Thaum nws los txog rau qhov tsis muaj corrugated cardboard, ntau tus neeg yuav xav txog corrugated cardboard. Qhov tseeb, qhov tshwm sim no tsis zoo ib yam li inverted. Nws raug nquahu kom tshawb xyuas los ntawm ntau yam xws li cov khoom siv raw, ib lub pobzeb tshuab, flyovers, pasting machines, conveyor siv, siab rollers, thiab sab nraub qaum ntawm cov nplais kab los soj ntsuam cov laj thawj thiab daws lawv.
(1) Cov khoom siv raw
Cov ntawv corrugated siv yuav tsum ua raws li cov qauv hauv tebchaws. Piv txwv li, rau 105 grams ntawm corrugated ntawv, lub hauv paus ntawv tsim yuav tsum tau raws li B-theem teb chaws tus qauv. Lub nplhaib siab ntawm C-theem ntawv tsis txaus, thiab nws yooj yim ua rau corrugation vau.
Kev tswj xyuas kev ua haujlwm zoo ntawm txhua lub thawv ntim khoom yuav tsum nyob hauv qhov chaw. Lub tuam txhab thawj zaug teeb tsa tus txheej txheem koom nrog, thiab tom qab ntawd xav kom tus neeg muag khoom ua nws raws li tus qauv.
(2) Ib leeg pobzeb tshuab
1) Kub.
Puas yog qhov kub ntawm cov menyuam corrugating txaus? Thaum qhov kub ntawm lub corrugated pas nrig tsis txaus, qhov siab ntawm corrugation ua tsis txaus. Feem ntau, lub tuam txhab tswj hwm zoo yuav xa ib tus neeg los xyuas qhov ntsuas kub ntawm tag nrho cov kab sib dhos (nws pom zoo kom tus neeg saib xyuas lub boiler ua haujlwm no). Thaum pom qhov teeb meem ntawm qhov kub thiab txias, tus thawj saib xyuas ntawm lub luag haujlwm thiab tus thawj coj ntawm lub tshuab raug ceeb toom rau lub sijhawm, cov neeg kho tshuab tau ceeb toom kom daws tau nws, thiab txhua lub tog raj kheej preheating raug tshuaj xyuas thiab kho txhua lub hlis.
2) Cov av nyob rau saum npoo ntawm cov menyuam corrugated.
Ua ntej pib ua haujlwm txhua hnub, cov menyuam corrugated yog preheated thiab txhuam nrog lub teeb cav roj los ntxuav cov slag thiab khib nyiab ntawm cov menyuam corrugated.
3) Kev hloov kho ntawm qhov sib txawv ntawm cov yob yog qhov tseem ceeb heev hauv kev tsim khoom.
Qhov sib txawv ntawm cov gluing cov menyuam thiab cov corrugating cov menyuam feem ntau yog thaum cov menyuam corrugating preheated rau 30 feeb kom nthuav dav ntawm cov menyuam corrugating. Lub thickness ntawm ib daim ntawv nrog qhov hnyav tshaj plaws hauv lub tuam txhab yog siv los ua qhov sib txawv. Nws yuav tsum tau kuaj xyuas txhua hnub ua ntej pib lub tshuab.
Qhov sib txawv ntawm cov menyuam corrugating thiab lub siab rau cov menyuam feem ntau txiav txim siab raws li qhov xwm txheej tsim khoom, thiab yuav tsum tau ua kom zoo.
Qhov sib txawv ntawm lub corrugating rau sab sauv thiab qis corrugating roller yog qhov tseem ceeb heev. Yog tias nws tsis raug kho kom raug, cov duab ntawm cov corrugation tsim yuav tsis zoo, uas feem ntau yuav ua rau tsis txaus thickness.
4) Lub degree ntawm hnav ntawm corrugated roller.
Tshawb xyuas cov xwm txheej ntawm cov corrugated yob txhua lub sijhawm, seb nws puas tsim nyog los hloov nws. Nws raug nquahu kom siv tungsten carbide corrugated cov menyuam, vim nws qhov hnyav hnyav tuaj yeem txo cov nqi tsim khoom. Nyob rau hauv cov ntaub ntawv ntawm kev ua haujlwm ruaj khov, nws kwv yees tias tus nqi yuav rov qab los ntawm 6-8 lub hlis.
(3) Hla daim ntawv flyover
Tsis txhob sib sau ntau dhau ib daim ntawv pobzeb ntawm lub flyover. Yog tias qhov nro loj dhau lawm, daim ntawv ib leeg-pob zeb yuav raug hnav thiab cov duab los qhia yuav tsis tuab txaus. Nws raug nquahu kom nruab ib lub khoos phis tawj tswj kev tsim khoom, uas tuaj yeem tiv thaiv cov xwm txheej zoo li no los ntawm kev tshwm sim, tab sis tam sim no ntau lub tuam txhab tsim khoom hauv tsev muaj lawv, tab sis lawv yuav tsis siv, uas yog pov tseg.
