Intshayelelo yeNkqubo yoShicilelo yeRotogravure

Yintoni ushicilelo lwe-rotogravure?

yoshicilelo Gravure kukwenza yonke umphezulu ipleyiti yoshicilelo ziqatywe inki, kwaye ke usebenzise indlela yokukrazula ekhethekileyo ukususa i-inki kwindawo engenanto ye-inki, ukuze inki ifakwe kuphela kwimingxuma yomnatha yenxalenye yomzobo we-inki, kwaye ke phantsi kwesenzo soxinzelelo olukhulu, i-inki iya kudluliselwa kwi-substrate kumphezulu wokushicilela. Ushicilelo lweGravure lushicilelo oluthe ngqo. Inxalenye yegraphic yepleyiti yokushicilela i-concave, kwaye iqondo le-concavity kunye nenqanaba lomfanekiso linama-shades ahlukeneyo, inxalenye engenanto yepleyiti yokushicilela iphakanyisiwe, kwaye kwi-cylinder plane efanayo.

Inkqubo ye-rotogravure yindlela yokudlulisa ngokuthe ngqo yokushicilela kwi-wood-pulp fiber esekelwe, eyenziwe, okanye i-laminated substrates, kuquka:

-Iifilimu ezinjengePET, OPP, inayiloni, kunye nePE,PVC, Cellophane

—Amaphepha

—Ibhodi yebhokisi

-Ifoyile yealuminiyam

Inkqubo yoshicilelo lweRotogravure

I-Rotogravure yoshicilelo ngenxa yezinga eliphezulu lokuzenzekelayo kumatshini wokushicilela, umgangatho wepleyiti ulungile, kwaye ngoko ke inkqubo yokusebenza ilula kunokushicilela i-lithographic, kulula ukuyilawula, ukuhamba kwenkqubo ngolu hlobo lulandelayo:

Ukulungiselela ushicilelo lwangaphambili → kwipleyiti yesilinda → lungelelanisa ubhaliso lombala → ushicilelo olusesikweni → ukusetyenzwa kweposi

Inkcazo yenkqubo

Ngethuba lenkqubo yokushicilela i-gravure i-cylinder yokushicilela ijikeleza kwi-pan ye-inki apho iiseli ezikroliweyo zigcwalisa i-inki. Njengoko i-cylinder ijikeleza ngokucacileyo kwi-pan ye-inki, nayiphi na inki engaphezulu isuswe ngugqirha. Ukuqhubela phambili, i-cylinder idibaniswa ne-substrate, ecinezelwe kuyo yi-rubber egubungele i-impression roller.

Uxinzelelo lwe-roller, kunye ne-capillary draw ye-substrate, kubangela ukuhanjiswa ngokuthe ngqo kwe-inki kwiiseli kwi-cylinder yokushicilela ukuya kumphezulu we-substrate. Njengoko i-roller yokushicilela ijikeleza emva kwi-pan ye-inki, indawo eprintiweyo ye-substrate iqhubela phambili nge-dryer kunye neyunithi yokushicilela elandelayo, ngokuqhelekileyo umbala ohlukileyo okanye inokuba yi-varnish okanye i-coating.

Umbala ochanekileyo wokubhaliswa kombala wenziwa ukuba kwenzeke ngecala elizenzekelayo kunye neenkqubo zokulawula irejista yobude.

Kumatshini wokushicilela we-web-fed, emva kokuba umbala ngamnye uprintwe kwaye naziphi na iicoatings ziqatyiwe, iwebhu 'iphinda ijikwe' ibe ngumqulu ogqityiweyo.

Ngoku sigxininisa kwinkqubo yoshicilelo inokuchaphazela ngokuthe ngqo umgangatho woshicilelo lwezinye zekhonkco ezibalulekileyo - ukubhaliswa kombala

Kule mihla, uninzi loomatshini boshicilelo begravure baya kusebenzisa inkqubo yokubhaliswa kombala ngokuzenzekelayo kubhaliso lwepateni, ethi iphucule kakhulu impumelelo yobhaliso kunye nomgangatho woshicilelo.

Kumatshini wokushicilela we-web gravure, kukho isixhobo sokushicilela esizenzekelayo esifakiweyo. Isixhobo sinentloko yokuskena, i-pulse generator, isilawuli se-elektroniki, i-motor adjusting, i-overprint adjusting roller kunye nokunye.

Xa uphawu olungaphezulu kwiphepha eliprintiweyo ngentloko yokuskena, umqondiso wepulse uya kudluliselwa kwisilawuli se-elektroniki, ukuba umbala wesibini wophawu olugqithisiweyo ungalunganga ngaphambi okanye emva kombala wokuqala wophawu, ukwenzeka kwexesha le-pulse liya kuba lingalingani, ngoko umlawuli we-elektroniki uqalise ukulawula i-motor, ukuze umbala wokuqala kunye nombala wesibini we-overprint ye-overprints ibe nephutha elincinci lokulawula phakathi kwe-overprints encinci.

