Description

Technical Field

[0001] The invention relates to the technical field of auxiliary equipment for offset printing industry, in particular to a device for cleaning a color separation baffle of an offset printing machine. Background Art

[0002] Rainbow printing technology is a printing technology commonly used by offset printing machines in the industry. This anti-counterfeiting technology requires the use of color baffles to partition the ink. In order to ensure the quality of printed products, each color group of the printing machine needs to be cleaned and maintained every week. Among them, the cleaning of the color baffles is an important task for each equipment cleaning and maintenance. Due to differences in printing processes, the number of color baffles used for each device ranges from 20 to 70. At present, these color baffles are cleaned manually, which requires steps such as scraping ink, soaking, brushing, and wiping. It takes 1 to 1.5 hours to clean the color baffle of a device, which is labor-intensive, and long-term contact with ink and cleaning agents is not good for human health.

[0003] Since the rainbow printing technology is relatively rarely used in society, there is no special cleaning equipment for color barrier plates. The rainbow printing technology is relatively widely used in special industries, and most companies still use traditional manual cleaning methods to clean color barrier plates. Problems such as high labor intensity, long occupancy time, and incomplete cleaning are common problems faced by all companies. There have been related designs in the industry, which use an immersion cleaning method. The immersion time is relatively long, and each printing machine needs to be equipped with a cleaning device. The liquid consumption is large, which is not suitable for the increasingly stringent environmental management requirements. The cleaning time is long, and it is difficult to adapt to the requirements of flexible production and rapid maintenance. Therefore, it is necessary to design a fast, efficient, and environmentally friendly color barrier plate cleaning equipment that can meet the actual production organization model.
