[0002] Powder packaging bags are widely used in the chemical, building materials, food and other industries. After packaging, they usually need to go through the steps of boxing, shaping and palletizing for storage and transportation. In traditional production lines, these steps are often completed manually, which is inefficient and labor-intensive. Especially when dealing with large-scale production tasks, manual operation can easily lead to uneven stacking of packaging bags, thus affecting the space utilization of boxing and the stability of palletizing; in addition, manual operation may also cause product damage or stacking collapse due to fatigue or irregular operation, increasing production costs and safety risks.
