Feeding and discharging mechanical arm synchronous lifting mechanism for automatic packaging machine

A feeding and discharging mechanical arm synchronous lifting mechanism for an automatic packaging machine is characterized by comprising a three-axis movement mechanism and a mechanical arm clamp which are installed on a main machine frame, and the three-axis movement mechanism drives the mechanical arm clamp to move between an upper die assembly and a lower die assembly. The three-axis movement mechanism comprises a vertical driving shaft fixedly installed on the main machine frame, the vertical driving shaft is connected with a vertical driving motor, and vertical driving gears are installed at the two ends of the vertical driving shaft. The sliding rail mechanism is installed on the main machine frame, the vertical sliding plate is installed on the main machine frame in a sliding mode through the sliding rail mechanism, and a rack is arranged on the vertical sliding plate and meshed with the vertical driving gear. The automatic feeding and discharging device has the advantages that automatic feeding and au
