Yintoni umatshini osetyenziswa kwi-extrusion

I-Extrusion yinkqubo yokuvelisa ebandakanya ukugqithiswa kwezinto ngokufa ukwenza into eneprofayili eqingqiweyo yecandelo. Ubuchwephesha busetyenziswa kumashishini amaninzi aquka iiplastiki, isinyithi, ukutya kunye namayeza. Oomatshini abasetyenziselwa inkqubo yokukhupha i-extrusion yenzelwe ngokukodwa ukuhlangabezana neemfuno ezizodwa zezinto ezikhutshiweyo ukuze kuqinisekiswe ukusebenza kakuhle kunye nokuchaneka. Kweli nqaku, siza kujonga kwiindidi ezahlukeneyo zoomatshini abasetyenziswa kwinkqubo ye-extrusion, amacandelo abo, kunye nendlela abasebenza ngayo.

1. Isikruru Esinye Extruder

I-screw extruder enye lolona hlobo luqhelekileyo lwe-extruder. Iquka isikrufu se-helical esijikelezayo kwi-cylindrical barrel. Izinto eziphathekayo zityiswa kwi-hopper apho ifudunyezwa kwaye inyibilika njengoko ihamba ecaleni kwesikrufu. Uyilo lwe-screw luvumela ukuba izinto zixutywe, zinyibilike kwaye zimpompe kwintloko yokufa. I-screw extruders enye iyaguquguquka kakhulu kwaye ingasetyenziselwa uluhlu olubanzi lwezixhobo, kubandakanya i-thermoplastics kunye nezinye i-thermosets.

2. I-Twin Screw Extruder

I-twin-screw extruders inezikrufu ezibini ezidibanisayo ezijikeleza kwicala elinye okanye elichaseneyo. Olu luyilo luvumela ukuxubana okungcono kunye nokudibanisa kunye nokulungelelaniswa kwezicelo ezifuna iqondo eliphezulu le-homogeneity. I-twin-screw extruders idla ngokusetyenziswa kwimveliso yokutya, amayeza kunye nezinto eziphambili zepolymer. I-twin-screw extruders inokuphinda isebenze uluhlu olubanzi lwezixhobo, kubandakanya izinto ezingevani nobushushu.

3. IPlunger Extruder

I-Plunger extruders, ekwabizwa ngokuba yi-piston extruders, isebenzisa iplunger ephindaphindayo ukutyhala izinto ngokufa. Olu hlobo lwe-extruder luqhele ukusetyenziselwa izinto ekunzima ukusetyenzwa ngazo ngee-screw extruders, ezifana neekeramics kunye neentsimbi ezithile. I-Plunger extruders inokufikelela kuxinzelelo oluphezulu kakhulu kwaye ke ngoko ifanelekile kwizicelo ezifuna ingxinano ephezulu kunye ne-extrudates yamandla.

4. I-extruders yamaphepha

I-extruders ye-Sheet ngoomatshini abakhethekileyo bokuvelisa ama-flat sheets. Ngokuqhelekileyo basebenzisa indibaniselwano yesikruru esinye okanye iwele kunye ne-die ukuze bakhuphe imathiriyeli kwiphepha. Iphepha elikhutshiweyo linokupholisa kwaye linqunywe ngobukhulu obufanelekileyo kwiinkqubo ezahlukeneyo, kubandakanywa ukupakishwa, ukwakhiwa kunye neengxenye zemoto.

5.evuthelwa ifilimu extruder

Ifilimu evuthelweyo extruder yinkqubo ekhethekileyo esetyenziselwa ukwenza iifilimu zeplastiki. Kule nkqubo, iplastiki etyhidiweyo ikhutshelwa ngokufa kwesetyhula ize yandiswe yenze amaqamza. Amaqamza aphole kwaye acutheke ukwenza ifilimu ecaba. I-extruders yefilimu evuthelweyo isetyenziswa ngokubanzi kwishishini lokupakisha ukuvelisa iingxowa, iphepha lokusonga kunye nezinye izinto zokupakisha eziguquguqukayo.

Makhe sibonise inkampani yethuI-LQ 55 Umatshini ovuthela kabini wefilimu edibeneyo yokudibanisa ifilimu Umthengisi (ububanzi befilimu 800MM)

I-extruder iqulathe amacandelo amaninzi aphambili asebenza kunye ukuqinisekisa ukusetyenzwa ngempumelelo kwemathiriyeli:

I-Hopper: I-hopper kulapho impahla ekrwada ilayishwa kumatshini. Yenzelwe ukondla izinto eziluhlaza ngokuqhubekayo kwi-extruder.

Screw: Isikrufu yintliziyo ye-extruder. Inoxanduva lokuhambisa, ukunyibilika kunye nokuxuba izinto eziluhlaza njengoko zidlula kwi-barrel.

Umphanda: Umphanda liqokobhe lecylindrical eliqulethe isikrufu. I-barrel iqulethe izinto zokufudumeza zokunyibilika kwezinto kwaye inokuba neendawo zokupholisa zokulawula ubushushu.

Yifa: Idayizi licandelo elibumba imathiriyeli ekhutshiweyo kwimilo efunekayo. Ukufa kunokwenziwa ngokwezifiso ukwenza iimilo ezahlukeneyo zezinto ezifana nombhobho, iphepha okanye ifilimu.

Inkqubo yokupholisa: Emva kokuba i-material ishiya ifa, idla ngokufuna ukupholiswa ukuze igcine imilo yayo. Iinkqubo zokupholisa zingabandakanya ukuhlamba kwamanzi, ukupholisa umoya, okanye ukupholisa imiqulu, kuxhomekeke kwisicelo.

Iinkqubo zokusika: Kwezinye izicelo, izinto ezikhutshiweyo zinokufuna ukunqunyulwa ubude obuthile. Iinkqubo zokusika zinokudibaniswa kumgca we-extrusion ukwenza ngokuzenzekelayo le nkqubo.

Inkqubo ye-extrusion iqala ngokulayisha izinto eziluhlaza kwi-hopper. Impahla ekrwada ke ifakwe emgqomeni apho ithi ifudunyezwe kwaye inyibilikiswe njengoko ihamba ecaleni kwesikrufu. I-screw yenzelwe ukuxuba ngokufanelekileyo imathiriyeli ekrwada kwaye uyipompe kwi-die. Emva kokuba izinto zifikelele kwi-die, zinyanzeliswa ngokuvula ukuba zenze imilo efunekayo.

Emva kokuba i-extrudate ishiya idayizi, iyaphola kwaye iqine. Ngokuxhomekeke kuhlobo lwe-extruder kunye nezinto ezisetyenzisiweyo, amanye amanyathelo anokufuneka enziwe, njengokusika, ukujija okanye ukuqhubela phambili.

I-Extrusion yinkqubo yokuvelisa ebalulekileyo exhomekeke kwizixhobo ezikhethekileyo ukuvelisa iimveliso ezahlukeneyo. Ukusuka kwi-screw enye kunye ne-twin-screw extruders ukuya kwi-plunger extruders kunye noomatshini befilimu abavuthelweyo, uhlobo ngalunye lwe-extruder lunenjongo ekhethekileyo kwishishini. Ukuqonda amacandelo kunye nemisebenzi yala matshini kubalulekile ekuphuculeni inkqubo ye-extrusion kunye nokufezekisa iziphumo eziphezulu. Njengoko itekhnoloji iqhubeka nokuhambela phambili, ishishini le-extrusion kungenzeka libone izinto ezintsha eziya kwandisa ukusebenza kakuhle kunye nokwandisa amathuba okulungiswa kwezinto.
