Description

Technical Field

[0001] This utility model relates to a sanitary napkin production line, and in particular to an adhesive strip cutting mechanism with adjustable adhesive strip position. Background Technology

[0002] A single sanitary napkin typically consists of a layer of wrapping paper with a tape attached to one end for secure fastening. During production, there are usually two folding processes: one folds one side of the sanitary napkin 180°, and the other folds the other side 180°, creating a triple-fold structure. Finally, a tape-cutting mechanism cuts the roll of tape and attaches it to the sanitary napkin. The tape's position differs depending on whether the left side is folded first, followed by the right side, or vice versa. Furthermore, the tape's position also varies depending on the size of the sanitary napkin. Currently, the conventional approach is to use a separate tape-cutting mechanism for each tape's position, requiring frequent changes based on the tape's location – a cumbersome process. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, this utility model provides an adhesive cutting mechanism with adjustable adhesive position.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] An adjustable adhesive tape slitting mechanism includes a mounting bracket, a slide rail on the mounting bracket, a mounting seat on the slide rail that can be adjusted in position perpendicular to the production line transport direction, a connecting seat on the mounting seat, an adhesive tape transport mechanism on the connecting seat, a pull roller for pulling the adhesive tape and a cutting roller for slitting the adhesive tape are mounted on the mounting seat at the rear end of the transport mechanism.

[0006] A rotating seat is mounted on the mounting bracket, and an adjusting shaft is rotatably mounted on the rotating seat. The end of the adjusting shaft is provided with an external thread, and the mounting bracket is provided with an internal thread hole corresponding to the external thread. The end of the adjusting shaft is threaded into the internal thread hole.

[0007] The rotating seat is provided with a "U" shaped groove, and the adjusting shaft is provided with an annular groove corresponding to the "U" shaped groove, and the annular groove is embedded in the "U" shaped groove.

[0008] The end of the adjusting shaft away from the external thread is provided with an internal hexagonal hole, and the end of the adjusting shaft away from the external thread is symmetrically provided with a platform structure that facilitates clamping with a wrench.

[0009] The mounting bracket is symmetrically provided with mounting parts for fixing on the production line. Each mounting part has a vertically elongated hole. Below the mounting part is an adjustment seat for mounting on the production line. The adjustment seat is equipped with an adjustment screw, the upper end of which abuts against the bottom of the mounting part.

[0010] The mounting base is equipped with a first motor for driving the cutter roller to rotate, a second motor for driving the traction roller to rotate, and a third motor for driving the transport mechanism to rotate.

[0011] The beneficial effects of this utility model are as follows: A slide rail is provided on the mounting bracket, and an adjustable mounting seat is installed on the slide rail, perpendicular to the production line transport direction. A connecting seat is installed on the mounting seat, and a conveying mechanism for adhesive tape is installed on the connecting seat. A pulling roller for pulling the adhesive tape and a cutting roller for cutting the adhesive tape are installed at the rear end of the conveying mechanism on the mounting seat. Depending on the required position of the adhesive tape on the sanitary napkin, the mounting seat can be adjusted to move the entire structure, including the cutting roller, pulling roller, and conveying mechanism, which are involved in cutting the adhesive tape. This allows the model to adapt to different packaging direction folding sequence sequences and the production needs of sanitary napkins of different sizes, reducing equipment replacement and debugging time and improving production efficiency.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0019] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0020] The following describes some embodiments of the present invention with reference to the accompanying drawings.

[0021] Reference Figure 1-5 An adjustable adhesive strip cutting mechanism includes a mounting bracket 1, a slide rail 2 on the mounting bracket 1, a mounting seat 3 on the slide rail 2 that can be adjusted perpendicular to the production line transport direction, a connecting seat 4 on the mounting seat 3, and an adhesive strip transport mechanism 5 on the connecting seat 4. A pulling roller 6 for pulling the adhesive strip is mounted on the mounting seat 3 at the rear end of the transport mechanism 5, and a cutting roller 7 for cutting the adhesive strip (one end of the roll is removed, pulled and transported by the pulling roller 6 and the transport mechanism 5, and then cut by the cutting roller 7 to form a sheet structure; this process is existing technology). According to the position where the adhesive strip needs to be applied to the sanitary napkin, by adjusting the mounting seat 3, the cutting roller 7, pulling roller 6, transport mechanism 5, and other structures involved in adhesive strip cutting can be moved as a whole, making it suitable for different packaging direction folding steps and the production needs of sanitary napkins of different sizes, reducing equipment replacement and debugging time, and improving production efficiency.

[0022] A rotating seat 8 is mounted on the mounting bracket 1, and an adjusting shaft 9 is rotatably mounted on the rotating seat 8. The end of the adjusting shaft 9 is provided with an external thread, and the mounting seat 3 is provided with an internal thread hole 21 corresponding to the external thread. The end of the adjusting shaft 9 is threaded into the internal thread hole 21. When the adjusting shaft 9 is rotated, the mounting seat 3 can be driven to slide on the slide rail 2 through the thread structure, thereby realizing the function of adjusting the position of the sticker.

[0023] Furthermore, the rotating seat 8 is provided with a "U"-shaped groove 10, and the adjusting shaft 9 is provided with an annular groove 11 corresponding to the "U"-shaped groove 10. The annular groove 11 is embedded in the "U"-shaped groove 10, and the two side walls of the annular groove 11 are clamped to both sides of the rotating seat 8, thereby enabling the adjusting shaft 9 to move along the axis and preventing the adjusting shaft 9 from moving while the mounting seat 3 remains stationary when the adjusting shaft 9 is rotated.

[0024] In the first embodiment, the end of the adjusting shaft 9 away from the external thread is provided with an internal hexagonal hole 12, which facilitates the rotation of the adjusting shaft 9 using a tool.

[0025] In the first embodiment, a platform structure 13 is symmetrically provided at the end of the adjusting shaft 9 away from the external thread to facilitate clamping with a wrench.

[0026] The mounting bracket 1 is symmetrically provided with mounting parts 14 for fixing on the production line. The mounting parts 14 are provided with vertical elongated holes 15. Below the mounting parts 14, there is an adjustment seat 16 for mounting on the production line. The adjustment seat 16 is equipped with an adjustment screw 17. The upper end of the adjustment screw 17 abuts against the bottom of the mounting part 14. By rotating the adjustment screw 17, the horizontal height of the mounting part 14 can be adjusted so that the slide rail 2 on the mounting bracket 1 is at the same horizontal height, ensuring the accuracy of the sliding of the mounting seat 3.

[0027] The mounting base 3 is equipped with a first motor 18 for driving the cutter roller 7 to rotate, a second motor 19 for driving the traction roller 6 to rotate, and a third motor 20 for driving the transport mechanism 5 to rotate.

[0028] In this embodiment, the cutting roller 7, the pulling roller 6, the conveying mechanism 5, etc. are all components in the existing strip-slitting mechanism. The improvement of this application is that these components are installed on the mounting base 3 to achieve modularity. When the mounting base 3 detects movement, the structure participating in the slitting process is moved as a whole and synchronously.
