Byose Kubijyanye na Stretch Imashini Zikora

Filime irambuye, izwi kandi nko kurambura, ni ibintu by'ingenzi mu bikoresho byo gupakira no gupakira. Ipfunyika neza pallets, guhuza ibicuruzwa, kandi irinda ibicuruzwa mugihe cyo gutambuka no kubika. Ariko wigeze wibaza uburyo iyi firime ya plastike yoroheje, iramba ikorwa? Igisubizo kiri mubikoresho bihanitse: imashini irambuye ya firime.

Kumva uburyo izo mashini zikora nibyingenzi mubucuruzi ubwo aribwo bwose bwo gupakira, kohereza, cyangwa gukora. Aka gatabo kazakunyura mubikorwa byose, uhereye kubikoresho fatizo bikoreshwa kugeza ibice byingenzi bigize imashini nuburyo butandukanye bwo gukora. Mugihe cyanyuma, uzaba usobanukiwe neza nibijyanye no gukora firime yo mu rwego rwo hejuru irambuye nuburyo wahitamo imashini ibereye ibyo ukeneye.

Imashini ikora firime ndende niyihe?

A. imashini ikora firime irambuye ni umurongo wihariye wo gukora uhindura plastiki mbisi muri firime irambuye. Izi mashini zagenewe gushyushya, gusohora, gukonjesha, n’umuyaga ibikoresho bya pulasitiki mu mizingo minini, ishobora noneho gukatwamo ibice bito, bikoreshwa. Inzira isaba kugenzura neza ubushyuhe, umuvuduko, n'umuvuduko wo gukora firime hamwe nubunini bwifuzwa, bwumvikana, kandi burambuye.

Ibikoresho byibanze bikoreshwa ni Linear Low-Density Polyethylene (LLDPE), ikunze kuvangwa nizindi polymers nka metallocene LLDPE (mLLDPE) cyangwa Polyethylene nkeya (LDPE) kugirango yongere imitungo yihariye nko kurwanya gucumita, kwizirika, nimbaraga zikomeye.

Nigute Imashini Zirambuye Zikora?

Urugendo ruva kuri pellet ntoya kugeza kumuzingo urangiye wa firime irambuye irimo ibyiciro byinshi bigoye. Mugihe ibishushanyo byihariye byimashini ikora firime irashobora gutandukana, inzira yibanze ikomeza kuba imwe. Irashobora gucikamo intambwe enye zingenzi: gukuramo, gukonjesha, kuzunguruka, no kunyerera.

1. Gukuramo: Gushonga Ibikoresho Byibanze

Inzira itangirira kuri extruder. Pellet ya Raw LLDPE, hamwe ninyongeramusaruro zose, zigaburirwa kuva hopper mukibindi kirekire, gishyushye kirimo umugozi uzunguruka.

· Gushyushya no gushonga: Mugihe umugozi uhindutse, usunika pelletike imbere. Ubushyuhe bukabije buturuka ku kuzenguruka kwa screw, bufatanije n’ibintu byo gushyushya byo hanze kuri barriel, bishonga pellet mubintu bya pulasitike bihuriweho, bishongeshejwe byitwa 'gushonga. '

· Kuvanga no Kotsa igitutu: Imashini ntabwo yagenewe gutwara ibintu gusa ahubwo no kuyivanga neza no kubaka igitutu. Ibi byemeza ko gushonga ari kimwe mubushyuhe no guhora mbere yuko biva muri extruder.

Imashini nyinshi zigezweho zikoresha uburyo bwinshi bwo gufatanya. Ibi bikubiyemo gukoresha ibicuruzwa byinshi kugirango ushonge ibintu bitandukanye icyarimwe. Ibice byashongeshejwe noneho bihuzwa mukugaburira mbere yo kubumbwa mumurongo umwe, ibice byinshi bya firime. Ibi bituma ababikora bakora firime ifite imiterere itandukanye; kurugero, igice cyo hanze 'kwizirika ' hamwe ningingo ikomeye, irwanya gucumita.

2. Gutegura firime no gukonjesha: Abakinnyi nuburyo bwo kuvuza

Iyo plastiki yashongeshejwe imaze kuva muri extruder, igomba kuba murupapuro ruto kandi igakonja vuba. Hariho uburyo bubiri bwibanze kuri buri, buri firime itanga ibintu bitandukanye:

Uburyo bwa Filime

Ubu ni bwo buryo busanzwe bwo gukora firime yo mu rwego rwo hejuru.

· Gukora: plastike yashongeshejwe ivanwa mu kayunguruzo keza, igakwirakwiza mu rupapuro ruto.

· Gukonjesha: Uru rupapuro ruhita rujugunywa murukurikirane runini, rukonje, bakunze kwita 'gukonjesha. ' Iyi mizingo ikonje vuba kandi igakomera plastike. Umuvuduko wibikorwa byo gukonjesha ningirakamaro muguhitamo neza film nibiranga.

Ibyiza bya Filime Yabakinnyi:

· Byumvikane neza, byemerera gusikana byoroshye barcode.

· Hatuje utabishaka uhereye kumuzingo.

· Umubyimba uhoraho kandi wiziritse.

· Umuvuduko mwinshi wo gukora.

Uburyo bwa Firime Uburyo

Ubu buryo ntibusanzwe kuri firime irambuye ariko ikoreshwa cyane mubindi firime ya plastike nkimifuka yo guhaha.

