Push-in Mechanism Dynamic Height Adjustment for Box Packing Speed

The push-in plate is designed to dynamically change its lower edge height during the operation cycle. The lifting/lowering mechanism raises the push-in plate to a higher position during the return stroke to clear articles, then lowers it to the original position for pushing. This dynamic adjustment allows the system to maintain reliable pushing action while enabling faster cycle times, thus resolving the contradiction between pushing reliability and production line efficiency.

Instead of maintaining a fixed low position, the push-in plate dynamically adjusts its height. During the return stroke, the lifting/lowering mechanism raises the push-in plate to prevent interference with the next article. This dynamic height adjustment resolves the contradiction by temporarily increasing device complexity through the lifting mechanism to achieve smooth article movement, while maintaining structural simplicity during the actual pushing operation.

The system uses dynamic height adjustment rather than a permanently increased push-in plate height. The lifting/lowering mechanism temporarily raises the plate only during the return stroke when high clearance is needed, then lowers it to the optimal pushing position for high-speed operation. This temporal separation of functions resolves the contradiction by providing high clearance only when necessary, maintaining push-in speed during the critical pushing phase.

The lifting/lowering mechanism performs preliminary action by raising the push-in plate during the return stroke before the next article arrives. This preparatory height adjustment prevents future interference and eliminates waiting time. By anticipating and preventing potential hindrances in advance, the system can maintain faster operating speeds without creating bottlenecks, thus improving production line efficiency while minimizing loss of time.
