Kwinkqubo yoshishino lokwenza amaphepha oluguqukayo luye kwisantya esiphezulu nokuphucula, icandelo lokomisa, njengekhonkco eliphambili elichaza umgangatho wephepha kunye nokusebenza kakuhle kwemveliso, alikaze liyeke ukuhlaziya itekhnoloji yezixhobo zalo. Nangona iisilinda zokomisa ngomphunga zemveli zinokuhlangabezana neemfuno ezisisiseko zokomisa, zinengxaki efana nokuphaphazela kwephepha, ukushwabana, kunye nokuqhekeka kweemeko zemveliso ekhawulezayo, okwenza kube nzima ukuziqhelanisa neemfuno zemveliso yeemveliso zephepha ezinobungakanani obuphantsi kunye nezikumgangatho ophezulu. Ngokuchasene nale mvelaphi, kuye kwavela iiroli zokomisa ze-VAC (ezaziwa ngokuba ziiroli zeVac, oko kukuthi, iiroli zokomisa nge-vacuum) . Ngemisebenzi yazo ekhethekileyo yokufunxa nge-vacuum kunye nemisebenzi yokuncedisa ukomisa, ziye zaba zizixhobo ezixhasayo kwicandelo lokomisa loomatshini bephepha abakhawulezayo, zibonelela ngenkxaso ebalulekileyo yokuphucula umgangatho kunye nokusebenza kakuhle kushishino lokwenza amaphepha.

Iiroli zokomisa ze-VAC azizozinto zemveli zokufudumeza nokomisa, kodwa zizixhobo zokuzinzisa iwebhu yephepha ezikhawulezayo nezokuncedisa ukomisa ezisebenza ngokubambisana neesilinda zokomisa ngomphunga. Zisetyenziswa kakhulu kulungiselelo lokomisa olunentambo enye koomatshini bephepha abakhawulezayo, kwaye zihlala zifumaneka kwimigca yemveliso yephepha lenkcubeko, iphepha eligqunywe ngengubo, ikhadibhodi emhlophe, kunye nephepha elisisiseko elinokomisa kancinci. Ngokungafaniyo nendlela yokusebenza yeesilinda zokomisa ngomphunga zemveli ezixhomekeke kubonelelo lwangaphakathi lomphunga ukubonelela ngobushushu bokomisa, iiroli zokomisa ze-VAC zifumana uzinzo lwewebhu yephepha ngokufunxa uxinzelelo olubi, kwaye kwangaxeshanye zinceda ekukhawuleziseni ukukhutshwa komoya omanzi, ngokuphucula ngokungathanga ngqo ukusebenza kakuhle kokomisa ngokubanzi, zenze inkqubo yokomisa edibeneyo "yokuzinzisa iwebhu yokufudumeza + iphepha".

Ngokuphathelele uyilo lwesakhiwo, imiqulu yokomisa ye-VAC yahlulwe kakhulu yaba ziintlobo ezimbini ukuze ivumelane nesantya semoto esahlukileyo kunye neemfuno zemveliso. Phakathi kwazo, i-groved Vac roll ayifuni ibhokisi yokucoca eyakhelwe ngaphakathi. Umphezulu we-roll unikwe imiqulu enobubanzi obuyi-5mm kunye nobunzulu obuyi-4mm, kwaye imingxunya emincinci isasazwa ezantsi kwemiqulu, kunye nemingxunya exineneyo emaphethelweni ukuze kube lula ukufaka imisonto. Ingavelisa i-vacuum degree emalunga ne-2kPa xa ihambelana nebhokisi yomoya evuthelayo, kwaye izinga lokuvula lilawulwa kwi-0.1% ~ 0.4%, ifezekisa ukubopha kwewebhu yephepha ngokusebenzisa uxinzelelo olubi lokuhamba komoya. Ulwakhiwo lwayo lulula, lufanelekile kwimveliso yomatshini wephepha ophakathi nowesantya esiphezulu. Olunye uhlobo yi-vacuum box type Vac roll eyakhelwe ngaphakathi, exhotyiswe ngemingxuma echanekileyo okanye imingxunya exineneyo kwiqokobhe le-roll, kunye negumbi lokucoca elinokulungiswa ngokwebubanzi obungaphakathi, eliqhagamshelwe ngqo kwipompo ye-vacuum. Ine-vacuum degree ephezulu kunye nolawulo oluchanekileyo, eyenzelwe ngokukodwa oomatshini bephepha abakhawulezayo kakhulu abanesantya esingaphezulu kwe-1000m/min, abanokujongana ngempumelelo nengxaki yokuzinzisa iwebhu yephepha phantsi kweemeko zokusebenza ezinzima. Kwezinye iindlela zemveliso eziphezulu, ii-Vac rolls kunye nee-dryer cylinders zenza umlinganiselo ochanekileyo. Umzekelo, umatshini wephepha oprintayo okumgangatho ophezulu onomphumo wonyaka weetoni ezili-130,000 unecandelo lokomisa elenziwe zii-cylinders zokomisa ngomphunga ezingama-29 kunye nee-Vac rolls ezininzi ezinobubanzi be-1500mm. Umqolo ongezantsi wee-dryer cylinders zemveli uthatyathelwa indawo ngokupheleleyo yi-Vac rolls, nto leyo eyenza imveliso eqhubekayo iphumelele ngaphandle kokufaka imisonto kwaye iphucula kakhulu uzinzo lokusebenza.

