Description

Technical Field

[0001] This utility model relates to the field of paper cutting technology, and in particular to a cutting system. Background Technology

[0002] Currently, to achieve efficient slitting of thin products such as paper, corresponding slitting machines are often used in conjunction with their production lines to quickly and accurately cut wide products into several narrower products. Existing Chinese patents, such as CN202320423019.1, provide cutting mechanisms suitable for slitting machines. These cutting mechanisms generally include an upper cutting device and a lower cutting device arranged adjacent to each other on the slitting machine frame. The upper cutting device includes several annular cutters, and the lower cutting device includes several positioning rings to ensure stable cutting of paper and other materials by the annular cutters as they pass through the positioning rings.

[0003] However, existing cutting mechanisms often have relatively fixed positions for the upper and lower cutting devices. In order to ensure the cutting effect, the annular cutter is often inserted into the axial side of the positioning ring. This makes it extremely inconvenient for workers to maintain the upper cutting device and also makes it difficult to adjust the distance between the annular cutter and the positioning ring.
