Iifom zokupakisha ezithe nkqo zizalise itywina (VFFS) oomatshini bokupakishazisetyenziswa phantse kuwo onke amashishini namhlanje, ngesizathu esivakalayo: Zizizisombululo zokupakishwa ezikhawulezayo, ezinoqoqosho ezigcina indawo yomgangatho wezityalo.
Nokuba umtsha kumatshini wokupakisha okanye sele uneenkqubo ezininzi, amathuba okuba unomdla wokuba zisebenza njani na. Kweli nqaku, sihamba ngendlela ifom ethe nkqo yokuzalisa umatshini wokutywina ujika umqulu wefilimu yokupakisha kwingxowa egqityiweyo esele ilungile.
Oomatshini bokupakisha abalula, abathe nkqo baqala ngomqulu omkhulu wefilimu, bawufake kwimilo yengxowa, bagcwalise ingxowa ngemveliso, baze bayitywine yonke into ngendlela ethe nkqo, ngesantya esifikelela kwiingxowa ezingama-300 ngomzuzu. Kodwa kukho okungakumbi kunoko.
1. UThutho lweFilimu & Ukuphumla
Oomatshini bokupakisha abathe nkqo basebenzisa iphepha elinye lezinto zefilimu ezijikelezwe kumbindi, odla ngokubizwa ngokuba yi-rollstock. Ubude obuqhubekayo bezinto zokupakisha zibizwa ngokuba yiwebhu yefilimu. Esi sixhobo sinokuhluka kwi-polyethylene, i-cellophane laminates, i-foil laminates kunye ne-laminates yephepha. Umqulu wefilimu ubekwe kwi-spindle assembly ngasemva komatshini.
Xa umatshini wokupakisha we-VFFS usebenza, ifilimu idla ngokutsalwa kwi-roll ngamabhanti okuthutha ifilimu, abekwe kwicala lombhobho wokwenza obekwe phambi komatshini. Le ndlela yothutho yeyona isetyenziswa kakhulu. Kweminye imizekelo, imihlathi yokutywina ngokwayo ibamba ifilimu kwaye idwebe phantsi, ithuthe ngomatshini wokupakisha ngaphandle kokusetyenziswa kwamabhande.
Ivili lokuthomalalisa eliqhutywa ngemoto elinokuzikhethela (ukukhulula amandla) linokufakelwa ukuqhuba umqulu wefilimu njengoncedo ekuqhubeni amabhanti amabini othutho lwefilimu. Olu khetho luphucula inkqubo yokukhulula, ngakumbi xa iifilimu zihamba nzima.
2. Uxinzelelo lwefilimu
I-vffs-packaging-machine-film-unwind-and-feedingNgexesha lokukhulula, ifilimu ayibonakalisi kumqulu kwaye idlule phezu kwengalo yomdanisi eyingalo yepivot enobunzima ebekwe ngasemva kumatshini wokupakisha weVFFS. Ingalo idibanisa uluhlu lweerola. Njengoko ifilimu ihambisa, ingalo ihla inyuka ukuze igcine ifilimu iphantsi koxinzelelo. Oku kuqinisekisa ukuba ifilimu ayiyi kubhadula ukusuka kwelinye icala ukuya kwelinye njengoko ihamba.
3. Ushicilelo ngokuzikhethela
Emva komdanisi, ifilimu ke ihamba ngeyunithi yokushicilela, ukuba enye ifakwe. Izishicileli zinokuba luhlobo lwe-thermal okanye lwe-ink-jet. Umshicileli ubeka imihla/iikhowudi ezifunekayo kwifilimu, okanye isenokusetyenziswa ukubeka amanqaku obhaliso, iigrafiki, okanye iilogo kwifilimu.
4. Ukulandelela ifilim kunye nokumiswa
I-vffs-packaging-machine-film-tracking-positioningEmva kokuba ifilimu idlulile phantsi komshicileli, idlula kwi-photo-eye yokubhalisa. Iso lesithombe sokubhalisa libona uphawu lokubhalisa kwifilimu eprintiweyo kwaye ngokulandelayo, ilawula amabhanti okudonsa ngokudibanisa nefilimu kwi-tube yokwenza. I-photo-eye yokubhalisa igcina ifilimu ibekwe ngokuchanekileyo ukuze ifilimu inqunywe kwindawo efanelekileyo.
Okulandelayo, ifilimu ihamba ngaphaya kwezinzwa zomkhondo wefilimu ezibona indawo yefilimu njengoko ihamba kumatshini wokupakisha. Ukuba abenzi boluvo babona ukuba umda wefilimu uyaguquka uphume kwindawo eqhelekileyo, umqondiso uyaveliswa ukuhambisa i-actuator. Oku kubangela ukuba yonke inqwelo yefilimu itshintshele kwelinye icala okanye kwelinye njengoko kuyimfuneko ukubuyisela umda wefilimu kwindawo echanekileyo.
5. Ukwenziwa kweengxowa
I-vffs-packaging-machine-forming-tube-assembly Ukusuka apha, ifilimu ingena kwindibano ye-tube yokubumba. Njengoko i-crests ihlombe (i-collar) kwi-tube yokwenza i-tube, igoqwe malunga ne-tube ukwenzela ukuba umphumo wokugqibela ubude befilimu kunye nemiphetho yangaphandle yefilimu edibanisayo. Esi sisiqalo senkqubo yokwenza ingxowa.
