Makina ophimbira a rabara ndi chida chophatikizira chodziwikiratu chokulunga ndi kukulunga mphira pamwamba pa mpukutu wa rabara, womwe umathandizira kwambiri kupanga bwino kwa fakitale yopukutira mphira pokonza ndi kupanga zinthu zopukutira mphira.Ndi makina zida basi kuzimata ndi kuzimata mphira mu mphira mpukutu processing.
1. Tanthauzo la dzina
Kodi makina ophimba a rabara rolerl ndi chiyani?Chida ichi ndi mtundu wa zida zopangira machira a mphira, omwe amagwiritsa ntchito extruder kuti atulutse filimu ya makulidwe ena ndi m'lifupi ndikuwongolera pakatikati pa mphira wa mphira mwadongosolo komanso wosasunthika.Makina omangira mphira sangangowonjezera mtundu wa mphira wophimba machira, kugwiritsa ntchito mphira wa makulidwe osiyanasiyana pamipukutu yamitundu yosiyanasiyana, kufupikitsa nthawi yopanga, kupititsa patsogolo kuchuluka kwa makina, kuchepetsa kuchuluka kwa ogwira ntchito, komanso kuthetsa vuto kuti zimango ndi zochita zokha zida ndondomeko sangathe anazindikira chifukwa kusatsimikizika kwa mankhwala ndi zosiyanasiyana miyeso ndi specifications mu kupanga mphira mpukutu.Ili ndi chiyembekezo chachikulu chamsika komanso kudalirika kwamakasitomala.
2. Zofunikira pakufunsira
Njira yopangira mphira nthawi zambiri imakhala ndi maulalo akuluakulu atatu opangira: kupanga mphira, kutulutsa mphira, komanso chithandizo chapamwamba.Ulalo wopangira mphira ndi gawo loyambira lofunikira kwambiri, lomwe ndi njira yophimba pachimake chachitsulo ndi mphira.Ngati pali vuto mu ulalo uwu, mpukutu wa rabara wopangidwa sungathe kukwaniritsa zofunikira zomwe zikuyembekezeka.Ndi chitukuko cha extruders m'nyumba, akamaumba jekeseni ndi matekinoloje ena, machira kupanga machira pang'onopang'ono anayamba msewu wa makina ndi zokha.Chifukwa cha zofunikira zosiyanasiyana za machira, pali zonyansa zilizonse, mabowo amchenga ndi thovu, osatchulapo * *, zolakwika, ming'alu ndi kusiyana kofewa komanso kolimba komweko, kotero kuti ulalo wopangira machira umakhala wolimba kwambiri.Kugwiritsa ntchito msika wamakina omangira machira kumakwaniritsa cholinga chokwaniritsa kamvekedwe kake, Njira yonse yopangira mphira yophimba mphira imatenga liwiro lofananira, mphamvu yokhazikika, kukhazikika kokhazikika kwa mphira ndi machitidwe ena, omwe apambana kuzindikirika ndi kudalira msika.
3. Mfundo yogwira ntchito
Limbikitsani mbali imodzi ya mpukutuwo kuti ukhale wokutidwa pa nsagwada zitatu za chuck pamutu wa bedi la makina opangira mphira, ndipo mapeto ena amathandizidwa ndi omwe amaikidwa kumapeto kwa bedi.Pamene mphira ya mphira yakulungidwa, yambani bedi loyamba, ndipo nsagwada zitatu za chuck zimayamba kuyenda mozungulira mozungulira, pamene mphuno yoyendetsedwa imazungulira.M'kati mwa kusinthasintha kothamanga kwapakati pa mpukutuwo, yambitsani mphira wa mphira, ndi pulasitiki ndikutulutsa mzere wofanana ndi mphira kudzera muzowonjezera zoziziritsa kukhosi, Mzere wa mphira umaperekedwa kumakina opindika kudzera munjira yolumikizira mphira ndi chiwongolero. wodzigudubuza kuti ayambe kupiringa ndi kuphimba pachimake mphira.Njira yokhotakhota pachimake chodzigudubuza ndi tepi yomatira kwenikweni ndi chifukwa cha kuphatikiza kusuntha kuwiri.
