[0002] Automatic packaging machines are generally divided into semi-automatic packaging machines and fully automatic packaging machines. Automatic packaging machines are mainly used for automatic packaging of materials in the food, medicine, chemical and other industries and plant seeds. The materials can be in the form of granules, tablets, liquids, powders, pastes, etc. Automatic packaging machines have the functions of automatically completing metering, filling, bag making, sealing, cutting, conveying, printing production batch numbers, adding easy-to-cut edges, no-material warning, stirring, etc.

[0003] Automatic packaging machines for powder materials generally have two types: internal and external. External vacuuming means inserting a vacuum tube into the packaging bag to vacuumize. After reaching the preset vacuum degree, the bag mouth is heat-sealed by the sealing device. However, manual support of the bag mouth during operation poses a safety hazard and causes the position of the sealing line to the bag mouth to be inconsistent, and the labor intensity is relatively high.