Ukongeza, kukho ezi zinto zilandelayo ezinokuchaphazela umgangatho kunye nokusebenza kakuhle koshicilelo, kodwa siya kuba nezisombululo ezifanelekileyo.

a) I -inki ayilingani ngombala

Iphenomenon yokutshintsha kombala we-inki kwizinto eziprintiweyo. Iindlela zokuphelisa ziquka: ukulungisa ukujikeleza kwe-cylinder yeplate yokushicilela, ukulungelelanisa i-angle kunye noxinzelelo lwe-squeegee okanye ukutshintshwa kwe-squeegee entsha.

b) Iiprinta ezintsonkothileyo kunye nezilinty

Amanqanaba emifanekiso eprintiweyo kunye nenqanaba, unamathisele, isenzeko se-burrs kumda womfanekiso. Izindlela zokuphelisa zibandakanya: ukususa umbane osisigxina ukusuka kumphezulu we-substrate, ukongeza i-solvents ye-polar kwi-inki, ngokufanelekileyo ukwandisa uxinzelelo lokushicilela, kunye nokulungelelanisa indawo ye-squeegee kunye nokunye.

c) inguqulelo evaliweyo

Ukomisa i-inki kumnatha wepleyiti yoshicilelo, okanye umngxuma wepleyiti yokushicilela ugcwaliswa ziinwele zephepha, isenzeko somgubo wephepha, obizwa ngokuba yibhlokhi. Iindlela zokuphelisa zezi: ukwandisa umxholo we-solvents kwi-inki, ukunciphisa isantya sokumisa i-inki, ukusetyenziswa kwephepha eliphezulu lokushicilela iphepha.

d) Ukuchitheka kwe-inki

Isenzeko samabala avelayo kwinxalenye yentsimi yoshicilelo. Iindlela zokuphelisa ziquka: ukongeza ioli yokudibanisa inki enzima, ukuphucula i-viscosity ye-inki. Lungisa i-engile ye-squeegee, ukwandisa isantya sokushicilela, kwaye ubeke endaweni yepleyiti yokushicilela enzulu kunye ne-shallow-cavity printing plate.

e) Krwela

Kukho imikhondo ye-squeegee kushicilelo. Iindlela zokuphelisa zezi: sebenzisa i-inki ecocekileyo ngaphandle kwezinto zangaphandle ezixutywe kushicilelo. Lungisa i-viscosity, ukoma kunye nokubambelela kwi-inki. Sebenzisa i-squeegee ekumgangatho ophezulu, lungisa i-engile phakathi kwe-squeegee kunye nepleyiti yokushicilela.

Iinjineli zoyilo ze-OYANG zahlalutya kwaye zaphucula isakhiwo somatshini ngokuhambelana noluhlu lweengxaki kwinkqubo yokushicilela, kwaye yenze i-Honor Sereis ELS Rotog ravure Machine yokushicilela ukusuka kumbono wokusombulula iintlungu zabasebenzisi kunye noshishino.

Iinzuzo zeRotogravure kunye nezicelo

Inkqubo inikezela ngesakhono sokudlulisa i-inki ngokungaguqukiyo, kuluhlu olubanzi loxinaniso, kunye nesantya esiphezulu, iyenza ilungele izicelo ezifuna umgangatho ophezulu womfanekiso, njengokupapasha, ukupakishwa, iilebhile, ukuprintwa kokhuseleko, kunye noshicilelo lokuhombisa.

Ubume bexesha elide leesilinda zoshicilelo ezisetyenzisiweyo kwenza ushicilelo lwegravure lube yinkqubo efanelekileyo yokubonelela ngoshicilelo olukumgangatho ophezulu kwimitsi ede kakhulu okanye ephindaphindwayo rhoqo, ukuhambisa inzuzo yeendleko ngaphezu kwezinye iinkqubo.

Ubuchule be-OYANG nolwazi

Umqalisi owoyikekayo, ogxile ekudaleni ixabiso kubathengi bakhe, iimveliso ezivela kwi-OYANG Rotogravure press making, Kwiminyaka nje emithathu i-OYANG Rotogravure press iye yazakhela igama elihle kunye negama elihle e-China, kwaye kukho amazwe amaninzi kunye nemimandla ejikeleze ihlabathi apho iifektri zabathengi zine-Honour series electronic shaft rotogravure printing printably, kwaye ziqhuba ngokuzinzileyo.

I-innovator enomdla ngokulinganayo, i-OYANG ibeke imigangatho emitsha kwi-web-film gravure printing kwiindawo ezifunayo ezifana nokupakishwa okuguquguqukayo kunye ne- Honor® series rotogravure presses . Ukufezekisa iziphumo ezigqwesileyo zokushicilela kwi-high-end laminated flexible packaging kubangela imingeni emitsha yenkqubo yokushicilela i-gravure, kodwa ukuqhubela phambili kwezobuchwepheshe, ukusetyenziswa lula, ixesha lokuguqula ngokukhawuleza kunye nokunciphisa inkunkuma yokushicilela i-OYANG kubenza ukuba bakhethe ukhetho oluphezulu kubathengi e-China nakwihlabathi jikelele.
