Umugqa Wokukhiqiza we-Single Screw PET Sheet Co-extrusion

Egagasini lezimboni lokusetshenziswa kabanzi kwemikhiqizo yepulasitiki, izinto zephepha le-PET zithathe indawo ebalulekile ekupakisheni, kuma-elekthronikhi, kwezokwelapha nakweminye imikhakha ngezakhiwo zazo eziyinhloko njengokucaca okuphezulu, ukuqina okuhle kakhulu, kanye nokumelana nokugqwala kwamakhemikhali. umugqa wokukhipha ishidi lesilwane I-JWELL Machinery ngokusebenzisa ubuchwepheshe obusha isibe yisisombululo esihamba phambili sokukhiqiza amashidi asekhaya ngenxa yezinqubo ezithuthukisiwe, ukusebenza okuzinzile kanye nomthamo wokukhiqiza osebenza kahle kakhulu. Umugqa wokukhiqiza awuthuthukisi nje kuphela ukusebenza kahle okuphelele cishe ngo-30% uma kuqhathaniswa nemishini efanayo yasekhaya, kodwa futhi uyahambisana nokukhiqizwa kwezinto eziningi ezifana ne-PLA, i-APET, i-PETG kanye ne-CPET. Ngaphezu kwalokho, imikhiqizo ye-PET ingaphinde isetshenziswe, okuhambisana kakhulu nomqondo womnotho ojikelezayo kanye nokuvikelwa kwemvelo.

Izici Eziyinhloko zomugqa wokukhipha ishidi le-PET

Uhlelo Lokwenza Amakristalu, Ukususa Umswakama kanye Nokomisa

Uhlelo lokwelapha olunezigaba ezintathu, oluqukethe umgqomo wokwenza ikristalu, i-dehumidifier kanye nombhoshongo wokomisa, luvimbela ukuhlangana kwezinto zokusetshenziswa ngokusebenzisa ikristalu ngaphambi kokwenza ipulasitiki. Ngemuva kwalokho, ngemiphumela emibili yokumuncwa ngokomzimba yi-dehumidifier kanye nokuqhutshwa kokushisa embhoshongweni wokomisa, okuqukethwe komswakama kwezinto zokusetshenziswa kulawulwa ezingeni eliphansi kakhulu. Le nqubo ithuthukisa kakhulu ukufana kokuncibilika kwama-PET pellets, ibeka isisekelo esiqinile sokukhipha ipulasitiki okulandelayo kanye nokuqinisekisa ikhwalithi yamashidi.

Uhlelo Lokulawula Oluhlakaniphile lwe-PLC kanye ne-HMI

Ngokuxhumanisa phakathi kwe-PLC yezinga lezimboni (i-Programmable Logic Controller) kanye ne-HMI (i-Human-Machine Interface), ukulawula okunamandla kokubambisana kanye nempendulo yedatha yesikhathi sangempela kuyo yonke inqubo yokukhiqiza kuyatholakala.

● I-interface yokusebenza enembile nefushane ene-automation ephezulu.

● Ukutholwa okusheshayo kanye nokusabela ezinkingeni zokukhiqiza, okuqinisekisa ukusebenza okuzinzile nokusebenza kahle kuyo yonke inqubo.

Uhlelo Lokulawula Oluhlakaniphile lwe-PLC kanye ne-HMI

Njengemishini yokwakha eyinhloko, le extruder yenzelwe ngqo amashidi e-PET asezingeni eliphezulu:

● Izinzuzo Zokusebenza: Uma usebenzisa izinto zokusetshenziswa ze-virgin pellet, ikhiqiza amashidi anokukhanya okuphezulu, i-viscosity ephezulu, kanye nezakhiwo ezinhle kakhulu zokuthambekela, ehlangabezana nezidingo eziqinile zemikhiqizo emikhulu eyenziwe nge-thermostat.

● Imininingwane Yokukhiqiza: Ingakhiqiza imikhiqizo enobubanzi bokujiya obungu-0.08-2mm. Umphumela Omkhulu womugqa wokukhiqiza wonke ungafinyelela ku-1,200 kg/h kanye nemigqa ye-co-extrusion enesivinini esikhulu enama-extruder angu-2-3: 1,000-3,000 kg/h, evumelana nezimo nezidingo ezahlukahlukene.

