Makina onyamula a Vertical form fill seal (VFFS).amagwiritsidwa ntchito pafupifupi m'makampani aliwonse masiku ano, pazifukwa zomveka: Ndi njira zophatikizira zachangu, zotsika mtengo zomwe zimasunga malo amtengo wapatali a zomera.
Kaya ndinu watsopano pamakina olongedza kapena muli ndi makina angapo, mwayi ndiwe wofuna kudziwa momwe amagwirira ntchito.M'nkhaniyi, tikuyenda momwe makina oyimirira odzaza makina osindikizira amasinthira mpukutu wa filimu yolongedza kukhala thumba lokonzekera mashelufu.
Makina onyamula osavuta, oyimirira amayambira ndi mpukutu waukulu wa filimu, kupanga mawonekedwe a thumba, mudzaze thumba ndi mankhwala, ndikusindikiza, zonse molunjika, pa liwiro la matumba 300 pamphindi.Koma pali zambiri kwa izo kuposa izo.
1. Mafilimu Oyendetsa & Kupumula
Makina onyamula oyimirira amagwiritsa ntchito pepala limodzi lazinthu zamakanema zozungulira pachimake, zomwe nthawi zambiri zimatchedwa rollstock.Kutalika kosalekeza kwa zinthu zonyamula kumatchedwa ukonde wa kanema.Zinthuzi zimatha kusiyana ndi polyethylene, cellophane laminates, zojambulazo za laminate ndi mapepala a mapepala.Mpukutu wa filimuyo umayikidwa pa msonkhano wa spindle kumbuyo kwa makina.
Makina onyamula a VFFS akamagwira ntchito, filimuyo nthawi zambiri imakokedwa ndi malamba onyamula filimu, omwe amayikidwa pambali pa chubu chopanga chomwe chili kutsogolo kwa makinawo.Njira yoyenderayi ndiyomwe imagwiritsidwa ntchito kwambiri.Pazitsanzo zina, nsagwada zosindikizira zokha zimagwira filimuyo ndikuyikokera pansi, ndikuyiyendetsa pamakina oyikamo popanda kugwiritsa ntchito malamba.
Mawilo opumulira omwe amayendetsedwa ndi injini (wotulutsa mphamvu) atha kuyikidwa kuti ayendetse mpukutu wa filimuyo ngati chothandizira kuyendetsa malamba awiriwa.Njirayi imathandizira kumasula, makamaka pamene filimuyi imakhala yolemetsa.
2. Kuvuta kwa Mafilimu
vffs-packaging-machine-film-unwind-and-feedingPakumasula, filimuyi imamasulidwa kuchokera pampukutu ndikudutsa pa mkono wovina womwe ndi wolemera mkono wopindika womwe uli kumbuyo kwa makina osindikizira a VFFS.Nkhonoyi imakhala ndi ma roller angapo.Pamene filimuyo imayendetsa, mkono umayenda mmwamba ndi pansi kuti filimuyo ikhale yovuta.Izi zimatsimikizira kuti filimuyo sidzayendayenda uku ndi uku pamene ikuyenda.
3. Kusindikiza Mwasankha
Pambuyo pa wovina, filimuyo imadutsa muzitsulo zosindikizira, ngati imodzi yaikidwa.Zosindikiza zitha kukhala zamtundu wamafuta kapena inki-jet.Osindikiza amaika masiku/makhodi omwe amafunidwa pafilimuyo, kapena angagwiritsidwe ntchito kuyika zilembo, zithunzi, kapena ma logo pafilimuyo.
4. Kutsata Mafilimu ndi Maonekedwe
vffs-packaging-machine-film-tracking-positioningFilimuyo ikadutsa pansi pa chosindikizira, imadutsa pazithunzi zolembetsa.Diso lachithunzi cholembera limazindikira chizindikiro cholembera pa filimu yosindikizidwa ndipo kenako, amawongolera malamba okokera pansi pokhudzana ndi filimuyo pa chubu chopanga.Kulembetsa chithunzi-diso kumasunga filimuyo moyenera kotero kuti filimuyo idzadulidwa pamalo oyenera.
Kenako, filimuyo imadutsa m'masensa akulondolera filimu omwe amazindikira malo omwe filimuyo ikudutsa m'makina olongedza.Ngati masensa awona kuti m'mphepete mwa filimuyo mwachoka pamalo abwino, chizindikiro chimapangidwa kuti chisunthire chowongolera.Izi zimapangitsa kuti chonyamulira chonse cha filimuyo chisunthike mbali imodzi kapena imzake ngati pakufunika kubweretsanso m'mphepete mwa filimuyo pamalo oyenera.
5. Kupanga Chikwama
vffs-packaging-machine-forming-chubu-assemblyKuchokera apa, filimuyi ikulowa mumsonkhano wopangira chubu.Pamene imagwedeza phewa (kolala) pa chubu chopanga, imakulungidwa mozungulira chubu kotero kuti mapeto ake ndi kutalika kwa filimu yokhala ndi mbali ziwiri zakunja za filimuyo zomwe zikudutsana.Ichi ndi chiyambi cha thumba kupanga ndondomeko.
