Kev daws teeb meem rau cov teeb meem ntawm kev sib txawv thiab pom Jamming hauv ntawv yob Slitting txheej txheem

Hauv papermaking, ntim, luam ntawv, thiab lwm yam, kev ua haujlwm ruaj khov ntawm daim ntawv yob slitting tshuab ncaj qha cuam tshuam rau kev tsim khoom thiab cov khoom tiav tiav. Txawm li cas los xij, qhov sib txawv thiab cov hniav jagged hauv cov txheej txheem ntawm kev ua haujlwm ntawm cov khoom siv feem ntau ua rau cov khoom pov tseg, cov khoom siv poob qis thiab txawm tias muaj kev nyab xeeb. Raws li kev lag luam kev coj ua thiab cov hauv paus ntsiab lus, daim ntawv no tau txheeb xyuas cov hauv paus hauv paus ntawm cov teeb meem no los ntawm plaub qhov loj: cov qauv siv tshuab, cov khoom siv, tswj cov logic thiab kev ua haujlwm tshwj xeeb, thiab muab cov kev daws teeb meem sib xws.

1.Dynamic Calibration ntawm cov menyuam tshuab
Cov menyuam yaus yog qhov tseem ceeb ntawm cov ntawv xa khoom, nws qhov kev teeb tsa raug ncaj qha cuam tshuam rau qhov ncaj ntawm kev faib khoom. Cov ntaub ntawv ntawm lub zog tshiab roj teeb zaj duab xis chaw tsim tshuaj paus qhia tau hais tias thaum qhov kev ua yuam kev theem ntawm lub slitting rollers tshaj 0.05 mm / m, qhov tshwm sim ntawm cov khoom sib txawv hauv siab - ceev slitting nce peb npaug. Cov kev daws teeb meem suav nrog:

• Kev Ntsuas Ntsuas Ntsuas: Kev ntsuas qhov ntsuas qhov sib npaug ntawm cov lus qhia thiab cov ntawv yob yog ua txhua hli siv laser interferometer lossis hluav taws xob qib kom paub tseeb tias qhov yuam kev tsis tshaj 0.02 mm / m.
• Kev saib xyuas cov kabmob: Tshawb xyuas cov kabmob tshem tawm txhua 500 teev ua haujlwm, hloov cov kabmob hnav, thiab siv cov roj lubricating kub (xws li Molykote X-5-1) kom txo kev sib txhuam.
• Kev ntxuav lub tog raj kheej: txhua lub limtiam siv isopropyl cawv-soaked non- ntaub ntaub los ntxuav lub nruas roj thiab cov ntawv khib nyiab, tiv thaiv adhesion los ntawm kev sib txawv.

2.Txhim kho cov cuab yeej txiav tshuab
Cov xwm txheej ntawm cov cuab yeej cuam tshuam ncaj qha rau kev txiav kev ua haujlwm thiab kev ntxhov siab ntawm cov ntawv. Nyob rau hauv ib rooj plaub uas muaj kev lag luam ntim, 2℃sib txawv ntawm lub kaum sab xis ntawm cov hniav nce kev ntxhov siab ntawm daim ntawv los ntawm 40%. Cov kev ntsuas tshwj xeeb suav nrog:

• Hniav mounting calibration: siv lub kaum ntse ntse ntsuas los xyuas kom meej cov hniav sib npaug sib npaug sib npaug tsawg dua lossis sib npaug li 0.1℃thiab hniav qhov tob qhov yuam kev yog tsawg dua 0.05 hli.
• Dynamic nro them nyiaj: Nruab lub siab pas nrig tom qab hniav thiab kho qhov siab ntawm lub sijhawm siv lub tshuab pneumatic lub tog raj kheej siab sensor (ntau: 0-10 bar) kom ntseeg tau tias daim ntawv tsis sib xws.
• Pom Hniav Tension Optimization optimization: siv lub tshuab sawing yuav tsum maj mam kho qhov nro hloov pob qhov rooj kom txog thaum cov hniav vibrates ywj siab yam tsis muaj zawv zawg, kev vibration zaus yog 50 - 80 Hz.

1.Paper zoo tswj
Cov khoom tsis xws luag yog qhov ua rau muaj kev tsis ncaj ncees. Nyob rau hauv ib rooj plaub ntawm lub tsev luam ntawv, qhov yuam kev nce 65% thaum lub yob dav sib txawv tshaj ± 2 hli. Cov kev daws teeb meem suav nrog:

• Kev soj ntsuam tus neeg muag khoom: Xav kom tus neeg muag khoom muab daim ntawv rolls motion balance test report kom paub meej tias qhov kawg pulses runout Tsawg dua lossis sib npaug li 1 hli.
• Preprocessing Techniques: Topical paper rolls with excess moisture content (>12%) mus rau 48 teev ntawm qhov kub thiab av noo tsis tu ncua tau kho thiab ionizing cua tuav (tso tawm hluav taws xob ± 7 kV) tau teeb tsa kom tshem tawm cov nqi hluav taws xob ntawm cov ntawv yob.
• Matching Slitting Parameters: Kho cov tangent ceev raws li qhov hnyav ntawm daim ntawv (g / m2), xws li:
• Hauv qab 60 g / m2: txiav ceev Tsawg dua lossis sib npaug li 150 m / min
• 60-120 g / m2: txiav ceev 80-120 m / min;
• 120 g / m2 +: txiav ceev Tsawg dua lossis sib npaug li 60 m / min

