Background technology
See Fig. 1 and Fig. 2, continuous press 100 has a press top 110 and a press bottom 120, also there is upper and lower steel band 130,140 and the upper and lower roll bar chain blanket 150,160 of running continuously in press top 110 and press bottom 120, in press top 110 and press bottom 120, be respectively arranged with upper and lower feeding heating platen 170,180, upper and lower steel band 130,140 forms a charging profile 191 entering the position between upper and lower feeding heating platen 170,180.A binder passage 192 is formed between upper and lower feeding heating platen 170,180.The feed end of binder passage 192 is connected in nature transition with charging profile 191.
During work, be looped around the upper steel band 130 of driven roller 131 and upper driving roller 132 and be looped around the lower steel band 140 of lower driven roller 141 and lower driving roller 142 upper, lower driving roller 132, shuttling movement is made under the driving of 142, by fibre blank 200 to be pressed along with upper, lower steel band 130, 140 shuttling movements and be sent to by upper, lower steel band 130, in the charging profile 191 formed between 140, enter into by upper again, lower feeding heating platen 170, the binder passage 192 formed between 180 is also pressed into the fibrous plate of all size in follow-up compacting passage 193.
In order to make to form rolling friction between upper and lower steel band 130,140 and upper and lower feeding heating platen 170,180, reduce running resistance, during work, the top roll bar chain blanket 150 being looped around cochain blanket drive sprocket 151 and cochain blanket driven sprocket 152 and the lower roll bar chain blanket 160 being looped around lower chain blanket drive sprocket 161 and lower chain blanket driven sprocket 162 also make shuttling movement under the driving of upper and lower chain blanket drive sprocket 151,161, enter between upper and lower feeding heating platen 170,180 and upper and lower steel band 130,140.
As a rule, upper, lower feeding heating platen 170, be configured with in 180, lower heater (not shown), on, heat passes through upper by lower heater, lower feeding heating platen 170, 180, on, lower roll bar chain blanket 150, 160 and upper, lower steel band 130, 140 are passed in the fibre blank 200 to be pressed in binder passage 192, make the adhesive solidification in fibre blank 200 to be pressed, pressue device 111 simultaneously on press top 110 is to upper, lower feeding heating platen 170, 180 apply pressure, and by upper, lower roll bar chain blanket 150, 160 and upper, lower steel band 130, 140 are passed in the fibre blank 200 to be pressed in binder passage 192, fibre blank 200 is progressively densified to the thickness preset, and through follow-up compacting passage 193, final formation fiberboard is sent.
Binder passage 192 between upper and lower feeding heating platen 170,180 is can be controlled, can suppress the different fibrous plate of thickness, as the fibrous plate of 12mm, 16mm, 25mm thickness to make a continuous press 100.
The upper and lower feeding heating platen 170,180 of current continuous press 100 only has a temperature province, fibre blank 200 to be pressed is entered in binder passage 192 by charging profile 191 and is cured in pressing process, owing to being subject to HTHP, the upper and lower surface of fibrous plate can form one deck pre-hardening thickness.As a rule, the upper and lower surface of the fibrous plate after compressing needs to carry out sanding process, remove the pre-hardening thickness on the upper and lower surface of fibrous plate, finally make the hardness of fibrous plate on whole cross section of dispatching from the factory substantially reach unanimity (as shown in Figure 3).Such as after compressing and the final thickness removing pre-hardening thickness is for the fibrous plate of 12mm, the thickness of the pre-hardening thickness on upper and lower surface will reach 0.45mm, and the fibrous plate thickness that namely continuous press 100 suppresses will reach 12.9mm.So thick pre-hardening thickness means: 1, waste of raw materials is serious, makes manufacturing cost high; 2, sanding amount is large, and the abrasive band of grinding consumes and sanding apparatus power consumption increases greatly; 3, sanding produces a large amount of dust, and work for the treatment of amount is large, also brings safety problem simultaneously.
The thickness of the pre-hardening thickness on the upper and lower surface of the fibrous plate after compressing, except relevant with the performance of the adhesive applied in fiber condition and fiber, the press temperature being subject to upper and lower feeding heating platen 170,180 with the charging rate of fibre blank 200 to be pressed, fibre blank 200 to be pressed in pressing process is relevant with pressing pressure.Fibre blank 200 to be pressed is when certain charging rate and press temperature, the pressing pressure that fibre blank 200 to be pressed is subject to upper and lower feeding heating platen 170,180 is lower, the pre-hardening thickness on the upper and lower surface of the fibrous plate after compressing is thicker, otherwise, the pressing pressure that fibre blank 200 to be pressed is subject to upper and lower feeding heating platen 170,180 is higher, and the pre-hardening thickness on the upper and lower surface of the fibrous plate after compressing is thinner.Technical staff in industry normally by strengthen pressing pressure reduce compressing after the thickness of pre-hardening thickness on upper and lower surface of fibrous plate, but this method can cause the fibrous plate after compressing forms dust spot.
