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(mo)(mo)打(da)孔(kong)(kong)機包括機架、繞制(zhi)(zhi)框、開(kai)(kai)孔(kong)(kong)襯(chen)板(ban)(ban)(ban)、開(kai)(kai)孔(kong)(kong)模(mo)(mo)(mo)板(ban)(ban)(ban)和手動(dong)開(kai)(kai)孔(kong)(kong)針，繞制(zhi)(zhi)框通(tong)過(guo)轉(zhuan)(zhuan)(zhuan)(zhuan)軸地(di)支承在機架上，在轉(zhuan)(zhuan)(zhuan)(zhuan)軸的(de)(de)一端設有轉(zhuan)(zhuan)(zhuan)(zhuan)動(dong)手輪(lun)，且轉(zhuan)(zhuan)(zhuan)(zhuan)軸與(yu)待加工(gong)地(di)膜(mo)(mo)的(de)(de)安裝軸平行，繞制(zhi)(zhi)框為長(chang)方形框;開(kai)(kai)孔(kong)(kong)襯(chen)板(ban)(ban)(ban)、開(kai)(kai)孔(kong)(kong)模(mo)(mo)(mo)板(ban)(ban)(ban)均可轉(zhuan)(zhuan)(zhuan)(zhuan)動(dong)地(di)連接在機架的(de)(de)上橫桿上。在開(kai)(kai)孔(kong)(kong)模(mo)(mo)(mo)板(ban)(ban)(ban)上開(kai)(kai)有模(mo)(mo)(mo)孔(kong)(kong)，在開(kai)(kai)孔(kong)(kong)襯(chen)板(ban)(ban)(ban)上設有導(dao)通(tong)孔(kong)(kong)，在繞制(zhi)(zhi)地(di)膜(mo)(mo)時(shi)，開(kai)(kai)孔(kong)(kong)襯(chen)板(ban)(ban)(ban)和開(kai)(kai)孔(kong)(kong)模(mo)(mo)(mo)板(ban)(ban)(ban)均偏移繞制(zhi)(zhi)框，當地(di)膜(mo)(mo)繞制(zhi)(zhi)結束，開(kai)(kai)孔(kong)(kong)襯(chen)板(ban)(ban)(ban)和開(kai)(kai)孔(kong)(kong)模(mo)(mo)(mo)板(ban)(ban)(ban)則置(zhi)于繞制(zhi)(zhi)框的(de)(de)兩側，對(dui)繞制(zhi)(zhi)的(de)(de)地(di)膜(mo)(mo)開(kai)(kai)孔(kong)(kong)時(shi)，防轉(zhuan)(zhuan)(zhuan)(zhuan)桿處(chu)于限轉(zhuan)(zhuan)(zhuan)(zhuan)位(wei)置(zhi)，用(yong)手動(dong)開(kai)(kai)孔(kong)(kong)針依(yi)據開(kai)(kai)孔(kong)(kong)模(mo)(mo)(mo)板(ban)(ban)(ban)上的(de)(de)模(mo)(mo)(mo)孔(kong)(kong)逐(zhu)一開(kai)(kai)孔(kong)(kong)即可;該機造價低廉，經濟實用(yong)。
