Yuav Ua Li Cas Qhia Txog Lub Cuab Yeej Rau Lub Siab -Speed, Nruam Roll- mus rau -Roll Kub Embossing Kab?

Ib yob-rau- yob kub embossing kab txuas ntxiv hloov cov yeeb yaj kiab du, tsis muaj cov khoom siv polymer rau hauv qhov tseeb micro- daim ntawv kho qhov muag, xws li qhov ci ci - txhim kho zaj duab xis rau LCD zaub, ntawm qhov ceev ntawm meters ib feeb. Lub hauv paus ntawm lub tshuab no yog thawj rhuab embossing nruas, ib tug loj spinning precision -lub tog raj kheej hauv av uas stamps tus qauv nanoscopic mus rau cov yas ntws. Lub nruas no yog ib qho nkhaus, hloov cua sov platen thiab qhov tshwj xeeb ntawm nws yog cov chav kawm qib siab hauv siab -ceev, ultra-uniform thermal thiab mechanical engineering.

Rotating Heating Platen raws li lub tshuab ua kom sov zoo
Qhov tshwj xeeb ntawm kub embossing nrog lub rhuab platen yob yob nyob rau hauv ib tug siab - yob ceev - mus rau - yob txheej txheem yuav tsum npog peb interdependent domains, uas yog lub thermal uniformity, lub durability nto, thiab cov neeg kho tshuab precision. Nws tsis yog ib qho thaiv zoo li qub tab sis yog ib txoj kab loj loj steel lub tog raj kheej (feem ntau yog 300-600 mm txoj kab uas hla thiab 1-2 m ntev) uas tig mus tas li thaum khaws qhov kub thiab txias ntawm qhov chaw. Cov zaj duab xis polymer yog nias tawm tsam lub nruas, softens thiab yuav siv sij hawm dhau lub microscopic qauv imprinted ntawm lub nruas nto. Txhua qhov kev hloov pauv ntawm qhov kub thiab txias ntawm sab mus rau sab lossis thoob plaws hauv ib puag ncig ua rau qhov tsis sib xws embossing qhov tob, cov khoom tsis lees paub thiab cov kab qis dua.

Thermal Specification: Ntau Cheeb Tsam, Super Uniformity
Lub nruas steel loj yuav tsum nyob rau hauv cua sov kom ua tiav ± 1℃uniformity nyob rau hauv qhov kub thiab txias tshaj tag nrho cov kev khiav hauj lwm dav thiab ib ncig ntawm lub nruas. Koj tsis tuaj yeem muaj qhov sib npaug no nrog ib qho kev tswj tsis tau qhov cua sov.
 

Muaj ob hom cua sov, ua haujlwm ib leeg lossis ua ke:

Embedded cartridge heater zones: Ob peb lub tshuab tso cua sov, txhua qhov ua haujlwm sib cais, yog embedded nyob rau hauv axial bores drilled nyob ze ntawm lub puab nto ntawm lub nruas. Lub nruas tau muab faib ua ntau qhov chaw cua sov (xws li sab laug, nruab nrab, sab xis lossis qhov sib cais ntawm 10-20 aav). Txhua cheeb tsam haum nrog nws tus kheej ntsuas kub (txawm yog thermocouple lossis RTD) thiab kaw lub voj PID maub los. Txoj kev no tso cai rau cov thermal profile kom raug kho raws li qhov ntev ntawm lub nruas kom them nyiaj rau qhov kub poob ntawm lub nruas kawg.

Circulation kub roj system. Lub tshav kub hloov kua (roj) yog circulated los ntawm ib tug helical los yog multi- kis channel nyob rau hauv lub nruas. Cov roj yog rhuab mus rau sab nraud thiab pub rau lub nruas los ntawm kev sib hloov lub union. Cov roj kub kub muaj qhov sib xws zoo heev txij li cov dej txav mus yuav ib txwm nyob nruab nrab ntawm thaj chaw kub. Txawm li cas los xij, lawv muaj lub sijhawm ua haujlwm thermal qeeb dua li lub tshuab hluav taws xob hluav taws xob.

Rau cov ntawv thov raug tshaj plaws, hybrid system yog siv. Cartridge heaters pab ceev ceev, localized tswj thaum lub roj voj voj voog muab kev ruaj ntseg kub. Nyob rau hauv txhua rooj plaub, lub thermal expansion ntawm lub nruas (steel expands txog 11-13 μm / m· degree) yuav tsum tau txiav txim siab rau tus tsim ntawm embossing qauv. Yog tias tus qauv raug txiav hauv lub nruas txias, nws yuav hloov suab thaum coj mus rau qhov kub thiab txias hauv kev ua haujlwm. Yog li lub nruas yog machined ntawm kev ua hauj lwm kub los yog tus qauv yog kho rau thermal expansion nyob rau hauv lub xam tsim.

Surface Spec : Ntev Ntev Tsis Taus -Tag Txheej
Sab nrauv ntawm cua sov nruas yog cov cuab yeej ua haujlwm. Nws yuav tsum tau muab tso rau hauv daim iav tiav (Ra <0.1 μm) thiab coated nrog ib txheej nyias, tawv thiab ruaj khov. Cov txheej txheej yuav tsum tau ua kom lub siab tsis tu ncua ntawm cov yeeb yaj kiab polymer txav, tiv thaiv cov tshuaj lom neeg los ntawm cov khoom siv ntxiv hauv zaj duab xis, thiab tso cai yooj yim tso tawm ntawm cov yas embossed yam tsis muaj nplaum.

