EVA Sheet Machine Line

Iphepha le-EVA (i-ethylene vinyl acetate copolymer) yimveliso yeplastiki eqhelekileyo, esetyenziswa ngokubanzi kwiinkalo ezahlukeneyo ezifana nempahla yezihlangu, imithwalo, izixhobo zemidlalo, iithoyi, imveliso ye-elektroniki yokupakisha i-cushioning, iimethi zomgangatho, iifilimu zokuncamathela ezishushu ezinyibilikayo, njl.

Indlela ephambili yokuvelisa amaphepha e-EVA kukubumba i-extrusion, kunye nezixhobo ezihambelanayo yi-EVA sheet extrusion production line. Lo mgca wemveliso unezinto ezifanayo kunye nomgca wephepha le-PP / PE elikhankanywe ngaphambili, kodwa ngenxa yeempawu zezinto ze-EVA (ikakhulukazi ukuthamba, ukuqina okuhle, kunye nokwenzeka kogwebu), izixhobo nazo zineempawu zayo ezizodwa.

Umgca opheleleyo womatshini wephepha le-EVA ikakhulu uqulathe la macandelo alandelayo:

1. Inkqubo yokwenziwa kwezinto ezikrwada

·Umsebenzi: imathiriyeli ekrwada ye-EVA ubukhulu becala ikwimo yegranular. Ukuba ukuvelisa amaphepha e-EVA anegwebu, kuyimfuneko ukongeza i-agent e-foam (efana ne-AC ye-foaming agents) kunye nezinye izongezo (ii-agent ezidibanisayo, i-lubricants, njl.).

·Izixhobo:

·Umatshini wokutyisa ozenzekelayo: Ukuthutha amasuntswana e-EVA ukusuka kwisisele ukuya kwi-extruder hopper.

·Indlela yokulinganisa isondlo: Esi sisixhobo esingundoqo sokwenza amaphepha amagwebu. Ngokuqhelekileyo, isikali sokulinganisa ilahleko yobunzima sisetyenziselwa ngokuchanekileyo nangokuqhubekayo ukuxuba amasuntswana e-EVA, i-agent egwebu i-masterbatch, ii-colorants, njl.njl. ngokomlinganiselo kunye nokuzondla kwi-extruder ukuqinisekisa uzinzo olupheleleyo lomlinganiselo wefomyula, into efunekayo ukuze ufumane umgangatho ofanayo wogwebu.

2. Extruder

·Umsebenzi: Nyibilika, yenza iplastiki, kwaye udibanise ngokulinganayo imathiriyeli ekrwada ye-EVA. Kumaphepha e-foam, kuyafuneka ukuba usasaze ngokulinganayo i-agent ye-foam kwi-melt.

·Uhlobo:

·I-screw extruder enye: ilungele ukuvelisa amashiti e-EVA angaphumi-gwebu aqhelekileyo, anesakhiwo esilula kunye nexabiso eliphantsi.

·I-Parallel kunye ne-coroting twin{0}}i-screw extruder: ukhetho oluqhelekileyo nolusebenzayo. Impembelelo yayo yokuxuba igqwesile, enokuthi isasaze ngcono ii-agent ezinegwebu kunye ne-pigments, iqinisekise ubushushu obufanayo bokunyibilika, kwaye ivelise umgangatho ozinzileyo wephepha. Ngokukodwa ngokufanelekileyo ukuzaliswa okuphezulu kunye neemveliso ze-EVA ezinogwebu.

3. Umtshintshi womnatha

·Umsebenzi: Hlunga ukungcola kunye namasuntswana angenaplastiki ekunyibilikeni, thintela ukuvaleka kokungunda, kwaye uqinisekise ukucoceka kwemveliso kunye nomgangatho ophezulu. Ngokuqhelekileyo, yi-hydraulic etshintsha isikrini esizenzekelayo esinokutshintsha isikrini sokucoca ngaphandle kokumisa umatshini, ukuqinisekisa imveliso eqhubekayo.

4. Ngundo

·Umsebenzi: Yenza iplastiki enyibilikisiweyo etyhidiweyo ibe kububanzi obufunwayo nobungqingqwa.

