Imishini yokupakisha ye-Vertical form fill seal (VFFS).asetshenziswa cishe kuzo zonke izimboni namuhla, ngesizathu esihle: Ziyizixazululo zokupakisha ezisheshayo, ezongayo ezigcina indawo ebalulekile yezitshalo.
Noma ngabe umusha emshinini wokupakisha noma usuvele unamasistimu amaningi, kungenzeka ukuthi uyafuna ukwazi ukuthi asebenza kanjani. Kulesi sihloko, sihamba ngendlela umshini oqondile wokugcwalisa ifomu ovula ngayo umqulu wefilimu yokupakisha ibe isikhwama esiqediwe esilungele ishalofu.
Imishini yokupakisha eyenziwe lula, eqondile iqala ngomqulu omkhulu wefilimu, iyenze ibe yisimo sesikhwama, igcwalise isikhwama ngomkhiqizo, bese isivala, konke ngendlela eqondile, ngesivinini esingafika kumasaka angu-300 ngomzuzu. Kodwa kunokuningi kukho kunalokho.
1. Ifilimu Ezokuthutha Nokuzothula
Imishini yokupakisha eqondile isebenzisa ishidi elilodwa lezinto zefilimu ezigoqelwe endaweni ephakathi, ngokuvamile ebizwa ngokuthi i-rollstock. Ubude obuqhubekayo bezinto zokupakisha bubizwa ngokuthi iwebhu yefilimu. Lezi zinto zingahluka kusuka ku-polyethylene, i-cellophane laminates, i-foil laminates kanye nama-laminates wephepha. Umqulu wefilimu ubekwe phezu komhlangano wokuphotha ngemuva komshini.
Lapho umshini wokupakisha we-VFFS usebenza, ifilimu ivamise ukukhishwa kumqulu ngamabhande okuthutha amafilimu, abekwe eceleni kweshubhu elenzayo elitholakala ngaphambili komshini. Le ndlela yokuthutha iyona esetshenziswa kakhulu. Kwamanye amamodeli, imihlathi evala uphawu ngokwayo ibamba ifilimu futhi iyidonsele phansi, ithuthe ngomshini wokupakisha ngaphandle kokusebenzisa amabhande.
Isondo lokuphumuza indawo elishayelwa ngemoto ozikhethela lona (ukukhulula amandla) lingase lifakwe ukuze kushayelwe i-roll yefilimu njengosizo ekushayeleni amabhande amabili okuthutha amafilimu. Lolu khetho luthuthukisa inqubo yokuqaqa, ikakhulukazi uma ama-rolls efilimu esindayo.
2. Ukushuba Kwefilimu
I-vffs-packaging-machine-film-uwind-and-feedingPhakathi ukuqaqa, ifilimu ayilimali emgqeni futhi idlula ingalo yomdansi okuyingalo ye-pivot enesisindo etholakala ngemuva komshini wokupakisha we-VFFS. Ingalo ihlanganisa uchungechunge lwamarola. Njengoba ifilimu ithutha, ingalo iya phezulu naphansi ukuze igcine ifilimu ingaphansi kokucindezeleka. Lokhu kuqinisekisa ukuthi ifilimu ngeke izule ngapha nangapha njengoba ihamba.
3. Ukuphrinta Ongakukhetha
Ngemva komdansi, ifilimu ibe isihamba ngeyunithi yokunyathelisa, uma ifakiwe. Amaphrinta angase abe uhlobo olushisayo noma lwe-ink-jet. Iphrinta ibeka amadethi/amakhodi afiswayo kufilimu, noma ingase isetshenziselwe ukubeka izimpawu zokubhalisa, imifanekiso, noma amalogo efilimu.
4. Ukulandelela Amafilimu kanye Nokuma
i-vffs-packaging-machine-film-tracking-positioningUma ifilimu isidlulile ngaphansi kwephrinta, idlula i-photo-eye yokubhalisa. Iso lesithombe sokubhaliswa lithola uphawu lokubhalisa efilimini ephrintiwe bese kuthi ngokulandelayo, lilawule amabhande okudonsela phansi axhumene nefilimu eshubhuni elenzayo. Iso lesithombe sokubhaliswa ligcina ifilimu ibekwe ngendlela efanele ukuze ifilimu isikwe endaweni efanele.
Okulandelayo, ifilimu idlula izinzwa zokulandelela ifilimu ezithola indawo yefilimu njengoba ihamba emshinini wokupakisha. Uma izinzwa zithola ukuthi unqenqema lwefilimu luyasuka endaweni evamile, kukhiqizwa isignali ukuhambisa i-actuator. Lokhu kubangela ukuthi yonke inqola yefilimu igudlukele ohlangothini olulodwa noma kolunye njengoba kudingeka ukubuyisela unqenqema lwefilimu endaweni efanele.
5. Ukwakhiwa Kwesikhwama
i-vffs-packaging-machine-forming-tube-assemblyKusuka lapha, ifilimu ingena ekuhlanganiseni kwamashubhu okwenza. Njengoba i-crests ihlombe (ikholomu) ku-tube yokwakha, igoqwe eduze kwe-tube ukuze umphumela wokugcina ube ubude befilimu enemiphetho emibili yangaphandle yefilimu ehambisanayo. Lesi yisiqalo senqubo yokwenza isikhwama.
