Daim duab xim ntawm qhov plaub xim version ntawm A, B, C, thiab D tuaj yeem sib hloov tau raws li tej yam kev mob.
Thib ob, kev nruj nruj ntawm kev tswjhwm
Thaum lub caij ua ntej txog kev kaw lus, cov ntawv lossis zaj duab xis yuav tsum tau tswj kom muaj kev nruj thaum lub sij hawm siv ntau hom kev luam xim los yog thaum lub sij hawm xa xov. Qhov nro loj heev los ua rau cov pob txha wrinkles, thiab qhov nro yog tsawg dhau los ua rau tom qab lub pob tw. Hauv ntej, qhov kev hloov ntawm qhov nro yuav cuam tshuam rau qhov tseeb ntawm cov pov thawj, yog li cuam tshuam rau qhov kev ruaj ntseg ntawm qhov zoo ntawm cov luam, yog li qhov nyuaj yuav tsum tswj.
1. Nias kev tswj ntawm ntau qhov chaw ntawm lub tshuab luam ntawv
(1) Kev tswj kom nruj ntawm txoj hliv pub rau ntawm kev pub rub tawm
Vim qhov kev txiav txim ntawm cov menyuam rub tawm, cov khoom siv luam tawm yog rho tawm ntawm cov khoom noj ntawm ib qho kev ceev thiab nro thiab xa mus rau kev luam ntawv. Qhov nro ntawm qhov no yog siab dua qhov kev nruj ntawm qhov kev sib tshuam, thiab qhov nruj feem ntau tswj tau lub tsheb nres nrog daim ntawv pub mov. . Nws yog qhov zoo paub tias txoj kab uas hla ntawm txoj haujlwm yog maj mam txo tib lub sijhawm. Nyob rau hauv xyoo tas los, vim qhov nce ntawm kev ceev, kev siv cov ntaub ntawv muaj ntau ntau, thiab cov coil diameter tau hloov ntau heev. Yog li ntawd, kev ceev faj siv cov cav tsheb qub uas siv yav dhau los tsis zoo siv cov khoom pov thawj zoo. Vim li no, kev siv txoj kev tswj tsis pub siv, tshwj xeeb tshaj yog siv cov kev ntsuas nrawm nrog cov ntaub ntawv tswj ua ib qho kev tsim nyog. Cov kev paub tias muaj xws li lub caij nplooj ntoo hlav tawm thiab hom kab mob sib kis mus rau micro. Cov neeg tsav tsheb tau siv tau los ntawm lub hnub nyoog thaum ntxov thiab pheej yig, tab sis lub qhov taw qhia qhov teeb meem tsis yog. Yog li ntawd, muaj ntau hom ntaub ntawv. Lub tshuab nqus hlau nplaum siv lub tshuab ua kom sib txawv raws li lub nruab nrab ntawm kev sib txuam los ua kom muaj lub zog siv lub dag zog tam sim no, thiab siv dav vim nws txoj kev ua kom muaj teebmeem ntawm lub zog tamsim no. Cua nres, tab sis qee cov tshuab luam ntawv tau siv ntau dua, lawv maj mam hloov los ntawm cov cuab yeej loj sib nqus hmoov txhuam ntawm cov pa roj carbon monoxide vim muaj cov yam ntxwv tsis muaj linear thiab cov ris tsho loj. Qhov nro ntawm cov feedstock yog txiav txim siab los ntawm cov nram qab no yam: 1 hloov tensile vim tsis sib npaug; 2 slippage ntawm cov khoom thiab txawm qeeb; 3 rolls tsis loaded, cov khoom siv thiab ncej ntawm eccentric; 4 xa cov cuab yeej hauv kev sib hloov Tus hloov peripheral ceev hloov; 5 qhov kev tawm tsam ntawm kev sib raug rau cov tub-ntxhais thiab lub tshuab txiav thaum khaws daim ntawv; 6 qhov sib npaug ntawm txhua tus menyuam yaus tsis txaus.
Feem ntau ntawm cov kev hloov saum toj no tshwm sim nyob rau ib lub sijhawm luv luv, thiab txhua yam kev hloov ntawm qhov nro tau xa mus rau lub tuam tsev luam ntawv. Los ntawm qhov pom ntawm cov neeg ua haujlwm, nws yuav tsum raug sau tseg tias cov tswv yim thiab kev ua yuam kev ntawm qhov kev pabcuam rau cov menyuam yaus thiab lub tsho muaj laj kab yog ob qho tibsi ua rau muaj kev nce siab, thiab qhov tshwjxeeb, qhov tsis sib haum ntawm ob peb kilograms lossis tsawg dua yuav tsum tsis raug ignored.
