The application provides an automatic paper turning
machine, and relates to the technical field of paper turning machines.The automatic paper turning
machine comprises a
chassis, a side frame, a rotary table, a convex shaft, a groove body, a bearing, a motor I, a
hydraulic cylinder, a pressing frame and a groove.The side of the groove is provided with a lead screw, and the rotary table is provided with a motor II for driving the rotation of the lead screw.Two sliding sleeves are matched on the lead screw, and the movement directions of the two sliding sleeves are opposite.When the lead screw rotates, the two sliding sleeves move in opposite directions.Two connecting rods are arranged on the inside of each pressing frame, one end of the connecting rod is rotationally connected with the pressing frame, and the other end of the connecting rod is rotationally connected with the sliding sleeve.When the two sliding sleeves move towards or away from each other, the upper and lower pressing frames also move towards or away from each other.The automatic paper turning
machine can automatically complete the whole
process operation of clamping, tilting, turning, resetting and loosening of the paper material through the cooperative control of the motor I, the motor II and the
hydraulic cylinder, combined with the
limit switch and the
program control, without manual intervention, and the production efficiency is significantly improved.
