Description

Device for brushing and lubricating roller neck of printing plate roller of printing machine

Technical Field

The invention relates to a lubricating device, in particular to a roller neck brushing and lubricating device for a plate cylinder of a printing machine.

Background

The printing plate cylinder rotates at one side of the impression cylinder and is consistent with the linear speed of the impression cylinder; during short stop, the ink fountain roller and the anilox roller move upwards to be separated from the printing plate cylinder, and the ink fountain roller and the anilox roller continuously keep rotating so as to be beneficial to ink evening and keep ink on the anilox roller from drying. The ink fountain roller rotates on one side of the anilox roller, and the tangential speed of the ink fountain roller is lower than that of the anilox roller, so that the ink amount is controlled and the ink splashing is prevented. Most of the printing machines used for printing corrugated paper are combined flexographic printing machines. The units of the flexographic printing machine are independent and are arranged in a horizontal straight line. If hard particles are in the ink, the plate cylinder is easily scratched by the hard particles during ink scraping, so that the quality of a printed product is influenced by a light person, and the plate cylinder is scrapped by a heavy person. In addition, impurities on the surface of the printing material are easily mixed into the ink, accumulated too much for a long time, and easily damage the plate cylinder, so that the printing material and the ink are required to be kept clean as much as possible. In order to remove foreign matter, the ink in the ink tank may be periodically filtered or the filtering may be performed while inserting a wire mesh into the ink circulation system. Dust from the environment, whether falling into the ink or adhering to the impression cylinder, can directly damage the doctor blade and the printing surface. The roll neck part of the existing plate cylinder is inconvenient to brush, the lubricating treatment efficiency of the roll neck part is low, the roll neck part is easy to damage, and the service life of the plate cylinder is short.