Ngati mzere wa mphira wokhala ndi m'lifupi mwake ndi makulidwe ake umayenda mwachangu kuzungulira X axis (mphira wozungulira mphira) pamwamba pa mpukutuwo, ndipo makina omangira amayenda molunjika pamzere wa X, mzere wa rabara umayenda molunjika. kumamatira ku mpukutuwo pafupipafupi.Makulidwe osiyanasiyana a mpukutu wa rabara amatha kupezeka podyetsa makina omangira mphira motsatira Y axis (rabara roll radial direction).
Kuti mukwaniritse makulidwe a mphira wofunikira pakumangirira mpukutu wa rabara, makulidwe a mphira wa mphira wa extruder pamalo axial a mpukutu wa rabara ayenera kuwongoleredwa, ndiye kuti, kuchulukana pakati pa mzere wa rabara ndi mzere wa rabara. .Kuchuluka kwa kuphatikizikako kumakhala kokulirapo, kukhuthala kwa mapindikidwe, ndi kucheperako kuphatikizikako, kumachepetsanso makulidwe okhotakhota.Liwiro lomasulira la mphira wopukutira makina opangira mphira limatsimikizira mwachindunji kukula kwa kuchuluka kwapang'onopang'ono pokhudzana ndi liwiro la kuzungulira kwapakati.
4. Zida zikuchokera
Zigawo zazikulu zamakina opiringizika a mphira a PTM ndi awa: mphira wozizira wowonjezera, nsanja yoyenda, chipangizo chomangira, cholumikizira mizere ya mphira, bedi lodzigudubuza, ndi mota yamagetsi yazida zofananira.
(1) The ozizira kudyetsa mphira extruder makamaka ntchito kukonzekera n'kupanga mphira ndi ena mapeto mawonekedwe kwa kupanga mphira mpukutu kuzimata.Zimadziwika kuti mphira wowonjezera akhoza kudyetsedwa mwachindunji popanda kutentha, ndipo voliyumu ya extrusion ndi yayikulu, kutentha kwamadzi kumakhala kochepa, mtengo wa unit extrusion volume ndi wotsika, mphamvu yogwiritsira ntchito mphamvu ndi yochepa, ndipo mphira wotuluka ndi yunifolomu. ndi wandiweyani.
(2) Panthawi yokhotakhota ya mpukutu wa rabara, nsanja yoyendayenda idzayenda mumzere wowongoka wowongoka motsatira njira ya radial ya mpukutuwo, ndipo kusuntha ndi liwiro la nsanja zidzayendetsedwa.Imayendetsedwa ndi servo motor ndi servo dalaivala yothamanga kwambiri komanso kuwongolera kwakukulu.
(3) Chipangizo chomangira guluu ndiye gawo lalikulu la makina omangira mphira.Sikuti amangophimba pachimake mphira mpukutu, komanso chimakwirira mapeto a nkhope ya mphira mpukutu pachimake.Chida chomangirira chikamayenda motsatira nsonga ya mpukutuwo mpaka kumapeto kwa mpukutuwo ndi malo osinthira axis, chowongolera chopondera chomwe chimayikidwa pa chipangizocho chimafunika kuzungulira madigiri a 180 kuti chizolowerane ndi zokutira. ndege kuti ayambe ntchito yokutira.
(4) The zomatira tepi kufalitsa limagwirira ndi kusintha kutengera njira ya zomatira njira pamene axial pamwamba ndi mapeto a nkhope malo a zomangira mphira mpukutu pachimake atembenuza, ndi zomatira tepi apatuka kapena kugwa.Njira yotumizira tepi yomatira imafunikira osati kungoyendetsa tepi yomatira, komanso kusintha malo kuti muwonetsetse kuti tepi yomatirayo sipatuka kapena kugwa.
(5) Bedi lodzigudubuza limawoneka ngati lathe wamba lopingasa ndipo limapangidwa makamaka ndi maziko, mutu wa bedi, thupi la bedi, tailstock ndi njira yopatsira.Chibwano cha nsagwada zitatu chimayikidwa pamutu pa bedi, ndipo chuck yosunthika imayikidwa kumapeto kwa bedi kuti atseke mosavuta.Njira yopatsirana imatengera chotsitsa cha singano cha Baixian, chomwe chimayendetsedwa ndi unyolo.Chingwe chonyamulira chimawonjezedwa pamutu wa bedi ndi mchira wa bedi wodzigudubuza, womwe umagwiritsidwa ntchito makamaka pothandizira bedi, kotero kuti mpukutu waukulu wa rabara ukhoza kuwononga bedi lodzigudubuza.
