[0002] At present, tobacco factories mainly rely on manual labor in a series of processes such as carton opening, carton bagging, tobacco packing, weighing, plastic bag sealing, and carton sealing. The economic benefits of tobacco factories depend on the output, so production efficiency is very important for tobacco factories. Manual carton opening, bagging, packing, and sealing have low technical content and are time-consuming and labor-intensive. The automatic tobacco bagging and sealing system is a process that replaces manual carton opening, bagging, packing, and sealing.

The bag support component of the existing automatic bag lifting and sealing machine generally adopts a method of sliding two support plates to opposite sides to drive the plastic bag mouth to open in a straight line. This opening method is simple, the resulting seal is large, which is not conducive to the layout of the space inside the equipment. It is only suitable for some packaging needs that do not require high bag sealing, and it is difficult to meet the bag sealing requirements of the automatic packaging system of formula tobacco.
