Description

Technical Field

[0001] This utility model belongs to the field of paper processing technology, and in particular relates to a paper slitting device. Background Technology

[0002] Paper is a thin sheet material made from plant fibers through processes such as pulping, papermaking, and drying. It is mainly used for writing, printing, packaging, or artistic creation. Splitting is one of the important steps in paper processing, used to divide large rolls of paper into multiple smaller rolls. To facilitate the splitting of paper, a splitting device is generally used.

[0003] The existing patent announcement number CN221916685U discloses a wide-width paper online slitting and winding device, including a device box, and a slitting and winding mechanism is provided on one side inside the device box; the slitting and winding mechanism includes a first transition roller, which is installed inside the device box, and a fixed shell is fixedly connected inside the device box. A rotating roller is installed inside the fixed shell, and an online slitting knife is installed at the bottom of the rotating roller. A cutting blade liner roller is installed inside the device box near the bottom of the online slitting knife;

[0004] However, it still has the following drawbacks in practical use:

[0005] 1. The slitting and winding device described above conveys the paper body through the first transition roller, the cutter liner roller, the upper drive roller, the lower drive roller, the expansion roller, the second transition roller, and the winding adjustment roller, and winds the paper body through the winding adjustment roller. However, during use, it is not convenient to quickly remove the winding adjustment roller, which makes it inconvenient to quickly unload the slitting paper. Moreover, the entire equipment needs to be stopped when unloading, resulting in low working efficiency.

[0006] 2. The slitting and rewinding device described above uses the cooperation of an online slitting knife and a cutting roller to slit the paper body and complete the paper rewinding. However, during use, it is not convenient to polish the online slitting knife. Because the blade of the online slitting knife is not sharp, there are many burrs at the paper cutting point, which affects the quality of the rewound paper.

[0007] To address these issues, we provide a paper splitting device. Utility Model Content
