Yog tias koj tau pom ib lub khob pov tseg tawm ntawm ib daim ntawv hauv tsawg dua ob vib nas this, koj tau saib lub khob khob tsis siv neeg ua haujlwm. Nws zoo li yooj yim heev. Tab sis qhov ntawd tsis yog li ntawd. Muaj rau theem sib txuas zoo tom qab qhov kev txav mus los no. Txhua qhov yog raws li qhov me me ntawm qhov yuam kev, ntsuas hauv millimeters.
Ib kauj ruam dhau los, tsab xov xwm mus dhau tag nrho cov txheej txheem tsim khoom. Nws tsis siv cov khoom lag luam lossis cov koom haum sib txuas. Nws tsuas yog qhia qhov tseeb mechanics ntawm yuav ua li cas ib daim ntawv tiaj tus yob ua lub khob tiav.
Kauj Ruam 1: Daim ntawv pub mis thiab Unwinding
Nws tag nrho pib nrog yob cov zaub mov- ntawv qib. Feem ntau 180-350 GSM. Nws nyob ntawm seb koj tab tom ua ib qho - khob kas fes phab ntsa lossis ob - cov thawv ntim cov kua zaub.
Lub scroll yog nyob rau hauv hydraulic unwinding sawv ntsug. Lub kaw lus nruj tswj kom cov ntawv nruj thaum nws nkag mus rau hauv lub tshuab. Yog tias daim ntawv xoob dhau, nws wrinkles. Yog nws nruj heev, nws yuav tsim kua muag. Cov ntawv tsis sib xws yog qhov feem ntau ua rau cov ntawv khob ntim khoom tsis xws luag, raws li FAO's Packaging Sustainability Report 2022. Nws ua rau muaj li 30% ntawm cov mugs raug muab tso tseg.
Daim ntawv ces hla dhau ib qho chaw preheating. Kub daim ntawv rau ib ncig ntawm 80-120C ntawm ib tug menyuam. Qhov no ua rau cov fibers mos txaus khoov yam tsis muaj kev tawg. Yog tias koj hla cov kauj ruam no, lub khob phab ntsa yuav tawg thaum molding. Txawm yog tus tshaj plawsautomatic ntawv khob ua tshuabtso siab rau qhov tseem ceeb preheating kom ntseeg tau tias cov khoom siv tau yooj yim.
Theem 2: Khob phab ntsa tsim (Knurling thiab Curling)
Qhov no yog qhov uas daim ntawv tiaj tus pib ua cov raj.
Lub tshuab nias ib txoj hlua ntev rau hauv daim ntawv nrog rau cov menyuam. Tom qab ntawd khoov daim ntawv rau hauv ib lub voj voog nrog lub rhuab curling board. Ntug sib tshooj txog 3-5 mm. Overlapping sab seam ntawm lub khob.
Ib daim ntawv tshaj tawm kev tshaj tawm los ntawm International Trade Center (ITC) hais tias cov txheej txheem tsim kom muaj kev tswj xyuas qhov kub thiab txias kom raug rau +/ -2 degree. Cov kev hloov me me ntawm qhov kub thiab txias tuaj yeem ua rau daim ntawv curl tsis zoo lossis kub hnyiab.
Lub sijhawm no, koj muaj lub raj xa ntawv nrog qhib sab saum toj thiab hauv qab. Tsis yog ib khob.
Theem 3: Sab Sealing (Ultrasonic lossis Cua Kub)
Cov npoo sib tshooj ntawm cov ntawv raj yuav tsum tau koom nrog rau hauv ib qho chaw ruaj khov. Feem ntau cov tshuab tshiab siv ultrasonic vuam siv cov kua nplaum.
Lub tshuab hluav taws xob ultrasonic kis tau siab - zaus vibrations, feem ntau 20-40 kHz, los ntawm cov neeg hais lus thiab cov pob zeb. Kev sib txhuam ua kom sov. Qhov cua sov no txaus los yaj cov ntawv fibers ntawm cov seams. Kev ntxhov siab ua rau lawv ua ke. Cov txheej txheem siv sijhawm tsawg dua 0.3 vib nas this.
