A clearance groove 4 is provided in the center of the workbench 2, and conveyor belt assemblies 5 are located on both sides, effectively supporting and accurately positioning the bags to prevent displacement or damage during transportation or sealing, thereby improving packaging quality.

[0029] The working principle of this utility model is as follows: The second adsorption component 14 removes the bottom of the bag from the bag rack 15 and moves it to the conveyor belt assembly 5. The two conveyor belt assemblies 5 and the second adsorption component 14 together support the movement of the bag. Then, the first adsorption component 10 moves to the top of the bag to adsorb, while the second adsorption component 14 keeps adsorbing the bottom of the bag. The first adsorption component 10 moves upward to open the bag. After the worker or robotic arm puts the product into the bag, the second cylinder 9 drives the folding plate 11 to press down to complete the bag filling. The worker can then seal the bag.

[0030] Understandably, the bottom of the bag holder 15 is provided with a notch 16 for the second adsorption component 14 to adsorb and remove the bag.

The longitudinal displacement component 18 and the bag storage rack 15 are located at opposite ends of the conveyor belt assembly 5. A flipping gripper mechanism 19 is mounted at the output end of the longitudinal displacement component 18. Specifically, after the product is bagged, it moves to the flipping gripper mechanism 19 via the conveyor belt assembly 5 and the second adsorption assembly 14. The flipping mechanism clamps and flips the entire bag by 90°, and the material is then discharged via the longitudinal displacement component 18.

[0032] The first lateral displacement component 7, the second lateral displacement component 12, and the longitudinal displacement component 18 can adopt solutions such as belt drive, linear motor drive, and lead screw rotation combined with lead screw nut displacement, which are existing technologies and will not be described in detail here.
