[0002] White cardboard refers to single-layer or multi-layer paper made entirely from bleached chemical pulp and fully sized, suitable for printing and product packaging.

[0003] With the diversification of packaging, the appearance patterns of white cardboard are becoming increasingly rich and diverse. Among them, creasing and printing are essential processes in the processing of white cardboard. The creasing process generally involves installing concave and convex pressure rollers on a roller. The upper convex pressure roller squeezes the paper, while the lower concave pressure roller shapes and stabilizes the protruding parts of the paper, ensuring that the internal fiber structure of the paper is not damaged and significantly reducing paper fragility. The height is adjusted by multiple protrusions on the side of the adjustment plate, thereby adjusting the upper convex pressure roller and allowing paper of appropriate thickness to be placed for creasing as needed.

[0004] There is a multi-head impression roller in the prior art that can be switched to different impression heads for imprinting operations according to actual usage needs. However, the existing multi-head impression roller is inconvenient to adjust. The locking component needs to be removed before the impression roller can be rotated and adjusted. After adjusting to the appropriate impression head, the locking component is reinstalled. Utility Model Content

[0029] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0030] Reference Figures 1 to 4 As an embodiment of this utility model, a creasing mechanism for white cardboard 6 is provided, including a support frame 1, a pressure roller component 2, and an adjustment component 3. The pressure roller component 2 includes a support plate 21, a rotating shaft 22, and multiple impression rollers 23. The multiple impression rollers 23 are arranged around the rotating shaft 22 and rotatably connected to the support plate 21. The adjustment component 3 includes a one-way locking sleeve 31 and a rotating handle 32. The support frame 1 is provided with a mounting hole 11. The rotating shaft 22 is fixed to the support plate 21 and passes through the mounting hole 11 and is mounted on the support frame 1. A locking slot 12 is provided on one side of the mounting hole 11. The one-way locking sleeve 31 is fixedly sleeved on the rotating shaft 22 and located in the locking slot 12. The locking sleeve is rotatably connected to the locking slot 12 in one direction. The rotating handle 32 is fixed at the end position of the rotating shaft 22.

[0031] A locking slot 12 is provided on one side of the mounting hole 11. A one-way locking sleeve 31 is fixedly sleeved on the rotating shaft 22 and located in the locking slot 12. The locking sleeve is unidirectionally rotatably connected to the locking slot 12. The rotating handle 32 is fixed at the end of the rotating shaft 22. When it is necessary to adjust the position of the impression roller 23, the rotating handle 32 is rotated in the unlocking direction and simultaneously rotates the rotating shaft 22. After the rotating shaft 22 rotates, it drives the entire pressure roller component 2 to rotate, thus adjusting the position of the impression roller 23. After the position of the impression roller 23 is adjusted to the correct position, the rotating handle 32 is stopped. At this time, due to the locking effect of the one-way locking sleeve 31 and the locking slot 12, the pressure roller component 2 cannot rotate in the rolling direction, ensuring the normal operation of the pressure roller component 2. Compared with the existing method of adjusting the impression roller 23, the adjustment in this application can be completed directly by driving the rotating handle 32, which is quick and convenient.

[0032] Specifically, the one-way locking sleeve 31 includes a main body 311 and an elastic locking member 312. The side wall of the main body 311 is provided with a relief groove 313 for the elastic locking member 312 to deform. The side wall of the locking slot 12 is provided with a plurality of engaging protrusions 13, which form a circumference. The elastic locking member 312 can abut against the engaging protrusions 13. The elastic locking member 312 includes an elastic arm 3121 and a limiting protrusion 3122. One end of the elastic arm 3121 is connected to the main body 311, and the other end is connected to the limiting protrusion 3122. The limiting protrusion 3122 can be engaged between adjacent engaging protrusions 13. The elastic arm 3121, the limiting protrusion 3122, and the main body 311 are integrally formed parts. The elastic arm 3121 is made of an elastic alloy material. In this embodiment, there are two elastic locking members 312, which are respectively located at opposite positions on the main body 311. The two elastic locking members 312 make the locking effect of the rotating shaft 22 better.

[0033] Furthermore, the indentation mechanism also includes a tensioning assembly 4, which comprises a connecting sleeve 41 and a tension spring 42. A connecting frame 14 is provided on the support frame 1. The connecting sleeve 41 is fitted onto the end of the rotating shaft 22. One end of the tension spring 42 is fixed to the connecting frame 14, and the other end is connected to the side wall of the connecting sleeve 41. The tension spring 42 ensures a tight fit between the rotating shaft and the mounting hole 11, eliminating gaps.

[0034] Specifically, the connecting sleeve 41 includes a sleeve body 411 and a connecting block 412. The side wall of the sleeve body 411 is provided with an annular groove 4111, the cross-section of which is T-shaped. One end of the connecting block 412 is provided with a sliding ball head, which is embedded in the annular groove 4111. The connecting block 412 is slidably connected to the annular groove 4111 via the ball head. The other end of the tension spring 42 is connected to the connecting block 412. In this embodiment, multiple connecting frames 14 are arranged in a vertical row. The connecting frames 14 are located directly below the mounting hole 11. Both ends of the tension spring 42 are provided with hooks, which are used to hook onto the connecting block 412 and the connecting frame 14. By using multiple connecting frames 14, tension springs 42 of various sizes and lengths can be used for connection.

[0035] Furthermore, the creasing mechanism also includes a conveyor belt assembly 5, which includes a belt body 51 and a conveyor roller 52. The belt body 51 is fitted onto the conveyor roller 52, and white cardstock 6 is placed on the conveyor surface of the belt body 51. The impression roller 23 rolls and presses the white cardstock 6 below to realize the printing process.

[0036] In this embodiment, due to the locking effect of the one-way locking sleeve 31 and the locking slot 12, the pressure roller component 2 cannot rotate in the direction of roller pressing, ensuring the normal operation of the pressure roller component 2. Compared with the existing adjustment method of the impression roller 23, the adjustment in this application can be completed directly by driving the rotating handle 32, which is quick and convenient. By adopting the structure of multiple impression rollers 23 in this application, the positions of multiple impression rollers 23 can be changed to change the indentation and pattern without replacing the impression assembly, thus improving the printing efficiency.

[0037] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
