Kev tshuaj xyuas qhov ua rau thiab kev daws teeb meem ntawm kev tsis sib xws hauv cov txheej txheem slitting ntawm cov yeeb yaj kiab loj yob
I. Lub hom phiaj thiab qhov tseem ceeb ntawm Slitting Loj zaj duab xis yob
Cov txheej txheem slitting yog ib kauj ruam tseem ceeb uas ua rau kev sib txuas ntawm cov tuam txhab ua yeeb yaj kiab thiab cov khoom lag luam qis thiab cov lag luam sib xyaw. Nws lub luag haujlwm yog los txiav cov yeeb yaj kiab loj loj rau hauv qhov ntev raws li cov neeg siv khoom xav tau raws li lawv cov kev xav tau.
Thaum lub sij hawm slitting thiab unwinding txheej txheem, qhov zoo ntawm tag nrho cov loj zaj duab xis yob tuaj yeem raug kuaj xyuas. Los ntawm leveraging lub jitter thaum slitting, tej yam tsis xws luag nyob rau hauv lub loj zaj duab xis yob, xws li me ntsis wrinkles, yuav kho. Cov txheej txheem no tseem ua kom ntseeg tau tias cov yeeb yaj kiab slitted tuav lub xeev zoo winding, ua tau raws li qhov yuav tsum tau ua kom haum rau kev luam ntawv.
Raws li GB / T10004-2008 tus qauv, qhov yuav tsum tau ua rau qhov tsis sib xws ntawm qhov kawg ntawm lub ntsej muag ntawm cov yeeb yaj kiab yob yuav tsum tsis pub tshaj 3 hli. Qee cov yeeb yaj kiab yuav muaj qhov xav tau ntau dua, feem ntau tsis tshaj 2 hli.
II. Cov yam ntxwv cuam tshuam rau qhov tsis sib xws ntawm Slitting End Face
Lub flatness ntawm zaj duab xis yob kawg lub ntsej muag yog ib qho tseem ceeb qhia txog qhov zoo ntawm zaj duab xis. Nws tuaj yeem cuam tshuam rau kev ruaj ntseg ntawm cov khoom lag luam zoo hauv kev luam ntawv thiab cov txheej txheem sib xyaw, xws li kev luam tawm kom raug, tsis zoo, thiab ntug adhesion.
Lub ntsiab yog vim li cas rau lub unevenness ntawm lub slitting kawg lub ntsej muag yog raws li nram no:
Kev cuam tshuam ntawm qhov zoo ntawm cov yeeb yaj kiab loj yob nws tus kheej:
Tsis zoo ntawm cov zaj duab xis loj yob, xws li loj thickness variations, wrinkles, thiab loj longitudinal mos wrinkles, txawm tias tom qab slitting thiab rewinding, tsis tuaj yeem ua tiav qhov pom kev zoo. Slitting tuaj yeem daws teeb meem hauv zos tab sis tsis tuaj yeem hloov cov teeb meem tag nrho. Txhawm rau kom tau txais qhov zoo nkauj, kev hloov kho yuav tsum tau ua nyob rau hauv ob qho tib si txheej txheem slitting thiab qhov zoo ntawm cov yob zaj duab xis loj. Tsuas yog thaum qhov zoo ntawm cov yeeb yaj kiab loj yob ua tau raws li qhov yuav tsum tau ua kom pom kev txaus siab zaj duab xis yob tau los ntawm slitting.
Kev cuam tshuam ntawm Slitting Txheej Txheem Kev Ua Haujlwm:
Ntau hom slitting tshuab, hom zaj duab xis, thiab kev sib txuas ntawm cov yeeb yaj kiab sib xyaw muaj qhov sib txawv, txoj hauv kev, thiab qhov tseem ceeb rau cov txheej txheem slitting. Kev ua tau zoo ntawm cov khoom siv thiab cov khoom siv hauv cov yeeb yaj kiab muaj kev cuam tshuam loj rau qhov zoo ntawm cov yeeb yaj kiab slitting, thiab, yog li ntawd, ib qho loj-fits-txhua txoj hauv kev tsis tuaj yeem siv rau tag nrho cov yeeb yaj kiab yob.
