Uyini umshini wokupakisha uphawu lokugcwalisa ifomu ozenzakalelayo ozenzakalelayo?

Umshini wokupakisha ozenzakalelayo ogcwalisa ifomu eliqondile , owaziwa nangokuthi i-VVFS, uwumshini wokufaka izikhwama odumile osheshayo osetshenziswa ukupakisha izinhlobo ezahlukene zezimpahla njengengxenye yenqubo efana nokukhiqiza. Kuyini ukusetshenziswa kwazo zonke lezi ntuthuko zobuchwepheshe uma amabhizinisi engazisebenzisi ngendlela ezuzisayo emsebenzini wawo? Kungakhathaliseki ukuthi upakisha imikhiqizo yokudla eyomile noma emanzi, imishini ye-Smart Weigh inikeza ubuchwepheshe obufanele bonke amakhasimende ukuze bandise umkhiqizo wabo ngenkathi begcina ubuqotho bomkhiqizo.

Umshini uqala ngokusiza ekwakheni isikhwama nge-roll stock. Njengoba inqubo iqala, umshini uphakela ifilimu phezu kwepayipi elinomumo wekhoni elibizwa ngokuthi i-forming tube elibe selibumba ifilimu libe usayizi wesikhwama onembile bese livala phansi kanye nomthungo oqondile ukuqinisekisa ukuthi akukho ukulahleka komkhiqizo. Ububanzi besikhwama bunqunywa ukwakheka kwepayipi lokwakha, kuyilapho umshini wokufaka izikhwama unquma ubude. Umsebenzisi angashintsha ngokushesha ububanzi besikhwama ngokusishintsha epayipini lokwakha elisha. Izimpawu ziza ngezimo nobukhulu obuhlukahlukene, kodwa izimpawu ze-lap kanye nezijabulisayo yizona ezivame kakhulu. Imiphetho emibili yefilimu iyahlangana futhi ibanjwe ndawonye ku-lap seal, ngemuva kohlangothi oluphezulu luvalwa ngaphambili kohlangothi olungezansi. Ipayipi lokwakha lidonsa imiphetho yefilimu ndawonye ukuze libophe izindawo zangaphakathi ndawonye ku-fin seal.

Ukufaka amafayela kuyisigaba esilandelayo enkambisweni esenziwa ngokuxhuma umshini obambezelayo esikalini esinamakhanda amaningi noma komunye umshini wokufaka amafayela njengesikali samakhanda amaningi . Njengoba le mishini emibili ixhunywe ngogesi, umkhiqizo ufakwa ngokuzenzakalelayo esikhwameni ngokushesha nje lapho usulungile.

Isinyathelo sokugcina sihilela ukuvala nokuqeda umkhiqizo uma usungaphakathi kuwo. Ingxenye ephezulu yesikhwama iyavalwa, bese isikhwama siqedwa bese sinqunywa. Kuholela ekuvalekeni okuphezulu kobubi bokuqala kube phansi kobubi obulandelayo, futhi inqubo iyaziphinda nayo yonke imikhiqizo. Ngesikhathi senqubo yokugcina yokuvala, kungenzeka ukuthi isikhwama sigcwaliswe umoya ovela kumshini wokuphefumula noma igesi engasebenzi njenge-nitrogen. Le nqubo yenziwa ukusiza ukunciphisa ukuchotshozwa kwemikhiqizo ebuthakathaka njengamabhisikidi. Inzuzo eyengeziwe ukuthi i-inert inayo, esiza ukukhipha umoya-mpilo futhi ivimbele ukukhula kwanoma yiliphi igciwane noma isikhunta esingalimaza ikhwalithi yomkhiqizo. Ukuphela komkhiqizo wokugcina ukubhoboza okusetshenziselwa ukuthengisa umkhiqizo owenziwa ngemuva kokuba i-Top seal yenziwe.

Lolu hlelo lokupakisha olusezingeni eliphezulu lungapakisha kokubili izinto eziqinile kanye noketshezi, okwenza kube yindlela yokupakisha engabizi futhi esindisa isikhathi. I-VFFS ibalwa njengenye yemishini ethuthuke kakhulu emakethe njengoba yakhelwe ukupakisha umkhiqizo. Namuhla, isetshenziswa cishe kuyo yonke imboni ngenxa yezixazululo zayo zokupakisha ezisheshayo nezingabizi ezisiza ekugcineni indawo ebalulekile yephansi lezitshalo.
