Qhov no yog ib qho ntawm cov lus nug ntau tshaj plaws uas kuv hnov los ntawm cov neeg yuav khoom ntsuas cov khoom siv rau lawv cov hnab ntawv cov kab ntau lawm: puas ntxiv cov luam ntawv ua haujlwm hloov pauv lub tshuab ua haujlwm li cas? Los yog nws tsuas yog tib lub hnab ntawv tshuab nrog ib qho ntxiv module bolted rau?
Cov lus teb tiag yog cov ncauj lus kom ntxaws tshaj qhov yooj yim yog los yog tsis. Lub ntsiab molding txheej txheem rau antawv hnab tshuab nrog luam ntawv yog tib yam li rau cov tshuab txheem. Daim ntawv tseem yuav tsum tau txiav, folded, glued, thiab molded los ntawm tib theem pib ntawm cov kauj ruam. Tab sis hauv kev luam ntawv, muaj cov txheej txheem tshiab, tsim cov khoom los xav txog thiab kev hloov pauv ntawm kev ua haujlwm. Tag nrho cov no cuam tshuam rau tag nrho cov txheej txheem ntau lawm. Nws yog ib qho tseem ceeb rau txhua tus neeg npaj yuav cov khoom siv zoo li no kom paub cov kauj ruam zoo ib yam thiab sib txawv.
Lub Hom Phiaj: Yuav Ua Li Cas Daim Ntawv Hnab Ua Haujlwm
Ob lub tshuab ntawv lub hnab ntim khoom thiab cov ntawv luam tawm qhia tib lub ntsiab lus tseem ceeb rau kev tsim lub hnab. Qhov no tsim nyog tsim kom meej meej ua ntej nkag mus rau hauv qhov sib txawv. Antawv hnab tshuab nrog luam ntawvtseem cia siab rau tib txoj kev ua ntu zus; lub tshuab luam ntawv muaj nuj nqi ntxiv qhov nyuaj yam tsis hloov lub hnab tseem ceeb - ua tshuab.
Ib lub hnab ntawv, txawm hais tias nws nqa luam ntawv, pib ua ib daim ntawv tiaj tus - feem ntau kraft ntawv hauv qhov hnyav li ntawm 50 g / m² txog 120 g / m² nyob ntawm lub hnab lub zog thiab qhov loj me. Daim ntawv yog unwound los ntawm ib yob, ua tiav los ntawm ib tug series ntawm txoj kev chaw nres tsheb, thiab emerges raws li ib tug tiav lub hnab.
Cov txheej txheem tseem ceeb ntawm cov tshuab lag luam feem ntau ua raws li qhov kev txiav txim no:
Sheet feeding thiab txiav:Daim ntawv yob pub ib daim ntawv txuas mus ntxiv, uas yog txiav mus rau qhov ntev preset los ntawm lub tshuab txiav los yog cov txheej txheem txheej txheem. Qhov txiav ntev txiav txim siab lub hnab qhov siab.
Sab folding thiab tubing txoj kev:Daim ntawv txiav mus los ntawm kev sib sau cov phaj thiab cov yob. Cov folds sab ntug sab hauv. Qhov no ua rau lub raj zoo uas muab lub hnab rau nws lub cev. Cov kauj ruam no yuav suav nrog ua ntej -folding rau lub hnab gusseted.
Hauv qab gluing thiab sealing:Lub raj qhib kawg yog folded rau hauv lub tiaj tiaj hauv qab, thiab cov nplaum yog siv rau lub ntsej muag. Siab rollers nias lub nplaum nplaum kaw. Qhov no yog cov kauj ruam uas xav tau tshaj plaws, vim nws yuav tsum tuav hauv qab thaum lub hnab ntim puv.
Hauv qab folding thiab qhib:Tom qab cov kua nplaum ua tiav, lub raj ua tiav raug txiav rau hauv ib lub hnab ntim khoom thiab qhib, feem ntau yog los ntawm lub dav hlau cua lossis tshuab qhib, los npaj nws rau kev sau.
Handle forming (rau cov hnab tuav):Yog hais tias lub hnab tsim muaj xws li twisted ntawv tuav, ib tug tuav txuas chaw nres tsheb txiav loops los ntawm ib tug thib ob daim ntawv yob, twists, thiab khi lawv mus rau lub hnab lub cev.
Cov kab ke no - pub, txiav, quav, kua nplaum, qhib - yog cov khoom siv DNA sib koom ntawm txhua lub hnab ntim khoom lag luam. Tsis muaj lub tshuab luam ntawv hloov pauv cov haujlwm tseem ceeb no. Txawm nyob rau ibntawv hnab tshuab nrog luam ntawv, cov kauj ruam tsim no tseem mechanically tsis hloov.
