真空(kong)(kong)包裝機按照(zhao)抽氣方式不(bu)同會有內(nei)抽式和(he)外抽式兩種類(lei)型，它(ta)們都是(shi)由真空(kong)(kong)系(xi)統、抽充氣密(mi)封(feng)系(xi)統、熱壓封(feng)合(he)系(xi)統、電(dian)器(qi)控制(zhi)系(xi)統等組成。其中(zhong)(zhong)內(nei)抽式包裝機是(shi)有真空(kong)(kong)室(shi)的(de)，物品(pin)可(ke)以(yi)擺(bai)放在(zai)真空(kong)(kong)室(shi)里，合(he)上真空(kong)(kong)機的(de)真空(kong)(kong)室(shi)上蓋(gai)后，就(jiu)形成密(mi)閉(bi)的(de)空(kong)(kong)間(jian)，這樣就(jiu)可(ke)以(yi)進(jin)行抽真空(kong)(kong)工(gong)作(zuo)了，但是(shi)在(zai)工(gong)作(zuo)過程中(zhong)(zhong)，有時會出(chu)現真空(kong)(kong)蓋(gai)合(he)不(bu)上的(de)情況(kuang)
