Fig. 2 is the production procedure schematic diagram of new laminated veneer lumber.
As shown in Figure 2: production procedure of the present invention is:
At first the veneer drying of sizing is handled and tiltedly milled machine 1 by the abrasive band and become the inclined-plane at vertical two end mills of veneer, stand-by.(veneer length will have size Control, generally gets negative common difference)
By the surface coating of 4 pairs of veneers of glue spreader, wherein the veneer of the superiors need not gluing then.
It then is the assembly process, walking dolly 15 moves from right to left, begun the position 0 of right side, this moment is backer 16 placement first veneers (glue towards last) of glue-coated veneer by dolly, press gauge tap, backer 16 rises under the effect of cylinder, then under the effect of motor, walking dolly 15 (promptly left) forward moves a given displacement L, the cylinder action, backer 16 presses down, and place second veneer this moment, presses gauge tap and repeats above action, finish mating formation of second veneer, realize the unlimited spreading of veneer assembly by that analogy, wherein, walking dolly 15 (promptly left) mobile given displacement L forward can be adjusted voluntarily according to client's needs.In general, the size of L and the total height of laminated veneer lumber and the number of plies have relation, to guarantee between all layers of laminated veneer lumber that no matter the seam distance where is identical, after reaching the required veneer number of plies of certain thickness, backer 16 gets back to original position, simultaneously the position of a veneer of advancing of the veneer on the assembly platform 13.
Later process behind assembly is for colding pressing, and when the veneer on the front assembly platform 13 advanced a veneer position, veneer preformer 6 was in the beginning position; And when being in the assembly process, veneer preformer 6 presses down, because the length of veneer preformer 6 is greater than the twice of veneer length, therefore in the assembly process, the intact veneer of all assemblies all can obtain above cold pressure procedure twice.
Become the significantly area of certain-length to become sheet material by portable amputating saw 11 according to the length specification cross cut saw of required laminated veneer lumber at last, promptly at first, the length L of the assembly plate that blocks as required, the distance of the positive stop 122 on the fixed length pull bar 121 will be adjusted, make that the distance between itself and the saw blade 116 is the needed length L of assembly plate, then, when the front end of assembly plate moves to the position of positive stop 122, not if (promptly the length of a veneer also there is not end) that the assembly plate of this moment still moves, then the assembly plate compresses positive stop 122, it drives portable amputating saw 11 integral body and travels forward, promptly under the thrust of assembly plate, walking forward on roller on its frame 112 track 111 on the ground, until the stop motion of assembly plate, then, saw blade lift cylinder 117 is pneumatic, it promotes saw blade 116 to cutting position, the motor of sawing simultaneously 115 also starts, beginning is carried out sawing with the assembly plate, and this moment, movable motor 119 also starts, it drives saw cutting mechanism integral body by saw blade walking mechanism 118 and travels forward, and then the horizontal sawing of 116 pairs of whole assembly plates of realization saw blade, after sawing was finished, portable amputating saw 11 retreated into original position.
Above-mentioned assembly plate through sawing enters carries Kun 12, becomes sheet material to change hot pressing over to, carries rim charge, sanding processing, side sanding and the packing etc. of going to both sides by carrying the significantly area after Kun 12 will cold pressing.
Below disclose the present invention with preferred embodiment, so it is not in order to restriction the present invention, and all employings are equal to replaces or technical scheme that the equivalent transformation mode is obtained, all drops within protection scope of the present invention.
