[0020] The adjusting mechanism includes a first mounting frame 5, an adjusting roll 6, a mounting cavity 7, a servo motor 8, a driving gear 9, a driven gear ring 10, a threaded sleeve 11, a threaded rod 12 and a limiting structure. The first mounting frame 5 is installed on the top end of the bottom plate 1. Inside the first mounting frame 5, an adjusting roll 6 is installed. At the middle position of the top end of the first mounting frame 5, a mounting cavity 7 is installed. On one side of the top end of the mounting cavity 7, a servo motor 8 is installed. On one side inside the mounting cavity 7, a driving gear 9 is installed. The output end of the servo motor 8 is connected to one end of the driving gear 9. On one side of the driving gear 9, a driven gear ring 10 is engaged. Inside the driven gear ring 10, a threaded sleeve 11 is installed. The threaded sleeve 11 is penetrated by a threaded rod 12. The bottom end of the threaded rod 12 extends to the inside of the first mounting frame 5. The bottom end of the threaded rod 12 is connected to the top end of the adjusting roll 6. When it is necessary to adjust the tension of the packaging bag, start the servo motor 8 to drive the driving gear 9 to rotate. Since the driving gear 9 and the driven gear ring 10 are engaged with each other, under the limitation of the limiting rail 13 and the limiting block 14, the driven gear ring 10 is used to drive the threaded sleeve 11 to rotate. Since the threaded sleeve 11 and the threaded rod 12 are in threaded connection, under the guiding of the guiding hole 15 and the guiding rod 16, the threaded sleeve 11 is used to drive the threaded rod 12 to move, and then drive the adjusting roll 6 to move, so as to adjust the tension of the packaging bag, so that the packaging bag is not easy to wrinkle during winding, so that the winding effect of the packaging bag is better, thus greatly improving the practicability of the device during use.

[0021] The limiting structure includes a limiting rail 13 and a limiting block 14. The limiting rail 13 is installed at the bottom end inside the mounting cavity 7. Inside the limiting rail 13, a limiting block 14 is arranged. One end of the limiting block 14 is connected to the outside of the threaded sleeve 11. During use, the mutual cooperation between the limiting rail 13 and the limiting block 14 can be used to limit the movement of the threaded sleeve 11, so that the movement of the threaded sleeve 11 is more stable.

During use, by the mutual cooperation between the guiding hole 15 and the guiding rod 16, the guiding treatment can be carried out on the adjusting roller 6 during movement, making the adjusting roller 6 more stable during movement.

[0023] The flattening mechanism includes a second mounting bracket 17, a fixed roller 18, a movable roller 19, a fixed cavity 20, a damper 21, a telescopic spring 22 and a movable rod 23. The second mounting bracket 17 is installed at the middle position of the top end of the bottom plate 1. A fixed roller 18 is installed below the inner side of the second mounting bracket 17. A movable roller 19 is arranged above the fixed roller 18. A fixed cavity 20 is installed at the top end inside the second mounting bracket 17. A damper 21 is installed at the top end inside the fixed cavity 20. A telescopic spring 22 is arranged on the outer side wall of the damper 21. The bottom end of the damper 21 is installed with a movable rod 23. The bottom end of the movable rod 23 extends to the outside of the fixed cavity 20. The bottom end of the movable rod 23 is connected to the top end of the movable roller 19. A plurality of the fixed cavities 20 are installed at the top end inside the second mounting bracket 17. The plurality of fixed cavities 20 are equally spaced at the top end inside the second mounting bracket 17. During use, the packaging bag is passed through between the fixed roller 18 and the movable roller 19. At this time, the fixed cavity 20 is affected by the elastic force, driving the movable rod 23 to move, and then driving the movable roller 19 to move. The packaging bag is flattened by the fixed roller 18 and the movable roller 19, making the effect of the packaging bag during winding better and making the packaging bag flatter during winding, thus greatly improving the comprehensiveness of the device during use.

[0024] Working principle: The staff first passes the packaging bag under the cutting knife 24, uses the cutting knife 24 to cut the packaging bag, then passes it between the two adjusting rollers 6, and then passes it between the fixed roller 18 and the movable roller 19. At this time, the fixed cavity 20 is affected by the elastic force, drives the movable rod 23 to move, and then drives the movable roller 19 to move, uses the fixed roller 18 and the movable roller 19 to flatten the packaging bag. Finally, the packaging bag passes through the dividing roller 3 and is wound around the outer wall of the winding roller 4, and the winding roller 4 is used to wind the packaging bag. When cutting and winding the packaging bag, when it is necessary to adjust the tension of the packaging bag, start the servo motor 8 to drive the driving gear 9 to rotate. Since the driving gear 9 meshes with the driven toothed ring 10, under the limitation of the limit rail 13 and the limit block 14, the driven toothed ring 10 is used to drive the threaded sleeve 11 to rotate. Since the threaded sleeve 11 is threadedly connected to the threaded rod 12, under the guidance of the guide hole 15 and the guide rod 16, the threaded sleeve 11 is used to drive the threaded rod 12 to move, and then drive the adjusting roller 6 to move to adjust the tension of the packaging bag.
