我公(gong)司(si)生產的氣(qi)動(dong)(dong)(dong)式(shi)點(dian)(dian)斷(duan)機,主要應用于點(dian)(dian)斷(duan)精度(du)（±２０mm）要求不高的場合，與吹膜生產線連接(jie)做定(ding)長(chang)不停機點(dian)(dian)斷(duan)，塑料膜的長(chang)度(du)由旋轉編碼器和計數器來測量，給出(chu)動(dong)(dong)(dong)作信號，由氣(qi)動(dong)(dong)(dong)裝(zhuang)(zhuang)置(zhi)來完成點(dian)(dian)斷(duan)動(dong)(dong)(dong)作，氣(qi)缸(gang)加(jia)有(you)快速排(pai)氣(qi)裝(zhuang)(zhuang)置(zhi)，點(dian)(dian)斷(duan)動(dong)(dong)(dong)作（0.4s）。如有(you)需要還可以加(jia)裝(zhuang)(zhuang)打(da)孔、熱封等功能。本裝(zhuang)(zhuang)置(zhi)具有(you)很(hen)高的性價比，是各種連卷(juan)點(dian)(dian)斷(duan)的理想(xiang)選擇(ze)。

旋轉點斷式主要用于點斷精度高，適合多種卷取形式，本裝置主要有測量旋轉編碼器、伺服控制器及伺服電機組成。伺服電機帶動旋轉點斷刀動作，實現真正連續不停頓點斷。能針對不同規格的 薄膜薄膜進而調整，使用廣泛且使用靈活，降低制造成本又確保產品質量的薄膜點斷機。
