二、膠帶跑偏原因分析
膠帶跑偏是指輸送物料時，膠帶在物料的重量、驅動、zhichengdengzhuangzhimocalijudezuoyongxia，jiaodaipianlishusongjizhongxin，xiangliangceyidong。genjudaishishusongjijiegouhegongzuotedian，jiaodaipaopiandeyuanyinzhuyaoyouyixiajifangmian。
1．供料不正
采cai用yong電dian磁ci振zhen動dong給gei料liao機ji向xiang輸shu送song機ji供gong料liao時shi，下xia落luo物wu料liao不bu在zai膠jiao帶dai傳chuan送song方fang向xiang中zhong心xin線xian位wei置zhi，使shi膠jiao帶dai張zhang力li和he托tuo輥gun支zhi承cheng力li不bu平ping衡heng，產chan生sheng側ce向xiang推tui力li，在zai膠jiao帶dai運yun行xing時shi將jiang其qi推tui向xiang一yi邊bian而er跑pao偏pian。
2．膠帶接頭不正
膠(jiao)帶(dai)接(jie)頭(tou)一(yi)般(ban)采(cai)用(yong)硫(liu)化(hua)膠(jiao)接(jie)法(fa)和(he)機(ji)械(xie)聯(lian)接(jie)法(fa)，膠(jiao)帶(dai)接(jie)頭(tou)剖(pou)切(qie)成(cheng)對(dui)稱(cheng)階(jie)梯(ti)式(shi)，如(ru)果(guo)帶(dai)條(tiao)邊(bian)線(xian)斜(xie)割(ge)或(huo)斜(xie)接(jie)，在(zai)膠(jiao)帶(dai)兩(liang)端(duan)采(cai)用(yong)打(da)卡(ka)時(shi)，卡(ka)板(ban)接(jie)頭(tou)歪(wai)斜(xie)或(huo)鬆(song)緊(jin)不(bu)一(yi)致(zhi)，造(zao)成(cheng)膠(jiao)帶(dai)運(yun)轉(zhuan)時(shi)向(xiang)鬆(song)邊(bian)跑(pao)偏(pian)。
3．傳動滾筒與尾部滾筒不平行
這zhe種zhong情qing況kuang多duo發fa生sheng於yu尾wei部bu滾gun筒tong安an裝zhuang螺luo旋xuan張zhang緊jin裝zhuang置zhi的de帶dai式shi輸shu送song機ji上shang，調tiao整zheng膠jiao帶dai鬆song緊jin時shi，兩liang螺luo杆gan鬆song緊jin不bu一yi致zhi，使shi膠jiao帶dai兩liang邊bian的de張zhang緊jin力li不bu平ping衡heng，膠jiao帶dai在zai尾wei部bu滾gun筒tong上shang向xiang螺luo杆gan鬆song邊bian跑pao偏pian。
4．滾筒表麵黏有異物
驅動滾筒或改向滾筒表麵黏有異物，使滾筒直徑發生了不規則變化，哪邊滾筒直徑小，膠帶就向哪邊跑偏。
5．托輥組
托輥安裝不正或托輥組支架、機架損壞，軸承損壞、缺油等，造成局部托阻力增大，膠帶局部跑偏。
三、膠帶跑偏的調整
1．下料不正的調整
jiaodaiyunxingshi，kongzhuanshibupaopian，youfuzaishipaopian，shuominggeiliaojigongsongwuliaozaijiaodailiangbianfenbubujunyun，zhuangliaoloudoubuzheng。yingxiaozhengloudouweizhihuozailoudouzhongjiananzhuangdaoliaoban。gaibianluoliaojiaodu，yidadaosuishitiaozhengliaoliufangxiang，shijiaodailiangbianliaoliufenbujunyunyizhi，bimianjiaodaiyingongliaobuzhengfuzaishipaopian。
2．膠帶接頭不正的調整
膠jiao帶dai運yun行xing總zong向xiang一yi邊bian跑pao偏pian，最zui大da跑pao偏pian恰qia在zai接jie頭tou處chu，而er且qie跑pao偏pian位wei置zhi不bu固gu定ding，說shuo明ming膠jiao帶dai接jie頭tou不bu正zheng，應ying重zhong新xin校xiao正zheng膠jiao帶dai接jie頭tou或huo更geng換huan新xin接jie頭tou。當dang膠jiao帶dai邊bian緣yuan磨mo損sun嚴yan重zhong，使shi膠jiao帶dai兩liang邊bian拉la力li不bu一yi致zhi，膠jiao帶dai跑pao偏pian位wei置zhi不bu固gu定ding，應ying根gen據ju實shi際ji情qing況kuang修xiu補bu膠jiao帶dai或huo更geng換huan新xin膠jiao帶dai。
3．驅動滾筒與尾筒的調整
jiaodaizaijiweihuojitouchupaopian，yingxiaochutouweibuguntongdepingxingduwucha。lingwai，yinggenjuguntongshuipingcuandongqingkuang，xiaozhengqianhouguntongshuipinghuopingdengduwucha，guntongbiaomiannianyouyiwuhewuliaoshijishiqingli，jiaodaipaopianjiuzihuixiaoshi。
