Problems solved by technology

[0002] An existing preservative film, especially a roll-type preservative film, was the first to tear off the preservative film to be used by hand tearing, but due to the characteristics of the preservative film itself, the preservative film is not easy to tear, resulting in the inconvenience
[0003] The more common cutting method now is to use a thin blade attached to the plastic wrap carton to cut the plastic wrap, but due to the interlocking relationship between the plastic wrap and the blade, it is not easy to use and it is not easy to cut a flat plastic wrap

Abstract

The invention relates to a preservative film cutting device which comprises a casing, a cutting unit, a drive unit and a starting unit. The casing comprises a side edge and two end points positioned at two ends of the side edge. The cutting unit comprises a cutter holder linearly displacing along the side edge of the casing, and a cutter positioned at the cutter holder and butted against the side edge of the casing. The drive unit is arranged at the casing and comprises a displacement piece connecting and driving the cutter holder to displace from one end point to the other end point, and a rotating piece driving the displacement piece. The starting unit drives the rotating piece to rotate, drives the displacement piece to move and then leads the cutter to linearly move. The invention drives the drive unit by using the starting unit and then pushes the cutting unit so as to conveniently cut a preservative film.

Description

technical field [0001] The invention relates to a cutting device, in particular to a cutting device for plastic wrap. Background technique [0002] An existing preservative film, especially a roll-type preservative film, was the first to tear off the preservative film to be used by hand tearing, but due to the characteristics of the preservative film itself, the preservative film is not easy to tear, resulting in the inconvenience. [0003] The more common cutting method now is to use a thin blade attached to the plastic wrap carton to cut the plastic wrap. However, due to the interlocking relationship between the plastic wrap and the blade, it is difficult to use and cut a flat plastic wrap. [0004] Therefore, a cutting device that can be used conveniently and can cut plastic wrap smoothly has always been a market demand. Contents of the invention [0005] The purpose of the present invention is to provide a plastic wrap cutting device that can cut the plastic wrap smo...