Inqubo Yokuhlanganiswa Kwesikulufo Nemigqomo

● Ukuqamba Okusha Kwesakhiwo: Isikulufu senziwe kusetshenziswa ubuchwepheshe obuhlanganisiwe bezinto eziningi. Ngemva kokwelashwa nge-nitriding, quenching kanye tempering, sinobulukhuni obuphezulu bendawo kanye nokumelana okuhle kakhulu kokuhuzuka. Umklamo wentambo ekhethekile wenza ngcono ukusebenza kahle kokudlulisa izinto, ukuqinisekisa ukuthi ipulasitiki iyafana futhi ukuncibilika kwayo kuncibilike kahle.

● Umklamo Owonga Amandla: Umgqomo ufakwe ama-heater asebenzisa i-infrared ekude, asebenzisa amandla amaningi kunokushisa okumelana nokumelana okuvamile. Anikeza ukukhuphuka kwezinga lokushisa okusheshayo kanye nokusatshalaliswa kwensimu yokushisa okufanayo.

Uhlobo lwesikhunta se-T

Isikhunta sohlobo lwe-T, esinomklamo wokugijima wohlobo lwe-hanger kanye nensimbi yesikhunta yekhwalithi ephezulu siqinisekisa impilo yenkonzo ende futhi senza kube lula ukukhiqizwa kwamashidi anembile nasezingeni eliphezulu.

Ikhalenda lama-roller amathathu lohlobo lwe-J

● Isakhiwo Semishini: Ukwakheka kohlobo lwe-]-kwenza ngcono ibhalansi yamandla ohlelweni lwe-roller. Ububanzi bokusebenza kwama-roller bufinyelela ku-1,600 mm, kanti izinga lokushelela nokuhlanzeka kwe-roller yesibuko lingu-≤0.016 um.

● Ukulawula Idrayivu: Ifakwe uhlelo lokushayela lwe-servo motor, inesivinini sokuphendula esisheshayo kanye nokunemba kokulawula isivinini esijikelezayo okuphezulu, okuvumela ukulawula okunembile kakhulu kokufana kobukhulu beshidi.

Uhlelo Lokulinganisa Ubukhulu Be-X-ray Ku-inthanethi

Igeyiji yobukhulu be-X-ray ehlanganisiwe enembile kakhulu yenza ukuskena kanye nokuqapha ukujiya kweshidi ngesikhathi sangempela. Ngemva kokuba idatha ihlaziywe yi-algorithm, ibuyiselwa emuva ku-extruder kanye nohlelo lwe-three-roll ukuqinisekisa ukuthi ukushintshashintsha kobukhulu beshidi kulawulwa ngaphakathi kobubanzi obuncane.

Uhlelo Lokugoqa Isikhungo Seziteshi Eziningi

Isebenzisa ukugoqa okuqhubekayo kweziteshi eziningi, isekela imisebenzi yokugoqa okuqhubekayo enamandla amakhulu okugoqa kanye nokusebenza kahle okuphezulu.

Izinzuzo Zomkhiqizo Nezicelo

● Isisindo Esiphansi: Njengoba incane kakhulu, ilula ngaphezu kuka-50% kunengilazi ngobuningi obufanayo, okunciphisa kakhulu izindleko zokuhamba kanye nokusetshenziswa kwamandla.

● Iphephile Futhi Ayinabo ubuthi: Iqinisekisiwe ukuthi ithintana nokudla, ayinazo izinto eziyingozi futhi ingathintana ngqo nokudla kanye nemithi.

● Ukuphinda kusetshenziswe: Kungasetshenziswa kabusha ngo-100%, okuvumela ukusetshenziswa okujikelezayo ngokusebenzisa kabusha ngokomzimba (ukuncibilikisa kanye nokufaka i-pelletizing) noma ukuphinda kusetshenziswe amakhemikhali (ukususa i-polymerization kuma-monomers), okuhambisana nemikhuba yentuthuko esimeme.

● Izinkambu Zokusebenzisa: Kusetshenziswa kabanzi ezimbonini ezahlukahlukene njengokupakisha ukudla, ukupakisha kwezokwelapha, izidingo zansuku zonke, ukupakisha kwezimonyo, ifilimu yokuvikela imikhiqizo kagesi, njll.
