Li-uncoilers li sebelisoa haholo indastering ea rolling.Mechini ea kajeno ea ho etsa roll e na le likarolo le mesebetsi e mengata ho feta ea pele ho eona.Mohlala, lilemong tse 30 tse fetileng, lebelo la ts'ebetso ea leloala la roll e ne e le maoto a 50 ka motsotso (FPM).Hona joale ba ka matha ho fihla ho 500 FPM.Phetoho ena ea tlhahiso ea ho etsa roll e boetse e ntlafalitse bokhoni le mefuta ea mantlha ea likhetho tsa li-decoiler.Ha hoa lekana ho khetha decoiler efe kapa efe e tloaelehileng.Lintlha tse ngata le mesebetsi e lokelang ho nahanoa ho netefatsa hore litlhoko tsa workshop lia khotsofatsoa.
Moetsi oa li-decoiler o fana ka likhetho tse fapaneng ho netefatsa hore mokhoa oa ho etsa roll o ka ntlafatsoa.Decoiler ea kajeno e boima ba liponto tse 1,000.Ho feta liponto tse 60,000.Ha u khetha decoiler, ka kopo hopola lintlha tse latelang:
Hape u lokela ho nahana ka mofuta oa morero oo u tla be u sebetsa ho oona le lisebelisoa tseo u tla li sebelisa.
Tsohle li itšetlehile ka seo u batlang ho se tsamaisa holim'a leloala le roalang, ho kenyelletsa le hore na coil ke tšepe e entsoeng pele, e entsoeng ka galvanized kapa e sa hloekang.Litlhaloso tsena li tla khetholla hore na u hloka likarolo life tsa decoiler.
Ka mohlala, "decoiler" e tloaelehileng ke "decoiler" e nang le nako e le 'ngoe, empa ho ba le "decoiler" e nang le mahlakore a mabeli ho ka fokotsa nako ea ho leta bakeng sa ho tšoara thepa.Ka li-spindle tse peli, opareitara e ka kenya khoele ea bobeli mochining ebe e e sebetsa neng kapa neng ha ho hlokahala.Sena se bohlokoa haholo ha opareitara e lula e hloka ho khutlisa khoele.
Hangata bahlahisi ha ba lemohe ts'ebetso ea "decoiler" ho fihlela ba hlokomela hore decoiler e ka etsa ts'ebetso ea ho nchafatsa tse tšeletseng ho isa ho tse robeli kapa ho feta ka letsatsi.Ka mor'a ho lokisa coil ea bobeli mochineng le ho emela mochine, ha ho hlokahale hore u jare coil ea pele ka forklift kapa crane hang-hang.Decoiler e bapala karolo ea bohlokoa tikolohong ea ho theha moqolo, haholo tlhahisong ea bongata, moo mochini o ka hlokang lihora tse robeli ho etsa likarolo.
Ha u tsetela ho decoiler, ho bohlokoa ho utloisisa litlhaloso le likarolo tsa hajoale.Leha ho le joalo, hape ke habohlokoa ho nahana ka tšebeliso ea nako e tlang ea mochine le hore na merero ea ka moso e ka ’nang ea e-ba efe leloaleng la ho thetheha.Tsena ke lintlha tsohle tse hlokang ho nahanoa ka nepo, 'me li hlile li thusa ho tseba decoiler e nepahetseng.
Koloi ea coil e thusa ho kenya coil holim'a mandrel ntle le ho emela hore crane kapa forklift e phethe.
Ho khetha mandrel e kholoanyane ho bolela hore o ka tsamaisa khoele e nyane mochining.Ka hona, haeba u khetha 24 inches.Spindle, o ka etsa ts'ebetso efe kapa efe.Haeba u batla ho qhomela ho 36 inches.Khetho, joale o hloka ho tsetela ho decoiler e kholoanyane.Ho bohlokoa ho batla menyetla nakong e tlang.
Ha likhoele li ntse li hola le ho ba boima, polokeho ke eona bothata bo boholo ka har'a workshop.Decoiler e na le likarolo tse kholo, tse tsamaeang ka potlako, kahoo basebelisi ba tlameha ho koetlisoa ts'ebetsong ea mochini le litlhophiso tse nepahetseng.
Kajeno, li-coil li ka tloha ho 33 ho isa ho 250 kilograms ka square inch, 'me li-uncoilers li fetotsoe ho finyella litlhoko tsa matla a ho hlahisa li-coil.Likhoeli tse boima haholo li baka mathata a mangata a tšireletso, haholo-holo ha u khaola mabanta.Mochini o kenyelletsa letsoho la khatello le "buffer roller" ho netefatsa hore moqolo ha oa phutholoha ha ho hlokahala.Mochine o ka boela oa kenyelletsa mochine oa ho fepa pampiri le setsi sa ho fetola mahlakoreng ho thusa setsi sa marang-rang bakeng sa ts'ebetso e latelang.
Ha boima ba coil bo ntse bo eketseha, ho ba thata haholoanyane ho atolosa mandrel ka letsoho.Ha workshop e tlosa opareitara ho tloha ho decoiler ho ea libakeng tse ling tsa workshop ka mabaka a ts'ireletso, hangata li-spindle tse atolositsoeng ka metsi le matla a ho potoloha lia hlokahala.Ho ka eketsoa sesebelisoa sa ho ts'oha ho fokotsa ts'ebeliso e mpe ea ho potoloha ha decoiler.
Ho latela ts'ebetso le lebelo, likarolo tse ling tsa polokeho li ka hlokahala.Likarolo tsena li kenyelletsa sets'oants'o sa coil sa kantle ho thibela khola hore e se ke ea oa, mokhoa oa ho beha leihlo bakeng sa bophara ba coil kantle le RPM, le mekhoa e ikhethang ea mariki joalo ka mariki a pholileng ka metsi bakeng sa liphaephe tse mathang ka lebelo le phahameng.Tsena ke tsa bohlokoa haholo 'me li thusa ho netefatsa hore ha ts'ebetso ea ho roala e emisa, decoiler e boetse e emisa.
Haeba u sebetsa ka thepa ea mebala e mengata, u ka sebelisa decoiler e khethehileng e fanang ka mandrel a mahlano, e bolelang hore u ka beha li-coil tse hlano tse fapaneng mochine hang-hang.Motho ea sebetsang a ka etsa makholo a 'mala o le mong ebe o fetohela ho' mala oa bobeli ntle le ho qeta nako a laolla khoele le ho switjha.
Tšobotsi e 'ngoe ea koloi ea khoele ke hore e thusa ho kenya coil holim'a mandrel.Sena se etsa bonnete ba hore opareitara ha ea tlameha ho emela hore crane kapa forklift e kene.
Ho bohlokoa ho qeta nako u etsa lipatlisiso ka likhetho tse fapaneng tse fumanehang bakeng sa decoiler.Ka mandrel e fetolehang ho amohela li-coil tsa li-diameter tse fapaneng tse ka hare, le likhetho tse fapaneng tsa boholo bakeng sa mokokotlo oa mokokotlo, o hloka ho nahana ka lintlha tse ngata ho fumana ho lekana ho loketseng.Ho thathamisa litlhaloso tsa hajoale le tse ka bang teng ho tla u thusa ho tseba likarolo tse hlokahalang.