·Uhlobo: Ikakhulu kusetyenziswa i-hanger yohlobo lwe-flat die head, idizayini yomjelo wayo wokuhamba inokuqinisekisa ukuba imathiriyeli etyhidiweyo isasazwa ngokulinganayo kububanzi bonke, ngaloo ndlela ifumana amaphepha anobungqingqwa obungaguqukiyo.

·Iimpawu: Umlebe wokungunda udla ngokuza nesixhobo esihle-sokulungisa esinokuthi silungelelanise kakuhle isikhewu kwiindawo ezahlukeneyo ukulawula ukutyeba kobume beshiti.

5. Ikhalenda yomqulu emithathu

·Umsebenzi: Esi sesona sixhobo sokubunjwa kwimveliso yephepha le-EVA.

·Ukupholisa kunye nokumila: Ibillet enyibilikisiweyo ephezulu{0}}ephezulu ephuma kumngundo ingeniswe ngoko nangoko kumsantsa ophakathi kweerola ezintathu, ipholiswe ngokukhawuleza ngamanzi okupholisa ngaphakathi kweerola, kwaye yaqina kwaye yamila.

·Qinisekisa ubukhulu kunye nesiphumo somphezulu: Ubukhulu bokugqibela kunye nokucwebezela komphezulu (iglosi okanye i-matte) yeshiti imiselwa ngumsantsa phakathi kweerola ezintathu kunye nokuguda komphezulu kweerola.

·Iimpawu: Iirola ezintathu ziyakwazi ukulungelelanisa ngokuzimeleyo isantya kunye nobushushu ukuze zihlangabezane neemfuno zenkqubo ezahlukeneyo.

6. Iyunithi yokutsala

·Umsebenzi: Khokela ishiti elipholileyo nelimile kakuhle kwisixhobo sokujija.

· Ukubunjwa: Ngokuqhelekileyo kuqulunqwe enye okanye izibini ezininzi zeerubha okanye i-silicone rollers, ukubonelela nge-traction efanayo kunye nokuthintela ukuguqulwa kokwelula.

7. Izixhobo zokukhangela kwi-Intanethi (ukhetho kodwa lubalulekile)

·Ireyi yeBeta okanye igeyiji yobukhulu be-infrared: Ukuskena kwexesha lokwenyani kunye nokuboniswa kwegophe elinqamlezileyo leshidi kwicandelo lokutsala, kwaye unokunika ingxelo ngedatha kwinkqubo yohlengahlengiso lwemilebe ezenzekelayo yokungunda ukufikelela kulawulo lokutyeba oluzenzekelayo (ATC), iphucula kakhulu ukuhambelana komgangatho.

8. I-Winder

·Umsebenzi: Roll iphepha libe yimilo eqengqelekayo. Ngenxa yokuthamba kwamashiti e-EVA, ukulawula ukuxinezeleka okujikajikayo kubalulekile.

·Uhlobo:

·Umatshini wokujija osembindini: ukujija ngokuqhuba undoqo ukuze ujikeleze, ufanelekile kwiinkcukacha ezahlukeneyo.

·Umatshini wokujija ongaphezulu: Uqhuba umphandle wekhoyili ukuze ujikeleze ngokukhuhlana, ofaneleke ngakumbi kwizinto ezithambileyo nezinokukhubazeka ngokulula kwaye unokugcina ngcono ukumila okucocekileyo kwekhoyili. Yindlela eqhele ukusetyenziswa ngokujija kwi-EVA sheets.

·Isixhobo sokugqibela{0}esiphezulu sixhotyiswe ngesikhululo esijikelezayo esiphindwe kabini, esinokutshintsha iireli ngaphandle kokumisa umatshini, siphumeze imveliso ezenzekelayo eqhubekayo.

9. Inkqubo yokulawula umbane

·Umsebenzi: 'Ingqondo' yomgca wemveliso. Ukwamkela ulawulo lwe-PLC kunye nesikrini esidibeneyo sokuthintela, zonke iiparameters zenkqubo ezifana neqondo lokushisa, isantya se-screw, isantya se-roller, i-traction kunye ne-winding tension yecandelo ngalinye inokumiselwa ngokuchanekileyo kwaye ilawulwe.