Cov nyhuv ntawm qhov zoo ntawm cov ntawv Core:
Qhov zoo ntawm cov ntawv tseem ceeb ncaj qha cuam tshuam rau qhov zoo slitting. Cov yam ntxwv xws li qhov ncaj, concentricity, lub zog, thiab qhov smoothness ntawm daim ntawv tseem ceeb heev. Wide paper cores yog qhov nyuaj dua los xyuas kom meej qhov ncaj thiab concentricity. Cov ntawv zoo zoo yuav tsum muaj qhov ncaj hauv 0.004% thiab qhov roughness tsawg dua 0.2um. Daim ntawv cores nrog qhov dav siab tshaj 1.8m yuav tsum tau kuaj xyuas tshwj xeeb, thiab tsis pub muaj cov dents lossis kev puas tsuaj ntawm cov ntawv tseem ceeb, vim tias nws tuaj yeem ua rau muaj kev hloov pauv hauv qhov tsis sib xws, cuam tshuam rau qhov sib npaug ntawm lub ntsej muag kawg.
Kev cuam tshuam ntawm Mechanical Factors ntawm Slitting Equipment:
Qee cov yeeb yaj kiab yob muaj cov cai nruj rau qhov sib npaug ntawm lub ntsej muag kawg. Mechanical yam ntawm cov cuab yeej slitting, xws li kev sib luag ntawm ntau yam chais hauv ntu slitting thiab kab rov tav sib dhos ntawm cov khoom siv thiab hauv av, yog qhov tseem ceeb. Kev tshuaj xyuas tsis tu ncua thiab kev saib xyuas ntawm cov cuab yeej yog tsim nyog los xyuas kom meej kev ua haujlwm zoo. Kev tswj xyuas kev sib koom tes ntawm kev sib tw winding clearances thiab nro yog qhov tseem ceeb, vim tias tsis sib xws thaum lub sij hawm unwinding thiab winding tuaj yeem ua rau lub ntsej muag tsis sib xws. Kho lub kaum sab xis ntawm zaj duab xis thiab lub siab rau cov menyuam thiab txo cov cua nkag tuaj yeem txhim kho qhov sib npaug ntawm lub ntsej muag kawg. Txawv diameters ntawm zaj duab xis yob yuav xav tau kev sib txawv nro hloov thaum lub sij hawm slitting txheej txheem.
Ua kom tsis sib xws los ntawm Electrostatics:
Thaum qhov kev tiv thaiv nto ntawm ib yam khoom tshaj 10 ^ 15 ohms, nws yog suav tias yog ib qho insulator tsis muaj peev xwm los tiv thaiv zoo li qub. Cov yeeb yaj kiab nws tus kheej thiab cov khoom zoo li qub thaum lub sijhawm ua haujlwm siab tuaj yeem ua rau zaj duab xis adhesion lossis drifting, uas ua rau lub ntsej muag tsis sib luag. Qhov kev tiv thaiv nto ntawm zaj duab xis yuav tsum yog qhov zoo tshaj plaws hauv qab 10^13 txhawm rau txo cov teebmeem ntawm hluav taws xob zoo li qub thaum thauj mus los ntev.
Lwm yam cuam tshuam rau Cov tsos zoo:
Cov xwm txheej xws li kev cob qhia ib puag ncig, kev nyab xeeb, txoj kev tswj hwm, thiab cov neeg ua haujlwm lub siab lub ntsws thiab lub siab xav kuj tuaj yeem cuam tshuam qhov zoo ntawm cov khoom slitting.
