The short cover opening and closing unit comprises a sixth driving mechanism connected with the support, a seventh driving mechanism connected with the moving end of the sixth driving mechanism and an eighth driving mechanism fixed on the support. The moving end of the eighth driving mechanism is connected with a limiting piece, and the limiting piece is used for limiting the opened short cover under the driving of the eighth driving mechanism.

8. The full-automatic uncovering and covering device for old paper boxes according to claim 7, characterized in that, The sixth drive mechanism, the seventh drive mechanism and the eighth drive mechanism are symmetrically two groups, and are respectively used for opening and closing of two short covers.

9. A full-automatic method for opening and closing a lid of an old paper box, characterized in that, The old paper box full-automatic opening and closing cover device of any one of claims 1-7 comprises the following processes: The motor drives the paper box moving synchronous belt module, and the paper box moving synchronous belt module is connected with the paper box moving push rod through a support to drive the paper box moving push rod to transfer the paper box to the opening and closing cover station; The cylinder conveying line drives the paper box to contact with the reference baffle in the conveying direction, and then the output end of the first drive mechanism is extended to lift to make the first flexible suction assembly contact with the bottom of the paper box, and the vacuum generator is opened to fix the paper box through the vacuum suction force of the suction cup; After the paper box is fixed, the second drive mechanism is extended to make the second flexible suction assembly contact with the upper long cover of the paper box, and the long cover of the paper box is sucked through the vacuum suction force, and the second drive mechanism is actuated to pull up to make the long cover of the paper box pre-opened by an angle; After the long cover of the paper box is pre-opened and fixed by the angle, the third drive mechanism is actuated to move the flap turning rod fixed on the cylinder turret to the lower side position, and the fourth drive mechanism is translated to insert the flap turning rod into the pre-opened long cover of the paper box; After the flap turning rod is inserted into the long cover, the second flexible suction assembly stops sucking the cover of the paper box, the fifth drive mechanism is extended to press down through the fixed second limiting plate to make the cover of the paper box keep a gap with the suction cup, the synchronous belt module is reset together with the long cover pre-opening mechanism, and then the second limiting plate of the fifth drive mechanism is reset; After the resetting is completed, the third drive mechanism is actuated to turn the long cover of the paper box through the flap turning rod; The sixth drive mechanism is translated to move the third flexible suction assembly of the short cover to the upper side of the short cover of the paper box, the seventh drive mechanism is actuated to extend to make the third flexible suction assembly adhere to and suck the short cover of the paper box; The seventh drive mechanism is translated to reset, and the fixed frame rotating shaft of the third flexible suction assembly, the connecting rod of the sixth drive mechanism and the seventh drive mechanism together constitute a multi-link mechanism to open the short cover of the paper box, after the short cover of the paper box is opened, the eighth drive mechanism is actuated to limit the short cover of the paper box; The third flexible suction assembly stops sucking, the seventh drive mechanism is actuated to lift the connecting rod to the initial position, and the third flexible suction assembly is reset along the rotating shaft by relying on the eccentric weight; After the packing task is completed, the sixth drive mechanism is actuated to reset, the seventh drive mechanism is translated, the short cover is pushed to close by the support of the third flexible assembly, the seventh drive mechanism is pressed down to ensure that the short cover of the paper box is closed in place, the seventh drive mechanism is lifted to reset, the sixth drive mechanism is translated to reset, the third drive mechanism is actuated to close the long cover of the paper box by the flap turning rod, the fourth drive mechanism is translated to reset, the third drive mechanism is actuated to reset, the first flexible suction assembly stops sucking, and the first drive mechanism is reset to make the paper box fall on the cylinder conveying line.
