3. A self-response predictive maintenance method of a cartoning machine according to any one of claims 1-2, characterized in that, The method comprises the following steps: S1, the workers place the folded packaging boxes in the storage groove formed by the plurality of vertical columns (33), and then place the products to be packed in batches on the top of the feeding conveying belt (12), the feeding conveying belt (12) continuously transports the products in batches to the position of the discharging assembly (4), and the products move to the position of the maintaining assembly (5) and temporarily stop; S2, the gripper installed on the taking manipulator (2) takes the topmost packaging box and places it on the top of the discharging conveying belt (41), then the suction cup (43) starts to adsorb the bottom of the taken packaging box, then the taking manipulator (2) is reset and the packaging box is pulled, the taking of the packaging box is cancelled when the packaging box is pulled open, and the taking manipulator (2) is reset to take the next packaging box and continuously perform the above operation. S3, the discharge conveyor belt (41) to the open packaging box for conveying, when the packaging box is conveyed to the position of the maintenance assembly (5), the linear guide (52) starts and drives the sliding seat (53), the connecting block (54), the push block (55) synchronous displacement, the push block (55) will one batch of products to the position of the packaging box, this batch of products is pushed to the inside of the packaging box to complete the boxing; S4, due to the opening state of the packaging box can not be guaranteed, so part of the packaging box will appear re-folding situation, the support opening assembly (56) and the adjusting assembly (57) follow the push block (55) synchronous displacement, the adjusting rod (571) is inserted into the inside of the packaging box, and then the distance measuring sensor (579) responds to the state of the packaging box; S5, if the packaging box is in the folded state, the first cylinder (564) drives the sliding rail (561), the sliding rail (561) drives the adjusting rod (571) to move up and slide out from the inside of the limiting groove (578) along the arc part of the limiting groove (578), at this time the adjusting rod (571) is extruded on the outside wall of the sliding rail (561) sliding, so that the two adjusting rods (571) are away from each other, the side wall of the packaging box is opened; S6, then the piston rod of the second cylinder (577) is elongated to drive the sliding rod (576) to slide in the through groove (575), the sliding rod (576) drives one end of the second hinged rod (574) to slide in the groove (572), the other end of the second hinged rod (574) extrudes the first hinged rod (573), so that the angle between the second hinged rod (574) and the first hinged rod (573) changes, the height of the first hinged rod (573) increases when it is in the inside of the packaging box, which supports the height of the packaging box, so that the packaging box is opened, this way plays a predictive maintenance effect, which can guarantee that the packaging box will not be disordered when packaging products.
