Flexographic tshuab luam ntawv muaj qhov zoo ntawm kev hloov pauv dav dav, kev luam ntawv siab, kev tiv thaiv ib puag ncig ntsuab thiab ceev ceev ntau lawm. Nws yog dav siv hauv daim ntawv lo luam ntawv, ntim zaj duab xis, ntawv xim luam ntawv thiab cov khoom siv hluav taws xob nplaum. Nyob rau hauv cov txheej txheem ntawm ntau lawm, cov cuab yeej tsis ua hauj lwm, luam ntawv tsis xws luag, ntau lawm muaj peev xwm poob, feem ntau yog vim tsis txaus tu lub sij hawm. Flexographic luam ntawv yog cov txheej txheem ua kom lub teeb nrawm nrawm, uas yuav tsum muaj cov cuab yeej siv siab huv, qhov tseeb thiab kev ua haujlwm ruaj khov. Kev soj ntsuam txhua hnub thiab kev saib xyuas yog tus yuam sij los txo qhov tsis xws luag, overprinting yuam kev, cov khoom siv jamming tsis ua hauj lwm, txhim kho cov khoom tawm los thiab ua kom lub neej ntev ntawm cov khoom siv. Daim ntawv no piav qhia txog cov ntsiab lus tseem ceeb thiab cov ntsiab lus tswj kev tswj hwm txhua hnub ntawm cov tshuab luam ntawv flexographic.
1, Ink system txij nkawm, kom ntseeg tau tias kev hloov pauv tus cwj mem thiab ruaj khov.
ink path system yog lub hauv paus ntawm tus cwj mem xim, lub hom phiaj ntawm kev saib xyuas txhua hnub nrog rau cov menyuam, tus number case scraper, number case zawj, number case number case twj, thiab lwm yam. mesh cov menyuam ua lub hauv paus ntawm kev hloov ntau tus cwj mem, yooj yim ua rau residual dryness thiab blockage ntawm reticulum. Tom qab lub sijhawm ua haujlwm txhua hnub, yuav tsum ua kom huv si hauv lub sijhawm, tiv thaiv kev sib txuam ntawm tus number case thiab cov kua nplaum ntawm daim tawv nqaij residue, zam cov txheej txheem tsim cov xim tsis sib xws, cov ntawv luam tawm, xim sib txawv thiab lwm yam. Nyob rau tib lub sijhawm, txhawm rau txheeb xyuas qhov flatness thiab hnav ntawm scraper hniav txhua hnub, kom ntseeg tau tias lub siab tsis sib xws, nruj kev sib koom tes, tiv thaiv tus number case to, txaws tsis ua haujlwm. Tsis tas li ntawd, kev tu tsis tu ncua ntawm impurities nyob rau hauv tus number case tank, xyuas qhov smoothness ntawm tus number case twj tso kua mis thiab raj, xyuas kom ib tug tsis tu ncua ndlwg ntawm number case, uninterrupted mov ntawm tus number case, los ntawm qhov chaw kom tsis txhob muaj teeb meem ntawm printing xim txawv.
2. Txheeb xyuas cov txheej txheem dov kom tsis txhob muaj kev luam ntawv tsis raug.
Lub tshuab dov ncaj qha txiav txim siab qhov tseeb ntawm kev luam ntawv siab thiab cov duab kos duab, thiab yog qhov tseem ceeb ntawm kev saib xyuas txhua hnub. Cov neeg ua haujlwm yuav tsum tau kuaj xyuas qhov xwm txheej ntawm cov menyuam thiab cov menyuam roj hmab txhua hnub, ntxuav cov nplaum, plua plav thiab number case stains ntawm qhov chaw ntawm cov menyuam raws sijhawm, thiab tshawb xyuas qhov puas, tsis zoo, kev laus thiab deformation ntawm cov menyuam. Nyob rau tib lub sijhawm, qhov sib luag thiab kev ua haujlwm siab ntawm txhua tus menyuam ncej yog ntsuas kom ntseeg tau tias qhov sib npaug ntawm qhov siab ntawm ob sab, txhawm rau tiv thaiv cov npoo ntawm qhov muag tsis pom vim qhov siab dhau, thiab qhov tsis xws luag tshwm sim los ntawm lub siab tsis txaus. Rau cov menyuam phaj, kom tsis tu ncua xyuas cov concentric thiab adhesion ntawm lub phaj luam ntawv kom paub meej tias lub phaj yog du, npuas -dawb, xoob npoo, kom tsis txhob luam ntawv tsis zoo vim tsis zoo adhesion ntawm cov khoom phaj.