· Gukora: plastike yashongeshejwe isohoka mu rupfu ruzenguruka hanyuma igahatirwa guhagarikwa hejuru kugirango ikore umuyoboro muto wa plastiki.

· Gukonjesha: Umwuka uhuhwa hagati ya thetube, ukaguka nka ballon kugeza kuri diameter yifuzwa n'ubugari. Hanze yibi 'bubble ' ikonjeshwa nimpeta yihuta yumuyaga. Igituba noneho kirasenyuka kandi kiringaniye mumpapuro.

Ibyiza bya Filime Yavuzwe:

· Gutobora cyane no kurwanya amarira.

· Imbaraga nini zo gufata imitwaro.

· Urusaku rudasanzwe, rushobora kuba imbogamizi ku kazi kamwe.

3. Gukata impande zose no kuvura

Mugihe firime ikomera, impande zayo zirashobora kuba ndende kandi zidahuye. Sisitemu yo gutema impande ikoresha ibyuma bikarishye kugirango ikureho ubusembwa, urebe ko firime ifite ubugari buhoraho. Ibikoresho byacuzwe akenshi byegeranijwe kandi bigasubirwamo bigasubira mubikorwa kugirango bigabanye imyanda.

4. Kuzunguruka no kunyerera

Icyiciro cyanyuma ni uguhindura urupapuro rukomeza rwa firime mumuzingo munini 'jumbo '.

· Priming Winding: Umuyaga ukusanya firime yarangiye kumurongo munini, ugakora umuzingo wa jumbo ushobora gupima toni nyinshi. Umuvuduko n'umuvuduko bigomba kugenzurwa neza kugirango wirinde iminkanyari cyangwa inenge.

· Kunyerera no gusubiza: Umuzingo wa jumbo uhita wimurirwa mumashini isunika kandi isubiza inyuma. Hano, ntigikubiswe kandi igabanijwe mubugari bwagutse, nko kuzunguruka intoki (mubisanzwe santimetero 12-20) cyangwa imashini. Utuzingo duto noneho turakomereka ku makarito yumuntu ku giti cye, yiteguye gupakira no kohereza.

Ibice byingenzi bigize imashini irambuye

Gusobanukirwa ibice byingenzi bigize a kurambura imashini ikora firime ifasha gushima ubunini bwayo nibintu bigira ingaruka kumiterere ya firime.

· Extruder: Umutima wimashini, ushinzwe gushonga no gukanda resin ya plastike. Gufatanya gusohora bizaba bifite extruders nyinshi.

· Flat Die (Cast Method) cyangwa Uruziga Rupfa (Uburyo bwavuzwe): Ikintu kigizwe na plastiki yashongeshejwe mumpapuro cyangwa umuyoboro.

· Chill Rolls: Ibinini binini, bikonje imbere bikomeza firime mugikorwa cyo gukina. Ubuso bwabo burangira hamwe nubushyuhe nibyingenzi kubwiza bwa firime.

· Impeta yo mu kirere (Uburyo bwavuzwe): Itanga umwenda utomoye wumwuka kugirango ukonje firime.

· Winding Sisitemu: Imashini zihindura firime kuri cores. Sisitemu zigezweho zifite moteri yo kugenzura kandi irashobora gukora impinduka zihuse.

· Sisitemu yo kugenzura PLC: Programmable Logic Controller (PLC) ni ubwonko bwimashini. Ikoresha ecran ya ecran kugirango yemere abashoramari gukurikirana no kugenzura buri kintu cyose, uhereye kubushyuhe bukabije kugeza kumuvuduko ukabije hamwe nubunini bwa firime.

Guhitamo Imashini ibereye

Kubucuruzi bushaka gushora imari mumashini arambuye ya firime , icyemezo kiza mubintu byinshi:

· Ingano yumusaruro: Imirongo yihuta ya firime ikwiranye nibikorwa binini, mugihe umusaruro muto cyangwa wihariye ushobora gukoresha uburyo butandukanye.

· Ubwoko bwa Filime: Ibintu byifuzwa byibicuruzwa byanyuma - bisobanutse, birwanya gucumita, gufatana uruhande rumwe - bizagaragaza niba umurongo wa firime wakinnye cyangwa uhuhwa bikwiye.

· Umubare w'Imiterere: Imashini zirashobora kuva kumurongo woroheje wa 3-umurongo kugeza kuri sisitemu igoye 5, 7, cyangwa 9. Ibice byinshi byemerera kugenzura byinshi kumiterere ya firime kandi birashobora kugabanya ibiciro byibikoresho ukoresheje ibikoresho bihendutse bitunganijwe neza murwego rwibanze.

· Automation: Imashini zigezweho zitanga urwego rwo hejuru rwo kwikora, kuva guhinduranya byikora kugeza kumurongo wimbaraga za interineti, bigabanya ibiciro byakazi kandi bitezimbere.

Kazoza Kurambuye Gukora Filime

Inganda zikomeje gutera imbere. Kuramba ni imbaraga zikomeye zo gutwara, hamwe nababikora bakora firime yoroheje, ikomeye igabanya ikoreshwa rya plastike bitabangamiye imikorere. Hariho kandi kwibanda ku kwinjiza ibintu bitunganijwe neza muri firime irambuye.

Uko ikoranabuhanga ritera imbere, imashini zirambuye za firime ziragenda zikora neza, zikoresha, kandi zishobora gukora firime zihariye. Ibi bishya byerekana ko firime irambuye ikomeza kuba igisubizo cyingirakamaro, cyigiciro cyinshi cyo kubona ibicuruzwa kwisi yose.
