Ubuchwepheshe bokubopha uphawu nemishini

Ukubekwa uphawu kubhekisele ezinqubweni ezahlukahlukene zokubekwa uphawu kwenziwa ngemuva kokupakishwa Amabhokisi okupakisha okuphelele we-Baklava Umkhiqizo onezinto zokupakisha noma iziqukathi zokupakisha ukuqinisekisa ukuthi okuqukethwe kuhlala kwiphakheji futhi kugweme ukungcoliswa ngesikhathi sokujikeleza, ukuthutha, ukugcinwa kanye nokuthengisa. Inencazelo ebanzi futhi ibizwa nangokuthi ukubekwa uphawu, ukubekwa uphawu, noma ukubekwa uphawu. Ngemuva kokuqeda ukufakwa kwezinto zokwakhaAmabhokisi okupakisha okuphelele we-BaklavaEsitsheni, umshini obeka uphawu esitsheni ubizelwe imishini yokubopha uphawu. Iziqukathi ezahlukene zokufaka zinezindlela ezihlukile zokubopha, kanye nezinhlobo zezinhlobo zokuvalwa kwezindawo nemishini yokubopha uphawu zihlukene. Kunezinhlobo eziningi zezindlela zokubopha, izinto zokwakha kanye nezakhi ezisetshenziswa ekufakweni kwenqubo kanye nokupakisha. ezihlukaniswe ngezinhlobo ezilandelayo ngokusho kobukhona noma ukungabikho kwezinto zokwakha uphawu kanye nezindlela ezihlukile zokubopha.

(1)Azikho izinto zokubopha uphawu, kunokubekwa uphawu okucindezelwe okushisayo, ukubekwa uphawu kwe-welding, ukubekwa uphawu okuvinjelwe, ukugoqa uphawu nokubopha uphawu.

(2)Kunezinto zokwakha uphawu, kufaka phakathi ukubekwa uphawu okugoqa, ukubekwa uphawu okulimayo, ukubekwa uphawu kwengcindezi kanye nokusonteka kokusondelana.

(3)Kunezinto zokubopha uphawu ezisizayo. Lolu hlobo lokubekwa uphawu luhlanganisa ukubekwa uphawu lwe-ligation kanye nokubekwa uphawu kwetheyipu.

Empilweni yansuku zonke, le mikhiqizo yokubopha uphawu ingabonakala yonke indawo, njengamabhodlela engilazi ebhiya, uSoda nezinye iziphuzo zekhabhoni. Ngokuyinhloko imikhiqizo yokubopha uphawu lokubopha, okubizwa ngokuthi yi-Capling Machines. Amanzi asebhodleleni nemikhiqizo yezemithi avame ukubekwa uphawu ngokukhomba kwesikulufu, futhi abizwa ngesiko lemishini yokukhapha. Ukudla okusemathinini ezitsheni ze-tinyplate kuvalwe ukumboza nokubopha uphawu, okusetshenziselwa ukubizwa ngokwenza lula umshini. Ngeke ngibabhale ngakunye. Bonke bangabangesigaba semishini yokufaka.

 

1. Imisebenzi nezinhlobo zezikhangiso

Indlela yokufaka uphawu lokupakisha imikhiqizo usebenzisa ama-adhesives ibizwa ngokuthi inqubo yokunamathela. Izinzuzo zayo ziyinqubo elula, ukukhiqiza okuphezulu, amandla aphezulu okusatshalaliswa, ukusatshalaliswa kwengcindezi okufanayo, ukubekwa uphawu okuhle, ukuqina okubanzi, nokukhuphuka kokufakwa kwe-thermal kanye nokufakwa kwezakhiwo. Isetshenziswa kabanzi embonini yokufaka ehlanganisa izinto ezahlukahlukene ezifana nephepha, indwangu, izinkuni, ipulasitiki kanye nensimbi. Idlala indima ebalulekile ezinqubweni zokubekwa uphawu, ukukhiqizwa kwezinto ezibonakalayo, ukubekwa uphawu kwebhokisi, ukugoqa, nokulebula.

Kunezinhlobo eziningi zokunamathela ezinezithako eziyinkimbinkimbi, kanye nezinto eziningi zemvelo zemvelo nezokwenziwa zingasetshenziswa njengezinamathelayo. Ngokohlobo lwe-Base Material of Adhesive, lungahlukaniswa ngezinamathela ezinama-inorganic kanye nezinamathekisi eziphilayo; Ngokwendlela yomzimba yokunamathela, kungahlukaniswa izigaba ezintathu: uhlobo olunyibilikayo, uhlobo lwe-solvent nohlobo olushisayo olushisayo; Ngokusho kokuthi i-adhesive ifudunyezwa lapho isebenza, ihlukaniswe nge-glue ebandayo nokunamathela okushisayo okushisayo.