Because fibre blank to be pressed 200 is in solidification pressing process, need to discharge a large amount of gas, these a large amount of gases discharged are discharged from the both sides of binder passage 192 on the one hand, another part has progressively solidified and has been compacted due to the fibre blank 200 of binder passage 192 rear end, (as shown in Figure 4 and Figure 5) can only be discharged to charging profile 191 direction, this part gas of discharging to charging profile 191 direction can upper, lower steel band 130, 140 positions contacted with fibre blank 200 to be pressed produce swirling air stream, swirling air stream acts on the upper of fibre blank 200 to be pressed, lower surface also produces a large amount of dust groups 10, the lower surface (as shown in Figure 6) of fibre blank 200 especially to be pressed, and these dust group 10 is brought in binder passage 192, due to these dust group 10 be subject to high temperature gas flow impacts often make dust roll into a ball in adhesive premature cure, cannot be fused in fibre blank 200 to be pressed and define dust spot on the surface of compressing fibrous plate.
At present in order to solve the problem of the dust spot on compressing fibrous plate, normally upper feeding heating platen 170 is being promoted certain height near the position of binder passage 192 import and I position, place of Fig. 7, upper feeding heating platen 170 is made to form " S " type curved surface with the approach axis of fibre blank 200, make to form an exhaust gap 194 in position, I place when suppressing between upper feeding heating platen 170 and lower feeding heating platen 180, a large amount of gases that fibre blank 200 to be pressed produces in solidification pressing process are discharged to both sides via this exhaust gap 194, so just effectively reduce the flow of this part gas of discharging to charging profile 191 direction, force to charging profile 191 direction discharge this part gas cannot upper, lower steel band 130, 140 positions contacted with fibre blank 200 to be pressed produce swirling air stream, thus the generation effectively reducing dust group or the generation avoiding dust to roll into a ball, this way can improve charging rate in addition, improve output.But, this way can increase compressing after the thickness of pre-hardening thickness on fibrous plate surface.

Detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
See Fig. 1 and Fig. 2, continuous press of the present invention is roughly the same with existing continuous press, there is a press bottom 110 and a press top 120 equally, also there is in press bottom 110 and press top 120 the upper of running continuously, lower steel band 130, 140 and on, lower roll bar chain blanket 150, 160, be respectively arranged with in press bottom 110 and press top 120, lower feeding heating platen 170, 180, on, lower steel band 130, 140 on entering, lower feeding heating platen 170, position before 180 forms a charging profile 191, on, lower feeding heating platen 170, a binder passage 192 is formed between 180.
Continuous press of the present invention and existing continuous press difference are: see Fig. 8, the binder passage formed between upper and lower feeding heating platen 170,180 is divided into the consolidation zone 192b and compacting but non-consolidation zone 192a that normally suppress, the consolidation zone 192b of normal compacting by this compacting but non-consolidation zone 192a be connected with charging profile 191, fibre blank namely to be pressed is introduced into compacting but consolidation zone 192a does not enter the consolidation zone 192b of normal compacting again.The temperature of adhesive normal cure of the deficiency of time that compacting but temperature not set by consolidation zone 192a and fibre blank 200 to be pressed pass through in fibre blank 200 to be pressed and the time of needs, thus, when fibre blank 200 to be pressed is through compacting but in the process of not consolidation zone 192a, the thickness of fibre blank 200 to be pressed is compressed but adhesive is wherein uncured.Particularly, compacting but not consolidation zone 192a temperature should lower than the adhesive of fibre blank 200 to be pressed by suppress but not consolidation zone 192a time the temperature of normal cure that needs.
In order to realize suppressing but the not temperature of normal cure that needs when by compacting but not consolidation zone 192a lower than the adhesive of fibre blank 200 to be pressed of the temperature of consolidation zone 192a, can by to suppress but consolidation zone 192a does not carry out cooling realization.Particularly, region between upper and lower feeding heating platen 170,180 is divided into the first temperature-controlled zones 310 and the second temperature-controlled zones 320, and the first temperature-controlled zones 310 and the second temperature-controlled zones 320 control separately respectively, as shown in Figure 9, wherein, first temperature-controlled zones 310 of upper and lower feeding heating platen 170,180 corresponds to compacting but not consolidation zone 192a, and the second temperature-controlled zones 320 on upper and lower feeding heating platen 170,180 corresponds to the consolidation zone 192b of normal compacting.
