Description

Technical Field

[0001] The invention relates to the technical field of corrugated board printing, in particular to a cleaning device for a corrugated board printing roller and a cleaning method thereof. Background Art

[0002] Printing roller is a key component in printing press, used to transfer ink to printing plate or directly printed material. According to different printing processes, printing roller can be divided into many types, such as lead roller, rubber roller and metal roller.

[0003] Cleaning the printing roller is crucial to ensure printing quality and extend the life of the equipment. Use appropriate detergent and soft cloth to gently wipe the roller surface at the end of each job or when changing ink to avoid scratches. At the same time, regularly check the wear and tear and replace damaged rollers in time to prevent cross contamination. Proper cleaning and maintenance can effectively improve printing results. For example, a roller cleaning device for ink printing disclosed in Chinese patent publication number (CN218702137U) records: "It includes a body, a drain pipe is integrally formed on the surface of the body, a top cover is hinged on the top of the body, a nozzle is installed on the bottom of the top cover, and a support leg is welded to the bottom of the body. The utility model can drive the brush to move synchronously to brush the roller by converting the rotation of the first threaded rod into the linear movement of the traction seat through the setting of the mobile brushing assembly, and the distance between the brush and the roller can be adjusted through the setting of the connecting assembly to adapt to rollers of different sizes, thereby improving the overall practicality. At the same time, the setting of the limit stop bar, the claw, the clamping edge, the connecting arm, the slide groove, the tenon and the groove can realize the overall disassembly of the connecting seat, the adjustment seat and the mounting seat, thereby facilitating the cleaning of the brush and preventing impurities on the surface of the brush from affecting the subsequent cleaning effect on the roller."

[0004] In summary, the device still has the following technical problems: when the device cleans the printing roller, it cleans the printing roller through the self-rotation of the printing roller in conjunction with the cleaning brush, but the cleaning brush used in the device only contacts one side of the printing roller. If the cleaning brush moves faster, the contact time with the surface of the printing roller will be too short and the printing roller cannot be fully cleaned. If the moving speed of the cleaning brush is slower, the overall cleaning efficiency of the printing roller will be too low. Therefore, it is necessary to propose a cleaning device and a cleaning method for a corrugated cardboard printing roller, so as to provide a new technical solution to solve the technical problems mentioned in the above patents.
