In actual use, the operator first starts the air pump on one side of the second limiting frame, allowing it to uniformly control and deliver airflow through the second limiting frame, the air distribution pipe on the side of the air pump, and the second air control valve seat, respectively. The first and second limit frames are controlled by the extension and retraction of the second telescopic airbags inside. The second telescopic airbags then drive the arc-shaped side seats and top seats inside the first and second limit frames to adjust and retract towards the center. The arc-shaped side seats are connected to the two sides of the plastic flexible packaging through the adhesive strips on the inner wall. The top seat is connected by the material-fixing arc groove on the inner wall to limit the filling of salt into the plastic flexible packaging. This ensures that the salt is fully and evenly filled inside the plastic flexible packaging, which guarantees better subsequent cutting operations and demonstrates the practicality of the equipment design.

[0017] This plastic flexible packaging cutting device, through its feeding rack, first limiting rack, cutting rack, cutting seat, first air control valve seat, first telescopic airbag, cutting blade, and heating strip, further improves the overall efficiency of the equipment. In daily use, operators can connect the cutting seats at both ends of the cutting rack to the air distribution pipes on both sides of the first limiting rack and the second air control valve seat via the internal first air control valve seat. This connection with the air control pump enables control operation. Then, the operator controls the first telescopic airbag inside the cutting seat to perform a telescopic docking operation from both ends of the cutting rack, aligning the cutting blades at one end of the two sets of first telescopic airbags at the center position for flexible packaging cutting. Simultaneously, the heating strip on the inner wall of the cutting blade provides a more stable sealing operation. The alternating control of the feeding rack and cutting rack enables efficient packaging of the salt material, demonstrating the comprehensiveness of the equipment design.

Limiting components are provided on both sides of the feeding rack 1, and a cutting component is provided at the bottom end of the feeding rack 1. Second telescopic airbags 13 are provided on the inner walls of the first limiting frames 2 and second limiting frames 3. An arc-shaped side seat 14 is movably connected to the inside of the second limiting frame 3 via the second telescopic airbag 13. An adhesive strip 15 is provided on the inner wall of the arc-shaped side seat 14. The first limiting frame 2... The inner wall is provided with a top seat 16, and the inner wall of the top seat 16 is provided with a material-fixing arc groove 17. The second telescopic airbag 13 then drives the arc-shaped side seat 14 and the top seat 16 inside the first limit frame 2 and the second limit frame 3 to perform a center-adaptive contraction adjustment operation. The arc-shaped side seat 14 is arc-shapedly covered with the two sides of the plastic soft packaging through the adhesive strip 15 on the inner wall. The top seat 16 performs the limiting cover operation when the plastic soft packaging is filled with salt through the material-fixing arc groove 17 on the inner wall.

[0027] The limiting assembly includes a second limiting frame 3, which is fixedly connected to both sides of the feeding rack 1. A control air pump 4 is installed on one side of the second limiting frame 3. The cutting assembly includes a cutting frame 5, which is fixedly connected to the bottom of the feeding rack 1. Cutting seats 6 are fixedly connected to both ends of the cutting frame 5. A first control air valve seat 7 is located at the center of the cutting seat 6. A first telescopic airbag 8 is installed inside the cutting seat 6. A cutting blade 9 is fixedly connected to one end of the first telescopic airbag 8. A heating strip 10 is installed on the inner wall of the cutting blade 9. The first limiting... Air distribution pipes 11 are provided on the sides of frame 2, second limiting frame 3 and cutting seat 6. The center of the first limiting frame 2 and the second limiting frame 3 is provided with a second air control valve seat 12 through the air distribution pipe 11. The cutting seats 6 at both ends of the cutting frame 5 are connected to the air distribution pipes 11 and the second air control valve seat 12 on both sides of the first limiting frame 2 through the internal first air control valve seat 7. The control operation is realized through the connection with the air control pump 4, and then the first telescopic airbag 8 inside the cutting seat 6 is controlled to perform the telescopic docking operation from both ends of the cutting frame 5.

[0028] Working principle: During use, the user first starts the air pump 4 on one side of the second limiting frame 3, so that it can uniformly control and deliver airflow through the air distribution pipe 11 and the second air control valve seat 12 on the side of the second limiting frame 3 and the air pump 4. This controls the extension and retraction of the second telescopic airbag 13 inside the first limiting frame 2 and the second limiting frame 3. The second telescopic airbag 13 then drives the arc-shaped side seat 14 and the top seat 16 inside the first limiting frame 2 and the second limiting frame 3 to adjust and retract towards the center. The arc-shaped side seat 14 is connected to both sides of the plastic soft packaging through the adhesive strip 15 on the inner wall. The top seat 16 is connected through the material fixing arc groove 17 on the inner wall to limit the filling of salt into the plastic soft packaging. The even distribution of the contents ensures better subsequent cutting. In daily use, the operator can connect the cutting seats 6 at both ends of the cutting frame 5 to the air distribution pipes 11 and the second air distribution valve seat 12 on both sides of the first limit frame 2 through the internal first air control valve seat 7. The operation is controlled by connecting to the air control pump 4. Then, the operator controls the first telescopic airbag 8 inside the cutting seat 6 to perform the telescopic docking operation from both ends of the cutting frame 5, docking the cutting blades 9 at one end of the two sets of first telescopic airbags 8 at the center position for soft packaging cutting. At the same time, the heating strip 10 on the inner wall of the cutting blade 9 can perform a more stable sealing operation during the cutting process. The alternating control of the feeding rack 1 and the cutting frame 5 achieves efficient packaging of salt. The above is the complete working principle of this utility model.