Ixabiso eliphambili le-VAC dryer rolls livela kumgaqo-nkqubo wazo wesayensi kunye neenzuzo zokusebenza phantsi kweemeko zokusebenza ezikhawulezayo. Kwimveliso yokwenyani, umqolo ophezulu weesilinda zokomisa ngomphunga unoxanduva lokubonelela ngobushushu bokunyibilikisa umswakama kwiwebhu yephepha, ngelixa umqolo ongezantsi we-VAC dryer rolls ufunxa ngokuqinileyo iwebhu yephepha kumphezulu wocingo olomileyo ngoxinzelelo olubi, ukuphelisa ngempumelelo amandla e-centrifugal aveliswa kukusebenza okukhawulezayo, kwaye ngokusisiseko usombulula iindawo ezibuhlungu zoshishino ezifana nokuphaphazela komphetho wewebhu yephepha, ukushwabana, nokuqhekeka. Kwangaxeshanye, ukuhamba komoya kwipokotho yomoya kutsalwa kwimingxunya yeroli, kukhawulezise ukukhutshwa komoya omanzi, kuphule umaleko wokugcina umoya omanzi kumphezulu wewebhu yephepha, kwaye kuphucule ngokungathanga ngqo izinga lokomisa. Kwinqanaba lokufaka intambo, uyilo lwemingxunya exineneyo emaphethelweni lunokuphucula isiphumo sokufunxa, luphucule kakhulu izinga lempumelelo yokufaka intambo, kwaye lufinyeze ixesha lokufaka intambo. Ityala lotshintsho lomatshini wephepha we-PM15 kaLee & Man Paper liqinisekisa ngokupheleleyo oku. Emva kokuguqula ii-cylinders zokuqala ezixhonywe kabini zibe zii-cylinders zokomisa ezine-single-hung kwaye ziphuculwe zibe yi-Vac rolls, zidibene neebhokisi ezizinzileyo ezilungisiweyo kunye nezixhobo zokungenisa umoya ezipokothweni, izinga lokuqhekeka kwewebhu yephepha lancitshiswa ngama-60%, ixesha lokungasebenzi elingacwangciswanga lancitshiswa ngama-30%, kwaye xa kuveliswa iphepha elisisiseko le-corrugating paper elingama-70~90g/m² ngesantya se-1000m/min, ukuqhekeka kwephepha eliqhelekileyo ngenyanga kwakuphindwe kalishumi kuphela, kwaye ukusebenza kakuhle kwemveliso kwandiswe nge-3%.

Xa kuthelekiswa neesilinda zemveli zokomisa ngomphunga, indlela esebenza ngayo imiqulu yokomisa nge-VAC ithambekele ekuzinziseni iwebhu yephepha kunye nokomisa ngokuncedisa, kwaye ezi zimbini zakha ubudlelwane obuhambelanayo nobudibeneyo. Ngokuphathelele unikezelo lomthombo wobushushu, imiqulu yokomisa nge-VAC ayinasakhiwo sokufudumeza esakhelwe ngaphakathi kwaye ixhomekeke ngokupheleleyo kuxinzelelo olubi ekusebenzeni, ngelixa izilinda zokomisa ngomphunga zisebenzisa umphunga njengomthombo wobushushu kwaye zenza imisebenzi ephambili yokudlulisa ubushushu kunye nokomisa; ngokwesakhiwo somphezulu, imiqulu yokomisa nge-VAC isebenzisa uyilo olunemiqolo okanye olugobileyo, ngelixa izilinda zokomisa ngomphunga uninzi lwazo zinomphezulu wesinyithi ogudileyo ogqunywe nge-chrome okanye otyhidiweyo; ngokwendlela yokusebenza, imiqulu yokomisa nge-VAC igxila ekuzinziseni ububanzi bewebhu yephepha, ukukhupha umswakama ngokuncedisa, kunye nokunciphisa iziphene zephepha, ngelixa izilinda zokomisa ngomphunga zigxila ekudluliseleni kobushushu okusebenzayo ukuze kugqitywe ukufuma okuphambili kwiwebhu yephepha. Ngokuphathelele amandla okomisa, amandla okomisa eroli yokomisa yeroli yokomisa ye-VAC enye anqongophele, kwaye malunga ne-2 ~ 3 imiqulu yeVac ilingana nesilinda enye yokomisa eqhelekileyo. Ngoko ke, kwiindlela ezisebenzayo, kuyimfuneko ukuthelekisa ngokwesayensi inani lee-Vac rolls kunye nee-steam dryer cylinders ngokwesantya sesithuthi kunye nobungakanani bephepha ukuze kufezekiswe ulungelelwaniso phakathi kokusebenza kakuhle kunye neendleko.