Qhov twg luam ntawv ntxiv complexity
Cov khoom lag luam luam tawm hauv lub tshuab luam ntawv lub hnab ntim khoom feem ntau yog sib xyaw ua ke hauv nruab nrab qhov chaw nres tsheb lossis ua ntej - txheej txheem ua ntej uas tshwm sim ua ntej lub hnab loj - txoj kab. Qhov kev sib koom ua ke no yog qhov uas cov ntsiab cai ua haujlwm pib sib txawv hauv txoj hauv kev muaj txiaj ntsig. Thaum koj ua haujlwm antawv hnab tshuab nrog luam ntawv, lub tshuab luam ntawv qhia txog cov hloov pauv tshiab uas cuam tshuam nrog cov txheej txheem tsim.
Sau npe sau npe thiab Web Alignment
Nyob rau hauv ib lub tshuab txheem, daim ntawv lub vev xaib khiav los ntawm cov chaw tsim khoom nrog ib lub hom phiaj tseem ceeb: qhov tseeb qhov tseeb. Luam tawm, txawm li cas los xij, qhia txog qhov yuav tsum tau ua thib ob uas cuam tshuam nrog thawj - cov qauv luam tawm yuav tsum ua kom raug nrog cov kab txiav, cov kab folding, thiab tuav cov ntsiab lus txuas ntawm lub hnab.
Qhov no yog hu ua luam ntawv sau npe, thiab nws yog ib qho kev sib tw loj tshaj plaws hauv kev sib txuas luam ntawv nrog lub hnab tsim. Ib qho qauv tsim uas zoo nkaus li nyob nruab nrab ntawm daim ntawv tiaj tus yuav xaus li 3 hli tawm - lub hom phiaj ntawm lub hnab tiav yog tias lub vev xaib nruj, pub ceev ceev, thiab folding geometry tsis raug synchronized nrog cov txheej txheem luam ntawv.
Cov tshuab luam ntawv lub hnab feem ntau siv ib qho ntawm ob txoj hauv kev:
Inline luam ntawv:Cov tshuab luam ntawv yog ntsia ncaj qha rau ntawm lub hnab ntim tshuab thiab luam tawm ntawm daim ntawv network ua ntej thawj lub hnab ntim tshuab tau pub. Lub kaw lus tswj kev sau npe siv lub vev xaib - cov ntawv luam tawm txhawm rau txheeb xyuas qhov chaw tsis raug thiab kho lawv raws sijhawm. Txoj kev no yuav tsum tau PLC maub los ntawm kev luam ntawv thiab hnab ntim tshuab kom synchronize ze. Antawv hnab tshuab nrog luam ntawvconfigured li no xav kom nruj kev koom ua ke ntawm cov luam ntawv thiab hnab - kev tswj.
Ua ntej- luam tawm yob:Daim ntawv yog luam tawm ntawm ib qho offline xovxwm thiab tom qab ntawd muab ntim rau hauv ib lub hnab ua ntej - luam tawm yob. Qhov no tshem tawm cov kev sib tw synchronization, tab sis ntxiv cov khoom lag luam cov kauj ruam - ua ntej - cov ntawv luam tawm yuav tsum tau xaj, warehoused thiab tswj - thiab ua rau muaj kev pheej hmoo rau kev sau npe yog tias lub tshuab luam ntawv txiav tsis sib xws rau bagger cov specifications.
Ob txoj hauv kev yog nyob rau hauv kev siv lag luam, thiab txhua tus muaj kev lag luam ua lag luam -offs uas cov neeg tsim khoom yuav tsum tau ntsuas tawm tsam lawv cov khoom lag luam thiab ntim ntau lawm.
Ink Curing thiab ziab lub sijhawm
Thaum tus cwj mem tau siv rau hauv daim ntawv, nws yuav tsum tau qhuav lossis kho ua ntej lub vev xaib dhau los ntawm cov cua sov thiab siab ntawm lub hnab - cov chaw tsim khoom. Cov ntawv ntub dej ntawm daim ntawv lub vev xaib uas tau pub rau hauv lub tshuab folding yuav smear, hloov mus rau cov menyuam, thiab tsim kom muaj kev puas tsuaj zoo.
