Ukubumba ukuvuthela yinkqubo esetyenziswa ngokubanzi ekwenzeni iinxalenye zeplastiki ezingenanto. Ithandwa kakhulu kwimveliso yeebhotile, iibhotile kunye nezinye iimveliso ezahlukeneyo. Embindini wenkqubo yokubumba kukuvuthelavuthela umatshini wokubumba, edlala indima ebalulekileyo ekubumbeni izinto zeplastiki kwimveliso efunwayo. Kweli nqaku, siza kujonga izigaba ezine zokubumba ukubetha kunye nendlela umatshini wokubumba uququzelela inqanaba ngalinye.
Ngaphambi kokungena kwinqanaba ngalinye, kufuneka uqonde ukuba yintoni na ukubumba ukuvuthela.Ukubumba ukuvuthelayinkqubo yokuvelisa ebandakanya ukuvuthela ityhubhu yeplastiki eshushu (ebizwa ngokuba yiparison,) ibe ngumngundo ukuze yenze into engenamngxuma. Inkqubo iyasebenza kwaye iyafikeleleka, iyenza ibe lukhetho oludumileyo lokuvelisa ubuninzi beemveliso zeplastiki.
Izigaba ezine zokubumba isivuthelo:
Ukubumba ukuvuthela kunokwahlulwa ngokwezigaba ezine ezihlukeneyo: ukukhupha, ukubumba, ukupholisa kunye nokukhupha. Inqanaba ngalinye libaluleke kakhulu kwimpumelelo epheleleyo yenkqubo yokubumba, kunye noomatshini bokubumba bavuthela baququzelele isigaba ngasinye.
1. Extrusion
Inqanaba lokuqala lokubumba i-blow is extrusion, apho iipilisi zeplastiki zondliwa kumatshini wokubumba. Ivuthela umatshini wokubumbaifudumeza iipeliti zeplastiki zide zinyibilike, zenze ityhubhu eqhubekayo yeplastiki enyibilikisiweyo ebizwa ngokuba yiparison. Inkqubo ye-extrusion ibalulekile kuba imisela ubukhulu kunye nokufana kwe-parison, echaphazela ngokuthe ngqo umgangatho wemveliso yokugqibela.
Kweli nqanaba, umatshini wokubumba usebenzisa isikrufu okanye iplunger ukutyhala iplastiki etyhidiweyo kwisingundo ukwenza iprison. Ubushushu kunye noxinzelelo kufuneka kulawulwe ngononophelo ukuqinisekisa ukuba iplastiki inyibilika ngokupheleleyo kwaye inokubunjwa ngokulula kwizigaba ezilandelayo.
2. Ukubumba
Nje ukuba i-parison yenziwe, inqanaba lokubumba lingeniswa. Kweli nqanaba, i-parison ibotshelelwe kubumba ukwenza imveliso yokugqibela. Umatshini wokubumba uvuthela emva koko wazisa umoya kwi-parison, ubangela ukuba wande de uzalise ngokupheleleyo ukungunda. Le nkqubo yaziwa njengokubumba ukuvuthela.
Uyilo lokungunda lubalulekile njengoko lumisela ubungakanani bokugqibela kunye nokugqitywa komphezulu wemveliso. Ngeli nqanaba, umatshini wokubumba kufuneka ulawule ngokuchanekileyo uxinzelelo lomoya kunye nobushushu ukuqinisekisa ukuba i-parison iyanda ngokulinganayo kwaye ibambelele kwiindonga zokubumba.
LQ AS Isitofu-zolula-ivuthelo ukubumba umatshini kwihoseyile
1. Imodeli ye-AS series isebenzisa isakhiwo sezikhululo ezintathu kwaye ifanelekile ukuvelisa izitya zeplastiki ezifana ne-PET, i-PETG, njl.
