, smooth sheet material jigsaw applying glue, the central angle of every block of fan-shaped blank is between 5 °-25 °, the edges of boards of sheet material of forming fan-shaped blank are vertical with a hypotenuse of fan-shaped blank, every block of fan-shaped blank is printed with tangible direction signs arrow figure, and the direction of arrow is pointed to this hypotenuse vertical with edges of boards;
4, the direction signs direction of arrow on the integrated wooden monomer of each layer annular of the integrated wood of composition is identical, and the integrated wooden monomer of multilayer is enclosed within on the core body, and applying glue laminates makes described integrated wood.
Described integrated wood is provided with the relative positioning means for positioning that tightens with the peeler dop at the two ends of metal inner core, described positioner is for integrated wood is clamped on the peeler, and can be around the axle center rotation of integrated wood, so that finish rotary-cut work smoothly.
