Ukuhlaziywa okuqondile kwemboni yemishini yokuthutha yaseChina, amabhizinisi amaningi anezinga elithile lokubandlululwa, okuthiwa uhlelo olulodwa lokusekela.Njengamanje, imakethe yaseChina, nakuba ukuvela kwenani lezinzuzo ezengeziwe zendikimba eyinhloko, ucwaningo lwalo oluqinile lwezobuchwepheshe kanye namakhono okuthuthukiswa, imikhiqizo yemishini yokudlulisa ephezulu kanye nemodi yokuphatha ethuthukisiwe phambili ekuthuthukiseni imboni futhi ibe ukuthuthukiswa kwezimakethe zamazwe omhlaba Ekuqaleni kwendikimba eyinhloko;kodwa okungeke kugwenywe ukuthi izinkampani eziningi zempahla yokuthutha azikwazi ukuqhathaniswa namakhono azo okucwaninga nokuthuthukisa ubuchwepheshe obuqhathaniswayo noma amakhono okuthuthukisa umkhiqizo.

Ku-conveyor yebhande, i-idler isetshenziselwa ukusekela ibhande lokuthutha kanye nempahla, futhi ibhande lokudlulisa alidluli umkhawulo.Inani lamarola okusetshenziswa okuvamile kokuthutha ibhande, ukusebenza kahle, izindleko zokunakekela, ukusetshenziswa kwamandla, izintengo zomshini zinomthelela obalulekile.Ngakho-ke, uma isikhala se-roller singaba umklamo nokuhleleka okunengqondo, akugcini nje ukunciphisa intengo yomshini, izindleko zokusebenza nokugcinwa kwezindleko, kodwa futhi kunganciphisa ngempumelelo ukuphambuka kwebhande lokudlulisa, ukugcinwa kokusebenza okujwayelekile kwemishini yokuthutha.

Ibanga eliphakathi kwamabhande asekhaya ngokuvamile linqunywa kusukela kudatha ye-empirical, noma isikhala esincane samarola sibalwa ngokucindezela okuncane kwebhande lokudlulisela.I-China okwamanje isekelwe ekucindezelekeni okuncane kwerola ukuze kunqunywe isikhala serola.Okokuqala, inani elincane lengcindezi yesigaba somthwalo othwalayo kanye nesigaba sokuthwala sibalwa ngokulandelana, futhi inani eliphezulu lethiyori lingabalwa ngokubala ibanga phakathi kwerola yenkampani yenethiwekhi kanye ne-idler ebuyayo.Isikhala samarola singanqunywa ngokusekelwe kumanani abaliwe futhi kucatshangelwa izici ezihlukahlukene ezingokoqobo.Isimiso esiyisisekelo sisekelwe esigabeni esithwalayo noma iphuzu eliphansi lokungezwani kwebhande le-conveyor, ukucacisa isikhala se-roller, ubude bomthumeli, ngokulandelana, kusetshenziswa isikhala se-roller efanayo.Nakuba lokhu kungenza kube lula ukuklama kanye nenqubo yokukhiqiza, kodwa hhayi ngokusho kwebhande lokudlulisa ngobude besithumeli ku-tension kanye ne-roller yamandla, okunengqondo ukunquma isikhala se-roller.

Ngokuba isithuthi sebanga elifushane sinomphumela omncane, kodwa ekuthuthweni okude kwe-conveyor enkulu yebhande elitshekile, kuzokwandisa kakhulu inani lama-roller, ukuze okokusebenza kubize kakhulu, ukumelana nokugijima, ukusetshenziswa kwamandla, izindleko zokunakekelwa kuzoba ukwanda okukhulu. , Ngakho-ke akunangqondo.Ucwaningo lokuhlola lwangaphandle lubonise ukuthi ukumelana nokuzikhethela kwe-roller kanye nokumelana nokucindezelwa kwebhande lokuthutha kubalele ku-50% -85% wokumelana okuyinhloko, isilinganiso esingu-70%.Ngakho-ke, ukuthuthukisa ukunemba kwe-roller kanye nokusebenza kwebhande lokuhambisa, kunganciphisa ngempumelelo ukumelana nokugijima.Kule minyaka eyishumi edlule, ukwakheka kwe-roller kuyaphuma.Ikakhulukazi, ukusetshenziswa kwama-bearings akhethekile okusebenza okuphezulu kanye nezimpawu zokunemba okuphezulu, ukunciphisa ngokuphumelelayo ukujikeleza kokumelana ne-roller.

I-conveyor yebhande ilokhu ishintsha kubo bonke ubude bezokuthutha.Isikhala se-roller esinengqondo, singahlangabezana ngokuphumelelayo nomthamo wokuthwala ama-roller, sandise impilo yesevisi yemishini.Ngaphansi kwemibandela yezidingo zebhande le-conveyor sag, ngokusho kobukhulu bokushuba kwembobo yesihlahla, ukucacisa isikhala se-roller.Ekwakhiweni, isikhala serola ngasikhathi sinye ukuhlangabezana nemibandela embalwa:

(1)Umthamo wokuthwala amarola kanye nezidingo zempilo yesevisi;
(2)Ukuqinisekisa ukuthi ibhande lokudlulisa elinesagi efanele.Ngokomthamo wokuthwala i-roller kanye nempilo yesevisi ukuze kunqunywe isikhala se-roller, umthamo wokuthwala i-roller nempilo yesevisi, kuye ngezici zempahla, ubude bebhande lokudlulisa kanye nekhwalithi yempahla, isikhala sokungenzi lutho, isivinini sebhande, ububanzi be-roller, i-roller ama-bearings Kanye nezimo zokusebenza nezinye izici.
(3) Ngokusho kwebhande le-conveyor sag ukuze kutholwe isikhala se-roller, ukucwiliswa kwebhande le-roller kuncike esikhaleni se-roller, lapho ukushuba kwebhande lokudlulisela, ubude bebhande lokuhambisa, kanye nekhwalithi yempahla nezinye izici.
