Makina Osindikizira a CI Flexo
Makina osindikizira a CI (Central Impression) flexo amagwiritsa ntchito ng'oma imodzi yayikulu kuti agwire zinthuzo mosasunthika pamene mitundu yonse ikusindikizidwa mozungulira. Kapangidwe kameneka kamasunga mphamvu yolimba komanso kamapereka kulondola kwabwino kwambiri pakulembetsa, makamaka pa mafilimu omwe amatambasuka mosavuta.
Imagwira ntchito mwachangu, imawononga zinthu zochepa, ndipo imapanga zotsatira zabwino kwambiri zosindikizidwa—zabwino kwambiri pokonza ma CD apamwamba komanso kugwiritsa ntchito molondola kwambiri.
Makina Osindikizira a Flexo Type Stack Type
Chosindikizira cha flexo chokhazikika chimakhala ndi mtundu uliwonse wokonzedwa molunjika, ndipo siteshoni iliyonse imatha kusinthidwa yokha. Izi zimapangitsa kuti zikhale zosavuta kugwiritsa ntchito zipangizo zosiyanasiyana komanso kusintha kwa ntchito. Chimagwira ntchito bwino pamitundu yosiyanasiyana ya zinthu ndipo ndi chothandiza makamaka posindikiza mbali ziwiri.
Ngati mukufuna makina osinthasintha komanso otsika mtengo ogwirira ntchito zolongedza tsiku ndi tsiku, makina osindikizira a stack flexo ndi chisankho chothandiza komanso chodalirika.
Kaya ndi makina osindikizira a CI flexo kapena makina osindikizira a flexo amtundu wa stack, kulakwitsa kulemba mitundu kungachitike, zomwe zingakhudze momwe mtundu umagwirira ntchito komanso mtundu wa kusindikiza kwa chinthu chomaliza. Masitepe asanu otsatirawa amapereka njira yokhazikika yothetsera mavuto ndikuthetsa vutoli.
1. Yang'anani Kukhazikika kwa Makina
Kulembetsa molakwika nthawi zambiri kumabwera chifukwa cha kuwonongeka kwa makina kapena kutayirira. Pa makina osindikizira a stack flexo, ndikofunikira kuyang'ana magiya, mabearing, ndi malamba oyendetsa omwe amalumikiza chipangizo chilichonse chosindikizira, kuonetsetsa kuti palibe play kapena offset yomwe ingasokoneze kulinganiza.
Makina osindikizira apakati nthawi zambiri amakhala ndi kulembetsa kokhazikika chifukwa mitundu yonse imasindikizidwa motsutsana ndi ng'oma imodzi yokha. Ngakhale zili choncho, kulondola kumadalirabe kuyika silinda ya mbale yoyenera ndikusunga mphamvu yokhazikika ya ukonde - ngati chilichonse chikuyenda, kukhazikika kwa kulembetsa kudzachepa.
Malangizo:Nthawi iliyonse pamene ma plate asinthidwa kapena makina akhala osagwira ntchito kwa kanthawi, tembenuzani chipangizo chilichonse chosindikizira ndi dzanja kuti mumve ngati pali kukana kulikonse kwachilendo. Mukamaliza kusintha, yambani kusindikiza pa liwiro lotsika ndikuwona zizindikiro zolembetsa. Izi zimathandiza kutsimikizira ngati kulinganiza kumakhalabe kofanana musanapititse patsogolo liwiro lonse lopanga.
2. Konzani Kugwirizana kwa Substrate
Zinthu monga filimu, mapepala, ndi zinthu zopanda nsalu zimasiyana ndi kupsinjika, ndipo kusiyana kumeneku kungayambitse kusintha kwa kulembetsa panthawi yosindikiza. Makina osindikizira a CI flexographic nthawi zambiri amakhala ndi kupsinjika kokhazikika ndipo motero ndi oyenera kugwiritsa ntchito mafilimu omwe amafunikira kulondola kwambiri. Mosiyana ndi zimenezi, makina osindikizira a flexo nthawi zambiri amafunika kukonza bwino kwambiri makonda a kupsinjika kuti agwirizane bwino.
Malangizo:Mukawona kuti zinthuzo zikutambasuka kapena kuchepa kwambiri, chepetsani kupsinjika kwa ukonde. Kupsinjika kochepa kungathandize kuchepetsa kusintha kwa mawonekedwe ndikuchepetsa kusinthasintha kwa kulembetsa.
