Njengoba amabhizinisi amaningi asebenzisa isivinini esikhulu
ukupakisha okuzenzakalelayo umshini, enqubweni yokupakisha okuzenzakalelayo kwejubane eliphezulu lefilimu yokupakisha eguquguqukayo yezikhwama ezidabukile, ukuqhekeka, ukubola, ukufaka uphawu lokushisa, izinkinga zekhwalithi yokuvala njengokungcola kancane kancane ziba yisidingo sebhizinisi sokugxila ezinkingeni zenqubo yokulawula.
amabhizinisi okupakisha aguquguqukayo ekukhiqizeni umshini wokupakisha othomathikhi wesivinini esikhulu usebenzisa i-reel yefilimu, kufanele anake lokhu okulandelayo:
1, umqulu wezidingo ezibonakalayo zezendlalelo zefilimu
ngenxa yesivinini esikhulu somshini wokupakisha othomathikhi wesakhiwo semishini yehlukile komunye umshini wokwenza izikhwama, ukucindezela kwawo kumasondo amabili kuphela noma i-athikili yokucindezela okushisayo kuphoqa omunye nomunye ukufeza uphawu lokushisa, futhi akukho thuluzi lokupholisa, ungqimba lwefilimu lokuphrinta luthintana ngqo. idivayisi yokuvala ukushisa, ngaphandle kokuvikelwa kwendwangu yokufaka.
Ngakho-ke, ukuphrinta ngesivinini esiphezulu ukukhetha kwento ngayinye yesendlalelo kubaluleke kakhulu.
Izohambisana nezidingo ngaphakathi kwethebula elingezansi:
2, ezinye izakhiwo kufanele zihambisane nalokhu:
1)
Ibhalansi yokuqina kwefilimu
ukushuba kwefilimu yepulasitiki, ukushuba okumaphakathi nokubekezelelana kokuqina, ekuhlaziyeni kokugcina ubukhulu be-diaphragm.
Enqubweni yokukhiqiza kufanele ilawule ukufana kwefilimu ukujiya, imikhiqizo ekhiqizwe ngaphandle kwalokho, akuwona umkhiqizo omuhle, umkhiqizo omuhle kufanele ube mpo futhi uvundlile kubukhulu bokulingana.
Ngenxa yezinhlobo ezahlukene zemiphumela yokusetshenziswa kwefilimu emincane ihlukile, ukushuba okumaphakathi nokubekezelelana kokuqina kuhlukile futhi.
Mayelana nomehluko ojwayelekile wokupakisha okuzenzakalelayo wokupakisha okuzenzakalelayo awukho ngaphezu kwe-15 um.
2)
Izakhiwo ze-optical zefilimu ezacile
ibhekisela kunkungu, obala, ukudlulisa ukukhanya kwamafilimu amancane.
ngenxa yalokho, umqulu wefilimu wokukhethwa kwezithasiselo ze-masterbatch kanye nobuningi bokwengeza kunezidingo ezikhethekile nokulawula, futhi unokucaca okuhle, kodwa futhi ufuna ukucabangela ubulili obuvulekile kanye nezinga elibushelelezi le-membrane, umthamo ovulekile wokugoqa ifilimu, ukugoqa. , akwenzeki phakathi kokunamathela kwefilimu kumgomo.
Uma inani liningi kakhulu lizothinta inkungu yefilimu.
Ukukhanya okujwayelekile kufanele kube ngaphezu kwama-92%.
3)
I-friction coefficient
i-coefficient of friction ingahlukaniswa ibe yi-static friction kanye ne-dynamic friction system.
Imikhiqizo yezigubhu zokupakishwa ezizenzakalelayo, ngaphezu kwe-coefficient yokuhlola ukungqubuzana kwesimo esijwayelekile, kufanele futhi ibe ifilimu yokuhlola kanye ne-coefficient yokushayisana yepuleti lensimbi engenasici, ngenxa yokuthi ungqimba oluvala ukushisa lwefilimu lokupakisha oluzenzakalelayo luthintana ngqo nomshini wokubumba othomathikhi wokupakisha. i-coefficient yokushayisana kufanele ibe ngaphansi kuka-0.
4 u.
4)
Engeza umthamo
ngokujwayelekile kufanele ilawulwe ngaphakathi kwe-300 ~ 500 PPM, ukuvuleka kwethonya elincane kakhulu, njll. Umsebenzi we-membrane, kakhulu uzobhubhisa amandla ahlanganisiwe.
Futhi ukuvimbela izithasiselo ohlelweni lokusebenzisa inombolo enkulu yokufuduka noma ukungena.
Engeza umthamo ezingxenyeni ezingu-500 ~ 800 esigidini ngasinye, kufanele kusetshenziswe ngokucophelela, imithamo engezayo engaphezu kuka-800 PPM, ngokuvamile ungayisebenzisi.
5)
I-membrane eyinhlanganisela yokufinyela okuvumelanayo nokuvumelanayo
ukufinyezwa kwe-asynchronous kufakwe ekushintsheni kwezinto zokugoqa kanye ne-warping, ukufinyela kwe-asynchronous kunokuvulwa kwesikhwama & nokunye;
Curl ngaphakathi & kulo lonke;
Noma & nokunye
I-curl yangaphandle & kuyo yonke;
Izinhlobo ezimbili zamafomu, lesi simo sibonisa ukuthi ifilimu eyinhlanganisela ngaphezu kokufinyela okuvumelanayo isekhona ngaphakathi kokufinyela okungavumelani (asynchronous contraction)
Ingcindezi eshisayo noma ohlangothini oluhlukile nosayizi wokuncipha)
.
Ngakho-ke lapho uthenga ifilimu, kufanele ibe sesimweni esifanayo, kuzo zonke izinhlobo zezinto ezihlanganisiwe zokushisa (
Kuyashisa futhi kunomswakama)
Ukuhlolwa kokuncipha kwe-longitudinal nokuphambene, futhi umehluko wakho kokubili awukwazi ukwehluka kakhulu, cishe u-0.5% kangcono.
Lezi sisindo se-weigher
multihead weigher zenzelwe ukusebenza njengomhlahlandlela wabanikazi bamabhizinisi wokuthi bangawahlonza kanjani amathuba okuqamba izinto ezintsha kanye nendlela yokuzijwayeza nobuchwepheshe obushintsha njalo banamuhla.