III. Cov tsos mob yuav tsum tau thaum xaiv zaj duab xis yob
Thaum yuav cov yob zaj duab xis, ntxiv rau kev lees paub cov ntawv sau sab nraud, cov lus qhia tshwj xeeb, hnub tsim khoom, thiab lub neej txee, yuav tsum tau saib xyuas cov ntsiab lus hauv qab no hais txog cov tsos ntawm cov yob zaj duab xis:
Tsis hnov tsw:
Raws li cov qauv kev nyab xeeb thiab kev nyiam huv ntawm cov zaub mov, cov yob zaj duab xis yuav tsum tsis txhob muaj ntxhiab tsw, txawm tias feem ntau hais txog "cov ntxhiab tsw ntxhiab." Cov ntxhiab tsw zoo li no tuaj yeem cuam tshuam rau kev tiv thaiv saj ntawm cov khoom ntim khoom ntim.
Cov xwm txheej saum npoo:
Cov yeeb yaj kiab yob qhov chaw yuav tsum tsis txhob muaj cov kab mob hnyav, wrinkles, lossis kev nyuaj siab. Cov teeb meem no qhia txog qhov tsis sib xws thiab tuaj yeem ua rau lub ntsej muag tsis sib luag, tsis raug overprinting, misalignment hauv lamination, thiab txheej nrog npuas lossis qhov chaw uas ploj lawm.
Tsis zoo cuam tshuam rau cov khoom hauv qab:
Cov yeeb yaj kiab yob lub ntsej muag yuav tsum tsis muaj cov ntsiab lus siv lead ua, cov pob dub, npuas, av, roj stains, lossis ib qho tsis xws luag uas tuaj yeem cuam tshuam cov tsos zoo thiab lamination zoo ntawm cov khoom qis.
Internal thiab External Tightness:
Cov yeeb yaj kiab yob yuav tsum tsis txhob muaj qhov xoob sab hauv thiab sab nraud nruj. Artificially ntxig cov ntawv xov xwm thaum lub sij hawm slitting vim cov khoom tsis sib xws kuj tsis tso cai. Lub hnub qub-zoo li wrinkles tshwm sim los ntawm sab hauv looseness thiab sab nraud nruj kuj raug txwv. Cov teeb meem no tshwm sim los ntawm kev tswj tsis zoo ntawm kev sib tsoo thaum lub sij hawm slitting, kev tswj tsis txaus ntawm kev hloov siab, tsis sib xws zaj duab xis thickness, khoov ntawm cov ntawv tseem ceeb, thiab kev sib cuag ntawm cov menyuam tsis sib haum.
IV. Cov lus pom zoo
Teem tsim nyog txheej txheem Parameter:
Cov ntaub ntawv sib txawv thiab cov qauv sib xyaw xav tau cov txheej txheem slitting sib txawv. Kev nkag siab txog cov yam ntxwv tseem ceeb thiab cov yam ntxwv ntawm cov khoom siv slitting yog qhov tseem ceeb. Tsis tas li ntawd, kev nkag siab txog lub luag haujlwm ntawm zawv zawg platform hauv slitting yog ib qho tseem ceeb, vim nws txhawb nqa cov menyuam perforation thiab tuaj yeem siv rau sab laug thiab txoj cai viav vias. Yog li ntawd, zawv zawg platform yuav tsum tau yooj; txwv tsis pub, cov zaj duab xis slitted yuav tsis sib npaug, nrog lub ntsej muag jagged kawg.
Xaiv Txoj Cai Slitting Blades:
Cov hniav yuav tsum tau xaiv raws li lub thickness ntawm cov zaj duab xis slitting thiab cov qauv ntawm cov rewind. Rau cov ntaub ntawv nrog cov yeeb yaj kiab tuab hauv qab 70um thiab cov qauv sib xyaw, ob chav tuaj yeem siv tau. Cov hniav no yog softer thiab haum rau slitting thinner cov ntaub ntawv. Rau cov yeeb yaj kiab thicknesses siab tshaj 70um, ib leeg hniav nrog lub zog rigidity yog nyiam. Thaum txhim kho cov hniav, lawv yuav tsum tau muab tso rau ntawm lub kaum sab xis 45 degree. Lub kaum sab xis loj tuaj yeem ua rau kev siv tsis zoo ntawm cov hniav, thaum lub kaum sab xis me tuaj yeem ua rau tsis tiav slitting nrog jagged npoo.
