Izilumkiso zokwenziwa kweekomityi zephepha (2)

Imiqathango yokwenzaiikomityi zephepha
6. Imbuyekezo yokuphuma
Ngenxa ye-elasticity ye-flexographic plate material, i-1% yamachaphaza ayikwazi ukuma kakuhle kwaye ilahleka ngokulula ngexesha lokushicilela. I-2% yamachaphaza ngamachaphaza amancinane anokuma xa iprintwa, yaye i-2% yamachaphaza idla ngokunyuka ukuya kutsho kwi-10%, amachaphaza amancinane kwisampulu eprintiweyo yi-10%, yaye amachaphaza angaphantsi kwe-10% akanakuprintwa.
Ngeli xesha, ezi ndlela zilandelayo zingasetyenziselwa ukuphepha ngobuchule kunye nokusombulula.
â‘‘Ungawahoyi amanye amanqanaba ngaphandle kokuchaphazela isiphumo soshicilelo, oko kukuthi, tshintsha amachaphaza angaphantsi kwe-2% ukuya kwi-2%.
⑵ Guqula onke amanqaku abalulekileyo angaphantsi kwe-2% ukuya kwi-2% yamachaphaza. Ngenxa yokuba imbono yomntu ngombala inxulumene, kwezinye iimeko iya kuvelisa inkohliso yokuba i-2% yamachaphaza ithathwa njengeengongoma eziphambili.
⑶ Buyisela umbala othile ngeminye imibala. Ngokomzekelo, umnyama udla ngokusetyenziselwa ukutshintshela eluhlaza okwesibhakabhaka ekupakishweni kokutya, umnyama usetyenziselwa ukubuyisela obomvu kumagqabi, okanye umbala okhanyayo we-hue efanayo usetyenziselwa ukubuyisela ubumnyama, njl. Iindlela zihlukile.
7. Nika ingqalelo ekunciphiseni nasekukhanyeni kwebhakhowudi kunye nobukhulu bomgca wombhalo
Imigca eprintiweyo ngoshicilelo lwe-flexographic iya kuba ngqindilili, ibangela ukuba ibhakhowudi iqatywe. Ngoko ke, ibarcode kufuneka incitshiswe, kwaye amacala asekhohlo nasekunene kufuneka ashiywe engenanto. Qaphela ukuba imigca emincinci yokubhaliweyo kufuneka ilawulwe ngaphezulu kwe-0.04mm.
8. Lungiselela
Onke amagama kunye neepatheni kwindebe yephepha kufuneka zicwangciswe ngononophelo ngokwe-arc yesangqa esizotyiweyo (isangqa sokubumba imela), ukuze amagama kunye neepateni zibe kumgca othe tye emva kokuba imveliso isongelwe kwimilo yekomityi. . Kwisalathiso esithe nkqo, ulungelelwaniso kufuneka lusekelwe kumgca othe ngqo otsalwe kwi-angle ethile ukusuka kumbindi wesangqa. Lo mgca kufuneka wenziwe ezimbalwa ngakumbi kwimveliso ukuququzelela ukulungelelaniswa kunye nokulinganisa abalinganiswa okanye iipatheni kwiindawo ezahlukeneyo. Ngaphambi kokucwangcisa, kufuneka ubeke ingqalelo ekuguquleni konke okubhaliweyo kwifom yolwandlalo, ukwenzela ukuba kube lula ukuhanjiswa komgca othile okanye abalinganiswa abambalwa, kwaye kwangaxeshanye uphephe ukutshintshwa kwekhompyuter ngenxa yokungabikho kwefonti kunye nesiqhelo. Umsebenzi awunakuqhuba, ngoko ke i Phambi kolungiselelo lokubhaliweyo, kufuneka ukhangele ukuba kukho nayiphi na impazamo kwigalelo lombhalo, kuba kuya kuba nzima kakhulu ukulungisa okubhaliweyo emva kokuba ijikajika litshintshiwe.
9. Ukubekwa
Nika ingqalelo kwezi ziqulatho zilandelayo xa usenzaiikomityi zephepha.
''Imveliso yokwaleka
Umsebenzi we-bead kukukhusela inxalenye yegraphic (okt okuqinileyo, umgca, kunye nenxalenye yomfanekiso oqhubekayo) kwipleyiti, kunye nokuthintela ipleyiti yokushicilela ekuhambeni ngexesha lokushicilela kunye nenkqubo yokushicilela ayinakugqitywa kakuhle. Ngokwaleko, imigca emibini ethe nkqo iya kubonakala kumacala omabini epleyiti, eya kusebenza njengenkxaso yoshicilelo lwe-flexo yaseTshayina ngexesha loshicilelo. Ngoko ke, ibar yoxinzelelo kufuneka ibonakale kwipleyiti yombala ngamnye kwaye ibe nombala ogcweleyo, kwaye ibha yoxinzelelo nganye kufuneka ibe "nomgca wesiphambano".
⑵ Indlela yokumisela
Kukho iindidi ezimbini zokufakwa kwekomityi yephepha: Uhlobo lwe-S kunye nohlobo lwe-T. Iindlela ezahlukeneyo zokubeka zinokukhethwa ngokwesayizi yephepha lokushicilela lomthengi.
(3) Uphawu olucacileyo lwenguqu encitshisiweyo yepleyiti ye-flexographic kukuba i-elastic. Xa ipleyiti ye-flexographic ifakwe kwi-cylindrical cylinder, ipleyiti yokushicilela ivelisa i-deformation egobayo kunye nomphezulu we-cylinder. Le deformation ichaphazela iipateni kunye nabalinganiswa kumphezulu ipleyiti yoshicilelo, kwaye nokuba nzulu The deformation. Olu hlobo lwe-static deformation kwi-axial direction of the cylinder emva kokuba i-flexographic plate ifakwe kwi-cylinder ihlala ingenakunqandwa. Ukuze uhlawule ukuchithwa komfanekiso oprintiweyo, kuyimfuneko ukunciphisa ubungakanani bomzobo ohambelanayo kwifilimu engalunganga. Xa uyila imibhalo-ngqangi okanye ukwahlula kombala phambi kokwenziwa kwepleyiti, ukwandiswa kwepleyiti yoshicilelo kufuneka kuqwalaselwe, kwaye ixabiso elihambelanayo kufuneka lithatyathwe kubude be-axial bombhalo-ngqangi ukubuyisela, ukuze imveliso eprintiweyo iya kuhlangabezana neemfuno zobungakanani. Kungenxa yoko le nto iifayile kufuneka zikhubazeke ngexesha lokufakwa emva kokufakwa.
Iiparamitha ezinxulumene nomlinganiselo wokunciphisa ziyi-radius ye-cylinder, ubukhulu be-tape ephindwe kabini, kunye nobukhulu beplate.
Izinga lokunciphisa (ipesenti)=K/R×apho i-R iyisangqa sombhobho kunye ne-K yi-coefficient, exhomekeke kubukhulu bezinto zepleyiti ezisetyenzisiweyo.
