摘要： 为解决纠偏传输时纸塑复合袋易产生褶皱的问题，设计了一种磁力压紧纠偏装置。首先，综合利用磁压紧皮带、传送带和磁铁位置调整装置等零部件，完成了纸塑复合袋磁力压紧纠偏装置的结构设计，并根据纸塑复合袋的受力分析，建立了动态磁力压紧纠偏数学模型。然后，对纸塑复合袋磁力压紧纠偏装置进行有限元建模，并根据纸塑复合袋纠偏过程设置边界条件及接触参数，采用显示动力学分析方法对其动态纠偏过程进行仿真。接着，基于仿真结果，结合BP（back propagation，反向传播）神经网络和GA（genetic algorithm，遗传算法）（简称为BP-GA算法），建立了纸塑复合袋磁力压紧纠偏装置工艺参数优化模型。最后，通过相应的计算程序，实现了纸塑复合袋磁力压紧纠偏装置工艺参数的优化。结果表明：所设计的纸塑复合袋磁力压紧纠偏装置能较好地实现纠偏功能，可使纸塑复合袋在传输时产生的褶皱符合设计要求；纠偏时该装置的最优工艺参数为电磁铁磁力为7 N，左、右两侧皮带组件的间隙为476 mm，皮带组件与纸塑复合袋之间的动摩擦系数为0.25，实验结果与基于BP-GA算法的寻优结果较为一致。研究结果可为纸塑复合袋连续磁力纠偏的深入研究提供一定的参考。
Abstract: In order to solve the problem that the paper-plastic composite bag is easy to wrinkle during the correction transmission, a magnetic compression correction device was designed. Firstly, the structure of the magnetic compression correction device for paper-plastic composite bag was designed by comprehensively using the magnetic compaction belt, the conveyor belt and the magnet position adjustment device. According to the force analysis of the paper-plastic composite bag, a mathematical model of dynamic magnetic compression correction was established. Then, the finite element modeling of the magnetic compression correction device for paper-plastic composite bag was carried out. The boundary conditions and contact parameters were set according to the correction process of the paper-plastic composite bag, and the dynamic correction process was simulated by the explicit dynamics analysis method. Then, based on the simulation results, combined with BP (back propagation) neural network and GA (genetic algorithm) (referred to as BP-GA algorithm), a process parameter optimization model of the magnetic compression correction device for paper-plastic composite bag was established. Finally, the process parameters of the magnetic compression correction device for paper-plastic composite bag were optimized by the corresponding calculation programs. The results showed that the designed magnetic compression correction device for paper-plastic composite bag could realize the correction function, and could make the wrinkles of paper-plastic composite bags during the transmission meet design requirements; the optimal process parameters of the device during correction were as follows: the electromagnet magnetic force was 7 N, the gap between the left and right belt components was 476 mm, the dynamic friction coefficient between the belt components and the paper-plastic composite bag was 0.25, which was consistent with the optimization results based on the BP-GA algorithm. The research results can provide a reference for the further study of continuous magnetic correction of paper-plastic composite bags.
