[0002] Self-adhesive film is a functional film material whose core characteristic is that it can adhere to the surface of an object through its own adhesiveness without the need for additional glue or adhesive. Self-adhesive films are usually multi-layered, and in some production requirements, the self-adhesive film needs to be layered before subsequent processing. Existing self-adhesive film winding devices do not have a layering function, and the winding quality is poor, gradually failing to meet the increasing daily production demands. Announcement number CN221234911U discloses a self-adhesive film winding device, including a support frame. A mounting plate is fixedly installed at the top of the support frame. A servo motor is fixedly connected to the left side of the support frame. A bidirectional lead screw is fixedly mounted on the output shaft of the servo motor. A mounting ring engages with the surface of the bidirectional lead screw. A limit ring is fixedly connected to the bottom end of the mounting ring. A second servo motor is fixedly connected to the left side of the support frame. A winding roller is fixedly mounted on the output shaft of the second servo motor. A support plate is fixedly connected to the right side of the support frame. A spring assembly is fixedly connected to the top of the support plate. A compression cone is fixedly connected to the top of the spring assembly. Although the device can adapt to self-adhesive films of different widths, it cannot adapt to films of different thicknesses, and the winding quality is not high. Utility Model Content

[0032] Both the first adjusting seat 241 and the second adjusting seat 251 are provided with locking screws, which are used to fix the first adjusting seat 241 or the second adjusting seat 251.

[0033] In this embodiment, swing seats 221 are hinged to both the left and right sides of the frame 1. The two swing seats 221 are rotatably connected to a traction roller 22. Adjusting cylinders 27 are hinged to both the left and right sides of the frame 1. The piston rod of the adjusting cylinder 27 is hinged to the swing seats 221. A first drive motor 26 is provided on the frame 1. The first drive motor 26 is connected to a first reduction gearbox 261. The first reduction gearbox 261 is connected to another traction roller 22.

[0034] In this embodiment, swing frames 35 are respectively mounted on the left and right sides of the rubber roller 31. The two swing frames 35 are used to jointly support the air expansion shaft 32, and multiple third guide rollers 351 are connected between the two swing frames 35.

[0035] In this embodiment, a plurality of second guide rollers 36 are provided on the frame 1, and the plurality of second guide rollers 36 are respectively disposed between the rubber roller 31 and the traction roller 22.

[0036] In this embodiment, pressure arms 37 are hinged to the left and right sides of the frame 1, and pressure cylinders 371 are hinged to the left and right sides of the frame 1. The piston rod of a pressure cylinder 371 is hinged to a pressure arm 37. One side of the pressure arm 37 abuts against the top pressure air expansion shaft 32. A pressure groove 372 is opened on one side of the pressure arm 37. The pressure groove 372 is used to place the air expansion shaft 32. A connecting rod 373 is connected between the two pressure arms 37.

[0037] In this embodiment, a second drive motor 38 is provided on the frame 1, the second drive motor 38 is connected to a second reduction gearbox 381, and the second reduction gearbox 381 is connected to a rubber roller 31.

[0038] In this embodiment, the specific self-adhesive film winding process is as follows: First, adjust the positions of multiple first adjustment seats 241 according to the required width of the self-adhesive film to be divided. Specifically, loosen the locking screws of the corresponding first adjustment seat 241, and then move the first adjustment seat 241 to move each first adjustment seat 241 away from or closer to each other until each first adjustment seat 241 moves to the set position, and then retighten the locking screws. Similarly, loosen the locking screws of the corresponding second adjustment seat 251, and then move the second adjustment seat 251 to the set position, and then retighten the locking screws. In this way, the positions of each cutting blade 242 and each slitting blade 21 can be adjusted to adapt to cutting self-adhesive films of different widths.

[0039] At this time, a self-adhesive film with at least two layers is input. The self-adhesive film is guided and conveyed by multiple first guide rollers 23. During conveying, the self-adhesive film is cut into multiple strips by multiple slitting blades 242. Then, the self-adhesive film is divided into two layers by the slitting blade 21. The first drive motor 26 is then started, which drives one of the traction rollers 22 to rotate. In this way, the two layers of self-adhesive film are conveyed to the two winding mechanisms respectively by a pair of traction rollers 22 and multiple second guide rollers 36.

[0040] When the self-adhesive film after being layered enters the winding mechanism, an air shaft 32 is located in the two first mounting slots 33. The self-adhesive film is conveyed to the rubber roller 31. The second drive motor 38 drives the second reduction gearbox 381 to work. The second reduction gearbox 381 drives the rubber roller 31 to rotate. The rubber roller 31 generates friction, transferring the self-adhesive film from the rubber roller 31 to the air shaft 32 for winding.

[0041] As the air shaft 32 continuously winds up the self-adhesive film, and the self-adhesive film on the air shaft 32 abuts against the top pressure roller 31, the air shaft 32 leaves the first mounting groove 33 and then enters the second mounting groove 34. During the winding process, the air shaft 32 gradually rises in the second mounting groove 34. During this process, the piston rod of the pressure cylinder 371 gradually extends, causing the pressure arm 37 to swing to follow the movement of the air shaft 32. This allows the pressure arm 37 to continuously apply pressure to the air shaft 32, ensuring the winding effect of the air shaft 32, until the air shaft 32 moves to the end of the second mounting groove 34. Then, the corresponding film cutting mechanism is activated, such as cutting the self-adhesive film through a flying knife cylinder, thus completing the winding of the air shaft 32.

[0042] After winding is completed, a new air shaft 32 needs to be replaced into the first mounting slot 33. At this time, push the unwound air shaft 32 on the frame 1 until the air shaft 32 moves onto the two swing frames 35. Then push the two swing frames 35 forward to move the air shaft 32 into the first mounting slot 33, thus completing the semi-automatic winding of the air shaft 32.

[0043] In this process, by activating the adjusting cylinder 27, the piston rod of the adjusting cylinder 27 extends and retracts, causing the swing seat 221 to swing, thereby causing one traction roller 22 to move closer to or further away from the other traction roller 22, thus adjusting the distance between the two traction rollers 22 to accommodate self-adhesive films of different thicknesses.

[0044] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Any person skilled in the art can make more possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model. Therefore, all equivalent changes made based on the concept of this utility model without departing from the content of the technical solution of this utility model should be covered within the protection scope of this utility model.
