Umenzi ochwephesha woomatshini be-thermoforming.
Umgaqo we-Vacuum Forming Machine: Ukubumba i-vacuum kukwabizwa ngokuba yi-thermoplastic forming, Le nkqubo ibandakanya ukufudumeza kunye nokuthambisa amacwecwe e-thermoplastic (umzekelo, i-PVC, i-PET, i-PP) kunye nokusebenzisa impompo yokucoca ukuyibumba phezu kwe-molds, ukuvelisa izinto ezifana ne-vacuum-formed covers, i-blister tray, kunye ne-clamshell packaging.
Umatshini wokwenza i-vacuum uquka iindawo ezininzi ezifana nenkqubo yokuqinisa, inkqubo yokufudumeza, i-vacuum kunye nenkqubo yomoya ecinezelweyo kunye nokungunda.
Xa iphepha leplastiki libunjiwe, ishidi lizinzile kwisixhobo sokubambelela. Kwi-thermoforming yenjongo ngokubanzi kunye noomatshini be-thermoforming abadibeneyo basetyenziselwa ukuququzelela ukulungiswa kobukhulu obuhlukeneyo besixhobo sokudibanisa iphepha. Kwezinye iimeko, umatshini wonke wokubumba uxhotyiswe ngeseti yeefreyimu zokubethelela.
Inkqubo yokubamba kufuneka iphuculwe ngolawulo oluzenzekelayo ukuphumeza ukusebenza ngokukhawuleza, ngaloo ndlela iphucula umgangatho wenxalenye kunye nokusebenza kakuhle kwemveliso.
Iphepha le-Thermoplastic kunye nefilimu yenkqubo yokubumba i-vacuum, enye yeenkqubo eziphambili ze-sheet heat.Ubude bexesha kunye nokusebenza kakuhle kuxhomekeke kwizinto ezibandakanya ukuyila kwe-heater, inertia ye-radiation surface thermal, i-sheet-to-heater distance, i-coefficients yokufunxa izinto, kunye neempawu ze-thermophysical. Izifudumezi ezisetyenziswa ngokuqhelekileyo zizifudumezi zombane, ii-crystal emitters kunye nezifudumezi ze-infrared.
Inkqubo yokucoca iqulethe iimpompo zokufunxa, iitanki, iivalvu, imibhobho kunye ne-vacuum gauge, njl. njl., ehlala isetyenziswa kwi-vacuum eyenza uhlobo olwahlukileyo lwempompo yokucoca, i-vacuum yeempompo ezinjalo kufuneka ifikelele kwi-0.07 ~ 0.09 Mpa (520mmHg) okanye ngaphezulu. Itanki yokugcina igesi ngokuqhelekileyo yibhokisi yecylindrical edityaniswe ngeepleyiti zentsimbi ezincinci kwaye inombhoxo ophantsi. Umthamo wetanki yokugcina igesi kufuneka ubuncinci isiqingatha somthamo wegumbi elikhulu lokubumba. Umbhobho wokufunxa kufuneka uxhotyiswe ngeevalvu ezifanelekileyo ukulawula umthamo omxinwa wevacuum.
Amandla wempompo yempompo yokufunxa (ngokuqhelekileyo i-2-4 kW kwiinkqubo ezinkulu/zesantya esiphezulu) amiselwa bubungakanani besixhobo kunye neemfuno zemveliso. Imibhobho yokufunxa ifuna iivalvu ezichanekileyo zolawulo lokuhamba. Ubungakanani benkqubo yevacuum central ixhomekeke kwimveliso ethile kunye neemfuno zophuhliso lomzi-mveliso.
Inkqubo yomoya iquka iicompressors, iitanki zomoya, iivalve, kunye nemibhobho. Oomatshini bokubumba badla ngokufuna i-0.4-0.5 MPa yomoya oxinanisiweyo, obonelelwa nokuba ziicompressor zepiston ezidityanisiweyo okanye iicompressor ze-screw zezityalo ezisembindini. Unokusebenzisa icompressor enkulu yomoya we-screw yonke unikezelo lwesityalo.
Umoya oxinanisiweyo ukongeza kwinani elikhulu kufuneka lisetyenziswe ekwenzeni, kukho xa inxalenye yokubumba kwiimveliso zokuqala ngaphandle kokupholisa kunye nokuphathwa kwesakhelo sokubumba kunye nephepha eliqhubayo kunye nezinye iindawo zomatshini ezifana namandla okusebenza.
Ukuze kuphuculwe ukusebenza kakuhle kwemveliso, iimveliso zokwenza ivacuum zisoloko zifuneka ukuba zipholile phambi kokuba zidilizwe. Ngokufanelekileyo, iindawo zangaphakathi kunye nezangaphandle zamacandelo adibanisa ne-mold zipholile, kwaye kulungele ukusebenzisa i-molds kunye neentsimbi zokupholisa zangaphakathi. Kwizibungu ezingezizo zetsimbi, ezifana nemithi, i-plaster, i-glass fibers eqiniswe iiplastiki, i-epoxy resin kunye nezinye iimbumba, ngenxa yokuba akunakwenzeka ukusebenzisa ukupholisa kwamanzi, kunokutshintshwa kwi-air cooling, kwaye ifakwe kwinkungu yamanzi ukupholisa umphezulu wangaphandle we-vacuum forming parts.
Ukupholisa kwendalo kuvelisa iindawo ezithomalalisa uxinzelelo kunye noxhathiso oluphuculweyo lwempembelelo. Ngelixa ukupholisa kwamanzi kwandisa imveliso, kunokubangela uxinzelelo oluphezulu lwangaphakathi.
Ukubunjwa kubandakanya ukukhupha imveliso ekubumbeni, enokuba yi-concave okanye i-convex. Kwiimeko ezininzi, ukuchithwa kwe-thermal kubangela ukuba inxalenye ibambelele ngokuqinileyo kwi-mold. Ukunciphisa ke ngoko kuphunyezwa ngokufaka uxinzelelo lomoya olubuyela umva ngokusebenzisa amazibuko okucoca okanye amajelo omoya axinanisiweyo.
Ngokukodwa kwi-molds kunye ne-slope encinci yokukhululwa okanye kunye ne-concave molds, i-mold iphinda ikhululwe ngokusebenzisa indlela yokukhululwa ye-bumping okanye i-vibration, ngamanye amaxesha ngokufaka i-arhente yokukhululwa kwiphepha kunye ne-mold, okanye ngokutshiza umphezulu we-mold ngonyango lwe-Teflon.
Inkqubo yokulawula ngokubanzi ibandakanya ukwenziwa kwevacuum, ukugqiba kunye nezinye iinkqubo, kubandakanywa izixhobo, iimitha, imibhobho, iivalvu kunye nokulawula iiparamitha kunye neendlela zokuvuselela. Iindlela zokulawula ziyi-manual, ulawulo oluzenzekelayo lwe-electromechanical, ulawulo lwekhompyutha, njl.
