| Abstract: |
| Objective According to the production requirements of paper corner production line, this paper focused on designing of a flying shear type paper corner fixed-length cutting machine system with continuous feeding. Methods The principle of rotating flying shears was used, and a closed-loop servo control system was adopted to achieve "speed Position Dual Sync" in fixed-length shearing process of tracing paper corner. Results This flying shear type cutting machine could eliminate the pause time in the traditional fixed-length cutting process and greatly improve the production efficiency. Meanwhile, fixed-length cutting could be realized for materials with different thickness, different length and different material feeding speed. Conclusion Flying shear type paper corner fixed-length cutting machine has simple structure, convenient operation and low production cost, and is widely applicable for fixed-length cutting of a variety of products. |
