Nyob rau hauv niaj hnub ntim kev lag luam, thawv molding tshuab raws li cov khoom siv tseem ceeb ntawm cov thawv ntim khoom tsis siv neeg, kev ruaj ntseg ntawm nws cov kev ua tau zoo cuam tshuam rau cov khoom zoo thiab kev ua haujlwm zoo. Txawm li cas los xij, hauv cov txheej txheem tsim khoom tiag tiag, qhov saum npoo ntawm lub thawv yuav tshwm sim wrinkle, deformation thiab lwm yam teeb meem. Cov teeb meem no tsis tsuas yog degrade qhov zoo nkauj ntawm cov khoom, tab sis kuj tuaj yeem ua rau cov neeg siv khoom tsis txaus siab. Raws li kev coj ua hauv kev lag luam thiab cov txheej txheem thev naus laus zis, daim ntawv no tau txheeb xyuas cov hauv paus hauv paus ntawm cov khoom tsis ua haujlwm uas ua rau muaj kev sib tsoo hauv cov thawv ntawv thiab muab cov kev daws teeb meem rau pem hauv ntej.
I. Qhov tseem ceeb ntawm qhov teeb meem Wrinkle: kev sib cuam tshuam ntawm cov khoom siv thiab cov txheej txheem
Lub ntsiab ntawm crinkling ntawm cartons yog deformation tshwm sim los ntawm kev ntxhov siab imbalance ntawm cov khoom. Thaum lub sij hawm molding, ntawv thiab zaj duab xis (xws li OPP zaj duab xis) raug cua sov, nias, txias thiab lwm yam txheej txheem. Yog tias cov khoom siv tsis raug tswj xyuas, kev sib raug zoo ntawm cov khoom siv lub cev (xws li thermal expansion coefficient, noo noo cov ntsiab lus thiab elastic modulus) thiab cov txheej txheem tsis (xws li kub, siab thiab tshaj tawm) raug cuam tshuam, ua rau wrinkles. Piv txwv li, ib qho kev tshawb fawb ntawm cov khoom ua si ntim khoom lag luam, piv txwv li, tau qhia tias vim muaj tshuaj lom neeg cov tshuaj tiv thaiv ntawm tus cwj mem kua nplaum thiab zaj duab xis, cov thawv ntawv tuaj yeem tsim cov cobweb- zoo li cov quav thaum laminated. Tsis tas li ntawd, qhov loj ntawm corrugated cardboard tuaj yeem ua rau linear fold raws qhov kev taw qhia ntawm lub raj nplaim.
Hom Cheebtsam Failures thiab Nws Impact Mechanism
(A) Ua tsis tiav hauv Lamination System Cheebtsam
1.Kev tswj tsis zoo ntawm daim nyias nyias
Kev nro ntau dhau ntawm cov yeeb yaj kiab tuaj yeem ua rau cov khoom siv kom ntev dhau mus, tsim kom muaj kev ntxhov siab hauv cov chaw tsis muaj zog tom qab txias, xws li cov kab nrib pleb thiab cov seams, ua rau creases. Piv txwv li, nyob rau hauv ib tug tag nrho automated nyuaj lub thawv molding tshuab, misalignment ntawm unwinding cov menyuam yuav ua rau inconsistent zaj duab xis nro, ua rau wrinkles txav mus rau flabby sab thaum lub sij hawm noj mov. Cov kev daws teeb meem yuav tsum tau kho qhov nro tswj tsis tau los xyuas kom meej tias zaj duab xis elongation yog tswj kom tsawg dua 1%, thiab siv photoelectric sensors los saib xyuas qhov nro hloov tsis tu ncua.
2.Out-ntawm- tswj qhov cub kub
Qhov kub ntawm qhov cub ntau dhau ua rau lub thermal deformation ntawm zaj duab xis, tshwj xeeb tshaj yog nyob rau ntawm ntug ntug (qhov kawg ntawm zaj duab xis), qhov uas tsis sib xws thaum tshav kub kub dissipation tuaj yeem ua rau hauv zos shrinkage. Nyob rau hauv cov ntaub ntawv ntawm kev lag luam, qhov cub kub kub dhau ntawm cov khoom siv siab ntev (piv txwv li OPP zaj duab xis cov yeeb yaj kiab muaj qhov ua haujlwm zoo tshaj plaws ntawm 80 - 100 degree), ua rau cov npoo zaj duab xis curl. Lub PID kub tswj qhov system yog xav tau los txo qhov kub thiab txias hloov mus rau ± 2℃thiab ua kom qhov ntev ntawm cov kav dej txias kom ntev lub sij hawm cua sov.
3.Qhov tsis muaj zog nyob rau hauv Kev Siv Kua nplaum nplaum
Daim ntawv thov kua nplaum tsis sib xws yuav ua rau daim ntawv thiab lub zog adhesion, ua rau muaj kev ntxhov siab hauv zos. Piv txwv li, hnav ntawm Dr Copper hniav tuaj yeem ua rau lub thickness ntawm cov kua nplaum sib txawv los ntawm ntau tshaj 0.05mm, ua rau wrinkles. Kev txhim kho kev ntsuas suav nrog lub servo lub cev muaj zog-tsav kom muaj nuj nqis kua nplaum daim ntawv thov ua ke nrog lub tshuab ntsuas laser los kho cov kua nplaum txheej tuab ntawm lub sijhawm.