Thaum xaiv ib lub chaw tsim khoom flyover, yuav tsum tau ua tib zoo xav kom tsis txhob muaj kev cuam tshuam los ntawm huab cua nkag ntawm flyover. Yog hais tias huab cua nkag ntawm lub flyover loj dhau lawm, nws yooj yim heev ua rau lub corrugation tawg. Ua tib zoo saib xyuas qhov kev sib hloov ntawm txhua axis, thiab xyuas qhov sib luag ntawm txhua lub axis nquag thiab ua tib zoo saib xyuas txhua lub sijhawm.
(4) Muab tshuaj txhuam tshuab
1) Lub tshuab nias rau ntawm cov menyuam muab tshuaj yog qhov tsawg dhau, thiab qhov sib txawv ntawm cov xovxwm yuav tsum tau kho, feem ntau yog 2-3 hli.
2) Ua tib zoo saib cov radial thiab axial runout ntawm lub siab cov menyuam, thiab nws tsis tuaj yeem ua elliptical.
3) Muaj ntau yam kev paub hauv kev xaiv qhov kov bar. Tam sim no ntau thiab ntau lub chaw tsim khoom tau xaiv los siv kev sib cuag nrog cov pas nrig li caij tsheb kauj vab (xovxwm rollers). Qhov no yog qhov kev hloov pauv loj, tab sis tseem muaj ntau qhov xwm txheej uas cov neeg ua haujlwm yuav tsum tau kho lub siab.
4) Tus nqi ntawm cov tshuaj yuav tsum tsis txhob loj heev, thiaj li tsis ua rau deformation ntawm Lengfeng. Nws tsis yog tias qhov loj dua cov kua nplaum, qhov zoo dua qhov haum, peb yuav tsum tau them sai sai rau cov kua nplaum thiab cov txheej txheem ntau lawm.
(5) Canvas siv
Txoj siv tawv canvas yuav tsum tau ntxuav tsis tu ncua ib hnub ib zaug, thiab txoj siv ntaub ntaub yuav tsum tau ntxuav txhua lub lim tiam. Feem ntau, txoj siv tawv canvas yog tsau rau hauv dej rau ib lub sij hawm, thiab tom qab nws softened, nws yog ntxuav nrog ib tug hlau txhuam. Tsis txhob sim txuag lub sijhawm ntawm lub sijhawm thiab ua rau lub sijhawm poob ntau ntxiv thaum cov khoom sib xyaw nce mus txog ib theem.
Txhawm rau tsim cov khoom lag luam zoo, cov ntaub qhwv ntsej muag yuav tsum muaj huab cua zoo permeability. Tom qab ncav cuag ib lub sijhawm, nws yuav tsum tau hloov. Tsis txhob ua rau cov duab los qhia rau warped vim kev txuag nqi ib ntus, thiab qhov nce ntau tshaj qhov poob.
(6) Siab cov menyuam
1) Yuav tsum siv tus lej tsim nyog ntawm lub siab chais. Nyob rau hauv lub caij sib txawv, tus naj npawb ntawm lub siab rollers siv yog sib txawv, thiab yuav tsum tau kho raws sij hawm raws li qhov tseeb.
2) Lub radial thiab axial cov lus qhia ntawm txhua lub siab cov menyuam yuav tsum tau tswj nyob rau hauv 2 filaments, txwv tsis pub lub siab cov menyuam nrog ib tug oval puab yuav overwhelm lub corrugations, ua rau tsis txaus thickness.
3) Qhov sib txawv ntawm lub siab rau cov menyuam thiab cov phaj kub yuav tsum tau hloov kho, tawm hauv chav rau kev kho kom zoo, uas tuaj yeem hloov kho raws li cov duab (qhov siab) ntawm corrugation.
4) Nws raug nquahu tias cov tuam txhab tsim khoom siv cov ntawv xovxwm kub es tsis txhob siv lub siab chais, ntawm chav kawm, qhov chaw ua haujlwm ntawm cov neeg ua haujlwm yuav tsum mus txog qib ntawm kev siv cov khoom siv automation.
(7) Sab nraub qaum ntawm cov nplais kab
Kev nkag thiab tawm ntawm rab riam hlais yuav tsum siv lub hnub ci tsim nyog. Feem ntau, nws yog 55 degrees rau 60 degrees nrog rau Shore hardness tester kom tsis txhob crushing cov duab los qhia.
