Although the existing semi-automatic packaging equipment can realize basic filling and sealing functions, there are still obvious deficiencies in packaging speed, precision and adaptability. In addition, frequent adjustment of mechanical structure is required when switching between multiple specifications of packaging, resulting in long downtime and seriously affecting productivity. In view of the above problems, it is urgent to develop a highly automated and flexible granular snack packaging equipment that can integrate bag taking, bag opening, accurate filling, heat sealing and finished product stacking functions.

[0003] Patent No. CN222876438U discloses an edge sealing device for a vertical snack packaging equipment, belonging to the technical field of packaging edge sealing.

The positioning assembly includes a positioning plate with a sliding slot in the middle. The outer wall of the positioning plate is fixedly assembled with a motor, and the output shaft of the motor is fixedly assembled with a turntable. The patent drives the turntable to rotate by the motor, thereby driving the moving rod to slide in the arc-shaped slot. Through the movement of the moving rod, the sliding rod is driven to move horizontally, thereby adjusting the distance between the two sliding rods, which can adapt to different sizes of packaging bags. Then, the top block is driven to move towards the positioning rod by the electric telescopic rod, and the positioning rod positions the snack packaging bag, so that it can not only adapt to different sizes of packaging bags, but also firmly position them, which is beneficial to improve the practicality and reliability of the device.
