Vertical fomu zadza chisimbiso (VFFS) machina ekurongedzaanoshandiswa munenge maindasitiri ese nhasi, nechikonzero chakanaka: Iwo anokurumidza, ehupfumi ekurongedza mhinduro inochengetedza yakakosha chirimwa nzvimbo yepasi.
Kunyangwe iwe uri mutsva kumakina ekurongedza kana watova nemasystem akawanda, mukana urikuda kuziva kuti anoshanda sei.Muchinyorwa chino, tiri kufamba nenzira iyo yakatwasuka fomu yekuzadza chisimbiso muchina unoshandura mupumburu wepakeji firimu kuita musherufu-wakagadzirwa bhegi.
Michina yekurongedzera yakapfava, yakamira yakamira inotanga nemupumburu muhombe wefirimu, woigadzira kuita bhegi chimiro, kuzadza bhegi nechigadzirwa, uye kuinamisa, zvese nenzira yakatwasuka, nekumhanya kunosvika mazana matatu emabhegi paminiti.Asi pane zvakawanda kwazviri kupfuura izvozvo.
1. Firimu Yekufambisa & Unwind
Machina ekurongedza anoshandisa pepa rimwechete remafirimu akatenderedzwa kutenderedza musimboti, anowanzo kunzi rollstock.Iyo inoenderera kureba yekurongedza zvinhu inonzi iyo firimu webhu.Izvi zvinogona kusiyana kubva ku polyethylene, cellophane laminates, foil laminates uye mapepa laminates.Mupumburu wefirimu unoiswa pamusangano wespindle kumashure kwemuchina.
Kana muchina wekurongedza weVFFS uchishanda, firimu rinowanzo kudhonzwa kubva pamupumburu nemabhandi ekufambisa kwemafirimu, anoiswa padivi pechubhu yekugadzira iyo iri pamberi pemuchina.Iyi nzira yekufambisa ndiyo inonyanya kushandiswa.Pane mamwe mamodheru, shaya dzinovhara pachadzo dzinobata firimu uye dzichiikwevera pasi, dzichiitakura nemuchina wekurongedza pasina kushandisa mabhandi.
Imwe sarudzo yemotor-driven surface unwind vhiri (power unwind) inogona kuiswa kuti ityaire bhaisikopo serubatsiro pakutyaira kwemabhandi maviri ekufambisa kwemafirimu.Iyi sarudzo inovandudza nzira yekusunungura, kunyanya kana iyo firimu rolls inorema.
2. Firimu Tension
vffs-packaging-machine-film-unwind-and-feedingPanguva yekusunungura, firimu harina kukuvara kubva mupumburu uye rinopfuura nepamusoro peruoko rwekutamba rinova ruoko rwakaremerwa rwepivot rwunowanikwa kumashure kweVFFS yekurongedza muchina.Ruoko runobatanidza nhevedzano yema rollers.Sezvo firimu rinotakura, ruoko runofamba kumusoro uye pasi kuti uchengetedze firimu pasi pekunetseka.Izvi zvinoita kuti firimu rirege kudzungaira richienda kune rimwe divi sezvarinenge richifamba.
3. Optional Printing
Mushure memutambi, firimu rinobva rafamba nepakati pekudhinda, kana imwe yakaiswa.Printer anogona kunge ari thermal kana ink-jet type.Mudhinda anoisa mazuva/makodhi anodiwa pafirimu, kana kuti anogona kushandiswa kuisa mamakisi ekunyoresa, mifananidzo, kana marogo pafirimu.
4. Firimu Tracking uye Positioning
vffs-packaging-machine-film-tracking-positioningKamwe firimu rapfuura pasi peprinta, rinopfuura nekunyoresa foto-ziso.Ziso remufananidzo wekunyoresa rinoona chiratidzo chekunyoresa pafirimu rakadhindwa uyezve, rinodzora mabhandi ekudhonza-pasi achisangana nefirimu pachubhu yekugadzira.Kunyoresa foto-ziso rinochengeta firimu rakamira zvakanaka saka firimu richachekwa panzvimbo yakakodzera.
Tevere, iyo firimu inofamba yakapfuura firimu yekutevera sensors inoona nzvimbo yefirimu pairi kufamba nemuchina wekurongedza.Kana masensa akaona kuti mupendero wefirimu unosimuka kubva panzvimbo yakajairika, chiratidzo chinogadzirwa kufambisa actuator.Izvi zvinokonzera kuti ngoro yose yefirimu ichinje kune rimwe divi kana rimwe sezvinodiwa kuunza mupendero wefirimu kudzokera panzvimbo yakarurama.
5. Kugadzira Bag
vffs-packaging-machine-forming-tube-assemblyKubva pano, iyo firimu inopinda mumusangano wekugadzira tube.Sezvo ichisveta bendekete (collar) pachubhu yekugadzira, inopetwa ichitenderedza chubhu kuitira kuti magumo ave kureba kwefirimu nemapendero maviri ekunze emufirimu anopindirana.Uku ndiko kutanga kwekugadzirisa bhegi.