(2) Hloov thiab tswj kev sib nraus ntawm kev sib tshuam rau cov tub sab thiab cov phaj rau cov menyuam (traction)
Cov kev sib tshuam hauv kev sib tsoo hauv cov xovxwm gravure feem ntau yog nyob rau ntawm thawj phaj cov menyuam thiab muab nrog ib qho kev ceev nrawm synchronizing mechanism. Qhov no txawv ntawm qhov teeb meem noj, lub taub tsis hloov, yog li qhov nro tswj tau los ntawm lwm cov hauv paus ntsiab lus.
Cov ntawv luam tawm yog cov khoom ua ywj siab thiab yas ua khoom zoo li qub, thiab luam ntawv ua tiav tsis pub dhau lub tsho tshaj tawm. Yog li, qhov nro yog tswj raws li txoj cai ntawm elasticity. Qhov no yog to taub cov yam ntxwv ntawm cov khoom sib txawv. Yuav kom tau txais tib qho kev loj hlob thaum siv, qhov nro yuav txiav txim siab hauv ntau qhov kev sib piv ntawm qhov dav thiab thickness ntawm cov khoom.
Muaj ob txoj hauv kev tau txoj kev nruj:
a. Ua rau ntawm txoj kab uas hla ntawm tus pinchler me ntsis; kho cov xov tooj ntawm revolutions ntawm tus pinch roller. Lub sij hawm yuav tsum muaj cov ntaub ntawv luam kom ncav cuag lub nro ntawm lub xeev tsis muaj nrawm hauv kev khiav hauj lwm yog qhov kev txiav txim siab ncua sij hawm ntawm qhov kev sib tw ntawm lub siab thiab cov nqi txo tus nqi raws li lub sijhawm tsis tu ncua, uas yog feem ntau hu ua tensile control . Rau hauv daim ntawv sau ntawm gravure nias: ntawm daim ntawv pub rub yob thiab lub phaj yob, qhov nro ntawm lub phaj yob, phaj yob thiab kev kos cov yuj nruas yog raws li txoj cai no.
b. Ntxiv rau qhov no, nws muaj ib txoj hauv kev tswj qhov kev nruj ntawm tus paim tub ntxhais kawm ntawv. Cov ntsiab cai yog tias qhov nro hloov nrog qhov kev hloov ntawm qhov nyhav thiab qhov chaw ntawm qhov hnyav. Nyob rau txhua qhov teeb meem, cov phaw pendulum muaj cov nyhuv ntawm qhov kev hloov ntawm qhov nro, thiab cov phom pendulum feem ntau txais kev yuam kev lawm. Me me, qis-hauv siab, lub cev kub hnyav, thiab lub dav hlau loj (xws li cov txhuas hauv cov pob txha) yog tshem tawm raws li no los ntawm lub sij hawm luv luv ntawm lub feedstock thiab qhov kev sib tw rub kom txo me me nro hloov. Txoj kev no tseem tuaj yeem txo kev puas tsuaj thaum khaws cov ntaub ntawv.
(3) Tension tswj ntawm qhov chaw txais traction
Los ntawm lub phaj dob mus rau qhov txais tau kab rau ziab, qhov deb yog feem ntau nce. Vim lub ziab thiab cua sov, kev txuas ntxiv ntawm lub tsheb hloov, ua rau cov khoom siv hloov thiab kev qoj zuj zus, uas yog vim li cas rau qhov tsis muaj tseeb tshaj tawm. Yog li, raws li nrog cov seem traction seem, yuav tsum muaj kev tswj kom zoo dua thiab ntau dua. Cov ntaub ntawv uas tsis tshee hnyav rau daim ntawv ultra-thin kuj tseem raug rau lub adhesion ntawm cov hluav taws xob zoo li qub los ntawm cua cua tshuab los ntawm lub tshuab ziab khaub ncaws, uas ua rau me hloov, uas yuav tsum raug xam tias yog.
(4) Kev tswj kev nruj
Lub nruj tswj ntawm qhov coiling feem (nruab nrab ntawm cov kev sib tw uas tau txais thiab cov ntawv txais nyiaj) kuj yog ib qho teeb meem tseem ceeb. Hauv ntu no, cov ntaub ntawv luam tawm yog siv qhov khoom kawg thiab xa mus rau lwm txoj haujlwm ntxiv ntawm kev sib txuas, kev txiav, thiab lub hnab.
Tib lub sijhawm, yuav tsum tau saib xyuas kom tsis txhob khawb thiab ntsws ntawm qhov khoom tsis zoo. Nws yog tsim nyog sau cia tias cov yas films thiab txhuas foils, kev saib xyuas yuav tsum tau coj los tiv thaiv variations hauv thickness. Qhov no tsis yog ib qho teeb meem ntawm kev nrhau npaum li cas. Nws yog ib qho tseem ceeb kom kho qhov nro thaum nce lub pob ntawm lub kauj voj, txawm tias nws yog kho nrog ib qho kev nruj nruj los yog kev nruj seem.
