Ngokuthuthuka nenqubekelaphambili yemishini yokupakisha, ukusetshenziswa kwemishini yokupakisha okuzenzakalelayo kuvame kakhulu, ikakhulukazi kumshini wokuwasha, izimonyo, ukudla, imithi kanye nezinye izimboni.I-Henkel China Detergent ingomunye wabakhiqizi bokuqala embonini ukusebenzisa imishini yokupakisha ezenzakalelayo.Yaqala maphakathi nawo-1980 futhi inomlando weminyaka engaphezu kwengama-40.Ike yabhekana nenqubo yokushintsha kwefilimu yasekhaya yokupakishwa kwepulasitiki ukusuka ekuqaleni, isuka ohlotsheni olulodwa lwempahla iye ezinhlobonhlobo zezakhiwo ezihlukile.
Ukupakishwa kwe-Qingdao Advanmatchimiqulu yefilimu ene-laminated, ifilimu yokugoqa, i-rollstock(https://www.advanmatchpac.com/plastic-film-roll-product/) ohlelweni lokukhiqiza nokusebenzisa ifilimu yokupakisha yepulasitiki iminyaka engaphezu kwengu-20, sihlala sinamathela kumgomo wekhwalithi kuqala , futhi bazuze idumela elihle kumakhasimende.Ngakho-ke, ngalokhu ngifingqa izinkinga zekhwalithi yokubukeka, imiphumela, iziphakamiso zokuthuthukisa kanye nezindinganiso zokwamukela amanye amafilimu athengwe amakhasimende kwabanye abahlinzeki.Ngethemba ukuhlinzeka ngolwazi oluthile lwereferensi kubasebenzisi bokugcina.
Ukungezwani okungalingani
Ngesikhathi sokuhlukaniswa kwe-ifilimu roll, ngenxa yokungalingani kwamandla okuphakela nokuthulula, uma isilawuli singesihle, kuzovela isici sekhwalithi sokushuba kwesimo esingalingani somqulu wefilimu.Ngokuvamile kubonisa ukuthi ungqimba lwangaphakathi lweifilimu rolliqine kakhulu futhi ungqimba lwangaphandle luxega.Ukusetshenziswa komqulu onjalo wefilimu kuzodala ukusebenza okungazinzile komshini wokupakisha, njengosayizi ongalingani wokwenza isikhwama, ukuchezuka kokudonsa kwefilimu, kanye nokuchezuka kokuvala uphawu onqenqemeni, okuholela ekutheni imikhiqizo yokupakisha ingahlangabezani nezidingo zekhwalithi.Ngakho-ke, iningi lemikhiqizo enjalo yefilimu enesici iyabuyiselwa.
Ukuze ugweme le nkinga yekhwalithi, kuyadingeka ukuthatha izinyathelo zokulawula ezifanele ukuze kugcinwe ibhalansi yamandla asongayo.Njengamanje, imishini eminingi yokusika ifilimu inemishini yokulawula ukungezwani, engaqinisekisa ikhwalithi yokusika ifilimu.Kodwa-ke, ngezinye izikhathi ngenxa yezizathu zokusebenza, izizathu zemishini, umehluko omkhulu ngobukhulu nesisindo samakhoyili angenayo nakathulayo nezinye izici, ukukhubazeka kwekhwalithi enjalo kwenzeka ngezikhathi ezithile.Ngakho-ke, ukusebenza ngokucophelela kanye nokulungiswa okufika ngesikhathi kwemishini kuyadingeka ukuze kuqinisekiswe ikhwalithi yokushaya nokusika ifilimu roll.
