打孔機是現在人們使用比較多的一種紡織設備，因為用途比較廣泛，所以現在打孔機的使用越來越多。地膜打孔機眾多打孔機中的一種，在用途上與其他的打孔機有相應的區別。

地(di)膜打孔(kong)(kong)(kong)(kong)(kong)機(ji)(ji)(ji)包括(kuo)機(ji)(ji)(ji)架、繞(rao)制(zhi)框、開(kai)(kai)(kai)孔(kong)(kong)(kong)(kong)(kong)襯(chen)板(ban)(ban)(ban)、開(kai)(kai)(kai)孔(kong)(kong)(kong)(kong)(kong)模板(ban)(ban)(ban)和手(shou)動開(kai)(kai)(kai)孔(kong)(kong)(kong)(kong)(kong)針，繞(rao)制(zhi)框通過轉(zhuan)軸地(di)支承在(zai)(zai)機(ji)(ji)(ji)架上(shang)(shang)(shang)(shang)，在(zai)(zai)轉(zhuan)軸的一端設有轉(zhuan)動手(shou)輪，且轉(zhuan)軸與(yu)待加工地(di)膜的安裝軸平(ping)行(xing)，繞(rao)制(zhi)框為長方形框;開(kai)(kai)(kai)孔(kong)(kong)(kong)(kong)(kong)襯(chen)板(ban)(ban)(ban)、開(kai)(kai)(kai)孔(kong)(kong)(kong)(kong)(kong)模板(ban)(ban)(ban)均可轉(zhuan)動地(di)連接在(zai)(zai)機(ji)(ji)(ji)架的上(shang)(shang)(shang)(shang)橫桿(gan)上(shang)(shang)(shang)(shang)。在(zai)(zai)開(kai)(kai)(kai)孔(kong)(kong)(kong)(kong)(kong)模板(ban)(ban)(ban)上(shang)(shang)(shang)(shang)開(kai)(kai)(kai)有模孔(kong)(kong)(kong)(kong)(kong)，在(zai)(zai)開(kai)(kai)(kai)孔(kong)(kong)(kong)(kong)(kong)襯(chen)板(ban)(ban)(ban)上(shang)(shang)(shang)(shang)設有導通孔(kong)(kong)(kong)(kong)(kong)，在(zai)(zai)繞(rao)制(zhi)地(di)膜時(shi)，開(kai)(kai)(kai)孔(kong)(kong)(kong)(kong)(kong)襯(chen)板(ban)(ban)(ban)和開(kai)(kai)(kai)孔(kong)(kong)(kong)(kong)(kong)模板(ban)(ban)(ban)均偏移(yi)繞(rao)制(zhi)框，當地(di)膜繞(rao)制(zhi)結束，開(kai)(kai)(kai)孔(kong)(kong)(kong)(kong)(kong)襯(chen)板(ban)(ban)(ban)和開(kai)(kai)(kai)孔(kong)(kong)(kong)(kong)(kong)模板(ban)(ban)(ban)則置(zhi)(zhi)于(yu)繞(rao)制(zhi)框的兩側，對繞(rao)制(zhi)的地(di)膜開(kai)(kai)(kai)孔(kong)(kong)(kong)(kong)(kong)時(shi)，防轉(zhuan)桿(gan)處于(yu)限轉(zhuan)位置(zhi)(zhi)，用手(shou)動開(kai)(kai)(kai)孔(kong)(kong)(kong)(kong)(kong)針依據(ju)開(kai)(kai)(kai)孔(kong)(kong)(kong)(kong)(kong)模板(ban)(ban)(ban)上(shang)(shang)(shang)(shang)的模孔(kong)(kong)(kong)(kong)(kong)逐一開(kai)(kai)(kai)孔(kong)(kong)(kong)(kong)(kong)即(ji)可;該機(ji)(ji)(ji)造價低廉(lian)，經濟實用。
