Ngokusetshenziswa kabanzi kwe-othomathikhiifilimu yokupakisha, ukunaka kwefilimu yokupakisha okuzenzakalelayo kuyanda. Ngezansi kunezinkinga eziyi-10 ezihlangatshezwana nefilimu yokupakisha ezenzakalelayo lapho kwenziwa izikhwama:
1. Ukungezwani okungalingani
Ukungezwani okungalingani kumaroli efilimu kuvame ukubonakala njengoba ungqimba lwangaphakathi luminyene kakhulu futhi ungqimba lwangaphandle luxega. Uma lolu hlobo lomqulu wefilimu lusetshenziswa emshinini wokupakisha ozenzakalelayo, luzobangela ukusebenza okungaqinisekile komshini wokupakisha, okuholela ekungalingani kwesikhwama, ukuchezuka kokudonsa kwefilimu, ukuchezuka kokuvala uphawu onqenqemeni ngokweqile, nezinye izenzakalo, okuholela emikhiqizweni yokupakisha engahlangabezani nezidingo zekhwalithi. Ngakho-ke, kunconywa ukubuyisela imikhiqizo ye-roll yefilimu eneziphambeko ezinjalo. Ukungezwani kokungalingani kwefilimu ikakhulukazi kubangwa ukungezwani okungalingani phakathi kwe-roll ne-out roll ngesikhathi sokusika. Nakuba imishini eminingi yokusika ifilimu okwamanje inamadivayisi okulawula ukungezwani ukuze kuqinisekiswe ikhwalithi yokunqunywa kwamaroli efilimu, ngezinye izikhathi inkinga yokushuba okungalingani ekuhlinzeni kwamaroli efilimu isavela ngenxa yezici ezihlukahlukene njengezizathu zokusebenza, izizathu zemishini, kanye nomehluko omkhulu ngobukhulu nesisindo samaroli angenayo naphumayo. Ngakho-ke, kuyadingeka ukuhlola ngokucophelela futhi ulungise imishini ukuze uqinisekise ukungezwani kokusika okulinganiselwe kwe-roll yefilimu.
2.Ubuso bokuphela obungalingani
Ngokuvamile, ubuso bokuphela kwe-ukupakisha ifilimu rollkudinga ubushelelezi nokungalingani. Uma ukungalingani kudlula u-2mm, kuzobhekwa njengomkhiqizo ongavumelani futhi ngokuvamile kunqatshwe. Amaroli efilimu anobuso obungalingani ekugcineni angabangela nokusebenza okungazinzile kwemishini yokupakisha ezenzakalelayo, ukuchezuka kokudonsa ifilimu, kanye nokuchezuka kokuvala onqenqemeni okukhulu. Izizathu eziyinhloko zokungalingani kobuso bokuphela komqulu wefilimu yilezi: ukusebenza okungazinzile kwemishini yokusika, ubukhulu befilimu obungalingani, ukungezwani okungalingani ngaphakathi nangaphandle komqulu, njll, okungabhekwa futhi kulungiswe ngokufanele.
3. Igagasi elingaphezulu
I-Wavy surface ibhekisela endaweni engalingani futhi enamagagasi yomqulu wefilimu. Lesi sici sekhwalithi sizophinde sithinte ngokuqondile ukusebenza komqulu wefilimu emshinini wokupakisha ozenzakalelayo, futhi kuthinte ikhwalithi yomkhiqizo wokugcina opakishiwe, njengokusebenza okuqinile kwempahla yokupakisha, ukuncipha kwamandla okuvala, amaphethini aphrintiwe, ukuwohloka kwesikhwama esakhiwe, njll. Uma izici ezinjalo zekhwalithi zisobala kakhulu, amaroli anjalo amafilimu awakwazi ukusetshenziswa emishinini yokupakisha ezenzakalelayo.
4. Ukuchezuka kokusika ngokweqile
Ngokuvamile, kuyadingeka ukulawula ukuphambuka kwe-slitting yefilimu egoqiwe ngaphakathi kuka-2-3 mm. Ukuchezuka kwe-slitting okweqile kungathinta umphumela ophelele wesikhwama esakhiwe, njengokuchezuka kwendawo yephethini, ukungapheleli, isikhwama esakhiwe nge-asymmetric, njll.
5. Izinga eliphansi lamalunga
Izinga lamalunga ngokuvamile lisho izidingo zenani, ikhwalithi, kanye nokulebula kwamalunga. Ngokuvamile, imfuneko yenani lamajoyinti e-film roll iwukuba u-90% wamajoyinti e-roll yefilimu abe ngaphansi kuka-1, futhi u-10% wamajoyinti e-film roll abe nangaphansi kuka-2. Uma ububanzi bomqulu wefilimu bukhulu kuno-900mm, imfuneko yenombolo yamalunga ukuthi amalunga angu-90% we-roll yefilimu angaphansi kuka-3, futhi u-10% wefilimu angaba u-10% ohlangene. I-roll yefilimu kufanele ibe isicaba, ibushelelezi, futhi iqine, ngaphandle kokugqagqana noma ukweqa. Ukuma okuhlanganyelwe kufanele kube phakathi kwamaphethini amabili, futhi i-tape yokunamathisela akufanele ibe mkhulu kakhulu, ngaphandle kwalokho izobangela ukuqhuma kwefilimu, ukuphuka kwefilimu, nokuvalwa, okuthinta ukusebenza okuvamile komshini wokupakisha othomathikhi. Ngaphezu kwalokho, kufanele kube nezimpawu ezicacile emalungeni ukuze zihlolwe kalula, zisebenze, futhi ziphathwe.
6. I-core deformation
Ukuguqulwa komgogodla kuzobangela ukuthi ifilimu roll ingakwazi ukufakwa kahle kumshini wokupakisha wefilimu ozenzakalelayo. Izizathu eziyinhloko ze-deformation ye-core of the film roll ukulimala komgogodla ngesikhathi sokugcinwa nokuthutha, ukuchotshozwa komnyombo ngenxa yokungezwani ngokweqile kumqulu wefilimu, izinga eliphansi namandla aphansi omgogodla. Kumaroli efilimu anama-core akhubazekile, ngokuvamile adinga ukubuyiselwa kumnikezeli ukuze ahlehliswe futhi ashintshwe.
7. Ukuqondisa okungalungile kwefilimu
Imishini eminingi yokupakisha ezenzakalelayo inezidingo ezithile zokuqondiswa komqulu wefilimu, njengokuthi iphansi kuqala noma phezulu kuqala, okuncike kakhulu ekwakhiweni komshini wokupakisha kanye nokuklanywa kwephethini yokuhlobisa umkhiqizo wokupakisha. Uma isiqondiso sefilimu singalungile, sidinga ukuphindiselwa. Ngokuvamile, abasebenzisi banezidingo ezicacile kumazinga ekhwalithi yefilimu, futhi ngaphansi kwezimo ezijwayelekile, izinkinga ezinjalo azivamile.
8. Inani elenele lokwenza isikhwama
Ngokuvamile, amaroli efilimu akalwa ngobude, njengamakhilomitha umqulu ngamunye, futhi inani elithile lincike ikakhulukazi kububanzi obuphezulu obungaphandle nomthamo womthwalo wefilimu osebenza emshinini wokupakisha. Zombili izinhlangothi zokuhlinzeka nezidingo zikhathazekile ngenani lezikhwama zefilimu, futhi abasebenzisi abaningi badinga ukuhlola inkomba yokusetshenziswa kwamaroli wefilimu. Ngaphezu kwalokho, ayikho indlela enhle yokulinganisa okunembile nokuhlolwa kwamaroli efilimu ngesikhathi sokulethwa nokwamukelwa. Ngakho-ke, ubuningi bokwenza izikhwama obanele ngokuvamile budala izingxabano phakathi kwezinhlangothi zombili, ngokuvamile ezidinga ukuxazululwa ngezingxoxo.
9. Ukonakala komkhiqizo
Ukulimala komkhiqizo kuvame ukwenzeka kusukela ekuqedweni kokusikwa kuya ekulethweni, ikakhulukazi okuhlanganisa nokulimala kwefilimu (okufana nokuklwebheka, izinyembezi, izimbobo),ifilimu yepulasitiki rollukungcola, umonakalo wokupakisha wangaphandle (umonakalo, umonakalo wamanzi, ukungcola), njll.
10. Ukulebula komkhiqizo okungaphelele
Uhlu lwefilimu kufanele lube nokulebula komkhiqizo okucacile nokuphelele, okuhlanganisa ikakhulukazi: igama lomkhiqizo, imininingwane, inani lokupakishwa, inombolo ye-oda, idethi yokukhiqiza, ikhwalithi, nolwazi lomhlinzeki. Lokhu ikakhulukazi ukuhlangabezana nezidingo zokwamukelwa kokulethwa, ukugcinwa nokuthunyelwa, ukusetshenziswa kokukhiqiza, ukulandelela ikhwalithi, njll., nokugwema ukulethwa nokusetshenziswa okungalungile.
