Isilinda esivulekileyo esecaleni yokundla

I-hopper yokutya ecaleni luyilo olukhethekileyo lwee-screw extruders, ebonisa ukuvuleka okunye okanye ngaphezulu eludongeni lomgqomo ovumela izikongezo eziqinileyo okanye ezinamanzi ukuba ziziswe kwi-polymer etyhidiweyo ngexesha lenkqubo yokukhutshwa. .. Olu uyilo luphucula ukuguquguquka kokongezwa kwezinto kwaye lwenza ukuba uluhlu olubanzi lwemisebenzi yokulungisa. Indawo yokuvulwa kokutya kufuneka ilungiswe ngokusekwe kwiipropathi zezixhobo kunye neemfuno zenkqubo; zihlala zibekwe kwindawo yoxinzelelo lwesikrufu okanye kwindawo yokumitha. Ubungakanani bokuvuleka kufuneka buchazwe ngokwenqanaba lokuhamba kwesongezo kunye ne-viscosity yepolymer enyibilikayo, ngelixa uqinisekisa ukutywinwa okuqinileyo kwizivuleko ukuthintela ukuvuza kunye nokugcina ukuhambelana kobushushu phakathi kwesongezo kunye nepoly etyhidweyo ukunqanda iindawo zobushushu.

Ukuvula umphandi womatshini

Uqwalaselo lwe-barrel evulekileyo luyilo lomgqomo okhethekileyo wee-screw extruders ezibonisa ukuvulwa kwindawo ethile umgqomo, ngokuchaseneyo noyilo lwe-barrel evaliweyo. Oku kuvulwa kuhlala kusetyenziselwa ukondla izinto, ukuvutha, okanye ukuphambukiswa kwezinto ezisemacaleni. Kuxhomekeke kwindawo kunye nomsebenzi wokuvula, uqwalaselo lwemigca evulekileyo lunokuhlelwa ngolu hlobo lulandelayo: Ukuvulwa kubonelelwa kwicala lomgqomo, ikakhulu ukuphuma. Oku kususa ngokufanelekileyo izinto eziguqukayo, ukufuma, kunye nezinye iigesi kwizinto ezityhidiweyo, ngaloo ndlela kuphucula umgangatho wemveliso. -Ukuvula umgqomo wokugqibela: Ukuvulwa kubonelelwa kwenye okanye zombini iziphelo zomgqomo, okuvumela ukutya kwezinto okanye ukungenisa ukutya okusemacaleni. Olu qwalaselo luhlala lusetyenziswa kwizicelo ezizodwa zokuqhuba. - Ngaphezulu kwemimoya yendalo okanye i-vacuum vents, kuyimfuneko ngokubanzi ukufaka "ibhloko yokuvimba izinto" efanelekileyo ngaphakathi kokuvulwa ukunciphisa ukuhamba ngasemva.

Isiqendu

Iyunithi ye-90 ° ye-chear iqulethe iidiski ezintlanu ze-chear ezilungiselelwe kulungelelwaniso olugqithisileyo kunye ne-180 ° angular offset. Ngenxa yokuba ayinakho ukuhambisa phambili kunye nokubuyela umva, ibizwa ngokuba "yiyunithi yokucheba engathathi hlangothi." Ibonisa ukusasazeka okunamandla kunye nokuhambisa amandla okuxuba, kunye nenqanaba elithile lokuguqula amandla, kwaye kunokwakha uxinzelelo ukusa kwinqanaba elithile. Inceda ukulawula inqanaba lokugcwalisa izinto kunye nexesha lokuhlala, kwaye isetyenziswa ngaphezulu kwamacandelo okuvela kwendalo kunye namacandelo okuvela.

Ishishini elincinci neliPhakathi

Izinto ze-SME zizinto zokuxuba i-hybrid ezibonisa ii-grooves ezininzi ezibuyela umva ezibuyela umva kumatshini kwi-forward-con. Iziqalelo. Zihlala zisetyenziswa ngokudibeneyo nezinto zokuxhathisa; ngexesha lokuhambisa izinto, ii-grooves ezinzulu kwiinqwelomoya zesikrufu zibangela ukunyibilika umva, ngaloo ndlela ziphucule ukusasazwa. Umgaqo wokukhetha: Ezi zinto ziqeshwe ngokubanzi kummandla wokunyibilika wee-screw extruders.

Ukufaka isiqalo

Ukutsala izinto, ekwabizwa ngokuba zizinto ezimile okwe-S, zihlala zisetyenziswa kwizibini-ukutshintsha phambili kunye nokubuyela umva kwisikrufu. Ziphucula ngokufanelekileyo ukukwazi ukutshintshiselana ngezikhundla ezinxulumene. Izinto zolulela ezimile okwe-S zihlala ziqeshwa kwindawo yeplastiki yeplastiki eguqulweyo, apho zivelisa ukucheba okuthantayo kwaye ziqinisekise ukuxubana okungakumbi okufanayo.