Iyo yekugadzira chubhu inogona kumisikidzwa kuita chisimbiso chepamakumbo kana chisimbiso chekupedzisira.Chisimbiso chinoputira mativi maviri ekunze emufirimu kugadzira chisimbiso chakati sandara, nepo chisimbiso chekupedzisira chinoroora mukati memativi maviri ekunze emupendero wefirimu kugadzira chisimbiso chinonamira kunze, sechimbi.Chisimbiso chemakumbo chinowanzoonekwa sechinofadza uye chinoshandisa zvinhu zvishoma pane chisimbiso chekupedzisira.
Rotary encoder inoiswa pedyo nebendekete (collar) yechubhu yekugadzira.Iyo firimu inofamba inosangana ne encoder vhiri inoityaira.Pulse inogadzirwa kwehurefu hwese hwekufamba, uye izvi zvinoendeswa kuPLC (programmable logic controller).Kureba kwebhegi kunoiswa pachikirini cheHMI (human machine interface) senhamba uye kana izvi zvangosvika panomira firimu (Pamichina inofamba inomira chete. Michina inofamba haimire.)
Iyo firimu inodhonzwa pasi nemagiya maviri egiya anotyaira kukweshera-kudzika mabhandi ari pamativi ese echubhu yekugadzira.Dhonza mabhandi anoshandisa vacuum suction kubata firimu rekurongedza rinogona kutsiviwa nemabhandi ekukwenya kana uchida.Mabhandi efriction anowanzo kukurudzirwa kune zvigadzirwa zvine guruva sezvo ivo vachiona kushoma kupfeka.
6. Bhegi Kuzadza uye Kuisa Chisimbiso
VFFS-packaging-machine-horizontal-seal-barsZvino firimu richambomira kwenguva pfupi (pamichina yekurongedza inofamba) kuitira kuti bhegi rakaumbwa rigamuchire chisimbiso charo chakamira.Iyo vertical seal bar, iyo inopisa, inoenda kumberi uye inobata neyakagadzika kupindirana pafirimu, ichibatanidza zvidimbu zvefirimu pamwechete.
Pane inoenderera inofamba VFFS yekurongedza midziyo, yakamira yekuisa chisimbiso nzira inoramba ichisangana nefirimu nguva nenguva saka firimu harifanire kumira kuti rigamuchire musono waro wakamira.
Tevere, seti yekudziya yakachinjika yekuisa chisimbiso shaya dzinouya pamwechete kugadzira chisimbiso chepamusoro chebhegi uye chisimbiso chepasi chebhegi rinotevera.Pamakina ekurongedza eVFFS anopindirana, firimu rinosvika pakumira kuti rigamuchire chisimbiso charo chakachinjika kubva mushaya dzinofamba mukuvhurika-kuvhara.Pamichina yekurongedza inofamba, shaya pachadzo dzinofamba dzichikwira-pasi uye dzakavhurika-kuvhara-kuvhara bhaisikopo parinenge richifamba.Mimwe michina inofamba inofamba inotova nemaseti maviri ekusunga shaya kuti awedzere kukurumidza.
Imwe sarudzo ye 'inotonhora sealing' system ndeye ultrasonics, inowanzoshandiswa mumaindasitiri ane zvinopisa-sensitive kana messy zvigadzirwa.Ultrasonic sealing inoshandisa vibrations kuti iite friction pa molecular level iyo inoburitsa kupisa chete munzvimbo iri pakati pemafirimu akaturikidzana.
Nepo shaya dzekuisa chisimbiso dzakavharwa, chigadzirwa chiri kuputirwa chinodonhedzwa pasi nepakati pegomba rekugadzira chubhu uye kuzadzwa mubhegi.Chishandiso chekuzadza senge yakawanda-yemusoro chiyero kana auger kuzadza ndiyo ine basa reiyo kuyerwa uye kuburitswa kwehuwandu hwehuwandu hwechigadzirwa kuti hudonhe mubhegi rega rega.Aya mafirita haasi akajairwa chikamu cheVFFS yekurongedza muchina uye anofanirwa kutengwa kuwedzera kumuchina wacho.Mazhinji mabhizinesi anobatanidza filler nemuchina wavo wekurongedza.
7. Bag Discharge
vffs-packaging-machine-dischargePashure pokunge chigadzirwa chacho chabudiswa muhomwe, banga rinopinza mukati mekupisa chisimbiso shaya rinoenda mberi uye rinocheka bhegi.Rushaya runovhurika uye bhegi rakaputirwa rinodonha.Uku ndiko kuguma kwechikamu chimwe pamushini wekutakura wakatwasuka.Zvichienderana nemuchina uye rudzi rwebhegi, VFFS midziyo inogona kupedzisa pakati pemakumi matatu ne300 emadhizaini paminiti.
Bhegi rakapedzwa rinogona kubuditswa mumudziyo kana pamutakuri uye kutakurwa kuenda kumidziyo yekudzikisa senge cheki weighers, x-ray muchina, kese kurongedza, kana katoni kurongedza midziyo.
