Bidirectional piston filling mechanism

According to the two-way piston filling mechanism, a first piston cylinder and a second piston cylinder are coaxially fixed to a rack, the space occupation in the radial direction of the piston cylinders under the condition that the multiple piston cylinders are arranged is reduced, and the first piston cylinder and the second piston cylinder are arranged between two sliding tables; the two sliding tables are used for driving the first piston cylinder and the second piston cylinder correspondingly, so that the moving directions of the two sliding tables are parallel to the arrangement direction of the axes of the piston cylinders, the moving part is prevented from moving in the radial direction of the piston cylinders, and the space occupied by the whole filling mechanism in the radial direction of the piston cylinders is further reduced. 本发明公开了一种双向活塞灌装机构，第一活塞缸和第二活塞缸同轴地固定在机架上，减小多个活塞缸布局情况下在活塞缸径向上的空间占用，第一活塞缸和第二活塞缸设置在两个滑台之间，两个滑台分别用于驱动第一活塞缸和第二活塞缸，使得两个滑台的运动方向平行于活塞缸的轴线的布置方向，避免运动部件在活塞缸的径向上运动，进一步减小整个灌装机构在活塞缸径向上的空间占用。
