1. Amaphakheji avaliwe
Lolu hlobo lokupakisha lufana ne-shrink film package.Ifilimu isonga ithreyi ethreyini, bese kuba izibambo ezimbili ezishisayo zivala ifilimu kuzo zombili iziphetho.Lolu uhlobo lokuqala lokusebenzisa ifilimu enwetshiwe, futhi amafomu amaningi okupakisha enziwe kusukela kulokhu
2. Ukupakishwa kobubanzi obugcwele
Lolu hlobo lokupakisha ludinga ukuthi ifilimu ibe banzi ngokwanele ukumboza i-pallet, futhi ukuma kwephalethi kujwayelekile, ngakho-ke inokwayo, ilungele ukushuba kwefilimu okungu-17～35μm.
3. Ukupakisha okwenziwa ngesandla
Lolu hlobo lokupakisha luwuhlobo olulula kakhulu lokupakishwa kwefilimu elula.Ifilimu ifakwe ku-rack noma ibanjwe ngesandla, ijikeleziswa ngethreyi noma ifilimu izungeza ithreyi.Isetshenziselwa ikakhulukazi ukupakishwa kabusha ngemuva kokulimala kwe-pallet eboshwe, kanye nokupakishwa kwe-pallet evamile.Lolu hlobo lwejubane lokupakisha luhamba kancane, futhi ubukhulu befilimu obufanele bungama-15-20μm;
4. Yelula ifilimu ukusonga umshini emaphaketheni
Lolu uhlobo oluvame kakhulu futhi olubanzi lokupakisha ngomshini.Ithreyi liyazungeza noma ifilimu izungeza ithreyi.Ifilimu igxilwe kubakaki futhi ingakwazi ukuhamba phezulu naphansi.Lolu hlobo lomthamo wokupakisha lukhulu kakhulu, cishe amathreyi ayi-15-18 ngehora.Ubukhulu befilimu obufanele bungaba ngu-15-25μm;
5. Ukupakishwa kwemishini evundlile
Ihluke kwamanye amaphakheji, ifilimu izungeza isihloko, esifanele ukupakishwa kwezimpahla ezinde, njengamakhaphethi, amabhodi, ama-fiberboards, izinto ezimise okukhethekile, njll.;
6. Ukupakishwa kwamashubhu ephepha
Lokhu kungenye yezinto zakamuva ezisetshenziswayo zefilimu enwetshiwe, engcono kunepaki yakudala yamashubhu ephepha.Ubukhulu befilimu obufanele bungama-30～120μm;
7. Ukupakisha izinto ezincane
Lona uhlobo lwakamuva lokupakisha lwefilimu elula, elingakwazi ukunciphisa ukusetshenziswa kwezinto ezibonakalayo kuphela, kodwa futhi linciphise indawo yokugcina ama-pallets.Emazweni angaphandle, lolu hlobo lokupakisha lwaqala ukwethulwa ngo-1984. Ngemva konyaka owodwa, amaphakheji amaningi anjalo avela emakethe.Leli fomu lokupakisha linamandla amakhulu.Ifanele ukushuba kwefilimu okungu-15～30μm;
8. Ukupakishwa kwamashubhu nezintambo
Lesi isibonelo sokusetshenziswa kwefilimu yokwelula emkhakheni okhethekile.Impahla yokupakisha ifakwe ekupheleni komugqa wokukhiqiza.Ifilimu yokwelula ezenzakalelayo ngokugcwele ayikwazi ukufaka esikhundleni se-tape kuphela ukuze ibophe izinto ezibonakalayo, kodwa futhi idlale indima yokuzivikela.Ugqinsi olusebenzayo luyi-15-30μm.
9. Indlela yokwelula ye-pallet mechanism
Ukupakishwa kwefilimu enwetshiwe kufanele kunwetshwe, futhi izinhlobo ezinwebekayo zokupakishwa kwemishini ye-pallet zihlanganisa ukwelula okuqondile kanye nokwelula kwangaphambili.Kunezinhlobo ezimbili ze-pre-stretching, enye i-roll pre-stretching kanti enye i-electric stretching.
Ukwelula okuqondile ukuqedela ukwelula phakathi kwethreyi nefilimu.Le ndlela inesilinganiso esiphansi sokwelula (cishe 15% -20%).Uma isilinganiso sokunwebeka sidlula u-55%～60%, esidlula iphuzu lokuqala lefilimu, ububanzi befilimu buyancishiswa, nokusebenza kokubhoboza nakho kuyalahleka.Kulula ukuphuka.Futhi ngesilinganiso sokunwebeka esingu-60%, amandla okudonsa asemakhulu kakhulu, futhi ezimpahleni ezilula, kungenzeka akhubaze izimpahla.
Ukwelula kwangaphambili kwenziwa ngama-roller amabili.Amarola amabili e-roller pre-stretching axhunywe ndawonye ngeyunithi yegiya.Isilinganiso sokwelula singahluka ngokuya ngesilinganiso segiya.Amandla okudonsa akhiqizwa i-turntable.Njengoba ukwelula kukhiqizwa ebangeni elifushane, ukungqubuzana phakathi kwe-roller nefilimu Kubuye kukhulu, ngakho ububanzi befilimu abunciphisi, futhi ukusebenza kwe-puncture kwasekuqaleni kwefilimu nakho kugcinwa.Akukho ukwelula okwenzeka ngesikhathi sokusonga kwangempela, okunciphisa ukuphuka okubangelwa imiphetho ebukhali noma amakhona.Lokhu kunwetshwa kwangaphambili kungakhuphula isilinganiso sokwelula sibe ngu-110%.
Indlela yokwelula yokunwetshwa kukagesi kwangaphambili iyafana naleyo yokwelula kwangaphambili.Umehluko wukuthi imiqulu emibili iqhutshwa ugesi, futhi ukwelula kuzimele ngokuphelele ekujikelezeni kwethreyi.Ngakho-ke, ivumelana nezimo, ifanele izimpahla ezilula, ezinzima, nezingajwayelekile.Ngenxa yokucindezeleka okuphansi ngesikhathi sokupakisha, isilinganiso sangaphambili sokwelula sale ndlela siphezulu ku-300%, okusindisa kakhulu izinto futhi kunciphisa izindleko.Ifanele ukushuba kwefilimu okungu-15-24μm.
