Description

Be used for method and continuously operating press in continuously operating press production plate of material

Technical field

The present invention relates to a kind of method and a kind of continuously operating press that is used to carry out this method as described in the preamble that is used in continuously operating press production plate of material as described in the preamble according to claim 14 according to claim 1.

Background technology

The production of particieboard and (for example) medium density fiber plate of material is automation process at present, and for many years in many national extensive uses.Described as " wood materials, produce with process " the 17th page of literary composition (DRW publishing house) and follow-up each page that Hansgert Soine delivered in nineteen ninety-five, according to certain rhythm, or suppress wood chip or fiber in a continuous manner through preprocessing.Except having many units before and after the press, outstanding role be to produce pressing blank by spreading machine; Yet except the quality of raw material, the quality of made pressing blank also is a key factor.

Produce pressing blank by by spreading machine treated material being mated formation in the preparatory stage to forming belt, the tenant activity area weight claims to check pressing blank and/or checks density then.In addition, in this class production equipment, usually also has magnetic separator and as the search coil of metal detector, the preformer that is used for pre-compacted, pressing blank longitudinal side trimming device and band is sent in the special use of the feed zone wedge shape compaction apparatus of pressing blank feed-in continuously operating press at last in the predefine position.In these press described in DE 39 13 991C2, by the hydraulic pressure guiding mechanism pressure is passed to pressing plate and heating plate, the ring steel belt that is supported by roller chain blanket (rolling bar) transfers the pressure on the pressed material then.

Prove that in the technical development of recent years the key component of continuously operating press is the feed zone zone.Two kinds of different in principle solutions have been summed up.A kind of solution that is used for accurately defining the feed zone curve is, arrange flexible feed zone heating plate in the feed zone zone, these feed zone heating plates can be regulated and therefore can cause more or less bigger feed zone gradient (DE 34 13 397) by hydraulic regulating device.An exemplary improvement project is, is clamped in pressing blank between the steel band apace in the feed zone zone and by causing in check exhaust etc. towards feedboard bending longitudinally.For this reason, above press, arrange the different preferred adjusting devices that works doubly, these adjusting devices along producer to different bending moments is introduced feed zone heating plate (DE 198 24 723C1).

Another kind method has been described the parallel development in feed zone zone.A kind of continuously operating press and a kind of quantity-produced method that is used for have been described among DE43 01 594C2, wherein described according to this patent disclosure specification, as a kind of so-called two-stage feed zone wedge shape compaction apparatus of the part of continuously operating press accept the pressing blank sent here from conveyer belt and according to predetermined main compaction curve feed zone by on steel band come these pressing blanks of powerful ground compacting.In the case, variable-angle control device by two backbars of playing pressing plate function of being hinged flexibly, in the feed zone zone, divide two pressing stages to come the compacting pressed material, wherein in first pressing stage, pressed material is carried out slight pressurization to brute force, and in second pressing stage, pressed material is carried out the brute force pressurization or sheds pressure.In the case, from first pressing stage to second pressing stage and the changeover portion from second pressing stage to main nip can be adjusted into and protrude or concave shape.DE 100 45 681A1 improve this feed zone wedge shape compaction apparatus, wherein used the known top of feed zone wedge shape compaction apparatus, it has two articulateds and two compacted region KV1 that separate and KV2, but below feed zone pressing plate begins integrated ground and is equipped with excessive radius of curvature regularly until main nip territory from the contact slab, can make its bending by hydraulic pressure short stroke cylinder.Therefore when using different pressing blank types and thickness, feed zone wedge shape compaction apparatus can be adjusted to essential parameter neatly.。

