And wood shavings laying apparatus and veneer apparatus for placing are respectively positioned on bottom and unreel between roller 1 and top layer unwinding device, wood shavings are laid with dress
It is multiple for setting with veneer apparatus for placing, and is provided with wood shavings laying apparatus between two adjacent veneer apparatus for placing, and
Bottom unreels setting wood shavings laying apparatus, top layer between roller 1 and adjacent veneer apparatus for placing and unreels roller 7 and adjacent list
Wood shavings laying apparatus is provided between panel assembly, top layer unreels roller 7 and top plate 27 is placed on the wood shavings layer of top layer；Into
One step, veneer apparatus for placing is two, and respectively the first veneer apparatus for placing 3 and the second veneer apparatus for placing 5, and second is single
Plate apparatus for placing 5 is located at 3 front of the first veneer apparatus for placing, and the first veneer apparatus for placing 3 places veneer and forms glued board
First ply 23, the second veneer apparatus for placing 5 place veneer and form the second ply 25 of glued board, wood shavings laying apparatus
It is three, and respectively the first wood shavings laying apparatus 2, the second wood shavings laying apparatus 4 and third wood shavings laying apparatus 6, wherein the
One wood shavings laying apparatus 2 is located between bottom unwinding device and the first veneer apparatus for placing 3, and the first wood shavings laying apparatus 2 is spread
If wood shavings and the first wood shavings layer 22 for forming glued board, the second wood shavings laying apparatus 4 is located at the first veneer apparatus for placing 3 and second
Between veneer apparatus for placing 5, and the second wood shavings laying apparatus 4 is laid with wood shavings and forms the second wood shavings layer 24 of glued board, third
Wood shavings device is located at the second single-board device and top layer unreels roller 7, and third wood shavings laying apparatus 6 is laid with wood shavings and forms gluing
The third wood shavings layer 26 of plate, in the present embodiment, the first wood shavings layer 22, the second wood shavings layer 24 and third wood shavings layer 26 use plane
It spends all the same, is that wood shavings are put into cloth glue application solution in glue mixer, is then aged, digestion time is not less than half an hour,
Glue of being subject to penetrates into wood shavings completely, when cloth glue application solution, fire retardant is added in wood shavings, to guarantee glue
The flame retardant property of plywood, in the present embodiment, wood shavings laying apparatus include wood shavings storage bin, are arranged in the bottom of wood shavings storage bin
There is an opening that wood shavings pass through, and the wood shavings in wood shavings storage bin are the wood shavings after sizing, in charity wood shavings, wood shavings are from opening
Outflow, and uniform charity is on corresponding bottom plate 21, the first veneer and the second veneer is led to defeated with conveying device 11
It send, to wood shavings, bottom plate, veneer, top plate are continuously laid with, to realize the continuous laying of glued board.
In the present embodiment, when glued board continuous laying completion axis, 11 discharge end of conveying device is provided with continuous precompressed
Machine 8, and continuous preformer 8 is located at the front that top plate unreels roller, glued board after the completion of laying, from the charging of continuous preformer 8
Mouth enters, with the gap shrinks between the pairs of roller group of continuous preformer 8, so that glued board is gradually squeezed, it will be fluffy
Glued board is pressed into fine and close glued board；
In the present embodiment, lath cutter 9 is located at the side of the discharge end of continuous preformer 8, and lath cutter 9 cuts glued board,
After glued board is by continuous 8 compression moulding of preformer, glued board is provided with certain structural strength, wood shavings, veneer, bottom plate and top
It has been bonded, therefore will not be scattered each other between plate, by lath cutter 9, continuous glued board is then cut to conform to requirement
Monolithic particieboard, still, particieboard at this time can not comply fully with production requirement, and the glue in glued board does not solidify,
Design requirement is not achieved in the structural strength of glued board, and glued board at this time can also be sprung back, so that the thickness of glued board can increase
Add, therefore then need to carry out hot pressing to glued board using hot press 10 to consolidate, further, hot press 10 is located at lath cutter 9
Side, and hot press 10 is the multiple press of heat-conducting oil heating, thermally conductive oil temperature is 180 DEG C ~ 200 DEG C, leads to heat transfer, glue
Glue in plywood is heated to solidify, and forms firm glued board, and under the effect of the pressure of hot press 10, glued board
Thickness then can further reduce, and ultimately form the glued board for meeting size.
In the present embodiment, the first veneer and the second veneer are laterally disposed, and veneer apparatus for placing, can use plate
Catching robot is realized, it is of course also possible to by manually placing the first veneer and the second veneer.
A kind of production technology of glued board, it the following steps are included:
