During the inspection, the intaglio cylinder needs to be rotated at a constant speed during the water-draining and inspection processes to drain the water in the intaglio cylinder completely. The operation of lifting and erecting the intaglio cylinder during the vertical lifting and transportation process is time-consuming and laborious, and the operation of rotating the intaglio cylinder during the inspection of the intaglio cylinder is clumsy. The above situation causes a large amount of waste of labor and materials for enterprises using printing equipment in the printing industry, and also brings unnecessary economic burdens to the enterprises.

[0018] A lifting motor 29 is fixedly arranged on the upper end surface of the lifting and placing inspection machine 2. The output shaft of the lifting motor 29 is meshed with the machine head support 21 through a worm and gear and a lead screw nut mechanism. The machine head support 21 is slidably connected to the lifting and placing inspection machine 2 through a vertical slide rail and slider group 28; after the lifting motor 29 rotates, the machine head support 21 can vertically move up and down horizontally.

[0019] A spline shaft is arranged between the machine head 27 and the machine head support 21. A lead screw nut is fixedly arranged at one end of the spline shaft close to the machine head 27, and a magnetic suction top head 22 is fixedly arranged at one end of the spline shaft close to the machine head support 21; one end of a feed servo motor 23 is fixedly connected to the machine head 27, and the output end of the feed servo motor 23 is connected to a lead screw, so that after the servo motor 23 rotates, it can control the horizontal movement of the spline shaft, and further enable the magnetic suction top head 22 to horizontally move.

[0020] A rotation reduction motor 24 is fixedly arranged on the machine head support 21; a support sleeve is arranged in the machine head support 21. The support sleeve is sleeved on the spline shaft and is key-connected to the spline shaft. A rotating gear is arranged on the support sleeve, and bearings are arranged on the outer peripheral surfaces at both ends of the support sleeve and are connected to the inner cavity of the machine head support 21 through the bearings; the rotating gear is connected to the rotation reduction motor 24; after the rotation reduction motor 24 rotates, it controls the rotation of the rotating gear, and further drives the spline shaft to rotate, and finally controls the rotation of the magnetic suction top head 22; when the spline shaft horizontally moves, it does not affect the fixed positions of the support sleeve and the rotating gear.

[0022] The working principle of the gravure cylinder horizontal and vertical inspection and water pouring mechanism is as follows:

[0023] The gravure cylinder 6 is initially placed on the transfer table 1. First, start the traveling motor 214, and move the lifting and placing inspection machine 2 to stop at the gravure loading position 100; then start the feed servo motor 23, so that the spline shaft horizontally moves and extends towards the outside of the machine head support 21, and insert the magnetic adsorption head 22 into the inner hole of the gravure cylinder 6 and tightly adhere to its end face. At this time, the magnetic adsorption head 22 is electrified, so that the gravure cylinder 6 is fixed on the magnetic adsorption head 22.

[0024] Start the lifting motor 29, the machine head 27 drives the gravure cylinder 6 to move vertically upward to the position set by the staff, and then start the traveling motor 214 to drive the lifting and placing inspection machine 2 and the gravure cylinder 6 to move horizontally to the vertical inspection position 200 together; start the turning motor 26 to drive the turning shaft on the machine head support 21 to drive the machine head 27 to turn 90 degrees, so as to make the gravure cylinder 6 stand upright and pour out the remaining water in the cavity of the gravure cylinder 6.

[0025] Then start the rotating reduction motor 24 to drive the gravure cylinder 6 to rotate, and drain the remaining water in the cavity of the gravure cylinder 6 by centrifugal force. At the same time, the staff inspects the outer surface of the gravure cylinder 6; after the inspection is completed, start the turning motor 26 to reverse again to drive the turning shaft on the machine head 27 to drive the machine head support 21 to turn 90 degrees to make the gravure cylinder 6 in a horizontal posture; start the lifting motor 29, the machine head support 21 drives the gravure cylinder 6 to move vertically upward to the set position, and then start the traveling motor 214 to drive the lifting and placing inspection machine 2 and the gravure cylinder 6 to move horizontally to the set position of the gravure cylinder unloading position 300. Start the feed servo motor 23 again, the spline groove continues to extend outwards, the magnetic adsorption head 22 drives the gravure cylinder 6 to move to the set position above the bracket 5, the lifting motor 29 is started, and drives the machine head 27 to drive the gravure cylinder 6 to move vertically downward to the set position to place the gravure cylinder 6 on the bracket 5, and then the magnetic adsorption head 22 is powered off to release the gravure cylinder 6, and the feed servo motor 23 reverses, and the spline shaft returns to the initial position.

[0026] After the work is completed, the lifting and placing inspection machine 2 moves away from the gravure cylinder unloading position 300, and then moves to the gravure cylinder loading position 100 again to grab the next gravure cylinder 6 for water pouring inspection and placing operation, and so on in a cycle.
