吹膜機主要結構  

主(zhu)要(yao)由擠出機、機頭、模頭、冷卻裝(zhuang)置、穩泡架、人字板、牽引輥、卷取裝(zhuang)置等組成。

吹膜機擠出機

擠出機主(zhu)要由螺(luo)桿、機筒(tong)加(jia)料斗(dou)，減(jian)速(su)及驅動(dong)(dong)(dong)電(dian)(dian)(dian)機組成，驅動(dong)(dong)(dong)電(dian)(dian)(dian)機采用(yong)(yong)電(dian)(dian)(dian)磁調(diao)速(su)電(dian)(dian)(dian)機（也(ye)可用(yong)(yong)變(bian)頻普通電(dian)(dian)(dian)機），通過(guo)皮帶傳動(dong)(dong)(dong)帶動(dong)(dong)(dong)減(jian)速(su)器使(shi)螺(luo)桿在機筒(tong)中(zhong)作旋(xuan)轉(zhuan)運動(dong)(dong)(dong)；使(shi)其料斗(dou)塑(su)料顆粒在外部加(jia)熱(re)的情況下熔融的塑(su)料經(jing)三通過(guo)濾從模(mo)頭模(mo)口擠來(lai)。

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。