Lub Koom Haum Ntiaj Teb Kev Txawj Ntse tau qhia ntau dua 340 daim ntawv thov rau ultrasonic foob patents rau khob tshuab tau thov ntawm 2018 thiab 2024. Qhov no tsis yog vim lub tswv yim tshiab. Qhov no yog vim nws nyuaj rau ua ib lub foob zoo. Cov ntsaws ruaj ruaj yuav tsum muaj zog txaus los tuav cov kua, ntxuav kom txaus noj, thiab ceev txaus kom muaj txiaj ntsig zoo.
Qee lub tshuab qub lossis pheej yig dua tseem siv cua kub sealing. Nws ua haujlwm, tab sis nws qeeb qeeb thiab muaj cov seams tuab. Lub koom haum UN Industrial Development Organization (UNIDO), nyob rau hauv nws 2023 SME Equipment Guide, tau sau tseg tias ultrasonic sealing yog tus qauv kev lag luam rau zaub mov- qib khob ntau lawm. High -zooautomatic ntawv khob ua tshuabyuav luag ib txwm feature ultrasonic sealing ua ib feem tseem ceeb ntawm theem no.
Theem 4: Hauv qab sealing thiab sib sau
Tam sim no lub tshuab yuav tsum tau kaw hauv qab ntawm cov yeeb nkab. Nws tseem yuav tsum tau ua kom zoo li tus nkhaus hauv qab ntawm lub khob ntawv.
Cov txheej txheem tau muab faib ua ob theem me me:
4 ib a. Hauv qab Punching-Lub voj voog tuag hla hauv qab ntawm daim ntawv. Lub voos xwmfab no ua rau hauv qab ntawm lub khob.
4b ib. Hauv qab Folding thiab foob -Push lub nplhaib txiav rau hauv cov pwm nkhaus. Cov npoo folds sab hauv mus rau hauv ib tug series ntawm pleats. Qhov no feem ntau yog 4 mus rau 6 pleats, nyob ntawm qhov loj ntawm lub khob. Tom qab ntawd cov pleats raug kaw rau ntawm phab ntsa ntawm lub khob nrog lub tshuab ultrasound lossis cua kub.
Qhov no yog lub feem ntau mechanically complex theem. Cov pleats yuav tsum du. Yog tias cov pleats tsis sib xws, lub khob tsis tuaj yeem muab tso rau ntawm qhov chaw. Nws kuj tso rau hauv siab. Lub koom haum Ntim Machinery Manufacturers (PMMI) tau hais tias qhov tsis ua haujlwm ntawm lub foob hauv qab ua rau kwv yees li 25% ntawm kev tsis lees paub zoo hauv khob ntau lawm.
Theem 5: Khob Knockout thiab Hloov
Thaum lub hauv qab yog kaw, lub khob tiav tseem nyob hauv pwm. Tus kais tus pin thawb lub khob tawm ntawm txoj kev tuag. Lub tshuab nqus tsev hloov pauv lossis lub caj npab robotic ces khaws nws thiab txav mus rau qhov tso zis conveyor.
Ntawm - cov kab ceev uas khiav ntau dua 150 khob ib feeb, kev sib kis yuav tsum siv li 50 milliseconds. Ib qho kev ncua yuav ua rau muaj kev tsis sib haum xeeb thiab ua rau txoj kab qeeb.
Raws li OECD's 2023 kev tsim tus nqi Performance index, tus qauv tsim ntawm kev hloov tshuab tsim yog qhov sib txawv ntawm nruab nrab - thiab siab - kawg qauv. Cov tshuab pheej yig dua siv cov cuab yeej robotic yooj yim. Cov kab siab heev siv servo- tsav lub tshuab nqus tsev nrog lub sijhawm tiag tiag - qhov chaw taug qab. Qhov kev hloov pauv qhov tseeb no yog qhov cais cov qauv ntsuas los ntawm tus nqi themautomatic ntawv khob ua tshuabnyob rau hauv cov nqe lus ntawm kev ceev thiab kev cia siab.