Hauv flexographic lossis rotogravure luam ntawv ntawm lub hnab ntim tshuab, qhov no feem ntau yog ua los ntawm ib qho ntawm peb txoj kev:
Cua kub kom qhuav:Kev quab yuam cua kub cua tshuab thoob plaws lub vev xaib uas tau luam tawm tshiab kom evaporate cov kuab tshuaj-raws li cov neeg nqa number case. Lub tshuab ziab khaub ncaws yuav tsum tau muab tso rau ze txaus rau qhov chaw luam ntawv kom tus number case tsis qhuav qeeb heev. Slow drying ua rau poob. Lub tshuab ziab khaub ncaws kuj tseem yuav tsum nyob deb txaus kom nws tsis txhob ci cov kua nplaum ua ntej cov kuab tshuaj tag nrho evaporates.
UV curing:Rau UV-kho inks, lub vev xaib luam tawm mus nyob rau hauv lub teeb UV tam sim tom qab lub tog raj kheej lub tswv yim. UV inks kho los ntawm lub teeb tsis yog los ntawm evaporation. Qhov no txhais tau tias cov kauj ruam ziab kom qhuav sai dua thiab nyob ntawm qhov ntsuas kub tsawg dua. Tab sis UV-kho inks ntawm daim ntawv xav tau cov qauv tsim nyog. Yog tias tsis yog, daim ntawv tuaj yeem nkig los yog muaj kev ua tsis tiav thaum nws dhau mus tom qab gluing thiab folding cov kauj ruam.
Combination ziab:Qee lub tshuab siv kev sib xyaw ua ke, tshwj xeeb tshaj yog rau cov kab siab - ceev, qhov twg cov cua kub luv luv tau ua raws li UV kho theem kom ua tiav ziab ua ntej thaj tsam tsim.
Lub tshuab ziab khaub ncaws muaj peev xwm ua rau muaj kev txwv lub cev ntawm kab nrawm. Lub tshuab luam ntawv lub hnab yuav ib txwm khiav qeeb qeeb dua qhov sib npaug uas tsis yog - tshuab luam ntawv rau tib lub hnab hom, vim tias lub vev xaib xav tau sijhawm nyob hauv lub tshuab ziab khaub ncaws. Qhov kev sib txawv ceev no feem ntau underestimated nyob rau hauv kev npaj ntau lawm. Qhov no yog qhov kev txiav txim siab tseem ceeb thaum xaiv ib qhontawv hnab tshuab nrog luam ntawvrau siab - ntim khiav.
Kev xaiv cov ntawv thiab Surface Chemistry
Standard paper bag machines ua hauj lwm zoo nrog uncoated kraft ntawv thoob plaws ntau yam ntawm lub hauv paus luj. Kev luam ntawv, tshwj xeeb tshaj yog siab - zoo ntau- xim txheej txheem luam ntawv, feem ntau yuav tsum tau ntawv nrog ib tug smoother nto - yog coated art paper, coated kraft, los yog tsawg kawg yog ib lub tshuab-tiav (MF) kraft nrog tswj nto roughness.
Kev sib cuam tshuam ntawm daim ntawv nto chemistry thiab number case adhesion yog qhov tseem ceeb tshwj xeeb tshaj yog thaum lub vev xaib luam tawm nkag mus rau qhov chaw nres tsheb gluing. Qee cov coatings thiab inks yog rhiab heev rau pH thiab noo noo cov ntsiab lus ntawm cov nplaum uas tau thov, thiab adhesion tsis ua hauj lwm ntawm cov nplaum nplaum - ntawm lub hnab uas zoo nkaus li zoo tag nrho tsuas yog xoob hauv qab - tuaj yeem taug qab rov qab rau cov teeb meem kev npaj txheej txheem qhia thaum luam ntawv.
Cov neeg tsim khoom lag luam khiav cov kab ntawv luam tawm feem ntau yuav tsum tau siv zog tswj cov ntawv tshwj xeeb tshaj li cov uas tsis tau luam tawm. Kev qhia cov ntawv uas ua haujlwm rau kev luam ntawv thiab kev tsim yog ib qho kev ua haujlwm uas yuav tsum muaj kev sib koom tes ntawm cov ntawv xa khoom, lub tshuab luam ntawv (yog tias siv ua ntej- cov ntawv luam tawm), thiab tus neeg teb xov tooj lub hnab ntim khoom. Antawv hnab tshuab nrog luam ntawvyog li ntawd xav tau kev tswj kom zoo dua ntawm cov khoom tuaj ntau dua li lub tshuab txheem.
Yuav ua li cas txoj kev Mechanics tseem zoo li qub
Txawm hais tias tag nrho cov saum toj no, nws tsim nyog paub meej txog qhov tsis hloov thaum luam ntawv ntxiv.
