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)(di)膜打孔(kong)(kong)(kong)(kong)機(ji)包(bao)括機(ji)架(jia)、繞(rao)(rao)(rao)制(zhi)(zhi)(zhi)(zhi)框、開(kai)(kai)孔(kong)(kong)(kong)(kong)襯板(ban)(ban)(ban)(ban)、開(kai)(kai)孔(kong)(kong)(kong)(kong)模(mo)(mo)板(ban)(ban)(ban)(ban)和手(shou)動開(kai)(kai)孔(kong)(kong)(kong)(kong)針，繞(rao)(rao)(rao)制(zhi)(zhi)(zhi)(zhi)框通(tong)過轉軸(zhou)地(di)(di)支承(cheng)在(zai)機(ji)架(jia)上(shang)，在(zai)轉軸(zhou)的(de)一端(duan)設有(you)(you)轉動手(shou)輪，且轉軸(zhou)與待加工地(di)(di)膜的(de)安裝軸(zhou)平行，繞(rao)(rao)(rao)制(zhi)(zhi)(zhi)(zhi)框為長(chang)方形框;開(kai)(kai)孔(kong)(kong)(kong)(kong)襯板(ban)(ban)(ban)(ban)、開(kai)(kai)孔(kong)(kong)(kong)(kong)模(mo)(mo)板(ban)(ban)(ban)(ban)均(jun)可轉動地(di)(di)連接在(zai)機(ji)架(jia)的(de)上(shang)橫桿(gan)上(shang)。在(zai)開(kai)(kai)孔(kong)(kong)(kong)(kong)模(mo)(mo)板(ban)(ban)(ban)(ban)上(shang)開(kai)(kai)有(you)(you)模(mo)(mo)孔(kong)(kong)(kong)(kong)，在(zai)開(kai)(kai)孔(kong)(kong)(kong)(kong)襯板(ban)(ban)(ban)(ban)上(shang)設有(you)(you)導(dao)通(tong)孔(kong)(kong)(kong)(kong)，在(zai)繞(rao)(rao)(rao)制(zhi)(zhi)(zhi)(zhi)地(di)(di)膜時(shi)，開(kai)(kai)孔(kong)(kong)(kong)(kong)襯板(ban)(ban)(ban)(ban)和開(kai)(kai)孔(kong)(kong)(kong)(kong)模(mo)(mo)板(ban)(ban)(ban)(ban)均(jun)偏移繞(rao)(rao)(rao)制(zhi)(zhi)(zhi)(zhi)框，當地(di)(di)膜繞(rao)(rao)(rao)制(zhi)(zhi)(zhi)(zhi)結束(shu)，開(kai)(kai)孔(kong)(kong)(kong)(kong)襯板(ban)(ban)(ban)(ban)和開(kai)(kai)孔(kong)(kong)(kong)(kong)模(mo)(mo)板(ban)(ban)(ban)(ban)則(ze)置于繞(rao)(rao)(rao)制(zhi)(zhi)(zhi)(zhi)框的(de)兩側，對繞(rao)(rao)(rao)制(zhi)(zhi)(zhi)(zhi)的(de)地(di)(di)膜開(kai)(kai)孔(kong)(kong)(kong)(kong)時(shi)，防轉桿(gan)處于限轉位置，用手(shou)動開(kai)(kai)孔(kong)(kong)(kong)(kong)針依據開(kai)(kai)孔(kong)(kong)(kong)(kong)模(mo)(mo)板(ban)(ban)(ban)(ban)上(shang)的(de)模(mo)(mo)孔(kong)(kong)(kong)(kong)逐一開(kai)(kai)孔(kong)(kong)(kong)(kong)即可;該機(ji)造價低廉，經濟實(shi)用。