Ob qhov kev thov ntau tshaj plaws yog:

Pob zeb diamond-Zoo li Carbon (DLC) Ib qho nyuaj, amorphous txheej ntawm carbon nrog lub thickness ntawm 1-3 μm. DLC muaj kev sib txhuam tsawg heev (coefficient ntawm kev sib txhuam<0.1), good wear resistance and great heat conductivity. It is perfect for high speed, high pressure embossing lines.

Chromium Nitride (CrN): Ceramic txheej, tso los ntawm lub cev vapor deposition (PVD). CrN muaj qhov nyuaj heev (txog 2000 HV), zoo oxidation tsis kam mus txog 700℃thiab tsis yog - nplaum nto. Nws yog feem ntau thicker dua DLC (5-15 μm) thiab yog haum rau ntau aggressive films ntxiv txheej txheem.

Cov txheej yuav tsum tau siv tas li nyob ib ncig ntawm tag nrho lub voj voog thiab ntev ntawm lub nruas. Ib qho kev tsis sib xws hauv cov txheej thickness los yog kev ua raws cai yuav ua rau muaj kev sib tsoo hauv zos lossis hnav thaum ntxov. Cov lus qhia tshwj xeeb yuav tsum qhia cov khoom siv txheej, qhov tsawg kawg nkaus hardness (piv txwv li> 1500 HV), thickness kam rau ua (xws li ± 10%) thiab cov txheej txheem adhesion test (xws li khawb los yog daim kab xev tev).

Mechanical Spec: Rotary Union, Sib npaug thiab Runout
Lub nruas spinning ntawm qhov ceev heev. Pua pua ntawm cov kiv puag ncig ib feeb kab tias. Yuav kom sib npaug. Txhua qhov kev tsis sib haum xeeb ua rau muaj kev vibration uas xa mus rau cov yeeb yaj kiab embossed tsim cov qauv pom kev cuam tshuam (los yog cov neeg kho tshuab chatter). Cov lus qhia tshwj xeeb yuav tsum qhia qhov ntsuas qhov ntsuas qhov ntsuas, feem ntau G2.5 lossis siab dua rau ISO 1940-1.

Runout kam rau ua yog qhov tseem ceeb sib npaug. Rau siab precision micro- kho qhov muag embossing tag nrho qhia runout (TIR) ​​ntawm sab nrauv ntawm lub nruas txheeb ze rau lub axis ntawm kev sib hloov ntawm lub nruas yuav tsum tsawg tshaj li 5 μm. Qhov no txhais tau hais tias qhov chaw nruab nrab ntawm lub nruas thiab lub txee siab rau cov menyuam yog ib txwm zoo ib yam thiab yog li qhov tob ntawm qhov embossing yog ib txwm zoo ib yam thoob plaws qhov dav ntawm zaj duab xis.

Qhov zoo tshaj plaws incandescent nruas yog ib tug nkhaus, rotating anvil, ib tug zoo kawg nkaus kub, zoo kawg nkaus tus menyuam stamping ib lab minuscule qauv ib feeb. Tab sis tag nrho cov thermal thiab mechanical perfection yog tsis muaj txiaj ntsig yog tias cov cua sov sab hauv lossis cov sensors tsis tuaj yeem txuas ncaj qha. Lub union rotary (los yog hu ua revolving joint) yuav tsum:

Kov kub kub hluav taws xob circuits (cartridge heaters) los yog roj kub nyob rau hauv siab (civ tshuab) tsis muaj to.

Khiav ntawm tag nrho rpm, tsis muaj kev sib txhuam thiab hnav.

Txhawb ntau- cheeb tsam cua sov tswj thoob plaws ntau txoj kev ywj pheej.

suav nrog ib lub nplhaib ntiv nplhaib rau thermocouple lossis RTD cov cim.

Silver-plated contacts los yog kua- txhuam hlau yog muab rau cov khoom siv hluav taws xob cua sov hauv ntau- channel rotary unions kom ntseeg tau tias tsis muaj hluav taws xob tsis zoo thiab lub neej ua haujlwm ntev. Rau cov roj-rhuab nruas, ob npaug -flow rotary union yog ua hauj lwm, nrog cov neeg kho tshuab ntsaws ruaj ruaj (xws li carbon- graphite vs carbide), ntsuas rau qhov siab tshaj plaws kev khiav hauj lwm kub (feem ntau mus txog 250℃rau hluavtaws roj) thiab siab (10-20 bar).

Xaus: Lub Pinnacle ntawm Platen Design
Lo lus kawg hauv platen engineering yog qhov tshwj xeeb ntawm lub tshuab cua sov embossing rau lub siab - yob ceev - rau - yob kub embossing tshuab. Nws yog ib qho ceev, ultra-paj meej rotating thermal thiab mechanical ntaus ntawv uas huab hwm coj- tsim cov qauv tsis pom ntawm cov optics niaj hnub- los ntawm qhov ci- txhim kho cov yeeb yaj kiab rau cov duab, kom pom kev - cov ntawv qhia rau cov teeb pom kev zoo. Tag nrho cov tsis xws li ± 1℃thermal uniformity,<5 μm runout tolerance and durable DLC coating must be defined, validated and recorded. The most advanced production equipment are constructed on the most completely engineered spinning hot cylinders. A well-designed heated platen does more than just emboss plastic, it provides a profitable, high-yield, continuous production line. Compromises in the specification immediately result in rejected film, down time and lost income.
