Abstract:Lo mbhalo uchaza ngezinzuzo kanye nokubi kwezinhlelo zokulawula ukungezwani kokuvuleka kwendandatho kanye ne-loop evaliwe emishinini elaminethi engancibilikiyo. imikhiqizo ecutshungulwayo yamafektri okupakisha aguquguqukayo ihlukahlukene, izimboni zokupakisha zihlala zidingeka kumikhiqizo enezinto ze-PE ezincanyana noma ezinzile ngosayizi, ngaleso sikhathi, uhlelo lokulawula ukungezwani kwe-loop lungcono kakhulu. Ngenkathi amafektri okupakisha ane azikho izidingo eziphakeme kangaka emikhiqizweni, iyatholakala futhi ukukhetha elula, uhlelo lokulawula ukuvulwa kwendandatho.
1.Ukubaluleka kokulawula ukungezwani kuzinhlanganisela ezingenazo i-solvent
Ngenxa yesisindo esincane samangqamuzana okunamathelayo angenayo i-solvent, cishe awanakho ukunamathela kokuqala, ngakho-ke ukufaniswa kwengcindezi kubalulekile kuzinhlanganisela ezingenazo i-solvent.I-tension ratio ephansi ingabangela izinkinga ezilandelayo:
(1)Ngemuva kokugoqa, isikhumba somqulu siyashwabana futhi kukhona ukwanda kwemfucuza.
(2) Ukugoqa okuqinile kwefilimu eyinhlanganisela ngemva kokwelapha kubangela amaphutha okukhiqiza.
(3) Lapho wenza izikhwama, usebe lokuvalwa kokushisa luyashwabana
2.Izinhlelo ezimbili zokulawula ukungezwani ezisetshenziswa njengamanje emishinini yokugcwalisa i-solvent-free laminating
Isistimu yokulawula ukushuba kwe-loop evulekile: Itheminali yokokufaka ifaka inani le-tension esilimisayo, futhi okokusebenza kulawula i-torque ngokwenani lethiyori elibekwe umenzi ukuze kuqedelwe okukhiphayo kwe-tension.
Isistimu yokulawula ukungezwani kwe-loop evaliwe: Ngokufanayo, inani lokucindezela esilimisayo elokufaka okuvela ekugcineni okokufaka, futhi isilinda esintantayo serola sigcwaliswa ngomoya ocindezelwe.Ukushuba kwesimo efilimini kuyisamba samandla amile we-roller amandla adonsela phansi kanye namandla aqondile esilinda.Lapho ukushuba kushintsha, i-roller entantayo iyashwibeka, futhi inkomba yendawo ibona ushintsho lokuqina, ibuyisele emuva ekugcineni kokufaka, bese ilungisa ukushuba.
3.Izinzuzo kanye nokubi kwezinhlelo ezimbili zokulawula ukungezwani
(1).Open loop tension system
Inzuzo:
Umklamo jikelele wemishini uzoba lula kakhulu, futhi umthamo wemishini ungaphinde ucindezelwe.
Ngenxa yokuthi i-open-loop tension system ilula uma kuqhathaniswa, amathuba okwehluleka ngesikhathi sokusebenza kwesikhathi eside kwemishini aphansi futhi kulula ukuxazulula inkinga.
Ububi:
Ukunemba akuphakeme.Ngenxa yokulawula okuqondile kwe-torque, ukuzinza nokunemba akukuhle kakhulu ngesikhathi sokuguqulwa okuguquguqukayo nokuma, ukusheshisa nokunciphisa, kanye nezinguquko kububanzi bekhoyili, ikakhulukazi uma inani lokucindezela libekwe ukuthi libe lincane, ukulawulwa kokucindezeleka akufanelekile.
Ukuntuleka kokulungiswa okuzenzakalelayo.Uma izimo zangaphandle ezifana ne-substrate film rolls zingajwayelekile, umthelela ekulawuleni ukucindezeleka ubaluleke kakhulu.
(2)Isistimu yokulawula ukungezwani kweluphu evaliwe
Inzuzo:
Ukunemba ngokuvamile kuphezulu.Umthelela wokuguqulwa okuguquguqukayo nokuma okumile, ukusheshisa nokwehla, kanye noshintsho kububanzi bekhoyili ekulawuleni ukushuba mancane, futhi ukungezwani okuncane ngisho nokuncane kungalawuleka kahle.
