Technical Field
[0001] The utility model relates to the technical field of printing, and particularly relates to a printing cylinder cleaning device. Background Art
[0002] Modern printing machines generally consist of mechanisms such as plate loading, ink coating, impression, and paper feeding (including folding). Its working principle is as follows: First, the text and images to be printed are made into printing plates and installed on the printing machine. Then, ink is applied to the areas with text and images on the printing plate manually or by the printing machine, and then directly or indirectly transferred to paper or other printing substrates (such as textiles, metal plates, plastics, leather, wood boards, glass, and ceramics), thereby replicating the same printed matter as the printing plate.
[0003] The cylinders of printing machines play an important role. Their geometric accuracy directly affects the quality of printed matter. However, due to long-term use, the water (including dampening solution, alcohol, etc.) on the plate cylinder is transferred to the impression cylinder, and the ink is sprayed in inappropriate places (such as the double-size cylinder that has been used for the quarto part for a long time), corrosion and collapse will occur. As a result, the color registration of the collapsed part is inaccurate, making the expensive printing machine greatly inferior. Content of the Utility Model

A dirt collecting groove handle 17 is fixedly connected to the dirt collecting groove 16 in the direction close to the side opening of the groove 15.
[0021] Working principle:
[0022] When the roller passes over the first movable plate, the roller lifts up the first movable plate, enabling the drum to continue moving forward. When the roller moves to the cleaning track, the drum comes into contact with the scraper and the brush successively. The positions where the scraper and the brush are set are exactly the maximum height that the drum can reach when passing by. The scraper scrapes off the garbage on the drum, and the brush brushes off the remaining garbage on the drum. The garbage cleaned from the drum by the scraper and the brush falls into the dirt collecting tank. When the garbage in the dirt collecting tank reaches a certain height, the dirt collecting tank can be pulled out from the groove through the dirt collecting tank handle, facilitating collection and cleaning. When the drum retracts, the roller will move upward along the first movable plate, move onto the guide rail frame and move back from the guide rail frame, preventing the drum from returning along the original path and affecting the original printing effect.
