Description
Technical field
The present invention relates to a kind of method that is used for forming by bulk cargo bulk pad in the process of making composite wood boards; Promptly; Be used in the process of making composite wood boards; From bulk cargo, form bulk pad by pressure on the extruder and heat, wherein, bulk cargo is made up of wood-fibred, wood chip or this type particle.The present invention relates to a kind of forming station that is used for being formed by bulk cargo on formed strip in the process of making composite wood boards bulk pad in addition.
Background technology
With dispersible made plate of material 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 be by pressure and continuous perhaps discontinuous the carrying out of heat.The OSB plate that the MDF plate that the common materials plate of making in this case is made up of medium density fiber generally speaking perhaps is made up of the wood chip or the chips of directed cloth.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 formed strip by stock guide, perhaps through 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 formed strip through distribute roll, also must from production process, remove until remaining inapplicable bulk cargo.Two kinds of principles prove effective and the application of succeeding with producing conditionally producing slab in the thin plate.
Produce in the evolution in recent years in plate of material, the trend of mixing timber occurs 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 Wood Processing concentrates on the mixed forest, thus the equipment that will build no matter be 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 also expensive so investment in production equipment person tends to only purchase single material homogenizer and generally speaking its timber that is merely one type is optimized adjustment.Simultaneously cost is that the aspect is slightly inadequate as a result for the Wood Processing of other type 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 to utilize distribution device or cloth stub bar on formed strip, to form one and have the bulk pad that best weight per unit area distributes.Self-evident, unlike being no more than 150mm, preferably that kind plays a decisive role minimum or less cloth error on the maximum bulk cargo height of 10-120mm on the perhaps bigger bulk pad height of 150-500mm.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 on the test profile of 100x100 or 200x200mm, 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 under following situation, and promptly the bulk cargo of sunburner or caking is long through being arranged on the distribute roll conveying on the cloth stub bar and therefore between roller, slowly hanging.But bulk cargo need be removed from process by separator (being and the helical conveyor of producer to horizontal setting mostly) on the end of roller bed usually.Say that from structure this type 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 through for producing the thick bulk pad highly reach 1000mm maximum 50 parallel distribute rolls 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 of rotation has the lug boss or the spike-tooth of variable number usually, so blocked up originally defective material can be perhaps 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 through the cloth gap at any time and nearby.If size is directly or before being about to transfer on the separator, still drop on on finished product and the bulk pad original homogeneous from 1 coin-dividing size to 2 Euro coins for this defective material of fiber block mostly; It is poor to form weight per unit area so here, and it shows as local deepening or clouding in the final products of processing.
Little cloth error will quicken to occur in the feed zone so-called duds (bulk cargo transports with production explosion type in the opposite direction) 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 under the situation of high extruding force, be folded in suddenly to form in the top clearance.The surface quality of steel band to the surface quality of the plate of material that will produce also most important.The stability of steel band also receives 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 formed strip directly or indirectly during cloth; The bulk cargo intermediate storage is handled on width and length by different device (material roller, distribution rollers, loose metal roller and this type roller) in a bulk bin and there like this, makes bulk bin carry out best bulk cargo discharging in time with on the width through falling back of formed strip.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 carries out through 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 before hitting the roller blanket, bulk cargo the best is scattered.Through 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 basically.If bulk cargo directly is scattered on the formed strip through distribute roll below feed zone or blanking chute, then can go wrong, because scrambling occurred and air-swirl can directly pass.Therefore local material mound and material paddy on bulk pad, occur, they are showing as the perhaps scrambling on (on thin plate and the slab) load property or the horizontal pull resistance of (on the thin plate) cloud form variable color owing to the weight per unit area difference on the plate of material of processing.
Be generally adjustment cloth height (distance of roller blanket and formed strip) on the equipment and technology in the prior art, vertical adjustment roller blanket under the bulk pad differing heights situation of want cloth.In this case; Also must adding simultaneously, adjustment is arranged on the part of appliance on the roller blanket; 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 transport of bulk bin when needing.The adjustment of the simple vertical of formed strip is also impracticable generally speaking, because the formed strip of non-linear operation is quick on the draw and suffers damage the bulk pad of a cloth 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 was achieved by the method that bulk cargo forms bulk pad in the process of making composite wood boards according to of the present invention being used for; Wherein, Bulk cargo is made up of wood-fibred or wood chip, wherein, utilizes discharge device that bulk cargo is quantitatively entered in the blanking chute from bulk bin (13); Bulk cargo at first hits the homocline district of roller blanket length 1-4m after discharging from bulk bin; Wherein, the homocline district that is provided with equal material roller does not have tangible cloth effect and transports bulk cargo and bulk cargo is transferred to the cloth district that is provided with distribute roll of roller blanket subsequently, and there with the distribution of lengths of 0.5-8m on formed strip.
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.Be included in the moulding of thin plate bulk pad when producing in addition, on its density and uniformity thereof, have sufficiently high quality, the composite wood boards that will make do 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.A little advantage of when the manufactured materials plate, use mixing aspect the timber as the basis in this regard, 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 through dropping on the formed strip, 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 formed strip during transporting, to be retained on the equal material roller with the fines part to be mixed in the bulk cargo through the homocline section.From distribute roll, bulk cargo begins to fall equably on the formed strip, 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 through 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 formed strip 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 through 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 obvious; Because the homocline district transport (measuring to first distribute roll from the first equal material roller) that conduct is used to eliminate difference in height in by angle adjustment roller blanket is 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 adjustment.Because through the whole cloth amount that improves each long measure, the ultra mean value of the bulk pad ground surge of the cloth of.Avoid through the unsuitable classification of distribute roll (on first distribute roll, improve the fines part, reduce the coarse fodder part) through improving the cloth amount of each long measure of formed strip, 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 on the formed strip direction, passes equal material roller or distribute roll 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 through 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) through approximate shaking.
