Ukadaulo Watsopano Usanu ndi Uwiri wa Makina Osindikizira a Gravure

1. Ukadaulo Wodzipangira ndi Kudzipangira Wokha wa Makina Osindikizira a Gravure 

Mu njira yopangira, ukadaulo wodziyimira wokha wokwera ndi kutsika umakweza zokha mipukutu ya mainchesi ndi m'lifupi osiyanasiyana kupita ku siteshoni yolumikizira kudzera mu muyeso wolondola ndi kuzindikira, kenako chipangizo chonyamulira chimasuntha yokha mipukutu yomalizidwa kuchokera ku siteshoni ya zida. Zimazindikira kulemera kwa zinthu zopangira ndi zinthu zomalizidwa panthawi yonyamula, yomwe imalumikizidwa ndi ntchito yoyang'anira kupanga, m'malo mwa njira yogwiritsira ntchito pamanja, yomwe sikuti imangothetsa vuto lomwe makina osindikizira gravure amafunikira kuti agwire bwino ntchito koma sangathe kukwaniritsa ntchito zothandizira, komanso imawongolera kwambiri magwiridwe antchito opanga. , kuchepetsa mphamvu ya ogwira ntchito.

2. Ukadaulo wodulira makina osindikizira gravure wokha 

Pambuyo poti ukadaulo wodulira wokha wagwiritsidwa ntchito, njira yonse yodulira yokha imangofunika kuyika mpukutu wazinthuzo pa chosungira chakudya, ndipo njira yonse yodulira ikhoza kumalizidwa popanda kutenga nawo mbali pamanja mu njira yotsatira yodulira. Potengera filimu ya BOPP yokhala ndi makulidwe a 0.018mm mwachitsanzo, kudula kokhazikika kumatha kuwongolera kutalika kwa zinthu zotsala za mpukutu mkati mwa 10m. Kugwiritsa ntchito ukadaulo wodulira wokha pazida zosindikizira za gravure kumachepetsa kudalira kwa zidazo pa ogwiritsa ntchito ndikuwonjezera magwiridwe antchito.

3. Ukadaulo wanzeru wolembetsa pasadakhale makina osindikizira gravure 

Kugwiritsa ntchito ukadaulo wanzeru wolembetsa pasadakhale makamaka kumachepetsa njira zomwe ogwiritsa ntchito amagwiritsa ntchito rula kuti alembetse pamanja mbaleyo mu njira yoyambirira yolembetsa mbale, ndikugwiritsa ntchito mwachindunji kulumikizana kwa munthu ndi munthu pakati pa ma key grooves pa plate roller ndi mizere ya chizindikiro pamwamba pa plate. Kutsimikizira kokha kwa bit kumazindikira njira yoyambira yofananira. Njira yoyamba yofananira mbale ikatha, dongosololi limazungulira lokha gawo la plate roller kupita pamalo pomwe kulembetsa pasadakhale kokha kungachitike malinga ndi kuwerengera kutalika kwa zinthu pakati pa mitundu, ndipo ntchito yolembetsa pasadakhale imachitika yokha.

4. Tanki ya inki yosindikizira ya gravure yokhala ndi chopukutira chotsika 

Zinthu zazikulu za makina osindikizira gravure: Amatha kuletsa bwino kutayidwa kwa inki pogwiritsa ntchito liwiro lalikulu. Thanki ya inki yotsekedwa pang'ono imatha kuchepetsa kusinthasintha kwa zinthu zachilengedwe ndikuwonetsetsa kuti inkiyo imakhala yokhazikika panthawi yosindikiza mwachangu. Kuchuluka kwa inki yozungulira yomwe imagwiritsidwa ntchito kwachepetsedwa kuchoka pa 18L kufika pa 9.8L tsopano. Popeza nthawi zonse pamakhala kusiyana kwa 1-1.5mm pakati pa chosinthira cha inki chotsika ndi chosinthira cha mbale, pochita chosinthira cha inki chotsika ndi chosinthira cha mbale, imatha kulimbikitsa kusamutsa inki kupita ku maselo a chosinthira cha mbale, kuti ikwaniritse bwino kubwezeretsedwa kwa toni ya Shallow net.