Usually in the feed zone of continuously operating press, use different compacting strategies now, wherein preferred or carry out compacting until the final thickness that reaches plate of material with linear fashion slowly from the contact pressing blank, or after the contact pressing blank, carry out quick compacting until almost reaching final thickness.These strategies directly depend on the height of the pressing blank that enters, the characteristic of pressing blank and the speed of production (rate of feed) of pressing blank.Can determine in principle: be used in the high pressing blank of producing thick plate of material (greater than 16mm) with less speed of production (usually less than 750mm/s) and pass through continuously operating press.The following thin material flitch of 16mm be by under pressure and the high temperature in continuously operating press short time of staying and therefore higher production cause.During thin plate below producing final thickness 4mm, using high feeding speed (until 2m/s) and compacting in case of necessity usually highly is the pressing blank through pre-compacted that 10mm arrives 100mm.In the case, in the feed zone wedge shape compaction apparatus in possible length reaches the feed zone zone of 4m pressing blank is densified near final thickness.In the feed zone zone of using the calendering press or adjusting relatively poorly or under the situation of the various types of feed zone wedge shape compaction apparatus of use, the compacting that is exceedingly fast may cause the pore of pressed material or oppositely block in continuous biobelt press.Pore is by producing to opposite moving air with producer, especially producing when the flow blockage of air occurring.Consequence is: the pore by the similar blast in cover layer place makes pressing blank fold or turnup, and these fold or turnup may cause local impaired (impression) at steel band place with the density of its increase.Consequence is: these rejected regions that must repair troublesomely can cause the poor surface quality that final products always reappear or the replacing of steel band occurs causing after a large amount of rejected regions in steel band in the steel band.

Experience shows, when producing MDF plate or particieboard in thick and thin Production Regional, only is applicable to the exhaust that reaches optimum under certain condition according to the feed zone wedge shape compaction apparatus of above-mentioned prior art and debulking methods so far or production method.This is to be caused by the huge amount air that is comprised in the pressing blank, and these air only can be discharged by preformer limitedly, because pressing blank tends to take place strain after preformer.Worse, in principle when the production plate of material by cover layer in less exhaust meeting before the slab contact point, occur causing the surface to form the dancing dervish of streak.If select speed of production high as far as possible, that rule of thumb cause bigger pore can not occur or only very rarely occur, can produce local higher flowing velocity by the air-flow of discharging at big face side place, this flowing velocity makes less cover layer zone be moved and it can be discovered as the micro-cracks in the cover layer.Except the wedge effect of micro-cracks, also produced poor surface quality problems herein, especially the poor surface quality problems when producing thin plate.

Summary of the invention

Now, task of the present invention is, a kind of method that is used at continuously operating press compacting pressing blank is provided, this method can be in the feed zone zone towards realizing the optimization exhaust of pressing blank in the opposite direction with producer and realizing simpler adjustment simultaneously to the feed zone zone.A kind of continuously operating press that is used to carry out this method also should be provided simultaneously.

Solution at described method is, during passing through the feed zone zone, at least along producer to a section in, from a face side utilization perpendicular to producer to straight line basically the feed zone heating plate or utilize at least two perpendicular to producer to the articulated slab of straight line basically clamp and/or the compacting pressing blank, and from the face side utilization of offside at least along clamping and/or this pressing blank of compacting perpendicular to the feed zone heating plate of producer the zone of the longitudinal centre line of pressing blank direction to bending.

The solution of task of carrying out the continuously operating press of described method at being used to of being proposed is, arranges the feed zone heating plate in the feed zone zone,

A) for crooked and/or arch upward, this feed zone heating plate at least at least a portion that is fixed on press rack on the position in the mode of power transmission and/or form fit and be arranged to by respective base crooked statically, and/or

B) arrange that for this feed zone heating plate a plurality of hydraulic regulating devices are so that support, and for this feed zone heating plate, for the pro rata at least bending of this charging heating plate and/or arch upward, along producer at least a portion adjusting device in the adjusting device group being arranged to have than bigger adjustable stroke of other adjusting devices in the adjusting device group and/or bigger adjustable pressure, and wherein between the part of press rack and feed zone heating plate, arrange withdrawing device together with baffle plate towards pulling back of press rack direction for this feed zone heating plate, and/or

C) arrange a plurality of hydraulic regulating devices so that the supporting of floating for this feed zone heating plate, and for this feed zone heating plate, for pro rata at least bending and/or arch upward, at least in a part of adjusting device of adjusting device group along producer to arranging the range bigger hydraulic regulating device of range than the adjusting device in the adjacent adjusting device group.

Except all three distinct device combination of features, also can distinguish independently and arrangement of features A individually) to C) so that the bending of feed zone heating plate.