Chojambulacho chikhoza kukhazikitsidwa kuti chisindikize chisindikizo kapena chisindikizo.Chisindikizo cha lap chimadutsa m'mbali ziwiri zakunja za filimuyo kuti apange chisindikizo chathyathyathya, pomwe chosindikizira chimakwirira mkati mwa m'mphepete mwa filimuyo kuti apange chisindikizo chomwe chimatuluka, ngati chipsepse.Chisindikizo cha lap nthawi zambiri chimatengedwa kuti ndichokongola kwambiri ndipo chimagwiritsa ntchito zinthu zochepa kuposa chisindikizo.
Chotsekera chozungulira chimayikidwa pafupi ndi phewa (kolala) ya chubu chopanga.Filimu yosuntha yokhudzana ndi gudumu la encoder imayendetsa.Kugunda kumapangidwa kutalika kulikonse koyenda, ndipo izi zimasamutsidwa ku PLC (programmable logic controller).Kutalika kwa thumba kumayikidwa pa sikirini ya HMI (mawonekedwe a makina a anthu) ngati nambala ndipo izi zikafika, zoyendera zamakanema zimayima (Pamakina oyenda pang'onopang'ono okha. Makina oyenda mosalekeza samayima.)
Kanemayo amakokedwa ndi magiya awiri omwe amayendetsa malamba okokera pansi omwe ali mbali zonse za chubu chopangira.Kokani malamba omwe amagwiritsa ntchito vacuum suction kuti agwire filimu yolongedza amatha kulowetsa malamba ngati angafune.Malamba a friction nthawi zambiri amalimbikitsidwa pazinthu zafumbi chifukwa savala kwambiri.
6. Kudzaza Chikwama ndi Kusindikiza
VFFS-packaging-machine-horizontal-seal-barsTsopano filimuyi idzayima pang'ono (pamakina opakira oyenda pang'onopang'ono) kuti chikwama chopangidwa chilandire chisindikizo chake choyimirira.Chosindikizira choyima, chomwe chimakhala chotentha, chimapita patsogolo ndikulumikizana ndi kuphatikizika koyima pafilimuyo, kulumikiza zigawo za filimuyo pamodzi.
Pazida zomangira za VFFS mosalekeza, makina osindikizira oyimirira amakhalabe olumikizana ndi filimuyo mosalekeza kotero kuti filimuyo sayenera kuyimitsa kuti ilandire msoko wake woyima.
Kenaka, nsagwada zomata zotentha zopingasa zimasonkhana pamodzi kuti zisindikize pamwamba pa thumba limodzi ndi chisindikizo chapansi cha thumba lotsatira.Pamakina apakatikati a VFFS, filimuyo imayima kuti ilandire chisindikizo chake chopingasa kuchokera ku nsagwada zomwe zimayenda motseka.Pamakina opaka mosalekeza, nsagwadazo zimasunthira mmwamba-pansi ndikutsegula-kutseka kuti asindikize filimuyo pamene ikuyenda.Makina ena oyenda mosalekeza amakhala ndi ma seti awiri a nsagwada zomata kuti awonjezere liwiro.
Njira ya 'ozizira kusindikiza' dongosolo ndi ultrasonics, nthawi zambiri ntchito m'mafakitale ndi kutentha tcheru kapena chisokonezo mankhwala.Kusindikiza kwa akupanga kumagwiritsa ntchito kugwedezeka kuti kupangitse kukangana pamlingo wa molekyulu womwe umapangitsa kutentha kokha pakati pa zigawo za filimu.
Pamene nsagwada zosindikizira zatsekedwa, chinthu chomwe chikuyikidwacho chimatsitsidwa pansi pakati pa dzenje lopanga chubu ndikudzaza m'thumba.Chida chodzaza ngati sikelo ya mitu yambiri kapena chojambulira cha auger ndichomwe chimayang'anira kuyeza koyenera ndikutulutsa kuchuluka kwazinthu zomwe ziyenera kuponyedwa m'thumba lililonse.Zodzaza izi si gawo lokhazikika pamakina onyamula a VFFS ndipo ziyenera kugulidwa kuwonjezera pa makinawo.Mabizinesi ambiri amaphatikiza chodzaza ndi makina awo onyamula.
7. Kutulutsa Thumba
vffs-packaging-machine-discharge Pambuyo potulutsidwa m'thumba, mpeni wakuthwa mkati mwa nsagwada zosindikizira kutentha umapita patsogolo ndikudula thumba.Chibwano chimatseguka ndipo chikwama chopakidwacho chimatsika.Uku ndi kutha kwa mkombero umodzi pamakina oyimirira olongedza.Kutengera makina ndi mtundu wa thumba, zida za VFFS zimatha kumaliza pakati pa 30 ndi 300 pazozungulira izi pamphindi.
Chikwama chomalizidwacho chikhoza kutulutsidwa muchotengera kapena pa chotengera ndi kutumizidwa ku zida zotsikirako monga zoyezera cheke, makina a x-ray, kulongedza zingwe, kapena zida zolongedzera makatoni.
