Isebenza kanjani imishini yokufaka i-pearl powder yokugcwalisa mpo? Imishini yokupakisha ye-vertical fill seal isetshenziswa cishe kuyo yonke imboni namuhla, futhi ngesizathu esihle: iyisixazululo sokupakisha esisheshayo, esinomnotho esilondoloza indawo ebalulekile yefekthri. Noma ngabe umusha emshinini wokupakisha noma usuvele unolwazi ngamasistimu amaningi, cishe ufuna ukwazi ukuthi asebenza kanjani. Kulesi sihloko, ngizokwethula ukuthi umshini wokugcwalisa i-pearl powder oqondile ungashintsha kanjani umqulu wefilimu yokupakisha ibe isikhwama esiphelile eshalofini.

Umshini wokupakisha ome mpo owenziwe lula uqala ngomqulu omkhulu wefilimu, uwufake esikhwameni, ugcwalise isikhwama ngomkhiqizo, bese usivala sibheke phezulu, ngesivinini esiphezulu sezikhwama ezingu-300 ngomzuzu. Kodwa kukhona okwengeziwe. 1. Ukuzikhulula okuzenzakalelayo Ukupakisha okuqondile kusebenzisa ungqimba olulodwa lwento yefilimu (evame ukubizwa ngokuthi iwebhu) egoqeka phakathi nendawo.

Ubude obuqhubekayo bempahla yokupakisha bubizwa ngokuthi iwebhu yefilimu. Izinto ezibonakalayo zingahluka ku-polyethylene, i-cellophane laminates, i-foil laminates nama-laminates wephepha. Beka ifilimu kumhlangano wokuphotha ngemuva komshini.

Lapho umshini wokupakisha usebenza, ifilimu ngokuvamile ikhishwa kumqulu umshini ohambisa ifilimu, obekwe eceleni kweshubhu elenzayo elingaphambi komshini. Le ndlela yokuthutha iyona esetshenziswa kakhulu. Kwamanye amamodeli, imihlathi yokufaka uphawu ngokwayo ibamba ifilimu bese iyidonsa phansi, ivumela ukuba ihanjiswe ngepakethe ngaphandle kwesidingo sebhande.

Isondo lokuphumuza indawo elishayelwa ngemoto elingakhethwa lingafakwa ukushayela ifilimu ukusiza ekushayeleni amaconveyor amafilimu amabili. Lolu khetho luthuthukisa inqubo yokuqaqa, ikakhulukazi uma ifilimu isindayo. 2. Ukushuba kwefilimu Ngesikhathi senqubo yokuqaqa, ifilimu iyakhululwa emqulwini futhi idlule engalweni entantayo, okuyingalo ye-pivot ephikisayo etholakala ngemuva komshini wokupakisha.

Izingalo zifakwe uchungechunge lwama-roller. Ngesikhathi sokuthutha ifilimu, ingalo iya phezulu naphansi ukugcina ifilimu ingaphansi kwengcindezi. Lokhu kuqinisekisa ukuthi ifilimu ayinyakazi ngapha nangapha njengoba ihamba.

3. Ukuphrinta ngokuzikhethela Uma ifilimu ifakiwe, ngemva kokuba ifilimu isidlulile kukakaputeni wefilimu, izodlula eyunithi yokuphrinta. Iphrinta ingaba iphrinta eshisayo noma iphrinta ye-inkjet. Iphrinta ibeka idethi/ikhodi efiselekayo efilimini, noma ingasetshenziswa ukubeka izimpawu zokubhalisa, imifanekiso noma amalogo efilimu.

4. Ukulandelela nokubeka ifilimu Ngemva kokuba ifilimu idlule ngaphansi kwephrinta, izodlula esweni lekhamera yokubhalisa. Iso lesithombe sokubhalisa lihlonza amamaki okubhalisa efilimini ephrintiwe bese lilawula ibhande lokudonsela phansi ukuze lithinte ifilimu ekwishubhu elenzayo. Gcina ifilimu isendaweni efanele ngokuqondisa amehlo esithombe ukuze ifilimu isikwe endaweni efanele.

Okulandelayo, ifilimu idlula inzwa yokulandelela ifilimu, ethola indawo yefilimu njengoba ihamba ngomshini wokupakisha. Uma inzwa ithola ukuthi unqenqema lwefilimu luyachezuka endaweni yalo evamile, ikhiqiza isignali ukuhambisa i-actuator. Lokhu kubangela ukuthi yonke inqola yefilimu ihambe iye kolunye uhlangothi noma kolunye njengoba kudingeka ukubuyisela imiphetho yefilimu endaweni efanele.

5. Ukwakhiwa kwesikhwama Ukusuka lapha ifilimu ingena ekuhlanganiseni kwe-tube yokwakha. Uma ithwala ngokumelene nehlombe (collar) ye-tube yokwakha, igoqwe phezu kweshubhu yokwakha ukuze umphumela wokugcina ube ubude befilimu enemiphetho emibili yangaphandle yefilimu ehambisanayo. Lesi yisiqalo senqubo yokwenza isikhwama.

