| 目的 设计一种新型中封制袋机构，实现烫压过程中塑料薄膜的连续进给，从而提高制袋效率。方法 应用圆压圆技术，设计一种中封制袋机构，利用SolidWorks建立关键机构的三维模型，对关键结构进行运动学分析，并采用电子凸轮曲线的方法对电机进行调速控制。结果 提出了中封制袋机的牵引、热封和剪裁的控制策略，通过改变牵引电机的速度，实现了在同一设备上对不同长度包装袋烫压的功能，完成了速度控制系统的硬件设计和软件编程，做出了样机，并进行了烫压实验，样机在0.5 s及更长的烫压时间下运行稳定，热封速度最快达到120袋/min，与市面上现有制袋机的制袋速度基本持平。结论 圆压圆中封制袋机实现了在烫压过程中薄膜的连续进给，验证了机构的合理性。 |

| The work aims to design a new type of bag-sealing mechanism and achieve the continuous feeding of plastic film in the process of hot pressing, so as to improve the bag-making efficiency. A bag-sealing mechanism was designed with cylindrical extruding cylinder technology. The 3D model of key mechanism was established with SolidWorks to analyze the kinematics of the key structure. Motor speed was controlled with electronic cam curve. The control strategies of traction, heat sealing and cutting of bag-sealing machine were put forward. By changing the speed of traction motor, the function of hot pressing of packaging bags of different lengths on the same equipment was realized, and the hardware design and software programming of speed control system were completed. The prototype was made and the pressing experiment was carried out. The prototype was stable at 0.5 s and longer hot pressing time. The heat sealing speed reached up to 120 pcs/min, which was substantially equal to the speed of the existing bag-making machine. The rotary bag-sealing machine can continuously feed film in hot pressing process, which verifies the rationality of the mechanism. |