Utilization according to the solution at described method and described continuously operating press of the present invention (also can operate dividually according to principle and described method independently in addition) at the solution of described continuously operating press can be the time with pressing blank production plate of material by cleaning more and continuous forced exhaust obtain following advantage.For this reason, preferably in longitudinal extension (along producer to) make the bending of feed zone heating plate so targetedly at the middle part of pressing blank obtain compacting higher or faster at the middle part so that compare with the narrow side of pressing blank.By compare with fringe region the center of pressing blank short or in case of necessity in addition the long period work suppress reality, air obtains vector and impacts, this impact to cover from producer to oppositely up to perpendicular to producer to angular range, this angular range is located substantially in the plane of pressing blank.Under thick or high pressing blank situation, this effect is brought advantage, but must benly be at this, can in the feed zone zone, carry out this type of in check exhaust to pressing blank, this pressing blank does not generate back-pressure or only generates less back-pressure the feed zone heating plate, perhaps only compacted or clamping in the initiation region of feed zone wedge shape compaction apparatus for the exhaust of optimum.This compress or clamp preferably carry out in stress-free mode almost and should prevent from this zone, on the face side of pressing blank, to discharge air-flow.Therefore, air-flow is forced to towards the skew of the direction of narrow side, and discharges from pressing blank there and contact with environment.The favourable design of described exhaust is particularly useful for height below 75mm, preferably the pressing blank below 40mm.Described method is applicable to that especially also speed of production surpasses the situation of 1m/s.

Compared with prior art finally obtain following advantage:

A) that in first compacting zone, on the leptoprosopy of pressing blank, obtain protective and exhaust through optimizing,

B) avoided pore in the top cover layer of pressing blank,

Therefore c) the supratectal dancing dervish of pressing blank does not directly appear at before the slab contact point, obtains optimum and surface texture and surface colour uniformly,

D) can check whether zone before the pressing blank top next-door neighbour slab contact point has pore or pressing blank too high by simple grating, this is usually because because of the dancing dervish that air caused of flowing out before the slab contact point but impossible, and

E) significantly reduced the fire hazard that causes because of dancing dervish in the feed zone.

Simultaneously, the continuously operating press that the method according to this invention was provided in being used for of newly providing still can continue to produce thick plate of material with the very high pressing blank that surpasses 75mm, and needn't stand with respect to the mass loss of production equipment so far.Therefore, the continuously operating press that newly provides also can successfully be operated under the situation of the method according to this invention independently need not, and wherein this continuously operating press has the feature of sign property.

With regard to the press technology, since nearly more than ten years, in the practice usually towards vertically or along producer always regulate or crooked feed zone zone in feedboard or articulated slab.Should reach optimum exhaust thus.In addition, in many diverse ways, also have different pressure parameters and compacting parameter to be subjected to generally paying attention to, for example in steam impringement technology targetedly, adopt relatively wet pressing blank, be used for respect to sandwich layer density regulate cover layer density different compacting features, or the like.

Show, be limited to keyword such as " wedge shape ", " tubaeform " or " taper " feed zone zone about the known principle of the bending of feedboard or articulated slab in the prior art.Last mentioned notion and the principle after the prior art are, the narrow side of powerful ground compacting pressing blank to be avoiding pore occurring in the narrow side, but these narrow sides by with producer to the exhaust of oppositely carrying out and described to steel band harm and on face side, cause pore once more with strengthening.In this type of feed zone feature, feedboard or articulated slab are mainly towards the vertical and horizontal bending.Herein, shortcoming especially is, carries out the multiaxis bending to can not easily operating the quite hard metallic plate that can not easily implement.

The present invention selects another kind of approach herein: preferred only feed zone heating plate with perpendicular to producer to mode crooked or be configured to crooked statically with formation arch upward or transverse curvature and make offside perpendicular to producer to the feed zone heating plate keep straight line or maintenance activity for its gradient (being static equally).This with towards the possibility of vertically regulating the feed zone feature does not contradict, this is by realizing towards the mode of buckling feedboard with the height in adjusting feed zone gap, though, should keep the linear straight line parallel in the horizontal with rolling bar because towards buckling the time, regulated for example crooked curve.Therefore, straight plane can not appear in the feedboard of bending.In contrast, articulated slab is not designed to regard to its essence perpendicular to producer usually to the ground bending, because may occur and the articulated slab subsequently or the articulated connectivity problem of pressing plate (main nip territory).For this reason, present principles especially can be applicable to such continuously operating press, and wherein the feed zone heating plate that is usually placed in the below of offside can have fixing feed zone radius in the vertical.This type of feed zone heating plate be particularly useful for perpendicular to producer to bending.
