[0003] In the gravure printing process, waste products caused by dirt accumulation account for more than 50% of the total waste. Dirty waste products are mainly caused by reasons such as incomplete plate wiping. Currently, operators need to manually adjust parameters such as the pressure of the wiping roller and the position of the doctor blade.

[0004] Therefore, how to reduce the frequency of manual intervention by operators in existing technologies, reduce the technical experience requirements of operators, and reduce the workload of operators has become an urgent problem to be solved. Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0006] Therefore, a first aspect of the present invention provides an adaptive intelligent wiping device.

[0007] A second aspect of the present invention provides a control method for an adaptive intelligent wiping device.

[0008] A third aspect of the present invention provides a control device for an adaptive intelligent wiping device.

[0009] A fourth aspect of the present invention provides a readable storage medium.

[0010] In view of this, a first aspect of the present invention provides an adaptive intelligent plate wiping device for a gravure printing machine. The gravure printing machine includes a printing plate cylinder. The adaptive intelligent plate wiping device includes: a wiping roller, a wiping box, a sensing system, a wiping controller, and an electrical adjustment system. The wiping roller cooperates with the printing plate cylinder for printing. The wiping box contains the wiping roller. The sensing system includes a pressure sensor. The pressure sensor, located in the wiping box, detects the pressure parameters between the wiping roller and the printing plate cylinder. The wiping controller generates a pressure adjustment command based on the pressure parameters. The electrical adjustment system, connected to the wiping controller and the wiping roller, adjusts the pressure parameters between the wiping roller and the printing plate cylinder according to the pressure adjustment command.

[0011] This invention provides an adaptive intelligent plate-cleaning device for a gravure printing machine. The gravure printing machine includes a printing plate cylinder. The adaptive intelligent plate-cleaning device includes: a plate-cleaning roller, a plate-cleaning box, a sensing system, a plate-cleaning controller, and an electrical adjustment system. The plate-cleaning roller cooperates with the printing plate cylinder for printing. The plate-cleaning box contains the plate-cleaning roller. The sensing system includes a pressure sensor, which detects the pressure parameters between the plate-cleaning roller and the printing plate cylinder. The plate-cleaning controller generates pressure adjustment commands based on the pressure parameters. The electrical adjustment system is connected to the plate-cleaning controller and the plate-cleaning roller to adjust the pressure parameters between the plate-cleaning roller and the printing plate cylinder according to the control commands. By analyzing the pressure data changes between the plate-cleaning roller and the printing plate cylinder, the appropriate clearance value range between the plate-cleaning roller and the printing plate cylinder during normal printing is calculated. Based on the feedback value of normal data, automatic clearance adjustment is performed in real time. This enables the equipment to automatically adjust the pressure parameters between the plate-cleaning roller and the printing plate cylinder, thereby improving the gravure printing quality and reducing manual operation intensity.

[0012] The adaptive intelligent wiping device provided by the present invention may also have the following additional technical features: In some possible designs, the wiping box includes: a pressure detection position, whereby, when the pressure sensor is set at the pressure detection position, the position and direction of the strain detected by the pressure sensor are consistent with the position and direction of the strain of the pressure between the wiping roller and the printing plate cylinder.

[0013] In this design, the wiping box includes a pressure detection position. When the pressure sensor is set at the pressure detection position, the location and direction of the maximum strain detected by the pressure sensor are consistent with the location and direction of the maximum strain between the wiping roller and the printing plate cylinder. Finite element simulation analysis and strain sensor placement tests were conducted based on the actual constraints and stress conditions of the wiping box. When testing the pressure detection position, during the start-up phase, the strain at the measuring point did not exceed 10 με; during stable operation, the strain fluctuated between 8.5 με and 9.5 με; in the afternoon, the strain stabilized at around 6 με; after the shift change at 6 PM, the strain at the measuring point increased significantly, then gradually returned to around 6 με. If it fell below 6 με, the pressure was adjusted upwards, and the changes in pressure measurement data corresponded one-to-one with the pressure adjustment process, with the direction of the pressure adjustment completely consistent with the actual measurement. This achieves the goal of obtaining the pressure between the wiping roller and the printing plate cylinder by detecting the pressure in the wiping box.

[0014] In some possible designs, the adaptive intelligent plate-cleaning device includes: a closed-loop control device for printing quality, which generates printing quality information; and an online monitoring system for printing plate quality, which generates printing plate quality information.

The online plate quality monitoring system includes: a camera device to acquire images of the plate after cleaning; and a quality information detection device to generate plate quality information based on the detected images. By acquiring images of the plate after cleaning with a camera device, the quality of the plate can be directly assessed. Simultaneously, the quality information detection device can detect the plate images, thus clarifying the printing quality and analyzing the plate quality information.

When a detected printing quality problem is caused by a flow rate issue with the wiping fluid, the wiping controller issues a flow rate adjustment command to adjust the flow rate of the wiping fluid flowing into the wiping roller. This resolves printing quality problems during the printing process, improves gravure printing quality, and reduces manual labor intensity.

The pressure sensor is mounted on the wiping box 2 and is used to detect the pressure parameters between the wiping roller 3 and the printing plate cylinder 1. The wiping controller 7 generates pressure adjustment commands based on the pressure parameters. The electrical adjustment system 8 receives the pressure adjustment commands and controls the pressure parameters between the wiping roller 3 and the printing plate cylinder 1 according to the control commands. By analyzing the pressure data changes between the wiping roller 3 and the printing plate cylinder 1, the appropriate clearance value range between the wiping roller 3 and the printing plate cylinder 1 is calculated during normal printing. Based on the feedback value of normal data, automatic clearance adjustment is performed in real time. This allows the equipment to automatically adjust the pressure parameters between the wiping roller 3 and the printing plate roller, thereby improving the quality of gravure printing and reducing the intensity of manual operation.
