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)(di)膜打孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)機包括(kuo)機架(jia)、繞制(zhi)(zhi)(zhi)框(kuang)(kuang)、開(kai)(kai)(kai)(kai)孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)襯板(ban)(ban)、開(kai)(kai)(kai)(kai)孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)模(mo)(mo)板(ban)(ban)和手(shou)動開(kai)(kai)(kai)(kai)孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)針，繞制(zhi)(zhi)(zhi)框(kuang)(kuang)通過轉(zhuan)(zhuan)軸(zhou)(zhou)地(di)(di)(di)支(zhi)承在(zai)(zai)機架(jia)上(shang)(shang)，在(zai)(zai)轉(zhuan)(zhuan)軸(zhou)(zhou)的(de)一端設(she)有轉(zhuan)(zhuan)動手(shou)輪，且轉(zhuan)(zhuan)軸(zhou)(zhou)與待加工地(di)(di)(di)膜的(de)安裝軸(zhou)(zhou)平行，繞制(zhi)(zhi)(zhi)框(kuang)(kuang)為長方形框(kuang)(kuang);開(kai)(kai)(kai)(kai)孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)襯板(ban)(ban)、開(kai)(kai)(kai)(kai)孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)模(mo)(mo)板(ban)(ban)均(jun)可(ke)(ke)轉(zhuan)(zhuan)動地(di)(di)(di)連接在(zai)(zai)機架(jia)的(de)上(shang)(shang)橫桿上(shang)(shang)。在(zai)(zai)開(kai)(kai)(kai)(kai)孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)模(mo)(mo)板(ban)(ban)上(shang)(shang)開(kai)(kai)(kai)(kai)有模(mo)(mo)孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)，在(zai)(zai)開(kai)(kai)(kai)(kai)孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)襯板(ban)(ban)上(shang)(shang)設(she)有導(dao)通孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)，在(zai)(zai)繞制(zhi)(zhi)(zhi)地(di)(di)(di)膜時(shi)，開(kai)(kai)(kai)(kai)孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)襯板(ban)(ban)和開(kai)(kai)(kai)(kai)孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)模(mo)(mo)板(ban)(ban)均(jun)偏移繞制(zhi)(zhi)(zhi)框(kuang)(kuang)，當地(di)(di)(di)膜繞制(zhi)(zhi)(zhi)結束(shu)，開(kai)(kai)(kai)(kai)孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)襯板(ban)(ban)和開(kai)(kai)(kai)(kai)孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)模(mo)(mo)板(ban)(ban)則置于繞制(zhi)(zhi)(zhi)框(kuang)(kuang)的(de)兩側(ce)，對(dui)繞制(zhi)(zhi)(zhi)的(de)地(di)(di)(di)膜開(kai)(kai)(kai)(kai)孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)時(shi)，防轉(zhuan)(zhuan)桿處于限(xian)轉(zhuan)(zhuan)位置，用手(shou)動開(kai)(kai)(kai)(kai)孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)針依據開(kai)(kai)(kai)(kai)孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)模(mo)(mo)板(ban)(ban)上(shang)(shang)的(de)模(mo)(mo)孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)逐一開(kai)(kai)(kai)(kai)孔(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)即可(ke)(ke);該機造價低廉，經濟實用。