2. Itekhnoloji yokubumba i-injection-stretch-blow ibandakanya oomatshini, iimolds, iinkqubo zokubumba, njl njl. I-Liuzhou Jingye Machinery Co., Ltd. ibiphanda kwaye iphuhlisa le teknoloji iminyaka engaphezu kweshumi.
3. I-Injection-Stretch-Blow Molding Machine yethu iyisikhululo sesithathu: i-injection preform, i-strentch & blow, kunye ne-ejection.
4. Le nkqubo yenqanaba elinye inokukongela amandla amaninzi kuba akunyanzelekanga ukuba uphinde ufudumeze iipreforms.
5. Kwaye inokuqinisekisa inkangeleko engcono yebhotile, ngokunqanda i-preforms ukukrwela ngokuchaseneyo.
3. Ukupholisa
Emva kokuba i-parison ifakwe umoya kwaye ibunjwe, ingena kwisigaba sokupholisa. Eli nqanaba libalulekile ekunyangeni iplastiki kunye nokuqinisekisa ukuba imveliso yokugqibela igcina ukumila kwayo.Oomatshini bokubumba bavuthelengokuqhelekileyo zisebenzisa imijelo yokupholisa okanye umoya ukunciphisa ubushushu benxalenye ebunjiweyo.
Ixesha lokupholisa liyahluka ngokuxhomekeke kuhlobo lweplastiki esetyenzisiweyo kunye nobukhulu bemveliso. Ukupholisa okufanelekileyo kubalulekile kuba kuchaphazela iimpawu zoomatshini kunye nomgangatho opheleleyo wemveliso yokugqibela. Ukuba inkqubo yokupholisa ayilawulwa ngokufanelekileyo, inokubangela i-warpage okanye ezinye iziphene kwimveliso egqityiweyo.
4. Ukukhutshwa
Inqanaba lokugqibela lokubumba ukuvuthela kukukhupha. Nje ukuba imveliso ipholile kwaye iqiniswe, ivuthela umatshini wokubumbaivula ukungunda ukukhulula imveliso egqityiweyo. Eli nqanaba kufuneka lenziwe ngononophelo ukuthintela ukonakalisa imveliso. Umatshini unokusebenzisa ingalo yerobhothi okanye iphini yokukhupha ukuncedisa ekususeni indawo ekubumbeni.
Emva kokukhutshwa, imveliso inokufuneka ihambe kwamanye amanyathelo okucubungula, njengokulungisa okanye ukuhlolwa, ngaphambi kokuba ipakishwe kwaye ithunyelwe. Ukusebenza kwenqanaba le-ejection kunokuba nempembelelo ebalulekileyo kumjikelezo wemveliso jikelele kwaye ngoko ke inxalenye ebalulekileyo yenkqubo yokubumba.
Ukubumba ukuvuthela yinkqubo yokuvelisa esebenzayo kunye neguquguqukayo exhomekeke ekusebenzeni ngokuchanekileyo komatshini wokubumba. Ngokuqonda izigaba ezine zokubunjwa kokuvuthela (i-extrusion, ukubunjwa, ukupholisa kunye nokukhupha), kunokwenzeka ukufumana ingqiqo ekuvelisweni kweemveliso zeplastiki ezingenanto. Inqanaba ngalinye lidlala indima ebalulekileyo ekuqinisekiseni umgangatho kunye nokuhambelana kwemveliso yokugqibela.
Njengoko imfuno yeemveliso zeplastiki ezikumgangatho ophezulu iqhubeka ukukhula kulo lonke uluhlu lwamashishini, inkqubela phambiliukubumba ukuvuthelaitekhnoloji kunye noomatshini banokunyusa ukusebenza kunye nobuchule benkqubo yokubumba. Nokuba ungumenzi, injineli, okanye unomdla nje kwihlabathi lemveliso yeplastiki, ukuqonda ezi zigaba kuya kukwenza nzulu ukuqonda kwakho ubunzima kunye nolutsha olusemva koomatshini bokubumba.
