Full-automatic top plate placing device of sheet paper packaging line

The invention provides a full-automatic top plate placing device of a sheet paper packaging line. The full-automatic top plate placing device of the sheet paper packaging line comprises a vertical lifting device, a vertical lifting driving device, a horizontal movement driving device, a rack component, a matched professional conveying device and a matched top plate storage device. According to thefull-automatic top plate placing device of the sheet paper packaging line, a four-edge rectification device is driven by a rodless cylinder to achieve rectification and alignment of a top cover plateand a paper stack; a gear is driven by a motor to drive a rack to move up and down to achieve rising and falling of a top plate adsorption device; belt wheels are driven by the motor to achieve transverse movement of the vertical lifting device in the horizontal direction through the traction of a synchronous belt; and the top cover plate is sucked by means of vacuum suction force generated by avacuum generator.
