Kev tsim cov corrugated cardboard thawv yog kev ua haujlwm siab ua haujlwm sib dhos ua haujlwm, nws feem ntau muab faib ua ob ntu: ua ntej ua corrugated cardboard, thiab tom qab ntawd siv cov duab los qhia ua cov thawv thiab luam cov qauv ntawm lawv.
Yuav ua li cas tshwj xeeb? Cov txheej txheem tau muab faib ua ob kauj ruam raws li hauv qab no:
Kauj Ruam 1: Kev tsim cov corrugated cardboard
Cov kauj ruam no tau ua tiav ntawm cov kab loj corrugated cardboard ntau lawm.
Npaj cov ntawv yob: Ob hom ntawv yob loj yog siv ntau: cov ntawv thawv ntawv (kuj nyuaj, siv rau sab hauv thiab sab nrauv ntawm lub thawv) thiab corrugated ntawv (elastic, siv rau nruab nrab wavy interlayer).
Preheating: Daim ntawv yob thawj zaug dhau los ntawm cov menyuam kub kom evaporate qee cov dej noo, ua rau daim ntawv hloov tau yooj yim dua thiab kho cov av noo kom yooj yim dua tom qab.
Squeezing nthwv dej (lub ntsiab lus tseem ceeb): Daim ntawv corrugated yog nias rau hauv cov duab nthwv dej tsis tu ncua los ntawm qhov siab -kub corrugated rau cov menyuam (xws li ob lub zog sib tsoo), thiab cov nthwv dej no hu ua "corrugations". The waves have both high and dense characteristics (such as common A-waves, B-waves, and C-waves), which determine whether the cardboard will withstand pressure and provide cushioning in the future.
Kev siv cov kua nplaum thiab kev sib txuas: Siv cov kua nplaum (feem ntau cov hmoov txhuv nplej siab) rau saum cov nthwv dej. Tom qab ntawd, nyob rau hauv siab thiab kub, lo cov ntawv sab hauv rau ntawm ib sab ntawm daim ntawv corrugated los ua ib qho - txheej corrugated cardboard. Yog tias peb xav tau peb- txheej lossis tsib txheej duab los qhia, siv cov kua nplaum rau sab nraud thiab muab cov ntawv nplaum rau ntawm ib sab.
Kev ziab thiab txias: Cov ntawv nplaum nplaum yog raug rau qhov siab - qhov kub thiab siab - qhov chaw siab, qhov uas cov nplaum tau qhuav kom huv si thiab ruaj khov, tso cai rau ob peb txheej ntawm daim ntawv kom ruaj khov ua ke. Tom qab ntawd maj mam txias thiab flatten cov duab los qhia, kom nws tiaj tus thiab muaj zog.
Txiav: Cov ntawv dav dav uas ua tsis tu ncua yog thawj zaug txiav thiab txiav tawm raws li qhov dav xav tau los ntawm kev txiav txim siv lub tshuab, thiab tom qab ntawd txiav rau hauv daim ntawv raws li qhov xav tau ntev siv lub tshuab computer- tswj kev hla kev txiav tshuab. Yog li, corrugated cardboard yog npaj txhij.
Kauj Ruam 2: Tsim thiab luam ntawv ntawm cov thawv ntawv
Raws li qhov kev txiav txim yuav tsum tau ua, ua cov ntaub ntawv tiaj tus rau hauv lub thawv ntawv kawg.
Kev luam ntawv: Feem ntau siv cov flexographic luam ntawv, uas yog ceev thiab ib puag ncig tus phooj ywg nrog dej -raws li number case. Sau cov ntawv, cov cim lag luam, thiab cov qauv ntawm cov duab los qhia. Yog hais tias nws yog ib tug tshwj xeeb exquisite xim ntim, yuav siv tau lwm yam advanced printing txoj kev.
Slotting thiab crimping:
Kab nias: Nias creases ntawm daim duab los qhia kom lub thawv folded zoo zoo.
Slotting: Txiav tawm qhov qhib ntawm lub hau thiab hauv qab ntawm lub thawv, thiab qee zaum kuj txiav cov qhov kov.
Ob kauj ruam no feem ntau tuaj yeem ua tiav ua ke los ntawm ib lub tshuab.
Tuag txiav(yog tias lub thawv ntawv tshwj xeeb): Yog tias koj xav ua cov thawv tsis xwm yeem xws li cov thawv ntim khoom, koj tuaj yeem siv lub tshuab txiav tshwj xeeb los ntaus cov duab los qhia rau hauv cov duab uas xav tau nrog pwm nrog cov hniav, ib yam li stamping.
Ntsia thawv los yog nplaum lub thawv:
Ntsia thawv: Siv lub tshuab thiab galvanized hlau los ntsia cov pob qij txha ntawm lub thawv ua ke. Qhov no yog txoj kev cai tshaj plaws thiab muaj zog.
Lub thawv nplaum: Siv lub tshuab siv cov nplaum nplaum los yog cov nplaum dawb rau kev sib txuas. Cov tsos ntawm lub thawv ua nyob rau hauv txoj kev no yog smoother thiab zoo nkauj dua, tsis muaj teeb meem ntawm rusty hlau ntsia hlau, haum rau siab - kawg ntim los yog tsis siv neeg ntim kab.
Tom qab ua tiav cov kauj ruam no, cov duab los qhia ua "lub thawv ntim" uas tuaj yeem muab tais, ua kom yooj yim rau kev thauj mus los thiab khaws cia.
Ntim thiab khaws cia: Cov khoom ua ntej- ua cov thawv ntawv yog flattened thiab stacked, bundled rau hauv tej pob khoom nyob rau hauv ib tug tej yam kom muaj nuj nqis, sau ntawv, thiab npaj txhij rau cia thiab xa khoom.
Yog li, cov txheej txheem yooj yim yog raws li hauv qab no:
Daim ntawv yob → Preheating → Wave pressing → Adhesive bonding → Drying and cooling → Cutting to cardboard → Printing → Slotting, line pressing/tilling-txiav → Nail box or adhesive box (ua rau hauv lub thawv ntawv) → Ntim thiab cia
Ntau lub ntsiab lus tseem ceeb yuav tsum tau hais txog:
Daim ntawv zoo: Lub thickness thiab lub zog ntawm cov duab los qhia thiab cov ntawv corrugated ncaj qha txiav txim siab seb lub thawv ntawv yog qhov ruaj khov lossis tsis yog.
Wave xaiv: Ib nthwv dej muaj qhov tsis zoo; B ridges yog qhov tiaj tus thiab muaj kev kub siab ua haujlwm; C muaj kev ua haujlwm zoo; E/F tav yog zoo heev thiab siv rau ntim me me thiab siab - cov khoom zoo.
Adhesive: Cov mis thiab ziab kub tswj cov hmoov txhuv nplej siab yog qhov tseem ceeb.
Automation: Niaj hnub no, cov kab ntau lawm feem ntau yog khoos phis tawj - tswj qhov loj, qhov kub thiab ceev, uas ua haujlwm tau zoo dua thiab meej.
Hauv cov ntsiab lus, qhov no yog tag nrho cov txheej txheem ntawm corrugated cardboard thawv los ntawm raw khoom yob mus rau qhov kawg ntim.
