[0031] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0032] Please refer to Figures 1-8This utility model provides a hypoallergenic breathable adhesive tape with a cutting structure, including an adhesive tape body 11, which is wound around an inner ring 1. A rectangular frame 13 is fitted on the inner ring 1 and the adhesive tape body 11. A pressing mechanism 2 is provided on one side of the rectangular frame 13 inside the inner ring 1, and a conversion mechanism 3 is provided on one side of the adhesive tape body 11 outside the adhesive tape body 11. A cutting blade 14 for cutting the adhesive tape body 11 is installed on the conversion mechanism 3.

[0033] The rectangular frame 13 is fitted onto the inner ring 1 and the adhesive tape body 11, providing a mounting base for the pressing mechanism 2 and the conversion mechanism 3. When the adhesive tape is needed, the appropriate length of adhesive tape is pulled out from the adhesive tape body 11, and then the cutting blade 14 on the conversion mechanism 3 is used to cut the adhesive tape. Compared with traditional hypoallergenic breathable adhesive tape, there is no need to find additional cutting tools when using it, which improves the convenience of use.

[0034] The pressing mechanism 2 includes a second pressure roller 21, which is rotatably mounted on the movable frame 24. Limiting grooves 131 are provided on the top and bottom inner walls of the rectangular frame 13. The movable frame 24 is slidably connected in the limiting grooves 131. A spring 23 and a guide rod 22 are fixedly connected to one side of the movable frame 24. The guide rod 22 slides through one side of the rectangular frame 13. The spring 23 is sleeved on the guide rod 22, and one end is fixedly connected to the side wall of the rectangular frame 13.

[0035] When the spring 23 is compressed, it applies a spring force to the movable frame 24 in the direction of the adhesive tape body 11. The movable frame 24 slides in the limiting groove 131, ensuring the stability of its movement. The second pressure roller 21 is rotatably mounted on the movable frame 24. Under the action of the spring 23, the second pressure roller 21 will press the adhesive tape body 11, ensuring that the cutting blade 14 on the other side presses the adhesive tape body 11, which facilitates the cutting operation.

[0036] The conversion mechanism 3 includes a rotating shaft 32, and a number of positioning protrusions 321 are provided on the outer peripheral surface of the rotating shaft 32. The rectangular frame 13 is provided with a mounting hole 132. The rotating shaft 32 is rotatably connected to the mounting hole 132, and the positioning protrusions 321 abut against the inner wall of the mounting hole 132.

[0037] The positioning protrusion 321 abuts against the inner wall of the mounting hole 132, so that the rotating shaft 32 can maintain a stable position after rotation.

[0038] The positioning protrusion 321 is provided with retaining rings 34 at both the upper and lower ends. The retaining rings 34 are sleeved on the rotating shaft 32. The bottom of the rotating shaft 32 is fixedly connected to the mounting block 33. One end of the mounting block 33 is fixedly installed with a knife holder 16, and the other end is rotatably installed with a first pressure roller 17. The cutting blade 14 is fixedly installed in the knife holder 16. The top of the rotating shaft 32 is fixedly connected to a handle 31. The two ends of the surface of the handle 31 are respectively provided with a first indicator groove 311 and a second indicator groove 312 corresponding to the positions of the cutting blade 14 and the first pressure roller 17.

[0039] By turning the handle 31, the rotating shaft 32 can be rotated, thereby causing the cutting blade 14 or the first pressure roller 17 on the mounting block 33 to rotate to the position of contact with the adhesive tape body 11. When it is necessary to pull out the adhesive tape, turn the handle 31 to make the first pressure roller 17 contact the adhesive tape, and the cutting blade 14 rotates into the protective strip 15 to avoid injury during the pulling out of the adhesive tape. When it is necessary to cut the adhesive tape, turn the handle 31 to make the cutting blade 14 contact the adhesive tape and cut the adhesive tape. The first indicator groove 311 and the second indicator groove 312 can help the user accurately judge the position of the cutting blade 14 and the first pressure roller 17.

[0040] The conversion mechanism 3 allows for easy switching between the two states of pulling and cutting the adhesive tape, simplifying operation and improving usability. Meanwhile, the first pressure roller 17 ensures smoother tape pulling and prevents the tape from getting stuck during the pulling process.

[0041] A protective strip 15 for protecting the cutting blade 14 is fixedly connected to the inner wall of the rectangular frame 13.

[0042] When the cutting blade 14 is not in use, the cutting blade 14 can be rotated into the two protective strips 15 by turning the handle 31. The protective strips 15 can block external objects from contacting the cutting blade 14, preventing the blade from being damaged, and also preventing the blade from accidentally cutting the user.

[0043] This improves product safety and durability, reduces the risk of blade damage, and extends product lifespan.

[0044] In summary, the working principle of the hypoallergenic breathable adhesive tape with a cut-out structure according to this utility model embodiment is as follows:

[0045] When using hypoallergenic breathable adhesive tape, the user first turns the handle 31 and, by observing the second indicator groove 312 on the handle 31, rotates the first pressure roller 17 to the position where it contacts the adhesive tape body 11. The cutting blade 14 rotates into the protective strip 15 to prevent injury during the pulling out of the adhesive tape. When the adhesive tape needs to be cut, the user turns the handle 31 and, by observing the first indicator groove 311, rotates the cutting blade 14 to the position where it contacts the adhesive tape body 11 to cut the adhesive tape. When the cutting blade 14 is not in use, the protective strip 15 protects it to prevent damage to the blade and accidental injury. Throughout the process, the pressing mechanism 2 ensures that the first pressure roller 17 and the cutting blade 14 are pressed against the adhesive tape body 11, improving the reliability of the operation. The switching mechanism 3 enables convenient switching between the two functions of pulling and cutting the adhesive tape.

[0046] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
