Abstract
This is a waviness end face extrusion head for the hollow shaving board extrusion press, characterized in that the press end face of the extrusion head belongs to one-D or two-D wave shaped camber. As compared with the extrusion shaving board made by the ordinary flat-face extrusion head, due to the change of extrusion head's end face, the straight line distribution no longer occurs between the layers of the raw materials although the stratiform still exists for the finished products. Also, grain direction of the raw materials is no longer perpendicular to the board face. The vertical static bending strength and the surface strength of the finished products could be raised to 20 to 30% respectively. Wastage (damage from the transportation) rate is also greatly lowered.
Description
One, technical field
The utility model belongs to the wood-based plate manufacturing process technology field in the timber industry.
Two, background technology
Along with global timber resource shortage, how efficiently to utilize wood machining residues and other plant raw material, be the research focus of wood-based plate industry all the time.Saw lumber residue, undersized log, brush wood and waste log etc. can be produced particieboard through processing.According to the difference of pressing process, particieboard can be divided into flat-press wood chipboard, roll-in particieboard and extruded wood chipboard three major types type.Adopt vertical or horizontal continuous extruding technology to produce extruded wood chipboard (Extruded Particleboard), because consumption glue amount is low, equipment investment is few, can make advantages such as particieboard, the distortion of the imbibition on the thickness direction of hollow be less, is widely used in furniture, door, platen, the manufacturing of particieboard of sound panel usefulness.
The physical and mechanical property of extruded wood chipboard is compared with concora crush or roll-in particieboard, because the restriction of extrusion process itself, the machine direction of raw material is approximately perpendicular to the plate face and distributes, and therefore, finished surface intensity is very low, could use after generally must handling through veneer.Another shortcoming of extruded wood chipboard is, because the restriction of extrusion process self, under the effect of planar end surface extrusion head, raw material vertically is the parallel lines layered distribution substantially plate, especially the extruding segmentation phenomenon that forms of planar end surface extrusion head reciprocating extrusion, cause vertical MOR of finished product particieboard very low, even cause difficult.
Three, summary of the invention
Purpose of design of the present utility model is at the process characteristic of extruded wood chipboard and the deficiency of performance, to seek a kind of flakeboard extruder extrusion head end surface shape that can obviously improve finished surface intensity and vertical MOR.
Technical solution of the present utility model is: the corrugated end face extrusion head of a kind of hollow flakeboard extruder, the extruding end face that it is characterized in that extrusion head are one dimension or two-dimentional corrugated curved surface.
Because the change of extrusion head end surface shape, though the finished product extruded wood chipboard still has stratiform segmentation phenomenon, the raw material between layer and the layer no longer is parallel lines and distributes; The machine direction of raw material is no longer distributed perpendicular to the plate face, improved the vertical MOR and the surface strength of finished product greatly.
Four, description of drawings
Fig. 1 is the operation principle schematic diagram of ordinary particle board extruder.(1) is heating platen among the figure, and (2) are extrusion head, and end face is the plane, and (3) are the extruded wood chipboard slab, and (4) are the post of finding time.When not using the post of finding time (4), can produce solid extruded wood chipboard finished product;

Fig. 5 is two-dimentional corrugated curved surface extrusion head side view, and the r among the figure is a side ripple radius.
For the purpose of expressing clearly, all do not draw the post hole of finding time in Fig. 2～5.
Five, the specific embodiment
Embodiment 1:
Vertical or horizontal flakeboard extruder adopts the corrugated curved surface extrusion head of one dimension shown in the accompanying drawing 2,3, and producing thickness with the speed of 0.4～0.5m/min is the hollow or solid extruded wood chipboard of 33mm.The ripple height h=10mm of extrusion head, wave amplitude L=135mm, ripple adopts sine curve.
Embodiment 2:
Vertical or horizontal flakeboard extruder adopts the corrugated curved surface extrusion head of one dimension shown in the accompanying drawing 2,3, and producing thickness with the speed of 0.4～0.5m/min is the hollow or solid extruded wood chipboard of 33mm.The ripple height h=10mm of extrusion head, wave amplitude L=135mm, ripple adopts the straight line sawtooth pattern.
Embodiment 3:
Vertical or horizontal flakeboard extruder adopts the two-dimentional corrugated curved surface extrusion head shown in the accompanying drawing 4,5, and producing thickness with the speed of 0.4～0.5m/min is the hollow or solid extruded wood chipboard of 33mm.The ripple height h=10mm of extrusion head, wave amplitude L=135mm, ripple adopts sine curve; Side ripple radius r=16.5mm, the side ripple adopts circular curve.
Embodiment 4:
Vertical or horizontal flakeboard extruder adopts the two-dimentional corrugated curved surface extrusion head shown in the accompanying drawing 4,5, and producing thickness with the speed of 0.4～0.5m/min is the hollow or solid extruded wood chipboard of 33mm.The ripple height h=10mm of extrusion head, wave amplitude L=135mm, ripple adopts the straight line sawtooth pattern; Side ripple radius r=16.5mm, the side ripple adopts circular curve.
Embodiment 5:
As the corrugated curved surface extrusion head of embodiment 3,4 described two dimensions, be characterized in that the side ripple adopts the arc-shaped concave curve.
Adopt the utility model to produce extruded wood chipboard, with the extruded wood chipboard phase of common planar end surface extrusion head production Ratio, because the change of extrusion head end surface shape, although the finished product extruded wood chipboard still has stratiform segmentation phenomenon, But raw material between layers no longer is parallel lines to distribute; Also can make the machine direction of raw material no longer vertical Distribute in the plate face, it is about 20～30% that vertical MOR of finished product and surface strength can improve respectively, and technology is decreased Consumption (the disconnected plate rate of carrying) also reduces greatly.
