[0018] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings: Example 1

[0019] like Figure 1-5As shown, a sealing adjustment mechanism includes a frame 1. A film roll for feeding film is provided on one side of the frame 1. Along the film feeding direction, a film feeding assembly 2, a first film pulling assembly 3, a second film pulling assembly 4, and a cutter assembly 5 for cutting the film are sequentially arranged on the frame 1. A sealing mechanism 6 for sealing the film is movably arranged between the first film pulling assembly 3 and the second film pulling assembly 4. The sealing mechanism 6 is movably mounted on the frame 1 via a slide rail 7. An adjustment assembly 8 is provided on the frame 1 for driving the sealing mechanism 6 to move between the first film pulling assembly 3 and the second film pulling assembly 4. A film stopping assembly 22 is provided on the frame 1 to clamp and fix the heat-sealed film. The film stopping assembly 22 is located above the cutter assembly 5. After heat sealing, the film is clamped and fixed by the film stopping assembly 22 and cut by the cutter assembly 5. The position of the sealing mechanism 6 on the frame 1 can be easily adjusted by adjusting component 8, which allows for convenient adjustment of the required film length. This makes it easy to produce bags of various lengths, with a wide range of applications, strong versatility, and effective cost savings.

[0020] The sealing mechanism 6 includes a base 9, which is slidably mounted on the slide rail 7 via sliders 10 on both sides. A set of opposing sealing blades 11 is disposed within the base 9. A fixing seat 12 for supporting the film is fixedly disposed within the base 9. The fixing seat 12 has a notch 13 for heat-sealing the film, located between the two sealing blades 11. The adjusting assembly 8 includes a driving wheel 14 and a driven wheel 15 rotatably mounted on the frame 1. A synchronous belt 16 is fitted onto the driving wheel 14 and driven wheel 15. The base 9 is fixedly mounted on the synchronous belt 16 via a connecting plate 23 and reciprocates along the slide rail 7 with the synchronous belt 16. An adjusting power source 17, which is a motor, is fixedly disposed on the frame 1 to drive the driving wheel 14 to rotate. During heat sealing, the film moves on the fixing seat 12, and the opposing sealing blades 11 move towards the notch 13 until they abut against each other on both sides of the film, thus heat-sealing the film.

[0021] The fixed base 12 is equipped with an upper cooling component 18 and a lower cooling component 19 for blowing air to cool the notch 13. A heat-sealing power source 20, which is a cylinder, is fixedly mounted on the frame 1 to drive the sealing blade 11 towards the notch 13 on the fixed base 12. A cooling assembly 21 for cooling the heat-sealed film is located at the front end of the film moving in the fixed base 12. After the sealing blade 11 heat-seales the film, it moves away from the film, and the upper cooling component 18 and lower cooling component 19 blow air to cool the contact area between the sealing blade 11 and the film, allowing the film to detach smoothly from the sealing blade 11. The subsequent cooling assembly 21 further cools and lowers the temperature of the heat-sealed area of ​​the film. Example 2

[0022] The difference from Embodiment 1 is that the sealing blade 11 is provided in two sets, the notch 13 has two openings, and the upper cooling component 18 and lower cooling component 19 are provided in two sets. Each set of sealing blades 11 corresponds one-to-one with the notch 13, upper cooling component 18, and lower cooling component 19. During heat sealing, the film stops moving. After the first set of sealing blades 11 heat seals the film, it resets. By adjusting the power 17 to drive the sealing mechanism 6 to move, the second set of sealing blades 11 is positioned directly above the heat sealing area for a second heat seal. After the second heat seal is completed, the sealing blades 11 detach from the film, and the film continues to move to complete the heat sealing. Example 3

[0023] The difference from Example 2 is that, during the first heat sealing, the first set of sealing blades 11 heat seals the film and then resets. After the sealing mechanism 6 is accelerated by adjusting the power 17, the second set of sealing blades 11 is aligned with the heat sealing area for the second heat sealing. After the second heat sealing is completed, the sealing blades 11 are separated from the film. During the heat sealing process, the film is always in motion, and the sealing mechanism 6 moves synchronously with the film during the heat sealing process under the drive of the adjusting power 17. Example 4

[0024] The difference from Example 2 is that, during heat sealing, both sets of sealing blades 11 move simultaneously toward the film to heat seal the film.

[0025] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications to the specification derived therefrom are still within the protection scope of this utility model.