Phantsi kwemvelaphi yokuqhubela phambili kwesicwangciso "sekhabhoni ephindwe kabini" kunye notshintsho olukrelekrele nolonga amandla kwishishini lokwenza amaphepha, ukusetyenziswa kweeroli zokomisa ze-VAC kufuneka kuthathele ingqalelo ulawulo lokusetyenziswa kwamandla kunye nokulungiswa kokugcinwa. Iiroli zokomisa ze-VAC zifuna ukuxhasa iinkqubo zokomisa kunye nokungenisa umoya, kwaye xa kuthelekiswa neendlela zokomisa zendabuko, iindleko zazo zokusetyenziswa kwamandla kunye nokugcinwa ziphezulu kancinci, kodwa ukonga amandla kunye nokunciphisa ukusetyenziswa kunokufezekiswa ngokulungiswa kobuchwephesha. Umzekelo, iLee & Man Paper iphucule ibhokisi yokomisa yeSymRun ngexesha lokuguqulwa, yanciphisa umthwalo wefeni yokuhambisa umoya ngama-30% ngelixa iphucula inqanaba lokukhupha umoya; iValmet Finland iphucule isithuba phakathi kweeroli zeVac kunye neesilinda zokomisa ngokuskena kunye nokwenza imodeli ye-3D, yonyusa i-engile yokusonga ye-dryer yephepha, yanciphisa inani lee-blower kunye neepayipi zomoya, kwaye yanciphisa ukusetyenziswa kwamandla kunye neendleko zokulungisa. Kulondolozo lwemihla ngemihla, kuyimfuneko ukuhlaziya rhoqo imingxunya kunye nee-grooves zeroli yeVac ngomoya ocinezelweyo ukuthintela ukuvaleka, ukujonga ukusebenza kokuvala i-vacuum kunye nobushushu bebhearing ngaxeshanye, kunye nokulawula inqanaba lokukhupha umoya ngaphakathi kweemfuno zenkqubo. Ukudibanisa neenkqubo zokungenisa umoya ezisetyenziswa epokothweni kunye neepompo zobushushu kunokuphucula kakhulu ukusebenza kakuhle kokomisa kwaye kunciphise ukusetyenziswa komphunga.

Ngokuphuculwa okuqhubekayo kwetekhnoloji yoomatshini bephepha abakhawulezayo kunye nemfuno ekhulayo yeemveliso zephepha eziphezulu, ukuhlaziywa kwetekhnoloji kweeroli zokomisa ze-VAC kuya kuhambela phambili ekuchanekeni, ukugcinwa kwamandla, kunye nobukrelekrele. Kwixesha elizayo, ngoncedo lwetekhnoloji eziphambili ezifana nokulinganisa kwe-CFD kunye nokubala ngamanani, uyilo lomngxuma kunye nesakhiwo segumbi lokucoca i-Vac rolls zinokulungiswa ngakumbi ukuphucula ukuchaneka kokulawula uxinzelelo olubi kunye nenqanaba lokubopha iphepha; kudityaniswe nokuziva okukrelekrele kunye nohlalutyo lwedatha enkulu, ukulawulwa okunamandla kwenqanaba lokucoca i-vacuum kunokufezekiswa ukuze kuhambelane neemfuno zemveliso zeentlobo ezahlukeneyo zephepha kunye nesantya esahlukileyo sezithuthi; kwangaxeshanye, ngokuphucula izinto kunye nokwenza ngcono ulwakhiwo, ukusetyenziswa kwamandla ezixhobo kunye nokuguguleka kunokuncipha, kwaye ubomi benkonzo bunokwandiswa. Njengesixhobo "sokuzinzisa umgangatho" kwiinkqubo zokomisa iphepha ezikhawulezayo, iiroli zokomisa ze-VAC azisombululi kuphela iindawo ezininzi zentlungu zokumiswa kwendabuko phantsi kweemeko zokusebenza ezikhawulezayo, kodwa zikwanceda amashishini okwenza iphepha ukuphucula umgangatho wemveliso kunye nokwenza ngcono ukusebenza kwemveliso, okufaka amandla amatsha kuphuhliso oluphezulu lweshishini lokwenza iphepha.