Ubuso obungalingani
Ngokuvamile, ubuso bokuphela kwe-ifilimu rollkuyadingeka ukuze kube bushelelezi futhi kungabi nokungalingani.Uma ukungalingani kudlula u-2mm, kuzobhekwa njengokungafaneleki.Ubuso obungalingani bokuphela bubangelwa ikakhulukazi izici eziningi ezifana nokusebenza okungazinzile kwemishini yokugoqa nokusika, ubukhulu befilimu obungalingani, namandla okugoqa angalingani ngaphandle nangaphakathi.Imiqulu yefilimungezici ezinjalo zekhwalithi kuzophinde kubangele ukusebenza okungazinzile komshini wokupakisha, ukuchezuka kokudonsa ifilimu, ukuchezuka kokuvala uphawu onqenqemeni ngokweqile nezinye izenzakalo, ezingakwazi ukuhlangabezana nezidingo zekhwalithi zemikhiqizo yokupakisha efanelekayo.Ngakho-ke, imikhiqizo enjalo yekhwalithi enesici ngokuvamile iyanqatshwa.
Igagasi elingaphezulu
Okubizwa ngokuthi i-wavy surface yindawo engalingani, egobile futhi ene-wavy ye-membrane roll.Lesi sici sekhwalithi ngeke sibangele kuphela izinkinga ezibalwe ngenhla ekusetshenzisweni kwe-ifilimu roll, kodwa futhi kuthinte ngokuqondile ukusebenza kwezinto zokupakisha kanye nekhwalithi yokubukeka kwemikhiqizo yokupakisha, njengokusebenza okuphansi okuqinile kanye namandla okufaka uphawu ezinto ezibonakalayo, kanye nokuguqulwa kwamaphethini aphrintiwe nezikhwama ezakhiwe.Uma ukonakala kwekhwalithi kusobala kakhulu futhi kubi kakhulu, ikhoyili enjalo ayikwazi ukusetshenziswa emshinini wokupakisha ozenzakalelayo.
Ukuchezuka kwe-slitting okweqile
Ngokuvamile, ukuchezuka kwe-slitting ye-roll yefilimu kuyadingeka ukuthi kube phakathi kuka-2-3 mm.Okuningi kakhulu kuzothinta umphumela jikelele wesikhwama sokubumba, njenge-offset, ukungapheleli, i-asymmetry yesikhwama sokubumba kanye nezinye iziphambeko zekhwalithi yomkhiqizo wokupakisha.
Ikhwalithi ehlangene
Ikhwalithi ehlanganyelwe ngokuvamile isho izidingo zenombolo, ikhwalithi kanye nokumaka amalunga.Inani lamajoyinti avamile wefilimu lidingeka libe ngaphansi kuka-1 ku-90% wamaroli, futhi libe ngaphezu kuka-2 ku-10% wamaroli;Inani lamajoyinti anobubanzi beroli yefilimu elikhulu kuno-900mm liyadingeka ukuba libe ngaphansi kuka-3 ku-90% wamaroli, kanye no-4 kuya ku-5 ku-10% wamaroli.
I-film roll joint akumele idlulelane.Ukuhlangana kufanele kube phakathi kwamaphethini amabili.Isibopho kufanele siphelele, sibushelelezi futhi siqine.Itheyiphu yokunamathisela akufanele ibe mkhulu kakhulu.Uma kungenjalo, ifilimu izobe iboshwe futhi iphuke, okuholela ekuvaleni, okuthinta ukusebenza okuvamile komshini wokupakisha, ukwandisa umthwalo wokusebenza nokunciphisa ukusebenza kahle kokukhiqiza.Amalunga kufanele amakwe ngokucacile ukuze kube lula ukuhlolwa, ukusebenza kanye nokwelashwa.
Inkinga yekhwalithi eyinhloko
Ama-roll cores asetshenziswa kakhulu yizinto zephepha ezinobubanzi bangaphakathi obungama-76mm.Isici esiyinhloko sekhwalithi ukuguqulwa kwe-roll core, okubangela ukuthi ifilimu roll ingakwazi ukufakwa ngokujwayelekile ku-clamp yefilimu yomshini wokupakisha, ngakho ayikwazi ukusetshenziswa ekukhiqizeni.
Izizathu eziyinhloko zokuguqulwa kwe-roll core yomqulu wefilimu ukulimala kwezixhumanisi zokulondoloza nezokuthutha, ukuchotshozwa kwe-roll core ngenxa yokucindezeleka okweqile kwe-roll yefilimu, ikhwalithi embi namandla aphansi e-roll core.
Indlela yokubhekana nalesi sici sekhwalithi ngokuvamile ukuyibuyisela kumnikezeli ukuze ihlehliselwe emuva nokushintshwa okubalulekile.
Roll inkomba
Imishini eminingi yokupakisha ezenzakalelayo inezidingo ezithile zokuqondisa ifilimu ephumela ngaphandle.Le mfuneko inqunywa ngokuyinhloko ngokusho kwesakhiwo somshini wokupakisha kanye nomklamo wephethini wokuhlobisa wemikhiqizo yokupakisha.Ngokuvamile ngezansi noma phezulu kuqala ukuphuma.Ngokuvamile, le mfuneko icaciswa ekucacisweni noma kumazinga ekhwalithi yezinto zokupakisha zomkhiqizo ngamunye.Izimo ezinjalo zekhwalithi azivamile ngaphansi kwezimo ezivamile.
Ubuningi bokwenza isikhwama
Ngokuvamile, ubude bomqulu wefilimu buyiyunithi yokulinganisa.Ubude bunqunywa ngokuyinhloko ubukhulu be-diameter yangaphandle kanye nomthamo womthwalo wefilimu osebenza emshinini wokupakisha, futhi ngokuvamile usetshenziswa ku-Meters / roll.
Ukukhubazeka kwekhwalithi yenombolo enganele yezikhwama zefilimu nakho akuvamile, kodwa kokubili umphakeli nomthengi bakhathazekile ngakho.Abakhiqizi abaningi banokuhlola inkomba yokusetshenziswa kwekhoyili yefilimu.Ngaphezu kwalokho, ayikho indlela enhle yokulinganisa okunembile nokuhlolwa kwekhoyili yefilimu ngesikhathi sokulethwa nokwamukelwa.Ngakho-ke, kuvame ukuba nemibono ehlukene noma izingxabano mayelana nalesi sici sekhwalithi, esivame ukuxazululwa ngezingxoxo.
Ukonakala komkhiqizo
Ukulimala komkhiqizo ngokuvamile kwenzeka phakathi nenqubo kusukela ekuqedeni ukuhlukaniswa komkhiqizo kuya ekulethweni komkhiqizo.Kunomonakalo omkhulu wamaroli efilimu (njengokuklwejwa, ukudabuka, imbobo…), ukungcoliswa kwamaroli efilimu, ukulimala kwephakheji yangaphandle (umonakalo, amanzi, ukungcola…), njll.
Ukuze ugweme amaphutha anjalo ekhwalithi, kuyadingeka ukuqinisa ukuphathwa kwezixhumanisi ezifanele, ukwamukela ukusebenza okujwayelekile kanye nezinyathelo zokuvimbela eziphumelelayo.
Ukuhlonza umkhiqizo
Iifilimu rollizoba namamaki omkhiqizo acacile naphelele, futhi okuqukethwe okuyinhloko kuzofaka: igama lomkhiqizo, ukucaciswa, inani lokupakisha, inombolo ye-oda, usuku lokukhiqiza, ikhwalithi kanye nolwazi lomhlinzeki.
Inhloso eyinhloko yalolu lwazi ukuhlangabezana nezidingo zokuhlolwa nokwamukelwa kokulethwa, ukugcinwa nokulethwa, ukukhiqizwa nokusetshenziswa, ukulandelela ikhwalithi, njll. Gwema ukulethwa nokusetshenziswa okungalungile.
Amaphutha ekhwalithi yokubukeka kwefilimu ngokuvamile avela ohlelweni olulandelayo lokukhiqizwa kwefilimu kanye nenqubo yokugcinwa nokuthutha.Ngakho-ke, ukulawulwa kwekhwalithi yalesi sixhumanisi kungathuthukisa kakhulu izinga lokufaneleka komkhiqizo wokufakwayo, futhi kuzuze umphumela ophindwe kabili ngesigamu somzamo wokuthuthukisa ikhwalithi yomkhiqizo nokuthuthukisa izinzuzo zezomnotho zebhizinisi.
