AI Technical Summary
Traditional paper-binding cutting equipment often causes paper to warp and shift during cutting, affecting the cutting effect and potentially rendering the paper unusable.
A cutting device including a pressing component and a positioning mechanism was designed. The pressing rod is pressed tightly against the paper and the sliding inner rod squeezes the spring to prevent the paper from shifting. At the same time, the V-shaped pressing frame and positioning push block are used to position and adjust the paper to ensure cutting accuracy.
It effectively avoids paper misalignment, improves cutting results, reduces paper scrap rate, and lowers cutting costs.
