Ultrasonic cleaning device of color separation plate of offset printing press

Abstract

The invention discloses a ultrasonic cleaning device of a color separation plate of an offset printing press. Two sets of ultrasonic vibrators are arranged at the lower part of a rectangular cleaning tank along one diagonal line; the ultrasonic vibrators are connected with ultrasonic generators; two sets of brushes tangential pairwise are arranged in the area of the other diagonal line in the cleaning tank; two shafts of each set of tangential brushes are engaged with each other; and through design a special cleaning turntable of the color separation plate, a mode of combining mechanical cleaning with ultrasonic cleaning is adopted to control the cleaning time of the color separation plate within 5 min. The device is simple in operation and easy to master. Through actual trial operation in the production scene and optimization of each design in the trial operation process, the problem of influence on the ultrasonic effect by the placing position of the color separation plate in each-batch cleaning of multiple color separation plates by singly using ultrasonic waves is solved; through mechanical brush and chemical reagent cleaning, the cleaning efficiency and the cleaning effect are achieved, and meanwhile, cleaning liquid enriched with ink after cleaning is guaranteed to not pollute the device; and the cleaning liquid can be recycled to achieve economy and environmental protection.

Description

【Technical field】 [0001] The invention relates to the field of cleaning of printing equipment, in particular to an ultrasonic cleaning device for a color separation plate of an offset printing machine. 【Background technique】 [0002] At present, the color separation plates of special printing equipment need to be cleaned in time. Due to the large number of color separation plates and the high viscosity of the printing ink, the mechanical cleaning equipment that has been developed cannot meet the needs. At present, it mainly relies on manual cleaning. A large number of color separation boards are used in the production of trademark printing operations. The color separation board is to divide an ink fountain roller into regions, so that the same ink fountain roller can be filled with sheet blocks of various colors. Due to changes in product design requirements, after changing different colors or color separation positions, the color separation board needs to be cleaned many t...

Problems solved by technology

However, after investigation, due to the tight adhesion of the ink in the actual process of the equipment, the above washing machine takes a long time to combine mechanical cleaning with chemical cleaning, and the cleaning effect is not good, so it has not been effectively used in production practice.
