When the four straightening plates rotate to a certain position, they will squeeze the pallet stack, making it straightened neatly in the Y-axis direction perpendicular to the ground;

[0015] 3. By switching the oil circuit through the solenoid valve on the hydraulic station, the first-stage oil cylinder is kept in place, and the second-stage oil cylinder drives the second-stage connecting ring to move linearly, thereby driving the second-stage round rod to move linearly. This operation is beneficial to provide power for the straightening structure, thus providing power for the straightening plate and enabling it to complete the straightening work on the pallet stack;

[0016] 4. When the second-stage oil cylinder drives the second-stage round rod to move linearly, it will drive the second rotating plate to rotate on the fixed shaft, thereby driving the rotation of the second fixed plates on both sides, and further causing the two second-stage straightening rods to drive the second connecting plate and the second round shaft to rotate on the second mounting plate, thus driving the relative rotation of the two straightening plates. When the two straightening plates rotate to a certain position, they will squeeze the pallet stack, making it straightened neatly in the X-axis direction perpendicular to the ground.
