Technical Field

[0001] The utility model relates to the technical field of static electricity removal for offset printing machines, in particular to a static electricity removal mechanism for offset printing machines. Background Art

[0002] An offset printing press is a type of lithographic printing press. During printing, the printed image is first printed from the printing plate onto a rubber cylinder, and then transferred to paper by the rubber cylinder. The offset printing press needs to be subjected to static electricity removal during operation, so an offset printing press static electricity removal mechanism is required. The "offset printing press static electricity removal mechanism" disclosed in the publication number "CN218020666U" has solved the technical drawback that the existing offset printing presses do not have a static electricity removal function. However, static electricity removal mechanisms of similar structures still have many defects in actual use. For example, the static electricity removal structure is single, and most of them can only remove static electricity from printed paper. In the actual operation of the offset printing press, static electricity may also occur on the printing roller. When the printing roller of the offset printing press contains static electricity, its printing quality will be affected. For this reason, we have designed an offset printing press static electricity removal mechanism to solve the above problems. Utility Model Content
