Efficient, automatic and precise palletizing machine

The utility model relates to the technical field of automatic feeding and discharging in furniture production, and particularly discloses an efficient, automatic and accurate palletizing machine. Comprising a gear rack used for supporting, an overturning and aligning width positioning mechanism arranged on the gear rack, a feeding compression roller assembly installed on one side of the overturning and aligning width positioning mechanism and a servo long edge positioning mechanism arranged on the inner side of the overturning and aligning width positioning mechanism. The long edge positioning mechanism and the synchronous belt edge returning device are driven by the servo motor, so that the action is accurate and reliable, and the maintenance is convenient; a synchronous belt transmission mechanism is adopted in the synchronous belt edge-returning device and has the functions of low noise and accurate transmission ratio, a pneumatic device is adopted in the turnover mechanism, the speed is high, the structur
