Indlela yokukhetha inani lokukhiqiza lokusetshenziswa komshini wokupakisha ozenzakalelayo osheshayo

Njengoba amabhizinisi amaningi esebenzisa isivinini esikhulu ukupakisha okuzenzakalelayo umshini, enkambisweni yokupakisha ezenzakalelayo esheshayo yefilimu yokupakisha eguquguqukayo yezikhwama ezidabukile, ukuqhekeka, ukuhlukanisa, ukuvala ukushisa, izinkinga zekhwalithi yokuvala njengokungcola kancane kancane ziba isidingo sebhizinisi ukugxila ezinkingeni zenqubo yokulawula.

Amabhizinisi okupakisha aguquguqukayo ekukhiqizeni umshini wokupakisha ozenzakalelayo osheshayo usebenzisa i-reel yefilimu, kufanele anake okulandelayo:

1, umqulu wezidingo zezinto ezibonakalayo zefilimu

Ngenxa yokuthi isakhiwo semishini yokupakisha ezenzakalelayo esheshayo sihlukile kweminye imishini yokwenza izikhwama, ingcindezi yayo kumasondo amabili kuphela noma i-extrusion yokucindezela ukushisa kwento iphoqa omunye nomunye ukufeza ukuvalwa kokushisa, futhi akukho divayisi yokupholisa, ungqimba lwefilimu yokuphrinta lusedivayisini yokuvala ukushisa ethinta ngqo, ngaphandle kokuvikelwa kwendwangu yokuvikela. Ngakho-ke, ukuphrinta okusheshayo ukukhetha kwesendlalelo ngasinye kubaluleke kakhulu. Kufanele kuhambisane nezidingo ezikuthebula elingezansi:

2, ezinye izakhiwo kumele zihambisane nalokhu:

1) Ibhalansi yobukhulu befilimu

Ubukhulu befilimu yepulasitiki, ukujiya okumaphakathi kanye nokubekezelelana kobukhulu, ekuhlaziyeni kokugcina ukujiya kwe-diaphragm. Enqubweni yokukhiqiza kufanele kulawulwe ukufana kobukhulu befilimu, imikhiqizo ekhiqizwe ngenye indlela, akuyona umkhiqizo omuhle, umkhiqizo omuhle kufanele uqonde phezulu futhi uvundlile ufinyelele ukujiya kokulingana. Ngenxa yezinhlobo ezahlukene zefilimu encane, umphumela wokusetshenziswa uhlukile, ukujiya okumaphakathi kanye nokubekezelelana kobukhulu kuhlukile futhi. Mayelana nomehluko wobukhulu befilimu yokupakisha okuzenzakalelayo okuzenzakalelayo awudluli ku-15 um.

2) Izakhiwo ze-optical zefilimu encane

kubhekisela ku-haze, ukucaca, ukuhanjiswa kokukhanya kwamafilimu amancane.

Ngenxa yalokho, umqulu wefilimu wokukhetha izithasiselo ze-masterbatch kanye nobuningi bokwengeza unezidingo ezikhethekile kanye nokulawula, futhi unokucaca okuhle, kodwa futhi ufuna ukucabangela ubulili obuvulekile kanye nezinga elibushelelezi le-membrane, umthamo ovulekile wokugoqa ifilimu, ukugoqa, akwenzeki phakathi kokunamathela kwefilimu ngokomgomo. Uma inani eliningi kakhulu lizothinta umswakama wefilimu. Okubonakalayo ekukhanyeni, okujwayelekile kufanele kube ngaphezu kwama-92%.

3) I-coefficient yokungqubuzana

i-coefficient of friction ingahlukaniswa ibe yi-static friction kanye ne-dynamic friction system. Imikhiqizo ye-othomathikhi yokufaka i-drum, ngaphezu kwe-coefficient evamile yokuhlola i-friction, kufanele futhi ihlolwe ifilimu kanye ne-coefficient ye-friction yepuleti lensimbi engagqwali, ngenxa yongqimba lokuvala ukushisa lwefilimu yokufaka ezenzakalelayo ixhumana ngqo nomshini wokubumba ozenzakalelayo wokupakisha, i-coefficient ye-friction kufanele ibe ngaphansi kuka-0.4u.

4) Engeza umthamo

Ngokuvamile kufanele kulawulwe ngaphakathi kwama-300 ~ 500 PPM, ukuvuleka okuncane kakhulu kwethonya, njll. Umsebenzi we-membrane, okuningi kakhulu kuzobhubhisa amandla ahlanganisiwe. Futhi ukuvimbela izithasiselo enkambisweni yokusebenzisa inani elikhulu lokufuduka noma ukungena. Engeza umthamo ezingxenyeni ezingama-500 ~ 800 ngesigidi, kufanele usetshenziswe ngokucophelela, imithamo yokwengeza engaphezu kwama-800 PPM, ngokuvamile ungayisebenzisi.

5) Ulwelwesi oluhlanganisiwe lokufinyela okuhambisanayo nokungalingani

Ukufinyeza okungavumelani kufakwe ekushintsheni kwezinto zokugoba nokugoba, ukufinyeza okungavumelani kunokuvulwa kwesikhwama nokunye; Ukugoba ngaphakathi nangaphakathi; Noma nokunye Ukufinyeza Kwangaphandle & ngaphakathi; Izinhlobo ezimbili zezinhlobo, lesi simo sibonisa ukuthi ifilimu ehlanganisiwe ngaphezu kokufinyeza okuhambisanayo isakhona ngaphakathi kokufinyeza okungavumelani (Ukucindezeleka kokushisa noma ohlangothini oluhlukile kanye nosayizi wokufinyeza) 。 Ngakho-ke lapho uthenga ifilimu, kumele ibe sesimweni esifanayo, kuzo zonke izinhlobo zezinto ezihlanganisiwe zokushisa (Okushisayo nokunomswakama) Ukuhlolwa kokufinyeza okude nokuphambene, futhi umehluko walokhu okubili awukwazi ukwehluka kakhulu, cishe u-0.5% ungcono.

Lezi zinsimbi zokulinganisa amakhanda amaningi zenzelwe ukusebenza njengesiqondiso kubanikazi bamabhizinisi sendlela yokubona amathuba angaba khona okusungula izinto ezintsha kanye nendlela yokuzivumelanisa nobuchwepheshe obushintsha njalo banamuhla.

Ufuna inkampani ezophatha umshini wakho wokuhlola isisindo? Vakashela i-Smart Weighing And Packing Machine namuhla ukuze uthole ulwazi olwengeziwe.

Uma ufuna ukuthenga i-Smart Weigh Packaging Machinery Co., Ltd, kufanele uhlale ubeka ikhwalithi ngaphezu kwezindleko.

Isikali somshini wokukala siyisistimu esebenza kuzo zonke izinhlobo ekwazi ukugcina amakhulu ezinhlaka zenqubo yesikali samakhanda amaningi ukuze inikeze amaphrofayili wesikali ngokwezifiso zohlobo ngalunye lomshini wesikali kanye nokucushwa kwesikali samakhanda amaningi.

Kunezinzuzo eziningi ezihambisana ne-.
