吹膜機主要結構  

主要(yao)由擠出機、機頭、模(mo)頭、冷卻裝置(zhi)、穩泡架、人(ren)字(zi)板、牽引輥(gun)、卷取(qu)裝置(zhi)等組(zu)成。

吹膜機擠出機

擠(ji)出機(ji)主(zhu)要由螺桿、機(ji)筒(tong)加(jia)料斗(dou)，減速及驅動(dong)電(dian)(dian)(dian)(dian)機(ji)組(zu)成，驅動(dong)電(dian)(dian)(dian)(dian)機(ji)采用電(dian)(dian)(dian)(dian)磁(ci)調速電(dian)(dian)(dian)(dian)機(ji)（也(ye)可(ke)用變頻(pin)普通(tong)電(dian)(dian)(dian)(dian)機(ji)），通(tong)過皮帶傳(chuan)動(dong)帶動(dong)減速器使(shi)螺桿在(zai)機(ji)筒(tong)中作旋轉運動(dong)；使(shi)其料斗(dou)塑(su)料顆粒(li)在(zai)外部加(jia)熱的情況下熔(rong)融的塑(su)料經三通(tong)過濾從模(mo)頭模(mo)口擠(ji)來。

吹膜機模頭  

本機組選用先進的螺旋模頭結構，根據高壓、低壓、混合料、再生料聚乙烯材料的特殊性，綜合考慮，設計了螺旋角、退坡角、定型角長度、模口開度等主要技術參數，經多次對比試驗進行選優定型。
