Uma ufuna noma yiluphi uhlobo lomshini osebenza kuma-reels, ngokungangabazeki uzodinga i-decoiler noma i-decoiler.
Ukutshala imali emishinini emikhulu kuwumsebenzi odinga ukuthi ucabangele izici nezici eziningi. Ingabe udinga umshini ohlangabezana nezidingo zakho zamanje zokukhiqiza noma ufuna ukutshala kumakhono esizukulwane esilandelayo? Lena imibuzo abanikazi bezitolo abavame ukuzibuza yona lapho bethenga umshini wokwenza ama-roll. Kodwa-ke, kuncane ukunaka okuye kwakhokhelwa ocwaningweni ngama-unwinders.
Uma ufuna noma yimuphi umshini osebenza kuma-reels, khona-ke ngokungangabazeki uzodinga i-decoiler (noma i-decoiler njengoba ibizwa kanjalo ngezinye izikhathi). Noma ngabe unomugqa wokubumba, wokunyathela noma wokuhlikihla, uzodinga i-web decoiler yenqubo elandelayo; Ayikho enye indlela ngempela yokwenza. Ukuqinisekisa ukuthi i-decoiler yakho ihambisana nezidingo zesitolo sakho kanye nephrojekthi kubalulekile ekugcineni umshini wakho wokugaya usebenza, njengoba ngaphandle kwezinto ezibonakalayo umshini ngeke ukwazi ukusebenza.
Imboni ishintshe kakhulu kule minyaka engu-30 edlule, kodwa ama-unwinders abelokhu eklanyelwe ukuhlangabezana nokucaciswa komkhakha we-reel. Eminyakeni engamashumi amathathu edlule, i-diameter yangaphandle evamile (OD) yamakhoyili ensimbi yayingamayintshi angu-48. Njengoba umshini uba ngokwezifiso kakhulu futhi amaphrojekthi adinga izinketho ezahlukene, ikhoyili yensimbi yalungiswa ukuze ibe amayintshi angu-60 bese iba amayintshi angu-72. Namuhla, abakhiqizi ngezinye izikhathi basebenzisa ama-diameter angaphandle (ama-OD) angaphezu kwama-intshi angu-84. zikhona. Ikhoyili. Ngakho-ke, i-unwinder kufanele ilungiswe ukuze ivumelane nokushintsha kwe-diameter yangaphandle ye-reel.
Ama-Unwinders angatholakala kuyo yonke imboni yokwenza ama-roll. Imishini yanamuhla yokwenza umqulu inezici namandla amaningi kunangaphambili. Isibonelo, eminyakeni engu-30 edlule, imishini yokwenza ama-roll yayisebenza ngamafidi angama-50 ngomzuzu (FPM). Manje basebenza ngesivinini esingafika kumafithi angu-500 ngomzuzu. Lolu shintsho ekwakhiweni kwe-roll luphinde lwandise amandla nezinketho eziyisisekelo ze-decoiler. Ukumane ukhethe noma iyiphi i-unwinder ejwayelekile akwanele; udinga futhi ukukhetha i-unwinder efanele. Kunezici eziningi nezici okufanele uzicabangele ukuze uqinisekise ukuthi izidingo zesitolo sakho ziyahlangatshezwa.
Abakhiqizi bama-decoiler banikela ngezinketho ezahlukahlukene zokuthuthukisa inqubo yokwenza umqulu. Ama-unwinders anamuhla anesisindo esisuka ku-1,000 pounds. Ngaphezu kuka-60,000 lbs. Lapho ukhetha i-unwinder, cabangela izici ezilandelayo:
Kufanele futhi ucabangele ukuthi yiluphi uhlobo lwephrojekthi ozobe uyenza nokuthi yiziphi izinto ozozisebenzisa.
Konke kuncike ezingxenyeni ofuna ukuzisebenzisa kumshini wakho wokugaya, okuhlanganisa ukuthi umqulu upendwe kusengaphambili, uthayela, noma insimbi engagqwali. Zonke lezi zici zizonquma ukuthi yiziphi izici ze-unwinder ozidingayo.
Isibonelo, ama-decoiler ajwayelekile anohlangothi olulodwa, kodwa ukuba ne-decoiler ehlehliswayo kunganciphisa izikhathi zokulinda lapho kulayishwa impahla. Ngama-mandrel amabili, opharetha angalayisha umqulu wesibili emshinini, olungele ukucubungula lapho kudingeka. Lokhu kuwusizo ikakhulukazi ezimeni lapho opharetha kufanele ashintshe ama-spools njalo.
Abakhiqizi ngokuvamile abaqapheli ukuthi ama-unwinders angaba usizo kangakanani baze babone ukuthi, kuye ngosayizi we-roll, bangenza izinguquko eziyisithupha kuya kweziyisishiyagalombili noma ngaphezulu ngosuku. Uma nje umqulu wesibili usulungile futhi ulindile emshinini, asikho isidingo sokusebenzisa i-forklift noma i-crane ukulayisha umqulu uma umqulu wokuqala ususetshenzisiwe. Ama-Unwinders adlala indima ebalulekile ezinqubweni zokwakhiwa kwamakhoyili, ikakhulukazi ekukhiqizeni ivolumu ephezulu lapho umshini ungenza izingxenye phakathi noshintsho lwamahora ayisishiyagalombili.
