Inkqubo yolawulo yomatshini weplastiki wepelletizing ibandakanya inkqubo yokufudumeza, inkqubo yokupholisa kunye nenkqubo yokulinganisa ipharamitha yenkqubo, ebandakanya ubukhulu becala izixhobo zombane, izixhobo kunye ne-actuator (okt ipaneli yokulawula kunye nedesika yokusebenza).Imisebenzi yayo ephambili yile: ukulawula nokulawula iinjini zokutsala zoomatshini abakhulu kunye nabancedisayo, ukuphuma kwesantya kunye namandla ngokuhambelana neemfuno zenkqubo, kunye nokwenza ukuba oomatshini abakhulu kunye nabancedisayo basebenze ngokubambisana;ukufumanisa nokulawula ubushushu, uxinzelelo kunye nokuhamba kweplastiki kwi-extruder;ukuqonda ulawulo okanye ulawulo oluzenzekelayo lweyunithi iyonke.
Ulawulo lombane lweyunithi ye-extrusion luqikelelwa ukuba lwahlulahlulwe lube ngamacandelo amabini amakhulu: ulawulo lothumelo kunye nolawulo lobushushu, ukufezekisa inkqubo ye-extrusion kubandakanya iqondo lobushushu, uxinzelelo, ukujikeleziswa kwesikrufu, ukupholisa isikrufu, ukupholisa umgqomo, ukupholisa imveliso kunye nolawulo lwedayamitha yangaphandle, ngokunjalo isantya sokutsala, umgca ngokucocekileyo kunye nokuqinisekisa ukuba ipleyiti yokuqokelela ucingo ukusuka engenanto ukuya kwipleyiti epheleleyo yoxinzelelo oluqhubekayo kulawulo lokuqokelela ucingo.
1. Extruder inginginya ulawulo lobushushu ngocingo kunye ukugquma intambo kunye sheathing iplastiki extrusion isekelwe iimpawu deformation thermoplastic, ukuze ibe kwimo flow viscous.Ukongeza kwiimfuno zokufudumeza yangaphandle Screw kunye emgqonyeni ukuya kwiplastiki ukunyibilika extrusion, kodwa kwakhona uthathele ingqalelo extrusion Screw yeplastiki xa ubushushu bayo, ngoko iqondo lobushushu umkhosi kufuneka kuthathelwe ingqalelo ukusuka iyonke, zombini ukuqwalasela. Isifudumezi-sifudumezi sivuleke kwaye sivalwe, kodwa kwakhona kuqwalaselwe imiba yokuphuphuma kobushushu ekrwadayo ukuze kupholiswe, ukuba neendawo zokupholisa ezisebenzayo.Kwaye kufuna ukuzimisela okuchanekileyo kunye nokufanelekileyo kwendawo yokulinganisa i-thermocouple kunye nendlela yokufakela, inokufundwa kwisixhobo sokulawula ubushushu ngokuchanekileyo sibonisa ubushushu bokwenene becandelo ngalinye lomkhosi.Kwakunye neemfuno zokuchaneka kwemitha yokulawula ubushushu kunye nenkqubo ngentsebenziswano elungileyo, ukuze uzinzo lokuguquguquka kwenkqubo yolawulo lobushushu yomkhosi wonke ukuze kufezekiswe iimfuno ezahlukeneyo zobushushu beplastiki.
2. Ukulawulwa koxinzelelo lwe-peal extruder ukwenzela ukubonakalisa ukugqithiswa kwentloko, isidingo sokubona ukugqithiswa kwentloko yoxinzelelo, kuba umatshini wasekhaya we-extrusion awunayo inzwa yoxinzelelo lwentloko, ngokuqhelekileyo umlinganiselo we-screw extrusion emva i-thrust endaweni yokulinganisa uxinzelelo lwentloko, itafile yomthwalo we-screw (i-ammeter okanye i-voltmeter) ingabonakalisa ngokuchanekileyo ubungakanani boxinzelelo lwe-extrusion.Ukuguquguquka koxinzelelo lwe-extrusion kukwayenye yezinto ezibalulekileyo ezibangela umgangatho ongazinzanga we-extrusion.Ukuguquguquka koxinzelelo lwe-extrusion kuhambelana ngokusondeleyo nokushisa kwe-extrusion, ukusetyenziswa kwezixhobo zokupholisa, ubude bexesha eliqhubekayo lokusebenza kunye nezinye izinto.Xa isenzeko esingaqhelekanga sisenzeka, singabandakanyi ngokukhawuleza, kufuneka siphinde silungelelanise imveliso kufuneka sibe sisigqibo sokuyeka, asikwazi nje ukuphepha ukwanda kwenkunkuma, ngakumbi kunokuthintela ukwenzeka kweengozi.Ngokubona ufundo lwegauge yoxinzelelo, unokwazi imeko yoxinzelelo lweplastiki kwi-extrusion, thatha ngokubanzi emva kokulawulwa kwe-alarm yexabiso lokutyhala.
