Description

Izum se odnosi na postupak strujno dinamičke proizvodnje vlaknastih hasura promjenjivog oblika, visoke čvrstoće trganja iz vlaknastog runa, koje se sastoji i, sa veznim sredstvom impregniranih vlakana celuloze i termoplastičnih vlakana i/ili prirodnih vlakana biljnog porijekla pri čemu se grumen od vlaknastog runa miješa u bačvastom spremniku i iz te mješavine se formira vlaknasto runo, koje se sa igličastim strojem učvršćuje u vlaknastu hasuru. Izum se odnosi dalje na primjeru ovim postupkom proizvedene hasure kao i postrojenja za provedbu ovoga postupka. The invention relates to the process of the current-dynamic production of variable-shaped, high-tear strength fibrous mats from fibrous fleece, which consists of, with a binding agent, impregnated cellulose fibers and thermoplastic fibers and/or natural fibers of plant origin, whereby a nugget of fibrous fleece is mixed in into a barrel container and from this mixture a fiber fleece is formed, which is fixed into a fiber fleece with a needle machine. The invention further relates to the example of the hasura produced by this process, as well as the plant for implementing this process.

Postupak spomenute vrste poznat je iz AT-PS 387.798. Prema prednostima ovog poznatog postupka miješa se vlaknasto runo u bačvastom spremniku i iz te mješavine stvaraju se npr. sljedeća runa na jednom bubnju za polaganje runa. kod toga se pokazalo, da transport razvlaknjene vlaknaste mase proizlazi besciljno od valjka bačvastog spremnika od bubnja za polaganje runa, pri čemu dolazi do nepravilnosti vlaknastog grumena na bubnju za polaganje runa kao što su nepravilno raspoređivanje površinske težine po širini vlaknastog runa. Dalje se kod toga uočava, da kod drvenih vlakana impregniranih sa umjetnom smolama uglavnom dolazi radi njihove velike težine do nalijeganja donje strane runa koje se polaže, dok se istovremeno termoplastična i/ili neimpregnirana prirodna vlakna biljnog porijekla raspoređuju u gornjim slojevima runa koje se polaže. Ova različita slojevitost vodi s time do problema kod daljnje obrade ovih hasura, budući da je donja strana hasura radi njenog previsokog dijela veznih sredstava ljepljiva, dok gornja strana gotovo uopće nije zalijepljena. The procedure of the mentioned type is known from AT-PS 387.798. According to the advantages of this known procedure, the fibrous fleece is mixed in a barrel container and from this mixture, for example, the next fleece is created on one fleece laying drum. in this case, it was shown that the transport of the fiberized fibrous mass results aimlessly from the roller of the barrel container to the drum for laying the fleece, whereby irregularities of the fibrous lump on the drum for laying the fleece occur, such as irregular distribution of the surface weight across the width of the fibrous fleece. Furthermore, it can be observed that with wooden fibers impregnated with artificial resin, due to their heavy weight, the lower side of the fleece that is being laid is pressed against, while at the same time thermoplastic and/or non-impregnated natural fibers of vegetable origin are distributed in the upper layers of the fleece that is being laid. This different layering leads to problems in the further processing of these hashes, since the lower side of the hashes is sticky due to its too high part of the bonding agents, while the upper side is almost not glued at all.

Postavljeni zadatak u ovom izumu se sastoji međutim od toga, da jedna hasura promjenjivog oblika visoke čvrstoće trganja treba posjedovati ravnomjernu težinsku raspoređenost po njenoj širini kao i po njenim slojevima, koja se sastoji iz ravnomjerno izmiješanih vlakana impregnirane i neimpregnirane vrste. The task set in this invention consists, however, in the fact that one hasur of variable shape with high tear strength should have an even weight distribution across its width as well as across its layers, which consists of evenly mixed fibers of impregnated and non-impregnated type.

Ovaj zadatak se rješava postupkom prema izumu na taj način, da se runski grume 2,2’ dovodi bačvastom spremniku 6,6’ u kojem se grumen od vlaknastog runa razvlakni i da se na taj način nastala vlaknasta masa 14,14’ miješa strujom zraka čiji profil nastrujavanja se uspostavlja kroz jedan zračni kanal 10,10’ i u njemu primijenjene elemente za regulaciju 25, 26 kao i preko jedne u smjeru strujanja priključene venturi poluge 7,7’, pri čemu se stvara runo 18,18’ sa jednim ravnomjernim rasporedom površinske težine, koja se nakon izvršenog igličanja dovodi tlačnoj napravi 21,21’ pri čemu se proizvode hasure promjenjivog oblika i visoke čvrstoće trganja 23,23’. This task is solved by the process according to the invention in such a way that the runic lumps 2.2' are fed to the barrel-shaped tank 6.6' in which the lump from the fiber fleece is split and the resulting fibrous mass 14.14' is mixed with an air stream the flow profile of which is established through an air channel 10,10' and the regulation elements 25, 26 applied in it, as well as through a venturi lever 7,7' connected in the direction of flow, whereby a fleece 18,18' is created with an even distribution of surface weight, which, after needling, is fed to the pressure device 21.21', whereupon hasurs of variable shape and high tear strength 23.23' are produced.

Postupa u svezi sa izumom je nadalje naznačen time, da se elementi za regulaciju sastoje iz više, preko širine zračnog kanala 10 raspoređenih klapni 25 i iz više prema zračnoj struji konveksno zakrivljenih dijelova za regulaciju 26 čija se zaobljenost može namještati. The procedure related to the invention is further characterized by the fact that the regulation elements consist of several flaps 25 arranged across the width of the air channel 10 and several regulation parts 26 curved convexly towards the air flow, the roundness of which can be adjusted.

Izum se odnosi nadalje na prednosti primjene hasure proizvedenih prema izumu, koje je naznačeno time, da se primjenjuju jedna ili više hasura 23,23’ primjenjuju za proizvodnju određenih oblika prešanjem pod povišenim tlakom i temperaturom. The invention further relates to the advantages of using the hasures produced according to the invention, which is indicated by the fact that one or more hasures 23, 23' are used for the production of certain shapes by pressing under elevated pressure and temperature.

Izum se odnosi također na jedno postrojenje sa prednostima za strujno dinamičku proizvodnju hasura promjenjivog oblika i visoke čvrstoće trganja iz vlaknastog runa, koje se sastoji iz, sa vezivnim sredstvom impregniranih celuloznih vlakana i termoplastičnih vlakana i/ili prirodnih vlakana biljnog porijekla, koje je naznačeno time, da se postrojenje sastoji, prema protoku materijala jedan a drugim poredanih od stroja za polaganje runa 1, para valjaka za prešanje 3, 4, para valjaka za uvlačenje 5, bačvastog spremnika 6, zračnog kanala 10, koji se napaja ventilatorima 12 i u kojemu su pridodani jedan ili više dijelova za regulaciju 25 u obliku jedne ili više klapni za regulaciju, venturi poluge 7, difuzora 13, bubnja za polaganje runa 15, valjaka za transport 16, 17, mjerne naprave za izmjeru površinske težine 19, igličastog stroja 20, preše 21, stroja za rezanje 22, i naprave za odlaganje 24. The invention also relates to a plant with advantages for the current-dynamic production of hasur of variable shape and high tear strength from fiber fleece, which consists of cellulose fibers impregnated with a binding agent and thermoplastic fibers and/or natural fibers of plant origin, which is indicated by , that the plant consists, according to the material flow, arranged one after the other from the fleece laying machine 1, a pair of pressing rollers 3, 4, a pair of feeding rollers 5, a barrel tank 6, an air channel 10, which is fed by fans 12 and in which added one or more regulation parts 25 in the form of one or more regulation flaps, venturi lever 7, diffuser 13, fleece laying drum 15, transport rollers 16, 17, surface weight measuring device 19, needle machine 20, press 21, the cutting machine 22, and the disposal device 24.

Figures 3 and 4 show in perspective the principle view of the venturi lever with the schematic flow of the air stream placed as a part for regulation in the process.

Strojem za proizvodnju runa (1,1’) se iz jedne smjese koja se sastoji iz npr. sa veznim tkivom poput duroplasta, termoplasta ili elastomera ili mješavina iz toga impregniranih i nakon toga osušenih vlakana celuloze, i termoplastičnih vlakana npr. poliester-, poliolefin-, poliamid-, poliakril- EVA- i/ili prirodna vlakna kao lanena-, kudeljina- i celulozna vlakna, stvara runski grumen (2,2’). Ovaj se nadalje zgušnjava preko valjaka za prešanje (3,3’, 3,3’) i s pomoću jednog para valjaka za uvlačenje (5,5’), se dovodi bačvastom spremniku (6,6’), čije površina je obložena sa iglama ili reznim zupčanicima koji razvlaknjuju runasti grumen. Prema broju preko iste osovine zagonjenih ventilatora 12,12’ se u kanalu zrak 10,10’ stvara zračna struja, čija brzina strujanja se uspostavlja kroz više raspoređenih dijelova za regulaciju 25, 26 (vidi sliku 2) preko širine kanala za zrak u obliku klapni za namještanje. Dijelovi za regulaciju 25 (vidi sliku 1) su prema struji zraka konveksno zakrivljeni i njihova se zakrivljenost može namještati. The fleece production machine (1,1') is made from a single mixture consisting of, for example, with a connective tissue such as duroplast, thermoplastic or elastomer or a mixture of cellulose fibers impregnated and then dried, and thermoplastic fibers, e.g. polyester, polyolefin -, polyamide-, polyacrylic- EVA- and/or natural fibers such as linen-, tow- and cellulose fibers, creates a runic nugget (2,2'). This is further thickened via pressing rollers (3.3', 3.3') and with the help of a pair of feeding rollers (5.5'), it is fed to a barrel-shaped container (6.6'), the surface of which is coated with needles. or with cutting gears that split the woolly nugget. According to the number, over the same shaft of the threaded fans 12,12', an air stream is created in the air channel 10,10', the flow speed of which is established through several arranged regulation parts 25, 26 (see figure 2) across the width of the air channel in the form of flaps for setting up. The parts for regulation 25 (see figure 1) are convexly curved according to the air stream and their curvature can be adjusted.