2. Ukubopha ama-glue obandayo akudingi ukufudumala futhi kwenziwa emazingeni okushisa asekamelweni.

Kukhona ukunamathela okuncibilikayo kwamanzi kanye nokunamathela okususelwa ku-solvent. Adshesives asuselwa ku-solvent alungele kuphela ukubopha okungama-120-degree kuncibilika okungasebenzisi imishini ye-waterline fusion ngenxa yemikhawulo ezinhlotsheni, ukuphepha, imithetho yokuvikela imvelo, kanye nokuphepha kokukhiqiza. Endabeni yezinamathela, izinamathiselo ezinyibilika amanzi zisetshenziswa ikakhulukazi ekukhiqizweni. Uhlobo lwe-dongji hlobo Xinheli lusetshenziswe isikhathi eside kunazo zonke ekupakisheni futhi lunomthamo omkhulu kunabo bonke. Izinzuzo zayo kungukusebenza okulula, izindleko zokuphepha eziphansi kanye namandla aphezulu okubopha. Ingahlukaniswa izigaba ezimbili: ukunamathela kwamanzi okunempilo kanye nokunamathela kwamanzi okuncibilikayo. Kungumsindo wemvelo osuselwa emanzini ngokulondolozwa kwamandla okuphansi namandla aphezulu. Isexwayiso sohlobo lwe-FU. Inhloso enkulu ukusetha amabhokisi nephepha. Yenziwe ngamashubhu ephepha lempuphu nezikhwama zamaphepha. Yenziwe ngofulawa ongavuthiwe noma imifino. Enqubweni yokukhiqiza ye-Wabo Cardboard, gwema ukusebenzisa isitashi. Anamathele. Izinzuzo zayo ukuthi kulula ukwakha futhi zinamathele kumathini wensimbi, kungahle kube ne-Bond Paper kahle, futhi inokumelana nokushisa okuhle. Okubi ukuthi ukuphambuka kwesikhonkwane kuncane.

Ukunamathelisa okumpofu kumapulasitiki kanye nokumboza, ukumelana kwamanzi ampofu. Izinto ezibonakalayo ezibonakalayo kanye nongqimba lokubulala, njenge-glue yezilwane, zingasetshenziswa njengengxenye eyinhloko ye-rewet yekhompiyutha yokubopha, kanye nokunamathela kwe-glue esomile: njenge-glue esomile, kusetshenziswa ikakhulukazi njengesinamatheli amabhodlela ebhiya. Ukufakwa okunamathela okunamathela, ngoba kungahlangana nokumelana nokucwiliswa kwamanzi okubandayo okudingekayo kwizikhwama ze-beer Bottle Label, futhi kungahlanzwa ngamanzi we-alkaline ngemuva kokuthi ibhodlela liphinde lisebenze kabusha. Ingasetshenziswa futhi ukwenza i-Chemical Compound esetshenziselwe i-Daizhi foil kanye ne-emulsonion yemvelo, enjenge-emulserion emhlophe ekhishwe ezihlahleni zenjoloba, okusetshenziselwa ukufakwa njengengxenye enkulu yezakhiwo zamaphethelo amaningi. Kungakwazi ukuzimela ngengcindezi, ngakho-ke kuvame ukusetshenziselwa amaswidi okucaca. Ukunamathela ngokugoqa, amabhokisi okubopha okunamathisela kanye nezikhwama zokubopha uphawu lwePhepha.

Anamanzi ancibilikayo ancibilikayo.

Iningi lalawa ma-adhesives anslin emulsion, ikakhulukazi i-polyvinyl acetate emulsion-stetate emulsion ukumiswa kwezinhlayiya ze-vinyl acid emanzini. Lolu hlobo lokunamathela lusetshenziswa kabanzi ku-Amabhokisi okupakisha okuphelele we-Baklava, njengokuthi kwakha, ukubekwa uphawu noma ukubhala amabhokisi, amabhokisi, amashubhu, izikhwama namabhodlela. Ngenxa yochungechunge lwayo lwezakhiwo ezinhle kakhulu, zithathe indawo okufakwe ngaphansi kwezibalo zemvelo.

