The requirements of high-speed paper bowl forming machines for raw materials (paper bowl base paper and PE-coated paper), as well as the impact of raw material characteristics on forming quality, can be analyzed from three dimensions: functionality, adaptability, and stability. Nov yog cov ntsiab lus:
1. Cov tseev kom muaj ntawm high- ceev daim ntawv ua machine rau cov ntaub ntawv raw
1.1 yuav tsum rau daim ntawv ntim khoom ntim
Cov ntsuas ntsuas:
Lub zog tensile: Nws yuav tsum ua kom tau raws li kev ncab thiab curling thiab curling xav thaum lub siab siab - Ceev conveying thiab kev tsim kom tiv thaiv tawg.
Nruj: Nws yuav tsum xyuas kom lub hauv paus ntawv tsis yooj yim deformed thaum noj thiab curling -}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} Tsis muaj tus txheej txheem ruaj khov thaum tsim lub tais lub cev.
Burst Kuj: Nws yuav tsum tau tiv thaiv cov ntawv txheej kev puas tsuaj vim yog los ntawm extrusion thiab folding thaum tsim.
Lub cev ruaj khov:
Yauv cov ntsiab lus: Nws yuav tsum tau tswj hwm ntawm 6% thiab 8% (ntau dhau noo ua rau lub hauv paus ntawv mos mos ua rau lub hauv paus tsis ruaj khov;
Kev sib dhos fiber ntau: Daim ntawv saum npoo yuav tsum yog dawb ntawm wrinkles, qhov, thiab impurities kom tsis txhob muaj busging los yog tsis sib xws hauv lub tais lub cev.
Qhov Tseeb Sab Nraum:
Qhov dav thiab ntev sib txawv ntawm lub hauv paus ntawv yob yuav tsum tsawg dua lossis sib npaug rau cov khoom noj mis, tiv thaiv kev ua yuam kev los ntawm qhov tsis sib xws.
1.2 YUAV TSUM TAU RAU PE -} coated ntawv
Txheej Txheej Txheej Tej yam:
TXHEEJ KHOOM SIV: Zaub mov {{{{{}} qib polyethylene (PE) yuav tsum tau siv, ua raws li cov qauv kev nyab xeeb rau kev nyab xeeb xws li GB 4806.7. Nws yuav tsum tsis muaj ntxhiab thiab kua qaub - {{{tiv taus cov tshuaj tiv thaiv kev ua kom tsis txhob raug mob thaum tuav zaub mov).
Txheej Thickness: Nws yuav tsum tau hloov kho raws li kev siv (30-50μ m 2}}}}}}} {{5} {5} {5} dej haus hauv qab). Thickness uniformity sib txawv yuav tsum tsawg dua los yog sib luag rau 5μm (ntau dhau nyias muaj kev pheej hmoo ua kom cov nqi thiab tabkaum tsim).
Siv lub zog:
Lub zog tev ntawm daim ntawv thiab PE txheej yuav tsum yog ntau dua los yog sib npaug ntawm kev tsim cov txheej txheem (piv txwv li cas} {5} -
Thermal ruaj khov:
PE txheej txheej yuav tsum muaj lub zog melting point (feem ntau 105-130 degree). Nws yuav tsum qhuav uniformly thiab solorify saws sai sai, txuam cov khoom siv thaum tshav kub {}} sealing kub (feem ntau 150-200 degree).
2. Cov kev cuam tshuam tshwj xeeb ntawm cov khoom nyoos cov yam ntxwv ntawm kev ua kom zoo
2.1 cuam tshuam ntawm cov ntawv tuab tuab
Ntawm Kev Ua Haujlwm Kev Ua Haujlwm:
Ntau dhau tuab tuab: Cov ntawv hauv paus ua kom nruj dua, ua rau nws nyuaj kom haum kom nruj thaum uas sib khi lub tais rau hauv qab. Qhov no yuav ua rau muaj kev sib cuag dhau ntawm cov khoom sib raug zoo, ua rau muaj teeb meem ceev, qhov twg ua rau nws muaj teeb meem ceev rau cov ntawv tuab tuab.
Ntau dhau nyias nyias: Thaum nyias cov ntawv nyias nyias yooj yim, nws muaj lub tensile tsis zoo. Tom qab kev sib raug zoo, sab nraud yuam (piv txwv li, nthuav tawm thaum tuav zaub mov) tej zaum yuav rhuav nws, ua rau tawg ntawm cov pob qij txha sib tua.
Ntawm lub tais Ntug tiaj:
Tsis ncaj siv thickness: Localized thick areas of the base paper create uneven force during rim curling, resulting in skewed curls and height differences (a deviation >0.3mm yog suav hais tias tsis muaj qhov tsis tsim nyog).
Ntau dhau tuab tuab: Daim ntawv yog qhov nyuaj rau curl uniformly thaum lub sij hawm curlings, nquag lub tais Rim lub peev xwm sib luag (piv txwv li lub hau zoo ntxiv).
2.2 Kev cuam tshuam ntawm PE Txheej Txheej Txheem
Ntawm Kev Ua Haujlwm Kev Ua Haujlwm:
Uneven txheej (hauv zos nyias lossis khoob): Thaum tshav kub khi, tsis txaus melting ntawm PE txheej txheej tiv thaiv txheej txheej ntawm ib qho kev sib khi ua kom muaj zog, txo qhov tsis muaj zog- Thaum tuav kua.
Hauv zos tshaj - tuab: Melted pe hauv cov thaj chaw tuab muaj cov xim tsis zoo, muaj peev xwm sib sau "kev sib txuam" ntawm qhov sib raug zoo. Tom qab txias, ua kom tawv nqaij tawv, ua rau tsis muaj kev cuam tshuam tsis sib haum xeeb ntawm cov chaw sib raug zoo, uas yuav tawg ntawm thaj chaw tuab ntawm lub sijhawm.
Ntawm lub tais Ntug tiaj:
Cov txheej txheem tseem ceeb thickness sib txawv: Thicker PE Thaj tsam tsis haum cua sov thaum lub sij hawm curling, ua rau muaj ntau qhov chaw thiab ua rau muaj kev sib tw hauv zos lossis kev tawm tsam ntawm lub tais Rim. Conversely, tej thaj chaw nyias yuav tsis muaj kub tiv thaiv, tau qhab nia thaum lub sijhawm curling thiab ua kom puas tiaj.
2.3 Lwm cov kev cuam tshuam tseem ceeb (ncua sau)
Teeb Ntawv Fiber Ntau: Tsis muaj kev cuam tshuam fiber ntau ua rau muaj kev sib cav sib ceg ntawm lub hauv paus lub cev thiab tsis ncaj rau cov suab nrov ntawm lub tais Rim thiab hauv qab.
PE Txheej cua sov ua tau: Yog tias tus PE txheej Lauj tsis muaj cov cua sov ua kom tsis kam (piv txwv li, siv qis {}}}}}}}}}}}} Cov kua kub kom muaj deform lossis txawm tias txoj kev poob.
