Description

Technical Field

[0001] The utility model relates to a packaging bag film edge positioning and adjusting device. Background Art

[0002] At present, in the production of packaging bags for food and condiments, the packaging bag film needs to go through multiple processes such as multiple long-side heat sealing, multiple short-side heat sealing, side punching, and packaging bag cutting before the packaging bag can be finally formed. Due to the numerous processes, the overall production line length is relatively long, even reaching more than 10 meters. Since multiple long-side heat sealing and multiple short-side heat sealing are all operated by a hot press, multiple downward pressures will cause the packaging bag to shake during transportation, which will cause the packaging bag film to shift in position during transportation, affecting the subsequent punching positioning and cutting positioning.