Inqubo yokubopha ibhondi ebandayo ebandayo

Inqubo yokubopha isibopho sokunamathela okubandayo ingasebenza ngesandla noma ngemishini yokuhlanganisa. Izinqubo zokusebenza eziphambili zokuhlanganisa yilezi: ukuhlanganisa, ukucindezela nokwelapha (ukuguquguquka). Ukwelapha yinqubo lapho amanzi noma i-organic solvent eyehlayo i-glue ebandayo ivele ivele ize zinamathele ngokwawo ziqinile. Ngemuva kokuthi i-adhesive isetshenziswa ku-adrend, idinga ukuhlala esimweni esiseduze isikhathi eside ize iqina. Sebenzisa ibhulashi noma isibhamu sokufafaza lapho ufaka isicelo ngesandla. Lapho imishini yokuhlanganisa imishini, kunezindlela ezintathu ezisebenzayo: D Roller Coating indlela. I-glue ebandayo esitsheni isatshalaliswa ngokujikeleza ama-roller. Kunezindlela ezimbili zokuguqula ubukhulu be-glue: lapho i-roller i-cylindrical ebushelelezi, ingashintshwa ngegebe phakathi kwe-wheel surce kanye nesikhafu; Lapho indawo ye-roller inama-grooves, kuya ngokujula kwe-groove. Indlela ye-roller coating ingasebenzisa ama-adhesives emazingeni okushisa asekamelweni. Isakhiwo semishini silula futhi sisetshenziswa kabanzi ekugodleni imishini yokunamathisela ye-carton. Ngoba ingafaka ngokuphelele i-glue ngokuphelele kumafolda ebhokisini, ibhokisi lingavalwa ngokuphelele noma ngabe okuqukethwe ku-powder form. Kodwa-ke, imishini idinga ukuhlanzwa nsuku zonke, futhi ukulahlekelwa kokunamathelayo kukhulu; Uma kusetshenziswa izixazululo ze-organic, izindaba zokuvikela ezemvelo zidinga ukubhekwa.

3. Indlela ye-nozzle coating. Kunezindlela ezimbili zokufafaza glue nge-nozzle.

Indlela yokuhlinzeka ngokunamathela ku-nozzle kungaba ithangi lokucindezela noma iphampu yokucindezela. Lapho ufafaza glue ngendlela engeyona eyokuxhumana, kunebanga elithile phakathi kwe-nozzle kanye nento okufanele ilandelwe, futhi iphampu yengcindezi enengcindezi ephakeme yokufafaza isetshenziswa kakhulu. Ngaphezu kwalokho, ngokombono wesondlo, ngoba

Ngezinto zokwakha ezifana nekhadibhodi elonakalisiwe lapho iphephaAmabhokisi okupakisha okuphelele we-BaklavaIzikhala zivame ukuqongelela ku-nozzle, indlela engeyona eyokuthintwa kufanelekile. Uma kuqhathaniswa nendlela ye-roller coating, i-coint yokuhlanganisa yokuhlangana engaxhumana nayo ingashintshwa ngokunqumela, futhi imishini ayidingi ukuhlanzwa nsuku zonke; Kodwa-ke, njengoba i-glue ifafazwe nge-nozzle encane, kunenkinga yokuthi i-glue izoma futhi ivimbe i-nozzle. Ngalesi sizathu, ezinye izinyathelo zidinga ukuthathwa zinyathelo zifaka ukubeka i-nozzle endaweni enomswakama noma ukushaya umswakama ngasekupheleni kwe-nozzle lapho kumiswa komugqa womhlangano. Ngaphezu kwalokho, ezinye izinamathesi zizosheshisa ukubhujiswa kwama-nozzles wensimbi, okufanele kubhekwe lapho ukhetha.

Indlela ye-acid inkungu ye-glue coating indlela. Akunamehluko omkhulu ekubukeni kwe-Spray Gluing kanye nezinhlelo ze-nozzle gluing. Umehluko ukuthi i-gluing eyomile yenza i-glue ebandayo iye yasakazekela ekwakhekeni okuqondile, ngenkathi i-spray gluing yenza ukubheja okubandayo kusakazeke ngephutha, isizathu ukuthi ukunamathela kudinga indawo enkulu. Umphumela omuhle wobuhlobo obuhle ungatholwa ngokusebenzisa inani elincane le-glue, nesikhathi sokukhanya kungafinyezwa. Okubi ukuthi umugqa wokuqala ufiphele. Isetshenziselwa kakhulu ukubopha amabhokisi acwengekile amabhokisi 3. Hot Melt Adhesive Bonding

Kunezindlela ezintathu zokuguqula ingcindezi ngaphakathi kokusebenza kwemishini yendwangu noma igumbi le-organic solvent lapho imishini ye-roller ivaliwe.

