4.2 Folding Belts thiab Guide
Ntawm cov cav tov uas khiav ntawm kev kub ceev, nyob ruaj ruaj folding plows yuav tsis muaj peev xwm tswj tau lub folded vaj huam sib luag tom qab nws tau dhau qhov folding cheeb tsam.folding sivkhiav ib sab ntawm txoj kev dawb paug thiab tuav cov folded panels nyob rau hauv lawv txoj hauj lwm tsim, siv lub teeb nruam siab kom txog thaum lub vaj huam sib luag mus txog qhov chaw gluing thiab nias. Qhov no tiv thaiv lub caij nplooj ntoos hlav-rov qab los ntawm rov qhib lub quav ua ntej cov nplaum tuaj yeem teeb tsa.
4.3 Rotary thiab Reciprocating Fold Mechanisms
Rau cov hom quav tshwj xeeb - xws li hauv qab tuck- nyob rau hauv nrov plig plawg ntawm cereal-style carton los yog plua plav nrov plig plawg ntawm lub hau - rotary folders los yog pneumatically actuated reciprocating hniav ua rau ceev ceev, quab yuam quav uas tsis tuaj yeem ua tiav los ntawm gradual plow.
Cov txheej txheem no tau teem sijhawm raws nraim mus rau qhov chaw seem hauv lub voj voog tshuab. Lawv feem ntau siv lub cam-tsav los yog servo-tsav actuator. Qhov no actuator ua rau ntawm ib tug txheej encoder suav. Qhov kev suav ntawd suav nrog qhov khoob ntawm sab xub ntiag lossis sab nraub qaum dhau los ntawm kev siv sensor.
5. Adhesive Application: Tsim daim ntawv cog lus
Ntawm qhov tseeb ntawm qhov sib tw folding - tom qab cov nplaum nplaum tau muab tais rau nws lub kaum ntse ntse tab sis ua ntej lub vaj huam sib luag raug nias tawm tsam nws - nplaum yog siv rau cov nplaum nplaum nplaum.
Kub-Melt vs. Cold Glue
Kub- nplaum nplaumyog qhov kev xaiv tseem ceeb nyob rau hauv siab - ceev carton ua. Siv raws li cov hlaws molten ntawm qhov kub thiab txias feem ntau ntawm 140℃thiab 180 degree, nws teem sai sai thaum nws txias thiab muab ib qho ntsuab tam sim ntawd - lub zog daim ntawv cog lus uas tso cai rau lub tshuab nias thiab tso cov seam nyob rau hauv ib lub voj voog tshuab. Kub- melted yog txhim khu kev qha, dav siv tau nrog cov ntaub ntawv substrates, thiab yuav tsum tsis muaj sij hawm ziab los yog UV curing.
Txias (dej{0}}raws li) nplaumyog siv nyob rau hauv cov ntawv thov uas kub rhiab heev yog ib qho kev txhawj xeeb - piv txwv li, nyob rau hauv cartons nrog tshav kub- rhiab laminate coatings los yog qhov twg cov nplaum yuav tsum nyob twj ywm repositionable rau ib lub sij hawm tom qab daim ntawv thov. Cov kua nplaum txias yuav tsum tau nyob ntev dua los yog qis qis kom qhuav, uas txwv kev ua haujlwm ceev.
Txoj kev thov
Feem ntau cov thawv thawv ua tshuab siv cov nplaum los ntawm anozzle system- ib los yog ntau tshaj rhuab dispensing nozzles uas tso ib tug meej hlaws ntim ntawm ib lub sij hawm nyob rau hauv lub voj voog. Lub nozzle qhib thiab kaw nyob rau hauv teb rau lub teeb liab los ntawm lub tshuab PLC, tshwm sim los ntawm ib tug dawb paug - txoj hauj lwm encoder. Bead dav, ntev, thiab txoj hauj lwm yog tswj los ntawm kev kho nozzle qhib lub sij hawm, tshuab ceev, thiab nozzle lateral txoj hauj lwm.
Kev siv cov nplaum nplaum yog qhov tseem ceeb. Ib tug hlaws uas luv dhau tawm ib feem ntawm lub seam un-bonded; wide thiab nplaum yuav nyem tawm thiab paug lub tshuab los yog cov khoom tiv tauj nto. Ntawm cov kab ntim khoom kim heev, lub zeem muag saib xyuas txhua cov hlaws nplaum tom qab thov thiab tsis lees txais qhov khoob qhov twg tus qauv ntog sab nraud.
6. Nias thiab Seam Tsim
Tom qab cov nplaum tau thov thiab cov kua nplaum nplaum tau coj mus rau hauv kev sib cuag nrog nws lub vaj huam sib luag, lub seam yuav tsum tau tuav nyob rau hauv siab rau lub sij hawm nyob rau hauv lub sij hawm kom tso cai rau daim ntawv cog lus kom muaj zog txaus rau downstream tuav.
