Ukuhlaziywa kwesimiso sokusebenza kanye nenqubo yomshini wokupakisha we-thermoforming

Umgomo wokusebenza we umshini wokupakisha we-thermoformingukusebenzisa izici zokushisa nokuthambisa zamashidi epulasitiki anezakhiwo eziqinile ukuze ushaye noma ukhiphe umshini wokupakisha ukwakha isitsha sokupakisha esinezimo ezihambisanayo ngokusho kokwakheka kwesikhunta, bese ulayisha imikhiqizo kanye nokuvala, ukuqoqa ngokuzenzakalelayo imfucuza eyengeziwe ngemuva kokusika futhi ukwakha.Iqukethe ikakhulukazi izingxenye ezilandelayo:

Ukushisisafuthiukwakha indawo

Ngaphambi kokubumba, shisa ifilimu engezansi ukuze ufinyelele izinga lokushisa elidingekayo ekubumbeni futhi ulithambisa, lilungele ukubunjwa ngokushesha.Indlela yokubumba ihlukile ngokobuchwepheshe bomenzi, impahla yefilimu, nokujula kwesitsha esakhayo.

Okulandelayo kwethula ngokuyinhloko izindlela ezimbalwa zokwakha ezivame kakhulu nezisetshenziswa kabanzi emishinini yokupakisha ye-thermoforming:

1) I-Vacuum: Ukwakhiwa kwengcindezi engalungile, vula kusuka phansi kwesikhunta ukuze unamathisele ishidi lilingane nesikhunta ukuze wakhe isitsha sokupakisha, esilungele amashidi amancane futhi asetshenziselwa iziqukathi ezinwetshiwe ezingajulile.

2) Umoya ocindezelwe.Ukwakhiwa kwengcindezi enhle, okwengeza umoya ocindezelwe ovela ngaphezu kwegumbi lokushisisa.Le ndlela inezidingo eziphezulu zobuchwepheshe futhi ifanele ukwelula amashidi aminyene futhi yakhe iziqukathi ezijulile.

3) Engeza umshini wokwelula osizayo osekelwe ku-1 no-2. Isimiso esiyinhloko ukuthi izingcindezi zomoya ezihlukene zakhiwe ezinhlangothini zombili zeshidi.Ngaphansi kwesenzo sokucindezelwa okuhlukile, ishidi licindezelwa phansi eduze naphansi kwesikhunta esakha.Uma ubunzima bokwelula noma ukujula kokubunjwa kukhulu kakhulu, kuyadingeka ukwengeza umshini wokwelula osizayo ukuze usize ukwakha.Le ndlela yokwenza inezidingo eziphezulu zobuchwepheshe zabakhiqizi.Ngaphambi kokuba umoya ocindezelwe uxhumeke, ishidi elishisayo nelithambile linwetshwa kusengaphambili ngekhanda elinwebekayo, ukuze isitsha esakhiwe sibe nokujula okujulile kanye nobukhulu obufanayo ukuze kuhlangatshezwane nezidingo zamakhasimende amaningi.

Ukwelula ukwakheka kwensiza yekhanda

Ngokusebenzisa lezi zindlela ezintathu ezingenhla zokwenza, isikhunta esakhiwe siyapholiswa, futhi sibunjwe sibe yisitsha esifana nokuma kwesikhunta.

Ngemva kokuba selipholile ngokuphelele, libunjwa libe yisitsha esifana nokuma kwesikhunta.

Inqubo yokusebenza yomshini wokupakisha we-thermoforming iboniswa esithombeni esingezansi (ifilimu eguquguqukayo):

1.Indawo yefilimu ephansi: Faka umqulu wefilimu kushafti evuthekayo njengoba kudingeka, qinisekisa ukuthi indawo ilungile, bese uyivuthela ukuze uqinise.Yondla uhlangothi olulodwa lwefilimu engezansi phakathi kwamaketango amabili okubamba kanye nesigubhu.
2.Indawo yokubunjwa: Idluliswa ngeketango, ifilimu engezansi ifinyelela endaweni yokwenza.Kule ndawo ngokwezidingo zamakhasimende, ishidi liyashiswa futhi linwetshwe ngalezi zindlela ezintathu ezingenhla zokwakha (i-vacuum, umoya ocindezelwe, ukunwebeka kwekhanda+umoya ocindezelwe).
I-3.Indawo yokulayisha: Le ndawo ingahlonyiswa ngemishini yokugcwalisa isisindo esizenzakalelayo noma ukugcwaliswa ngesandla ngokwezidingo zamakhasimende.
I-4.Indawo yokufaka uphawu: Ifilimu engezansi nefilimu ephezulu iyashiswa, i-vacuum futhi ivalwe kule ndawo (engeza umsebenzi we-inflate njengoba kudingeka), futhi izinga lokushisa lokuvala lingashintshwa ngokuvumelana nezakhiwo zeshidi.
5.Indawo yokusika: Kunezindlela ezimbili zokusika zale ndawo ngokusho kobukhulu befilimu: Ifilimu eqinile yokusika ingcindezi, ifilimu eguquguqukayo yokusika okuguquguqukayo kanye ne-longitudinal.Ngemuva kokuthi imikhiqizo ivaliwe, ithunyelwa kule ndawo ukuze inqunywe futhi ikhishwe.Ngokwezidingo zamakhasimende, singafaka izinto ezisizayo ezifana nokuhlunga, ukutholwa kwensimbi, ukutholwa kwesisindo nokunye ukuze sakhe umugqa wokukhiqiza ophelele.

Ngemva kweminyaka yocwaningo nokwenza ngcono, umshini wokupakisha we-Utien Pack we-thermoforming wenze ngempumelelo iziqukathi ezijulile ezingu-150 mm, ezinokunemba okuphezulu nokusatshalaliswa kogqinsi kwefilimu efanayo.Ngesikhathi esifanayo, isivinini sethu sokupakisha sesifinyelele izikhathi ezingu-6-8 ngomzuzu, ngaphambi kakhulu kontanga yasekhaya.