5. Dongosolo Lanzeru Loyang'anira Deta la Makina Osindikizira a Gravure

Ntchito zazikulu za makina osindikizira a gravure: nsanja yanzeru ya data yomwe ili pamalopo imatha kuwerenga magawo ogwirira ntchito ndi momwe makina osankhidwa amagwirira ntchito, ndikuzindikira kusungira kofunikira koyang'anira ndi kusunga magawo; nsanja yanzeru ya data yomwe ili pamalopo imatha kulandira magawo a ndondomeko ndi magawo operekedwa ndi nsanja yanzeru yakutali. Zofunikira zokhudzana ndi dongosolo, ndikukhazikitsa chilolezo chosankha ngati mukufuna kutsitsa magawo a ndondomeko omwe aperekedwa ndi nsanja yanzeru yakutali ku HMI yamakina olamulira, ndi zina zotero.

6. Kupsinjika kwa Digito kwa Gravure Press 

Kupsinjika kwa digito ndikusintha kuthamanga kwa mpweya komwe kumayikidwa ndi valavu yamanja kufika pamtengo wofunikira womwe umayikidwa mwachindunji ndi mawonekedwe a munthu ndi makina. Kupsinjika kwa gawo lililonse la zida kumafotokozedwa molondola komanso mwa digito mu mawonekedwe a munthu ndi makina, zomwe sizimangochepetsa zidazo popanga. Kudalira kwa wogwiritsa ntchito, komanso kugwiritsa ntchito mwanzeru kwa zidazo kumawonjezeka.

7. Ukadaulo wosunga mphamvu pa mpweya wotentha wa makina osindikizira gravure 

Pakadali pano, ukadaulo wosunga mphamvu mu mpweya wotentha womwe umagwiritsidwa ntchito pamakina osindikizira gravure makamaka umaphatikizapo ukadaulo wotenthetsera pampu yotenthetsera, ukadaulo wa mapaipi otenthetsera komanso makina oyendetsera mpweya wotentha okha ndi LEL control.

1, Ukadaulo wotenthetsera pampu yotenthetsera. Mphamvu ya mapampu otenthetsera ndi yokwera kwambiri kuposa yamagetsi. Pakadali pano, mapampu otenthetsera omwe amagwiritsidwa ntchito mumakina osindikizira gravure nthawi zambiri amakhala mapampu otenthetsera a mphamvu ya mpweya, ndipo mayeso enieni amatha kusunga mphamvu ndi 60% mpaka 70%.

2, Ukadaulo wa chitoliro chotenthetsera. Pamene makina otentha a mpweya pogwiritsa ntchito ukadaulo wa chitoliro chotenthetsera akuyenda, mpweya wotentha umalowa mu uvuni ndipo umatuluka kudzera mu chotulutsira mpweya. Chotulutsira mpweya chimakhala ndi chipangizo china chobwezera mpweya. Gawo lina la mpweya limagwiritsidwa ntchito mwachindunji mu kayendedwe ka mphamvu ya kutentha kwachiwiri, ndipo gawo lina la mpweya limagwiritsidwa ntchito ngati makina otetezeka otulutsira mpweya. Monga gawo ili la mpweya wotentha kuti mpweya wotulutsira mpweya ukhale wotetezeka, chosinthira kutentha cha chitoliro chotenthetsera chimagwiritsidwa ntchito kubwezeretsanso kutentha kotsala bwino.

3, Dongosolo loyendetsa mpweya wotentha lokha lokha lokhala ndi LEL control. Kugwiritsa ntchito dongosolo loyendetsa mpweya wotentha lokha lokha lokhala ndi LEL control kungathandize kukwaniritsa zotsatirazi: poganiza kuti malire ocheperako a LEL akwaniritsidwa ndipo chosungunulira chotsala sichidutsa muyezo, mpweya wobwerera wachiwiri ungagwiritsidwe ntchito kwambiri, zomwe zingasunge mphamvu ndi pafupifupi 45% ndikuchepetsa mpweya wotulutsa utsi. Mzere 30% mpaka 50%. Kuchuluka kwa mpweya wotulutsa utsi kumachepetsedwa mofananamo, ndipo ndalama zomwe zimagwiritsidwa ntchito pokonza mpweya wotulutsa utsi zitha kuchepetsedwa kwambiri ndi 30% mpaka 40% kuti ziletse kutulutsa mpweya mtsogolo.
