The movement description of the cartoning machine suction box workstation is as follows:
     Turning the handwheel, the turntable is transported clockwise. The four equal-divided planetary gears drive the ventilation shaft, and connect the suction cup base to the suction cup for circular motion. The symmetric two suction cup bases and the suction cup direction are consistent, and the opposite two suction cups are opposite in direction. When one of the suction cups is turned to the lowest point, confirm that the suction cup base is perpendicular to the plane of the machine, and then tighten the screw at the bottom of the suction cup. When it continues to rotate to the front 20 mm of the tray tray, read the encoder display value and input. This value is the inspiratory on time. While turning the handwheel to turn the suction cup to the farthest position, make sure that it is in full contact with the plane of the box. The carton is sucked out of the library, and the suction cup drives the carton to the open box station. Adjust the rotating bracket so that the paper box slightly collides with the adjusting screw, and slightly rubs against the open box, so that the paper box is slightly opened, which can be used to open the box. The suction cup continues to move, the carton enters the carton chain station at a reverse angle of 45°, and the left side of the carton will first touch the chain baffle, and the right side of the carton passes under the guard bar, at which time the carton opens in a parallelogram. . Confirm that the angle encoder displays the angle and enter the angle value as the suction cutoff time. At this point, the carton enters the carton chain and is fully extended by about 90°, then the carton enters the subsequent station with the carton chain, and the entire suction process is completed.
