Isebenza kanjani imishini yokufaka i-vertical fill pearl powder? Imishini yokufaka i-vertical fill seal isetshenziswa cishe kuyo yonke imboni namuhla, futhi ngesizathu esihle: iyisisombululo sokupakisha esisheshayo nesonga imali esisindisa isikhala esibalulekile sendawo yefektri. Kungakhathaliseki ukuthi umusha emishinini yokufaka noma usuvele unolwazi ngezinhlelo eziningi, cishe unesifiso sokwazi ukuthi zisebenza kanjani. Kulesi sihloko, ngizokwethula ukuthi umshini we-vertical filling pearl powder ungawuguqula kanjani umqulu wefilimu yokufaka ibe yisikhwama esiqediwe eshalofini.

Umshini wokupakisha owenziwe lula uqala ngomqulu omkhulu wefilimu, uwufake esikhwameni, ugcwalise isikhwama ngomkhiqizo, bese usivala siqonde phezulu, ngesivinini esiphezulu sezikhwama ezingu-300 ngomzuzu. Kodwa kukhona okunye. 1. Ukuvula ngokuzenzakalela Ukupakisha okuqondile kusebenzisa ungqimba olulodwa lwezinto zefilimu (ngokuvamile ezibizwa ngokuthi iwebhu) olugoqeka ngaphakathi.

Ubude obuqhubekayo bezinto zokupakisha bubizwa ngokuthi iwebhu yefilimu. Izinto zingahluka kune-polyethylene, i-cellophane laminates, i-foil laminates kanye ne-paper laminates. Beka ifilimu ku-spindle assembly ngemuva komshini.

Uma umshini wokupakisha usebenza, ifilimu ivame ukukhishwa emqulwini yi-conveyor yefilimu, etholakala ohlangothini lwepayipi lokwakha ngaphambili komshini. Le ndlela yokuthumela iyona esetshenziswa kakhulu. Kwamanye amamodeli, imihlathi yokuvala ibamba ifilimu bese iyidonsa phansi, okuvumela ukuthi ithuthwe ngepakethe ngaphandle kwesidingo sebhande.

Isondo lokuvula indawo eliqhutshwa yinjini elingafakwa ukuze lishayele ifilimu ukusiza ekushayeleni ama-conveyor amabili efilimu. Lolu khetho luthuthukisa inqubo yokuvula, ikakhulukazi uma ifilimu inzima. 2. Ukucindezeleka kwefilimu Ngesikhathi senqubo yokuvula, ifilimu iyasuswa emqulwini bese idlula engalweni entantayo, okuyingalo ejikelezayo ephikisana nesisindo etholakala ngemuva komshini wokupakisha.

Izingalo zifakwe uchungechunge lwama-roller. Ngesikhathi sokuthutha ifilimu, ingalo iya phezulu naphansi ukuze ifilimu igcinwe icindezelekile. Lokhu kuqinisekisa ukuthi ifilimu ayinyakazi ukusuka kolunye uhlangothi kuya kolunye njengoba ihamba.

3. Ukuphrinta okukhethwa kukho Uma ifilimu ifakiwe, ngemva kokuba ifilimu isidlule kumphathi wefilimu, izodlula kuyunithi yokuphrinta. Iphrinta ingaba iphrinta yokushisa noma iphrinta ye-inkjet. Iphrinta ibeka usuku/ikhodi oyifunayo kufilimu, noma ingasetshenziswa ukubeka izimpawu zokubhalisa, ihluzo noma ama-logo kufilimu.

4. Ukulandelela nokubeka ifilimu Ngemva kokuba ifilimu idlule ngaphansi kwephrinta, izodlula esweni lekhamera yokubhalisa. Iso lesithombe sokubhalisa libona izimpawu zokubhalisa efilimini ephrintiwe bese lilawula ibhande lokudonsa phansi ukuze lixhumane nefilimu epayipini elakhayo. Gcina ifilimu isendaweni efanele ngokuqondisa amehlo esithombe ukuze ifilimu isikwe endaweni efanele.

Okulandelayo, ifilimu idlula ku-sensor yokulandelela ifilimu, ethola indawo yefilimu njengoba ihamba emshinini wokupakisha. Uma i-sensor ithola ukuthi unqenqema lwefilimu luyaphambuka endaweni yalo evamile, ikhiqiza isignali yokuhambisa i-actuator. Lokhu kubangela ukuthi lonke inqola yefilimu ihambe iye kolunye uhlangothi noma kolunye njengoba kudingeka ukuze kubuyiselwe unqenqema lwefilimu endaweni efanele.

5. Ukwakheka kwesikhwama Kusukela lapha ifilimu ingena ekuhlanganisweni kweshubhu yokwakha. Uma ibhekene nehlombe (ikhola) leshubhu yokwakha, igoqwa phezu kweshubhu yokwakha ukuze umphumela wokugcina ube yifilimu ubude obunemiphetho emibili yangaphandle yefilimu ihambisana. Lokhu kungukuqala kwenqubo yokwenza isikhwama.

