Nrog lub ntiaj teb no cov yas txwv tsis pub muaj zog thiab cov neeg siv khoom ib puag ncig kev paub txog kev nce siab, kraft ntawv hnab tau hloov los ntawm "zoo- rau- muaj" kev xaiv mus rau qhov tsim nyog hauv khw muag khoom, kev pabcuam zaub mov, thiab ntim khoom plig. Txawm hais tias nws yog lub khw kas fes ntawm lub ces kaum lossis lub khw muag khoom loj, cov hnab ntawv kraft tau xyaum txhua qhov chaw. Hauv qab scenes, lubSemi Tsis Siv Neeg Kraft Daim Ntawv Hnab Tshuabua lub luag haujlwm tseem ceeb rau cov khoom me me thiab nruab nrab - ntim ntim, ua lub luag haujlwm tseem ceeb tshaj li cov neeg feem coob paub.
Yog tias koj nyuam qhuav pib hauv kev lag luam, tej zaum koj yuav xav tsis thoob: yuav ua li cas raws nraim li lub semi- tsis siv neeg lub tshuab tig lub tiaj, tsis zoo ntawm daim ntawv kraft rau hauv cov txheej txheem ua tiav, lub hnab ntawv ruaj khov? Cov kauj ruam twg yog tag nrho cov kab ntau lawm tiag tiag? Kab lus no taug kev los ntawm cov txheej txheem txij li pib mus rau qhov kawg, rhuav tshem txhua theem kom tsis muaj dab tsi poob hauv kev txhais lus.
1. Raw Material Preparation - Cov ntawv zoo ua cov hnab zoo
Txhua yam pib nrog xaiv cov ntawv.
Qhov zoo ntawm lub hnab ntawv kraft nyob ntawm nws cov khoom siv raw ntau dua li lwm yam. Hauv kev tsim khoom, kraft ntawv feem ntau tuaj nyob rau hauv ob hom: ntuj (xim av) thiab bleached (dawb). Cov ntawv hnyav feem ntau yog li ntawm 70 g / m² txog 250 g / m². Cov ntawv hnyav dua txhais tau tias lub hnab tuab dua thiab muaj zog dua. Qhov hnyav ntawm 120-150 g / m² yog qhov qub rau cov hnab yuav khoom. Hnyav- lub luag haujlwm ntim khoom lag luam yuav xav tau 200 g / m² lossis ntau dua.
Cov khoom siv raw feem ntau tuaj txog ntawm lub Hoobkas hauv cov jumbo yob loj. Thawj kauj ruam yog slitting. Cov neeg ua haujlwm siv lub slitting rewinder los txiav qhov dav jumbo yob rau hauv cov yob yob uas phim lub hnab lub hom phiaj dav. Cov kauj ruam no yuav zoo li yooj yim, tab sis qhov loj me yog qhov tseem ceeb. Txawm tias qhov sib txawv ntawm 1 hli hauv qhov dav tuaj yeem ua rau muaj teeb meem hauv folding thiab kev sib txuas. Cov neeg ua haujlwm yuav tsum ua tib zoo teeb tsa cov hniav sib nrug thiab cov ntawv nruj. Qhov no ua kom cov txiav kom huv si thiab du, tsis muaj frayed npoo los yog wrinkles.
Cov lus qhia ceev: Thaum khaws cov ntawv kraft yob, ua tib zoo saib xyuas qhov ntsuas kub thiab av noo. Kraft daim ntawv absorbs noo noo los ntawm huab cua, uas ua rau deformation. Factory humidity yuav tsum tau khaws cia ntawm 50% thiab 65%.
2. Printing - Tig lub hnab rau hauv lub hnab ntim khoom
Tsis yog txhua lub hnab ntawv kraft xav tau luam ntawv, tab sis hauv cov ntawv thov kev lag luam, ntau dua 90% ntawm kev txiav txim suav nrog cov logos, hom xim, lossis cov ntaub ntawv khoom. Lub sijhawm luam ntawv feem ntau ua tiav ua ntej lub hnab tsim.
Hauv ib nrab - tsis siv neeg ntau lawm kab, flexographic luam ntawv yog txoj kev siv dav tshaj plaws. Nws ua haujlwm los ntawm kev txav eco- dej tus phooj ywg-raws li tus cwj mem los ntawm cov ntawv muag muag (zoo ib yam li letterpress) ncaj nraim rau ntawm daim ntawv. Flexo luam ntawv muaj ob peb lub ntsiab lus zoo: kev kub ceev, tus nqi qis, ceev kom qhuav, thiab dej-raws li inks uas ua tau raws li cov zaub mov- qib ntim cov cai ib puag ncig. Rau cov neeg siv khoom uas xav tau cov xim sib xws - xws li hom xim xim - offset lossis gravure luam ntawv yuav xav tau hloov.
