全自動(dong)(dong)(dong)氣動(dong)(dong)(dong)開卷機由承載機架、脹軸、電動(dong)(dong)(dong)旋轉(zhuan)系統(tong)等裝置組成，主要是用來釋放卷料。4件(jian)缸(gang)徑100的氣缸(gang)通(tong)過(guo)伸縮桿帶動(dong)(dong)(dong)滑套前后(hou)運動(dong)(dong)(dong)，當(dang)(dang)滑套向(xiang)前運動(dong)(dong)(dong)時通(tong)過(guo)連(lian)板弧形(xing)縮小(xiao)，當(dang)(dang)滑套向(xiang)后(hou)運動(dong)(dong)(dong)時弧形(xing)撐撐開，這種弧形(xing)撐結構簡單、運動(dong)(dong)(dong)靈活，卷料保(bao)證(zheng)可靠地固(gu)定在脹軸上。
