Nhanganyaya kuRotogravure Printing Process

Chii chinonzi rotogravure kudhinda?

Kudhinda kwegravure ndiko kugadzira nzvimbo yese yeplate yekudhinda yakavharwa neingi, uye wobva washandisa yakasarudzika nzira yekukwenya kubvisa iyo ingi kubva pane isina chinhu chikamu cheinki, kuitira kuti iyo inki inongoiswa mumambure makomba eiyo graphic chikamu cheingi, uye ipapo pasi pechiito chekumanikidza kukuru, iyo inki ichaendeswa kune yakadhindwa pamusoro peiyo nyaya. Gravure printing yakananga kudhinda. Iyo graphic chikamu chepureti yekudhinda ndeye concave, uye dhigirii ye concavity ine nhanho yemufananidzo ine mithunzi yakasiyana, iyo isina chinhu chikamu chedhindiro yekudhinda inosimudzwa, uye mune imwechete cylinder ndege.

Iyo rotogravure maitiro inzira yakananga yekuchinjisa yekudhinda pahuni-pulp fiber based, synthetic, kana laminated substrates, kusanganisira:

-Mafirimu akadai sePET, OPP, naironi, uye PE, PVC, Cellophane

—Mapepa

—Katoni bhodhi

-Aluminium foil

Rotogravure kudhinda maitiro

Rotogravure kudhinda nekuda kweiyo yakakwira dhigirii yeautomation yemuchina wekudhinda, mhando yeplate yakanaka, uye nekudaro maitiro ekushanda ari nyore pane lithographic kudhinda, nyore kugona, kuyerera kwemaitiro kunotevera:

Kugadzirira kusati kwadhinda → pahumburumbira ndiro → gadzirisa kunyoreswa kweruvara → kudhinda zviri pamutemo → kudhindwa kwepashure

Tsanangudzo yemaitiro

Munguva yekudhindwa kwegravure silinda yekudhinda inotenderera mupani yeinki umo maseru akanyorwa anozadza neingi. Sezvo cylinder inotenderera yakajeka pani yeinki, chero inki yakawandisa inobviswa nechiremba blade. Kuwedzera kutenderedza, silinda inounzwa kusangana neiyo substrate, iyo inodzvanywa pairi nerabha yakavharwa impression roller.

Kumanikidzwa kwe roller, pamwe chete ne capillary draw ye substrate, inoguma nekuendeswa kweinki zvakananga kubva mumasero ari muvhareji yekudhinda kusvika pamusoro pe substrate. Sezvo roller inodhinda ichitenderera ichidzokera mupani yeinki, nzvimbo yakadhindwa ye substrate inopinda nemuomesi uye ichienda kune inotevera inodhinda unit, iyo inowanzova nemuvara wakasiyana kana inogona kuva varnish kana coating.

Kunyatsoita ruvara kune kunyoreswa kwemavara kunoitwa kuti kugoneke kuburikidza neatomatiki side uye kureba rerejista control system.

Pamuchina wekudhinda weweb-fed, mushure mekunge ruvara rwega rwega rwadhindwa uye chero mapeji aiswa, dandemutande 'rinodzokororwa' kuita mupumburu wapera.

Iye zvino isu tinotarisisa maitiro ekudhinda anogona kukanganisa zvakananga kunaka kwekudhinda kweimwe yeanonyanya kukosha link - kunyoreswa kwemavara

Mazuvano, ruzhinji rwemichina yekudhinda gravure ichashandisa otomatiki kunyoresa mavara sisitimu yekunyoresa patani, iyo inovandudza zvakanyanya kunyoreswa uye kunaka kwekudhinda.

Paweb gravure printing machine, pane automatic overprinting device yakaiswa. Chigadzirwa chacho chine musoro wekuongorora, pulse generator, magetsi emagetsi, motokari inogadzirisa, overprint kugadzirisa roller nezvimwe zvakadaro.

Kana iyo overprint mucherechedzo pabepa rakadhindwa kuburikidza nemusoro wekutarisa, iyo pulse siginecha ichaendeswa kune yemagetsi controller, kana yechipiri ruvara rweiyo overprint mark isiriyo isati yatanga kana mushure mekutanga ruvara rwechiratidzo, kuitika kwenguva yekupuruzira kuchave kusina kuenzana, saka mutongi wemagetsi anotanga kudzora mota, kuitira kuti ruvara rwekutanga uye rwechipiri ruvara rwekuwedzeredza kwechikanganiso chive nekukanganisa kudiki pakati pemadhindindi.