Lub folding geometry, compression mechanics ntawm lub foob hauv qab, kev tswj nruj ntawm lub vev xaib raws li nws nkag mus rau hauv cov chaw tsim khoom, thiab kev txiav -tawm cov txheej txheem uas cais cov hnab ib tus neeg - tag nrho cov no tseem zoo tib yam rau cov tsis yog - tshuab luam ntawv ntawm qhov sib npaug tsim.
Lub hnab lub cev tseem yuav tsum tau tsim. Tus kov txuas tseem yuav tsum tau tiv thaiv lub filling load. Glued seams tseem yuav tsum tau ua kom tau raws li lub tev lub zog yuav tsum tau rau lub hnab ntim daim ntawv thov. Kev luam ntawv tsis hloov cov kev cai no - nws zaum nrog lawv.
Hauv cov ntsiab lus, qhov no txhais tau li cas rau tus neeg yuav khoom yog tias lub hnab - ua ib feem ntawm lub tshuab tuaj yeem ntsuas tau siv tib cov qauv uas koj xav siv rau cov khoom siv hnab ntawv: hauv qab foob lub zog, gluing system precision, kov qhov sib xws, thiab kev hloov pauv ceev ntawm lub hnab loj. Lub tshuab luam ntawv yog ib qho overlay rau saum cov haujlwm tseem ceeb, tsis yog hloov rau lawv.
Ua qhov kev xaiv zoo rau koj cov khoom kab
Yog tias koj muaj feem pua ntawm cov hnab luam tawm hauv koj cov ntaub ntawv khaws tseg -tshwj xeeb tshaj yog cov khw muag khoom muaj npe, hnab khoom plig lossis pob khoom tshaj tawm- ces lub tshuab luam ntawv lub hnab inline yog tsim nyog rau kev txiav txim siab loj. workflow efficiency ntawm ib qho kev luam ntawv thiab shaping yog ib qho tseem ceeb rau siab - ntim ua haujlwm ntawm tib tus qauv.
Yog tias koj cov khoom tsim tawm feem ntau yog cov hnab ntim yooj yim nrog qee zaus luam ntawv, lossis yog tias koj lub hnab tsim qauv hloov ntau zaus (yuav tsum tau hloov pauv ntau zaus), qhov ua ntej - luam tawm yob txoj kev lossis ib txoj kab luam ntawv ib leeg pub rau lub hnab ntim tshuab yuav muab kev ua haujlwm yooj yim dua.
Lub hauv paus ntsiab lus ua haujlwm ntawm lub hnab ntim tshuab nws tus kheej tsis hloov. Qhov kev hloov pauv dab tsi yog txhua yam nyob ib puag ncig nws - daim ntawv qhia tshwj xeeb, cov txheej txheem tswj hwm, lub qab nthab ceev, thiab kev tswj xyuas qhov zoo yuav tsum tau tswj xyuas cov qauv luam tawm thiab lub hnab ntim ib txhij.
Ntsiab Cai
- Txhawm rau teb cov lus nug thawj zaug ncaj qha: lub hauv paus ntsiab lus tseem ceeb yog tib yam, tab sis qhov kev ua haujlwm tiag tiag diverges hauv ntau qhov chaw tseem ceeb. Cov ntawv sau npe thov kom muaj kev sib koom ua ke uas lub hnab ntim cov tshuab tsis tas yuav tsum tau. Kev ziab thiab kho ntxiv cov txheej txheem thiab kev txwv ceev. Daim ntawv specification nruj considerably. Thiab tag nrho qhov system complexity - hauv kev tswj, kev saib xyuas, thiab tus neeg ua haujlwm txawj - nce ntxiv.
- Cov no tsis yog vim li cas kom tsis txhob luam cov khoom siv yog tias koj lub khw xav tau nws. Tab sis lawv yog cov laj thawj los ntsuas qhov kev txiav txim siab ntawm nws cov ntsiab lus tag nrho, tsis yog qhov yooj yim ntxiv rau lub tshuab uas twb muaj lawm. Thaum hais kom raug, antawv hnab tshuab nrog luam ntawvtuaj yeem xa ob qho tib si siab - lub hnab zoo thiab siab - cov ntawv luam tawm hauv ib qho kev sib koom ua ke - muab rau tus neeg yuav khoom nkag siab txog qhov xav tau ntxiv uas nws tso rau ntawm cov khoom, kev tswj hwm, thiab kev ua haujlwm.
