Description
Technical field
The present invention relates to a kind ofly by claim 1 method as described in the preamble, be used for forming bulk pad making the process of composite wood boards by pressure on the extruder and heat from bulk cargo, wherein, bulk cargo is made up of wood-fibred, wood chip or this class particle.The present invention relates to a kind of by the described forming station that is used to implement this method of claim 10 preamble in addition.
Background technology
With dispersible material manufactured materials plate the time; the compound of being made up of particle or fibrous material and binding agent is scattered in a bulk pad on a moulding or conveyer belt; wherein, preliminary treatment of the bulk pad necessity of carrying subsequently and 2 times of suppressing at last.Being compressed in this respect can by pressure and heat be continuous or discontinuous carrying out.The MDF plate formed by medium density fiber generally speaking of the common materials plate of Zhi Zaoing or the OSB plate of forming by the wood chip or the chips of directed cloth in this case.Cloth divides individual layer or multilayer to carry out as required, and wherein, thicker plate needs the multilayer cloth usually.Can carry out two kinds of different clothes on the cloth station: direct cloth after the bulk bin wherein, directly is directed at bulk cargo on the moulding band by stock guide, perhaps by the indirect cloth of so-called distribute roll system.When indirect cloth, the bulk cargo of discharging from bulk bin drops on the so-called distribute roll, and it is divided bulk cargo equally and also classifies when needed.Employed in this regard cloth is arranged in the patent documentation existingly extensively to be introduced, wherein, perhaps with bulk cargo carry out on the distribute roll that the center feeds intake or with the end of bulk cargo at distribute roll on feed intake.In this regard, a part of fiber continues to transport, and another part is then fallen on the moulding band through distribute roll, also must remove from production process until remaining inapplicable bulk cargo.Two kinds of principles prove effective and the application of succeeding producing slab and produce conditionally in the thin plate.
In plate of material production evolution in recent years, the trend of mixing timber appears using.The early stage MDF of US and European makes main use coniferous tree and carries out also carrying out like this with some areas, thus unified fiber mixture is used for processing and manufactured materials plate.Because these area, continent production equipment market saturations, so the new equipment order begins to shift to the Near East and Asia.There, elementary timber processing concentrates on the mixed forest, thereby no matter the equipment that will build is that coniferous tree or broad leaf tree must all can be processed.In this regard, coniferous tree and broad leaf tree have obvious difference aspect wood chip, fiber or the chips being processed into.The composite fibre of homogeneous can produce thus in principle, and promptly the production equipment of manufactured materials plate has two fibrillation devices of log, and one is used for broad leaf tree and one and is used for coniferous tree.But so-called " material homogenizer " hypergeometric example on acquisition cost is expensive and therefore investment in production equipment person tend to only to purchase single material homogenizer and only be that one type timber is optimized adjustment generally speaking with it.Tong Shi cost is that the timber processing result aspect of other type is slightly inadequate in this case.The fracture geometry and different baking and drying times of chips when the main distinction between two types of timber is fibrillation.
The development trend of high productive capacity thin plate production has further increased the problem that dissimilar timber brought.This means that thinner plate of material need be with higher speed production.Therefore proposing of task is, utilizes distribution device or cloth stub bar to form one on the moulding band and has the bulk pad that best weight per unit area distributes.Self-evident, minimum or less cloth error unlike being no more than 150mm, preferably plays a decisive role on the maximum bulk cargo height of 10-120mm on 150-500mm or bigger bulk pad height like that.Under thick plate of material situation, therefore the cloth error has also reduced the transverse tensile strength of finished-product material plate as the fluctuation of the weight per unit area on length and width appearance.In thin plate was produced, minimum cloth error will cause inaesthetic visual impact to final products.In this regard, one type clouding importantly appears on the plate surface, itself in addition only when large tracts of land is observed, just can manifest, and 100 * 100 or the test profile of 200 * 200mm on can't see.