Pamusoro pezvo, kune zvakare zvinotevera zvinhu zvinogona kukanganisa kunaka uye kugona kwekudhinda, asi isu tichava nemhinduro dzakakodzera.

a) Inki haina kuenzana muruvara

Chiitiko cheperiodic inki ruvara chinoshanduka pane zvakadhindwa. Nzira dzekubvisa dzinosanganisira: kururamisa kutenderera kwe cylinder plate cylinder, kugadzirisa kona uye kudzvinyirirwa kwe squeegee kana kutsiva kusvina kune imwe itsva.

b) Madhindi akapusa uye ane linty

Yakadhindwa mazinga emifananidzo uye nhanho, paste, chiitiko cheburrs pamucheto wemufananidzo. Nzira dzekubvisa dzinosanganisira: kubvisa static magetsi kubva pamusoro pe substrate, kuwedzera polar solvents kune inki, zvakakodzera kuwedzera kudhindwa kwekudhinda, nekugadzirisa nzvimbo ye squeegee nezvimwe zvakadaro.

c) yakavharwa shanduro

Kuomesa inki mumambure ekudhinda, kana buri rekudhinda mesh gomba rinozadzwa nevhudzi rebepa, chiitiko chehupfu hwebepa, chinonzi blocking. Nzira dzekubvisa ndeidzi: kuwedzera zvirimo zvezvinonyungudutsa muinki, kuderedza kukurumidza kwekuomesa inki, kushandiswa kwepamusoro pesimba rekudhinda mapepa.

d) Kuparara kweinki

Chiitiko chemavara anooneka pane chikamu chemunda chekudhinda. Nzira dzekubvisa dzinosanganisira: kuwedzera inki yakaoma kusanganisa mafuta, kuvandudza viscosity yeinki. Gadzirisa kona ye squeegee, wedzera kumhanya kwekudhinda, uye shandura yakadzika-cavity printing plate neshallow-cavity printing plate.

e) Kukwenya

Pane zvimiro zve squeegee pane zvakadhindwa. Nzira dzekubvisa ndeidzi: shandisa inki yakachena isina zvinhu zvekunze zvakasanganiswa mukudhinda. Gadzirisa viscosity, kuoma uye kunamatira kweinki. Shandisa high-quality squeegee, gadzirisa kona pakati pe squeegee uye kudhinda ndiro.

OYANG's dhizaini mainjiniya akaongorora uye akakwenenzvera chimiro chemuchina zvichienderana nekutevedzana kwezvinetso muchirongwa chekudhinda, uye akagadzira Honor Sereis ELS Rotog ravure Printing Machine kubva pamaonero ekugadzirisa marwadzo evashandisi uye indasitiri.

Rotogravure Maitiro mabhenefiti uye mashandisirwo

Maitiro acho anopa kugona kuendesa inki nguva dzose, pamhando dzakasiyana-siyana dze densities, uye nekumhanya kwakanyanya, zvichiita kuti ive yakakodzera kune maapplication anoda emhando yepamusoro yemifananidzo, senge kutsikisa, kurongedza, mavara, kuchengetedza kudhindwa, uye kudhinda kwekushongedza.

Kugara kwenguva refu kwemasilinda ekudhinda anoshandiswa kunoita kuti kudhinda kwegravure kuve kwakakodzera nzira yekupa emhando yepamusoro kudhindwa kwenguva refu kana kudzokorora kumhanya, kuunza mutengo wakanaka pane mamwe maitiro.

OYANG hunyanzvi uye ruzivo

Mugadziri anotyisa, akatarisana nekugadzira kukosha kwevatengi vayo, zvigadzirwa kubva kuOYANG Rotogravure press kugadzira, Mumakore matatu chete OYANG Rotogravure muchina wakavaka mukurumbira wakanaka uye zita rakanaka muChina, uye kune nyika zhinji nematunhu pasirese uko mafekitori evatengi vane yedu Honor series electronic shaft rotogravure printing pressally, uye vanomhanya zvakanyanya.

Mugadziri anokatyamadza zvakaenzana, OYANG yakaisa miitiro mitsva muwebhu-firimu gravure kudhinda munzvimbo dzinoda senge flexible packaging neayo Honor® series rotogravure presses . Kuwana zvakatanhamara zvakadhindwa zvabuda pa-high-end laminated flexible packaging zvinounza matambudziko matsva eiyo gravure printing process, asi kufambira mberi kwetekinoroji, kusununguka kwekushandisa, kukurumidza kutendeuka nguva uye kuderedzwa kutambisa kweOYANG kudhinda kunoita kuti ive imwe yesarudzo dzepamusoro kune vatengi muChina nepasirese.