3, Cov khoom siv tuav thiab tswj kev tswj xyuas kom tsis txhob overprinting sib txawv
Nyob rau hauv cov txheej txheem ntawm kev kub ceev luam ntawv, kev ruaj ntseg ntawm cov khoom noj ncaj qha cuam tshuam qhov tseeb ntawm overprint. Kev saib xyuas txhua hnub yuav tsum tsom mus rau kev tshuaj xyuas qhov system nruj thiab kho qhov system, debugging nro tsis, kom ntseeg tau tias kev sib khi tsis sib xws thiab kev ua haujlwm zoo ntawm cov khoom siv thauj khoom, tshem tawm cov teeb meem ntawm cov khoom ncab, pob zeb thiab sib txawv. Nyob rau tib lub sij hawm ntxuav qhov chaw ntawm cov ntawv qhia cov menyuam kom tiv thaiv kev txav los ntawm zawv zawg. Tsis tas li ntawd, txhua hnub so kom pom qhov muag thiab nrhiav cov sensors yuav tsum tau tshem tawm cov plua plav thiab tus number case stains los ntawm qhov chaw, xyuas kom meej qhov kev xav tau thiab qhov chaw raug, tsis txhob luam ntawv tsis raug thiab batch defects vim sensor tsis ua hauj lwm, thiab xyuas kom ruaj khov nyob rau hauv siab - ceev ntau lawm.
4. Kev ziab thiab ib puag ncig txhawb kev tswj xyuas.
drying system tu, yooj yim ua rau number case kom qhuav, rov qab adhesion, ink blurring thiab lwm yam teeb meem zoo. Ua ntej thiab tom qab kev tsim khoom txhua hnub, cov kav dej qhuav thiab cov cua kub lim yuav tsum tau ntxuav tsis tu ncua kom tshem tawm cov pa cua thiab ua kom cov cua kub zoo sib xws thiab qhov kub thiab txias. Raws li kev ceev ntawm kev tsim khoom, cov khoom siv thiab tus cwj pwm tus cwj pwm, tsim nyog phim qhov ziab kub thiab cua ceev, tiv thaiv kev luam ntawv tsis zoo vim tsis txaus dryness. Nyob rau tib lub sijhawm tswj qhov kub thiab av noo ntawm lub rooj cob qhia, kom tsis txhob muaj qhov txawv txav ntawm qhov kub thiab av noo ua rau cov khoom deformation thiab ink Performance fluctuations, kom ua tau raws li qhov yuav tsum tau ua ntawm flexographic precision luam ntawv.
5. Kev tshuaj xyuas cov khoom sib kis thiab cov chaw muaj kev nyab xeeb.
Cov qauv sib kis ntawm cov khoom siv yog lub hauv paus ntawm kev ua haujlwm ruaj khov ntawm tag nrho lub tshuab. Peb yuav tsum xyuas cov lubrication ntawm cov khoom sib kis xws li cov saw hlau, cov kabmob thiab cov iav txhua hnub, ntxiv cov roj lubricating tshwj xeeb hauv lub sijhawm kom tsis txhob ziab, suab nrov txawv txav, txhaws thiab ua rau hnav. Loosen screws thiab pob qij txha rau cov khoom siv fastening thiab xyuas kom muaj kev vibration thiab suab nrov txawv txav thaum ua haujlwm. Nyob rau tib lub sijhawm, kev tshuaj xyuas qhov chaw nyab xeeb yog ua los xyuas qhov kev ncaj ncees ntawm cov khoom siv tiv thaiv thiab qhov rhiab heev ntawm cov chaw nres tsheb thaum muaj xwm ceev, tiv thaiv kev ua haujlwm tsis zoo thiab kev ua haujlwm tsis raug cai ntawm cov cuab yeej tiv thaiv kev nyab xeeb, thiab tsim kom muaj kev ruaj ntseg ntau lawm kab.
6. INTRODUCTION Abstracts
Lub hauv paus ntawm kev saib xyuas txhua hnub ntawm cov tshuab luam ntawv flexographic yog kev kho kom zoo, kev tsim qauv thiab kev tsim qauv. Kev tshuaj xyuas thiab kev saib xyuas ntawm tus cwj mem txoj kev, dov, pub mis, ziab thiab kis kab mob tuaj yeem daws cov teeb meem sib txawv ntawm qhov muag plooj, xim sib txawv, luam ntawv tsis raug thiab adhesion hauv kev luam ntawv, zoo heev txhim kho cov khoom tsim, txo cov khoom tsis ua hauj lwm thiab downtime, txo cov nqi tu thiab ua kom lub neej ntev ntawm cov khoom siv thiab cov khoom siv. Cov tuam txhab lag luam yuav tsum ua raws li cov txheej txheem tswj xyuas cov cuab yeej, ua ntej- kev tshuaj xyuas ua haujlwm, hauv - kev tshuaj xyuas ua haujlwm thiab tom qab- hloov kho thiab tu, xyuas kom cov khoom ruaj khov, thiab txhim kho kev luam ntawv thiab kev ua haujlwm zoo.
