[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, a packaging film conveying device for a packaging machine includes: a base plate 20, which is rectangular in shape. A film feeding frame 21 is fixedly connected to the top of the rear wall of the base plate 20. The film feeding frame 21 is composed of a U-shaped plate and a rotating roller inside the opening. The wall of the roller of the film feeding frame 21 is wound with packaging film. The front end of the packaging film is connected to the packaging machine. This is existing technology and will not be described in detail here.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the anti-wrinkle structure is set on the top of the base plate 20 to prevent wrinkles during the conveying of the packaging film. The anti-wrinkle structure includes: a fixed frame 30, a follower roller 31, and a sorting plate 34. The fixed frames 30 are symmetrically fixedly connected to the top of the base plate 20. The follower roller 31 is rotatably connected between the symmetrical fixed frames 30. The sorting plate 34 is fixedly connected to the top of the base plate 20. The sorting plate 34 is located between the fixed frame 30 and the film placement frame 21. The top of the sorting plate 34 is flush with the top of the follower roller 31.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the frame 30 is a rectangular plate, and multiple sets of symmetrical frames 30 are evenly arranged on the top of the base plate 20. Each set of symmetrical frames 30 is separated by identical follower rollers 31. The follower rollers 31 are cylindrical, and their ends are connected to the side walls of the frame 30 via round blocks. The tidying plate 34 is V-shaped, with its opening facing the follower rollers 31. The top of the tidying plate 34 has rounded corners. The anti-wrinkle structure also includes a limiting plate 32, an inclined plate 33, and a fan 35. The limiting plate 32 is fixedly connected to the top of all frames 30 on each side, the inclined plate 33 is fixedly connected to the top of the base plate 20 between each group of adjacent follower rollers 31, and the fan 35 is fixedly connected to the top of the base plate 20. The limiting plate 32 is a V-shaped cross-section rod, and the openings of the symmetrical limiting plates 32 face each other. The inclined plate 33 is a rectangular plate, and the inclined plate 33 is placed obliquely on the top of the base plate 20. The positions of each inclined plate 33 are staggered. The fan 35 is fixedly connected to the top of the base plate 20 by a bracket installed on the side wall. The fan 35 is located above the sorting plate 34 and the follower roller 31. The air outlet at the bottom of the fan 35 faces downward. The front wall of the base plate 20 is provided with an adjustment structure, which includes a front frame 40, an adjustment shaft 41 and a front roller 42. The front frame 40 is symmetrically fixedly connected to both sides of the front wall of the base plate 20. The adjustment shaft 41 is set between the symmetrical front frames 40. The front roller 42 is rotatably connected to the wall of the adjustment shaft 41.

[0030] In practical use, the end of the packaging film on the wall of the film feeding rack 21 is first connected to the packaging machine. Then, as the packaging machine is used, the packaging film on the wall of the film feeding rack 21 is unwound. When the packaging film is unwound, the bottom will contact the top of the sorting plate 34, the top of the follower roller 31, and the top of the front roller 42. When the top of the sorting plate 34 contacts the bottom of the film, it will push away the wrinkles on the wall of the film with the inclined surface of the top of the sorting plate 34. The follower roller 31 will roll synchronously with the movement of the packaging film. The fan 35 will blow air onto the top of the packaging film to make the packaging film face down and adhere. The top of each inclined plate 33 will also contact the bottom of the packaging film. The wrinkles on the wall of the packaging film will be pushed away to both sides with the inclined plate 33.

[0031] In summary, by setting up an anti-wrinkle structure and using a bonding method to automatically remove wrinkles from the packaging film during unwinding and conveying, the packaging quality of the packaging machine is guaranteed.

[0032] like Figure 5 As shown, the front frame 40 is an L-shaped block, and a circular groove is provided on the side wall of the front frame 40. The adjusting shaft 41 is cylindrical, and a thread is provided on half of the arc surface of the adjusting shaft 41. The thread on the wall of the adjusting shaft 41 can be connected to the thread in the circular groove on the wall of the front frame 40. The front roller 42 is cylindrical and can rotate on the wall surface of the adjusting shaft 41. A disc is symmetrically fixedly connected to the arc surface of the adjusting shaft 41, and the front roller 42 is located between the symmetrical discs.

[0033] In actual use, the adjusting shaft 41 is rotated, and the adjusting shaft 41 will translate between the symmetrical front frames 40 due to the threads on its wall. The front roller 42 will translate synchronously, and the packaging film on the top of the front roller 42 will translate along with the front roller 42. The packaging film will always be located between the discs on the wall of the adjusting shaft 41.

[0034] In summary, by setting up an adjustment structure and utilizing the adjustable front roller 42, the offset of the packaging film during movement and conveying can be prevented from affecting the packaging of the packaging machine.

[0035] Working principle: First, the end of the packaging film on the wall of the film feeding rack 21 is connected to the packaging machine. Then, as the packaging machine is used, the packaging film on the wall of the film feeding rack 21 is unwound. When the packaging film is unwound, the bottom will contact the top of the sorting plate 34, the top of the follower roller 31, and the top of the front roller 42. When the top of the sorting plate 34 contacts the bottom of the film, it will push away the wrinkles on the wall of the film with the inclined surface of the top of the sorting plate 34. The follower roller 31 will roll synchronously with the movement of the packaging film. The fan 35 will blow air on the top of the packaging film to make the packaging film face down and adhere. The top of each inclined plate 33 will also contact the bottom of the packaging film, and the wrinkles on the wall of the packaging film will be pushed away to both sides with the inclined plate 33.