EVA particles+foam masterbatch+colorant ->weight loss metering feeding system ->twin-screw extruder (melting, mixing, foaming agent decomposition) ->screen changer (filtering impurities) ->hanger mold (forming) ->three roll calender (cooling, shaping, calendering) ->traction machine ->thickness gauge (online detection) ->winding machine (rolling) ->EVA sheet imveliso egqityiweyo

Isixhobo sephepha le-EVA esinegwebu eliqhelekileyo Isixhobo samaphepha e-EVA

Isixokelelwano semathiriyeli ekrwada kufuneka sixhotyiswe ngezikali eziphezulu-ezichanekileyo zokunciphisa ubunzima bokongeza ii-agent ezibilayo. Umatshini wokutyisa oqhelekileyo unokuhlangabezana neemfuno.

I-extruder ineemfuno eziphezulu kakhulu zokuxuba kunye nokusabalalisa isakhono sesikrufu, kunye ne-twin{0}}izikrufu ezikhuphayo ziyakhethwa. Isikrufu esinye okanye isikrufu samawele singasetyenziswa.

Ulawulo lwenkqubo lufuna ukuchaneka ngakumbi. Ulawulo lobushushu luchaphazela ngokuthe ngqo umlinganiselo we-foaming kunye nesakhiwo seseli. Ilula ngokwentelekiso.

Ulwakhiwo lokungunda luyafana, kodwa uyilo kufuneka luthathele ingqalelo ukunyibilika kwento enyibilikayo enegwebu. Intloko yokubumba i-hanger eqhelekileyo.

Izixhobo ezilandelayo, i-calender roll ezintathu, zibalulekile ekulawuleni ubukhulu kunye nomphezulu wephepha le-foam. Ikhalenda yoluhlu oluthathu nayo iyafuneka.

1. Ukubekwa kwemveliso: Cacisa ukuba eyona mveliso iphambili ilugwebu okanye ayilugwebu? Yintoni umlinganiselo wogwebu? Oku kumisela ngokuthe ngqo ukukhethwa kwee-extruders kunye neenkqubo zokutya.

2. Iimpawu zemveliso: Ubuninzi bemveliso yobuninzi (njenge-1000mm, i-1300mm, i-1500mm, njl.) kunye noluhlu lobuninzi (ngokuqhelekileyo i-0.5mm-10mm).

3. Inqanaba le-automation: Ngaba ufuna ukufakwa kwemitha okuzenzekelayo, ukutshintshwa kwesikrini ngokuzenzekelayo, impendulo yokulinganisa ubukhulu obuzenzekelayo (ATC), kunye nokuzijika okuzenzekelayo? Ezi zinokuphucula kakhulu umgangatho wemveliso kunye nokuzinza, kodwa nokunyusa iindleko.

4. Iimfuno zokuvelisa: Qinisekisa ubungakanani bemodeli ye-extruder (i-screw diameter).

5. Ukukhethwa kwababoneleli: Ukusetyenzwa kwe-EVA kufuna amava enkqubo ephezulu. Ababoneleli ngezixhobo ngeteknoloji yenkqubo esele ikhulile, abakwaziyo ukunika isikhokelo sefomula, ukufakwa kunye nokugunyaziswa, kunye noqeqesho lwenkqubo kufuneka kukhethwe.

Isishwankathelo: Isixhobo sephepha le-EVA ngumgca wemveliso we-extrusion ovuthiweyo ngokobuchwephesha, kodwa ulungelelwaniso lwayo lunokwahluka kakhulu ngokuxhomekeke kwimveliso yeemveliso ezinogwebu okanye ezingenagwebu. Undoqo ulele kuthutho lwemathiriyeli ekrwada echanekileyo, ukuxuba okunyibilikayo okusebenzayo, ukupholisa okuchanekileyo, kunye nokujika okuzinzileyo. Ngaphambi kokuba wenze utyalo-mali, kubalulekile ukunxibelelana ngokupheleleyo neemfuno zemveliso yakho kunye nomthengisi wezixhobo.