In addition, realize compacting but not consolidation zone 192a temperature lower than fibre blank 200 to be pressed adhesive by suppress but not consolidation zone 192a time the mode of the temperature of normal cure that needs can also be: by not to upper, lower steel band 130, 140 not to heat in consolidation zone 192a process through compacting, because on, lower steel band 130, 140 enter in binder passage 192 from the entrance point of binder passage 192 from doing shuttling movement after the port of export of binder passage 192 stretches out again, in the process, on, lower steel band 130, 140 obtain cooling owing to not being subject to heating devices heat effect, on, lower steel band 130, the temperature of 140 reduces greatly, thus by suitably adjusting and can ensureing, lower steel band 130, the temperature of the normal cure that 140 temperature when reentering in binder passage 192 need when by compacting but not consolidation zone 192a lower than the adhesive of fibre blank 200 to be pressed.
The work that continuous press of the present invention carries out compressed fibre blank is as follows: be looped around the upper steel band 130 of driving roller and upper driven roller and be looped around the lower steel band 140 of lower driving roller and lower driven roller upper, shuttling movement is made under the driving of lower driving roller, by fibre blank 200 to be pressed along with upper, lower steel band 130, 140 shuttling movements and be sent to by upper, lower feeding heating platen 170, in the charging profile 191 formed between 180, and successively by compacting but not consolidation zone 192a, the i.e. consolidation zone 192b of the first temperature-controlled zones 310 and normal compacting, i.e. the second temperature-controlled zones 320, wherein, the pressure when pressure of fibre blank 200 when by compacting but not consolidation zone 192a and consolidation zone 192b by normally suppress is equal or lower than pressure when passing through the normal consolidation zone 192b suppressed.
Due to fibre blank 200 to enter the consolidation zone 192b of normal compacting by charging profile 191 before, first a compacting is entered into but non-consolidation zone 192a, air in such fibre blank 200 can not to be discharged to both sides and charging contour direction in consolidation zone 192a in compacting, the gas that fibre blank in the consolidation zone 192b of normal compacting simultaneously produces in press curing process is discharged from the both sides of the consolidation zone 192b of normal compacting on the one hand, another part then can not to discharge in consolidation zone 192a to compacting, as shown in Figure 10, adhesive due to compacting but not in consolidation zone 192a is not cured, gas can be discharged smoothly, finally make on the fibrous plate after suppressing, the thickness of the pre-hardening thickness of lower surface at least can reduce 30% ~ 40% relative to prior art, even only have 30% of prior art, as shown in figure 11, thus saved raw material greatly, decrease sanding amount and reduce sanding apparatus power consumption and abrasive band consumption, reduce the dust that sanding produces.
In addition, due to fibre blank 200 through compacting but not the adhesive of consolidation zone 192a do not reach and solidify completely, the gas that fibre blank 200 discharges at the consolidation zone 192b of normal compacting can via compacting but not discharged to charging profile 191 direction by consolidation zone 192a, and this part gas is not enough to upper, lower steel band 130, 140 positions contacted with fibre blank 200 to be pressed produce swirling air stream, even if create swirling air stream, make the upper of fibre blank 200 to be pressed, lower surface creates its adhesive and uncured dust 10 (as shown in Figure 6) of group, and these dust group 10 is brought into compacting but not in consolidation zone 192a, because the adhesive of fibre blank 200 to be pressed is in compacting but not solidification in consolidation zone 192a, these dust group 10 can merge on the surface of fibre blank 200 to be pressed, thus the surface avoiding fibrous plate forms dust spot.
In addition, certain distance can also be promoted by the position, I place be in Fig. 7 in the position of the import near binder passage 192 by the upper pressue device 111 on press top 110, making upper feeding heating platen 170 form " S " type curved surface with the approach axis of fibre blank 200, making to form an exhaust gap 194 (see Fig. 7) in position, I place when suppressing between upper feeding heating platen 170 and lower feeding heating platen 180.Fibre blank 200 so to be pressed in compacting but the gas do not produced in consolidation zone 192a and the consolidation zone 192b of normal compacting produce and to compacting but a large amount of gases of consolidation zone 192a discharge can discharge via the both sides of exhaust gap 194 to fibre blank, effectively reduce the flow of the gas of discharging to charging contour direction, avoid the formation of vortical flow, so just suitably can accelerate charging rate, improve output.
