The invention provides a
punching and deburring device for a
polyethylene resin film, and relates to the field of plastics. The
punching and deburring device for the
polyethylene resin film is used for conveying the
plastic film, and comprises a
workbench, wherein two traction rollers are arranged on the
workbench, and a support plate is arranged on the
workbench. According to the
punching and deburring device for the
polyethylene resin film, needle holes are formed in the workbench, steel needles are installed on a transverse plate, and electric push rods electrically drive the transverse plate to lift so that the steel needle can puncture the
plastic film, so that the
plastic film is punched; an
air pump, air bags, expanding rods and rubber bands are matched mutually, so that the overalldiameters of the steel needles are changed so as to punch the holes with different specifications, and the application range of the whole device is improved; a sliding strip, a spring, a
cutting block, a steel wire and a motor are matched mutually so that the
cutting block can move back and forth to smooth burrs generated by punching, so that the manual operation steps are reduced, and the laborcost is further reduced; and moreover, the burrs are processed while punching, so that the working efficiency is improved.
