The grasping mechanism includes a fixed frame, a moving disk, several groups of grasping arms, and a linear driving mechanism. The moving disk is located below the fixed frame. The linear driving mechanism drives several groups of grasping arms to grasp the empty bags. Several groups of grasping arms are arranged circumferentially along the moving disk. Each group of grasping arms includes a first hinge seat, a limiting rod, a driving rod, and a second hinge seat. The first hinge seat is installed on the moving disk.