At the plate of material maximum ga(u)ge is that the clouding that occurs in the thin material flitch production of 3mm occurs in the following cases, and promptly the bulk cargo of sunburner or caking is long by being arranged on the distribute roll conveying on the cloth stub bar and therefore slowly hanging between roller.But bulk cargo need be removed from process by separator (mostly being greatly and the helical conveyor of producer to horizontal setting) on the end of roller bed usually.On structure, this class process equipment is applicable to the very wide range of work and the plate of material that therefore can process different-thickness and width.Therefore make a concession in the best equipment structure of bulk cargo height 10-1200mm.Subject matter in this respect is the flow of material of cloth when the bulk pad height of 10mm is different from the 1200mm height fully.If but by for producing the thick bulk pad highly reach 1000mm maximum 50 distribute rolls parallel to each other being set, the defective material of so blocked up or bonding is when the thin bulk pad cloth of 150mm at most, arriving separator will be through at least 20 distribute roll.Why this situation occurs, be because since the bulk cargo amount few, bulk cargo set distribute roll first three/once on scatter fully.Because the distribute roll that rotates has the lug boss or the spike-tooth of variable number usually, so original blocked up defective material can or pass through gap landing at random, division or fragmentation also can arrive on the bulk pad then again when perhaps needing.But when broken defective material, the material piece falls by the cloth gap at any time and nearby.If size is directly or still dropped on before being about to transfer on the separator on the bulk pad for homogeneous finished product and original from 1 coin-dividing size to 2 Euro coins for this defective material that mostly is fiber block greatly, it is poor to form weight per unit area so here, and it shows as local deepening or clouding in the final products of making.
Little cloth error will quicken to occur in the feed zone so-called duds (bulk cargo transports to opposite explosion type with producer) on the feed zone of known continuous extruder in addition.This duds causes bulk pad folding in the inlet gap, makes the counter-pressure that occurs depression on the steel band in a large number thereby be folded in suddenly to form in the top clearance under the situation of high extruding force.The surface quality of steel band is also most important to the surface quality of the plate of material that will produce.The stability of steel band also is subjected to the local infringement of hardening fully and hardening, and wherein, depression reparation commonly used can only be undertaken by built-up welding.Therefore, though the surface is smooth again with respect to goods, the material thickening that occurs on the steel band no longer recovers and obviously reduces the service life of steel band in this case.
Usually bulk pad is on the moulding band during direct or indirect cloth, the bulk cargo intermediate storage is handled on width and length like this by different device (material roller, distribution rollers, loose metal roller and this class roller) in a bulk bin and there, makes bulk bin carry out best bulk cargo discharging in time with on the width by falling back of moulding band.Reason local or random density fluctuation is the air-swirl in the materials flow scope on the bulk pad.The professional knows in this regard, generally undertaken by the material roller that makes the bulk cargo acceleration from the discharge of bulk bin.According to device structure, even limit loose metal roller can also be set in the blanking chute, so that bulk cargo the best is scattered.By the high-speed rotation of the hundreds of commentaries on classics of loose metal roller per minute, in the bulk cargo that falls, produce whole air-swirl, it is distributed in maximum one meter whereabouts bulk cargo stream scopes substantially.If bulk cargo directly is scattered on the moulding band through distribute roll below feed zone or blanking chute, then can go wrong, because scrambling occurred and air-swirl can directly pass.Therefore occur local material mound and material paddy on bulk pad, they are in the scrambling that shows as owing to the weight per unit area difference on the plate of material of making on (on the thin plate) cloud form variable color or (on thin plate and the slab) load property or the horizontal pull resistance.
Be generally in the prior art on the equipment and technology and adjust cloth height (distance of roller blanket and moulding band), the vertical roller blanket of adjusting under the bulk pad differing heights situation of want cloth.In this case, also must add and adjust the part of appliance that is arranged on the roller blanket simultaneously, thereby cause to increase the huge spending on the equipment and technology, so that can cloth stub bar, bulk bin be set vertically on equipment with adjusting and lead to the bulk cargo conveying device of bulk bin when needing.The simple vertical adjustment of moulding band is also impracticable generally speaking, because the bulk pad of a cloth is quick on the draw and suffers damage the moulding band of non-linear operation or the bulk pad of internal modification causes quality to descend.
Summary of the invention
The object of the present invention is to provide a kind of method, utilize this method that the production of plate of material is being optimized aspect surface quality and the plate characteristic, method is that the cloth of bulk pad was optimized aspect its uniformity before compacting and the fines of bulk cargo part is added in the bulk pad equably.A kind of affiliated forming station that is used to implement this method is provided in addition, and it can also be under the situation of minimum equipment and technology spending except above-mentioned advantage, and the bulk pad of differing heights is carried out best cloth.
This purpose utilizes the described method of claim 1 to be achieved thus according to the present invention, it is bulk cargo at first hits roller blanket length 1-4m after discharging from bulk bin homocline district, wherein, the homocline district does not have tangible cloth effect and transports bulk cargo and bulk cargo is transferred to the cloth district of roller blanket subsequently, and there with the distribution of lengths of 0.5-8m on the moulding band.