Ishubhu elibunjiwe lingasethwa ukuze libe yi-lap seal noma i-fin seal. I-lap seal idlulela emaphethelweni amabili angaphandle olwelwesi ukuze kwakheke uphawu oluyisicaba, kuyilapho uphawu oluyisiphetho luhlangana nengaphakathi lemiphetho emibili yangaphandle yolwelwesi ukuze kwakhe uphawu oluphuma njengephiko. Ama-Lap seal ngokuvamile abhekwa njengobuhle kakhulu futhi asebenzisa impahla encane kune-fin seal.

Isishumeki esijikelezayo sibekwe eduze kwehlombe (i-flange) leshubhu elakhiwe. Ifilimu egudlukayo exhumene nesondo lomshini wokufaka ikhodi iyayishayela. Ukunyakaza ngakunye kwakha ukushaya kwenhliziyo futhi kukuthumele ku-PLC (Isilawuli Se-Programmable Logic).

Ubude besikhwama busethwe ngokwezinombolo esikrinini se-HMI (Human Machine Interface), futhi uma lesi silungiselelo sesifinyelelwe, okokuthutha kwefilimu kuyama (Emishinini enyakazayo yezikhawu kuphela. Imishini enyakazayo eqhubekayo ayimi.) Ifilimu idonswa phansi ngamagiya amabili. ama-motor, ama-Gear motors ashayela amabhande adonsela phansi adonsela phansi nhlangothi zombili zeshubhu eyakhayo.

Uma uthanda, ibhande lokudonsela phansi elisebenzisa i-vacuum suction ukuze liqinise ifilimu yokupakisha lingasetshenziswa esikhundleni sebhande lokukhuhlana. Amabhande e-Friction ngokuvamile anconywa emikhiqizweni enothuli ngoba agqoka kancane. 6. Ukugcwaliswa kwesikhwama nokuvalwa Manje ifilimu izoma kafushane (kupakisha onyakazayo wezikhawu) ukuze isikhwama esakhiwe sithole uphawu lwaso olume mpo.

Uphawu olushisayo olume mpo luya phambili futhi luthintana nokugqagqana okuqondile kwefilimu, luhlanganisa izendlalelo zefilimu. Emishinini yokupakisha eqhubekayo, indlela yokuvala eqondile ihlala ixhumene nefilimu, ngakho-ke ifilimu ayidingi ukuma ukuze ithole umthungo wayo ome mpo. Okulandelayo, iqoqo lemihlathi yokuvala evundlile eshisayo iboshelwa ndawonye ukuze yakhe uphawu olungaphezulu lwesikhwama esisodwa kanye nophawu olungezansi kwesinye.

Emishinini yokupakisha iqoqo, ifilimu iyama bese imihlathi inyakaza ngokuvula nokuvala ukuze kutholwe uphawu oluvundlile. Emishinini yokupakisha eqhubekayo, imihlathi ngokwayo ingahanjiswa iye phezulu naphansi, noma ngokuvula nokuvala ukunyakaza ukuze kuvalwe ifilimu. Eminye imishini enyakazayo eqhubekayo ize ibe namasethi amabili emihlathi evaliwe ukuze ijubane likhuphuke.

I-Ultrasonic inketho yezinhlelo "zokuvalwa okubandayo", ngokuvamile ezisetshenziswa ezimbonini ezinemikhiqizo ezwela ukushisa noma engcolile. Ukuvalwa kwe-Ultrasonic kusebenzisa ukudlidliza ukuze kubangele ukungqubuzana ezingeni lamangqamuzana, okukhiqiza ukushisa kuphela ezindaweni eziphakathi kwezingqimba zolwelwesi. Ngenkathi uvala imihlathi yokuvala, umkhiqizo ozopakishwa wehliswa usuka phakathi kweshubhu elakhiwe elingenalutho bese ugcwaliswa esikhwameni.

Impahla ye-pearl powder, njengesikali esinamakhanda amaningi noma umshini wempushana we-screw-pearl, inomthwalo wemfanelo wokulinganisa ngendlela efanele kanye nokukhulula amanani ahlukene omkhiqizo okufanele aconselwe esikhwameni ngasinye. Le mishini ye-pearl powder ayiyona ingxenye evamile yemishini yokupakisha futhi kufanele ithengwe ngaphezu komshini ngokwawo. Amabhizinisi amaningi ahlanganisa umshini we-pearl powder nomshini wokupakisha.

7. Ukukhipha isikhwama Ngemva kokufaka umkhiqizo esikhwameni, ummese obukhali emhlathini ovala ukushisa uya phambili futhi usike isikhwama. Imihlathi iyavuleka futhi isikhwama esipakishiwe siyawa. Lesi isiphetho somjikelezo emshinini wokupakisha ome mpo.

Ngokuya ngohlobo lomshini nesikhwama, okokupakisha kungenza ama-30 kuye kwangama-300 ale mijikelezo ngomzuzu. Izikhwama eziqediwe zingalayishwa ezitsheni noma kuma-conveyor futhi zithuthelwe emishinini yokuphela kwesikhathi efana ne-checkweigher, imishini ye-X-ray, ukupakisha amakesi noma okokupakisha amabhokisi.
