| 目的 为了避免给袋式挂面包装机装袋时的落料故障，设计筒状侧面折叠预制袋撑袋机构。方法 依据挂面充填技术要求及预制袋供送工艺路线，设计滑块摆杆撑袋机构；利用约束方程法建模，对撑袋机构进行设计；运用杆组法对撑袋机构进行运动学分析；借助Matlab编程，求解滑块摆杆撑袋机构尺度参数与运动学参数，绘制出摆杆的角位移、角速度、角加速度曲线。基于此设计加工撑袋机构，进行在线实验，并验证可靠性。结果 所设计滑块摆杆撑袋机构参数，连杆长度为89 mm，摆杆长度为115 mm，滑块偏距为122.5 mm，原动件滑块行程为10 mm，从动件摆杆摆角位移为5°；滑块位移与摆杆角位移满足线性关系，摆杆运动近似为匀加速。结论 在线实验验证该撑袋机构满足撑袋工艺要求，撑袋可靠性为94.6%，满足企业对全自动挂面包装机的要求，较好地解决了挂面包装落料故障。 |

| The work aims to design tubular side-folding bag-opening mechanism for prefabricated bags so as to avoid falling during the filling by bag-delivering machine for dried noodles. According to filling technology of dried noodles and bag delivering process, the rocker-slider bag-opening mechanism was designed. The constraint equation method was used to establish the model to design the bag-opening mechanism, and the kinematics analysis of the rocker-slider mechanism was carried out by assur-group method. Matlab programming was applied to solve the dimensional parameters and kinematic parameters of the rocker-slider mechanism, and the angular displacement, angular velocity and angular acceleration curve of the rocker were drawn. Based on this design, the bag-opening mechanism was processed and tested online and the reliability was also verified. The parameters of the rocker-slider mechanism were as follows: link length of 89 mm, rocker length of 115 mm, offset distance of 122.5 mm, driving link slider travel of 10 mm, and driven link rocker sway of 5°. The displacement of the slider and the angular displacement of the rocker satisfied a linear relationship. The angular acceleration of swing link was approximately uniform. Through online test, the bag-opening mechanism meets the technological requirements and the reliability of bag-opening mechanism reaches 94.6%, thus meeting the requirements on automatic bag-delivering machine for dried noodles by enterprises and solving the falling of dried noodle packages better. |