Solution according to forming station, for forming two different zones of roller blanket different equal material roller and the distribute rolls that constitute are set, wherein, on the carriage direction of roller blanket, all material roller be arranged in the homocline district by the length of 1-4m and subsequently distribute roll be arranged in the cloth district by the length of 0.5-8m.
Utilize according to the cloth performance of structure of the present invention so successfully to be optimized, make the cloth stub bar that best cloth result all can be provided when making any bulk pad height the cloth stub bar.The moulding of bulk pad has sufficiently high quality when being included in thin plate production in addition on its density and uniformity thereof, and the composite wood boards that make does not have defective or variable color.The pad of avoiding in addition causing owing to duds in the feed zone folds dangerous.This point is specially adapted to make fiberboard, for example the MDF plate.When making fiberboard, not only use length to reach the fiber of 3mm, but also use the quite high fines part of the not enough 0.1mm of fiber granularity.In this regard, a little advantage of use mixing aspect the timber as the basis when the manufactured materials plate is that coniferous tree is compared the fines part that has still less with broad leaf tree with annual plant.In traditional cloth by distribute roll, fines part generally speaking on first distribute roll immediately simultaneously by dropping on the moulding band, thereby very strong inhomogeneities appears on the height at bulk pad aspect the fines part.Advantage provided by the invention is, do not have tangible fines or material to drop on the moulding band and the fines part is retained in during transporting on the equal material roller and is mixed in the bulk cargo by the homocline section.From distribute roll, bulk cargo begins to fall equably on the moulding band, and wherein, the fines part appears on the height of bulk pad equably.Therefore principle of the present invention is, in the cloth district, distribute roll has a spot of spike-tooth or lug boss and has bigger each other spacing simultaneously, so that can be by short cloth section uniform distribution and do not continue to avoid the cloth bulk cargo classification except excessive bulk cargo best.
Another advantage of a kind of preferred implementation of forming station is that for making higher bulk pad, the roller blanket can be with respect to the moulding band by angle adjustment.In this regard, the roller blanket preferably promotes on the end in cloth district like this, makes it under the higher bulk pad situation of want cloth, all the time with the cloth Height Adjustment optimal spacing about 200mm, wherein, the cloth height is meant the root edge of distribute roll and the distance on the pad surface that has formed here.Because produce the linear flow of bulk cargo, upwards also produce a kind of linear bulk pad that rises at producer by the cloth district.
Reduced the equipment and technology spending in this regard because the roller blanket can by angle and the part can be vertical adjustment simply carry out the adjustment of cloth height in the cloth district.
Principle of the present invention in this regard is apparent, because the conduct in by angle adjustment roller blanket of homocline district is used to eliminate the conveying device (measuring to first distribute roll from the first equal material roller) of difference in height to scatter high bulk pad, and therefore use at the same time and strengthen spacing between the distribute roll and use distribute roll originally to reduce under the situation of spike-tooth quantity on one's body, can make the cloth height in the cloth district obtain best the adjustment.Because by the whole cloth amount that improves each long measure, the super mean value of the bulk pad ground surge of the cloth of.Avoid by the unsuitable classification of distribute roll (on first distribute roll, improve the fines part, reduce the coarse fodder part) by improving the cloth amount of each long measure of moulding band, adding, and can high-quality mode on apparatus for distributing, make high and low bulk pad.In this regard, it is not to pass through distribute roll simultaneously that important also being directly do not hit distribute roll and air-swirl from the bulk cargo that bulk bin falls, but at first hits conveying roller or equal material roller.Bulk cargo scatters with high flow capacity subsequently, wherein, except defectiveness or excessive bulk cargo, can not occur classification between these indivedual bulk cargos.In the zone of scattering, effectively avoid distribute roll interference air-swirl up and down.The air-swirl that passes equal material roller or distribute roll on moulding band direction makes weight per unit area distribution variation and causes fines in addition and long fiber separation.
Compare with the prior art that adopts unified distribute roll and the present invention be advantageous in that, mainly when making the bulk pad cloth of thin material flitch, all expansion is carried out in the fiber materials flow on the material roller from below.The fiber materials flow is shifted in the cloth district thus, and it upwards can be called aspect the weight per unit area uniformly at producer.Therefore weight per unit area distribute horizontal and vertical and short interval measurement on thin plate be improved significantly and avoided the cloud form plate surface of final products.Bulk cargo carries out expansion and constantly moves up and down above by equal material roller and carry out from below in the homocline district, wherein, upwards observe at producer, and the bulk cargo area distribution of crossing multifilament is in the adjacent area of less fiber.Upward make the crest diffusion also therefore near optimal proportion at crest (crossing the zone of multifilament) by approximate shaking.
