Abstract

The present invention relates to a method for producing a multilayer veneer board. The chopped mao bamboo is cut into bamboo sections according to the required length; the bamboo sections are cut into bamboo sheets in the longitudinal direction; after four side surfaces of the bamboo sheets are planned and leveled, the four sides are glued and laminated into integrated materials; then, the integrated materials are sliced by a rotary slicer or a linear slicer to produce bamboo laminated veneers; then, the multilayer veneer board is manufactured by the gluing and the compounding of the bamboo laminated veneers and wood laminated veneers, or the multilayer veneer board is manufactured by the mutual compounding of the bamboo laminated veneers. The present invention can partially or completely substitute the multilayer veneer board for wood production by using bamboo, and the bamboo utilization rate is greatly increased.

Description

A kind of production method of multi-plywood

The invention belongs to the production method of glued board, particularly contain the production method of the glued board of bamboo veneer layer.

Multi-plywood is widely used in industries such as building, decoration, furniture manufacturing.Multi-plywood in the prior art adopts timber to make mostly.Because glued board uses, demand is big, causes a large amount of trees to be cut down, it is weary to cause the forest reserves to burst thus, and ecological environment is destroyed, and the harmfulness of natural calamity increases.Also have in the plywood production and adopt bamboo board, this bamboo board mostly is greatly and adopts bamboo chip a kind of bamboo veneer that gummed is pressed into behind planing and/or sand milling, so make, produce many planes, mill scrap, cause bamboo wood waste excessive, especially waste is bigger when to make thickness be bamboo veneer layer below 3 millimeters.

The objective of the invention is to the production method that provides a kind of multi-plywood for addressing the above problem, the method is produced glued board can save timber and bamboo wood consumption.

Technical solution of the present invention comprises monolayer material gluing superimposed mutually, wherein has this monolayer material of bamboo veneer layer, its special character is that described bamboo veneer layer is to produce like this: the mao bamboon after will cutting down is cut into the bamboo section by Len req, bamboo section longitudinally cutting is split into bamboo chip, with four gluing integrated timbers that are overlapped in the smooth back of side planing of bamboo chip, bamboo veneer layer is produced in described integrated timber slicing with slicer.

Described integrated timber can be to be the gluing integrated timber that is overlapped in center with the technology plug, and correspondingly, described slicer is the rotary planing cutter.

Described slicer also can be the straight line slicer, and integrated timber correspondingly need not embedding technology plug.

Produce bamboo veneer layer with the slicing of rotary planing cutter, should make its cross section of superimposed integrated timber near circular, promptly the envelope of cross section is circular this shape, so can reduce the slicing waste material.

It can be 0.15～4mm that its thickness of bamboo veneer is produced in the rotation slicing.

Produce bamboo veneer layer with the straight line slicer, should make its cross section of superimposed integrated timber is rectangle.

It can be 0.15～4mm that its thickness of bamboo veneer is produced in the straight line slicing.

The present invention can be gluing superimposed with bamboo veneer layer and layer of wood, and wherein bamboo veneer layer can be made overlay coating, also can not only make overlay coating but also make an interlayer.

The present invention also can all adopt bamboo veneer layer to glue together mutually and make multi-plywood.

Owing to having aberration between the bamboo chip that builds up integrated timber, the bamboo veneer layer face that slicing is become produces aberration, for reducing this aberration, bamboo chip can be selected branch by color and pick the gluing integrated timber that is overlapped in back.

The present invention produces multi-plywood owing to adopt bamboo veneer layer to substitute layer of wood, so can save consumption of wood significantly, reduces the trees cutting capacity; effectively protect forest resources; preserve the ecological environment, the harm of economization natural calamity can make bamboo resource better be developed simultaneously.The present invention so can reduce the smear metal waste material significantly, saves the bamboo wood consumption owing to the gluing integrated timber that is overlapped into of bamboo chip, produce the bamboo individual layer with rotary planing cutter or the slicing of straight line slicer again, and utilization rate of bamboo is greatly improved.The multi-plywood that the present invention produces, available bamboo veneer layer is made overlay coating, and face veneer hardness and fineness are greatly improved, and gives the native texture of the good sense organ in surface, helps applications such as decoration, furniture manufacturing.

Below in conjunction with description of drawings embodiment of the present invention.

Fig. 1 be fit to the rotation slicing by the gluing superimposed integrated timber schematic diagram of bamboo chip;

Fig. 2 is that Fig. 1 integrated timber is produced the bamboo veneer layer partial schematic diagram by the slicing of rotary planing cutter;

Fig. 3 produces the bamboo veneer layer partial schematic diagram by gluing superimposed integrated timber of bamboo chip and straight line slicing;

Fig. 4 is the multi-plywood schematic diagram that the present invention produces.

Be labeled as among the figure: 1 integrated timber, 2 technology plugs, 3 chucks, 4 bamboo veneer layers, 5 cutting knifes, 6 integrated timbers, 7 anchor clamps, 8 cutting knifes, 9 bamboo veneer layers, 10 bamboo veneer layers, 11 interlayers, 12 bottom surface layers.

The production method of 1 one kinds of multi-plywoods of embodiment, mao bamboon after the felling is cut into the bamboo section by Len req, bamboo section longitudinally cutting is split into bamboo chip, four smooth backs of side planing of bamboo chip bubble is boiled degreasing, selecting branch by the bamboo chip color picks to reduce aberration between bamboo chip, being that the center is gluing with bamboo chip with technology plug 2 again is overlapped into integrated timber 1, and makes the envelope of integrated timber 1 cross section circular with economization slicing waste material.It is that rotate in the axle center with technology plug 2 that the chuck 3 that is fixed in the rotary planing cutter with technology plug 2 two ends makes integrated timber 1, handles cutting knife 5 rotation slicings simultaneously and produces bamboo veneer layers 4.Intercept this bamboo veneer layer by required size, with gluing its upper layer of multi-plywood that is combined into of single wood plate layer be bamboo veneer layer 10, an interlayer 11 and bottom surface layer 12 are single wood plate layer.

This routine multi-plywood is not limited to described three layers, and interlayer and/or bottom surface layer also can be bamboo veneer layers therebetween.

The thickness of bamboo veneer layer generally can be 0.15～4mm, but is not limited thereto size.

The production method of a kind of multi-plywood of 2 examples of embodiment, mao bamboon after the felling is cut into the bamboo section by Len req, bamboo section longitudinally cutting is split into bamboo chip, four smooth backs of side planing of bamboo chip bubble is boiled degreasing, selecting branch by the bamboo chip color picks to reduce aberration between bamboo chip, make the cross section of integrated timber 6 become rectangle the gluing integrated timber 6 that is overlapped into of bamboo chip again, on the straight line slicer, move back and forth integrated timber 6 with anchor clamps 7 clamping integrated timbers 6, handle cutting knife 8 slicings simultaneously and produce bamboo veneer layer 9, be bamboo veneer layer 10 with this bamboo veneer layer and gluing its upper layer of multi-plywood that is combined into of single wood plate layer then, an interlayer 11 and bottom surface layer 12 are single wood plate layer.