2.Upgraded Deviation Correction Systems
Rau ultra- cov ntaub ntawv nyias (piv txwv li, 0.01 mm PET zaj duab xis), ntau- theem sib txawv ntawm kev kho cov cuab yeej yuav tsum tau:

• Unwinding End: PID PID tswj algorithms rau nruab Nruab ultrasonic deviation correctors (nrhiav qhov tseeb ± 0.05 hli) los kho daim ntawv yob txoj hauj lwm nyob rau hauv lub sij hawm.
• Slitting Seem: Siv lub tshuab tso rau laser (qhov kev daws teeb meem 0.01 mm) thiab kaw -loop tawm tswv yim tswj, cov kab tangent tau khaws cia rau tib lub sijhawm ntawm daim ntawv.
• Rewinding End Txhua qhov kawg (core) yog tswj los ntawm kev siv qhov sib txawv axis nro tswj qhov system nrog kev ywj pheej torque tswj rau txhua qhov 卷芯 (core) kom tsis txhob muaj qhov kawg ntawm kev txav mus los.Practical application qhia tias lub kaw lus tuaj yeem txo qhov sib txawv ntawm 3.2% mus rau 0.05%.

1. Kaw lub voj nro tswj

Kev sib hloov ntawm kev sib hloov yog qhov tseem ceeb ntawm kev sib txawv. Nyob rau hauv ib rooj plaub, qhov tshwm sim ntawm kev sib txawv tau nce 70% thaum nro hloov ntau dua 15% ntawm qhov teeb tsa ntau. Cov kev daws teeb meem suav nrog:

• Sensor Calibration: rhiab heev ntawm qhov nro sensors raug kuaj txhua hli siv qhov hnyav (piv txwv li, 5 kg 10 kg) kom ntseeg tau tias qhov kev ua yuam kev tsawg dua lossis sib npaug ± 0.5%.
• PLC Parameter Optimization: Kho PID cov khoom siv elastic modulus (E), piv txwv li:

Cov khoom siv elastic qis (E < 1 GPa): P=0.8, I=0.2, D=0.1
(E Ntau dua lossis sib npaug rau 1 GPa): P=0.5, I=0.3, D=0.2

• Kev tswj ceev nrawm: Kev nrawm / nrawm siv S- nkhaus (kev nrawm tsawg dua lossis sib npaug li 2 m / s2) thaum lub sijhawm nrawm txhawm rau tiv thaiv kev tsis sib haum xeeb.

1. Cov khoom siv tshuaj ntsuam xyuas
Tsim kom muaj peb -tier soj ntsuam system:

• Kev txheeb xyuas txhua hnub: Kev lees paub ntawm pneumatic tivthaiv siab qhov tseem ceeb (0.4–0.6 MPa), photoelectric sensor huv huv thiab kaw thaum muaj xwm ceev hloov lub sijhawm teb (tsawg dua lossis sib npaug li 0.2 s).
• Kev saib xyuas txhua lub limtiam: ntxuav cov khoom khib nyiab, xyuas cov saw nro (ua haujlwm: 2-3 hli), lubricating guide rails (siv lithium raws roj).
• Kev Kho Ib Hlis: Hloov cov lim cua, ntsuas qhov ntsuas encoder daws teeb meem (Ntau dua lossis sib npaug ntawm 1000 pulses / kiv puag ncig), thiab kuaj kev nyab xeeb lub teeb ntaub thaiv kev ua haujlwm.

2.Txoj kev cob qhia kev ua haujlwm
Kev txhim kho cov txheej txheem kev ua haujlwm, suav nrog:

• Paper Loading: siv forklift auxiliary positioning device los xyuas kom meej qhov sib xws ntawm daim ntawv yob qhov chaw thiab cov khoom siv tsawg dua lossis sib npaug li 1 hli.
• Kev teeb tsa Parameter: Retrieves preset parameters los ntawm lub tsev qiv ntawv cov ntaub ntawv thiab txwv tsis pub hloov phau ntawv ntawm cov tsis tseem ceeb, xws li nro qhov chaw.
• Cov lus teb thaum muaj xwm txheej ceev: Tsim kev pom- thaiv cov phiaj xwm xwm txheej, suav nrog cov txheej txheem hluav taws xob, cov npe tshem tawm cov cuab yeej thiab cov cuab yeej kev nyab xeeb (xws li, tiv thaiv- hnab looj tes txiav, tsom iav kev nyab xeeb).

Xaus:
Kev daws qhov sib txawv thiab jagged hniav ntawm daim ntawv yob slitting tshuab yuav tsum muaj kev sib koom ua ke ntawm cov khoom siv kho tshuab, cov khoom siv, kev tswj thiab kev ua haujlwm. Los ntawm kev siv dynamic calibration, parameter adaptation, ntse tswj thiab standardization tswj, stability thiab ntau lawm efficiency ntawm cov cuab yeej yuav ua tau zoo dua. Cov tuam txhab lag luam yuav tsum teeb tsa kev tiv thaiv kev tiv thaiv thiab siv cov cuab yeej digital txhawm rau txhim kho cov ntaub ntawv zoo dua - tsav kev txiav txim siab thiab thaum kawg ua tiav ob qho tib si zoo thiab kev txhim kho cov txiaj ntsig.
