Background

CN101125612a discloses an intermittent star wheel bottle feeding device, which comprises an automatic bottle feeding component and a bottle feeding star wheel component connected with the automatic bottle feeding component, wherein the bottle feeding star wheel component comprises a bottle supporting track, a guard rail and a bottle poking star wheel driven to rotate by a transmission mechanism, the bottle supporting track and the guard rail are arranged on the bottle feeding side of the bottle poking star wheel, and the automatic bottle feeding component comprises a coaming and a bottle feeding net belt driven by the transmission mechanism. The bottle-feeding star wheel is characterized in that one or more groups of bottle-feeding poking teeth and circular arc sections are arranged on the bottle-feeding star wheel along the outer circumference, and the bottle-feeding poking teeth and the circular arc sections are alternately arranged.

In some bottle intermittent delivery mechanisms, a purely mechanical drive is used, such as by cams, gears, linkages, etc., to effect intermittent delivery.

Meanwhile, the pure mechanical structure cannot realize variable transmission beats and cannot meet the requirements of multiple production processes. Furthermore, the transmission structure of the pure machine is complex in structure, and is inconvenient to maintain.