Umbhobho wokwenza umbhobho unokusekwa ukwenza i-lap seal okanye i-fin seal. Itywina ligqithe imiphetho emibini yangaphandle yefilim ukwenza itywina elisicaba, ngelixa itywina litshatisa izibilini zangaphandle zefilimu ukwenza itywina eliphuma ngaphandle, njengephiko. I-lap seal ithathwa ngokuba ithandeka ngakumbi kwaye isebenzisa imathiriyeli encinci kune-fin seal.
I-encoder ejikelezayo ibekwe kufuphi negxalaba (ikhola) yetyhubhu yokwenza. Ifilimu ehambayo enxibelelana nevili leencoder iyayiqhuba. I-pulse iveliswa kuyo yonke ubude bentshukumo, kwaye oku kudluliselwa kwi-PLC (umlawuli wengqiqo ecwangcisiweyo). Isicwangciso sobude bebhegi sisetwe kwisikrini se-HMI (ujongano lomatshini woluntu) njengenani kwaye emva kokuba olu seto lufikelelwe indawo yokumisa ifilim (Kumatshini oshukumayo wethutyana kuphela. Oomatshini abashukumayo abaqhubekayo abamisi.)
Ifilimu itsalwa phantsi ziinjini ezimbini zegiya eziqhuba amabhanti okutsalela ezantsi okukhuhlana abekwe macala omabini etyhubhu yokwenza. Ukutsalela phantsi amabhanti asebenzisa ivacuum ukufunxa ukubamba ifilim yokupakisha inokufakwa endaweni yamabhanti okukhuhlana ukuba uyafunwa. Iibhanti zefriction zihlala zinconywa kwiimveliso ezinothuli njengoko zifumana ukuguga okuncinci.
6. Ukuzaliswa kwengxowa kunye nokutywinwa
Umatshini wokupakisha we-VFFS-horizontal-seal-barsNgoku ifilimu iza kunqumama ngokufutshane (kumatshini wokupakisha oshukumayo onyakazayo) ukuze ingxowa eyenziweyo ikwazi ukufumana itywina layo elithe nkqo. Ibha yokutywina ethe nkqo, eshushu, iqhubela phambili kwaye inxibelelana ngokugqithela ngokuthe nkqo kwifilimu, idibanisa iileya zefilimu kunye.
Kwisixhobo sokupakisha se-VFFS esiqhubekayo, indlela yokutywina ethe nkqo ihlala inxibelelana nefilimu ngokuqhubekayo ukuze ifilimu ingabikho mfuneko yokuba ime ukuze ifumane umthungo wayo othe nkqo.
Okulandelayo, iseti yemihlathi eshushu yokutywina ethe tyaba idibana ukwenza itywina eliphezulu lengxowa enye kunye netywina elisezantsi lebhegi elandelayo. Ngoomatshini bokupakisha be-VFFS bethutyana, ifilimu iyama ukuze ifumane itywina layo elithe tyaba kwimihlathi ehamba ngentshukumo evulekileyo. Kumatshini wokupakisha oqhubekayo, imihlathi ngokwayo ihambela phezulu-ezantsi kwaye ivuleke ivale izindululo ukutywina ifilimu njengoko ishukuma. Abanye oomatshini abashukumayo abaqhubekayo bade babe neeseti ezimbini zemihlathi yokutywina ngesantya esongezelelweyo.
Inketho yenkqubo 'yokutywinwa okubandayo' yi-ultrasonics, ehlala isetyenziswa kumashishini anemveliso engangenwa bubushushu okanye emdaka. Ukutywinwa kwe-Ultrasonic kusebenzisa ii-vibrations ukwenza ukungqubuzana kwinqanaba le-molecular eyenza ubushushu kuphela kwindawo phakathi kweengqimba zefilimu.
Ngelixa imihlathi yokutywina ivaliwe, imveliso epakishwayo ithotywa phantsi embindini wombhobho wokwenza umngxuma kwaye izaliswe kwingxowa. Isixhobo sokuzalisa esifana nesikali seentloko ezininzi okanye isigcwali se-auger sinoxanduva lomlinganiselo ochanekileyo kunye nokukhululwa komthamo ocacileyo wemveliso oza kuwiswa kwingxowa nganye. Ezi zihluzi aziyonxalenye eqhelekileyo yomatshini wokupakisha weVFFS kwaye kufuneka uthenge ukongeza kumatshini ngokwawo. Uninzi lwamashishini adibanisa i-filler kunye nomatshini wabo wokupakisha.
7. Ukukhutshwa kwengxowa
I-vffs-packaging-machine-dischargeEmva kokuba imveliso ikhutshwe kwisikhwama, imela ebukhali ngaphakathi kwe-heat seal emihlathini iqhubela phambili kwaye inqumle isikhwama. Umhlathi uyavuleka kwaye ingxowa epakishiweyo iyawa. Esi sisiphelo somjikelo omnye kumatshini wokupakisha othe nkqo. Kuxhomekeke kumatshini kunye nohlobo lwebhegi, izixhobo zeVFFS zinokugqiba phakathi kwama-30 kunye nama-300 ale mijikelo ngomzuzu.
Ibhegi egqityiweyo inokukhutshelwa kwisitya okanye kwisixhobo sokuhambisa kwaye ithuthwe isiwe kwisixhobo esisezantsi esifana nezixhobo zokukala iitshekhi, oomatshini be-x-reyi, ukupakisha ikesi, okanye izixhobo zokupakisha iibhokisi.
