Description

The process of solid wooden compound floor bent plate alignment

Technical field

The invention belongs to the processing technique field of solid wooden compound floor, more particularly to a kind of solid wooden compound floor bent plate alignment Process.

Background technology

Solid wooden compound floor is in process of production, it may appear that it is convex stick up or it is recessed stick up exceeded bent plate, most of enterprise is using weight Thing pressurization, twisted plate is forced to face opposite direction bending, pressing time needs 15-30 days, to reach the effect of alignment, but again After thing is laid down, because elasticity is recovered, most of bent plate or exceeded, if bent plate, which is done, scraps or change chi processing, production cost is caused Significant wastage.

The content of the invention

To solve above mentioned problem present in prior art and actual conditions, the invention provides a kind of solid wooden compound floor The process of bent plate alignment, dry pressurization or roller pressurization shrinkage method using returning；

The baking pressurization of returning comprises the following steps,

1) slab is put into multi-daylight press, every layer of lay out in parallel be not overlapping, as far as possible placed in the middle, closes but is not pressurized, and presses Power is set to " 0 ", 100-105 DEG C of temperature, time 5-10min；

2) slab is taken out, slab is put into special alignment inframe while hot, all around alignment stacks into 1 along its length Pile, it is placed side by side per pile, gap is left between pile and pile, is topmost existed along plate width direction per every recessed warping of plate plate face of pile down Traverse one opens backing plate at length centerline, and width just enough puts jack base, and length just all pushes down every pile slab, thickness Moderate, backing plate used after pressure by can not destroy；

3) it is put in using 50T hydraulic jacks at backing plate center, alignment frame upper beam is withstood in pressurization, is given to slab one towards phase The active force of opposite direction bending, after keeping pressurization 24h, slab is taken out, alignment finishes；

The special alignment frame includes chassis, vertical beam and upper beam, and the chassis be rectangle structure, including crossbeam with indulge Beam, the vertical beam are connected to the centre position of longeron, and the upper beam is connected to the top of two vertical beams；

The roller pressurization shrinkage method comprises the following steps, and the convex warping of slab is put by the solid roller of irony, rolling upward The parallel axial direction of wheel surface has not equidistant, intermittent elongate strip raised, and height of projection 0.10mm-0.20mm, slab is by rolling After wheel, surface is extruded elongate channel trace under projection, and wood skin shrinkage produces pulling force, slab is stretched in the opposite direction, and will not be anti- Bullet.

Preferably, it is 20mm to return gap described in baking pressurization step 2).

The process of solid wooden compound floor bent plate alignment of the present invention, can manage it and effectively solve the problems, such as bent plate, reduce school The straight time, reduce loss, the present invention using return dry pressurization and roller pressurization shrinkage method can effectively be straightened it is convex stick up or recessed crosswise concaving plate, Return and dry pressurization pressurization 1 day, roller pressurization shrinkage method can be straightened by roller, the bent plate bending after two methods alignment Spend up to standard, will not rebound, reduce bent plate loss.

Brief description of the drawings

Fig. 1 is the structure of the special alignment frame of the process of the solid wooden compound floor bent plate alignment of the embodiment of the present invention 1 Schematic diagram.

Fig. 2 is that the structure of the roller devices of the process of the solid wooden compound floor bent plate alignment of the embodiment of the present invention 2 is shown It is intended to.

Embodiment

Embodiment 1：

Return baking pressurization

1) slab specification 1225*175*15.2mm, plate face is recessed to stick up angularity more than 5 ‰.Surface layer is that 1.2mm thickness toothed oak is wooden, bottom Layer is 0.6mm thickness beeches, and intermediate layer is solid wooden compound floor glued board, 7 layers of crisscross structure.Adhesive used is thermosetting Property adhesive.

2) slab is put into multi-daylight press, every layer of lay out in parallel be not overlapping, as far as possible placed in the middle, closes but is not pressurized, and presses Power is set to " 0 ", 100-105 DEG C of temperature, time 5-10min.

3) take out slab, slab be put into special alignment inframe while hot, both ends respectively on crossbeam, along its length before Rear left Right Aligns stacks into 1 pile, 4 pile placed side by side, 20mm gaps is stayed between pile and pile, per every recessed warping of plate plate face of pile down, Topmost along plate width direction, traverse one opens backing plate at length centerline, and width just enough puts jack base, and length is just complete Portion pushes down 4 pile slabs, and thickness is moderate, and backing plate used after pressure by can not destroy.

4) it is put in using 50T hydraulic jacks at backing plate center, alignment frame upper beam is withstood in pressurization, is given to slab one towards phase The active force of opposite direction bending, after keeping pressurization 24h, slab is taken out, alignment finishes.

As shown in figure 1, the special alignment frame includes chassis, vertical beam 3 and upper beam 4, the chassis is rectangle structure, bag Crossbeam 1 and longeron 2 are included, the vertical beam 3 is connected to the centre position of longeron 2, and the upper beam 4 is connected to the top of two vertical beams.

Embodiment 2：

Roller pressurization shrinkage method

1) slab specification 1225*175*15.2mm, plate face is convex to stick up angularity more than 5 ‰.Surface layer is that 1.2mm thickness toothed oak is wooden, bottom Layer is 0.6mm thickness beeches, and intermediate layer is solid wooden compound floor glued board, 7 layers of crisscross structure.Adhesive used is thermosetting Property adhesive.

2) the convex warping of slab is put by the solid roller of irony upward, the parallel axial direction of roller surface has not equidistantly, absolutely Continuous elongate strip is raised, height of projection 0.15mm, and for slab after roller, surface is extruded elongate channel trace, wood skin wrinkle under projection Contracting produces pulling force, and slab is stretched in the opposite direction, and will not rebound.

As shown in Fig. 2 the roller devices include roller 5 and feeding station 6, the slab is by between roller 5 and feeding station 6 By being respectively equipped with dynamical system in the roller 5 and feeding station 6.

When paying attention to placing slab, convex warping is put upward and pushed by roller, shrinkage pulling force in surface can just stretch slab.

Finally it should be noted that：The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention, Although the present invention is described in detail with reference to the foregoing embodiments, for those skilled in the art, it still may be used To be modified to the technical scheme described in foregoing embodiments, or equivalent substitution is carried out to which part technical characteristic. Within the spirit and principles of the invention, any modification, equivalent substitution and improvements made etc., it should be included in the present invention's Within protection domain.
