[0002] Gravure printing is a kind of printing process, with ink layer thick, color bright, high saturation, high printing quality and stability, printing speed, can truly restore original manuscript effect and other advantages. In foreign countries, gravure is used for magazines and other fine publications, also applied to the field such as banknote, packaging printing, decorative materials. In China, gravure is mainly applied to soft packaging, paper packaging, wood grain decoration, leather materials etc. With the research and development and wide application of water-based gravure ink, gravure printing has become an important printing technology that meets the environmental protection requirements, and is applied to more and more printing fields. After plate roller completes processes such as electrography and chrome plating, the plate roller needs to be polished, and polishing is to polish burrs on the edge of the mesh hole in the chrome plating process.

[0003] Patent CN210335513U discloses a kind of polishing device of printing plate roller, including support base, the support base is equipped with polishing block, the support base is equipped with rotating motor, and rotating motor one end is rotatably connected with printing plate roller, the printing plate roller is distributed with polishing block same straight line, support base one side is equipped with servo motor, and servo motor one end is equipped with screw rod, and screw rod is inserted with sliding block, the sliding block one end is connected with rotating motor, and rotating motor is slidably connected with support base on screw rod by sliding block. The inner wall of the polishing block is provided with a connecting buckle groove, and the polishing block is provided with a polishing grinding wheel, the outer wall of the polishing grinding wheel is provided with a connecting buckle block, and the polishing grinding wheel is slidably and fixedly connected with the polishing block in the connecting buckle groove by the connecting buckle block. However, the above-mentioned patent has some deficiencies, the polishing device of this patent is to place the printing plate roller in the polishing grinding wheel, and the contact point of the printing plate roller with the polishing grinding wheel during rotation will cause uneven pressure distribution due to factors such as placement position and rotation accuracy, resulting in inconsistent polishing effect on the surface of the printing plate roller, over-polishing in some places and under-polishing in some places, affecting the flatness and smoothness of the printing plate roller, and further affecting the printing quality. Secondly, the debris generated during polishing will be left in the polishing grinding wheel, and the area contacted by the printing plate roller and the polishing grinding wheel is relatively closed, making it difficult to discharge the debris. If these debris cannot be cleaned in time, it may be re-rolled into the polishing process. Finally, since the position of the printing plate roller in the grinding wheel is relatively fixed, the part of the polishing grinding wheel contacted with the printing plate roller will be subjected to continuous friction and pressure during long-term polishing, which can easily cause local severe wear of the grinding wheel, resulting in uneven wear of the grinding wheel and further affecting the polishing effect.