Kauj Ruam 6: Stacking, suav, thiab ntim
Qhov kawg theem tsis yog ib feem ntawm lub khob nws tus kheej. Tab sis nws tseem yog ib feem tseem ceeb ntawm lub tshuab tso zis.
Cov khob tshuaj yej tau muab tso rau hauv pawg ntawm 25 lossis 50. Cov no yog cov qauv suav. Ib qho optical suav sensor xyuas tus lej. Yog tias suav tsis raug, pawg yuav raug tso tseg.
Tom qab ntawd qhwv cov pawg hauv cov yas nyias los yog muab tso rau hauv ib lub thawv ntawv. Qee cov kab ntau lawm muaj automatedlabeling systems lossis barcode tshuab luam ntawv los taug qab cov khoom muag.
Hauv nws cov lus qhia txog kev ua raws li cov tshuab ua raws, European Committee for Standardization (CEN) hais tias cov suav thiab ntim cov theem yuav tsum ua kom tau raws li qhov tseeb ntawm cov tshuab muag hauv EU. Qhov no feem ntau yog ± 1 khob ib pawg ntawm 50.
Muab Tag Nrho Ua Ke: Cycle Time Breakdown
| Theem | Lub Sijhawm Hom (ib khob) |
|---|---|
| Ntawv pub & preheating | 0.4-0.6 sec |
| Phab ntsa tsim (knurling + curling) | 0.3-0.5 sec |
| Sab sealing (ultrasonic) | 0.2–0.3 sec |
| Hauv qab txiav | 0.1–0.2 sec |
| Hauv qab folding & sealing | 0.4-0.6 sec |
| Knockout & hloov | 0.1–0.2 sec |
| Stacking & suav | 0.3-0.5 sec |
| Tag nrho lub sijhawm voj voog | 1.8–3.0 sec |
Txhua lub khob siv sijhawm 2 vib nas this, lossis 30 khob ib feeb. Ob chav chamber yog 60 khob ib feeb. Plaub chav, 120 khob ib feeb. Tias yog vim li cas lub peev xwm yog qhov tseem ceeb hauv kev siv tshuab nqi. Thaum kawg, tag nrho lub sij hawm voj voog txiav txim siab qhov tso zis ntawm ib qho twgautomatic ntawv khob ua tshuab.
Vim li cas qhov txheej txheem no tseem ceeb rau cov neeg yuav khoom
Kev nkag siab txog cov txheej txheem tsim khoom tuaj yeem pab koj nkag siab qhov koj tau them tiag tiag. Cov tshuab pheej yig dua tuaj yeem hla cov kauj ruam ua ntej los yog siv cov huab cua yooj yim tsis siv ultrasound. Nws txuag nyiaj hauv thawj qhov chaw. Tab sis nws tsim ntau lub khob tsis lees paub, ntau lub sijhawm poob, thiab khob uas tsis ua haujlwm thaum tib neeg siv lawv.
Raws li Tuam Tshoj Ntim Machinery Industry Products Market Research Report 2023 los ntawm Lub Ntiaj Teb Ntim Machinery Industry Association, tag nrho ultrasonic sealing thiab servo-tsav hloov tshuab muaj cov tshuab tsis ua haujlwm qis dua 2%. Qhov nruab nrab tsis ua hauj lwm tus nqi rau theem pib ib nrab- cov kab ntau lawm yog 8 - 12%. Hauv ib xyoos ntawm kev tsim khoom, qhov sib txawv ntawm cov khib nyiab ib leeg tuaj yeem tshaj tus nqi sib txawv ntawm ob lub tshuab.
Tsis txhob cia li sib piv cov ntawv nplaum cov nqi koj kos tawm cov ntawv tsis siv neeg lub khob molding tshuab. Sib piv cov txheej txheem. Cov tshuab ua haujlwm ntawm txhua theem kom raug yuav raug nqi ntau dua hnub no. Tab sis nws yuav cawm koj ntau tag kis.
