真空(kong)(kong)(kong)包裝機(ji)按照(zhao)抽(chou)(chou)(chou)氣方式不同會有(you)(you)內抽(chou)(chou)(chou)式和外抽(chou)(chou)(chou)式兩種類型，它們都是由真空(kong)(kong)(kong)系統、抽(chou)(chou)(chou)充氣密封系統、熱壓封合系統、電器控制(zhi)系統等組成(cheng)。其中內抽(chou)(chou)(chou)式包裝機(ji)是有(you)(you)真空(kong)(kong)(kong)室的(de)，物品可以擺(bai)放在真空(kong)(kong)(kong)室里，合上真空(kong)(kong)(kong)機(ji)的(de)真空(kong)(kong)(kong)室上蓋后，就(jiu)形(xing)成(cheng)密閉的(de)空(kong)(kong)(kong)間，這樣就(jiu)可以進行抽(chou)(chou)(chou)真空(kong)(kong)(kong)工(gong)作了(le)，但(dan)是在工(gong)作過(guo)程中，有(you)(you)時會出現真空(kong)(kong)(kong)蓋合不上的(de)情況
