壓球機主機(ji)由(you)電(dian)(dian)磁(ci)調速(su)(su)(su)電(dian)(dian)機(ji)提供動(dong)(dong)(dong)力(li)，通(tong)過皮帶(dai)輪(lun)、圓柱(zhu)齒輪(lun)減(jian)速(su)(su)(su)機(ji)、銷聯軸(zhou)器傳動(dong)(dong)(dong)到(dao)主動(dong)(dong)(dong)軸(zhou)。壓(ya)球機(ji)主動(dong)(dong)(dong)軸(zhou)和從動(dong)(dong)(dong)軸(zhou)通(tong)過開式齒輪(lun)保證同步運(yun)轉(zhuan)。被動(dong)(dong)(dong)軸(zhou)承(cheng)座后(hou)面裝(zhuang)有液壓(ya)裝(zhuang)置(zhi)。螺(luo)旋進(jin)料裝(zhuang)置(zhi)由(you)電(dian)(dian)磁(ci)調速(su)(su)(su)電(dian)(dian)機(ji)驅動(dong)(dong)(dong)，通(tong)過皮帶(dai)輪(lun)和蝸桿減(jian)速(su)(su)(su)器帶(dai)動(dong)(dong)(dong)回轉(zhuan)，將被壓(ya)物料壓(ya)入主進(jin)料口。由(you)于電(dian)(dian)磁(ci)調速(su)(su)(su)電(dian)(dian)機(ji)的(de)恒轉(zhuan)矩特(te)性，當螺(luo)旋喂(wei)料機(ji)的(de)壓(ya)料量(liang)與主機(ji)所需的(de)物料量(liang)相等時，可(ke)保持(chi)恒定的(de)喂(wei)料壓(ya)力(li)，穩定顆粒(li)質量(liang)。喂(wei)料量(liang)過大，會造(zao)成喂(wei)料裝(zhuang)置(zhi)電(dian)(dian)氣過載(zai)；如(ru)果(guo)喂(wei)料量(liang)太少，則不會成球。因此，熟練的(de)操(cao)作技(ji)巧(qiao)是保證壓(ya)力(li)球正常(chang)工作的(de)重要條件(jian)。
