[0002] A printing press is a machine for printing words and images. An intaglio printing plate roller is a component on a printing press. Before leaving the factory, the compressive strength of the intaglio printing plate roller needs to be detected, and the plate roller needs to be limited and fixed during the detection.

[0003] According to a detection mechanism for an intaglio printing plate roller disclosed in a patent document with the existing publication number CN218974037U, it includes a base and a workbench. The workbench is fixedly installed at the center of the top of the base. First electric push rods are fixedly connected to both the left and right sides of the workbench. The telescopic end of the first electric push rod is fixedly connected to a connecting block. The top of the connecting block close to the first electric push rod is fixedly connected to a connecting plate. When this technical solution is used, the hydraulic cylinder is started, and then the hydraulic cylinder drives the pressing block to press the printing plate roller downward, thereby detecting the compressive performance of the printing plate roller. Through the above steps, the printing plate roller can be well fixed during the detection, avoiding the deviation of the printing plate roller during the detection. For the above technical solution, although the scheme realizes the limit fixation of the plate roller, the side of the plate roller cannot be limited during the limit fixation, and the damage of the two fixed points is easy to occur under extrusion, which is inconvenient in use.

In addition, when in use, the movable seat can be adjusted up and down according to the diameter of the plate roller, which is convenient for the rapid installation of plate rollers with different diameters.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please refer to Figures 1 to 4, the present utility model provides a technical solution: an automatic detection device for a printing plate cylinder, including a detection device body. The detection device body includes a base 1, on which a mounting seat 2 is welded. At the top of the mounting seat 2, a hydraulic mechanism 3 is fixed. The hydraulic mechanism 3 is a hydraulic push rod, which pushes a fixing frame 4 to move upward. The fixing frame 4 moves downward to squeeze and contact the plate cylinder through a rubber roller 6. One end of the hydraulic mechanism 3 is fixed with a fixing frame 4. On the side of the fixing frame 4, a power mechanism 5 is fixedly installed. The power mechanism 5 is a DC motor, which drives the rubber roller 6 to rotate. Later, the plate cylinder is driven to rotate by the rubber roller 6 for use. The power mechanism 5 is installed with a rubber roller 6, and the rubber roller 6 is rotatably installed between the fixing frames 4. On the base 1, a fixing seat 10 is welded. On the side of the fixing seat 10, a limiting column 11 is movably installed. On the side of the limiting column 11, a pressing plate 12 is movably installed. On the side of the base 1, a fixing plate 13 is fixed. On both the fixing plate 13 and the mounting seat 2, a displacement mechanism 14 is fixedly installed. One end of the displacement mechanism 14 is fixedly connected to the pressing plate 12. The displacement mechanism 14 is an electric push rod, which pushes the pressing plate 12 to squeeze the limiting column 11, and the limiting column 11 moves inward to complete the clamping and fixing of the plate cylinder.

[0024] In this embodiment, a movable seat 7 is movably installed on the base 1. Inside the movable seat 7, a movable block 8 is movably installed. An installation groove 9 is opened on the movable block 8. At the bottom of the movable block 8, a lifting mechanism 17 is fixed. The lifting mechanism 17 is fixedly installed inside the base 1. A positioning hole 15 is opened on the movable block 8. Inside the positioning hole 15, a positioning column 16 is movably installed. One end of the positioning column 16 is fixed to the bottom of the movable block 8. A plate cylinder is movably installed between the movable blocks 8. The lifting mechanism 17 is an electric push rod, which pushes the movable seat 7 to move up and down. The up and down movement of the movable seat 7 enables the two ends of plate cylinders with different diameters to be installed on the movable blocks 8.

[0025] In this embodiment, an opening 18 is opened inside the fixing seat 10. Inside the opening 18, a movable column 20 is movably installed. One end of the movable column 20 is welded to the limiting column 11. On the inner wall of the opening 18, a convex block 19 is fixed. One end of the movable column 20 is opened with a groove 21. Inside the groove 21, a displacement sensor 22 is fixedly installed. When the displacement sensor 22 senses the displacement of the limiting column 11, the monitored data is transmitted to an external device. On the side of the opening 18, a limiting groove 23 is opened. Inside the limiting groove 23, a limiting block 24 is movably installed. One end of the limiting block 24 is welded to the movable column 20. Between the limiting block 24 and the limiting groove 23, a support mechanism 25 is fixedly installed. The support mechanism 25 is a support spring, which pushes the limiting block 24 to move inside the limiting groove 23, and the movement enables the movable column 20 to return to its original position for later use.

[0026] The device provides the required electrical energy for the electrical appliances inside the device through an external power supply. When using the device, first start the lifting mechanism 17 to adjust the height of the movable seat 7, and quickly adjust it according to the diameter of the plate cylinder. After the height of the movable seat 7 is adjusted, install the plate cylinder on the top of the fixed seat 10. Both ends of the plate cylinder are installed inside the installation groove 9 through the fixed columns. When the diameters of the fixed columns are different, move the movable block 8 upward to disassemble it. After disassembly, replace the installation groove 9 with different widths to cooperate with the fixed columns. The plate cylinder rotates inside the installation groove 9 through the fixed columns. After the plate cylinder is installed, the plate cylinder is detected according to the requirements of plate cylinder detection. When it is necessary to detect the flatness of the surface of the plate cylinder, the limit columns 11 are movably installed on both sides of the plate cylinder, and the hydraulic mechanism 3 is started to push the fixed frame 4 downward. After the fixed frame 4 moves downward, the rubber roller 6 contacts the top of the plate cylinder. During the detection, the power mechanism 5 drives the rubber roller 6 to rotate, and the rubber roller 6 drives the plate cylinder to rotate. When the plate cylinder rotates, when the plate cylinder deforms, the plate cylinder at the convex position squeezes the limit column 11, and the limit column 11 moves outward under the extrusion. After the limit column 11 moves outward, the displacement sensor 22 monitors the moving distance, and later transmits the data to an external device for analysis and processing to detect whether the plate cylinder deforms. When it is necessary to monitor the compressive strength of the plate cylinder, start the displacement mechanism 14 to push the extrusion plate 12 inward. The extrusion plate 12 pushes the limit column 11 to move inward at the same time. After the limit column 11 moves inward, it squeezes and limits both sides of the plate cylinder. After the squeezing and limiting, the rubber roller 6 stops rotating. Under the push of the hydraulic mechanism 3, the rubber roller 6 applies pressure to the plate cylinder, and the magnitude of the pressure is monitored by the pressure sensor at the position of the rubber roller 6, so as to detect the compressive strength of the plate cylinder, thus ensuring the long-term use of the plate cylinder in the later stage.
