　　隨著市(shi)場上真空(kong)(kong)(kong)包(bao)(bao)裝機的(de)(de)廣泛使用(yong)，真空(kong)(kong)(kong)包(bao)(bao)裝機的(de)(de)操(cao)(cao)作人員的(de)(de)數量也在不斷(duan)增(zeng)多，對操(cao)(cao)作人員來說，了(le)解和掌握真空(kong)(kong)(kong)包(bao)(bao)裝機的(de)(de)運行(xing)規律和步驟，是很(hen)有必要的(de)(de)事情，因為熟悉(xi)的(de)(de)使用(yong)真空(kong)(kong)(kong)包(bao)(bao)裝機不僅能(neng)提高設(she)(she)備(bei)(bei)的(de)(de)效(xiao)率更能(neng)使設(she)(she)備(bei)(bei)使用(yong)更長久。

　　下面總結了(le)真空包(bao)裝機工作(zuo)的(de)四(si)大流(liu)程，以便讓操作(zuo)人(ren)員和(he)相關人(ren)員對此有個全(quan)面的(de)了(le)解。

　　一、對包(bao)裝(zhuang)物進行(xing)抽真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)包(bao)裝(zhuang)作(zuo)(zuo)業(ye)，使其達(da)到預定(ding)真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)度：將裝(zhuang)好包(bao)裝(zhuang)物的(de)(de)真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)包(bao)裝(zhuang)袋(dai)放入(ru)真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)室內(nei)，然后將真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)蓋合上，真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)泵開始(shi)工作(zuo)(zuo)，對真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)室進行(xing)抽氣，包(bao)裝(zhuang)袋(dai)內(nei)會(hui)同時(shi)達(da)到真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)狀態，真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)表(biao)指針上升，達(da)到預定(ding)的(de)(de)真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)度，在時(shi)間控制上由時(shi)間繼電器ISJ控制實現(xian)，抽氣完成后真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)泵自動(dong)停止(zhi)工作(zuo)(zuo)。在真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)包(bao)裝(zhuang)機作(zuo)(zuo)業(ye)的(de)(de)同時(shi)，二位三(san)通(tong)電磁閥IDT開始(shi)工作(zuo)(zuo)，氣囊保(bao)(bao)持真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)，熱(re)封壓架保(bao)(bao)持原位。

　　二、對(dui)包(bao)裝袋進(jin)行熱封口(kou)(kou)(kou)：電磁閥IDT斷開(kai)以后(hou)，外(wai)界(jie)大氣(qi)(qi)通過(guo)其上部進(jin)氣(qi)(qi)孔進(jin)入氣(qi)(qi)囊(nang)內部，利(li)用真(zhen)空室內部同氣(qi)(qi)囊(nang)之(zhi)間(jian)的(de)壓(ya)力差，氣(qi)(qi)囊(nang)充氣(qi)(qi)膨脹(zhang)，使熱封壓(ya)架頂起，壓(ya)緊袋口(kou)(kou)(kou)。同時熱封變壓(ya)器工(gong)作，開(kai)始封口(kou)(kou)(kou)。與此同時，時間(jian)繼(ji)電器ISJ開(kai)始工(gong)作，數秒后(hou)完成作業，熱封結(jie)束(shu)。

　　三、真空(kong)(kong)室進氣：二(er)(er)位(wei)(wei)(wei)二(er)(er)通電磁(ci)閥2DT打開，大(da)氣進入(ru)真空(kong)(kong)室，真空(kong)(kong)包(bao)裝(zhuang)機(ji)的(de)指針(zhen)回到零位(wei)(wei)(wei)，熱(re)封壓(ya)架依(yi)靠復(fu)位(wei)(wei)(wei)彈(dan)簧復(fu)位(wei)(wei)(wei)，真空(kong)(kong)包(bao)裝(zhuang)機(ji)上(shang)蓋打開。

　　四、循(xun)環作業：雙室(shi)真(zhen)空(kong)(kong)包裝(zhuang)機按照程序(xu)步驟把(ba)真(zhen)空(kong)(kong)室(shi)移至(zhi)另一(yi)真(zhen)空(kong)(kong)室(shi)，進入下一(yi)個工作循(xun)環，左右兩室(shi)交替工作，循(xun)環往復。
