Momwe mungapangire roller ya aniloxmakina osindikizira a flexographic

Makina ambiri osindikizira onse a m'munda, mzere, ndi chithunzi chopitilira. Pofuna kukwaniritsa zosowa za zinthu zosiyanasiyana zosindikizira, ogwiritsa ntchito sayenera kugwiritsa ntchito makina osindikizira a flexo okhala ndi makina osindikizira ochepa okhala ndi machitidwe ochepa ozungulira. Mwachitsanzo, tengani makina osindikizira a flexo a unit yopapatiza, omwe ndi 6+1, omwe ndi magulu 6 amitundu yosindikizira yamitundu yambiri, unit yomaliza ikhoza kusindikizidwa ndi UV glazing.

Tikupangira kuti posindikiza mizere yosapitirira 150, makina osindikizira a 6+1 awa a flexo ayenera kukhala ndi ma rollers 9 a anilox. Ma PC anayi a ma rollers a anilox okhala ndi makulidwe a 2.3BCM (1 biliyoni cubic micron/inch) ndi 60° amagwiritsidwa ntchito posindikiza magawo. Ma PC atatu a mizere 360 ​​~ 400, BCM6.0, 60° roller yosindikizira m'munda; Ma PC awiri a mizere 200, BCM15 kapena kuposerapo, 60° roller yosindikizira golide ndi glazing. Ngati mugwiritsa ntchito mafuta owunikira ochokera m'madzi, muyenera kusankha roll ya mizere 360, kuti gawo la mafuta likhale lochepa pang'ono, lisakhudze liwiro losindikiza chifukwa cha mafuta owuma. Gloss yochokera m'madzi ilibe fungo lapadera la UV gloss. Chipangizo cha anilox roller chingadziwike poyesa ndi kuyerekeza panthawi yosindikiza. Kukhuthala kwa inki komwe kumawonedwa ndi wogwiritsa ntchito poyesa kumadalira kwambiri nambala ya mzere ndi mtengo wa BCM wa anilox roller.

Anilox roller ikagwiritsidwa ntchito iyenera kusamala ndi mavuto omwe amabwera chifukwa cha izi.

Apa tikunena kuti roller ndi roller ya ceramic yojambulidwa ndi laser, imagwiritsidwa ntchito mu ndege, ndege, kutentha kwambiri, zipangizo zophikira zotsutsana ndi kuvala, malinga ndi kuchuluka kwake, kuya kwake ndi ngodya inayake, mawonekedwe ake, pogwiritsa ntchito laser. Roller iyi imadziwika ndi mtengo wake wokwera, kukana kuvala, ngati igwiritsidwa ntchito bwino, nthawi yake imatha kukhala zaka zingapo; Ngati igwiritsidwa ntchito molakwika, sikuti nthawi yokhayo idzafupikitsidwa, komanso zidutswa za roller.

Mu ndondomeko yogwiritsira ntchito, malo a chopukutira pa makina osindikizira amadalira kusindikiza kwina, kusindikiza kosiyana, malo a chopukutira nawonso ndi osiyana, kotero kusindikiza nthawi zambiri kumayenera kusintha chopukutira cha waya. Pakadali pano, makina opapatiza amagwiritsidwa ntchito makamaka pa chopukutira chachitsulo cholimba, cholemera kwambiri, poyika chopukutira kuti chisalowe pamwamba pa chopukutiracho muzinthu zina zachitsulo. Chifukwa chophimba cha ceramic ndi chopyapyala kwambiri, n'zosavuta kuwononga kosatha pakugunda. Mu ndondomeko yosindikiza ndi kuyeretsa makina, inki iyenera kupewedwa pa chopukutira chouma, kugwiritsa ntchito sopo wapadera woperekedwa ndi opanga inki ochokera m'madzi, pogwiritsa ntchito burashi yachitsulo kutsuka, kuti muwonetsetse kuti ndi yoyera komanso yoyera bwino. Ndipo khalani ndi chizolowezi chogwiritsa ntchito galasi lokulitsa kwambiri kuti muwone dzenje la chopukutira, mukapeza kuti inki imayikidwa pansi pa dzenje la maukonde ndi kuwonjezeka pang'onopang'ono kwa zomwe zikuchitika, iyenera kutsukidwa pakapita nthawi. Ngati njira yomwe ili pamwambapa sigwira ntchito, ultrasound kapena sandblasting ingagwiritsidwe ntchito pochiza, koma iyenera kuchitika motsogozedwa ndi opanga ma roller.

Pogwiritsa ntchito bwino komanso kukonza zinthu, palibe chifukwa chodera nkhawa ndi kuvala kwa roller, mbali zazikulu zogwiritsidwa ntchito poika inki ndi chotsukira, mosiyana, kuvala kwa roller ceramic coating kunganenedwe kuti ndi kochepa. Pambuyo povala pang'ono, wosanjikiza wa inki udzakhala wochepa.

Kodi pali ubale wotani pakati pa kuchuluka kwa mizere yosindikizira ndi kuchuluka kwa mizere ya network ya roller?

Mu nkhani zambiri zomwe zikuyambitsa ukadaulo wosindikiza wa flexographic, chiŵerengero cha mizere ya netiweki yosindikizira ndi chiwerengero cha mizere ya netiweki yozungulira chimayikidwa ngati 1∶3.5 kapena 1∶4. Kutengera ndi zomwe zachitika komanso kusanthula kwa zinthu zomwe zaperekedwa ndi American Flexographic Technology Association (FTA) m'zaka zaposachedwa, wolembayo akukhulupirira kuti mtengo wake uyenera kukhala wapamwamba, pafupifupi 1:4.5 kapena 1:5, ndipo pazinthu zina zosindikizira bwino, chiŵerengerocho chingakhale chokwera kwambiri. Chifukwa chake ndichakuti vuto lovuta kwambiri kuthetsa mukamagwiritsa ntchito gawo losindikiza la flexographic ndi kukula kwa dot. Roller yokhala ndi mizere yambiri ya netiweki imasankhidwa, ndipo gawo la inki ndi locheperako. Kusintha kwa kukula kwa dot kumakhala kosavuta kuwongolera. Mukasindikiza, ngati inki si yokhuthala mokwanira, mutha kusankha inki yochokera m'madzi yokhala ndi utoto wambiri kuti muwonetsetse kuti zinthu zosindikizira zili bwino.
