Other features and advantages of the present invention will the following detailed description will be given in the detailed implementation section.
Detailed description of the invention
The drawings are intended to provide a further understanding of the invention, and constitutes part of specification, with following tool
Body embodiment is used to explain the present invention together, but is not construed as limiting the invention.In the accompanying drawings:
Fig. 1 is a kind of selection process process figure of the invention.
Specific embodiment
Below in conjunction with attached drawing, detailed description of the preferred embodiments.It should be understood that this place is retouched
The specific embodiment stated is merely to illustrate and explain the present invention, and is not intended to restrict the invention.
As a preferred embodiment of the present invention, a kind of once hot pressing technique of composite board, such as Fig. 1
It is shown, using following steps:
Start glue mixer 11, after rubber made from soybean cake and wood fibre are mixed to uniformly, through travelling belt and tripper point
It is not transported to the feed bin of upper berth machine 13 and lower berth machine 10.
The glued board of with being placed in heap plate Kun platform 1 is displaced to Drum-type hydraulic lifting platform 2 with fork truck, in push plate device 3
Under effect, it is longitudinal into plate that glued board first passes through longitudinal Kun platform 4, then by laterally into plate Kun platform 5 laterally into plate；Using glue spreader 6
Double spread is carried out to glued board, the glued board after gluing moves to synchronous reciprocating air operated clamp by dish-style Kun platform transporter 7
Slab after gluing is further moved to the position that will mat formation, waiting is mated formation by machine 8.
It carries out layer mating formation, the glue stirred evenly and wooden fines is paved on to the glued board of gluing with lower berth machine 10
Lower surface, using more Kun preformers 9 by the pressure of setting, pre-molding lowermost fibre plate, the lower surface of the glued board of gluing
It is bonded with lowermost fibre plate；Using 8 doubling plywood side of synchronous reciprocating pneumatic clamps trigger, moves it to upper berth machine 13 and carry out
Surface layer is mated formation, i.e., correspondingly, the glue stirred evenly and wood fibre is paved on to the upper surface of the glued board of gluing, utilize more Kun
Cylinder 14 pre-molding top fiber plate of continuous preformer, the upper surface of the glued board of gluing and top fiber plate bond.
Further, carry out detection sorting, including Scanning Detction plate face density, by probe detection surface moisture content,
Using sensor sense weight, unqualified slab is isolated.
Once hot pressing is carried out to the qualified slab through detecting i.e. multi-layer board, specific steps include: to set multi-layer board
Enter in multi-daylight press 15, each multi-layer board is supported by a platform, quick-make multi-daylight press in 3~4s；15~
The pressure that boosting reaches 0.6Mpa~1.6MPa in 16s starts to be segmented hot pressing, is segmented during the entire process of hot pressing, temperature is maintained at
100 DEG C~200 DEG C, the segmentation includes:
