Ngophuhliso kunye nenkqubela phambili yezixhobo zokupakisha, ukusetyenziswa koomatshini bokupakisha ngokuzenzekelayo kuxhaphake ngakumbi, ngakumbi kwi-detergent, izimonyo, ukutya, amayeza kunye namanye amashishini.I-Henkel China isepha ngomnye wabavelisi bokuqala kwishishini ukusebenzisa oomatshini bokupakisha ngokuzenzekelayo.Yaqala phakathi kwiminyaka yee-1980 kwaye inembali engaphezulu kweminyaka engama-40.Ifumene inkqubo yokutshintsha kwefilimu yasekhaya yokupakishwa kweplastiki ukusuka ekuqaleni, ukusuka kuluhlu olulodwa lwemathiriyeli ukuya kwiintlobo ezahlukeneyo zezakhiwo zemathiriyeli.
Ukupakishwa kweQingdao Advanmatchimiqulu yefilimu elaminated, ifilimu yomqulu, i-rollstock (https://www.advanmatchpac.com/plastic-film-roll-product/) kwinkqubo yokuvelisa kunye nokusebenza ifilimu yokupakisha yeplastiki ngaphezu kweminyaka engama-20, sihlala sithobela umgaqo womgangatho kuqala , kwaye baphumelele igama elihle kubathengi.Ke ngoko, ndishwankathela iingxaki zomgangatho wembonakalo, iziphumo, iingcebiso zokuphucula kunye nemigangatho yokwamkelwa kwezinye iifilimu ezithengwe ngabathengi kwabanye ababoneleli.Ndiyathemba ukubonelela ngolwazi lwereferensi kubasebenzisi bokugqibela.
Uxinzelelo olungalinganiyo
Ngexesha lokunqunyulwa kweumqulu wefilimu, ngenxa yokungalingani kwemikhosi yokutya kunye nokukhulula, emva kokuba ulawulo lungekho kakuhle, isiphene somgangatho wokungahambelani kwe-wind winding of the film roll iya kuvela.Ngokuqhelekileyo ibonisa ukuba umaleko wangaphakathi weumqulu wefilimuiqine kakhulu kwaye umaleko wangaphandle ukhululekile.Ukusetyenziswa komqulu wefilimu onjalo kuya kubangela ukusebenza okungazinzanga komatshini wokupakisha, njengobungakanani bokwenza ingxowa engalinganiyo, ukutenxa kwefilimu, kunye nokuphambuka okugqithisileyo kokutywinwa komphetho, okukhokelela ekubeni iimveliso zokupakisha zingahlangabezani neemfuno zomgangatho.Ke ngoko, uninzi lweemveliso zefilim ezineziphene ziyabuyiswa.
Ukuze ugweme le ngxaki yomgangatho, kuyimfuneko ukuthatha amanyathelo afanelekileyo okulawula ukugcina ukulingana kwamandla omoya.Okwangoku, uninzi loomatshini bokuqhawula ifilimu banezixhobo zokulawula uxinezeleko, ezinokuqinisekisa umgangatho wokunqunyulwa kwefilimu.Nangona kunjalo, ngamanye amaxesha ngenxa yezizathu zokusebenza, izizathu zezixhobo, ulwahlulo olukhulu kubungakanani kunye nobunzima beekhoyili ezingenayo kunye nezothulwa kunye nezinye izinto, iziphene zomgangatho ezinjalo zenzeka ngamaxesha athile.Ke ngoko, ukusebenza ngokucokisekileyo kunye nokulungelelaniswa kwangexesha kwezixhobo kuyadingeka ukuze kuqinisekiswe umgangatho wefilim roll amanqaku kunye nokusika.
Ubuso obungalinganiyo
Ngokuqhelekileyo, isiphelo sobuso beumqulu wefilimukufuneka ibe mpuluswa kwaye ikhululeke kukungalingani.Ukuba ukungalingani kudlula i-2mm, kuya kugwetywa njengento engafanelekanga.Ubuso obungalinganiyo besiphelo bubangelwa ikakhulu zizinto ezininzi ezifana nokusebenza okungazinzanga kwezixhobo zokujiya kunye nokusika, ubukhulu befilimu obungalinganiyo, kunye namandla angalinganiyo okudibanisa ngaphakathi nangaphandle.Imiqulu yefilimukunye neziphene ezisemgangathweni ziya kubangela ukusebenza okungazinzanga komatshini wokupakisha, ukutenxa ifilimu yokutsalwa, ukutenxa ngokugqithisileyo kokutywinwa komphetho kunye nezinye izinto ezingenakuhlangabezana neemfuno zomgangatho weemveliso zokupakisha ezifanelekileyo.Ngoko ke, iimveliso ezinjalo ezinomgangatho onjalo zihlala zikhatywa.
Umphezulu wamaza
Into ebizwa ngokuba yi-wavy surface yindawo engalinganiyo, egobileyo kunye ne-wavy ye-membrane roll.Esi siphene somgangatho asiyi kubangela kuphela iingxaki ezikhankanywe ngasentla ekusebenziseni iumqulu wefilimu, kodwa kwakhona kuchaphazela ngokuthe ngqo ukusebenza kwezinto zokupakisha kunye nomgangatho wokubonakala kweemveliso zokupakisha, ezifana nokusebenza okuphantsi kwe-tensile kunye namandla okutywinwa kwezinto, kunye nokuguqulwa kweepatheni eziprintiweyo kunye neengxowa ezenziwe.Ukuba i-defect esemgangathweni ibonakala kakhulu kwaye inzulu, i-coil enjalo ayikwazi ukusetyenziswa kumatshini wokupakisha ngokuzenzekelayo.
Ukutenxa ngokugqithisileyo kokunqunyulwa
Ngokuqhelekileyo, ukuphambuka kwe-slitting yomqulu wefilimu kuyadingeka ukuba kube ngaphakathi kwe-2-3 mm.Ubuninzi kakhulu buya kuchaphazela umphumo opheleleyo wesikhwama sokubumba, njenge-offset, incompleteness, i-asymmetry yesikhwama sokubumba kunye nezinye iziphene zomgangatho wemveliso yokupakisha.
Umgangatho odibeneyo
Umgangatho odibeneyo ngokuqhelekileyo ubhekisela kwiimfuno zenani, umgangatho kunye nokumakishwa kwamalungu.Inani leengqungquthela zefilimu eziqhelekileyo zifunekayo ukuba zibe ngaphantsi kwe-1 kwi-90% ye-rolls, kwaye ngaphezu kwe-2 kwi-10% ye-rolls;Inani lamalungu ane-diameter ye-film roll engaphezulu kwe-900mm kufuneka ibe ngaphantsi kwe-3 kwi-90% ye-rolls, kunye ne-4 ukuya kwi-5 kwi-10% ye-rolls.
Umdibaniso wefilimu awuyi kutyholwa ngokugqith' emgceni.Isiphambuka siya kuba sembindini weepateni ezimbini.Ukudibanisa kuya kuba okupheleleyo, okugudileyo kunye nokuqina.Iteyiphu yokuncamathela ayiyi kuba ngqindilili kakhulu.Ngaphandle koko, ifilimu iya kuxutywa kwaye iphulwe, kubangele ukuvala, okuchaphazela ukusebenza okuqhelekileyo komatshini wokupakisha, ukwandisa umthwalo wokusebenza kunye nokunciphisa ukusebenza kakuhle kwemveliso.Amalungu aya kuphawulwa ngokucacileyo ukuququzelela ukuhlolwa, ukusebenza kunye nonyango.
Ingxaki yomgangatho ongundoqo
I-roll cores esetyenziswa ngokuqhelekileyo zizinto zephepha ezinobubanzi obuyi-76mm ngaphakathi.I-defect ephambili yekhwalithi yi-deformation ye-roll core, ebangela ukuba ifilimu yefilimu ingakwazi ukufakwa ngokuqhelekileyo kwi-clamp yefilimu yomatshini wokupakisha, ngoko ayikwazi ukusetyenziswa kwimveliso.
Izizathu eziphambili ze-deformation ye-roll core ye-film roll ngumonakalo wokugcinwa kunye nokuthutha amakhonkco, ukutyunyuzwa kwe-roll core ngoxinzelelo olugqithiseleyo lwefilimu, umgangatho ombi kunye namandla aphantsi e-roll core.
Indlela yokujongana nesi siphene somgangatho ikholisa ukuyibuyisela kumboneleli ukuze ibuyiselwe umva kunye notshintsho olungundoqo.
Roll indlela
Uninzi koomatshini bokupakisha ngokuzenzekelayo banemfuno ezithile kwicala lefilimu ephumayo.Le mfuneko inqunywe ngokukodwa ngokwesakhiwo somatshini wokupakisha kunye noyilo lwepateni yokuhlobisa yeemveliso zokupakisha.Ngokuqhelekileyo ezantsi okanye phezulu kuqala ngaphandle.Ngokuqhelekileyo, le mfuneko ichazwe kwiinkcukacha okanye imigangatho yomgangatho wezinto zokupakisha zemveliso nganye.Iziphene zomgangatho ezinjalo zinqabile phantsi kweemeko eziqhelekileyo.
Ubungakanani bokwenza ingxowa
Ngokuqhelekileyo, ubude bomqulu wefilimu yiyunithi yokulinganisa.Ubude ubukhulu becala bugqitywe ngobuninzi bangaphandle kunye nomthamo womthwalo wefilimu umqulu osebenzayo kumatshini wokupakisha, kwaye udla ngokusetyenziswa kwiimitha / umqulu.
Isiphene somgangatho wenani elinganeleyo leengxowa zefilimu zefilimu nazo aziqhelekanga, kodwa bobabini umthengisi kunye nomthengi banenkxalabo malunga nayo.Uninzi lwabavelisi banovavanyo kwisalathiso sokusetyenziswa kwekhoyili yefilimu.Ukongezelela, akukho ndlela efanelekileyo yokulinganisa ngokuchanekileyo kunye nokuhlolwa kwekhoyili yefilimu ngexesha lokunikezelwa kunye nokwamkelwa.Ke ngoko, kukho iimbono ezahlukeneyo okanye iingxabano malunga nesi siphene somgangatho, ezidla ngokusonjululwa ngothethathethwano.
Umonakalo wemveliso
Umonakalo wemveliso ubukhulu becala ubakho ngexesha lenkqubo ukusuka ekugqityweni kokunqunyulwa kwemveliso ukuya kunikezelo lwemveliso.Kukho ubukhulu becala umonakalo wefilim (njengomkrwelo, ukukrazuka, umngxuma…), ungcoliseko lwefilim, ukonakala kwephakheji yangaphandle (umonakalo, amanzi, ungcoliseko…), njl.
Ukuze ugweme iziphene zomgangatho onjalo, kuyimfuneko ukuqinisa ulawulo lweekhonkco ezifanelekileyo, ukwamkela ukusebenza okusemgangathweni kunye namanyathelo okukhusela asebenzayo.
Ukuchongwa kwemveliso
Iumqulu wefilimuiya kuba namanqaku emveliso acacileyo kwaye apheleleyo, kwaye imixholo ephambili iya kubandakanya: igama lemveliso, ukucaciswa, ubungakanani bokupakishwa, inombolo ye-odolo, umhla wokuvelisa, umgangatho kunye nolwazi lomthengisi.
Injongo ephambili yolu lwazi kukuhlangabezana neemfuno zokuhlolwa kokuhanjiswa kunye nokwamkelwa, ukugcinwa kunye nokuhanjiswa, ukuveliswa kunye nokusetyenziswa, ukulandelela umgangatho, njl.
Iziphene zomgangatho wembonakalo yefilim zivela ikakhulu kwinkqubo elandelayo yokuveliswa kwefilimu kunye nenkqubo yokugcinwa kunye nokuthutha.Ngoko ke, ukulawulwa komgangatho weli khonkco kunokuphucula kakhulu izinga lokufaneleka kwemveliso yegalelo-imveliso, kwaye kuphumelele kabini umphumo ngesiqingatha somzamo wokuphucula umgangatho wemveliso kunye nokuphucula izibonelelo zoqoqosho zeshishini.