Muaj ob txoj kev tsav tsheb nyob rau hauv seem ntu: qhov chaw tsav tsheb thiab chaw tsav tsheb. Txawm hais tias lub chaw nruab nrab tsav hom siv ntau tshaj, qhov kev tshem tawm ntawm qhov chaw nqos kuj muaj cov khoom zoo, thiab nws yog qhov zoo thaum cov yob ceev nrooj. Yog li, nws yog siv ntau yam hauv qee lub lag luam. Sib piv nrog cov khoom noj, qhov kev txais yuav tsum tau them ntau dua rau qhov kev sib taper thiab qhov ua yuam kev raug mob ntawm inertia. Lub chaw tsav tsheb yog kom ncaj qha mus nqa cov khoom ntawm daim raj xa ntawv. Yav tag los, kev siv txhuam kev tiv thaiv siv tau. Tam sim no, qhov siab, qhov kev siv hluav taws xob thiab kev siv hluav taws xob ua tau zoo yog siv los ua. Qhov txais thiab txoj hlua khi yog raws li nram no: 1 siv cov hlau nplaum sib txig sib luag; 2 siv lub cav qeeb zog; 3 siv lub cav xaib DC.
Sib nqus hmoov hlau clutch tau kev ua tau zoo heev ntawm tus nqi qis; torque lub cev tsis yooj yim rau siv thaum lub qhov tsis sib thooj ntawm kev sib hloov zoo heev; DC lub cav siv rau lub peev xwm loj thiab cov ntawv tsis zoo noj. Cov lus 1 teev cov nqi ntawm qhov nro ntawm ob peb lub substrates nyob rau ntau qhov chaw hauv xovxwm.
2. Taper nrawm
Feem ntau, qhov kev nruj yog coj los ntawm qhov nro tsis tu ncua, thiab raws li qhov yob tsub ntxiv, lub caij ua ntu zus rau cov khoom siv sab hauv loj, ua rau cov nplais, uas yog, thau tawm. Tsis tas li ntawd xwb, vim yog lub ntsws ntawm cov khoom thiab lub siab ntawm huab cua mus rau qhov chaw, cov khoom yog crushed los yog extruded laterally, resulting nyob rau hauv ib tug thiaj li hu xyoob shoot phenomenon. Wrinkles tshwm sim nyob ze ntawm lub hauv paus, ua qhov tsis ncaj ncees. Yuav kom daws tau cov teeb meem, qhov nro yuav tsum maj mam txo thaum lub qhov cua ntawm lub voj voog loj zog, uas yog, qhov siv ceev nro. Qhov pib thaum nrawm ntawm lub sij hawm ntawm qhov kev txiav txim siab yuav txiav txim siab qhov nro ntawm qhov xaus ntawm qhov cua. Daim ntawv txo qis qis hu ua taper. Xws li, feem ntau yog siv taper ntawm 10% mus rau 50%. Piv txwv li, nrog 30% taper; uas yog, pib nrog ib tug nro ntawm 10 kg, qhov nro yog tawm los ntawm 7 kg. Qhov piv ntawm kev hloov nyob rau ntawm lub sij hawm no yog txawv nyob ntawm seb cov khoom ntawm cov khoom thiab cov mechanism. Cov chaw tsim tshuaj yuav tsum sim ntau hom kev xeem curves rau kev tswj cov khoom. Kev hloov.
3. Nyiaj Inertia
Lub npe hu ua inertia compensation yog los tiv thaiv qhov kev hloov hauv nro los ntawm lub hwj chim thaum lub sijhawm pib ntawm lub tshuab, thaum lub sijhawm ua haujlwm, thaum qhov kev hloov pauv, lossis thaum tus ceev xwm ceev ncav cuag lub sijhawm ceev tshaj. Hauv kev xyaum, lub sij hawm nonlinear yog nonlinearly proportional rau lub taub thiab cov khoom ceev yog proportional rau cov khoom dav. Lub chaw luam ntawv siv cov qauv mis los laij nruab nrab ntawm cov nqi nruab nrab thiab txiav txim siab cov nyiaj nkhaus kom ua tus coj.
Thib peb, luam tawm kev tswj siab
Lub zog ntawm kev sib cuam tshuam ntawm lub cev nqaij daim tawv embossing thaum lub sij hawm luam ntawv yog hu ua lub siab ceev printing. Gravure yog tib yam li lithographic printing thiab embossing. Nws yog ib qhov tsim nyog siv lub tshuab luam ntawv kom hloov cov duab nrawm ntawm lub phaj luam tawm mus rau cov ntawv luam tawm substrate. Kev luam tawm tsis yog tsuas yog siv tau rau txoj kev luam ntawv xwb, tab sis feem ntau kuj txiav txim siab zoo ntawm cov luam ntawv. Yuav kom txhim kho tau qhov zoo ntawm cov pob zeb, lub siab yuav tsum tswj tau, ces yam yuav tsum tau txiav txim siab los mus txiav txim siab txog kev luam ntawv siab:
