Description

Technical Field

[0001] The utility model relates to the technical field of paper powder cleaning of offset printing machines, in particular to a paper powder suction mechanism for offset printing machines. Background Technique

[0002] An offset printing machine is a type of lithographic printing machine. During printing, the printed graphics and texts are first printed from the printing plate onto the rubber cylinder, and then transferred from the rubber cylinder to the paper. According to different paper feeding methods, offset printing machines can be divided into single-sheet offset printing machines and web offset printing machines. According to the number of printing colors completed in one paper feed, they can be divided into single-color, two-color, four-color and multi-color printing machines. According to the maximum paper format that can be printed, they can be divided into small offset printing machines, six-opening, four-opening, folio and full-sheet paper printing machines. In addition, there is also a double-sided printing machine that can complete double-sided printing in one paper feed. The single-sheet offset printing machine is a lithographic printing machine used for printing high-grade commercial printed matter and packaging printed matter, and is the mainstream of modern paper printing.

[0003] However, the existing devices have the following problems:

[0004] 1. The existing devices mainly blow the paper powder directly by a blower, so that the paper powder is adsorbed due to the static electricity generated by the paper during the paper powder cleaning process, affecting the cleaning effect of the paper powder.

[0005] 2. At the same time, some devices cannot control the moisture adhered to the brush when cleaning the paper powder with water, so that the excess moisture on the connecting brush wets the paper during the cleaning process, affecting the printing effect.

[0006] Therefore, in order to solve the above problems, a paper powder suction mechanism for offset printing machines is proposed. Content of the Utility Model
