AI Technical Summary
Existing packaging bag film slitting devices have difficulty ensuring the flatness of the film cutting position during the cutting process, and the debris and dust generated during cutting are difficult to remove effectively.
Steel balls are used as pressure-applying components. Pressure is applied to the film through gravity and air pressure to ensure the stability of the cutting position. Airflow is used to blow away debris and dust, enhancing the smoothness of the cut.
It improves the flatness of the film cutting position and effectively removes debris and dust during the cutting process, thus enhancing the cutting effect.
