| 目的 解决弹簧力矩偏小导致抓纸困难的问题。方法 在满足使用要求的前提下， 基于梯度优化算法以弹簧质量最小为优化目标， 对面巾纸包装机抓纸系统的弹簧丝直径、 中径和工作圈数进行改进设计。通过对抓纸系统进行受力分析， 得到活动板重力矩和优化前后的弹簧力矩。结果 优化后的弹簧丝直径、 中径和工作圈数分别增加了13.78%， 23.37%和25.28%； 优化后的弹簧力矩显著增加， 在活动板向上旋转10°后， 弹簧力矩开始大于活动板重力矩。结论 优化后的弹簧满足使用要求， 能够保证抓纸动作较为准确地完成。 |

| Objective To solve the paper clamping difficulty caused by the low spring torque. Methods In the premise of meeting the using requirements, the parameters of spring in the paper-clamping system of the towel packaging machine, including spring wire diameter, middle diameter and the number of spring effective coils, were optimized by gradient optimal algorithm. Through stress analysis of the paper-clamping system, the gravitational torque of the portable plate and the spring torque before and after optimization were obtained. Results After optimization, the spring wire diameter, the middle diameter and the number of spring effective coils were increased by 13.78%, 23.37% and 25.28%, respectively. The optimized spring torque increased significantly. When the portable plate rotated 10 degrees upwards, the optimized spring torque was higher than the gravitational torque of the portable plate. Conclusion The optimized helical spring met the requirements of paper clamping and could ensure the accurate completion of paper clamping. |