Ishubhu lokwakha lingasethwa ukwenza i-lap seal noma i-fin seal. I-lap seal idlulela emaphethelweni amabili angaphandle efilimu ukuze kwakhe uphawu oluyisicaba, kuyilapho i-fin seal ishada nengaphakathi lamaphethelo amabili angaphandle efilimu ukuze kwakhe uphawu oluphumela ngaphandle, njengephiko. I-lap seal ngokuvamile ibhekwa njengejabulisa kakhulu futhi isebenzisa impahla encane kune-fin seal.
Isishumeki esijikelezayo sibekwe eduze kwehlombe (collar) leshubhu elibunjiweyo. Ifilimu enyakazayo exhumene nesondo lesishumeli sekhodi iyayishayela. Ukushaya kwenhliziyo kukhiqizwa kubo bonke ubude bokunyakaza, futhi lokhu kudluliselwa ku-PLC (isilawuli se-logic esihlelekayo). Isethingi yobude besikhwama isethwe esikrinini se-HMI (umshini womuntu) njengenombolo futhi uma lesi silungiselelo sesifinyelelwe izitobhi zefilimu ziyama (Emishinini enyakazayo yezikhawu kuphela. Imishini enyakazayo ayimi.)
Ifilimu idonswa phansi ngamagiya amabili amabhande adonsa amabhande okudonsela phansi atholwe nhlangothi zombili zeshubhu eyakhayo. Amabhande adonsela phansi asebenzisa ukumuncwa kwe-vacuum ukuze abambe ifilimu yokupakisha angashintshwa esikhundleni samabhande okukhuhlana uma efunwa. Amabhande e-Friction ngokuvamile anconywa emikhiqizweni enothuli njengoba ehlangabezana nokuguga okuncane.
6. Ukugcwaliswa kwesikhwama nokuvala uphawu
I-VFFS-packaging-machine-horizontal-seal-barManje ifilimu izoma kafushane (emishinini yokupakisha enyakazayo) ukuze isikhwama esakhiwe sithole uphawu lwaso olume mpo. Ibha yophawu eqondile, eshisayo, iya phambili futhi ithintana nokugqagqana okuqondile kwefilimu, ihlanganisa izendlalelo zefilimu.
Emishinini yokupakisha ye-VFFS enyakazayo, indlela yokuvala eqondile ihlala ixhumene nefilimu ngokuqhubekayo ukuze ifilimu ingadingi ukuma ukuze ithole umthungo wayo ome mpo.
Okulandelayo, iqoqo lemihlathi yokuvala evundlile eshisayo iyahlangana ukuze yenze uphawu olungaphezulu lwesikhwama esisodwa kanye nophawu olungezansi lwesikhwama esilandelayo. Emishinini yokupakisha ye-VFFS yesikhashana, ifilimu iyama ukuze ithole uphawu lwayo oluvundlile emihlathini enyakazayo ngokuvala okuvulekile. Emishinini yokupakisha eqhubekayo, imihlathi inyakaza ibheke phansi futhi ivuleke ivale ukuze ivale ifilimu njengoba ihamba. Eminye imishini enyakazayo eqhubekayo ize ibe namasethi amabili emihlathi yokuvala ukuze ijubane elengeziwe.
Inketho yohlelo 'lokuvalwa okubandayo' ama-ultrasonics, avame ukusetshenziswa ezimbonini ezinemikhiqizo engezwani nokushisa noma engcolile. Ukuvalwa kwe-Ultrasonic kusebenzisa ukudlidliza ukuze kubangele ukungqubuzana ezingeni lamangqamuzana akhiqiza ukushisa kuphela endaweni ephakathi kwezingqimba zefilimu.
Ngenkathi imihlathi yokuvala ivaliwe, umkhiqizo opakishwayo wehliswa phansi maphakathi neshubhu lokubumba elingenalutho bese ugcwaliswa esikhwameni. Imishini yokugcwalisa efana nesikali esinamakhanda amaningi noma isigcwalisi se-auger inesibopho sokukala okufanele kanye nokukhishwa kwenani elihlukile lomkhiqizo okufanele lifakwe esikhwameni ngasinye. Lawa ma-filler awayona ingxenye ejwayelekile yomshini wokupakisha we-VFFS futhi kufanele athengwe ngaphezu komshini ngokwawo. Amabhizinisi amaningi ahlanganisa i-filler nomshini wabo wokupakisha.
7. Ukukhipha Isikhwama
i-vffs-packaging-machine-dischargeNgemva kokuba umkhiqizo usukhishelwe esikhwameni, ummese obukhali ngaphakathi kwe-heat seal imihlathi uya phambili futhi usike isikhwama. Umhlathi uyavuleka bese kwehla isikhwama esipakishiwe. Lesi ukuphela komjikelezo owodwa emshinini wokupakisha oqondile. Ngokuya ngomshini nohlobo lwesikhwama, okokusebenza kwe-VFFS kungaqeda phakathi kuka-30 no-300 wale mijikelezo ngomzuzu.
Isikhwama esiqediwe singakhishelwa esitshalweni noma ku-conveyor futhi sithuthelwe emishinini ephansi efana nezikali zamasheke, imishini ye-x-ray, ukupakisha amakesi, noma impahla yokupakisha amabhokisi.
