Description

TECHNICAL FIELD

[0001] The present application relates to a four-station longitudinal conveying type high-speed packaging machine, belonging to the field of packaging machinery. BACKGROUND

[0002] Patent document CN202481326U discloses a simple bag forming automatic packaging machine, which realizes film bag packaging by setting up three stations of bag making, bag loading and mouth sealing and cooperating with the swing arm mechanism to horizontally and transversely convey empty bags and full bags. Although this packaging machine can achieve a packaging speed of 600 bags per hour, the swing arm mechanism needs to clamp the two sides of the material bag to horizontally move the material bag, which causes problems such as deformation, misplacement and opening of the bag mouth during the process of moving the material bag forward into the next process. When it is necessary to extract air in the bag before sealing the mouth, an air extraction mechanism needs to be added to the mouth sealing device. Since air extraction and sealing are performed at the same station, the action time of the mouth sealing station is prolonged, thereby reducing the overall running speed and packaging capacity of the packaging machine, and the packaging speed is generally lower than 400 bags per hour.