Lapho utshala imali ku-decoiler, kubalulekile ukuqonda izici zakho zamanje namandla. Kodwa-ke, kubalulekile futhi ukucabangela ukusetshenziswa kwesikhathi esizayo komshini kanye namaphrojekthi esikhathi esizayo okungenzeka ahilela umshini wokwenza umqulu. Lezi yizo zonke izici ezidinga ukucatshangelwa ngokufanele futhi zingakusiza ngempela ukuthi ukhethe i-unwinder efanele.
Izinqola zamakhoyili zisiza ukulayisha amakhoyili kuma-mandrels ngaphandle kokulinda i-crane noma i-forklift ukuthi iqedele ukusebenza.
Ukukhetha usayizi omkhulu we-arbor kusho ukuthi ungasebenzisa ama-spools amancane emshinini. Ngakho, uma ukhetha 24 amayintshi. Spindle, ungakwazi ukugijima into encane. Uma ufuna ukugxuma ama-intshi angu-36. inketho, khona-ke udinga ukutshala imali ku-unwinder enkulu. Kubalulekile ukubheka amathuba esikhathi esizayo.
Njengoba ama-reel eba makhulu futhi esindayo, ukuphepha kuba yinto ekhathaza kakhulu phansi esitolo. Ama-Unwinder anezingxenye ezinkulu, ezihamba ngokushesha, ngakho-ke opharetha kufanele baqeqeshwe ekusebenzeni komshini kanye nezilungiselelo ezifanele.
Namuhla, izisindo ze-roll zisukela ku-33 kuya ku-250 kilograms per inch square, futhi ama-unwinders ashintshiwe ukuze ahlangabezane nezidingo zamandla esivuno zama-roll. Ama-reel asindayo adala ukukhathazeka okukhulu kokuphepha, ikakhulukazi lapho usikwa amabhande. Umshini ufakwe izingalo zokucindezela kanye namarola ebhafa ukuze kuqinisekiswe ukuthi iwebhu ikhululeka kuphela lapho kudingeka. Umshini ungase futhi uhlanganise idrayivu yokuphakelayo kanye nesisekelo se-sideshift ukuze usize phakathi nendawo umqulu wenqubo elandelayo.
Njengoba ama-spools eba nzima, kuba nzima kakhulu ukuqaqa i-mandrel ngesandla. Ama-mandrels okwandisa ama-hydraulic namandla okuzungezisa ngokuvamile ayadingeka njengoba izitolo zihambisa opharetha ukusuka endaweni yokuphumula kuya kwezinye izindawo zesitolo ngezizathu zokuphepha. Ama-absorber othusayo angengezwa ukuze kuncishiswe i-unwinder misrotation.
Ngokuya ngenqubo nesivinini, izici ezengeziwe zokuphepha zingadingeka. Lezi zici zifaka izibambi zamaroli ezibheke ngaphandle ukuze zivikele amaroli ukuthi angawi, amasistimu okulawula ububanzi beroli elingaphandle nesivinini sokuzungezisa, namasistimu okubhuleka ahlukile njengamabhuleki apholisa amanzi olayini bokukhiqiza abasebenza ngesivinini esiphezulu. Lokhu kubalulekile ukuqinisekisa ukuthi lapho inqubo yokwenza umqulu iyeka, i-unwinder nayo iyama.
Uma usebenza ngezinto ezinemibala ehlukene, ama-decoilers akhethekile anama-mandrel amahlanu ayatholakala. Lokhu kusho ukuthi ungakwazi ukufaka imiqulu emihlanu ehlukene emshinini ngesikhathi esisodwa. Ama-opharetha angakhiqiza amakhulu ezingxenye ngombala owodwa bese eshintshela kumbala wesibili ngaphandle kokumosha isikhathi ngokukhipha ama-spools nokushintsha.
Esinye isici inqola roll esiza ekulayisheni umqulu phezu mandrel. Lokhu kuqinisekisa ukuthi opharetha akudingeki balinde i-crane noma i-forklift ukuze ilayishe.
Kubalulekile ukuthatha isikhathi ukuhlola izinketho ezahlukene ze-unwinder. Ngama-mandrels alungisekayo ukuze afake ama-rolls angaphakathi ahlukene kanye nosayizi abahlukene bamapuleti asekela ama-roll, kunezici eziningi okufanele zicatshangelwe ukuze uthole ukulingana okulungile. Ukufaka kuhlu izici zamanje nezinamandla kuzokusiza ukuthi unqume izici ozidingayo.
Njenganoma yimuphi omunye umshini, umshini wokubumba unenzuzo kuphela lapho usebenza. Ukukhetha i-decoiler efanele ukuze ihambisane nezidingo zesitolo sakho zamanje nezesikhathi esizayo kuzosiza umshini wakho wokwenza ama-roll usebenze ngokuphumelelayo nangokuphepha.