I-Hot Melt Adhesive iyinhlangano eqinile eqinile ngokususelwa kuma-thermoplastic polymers. Inqubo yayo yokubopha yile: incibilika ukunamathela, ukunamathela, ukucindezela nokuqina (ukupholisa). Uketshezi lwe-coating lufudumele futhi luncibilikisiwe glue, futhi ukuqina kuyinqubo yokupholisa i-glue ebilisiwe. kwehlukile kubanda

I-glue key uvele ivele. Ngoba isikhathi esipholile sifushane kakhulu kunesiphi isikhathi sokuhwamuka, singazivumelanisa nejubane lokukhiqiza eliphakeme lemigqa yokukhiqiza ezenzakalelayo. Kuyinto ebaluleke kakhulu yokunamathela epakishe yamanje. Kukhona ezintathu ezisetshenziswa kakhulu ezisetshenziswayo ezishisayo ezishisayo. Owokuqala yi-ethylene-vinyl acetate copolymer (EVA), engahlanganiswa ne-wax futhi efaka ama-resin ukwenza ukunamathela okusebenzayo. Umsebenzi we-wax ukunciphisa i-viscosity futhi ulawule isivinini sokwelapha, ukuguquguquka nokumelana nokushisa okunamathelayo, indima ye-resin exakile ukulawula i-viscosity kanye nokunamathelisa. Uhlobo lwesibili lunamathela okushisa okushisayo ngokusekelwe ku-polyethylene ye-molecular ephansi, esetshenziselwa kakhulu ukubopha amaphepha, njengokubekwa uphawu kwe-carton kanye nokubekwa uphawu kwesikhwama. Uhlobo lwesithathu lokunamathela olususelwa ku-amorphoous polypropylene lusetshenziselwa iphepha lokulambisa ukukhiqiza izinto zokupakisha ezingamelana namanzi noma ukugcwaliswa kwezinto zokuhamba ezihlanganisiwe.

Ngaphezu kwalokho, kukhona ezinye izinamathiseli ezishisayo ezishisayo ezihlangabezana nezinye izinhloso ezikhethekile. Akunandaba noma hlobo luni lokunamathela okushisayo okukhona, bonke banenzuzo eyodwa eyisisekelo evamile, okungukuthi, bangaboshwa ngokupholisa nje. Kodwa-ke, ngoba belapha ngokushesha okukhulu, i-adhesion empofu ivame ukwenzeka lapho ukuncibilika okushisayo kuqinisa ngaphandle kokuthinta i-substrate emanzi, futhi amandla awo ancipha ngokushesha lapho izinga lokushisa lenyuka ngokushesha lapho izinga lokushisa lenyuka ngokushesha lapho izinga lokushisa liyanda lapho izinga lokushisa likhula ngokushesha lapho izinga lokushisa lenyuka ngokushesha lapho izinga lokushisa lenyuka ngokushesha lapho izinga lokushisa lenyuka ngokushesha lapho izinga lokushisa lenyuka ngokushesha lapho izinga lokushisa lenyuka ngokushesha lapho izinga lokushisa lenyuka lapho izinga lokushisa liyanda lapho izinga lokushisa lenyuka. Uma kwenziwa kahle, zingafaneleka kakhuluAmabhokisi okupakisha okuphelele we-BaklavaIzicelo. , kepha ayilungele ukusebenza okushisa kakhulu kokugcwalisa noma ukupakishwa kokubhaka.

Indlela ye-Roller Gluing. Indlela ilula, kepha umphumela ophelele awumpofu.

Indlela ye-nozzle coating.

I-glue eshisayo eshisiwe ibekwe kwi-tube yokugcina ye-glue 6, futhi ishubhu yokugcina le-glue lixhunyiwe ku-nozzle 7; I-carton ehlanganisiwe eyi-10 ithunyelwa esimweni se-glue coating ngebhande elihambisanayo 9, kanti ama-nozzle afaka i-glue ecindezelwe ukuze wakhe i-glue eceptipheni lebhokisi. Ungqimba lwe-glue 8 lugoqiwe, lucindezelwe futhi lupholile ukuqeda isibopho. Njengoba i-nozzle ayihlali i-carton ne-glue kufafazwa ngaphansi kwengcindezi, ijubane lokuhlanganisa lishesha futhi. Phakathi kwezindlela ezahlukahlukene zokubopha, kusetshenziswa kabanzi.

Indlela yokuhlangana yeglue.

I-glue eshisayo eshisayo igcinwa kuthangi lokugcina le-glue 11. Ingaphezulu elihlanganiswe ne-glue ibhokisi eliphansi 13 liya phansi bese lifakwa ethafeni eliphansi le-glue lihamba ngethangi elingenalutho. I-glue isetshenziswa ethangeni le-glue, bese lifinyelela phezulu ngokugoqa, ngokucindezela nokupholisa ukuqeda ukubopha isibopho. Iplate ethosiwe ye-glue Le ndlela isetshenziselwa kakhulu ukunamathisela amabhokisi.