4．拉緊裝置的調整
膠jiao帶dai空kong載zai或huo重zhong載zai時shi向xiang一yi側ce跑pao動dong，說shuo明ming膠jiao帶dai兩liang側ce鬆song緊jin程cheng度du不bu一yi致zhi，應ying調tiao整zheng前qian後hou滾gun筒tong處chu的de絲si杆gan或huo配pei重zhong等deng拉la緊jin裝zhuang置zhi，如ru果guo膠jiao帶dai運yun轉zhuan左zuo右you跑pao偏pian無wu固gu定ding方fang向xiang，說shuo明ming膠jiao帶dai鬆song馳chi，應ying調tiao整zheng拉la緊jin裝zhuang置zhi，繃beng緊jin膠jiao帶dai，跑pao偏pian就jiu會hui消xiao失shi。
5．托輥組調整
(1)自zi動dong調tiao整zheng托tuo輥gun組zu安an裝zhuang利li用yong膠jiao帶dai跑pao偏pian時shi對dui托tuo輥gun組zu架jia摩mo擦ca力li不bu對dui稱cheng，產chan生sheng一yi個ge附fu加jia力li矩ju，使shi托tuo輥gun組zu架jia繞rao其qi垂chui直zhi軸zhou座zuo回hui轉zhuan一yi個ge角jiao度du，使shi膠jiao帶dai向xiang輸shu送song機ji中zhong心xin移yi動dong，從cong而er達da到dao自zi動dong糾jiu偏pian的de目mu的de。自zi動dong調tiao心xin托tuo輥gun組zu主zhu要yao用yong於yu長chang度du大da於yu50m的帶，承載段每隔10組托輥設置一組凋心托輥，非承載段每6-10組平行托輥設置一組下平行托輥。合理安裝自動調心托輥，可以起到自動調節帶跑偏的作用。
(2)槽(cao)形(xing)托(tuo)輥(gun)調(tiao)整(zheng)把(ba)槽(cao)形(xing)托(tuo)輥(gun)調(tiao)正(zheng)，帶(dai)條(tiao)就(jiu)可(ke)以(yi)正(zheng)常(chang)運(yun)行(xing)。但(dan)安(an)裝(zhuang)不(bu)正(zheng)托(tuo)輥(gun)有(you)幾(ji)組(zu)難(nan)以(yi)判(pan)斷(duan)，可(ke)根(gen)據(ju)帶(dai)條(tiao)跑(pao)偏(pian)範(fan)圍(wei)，一(yi)組(zu)組(zu)調(tiao)正(zheng)托(tuo)輥(gun)，將(jiang)帶(dai)條(tiao)跑(pao)偏(pian)方(fang)托(tuo)輥(gun)順(shun)帶(dai)條(tiao)運(yun)行(xing)方(fang)向(xiang)前(qian)移(yi)或(huo)將(jiang)另(ling)一(yi)側(ce)托(tuo)輥(gun)反(fan)移(yi)，移(yi)動(dong)距(ju)離(li)以(yi)帶(dai)條(tiao)跑(pao)正(zheng)為(wei)限(xian)。調(tiao)整(zheng)帶(dai)條(tiao)移(yi)動(dong)托(tuo)輥(gun)支(zhi)架(jia)時(shi)，應(ying)在(zai)托(tuo)輥(gun)支(zhi)架(jia)與(yu)機(ji)架(jia)上(shang)衝(chong)長(chang)孔(kong)。有(you)時(shi)某(mou)點(dian)托(tuo)輥(gun)發(fa)生(sheng)停(ting)轉(zhuan)、脫落、黏泥、缺油等故障。應采取措施進行清掃、注油、更換托輥等，減少托輥阻力，消除膠帶在固定點跑偏。
(3)立(li)輥(gun)糾(jiu)偏(pian)法(fa)膠(jiao)帶(dai)運(yun)行(xing)時(shi)總(zong)往(wang)一(yi)邊(bian)跑(pao)偏(pian)，可(ke)在(zai)膠(jiao)帶(dai)跑(pao)偏(pian)處(chu)將(jiang)托(tuo)輥(gun)豎(shu)直(zhi)安(an)裝(zhuang)，一(yi)方(fang)麵(mian)由(you)於(yu)立(li)輥(gun)作(zuo)用(yong)力(li)使(shi)膠(jiao)帶(dai)強(qiang)行(xing)複(fu)位(wei)，另(ling)一(yi)方(fang)麵(mian)，由(you)於(yu)立(li)輥(gun)與(yu)膠(jiao)帶(dai)邊(bian)緣(yuan)摩(mo)擦(ca)作(zuo)用(yong)，降(jiang)低(di)了(le)膠(jiao)帶(dai)跑(pao)偏(pian)側(ce)的(de)線(xian)速(su)度(du)，使(shi)用(yong)膠(jiao)帶(dai)向(xiang)另(ling)一(yi)側(ce)移(yi)動(dong)直(zhi)至(zhi)複(fu)位(wei)。
(4)機架校正膠帶運行向同一側跑偏，並在某一位置較嚴重，說明托輥支架或機架扭曲不正．應校正托輥支架或機架的垂直度和水平度，更換扭曲嚴重的托輥支架或修複機架。