3. Kugwirizana kwa Mbale ndi Mpukutu wa Anilox
Makhalidwe a mbale—monga makulidwe, kuuma, ndi kulondola kwa zilembo—zimakhudza mwachindunji magwiridwe antchito olembetsa. Kugwiritsa ntchito mbale zowoneka bwino kwambiri kungathandize kuwongolera kuchuluka kwa madontho ndikuwonjezera kukhazikika. Kuchuluka kwa mizere ya anilox kuyeneranso kufananizidwa mosamala ndi mbale: kuchuluka kwa mizere komwe kuli kokwera kwambiri kungachepetse kuchuluka kwa inki, pomwe kuwerengera komwe kuli kotsika kwambiri kungayambitse inki yochulukirapo ndi kutayikira, zomwe zonsezi zingakhudze mwachindunji kulinganiza kolembetsa.
Malangizo:Ndikoyenera kwambiri kuwongolera kuchuluka kwa mzere wa anilox roller pa 100 - 1000 LPI. Onetsetsani kuti kuuma kwa plate kumakhala kofanana pa mayunitsi onse kuti mupewe kukulitsa kusiyana kumeneku.
4. Sinthani Kupanikizika kwa Kusindikiza ndi Dongosolo la Inki
Ngati kupanikizika kwa chizindikiro kwakwera kwambiri, ma plate osindikizira amatha kusokonekera, ndipo vutoli limapezeka kwambiri pamakina osindikizira a flexo amtundu wa stack, pomwe siteshoni iliyonse imayika kupanikizika payokha. Ikani kupanikizika kwa chipangizo chilichonse padera ndipo gwiritsani ntchito zochepa zomwe zimafunika kuti chithunzi chisamutsidwe bwino. Khalidwe lokhazikika la inki limagwiranso ntchito yofunika kwambiri pakuwongolera kulembetsa. Yang'anani ngodya ya tsamba la dokotala ndikusunga kukhuthala koyenera kwa inki kuti mupewe kufalikira kwa inki kosagwirizana, komwe kungayambitse kusintha kwa kulembetsa komweko.
Malangizo:Pa makina osindikizira a mtundu wa stack ndi CI flexographic, njira yaifupi ya inki komanso kusamutsa inki mwachangu kumawonjezera chidwi cha mawonekedwe ouma. Yang'anirani liwiro la kuumitsa panthawi yopanga, ndipo yambitsani retarder ngati inki yayamba kuuma mwachangu kwambiri.

5. Gwiritsani ntchito Zida Zodzilembetsera Zokha ndi Zolipirira
Makina ambiri osindikizira amakono a flexographic ali ndi zinthu zolembetsa zokha zomwe zimakonza kulinganiza nthawi yeniyeni pamene kupanga kukuchitika. Ngati mavuto olinganiza akadalipo pambuyo pa kusintha kwamanja, tengani nthawi yowunikiranso zolemba zakale za ntchito. Kuyang'ana mmbuyo deta yakale yopanga kumatha kupeza machitidwe obwerezabwereza kapena kusiyana kokhudzana ndi nthawi komwe kukuwonetsani chomwe chimayambitsa, kukuthandizani kupanga kusintha kokhazikika komanso kogwira mtima.
Malangizo:Kwa makina osindikizira omwe akhala akugwira ntchito kwa nthawi yayitali, ndikofunikira kuyang'ana mzere wonse wa makina osindikizira nthawi ndi nthawi. Gawoli ndilofunika kwambiri pa makina osindikizira amtundu wa stack flexo, chifukwa siteshoni iliyonse imagwira ntchito yokha ndipo kulembetsa kosalekeza kumadalira kuwasunga molingana ngati dongosolo logwirizana.
Mapeto
Kaya ndi makina osindikizira a flexographic opangidwa ndi central impression kapena makina osindikizira a flexo amtundu wa stack, vuto lolembetsa mitundu nthawi zambiri limayamba chifukwa cha kuyanjana kwa makina, zinthu ndi njira zosiyanasiyana, osati chifukwa cha chinthu chimodzi. Kudzera mu kuthetsa mavuto mwadongosolo komanso kukonza mosamala, tikukhulupirira kuti mutha kuthandiza makina osindikizira a flexographic kuti ayambirenso kupanga ndikukonza kukhazikika kwa zida kwa nthawi yayitali.