Ithubhu elakhiwe lingalungiselelwa ukuvala i-lap noma i-fin seal. Ukuvala i-lap seal kugoqa imiphetho emibili yangaphandle ye-membrane ukuze kwakheke uphawu oluyisicaba, kuyilapho uphawu lwe-fin luhlangana nengaphakathi lemiphetho emibili yangaphandle ye-membrane ukuze kwakheke uphawu oluphuma njenge-fin. Izivalo ze-lap seal ngokuvamile zibhekwa njengezinhle kakhulu futhi zisebenzisa izinto ezincane kunezivalo ze-fin.

I-encoder ejikelezayo ibekwa eduze kwehlombe (i-flange) lepayipi elakhiwe. Ifilimu ehambayo ethintana nesondo le-encoder iyishayela. Ukunyakaza ngakunye kudala i-pulse bese kuyidlulisela ku-PLC (Programmable Logic Controller).

Ubude besikhwama busethwa ngezinombolo esikrinini se-HMI (Human Machine Interface), futhi uma lokhu kulungiselelwa sekufinyelelwe, ukuthuthwa kwefilimu kuyama (Emishinini yokunyakaza eqhubekayo kuphela. Imishini yokunyakaza okuqhubekayo ayimi.) Ifilimu idonswa phansi yizinjini ezimbili zegiya, izinjini zegiya zishayela amabhande okungqubuzana okudonsa phansi kuzo zombili izinhlangothi zepayipi elibumbayo.

Uma uthanda, ibhande lokudonsa phansi elisebenzisa i-vacuum suction ukuqinisa ifilimu yokupakisha lingasetshenziswa esikhundleni sebhande lokukhuhlana. Amabhande okukhuhlana ngokuvamile anconywa emikhiqizweni enothuli ngoba agugi kakhulu. 6. Ukugcwaliswa kwezikhwama nokuvala Manje ifilimu izoma isikhashana (ku-packer yokunyakaza eqhubekayo) ukuze isikhwama esibunjiwe sithole uphawu lwaso oluqondile.

I-hot vertical seal iya phambili futhi ithintane nokugqagqana okuqondile efilimini, ihlanganisa izendlalelo zefilimu ndawonye. Emishinini yokupakisha eqhubekayo, indlela yokuvala eqondile ihlala ithintana nefilimu, ngakho ifilimu ayidingi ukuma ukuze ithole umthungo wayo oqondile. Okulandelayo, isethi yemihlathi yokuvala evundlile efudumele iyahlanganiswa ukuze yakhe uphawu oluphezulu lwesikhwama esisodwa kanye nophawu oluphansi lwesinye.

Emishinini yokufaka amaqoqo, ifilimu iyama bese imihlathi inyakaza ngesenzo sokuvula nokuvala ukuze kutholakale uphawu oluvundlile. Emishinini yokufaka amaqoqo enyakaza njalo, imihlathi ngokwayo ingashukunyiswa phezulu naphansi, noma ngokuvula nokuvala ukuvala ukuvala ifilimu. Eminye imishini yokuhamba njalo inamaqoqo amabili emihlathi evaliwe ukuze kukhuphuke isivinini.

I-Ultrasonic iyindlela yokukhetha izinhlelo "zokuvala okubandayo", ezivame ukusetshenziswa ezimbonini ezinemikhiqizo ezwela ukushisa noma engcolile. Ukuvala nge-Ultrasonic kusebenzisa ukudlidliza ukuze kubangele ukungqubuzana ezingeni lama-molecule, okudala ukushisa kuphela ezindaweni eziphakathi kwezingqimba ze-membrane. Ngenkathi kuvalwa imihlathi yokuvala, umkhiqizo ozopakishwa wehliswa usuka phakathi kwepayipi eliyimbobo bese ugcwaliswa esikhwameni.

Imishini yempuphu yamaparele, njengesikali samakhanda amaningi noma umshini wempuphu yamaparele ohlobo lwesikulufo, inesibopho sokulinganisa kahle nokukhulula inani elihlukile lomkhiqizo okufanele lifakwe esikhwameni ngasinye. Le mishini yempuphu yamaparele ayiyona ingxenye ejwayelekile yemishini yokupakisha futhi kumele ithengwe ngaphezu komshini uqobo. Amabhizinisi amaningi ahlanganisa umshini wempuphu yamaparele nomshini wokupakisha.

7. Ukukhipha isikhwama Ngemva kokufaka umkhiqizo esikhwameni, ummese obukhali emhlathini wokuvala ukushisa uya phambili bese usika isikhwama. Imihlathi iyavuleka bese isikhwama esipakishiwe siyawa. Lokhu ukuphela komjikelezo emshinini wokupakisha oqondile.

Kuye ngohlobo lomshini nesikhwama, imishini yokupakisha ingenza imijikelezo engama-30 kuya kwangu-300 ngomzuzu. Izikhwama eziqediwe zingathululwa ezitsheni noma kuma-conveyor bese zithuthwa ziye emishinini yokugcina izinto efana nama-checkweighers, imishini ye-X-ray, imishini yokupakisha amabhokisi noma imishini yokupakisha amabhokisi.
