The stability of the pallet stacking/feeder synchronous lifting system directly affects the stacking accuracy and equipment lifespan of the block production line. To address the challenge of multi-hydraulic cylinder synchronous control, this solution utilizes closed-loop feedback from high-precision displacement sensors and an adaptive PID algorithm to achieve a hydraulic cylinder lifting synchronization error of ≤±0.3mm. The system integrates a real-time eccentric load monitoring module, which dynamically adjusts the output force of each cylinder based on pressure sensor arrays, effectively suppressing jamming and structural deformation caused by eccentric loads. This technology is compatible with mainstream pallet stacking machines, supports one-click calibration and fault self-diagnosis, and can increase stacking qualification rates to 99.5% while reducing hydraulic system failure rates by 40%. It provides a highly reliable lifting control solution for automated block production lines.
