Description

Technical Field

[0001] The utility model relates to the technical field of packaging films, in particular to a stable and efficient packaging film cutting device. Background Art

[0002] In the modern packaging industry, the cutting of packaging films is one of the key links in the packaging process. The Chinese patent with the authorization announcement number CN215968948U discloses a cutting device based on the processing of packaging films. Specifically, a push plate is placed on the top surface of the base, and the middle end of the back surface of the push plate is fixedly installed with the top surface of the second hydraulic rod. Workers place the whole packaging film on the top surface of the push plate, and the second hydraulic rod is used to push the push plate to send the packaging film to be directly below the cutting knife for cutting.

[0003] There are still some problems in the above patent. Since the specifications of the packaging films are large and small, when the packaging film is placed on the top surface of the push plate, the packaging film is not fixed. When the push plate is pushed by the second hydraulic rod, the packaging film is prone to roll, resulting in the packaging film shifting when it is directly below the cutting knife. As a result, when the cutting knife cuts the packaging film, the cut of the packaging film is oblique, damaging the packaging film. Therefore, there is an urgent need for a stable and efficient packaging film cutting device that can fix the packaging film to avoid damage to the packaging film by the cutting knife.