Tom qab luam ntawv, daim ntawv mus rau hauv qhov kub - cua tshuab ziab khaub ncaws los yog lub tshuab ziab khaub ncaws infrared. Qhov no kho tus number case sai sai thiab tsis txhob smudging los yog kos npe thaum cov nplooj ntawv yog stacked.
Qhov teeb meem: Yog tias koj pom tias kev sau npe tsis raug thaum luam ntawv, thawj zaug xyuas seb qhov web nro puas sib npaug, tom qab ntawd xyuas kom meej tias daim ntawv luam ntawv tsis tau xoob. Ob yam no suav nrog rau feem coob ntawm cov teeb meem kev sau npe.
3. Lub Hnab Lub Cev Tsim - Cov kauj ruam tseem ceeb ntawm lub tiaj tus mus rau peb-Dimensional
Qhov no yog theem tseem ceeb tshaj plaws ntawm tag nrho cov txheej txheem. Qhov no yog qhov uas Semi Automatic Kraft Paper Bag Tshuab ua nws txoj haujlwm tseem ceeb.
Cias muab, lub hnab lub cev tsim siv ib daim ntawv tiaj tus thiab yob nws mus rau hauv lub raj - lub cev lub cev. Nov yog qhov nws ua haujlwm li cas:
3.1 Creasing thiab Sab Folding
Cov ntawv luam tawm (lossis tsis tau luam tawm) ua ntej dhau los ntawm qhov chaw nres tsheb creasing. Txoj hauj lwm ntawm creasing yog nias kom meej fold kab ua ntej. Qhov no ua kom cov kab folding raws nraim. Rau cov square-cov hnab hauv qab, cov creases rau sab gussets yuav tsum tau nias rau hauv. Cov no yog cov foldable sab uas cia lub hnab qhib thiab muab nws peb - qhov loj me thiab chav nyob sab hauv.
3.2 Tube txoj kev
Daim ntawv lub vev xaib pub los ntawm kev qhia cov menyuam mus rau yav dhau los - ib lub conical lossis wedge- zoo li cov lus qhia hlau.
Raws li daim ntawv qhwv ib ncig ntawm lub qub, ob sab ntug sib tshooj los ntawm tus nqi teev. Qhov no feem ntau yog 15 mus rau 25 mm. Ib lub nplaum nplaum muab cov nplaum rau ntawm qhov sib tshooj sib npaug. Tom qab ntawd lub siab rollers nias lub seam ua ke. Qhov no ua rau lub raj ntawv txuas ntxiv.
Ntawm ib nrab- cov cuab yeej siv tsis siv neeg, cov kauj ruam no feem ntau yuav tsum muaj kev pabcuam phau ntawv rau kev pib noj cov ntawv thiab kev sib tw. TOperators pub rau pem hauv ntej ntug rau pem hauv ntej ntug thiab lub tshuab yuav siv sij hawm tshaj kev sib txuas, compression thiab xa. Qhov ntawd yog qhov "semi- tsis siv neeg" daim ntawv lo los rau hauv - tshuab ua cov txheej txheem tseem ceeb, tab sis tseem cia siab rau tib neeg cov tswv yim rau kev pub noj thawj zaug thiab kev taw qhia.
3.2 Txiav rau Length
Thaum ua lub raj txuas txuas ntxiv, nws yuav tsum tau txiav rau hauv nyias lub hnab ntev. Semi- cov tshuab tsis siv neeg feem ntau yog siv cov riam txiav los yog pneumatically tsav guillotine txiav. Txhua qhov txiav ua rau ib lub hnab lub cev. Txiav qhov tseeb ncaj qha cuam tshuam rau qhov siab siab ntawm lub hnab tiav, uas feem ntau khaws cia hauv ± 1 hli.
Lus Cim: Cov hniav txiav yuav tsum tau muab cov ntse ntse los yog hloov. Cov nplooj npub ua cov npoo ntxhib, thiab qhov ntawd ua rau lub hnab tiav zoo li cas.
4. Hauv qab folding thiab sealing - Dab tsi txiav txim siab npaum li cas lub hnab nqa tau
Lub hnab lub cev yog tsim tab sis hauv qab yog tseem qhib - txhua yam tso rau hauv yuav poob los ntawm. Hauv qab folding thiab sealing yog li ib kauj ruam tseem ceeb.