Nias Belt Systems
Feem ntau tas mus li -khiav lub thawv ua tshuab sivnias siv- ib khub ntawm qhov sib npaug ntawm cov conveyor siv khiav ntawm lub tshuab ceev, ib qho saum toj thiab ib qho hauv qab lub thawv ntim. Qhov sib txawv ntawm txoj siv sia yog teem rau qhov siab ntawm lub thawv tiav, siv lub siab nruam mus rau qhov chaw seam thoob plaws hauv seem nyob. Qhov ntev ntawm txoj siv xovxwm txiav txim siab tag nrho lub sijhawm nyob ntawm lub tshuab ceev.
Kev sib raug zoo ntawm lub tshuab ceev, nias txoj siv ntev, thiab lub sij hawm nyob hauv yog ib qho kev txwv tsim. Lub tshuab ua haujlwm ntawm 200 cartons ib feeb nrog 1.5-meter nias seem muab kwv yees li 0.45 vib nas this ntawm lub sijhawm nyob hauv ib lub thawv - txaus rau nrawm- teeb tsa cov nplaum nplaum kub tab sis tsis txaus rau cov kua nplaum txias, uas yuav tsum tau ob peb feeb los tsim lub zog ntsuab.
Nias Platens
Ntawm cov tshuab qeeb qeeb lossis reciprocating- cov tshuab ua haujlwm ua cov thawv loj, pneumatically actuated pressing platens siv quab yuam rau cov kua nplaum rau lub sij hawm ruaj khov nyob rau hauv txhua lub voj voog tshuab. Txoj hauv kev no muab kev tswj tau ntau dua thiab tsis sib xws tab sis txwv kev tsim khoom nrawm piv rau kev nruam- siv txoj siv.
7. Erection vs. Flat-Fold Output
Ib qho tseem ceeb sib txawv hauv lub thawv tsis siv neeg lub thawv ua tshuab yog seb lub tshuab xa tuaj:
Pav ca -folded cartons- lub thawv yog tsim nrog tag nrho plaub sab panels folded thiab seam glued, tab sis lub thawv yog vau rau hauv compact cia thiab shipping. Qhov no yog hom ntawv tso zis ntau tshaj plaws. Lub thawv yog tsim rau hauv nws lub thawv zaum kawg ntawm qhov chaw ntawm qhov txhaws, manually lossis los ntawm cov ntaub ntawv downstream erector.
Erected thiab kaw cartons- lub tshuab tsis tsuas yog tsim lub raj xwb tab sis kuj txhim kho lub thawv, folds thiab seals hauv qab flaps, thiab qee zaum sau thiab kaw rau saum. Txoj kev sib koom ua ke no muaj ntau nyob rau hauv siab - ntim khoom noj ceev thiab cov khoom siv tshuaj uas muaj cov ntaub ntawv sib cais- kauj ruam txhim kho yuav tsim kom muaj kev tsim khoom.
Lub hauv paus ntsiab lus ntawm kev siv tshuab sib txawv ntawm ob qhov kev tso tawm no: tiaj-fold tshuab ua tiav lawv cov haujlwm ntawm cov kua nplaum; erect-thiab- cov tshuab foob txuas ntxiv folding, tucking, thiab nias chaw nres tsheb hauv qab ntawm lub raj- ua ntu.
8. Tswj thiab Synchronization: Lub Tshuab Nrawm
Tag nrho cov txheej txheem txheej txheem tau piav qhia saum toj no - pub, ua ntej-folding, folding, gluing, nias - ua haujlwm ib txhij, txhua qhov ua haujlwm sib txawv ntawm qhov sib txawv ntawm qhov sib lawv liag. Nyob rau lub sijhawm twg los xij, lub tshuab yuav muaj nees nkaum lossis ntau dua qhov khoob hauv ntau theem ntawm kev tsim txav los ntawm lub tshuab hauv cov kwj tsis tu ncua.
CovPLC (Programmable Logic Controller)yog lub tshuab synchronization uas tswj txhua lub sijhawm ua haujlwm hauv lub tshuab. Nws tau txais txoj hauj lwm tawm tswv yim los ntawm teb encoders ntawm lub ntsiab tsav ncej thiab ua rau txhua tus actuator - kua nplaum nozzle qhib / kaw, quav hniav ua kom, nias platen voj voog - ntawm qhov tseeb angular txoj hauj lwm sib raug rau qhov chaw dawb paug.
Servo-tsav axes hloov kho- iav mechanical drives ntawm cov tshuab niaj hnub, tso cai rau lub tshuab hloov lub sij hawm tsis sib txawv rau cov thawv loj sib txawv los ntawm cov ntawv qhia kev hloov pauv software es tsis yog lub cev iav lossis cam swaps. Qhov no yog qhov tseem ceeb ntawm kev hloov pauv sai ntawm niaj hnub no ntau -SKU cov kab ntim khoom.
