TECHNICAL FIELD

[0001] The utility model relates to the field of printing defect detection, and specifically relates to a printing defect detection mechanism. BACKGROUND

[0002] Printing defect detection is a crucial link in the printing industry, which is of great significance to ensure the quality of printed matter, improve production efficiency and reduce cost. Cigarette packaging printing has the characteristics of full base color, many special colors, simple picture and few continuous pattern changes. In the process of printing cigarette paper, defects are inevitable. For example, misregistration, ink blurring or excessive color difference, etc. require defect detection of cigarette paper, which will use a printing defect detection mechanism.

[0003] A cigarette box printing defect detection mechanism (authorized publication number CN 205484098U) is disclosed in a Chinese patent. The patent technology can continuously obtain the printing information on the paper strip through the continuous imaging or shooting of the high-frequency camera. When a defect is found, the defect position is marked by spraying the marking spray pot in the later marking, but it can only be marked by spraying. After the entire cigarette paper roll defect detection is completed, the cigarette paper roll needs to be pulled apart to find the defect point and process the defect point position. When finding the position of the defect point, it is not easy to quickly find the position of the defect point, which is time-consuming and laborious. Therefore, the technical personnel in the art provide a printing defect detection mechanism to solve the problems raised in the above background technology. UTILITY MODEL CONTENT