Miješanje vlakana u struji zraka je nadalje ovisno o brzini strujanja. Ovo miješanje se pojačava zakretanjem venturi poluge 7,7’ za približno + 30° oko njene osi, koja po njenoj širini ukazuje varirajuće prepreke 8,8’. U međuprostorima 9,9’ (vidi sliku 3 i 4) između prepreka 8,8’ povećava se prema veličini međuprostora brzina strujanja smjese zrak-vlakna, čime slijedi dodatno miješanje vlakana u priključenom difuzoru 13,13’. Nadalje takova brzina strujanja proizvodi jedan učinak lopatica koji omogućuje pravilno rasprostranjivanje runa vlakana 14,14’ na bubanj za proizvodnju runa 15,15’. Na takav način novostvoreno runo 18,18’ se dovodi preko valjaka za transport 16,16’ i 17,17’ napravi za mjerenje površinske težine 19,19’. Ove izmjere ukazuju na pravilnu raspodjelu površinske težine kao i rezultat mjerenja, koji se može potiči poznatim postupkom stvaranja runa. Bude li usprkos toga raspored površinske težine nedovoljno dobar, moguće ga je promjenom brzine strujanja namještanjem jednog ili više dijelova za regulaciju 25, 26 promijeniti. Nadalje je preko mogućnosti namještanja venturi poluge 7,7’ dana daljnja mogućnost optimiranja strujnih odnosa. The mixing of fibers in the air flow is further dependent on the speed of the flow. This mixing is enhanced by rotating the venturi lever 7.7' by approximately + 30° about its axis, which indicates varying obstacles 8.8' across its width. In the interspaces 9.9' (see figure 3 and 4) between the obstacles 8.8', the flow rate of the air-fiber mixture increases according to the size of the interspace, which results in additional mixing of the fibers in the connected diffuser 13.13'. Furthermore, such a flow rate produces a paddle effect that enables proper spreading of the fiber webs 14,14' onto the web production drum 15,15'. In this way, the newly created fleece 18.18' is brought over the transport rollers 16.16' and 17.17' to the device for measuring surface weight 19.19'. These measurements indicate the correct distribution of the surface weight as well as the measurement result, which can be induced by the known process of fleece creation. If, despite this, the distribution of the surface weight is not good enough, it is possible to change it by changing the speed of the flow by adjusting one or more parts for regulation 25, 26. Furthermore, through the possibility of adjusting the venturi lever 7.7', there is a further possibility of optimizing the current relations.

U igličastoj mašini 20,20’ koja slijedi u aparaturi, isprepleće se runo 18,18’ sa jednim drugim runom 27,27’, npr. koje se sastoji iz poliester-, poliamid-, staklasta vlakna ili jute, čime se stvara jedna hasura 28,28’ dovoljno dobrog promjenjivog oblika. Da bi se postigla još bolja promjenjivost oblika ove hasure kod daljnje prerade u prešama za formiranje, ona se vodi kroz napravu za prešanje 21,21’, koja može biti npr. roljača ili trakasta preša. Između valjaka roljače se predzgušnjava hasura na temperaturi od 25°C do 150°C i specifičnom tlaku od 5 do 50 kp/cm2 pri čemu se drvena vlakna impregnirana sa umjetnim smolama još jače vežu na dodatna vlakna. Na taj način može hasura kod daljnje obrade npr. kod prešanja u forme preuzeti još veće vlačne sile i stoga je manje podložna stvaranju riseva. In the needle machine 20, 20' which follows in the apparatus, the fleece 18, 18' is interwoven with another fleece 27, 27', e.g. consisting of polyester-, polyamide-, glass fibers or jute, which creates a single pattern 28.28' good enough variable shape. In order to achieve even better variability of the shape of this hasura during further processing in forming presses, it is guided through a pressing device 21,21', which can be, for example, a roller or belt press. Between the rollers of the roller, the wood pulp is pre-densified at a temperature of 25°C to 150°C and a specific pressure of 5 to 50 kp/cm2, whereby the wood fibers impregnated with artificial resins are even more strongly attached to the additional fibers. In this way, during further processing, for example, when pressing into forms, the hasur can take on even greater tensile forces and is therefore less susceptible to the formation of rips.

Dodatno se pretzgušnjena hasura 24,24’ odlaže nakon prolaza stroja za rezanje 22,22’ na napravu za odlaganje 23,23’. Additionally, the pre-thickened waste 24.24' is deposited after the passage of the cutting machine 22.22' on the disposal device 23.23'.