(B) Failures Forming Tuag Cheebtsam
1.Lub crease tuag tsis txaus Precision txaus;
Thaum qhov sib txawv ntawm qhov tob ntawm lub crease tuag ntau tshaj 0.1 mm, qhov tsis sib xws ntawm daim ntawv yuav ua rau wrinkles nyob rau hauv lub crease. Qhov loj qhov tseeb ntawm carbide crease tuag yog nce mus rau ± 0.02 hli los ntawm cov lej tswj, uas zoo heev txo cov kab sib txawv.
2.Imbalanced Pressure on Forming Dies
Kev faib tawm tsis sib xws tuaj yeem ua rau cov ntawv hauv zos overcompression, ua rau elastic rov qab deformation. Piv txwv li, thaum lub siab ntawm hydraulic system fluctuates los ntawm ntau tshaj 5%, lub thawv sidewalls yuav tshwm corrugated. Cov kev daws teeb meem suav nrog kaw- lub voj kev tawm tswv yim tswj kev siv qhov sib npaug ntawm lub siab tswj li qub thiab cov ntsuas ntsuas siab kom ntseeg tau tias qhov sib txawv siab tsawg dua 2% ntawm cov kab noj hniav tuag.
3.Failure of Die Temperature tswj
Tshaj kub kub tuag, yuav ua kom cov evaporation ntawm daim ntawv ya raws, ua rau lub zos shrinkage. Ib lub lag luam tau txo cov kev ntxhov siab thermal zoo-induced wrinkles los ntawm inserting thermocouples thiab semiconductor txias daim hlau rau hauv pwm los txo qhov kub thiab txias mus rau + / -1℃.
(C) Conveyor System Cheebtsam tsis ua haujlwm
1.Lub tshuab nqus tsev nqus tsev vacuum
Lub tshuab nqus tsev nqus tsis txaus yuav ua rau cov ntawv hauv kev thauj mus los ntawm cov txheeb ze, uas ua rau folding misalignment. Hauv ib lub cuab yeej, piv txwv li, lub tshuab nqus tsev twj tso kua mis lim tau txo qhov nqus ntawm 30%, ua rau cov kauj ruam crease raws ntug ntawm lub thawv. lim tu tsis tu ncua thiab teeb tsa lub siab hloov pauv kom tsis txhob ua haujlwm thaum lub tshuab nqus tsev qis qis dua tus nqi.
2.Txo rhiab heev ntawm Web khau raj li
Thaum lub sij hawm teb ntawm photoelectric web guiding sensors tshaj 50 milliseconds, daim ntawv yuav deviate los ntawm ntau tshaj 0.5 hli, ua rau muaj kev tsis ncaj ncees nyob rau hauv tom ntej folding. Kev txhim kho cov kev daws teeb meem suav nrog micrometer- theem web qhia siv kev sib xyaw ua ke ntawm siab- zaus teb (tsawg dua lossis sib npaug li 10 ms) CCD sensors thiab hluav taws xob actuators.
Kev nrawm nrawm ntawm Conveyor Belts
Kev hloov pauv ceev ntawm ntau dua 2% tuaj yeem ua rau daim ntawv kom ncab thiab deform. Ib lub tuam txhab siv servo motors los tsav lub servo lub cev muaj zog-tsav synchronous siv txoj siv sia siv lub tshuab ua ke nrog cov encoders tiag tiag- lub sij hawm ceev kev saib xyuas kom txhim kho kev ruaj ntseg rau ± 0.5%.
III. Systematic Solutions thiab kev tiv thaiv
(A) Txheej txheem Parameter Optimization
1.Material Preprocessing
Kev ntsuas kub thiab av noo tas li (kub 23 + 2}℃, av noo 50 + 5%) yog siv los tswj cov ntawv noo noo ntawm 5% thiab 7%, txo kev cuam tshuam nrog ib puag ncig. Rau cov txheej txheem lamination, xyuas kom tiav ziab ntawm tus number case ua ntej txheej (cov txheej txheem number case tsawg dua lossis sib npaug li 12 μm).
2.Matching Process Parameters
Tsim cov ntaub ntawv ntawm cov ntaub ntawv - txheej txheem tsis xws li:
- Rau daim ntawv nrog lub hauv paus luj ntawm 200-300 g / m2, teem lub siab ntawm 0.4-0.6 MPa
- Tswj zaj duab xis nro rau 0.5-1.2 N / mm dav
- Teem lub qhov cub kub gradient 60℃→ 80℃→ 60 degree
(B) Cov Khoom Siv Kho Kom Zoo
1.Proventive Maintenance Program

Txhua lub lim tiam: calibration ntawm photoelectric sensors thiab lubrication kis tau tus mob
Txhua hli: hloov hydraulic roj lim thiab kuaj lub siab valve kev ua haujlwm
2.Fault thaum ntxov ceeb toom system
Integrated vibration sensors, kub sensors thiab PLC tswj qhov system, cov cuab yeej tuaj yeem nres thaum vibration tshaj 5g lossis kuaj pom qhov kub tsis zoo. Ib qho kev lag luam, piv txwv li, tau siv IoT module uas siv tshuab kev kawm algorithms los kwv yees lub neej ntawm cov khoom siv thiab xa cov ntaub ntawv ua haujlwm rau huab hauv lub sijhawm.
(C) Kev cob qhia neeg ua haujlwm
Cov txheej txheem ua haujlwm tau zoo
Tsim cov ntaub ntawv SOP hais txog:
- Zaj duab xis threading txoj kev thiab nro teeb tsa cov kauj ruam
