Description

Technical Field

[0001] The utility model relates to the technical field of printing, in particular to an automatic waste screening device for printed defectives. Background Art

[0002] Printing is the technology of batch copying the contents of original manuscripts such as text, pictures, photos, anti-counterfeiting, etc. through processes such as plate making, inking, and pressurization, so that the ink is transferred to the surface of materials such as paper, textiles, plastics, leather, PVC, PC, etc. Printing is the process of transferring the approved printing plate to the printing substrate through printing machinery and special ink.

[0003] During the printing process, there are often some printing position deviations, misprints, overprints, blurred printing and other phenomena in the printed products, which need to be screened out.

[0004] However, in the existing automatic waste screening of defective printed products, sampling inspection is generally carried out by operators, and the printed products cannot be detected in real time, and the defective products cannot be screened out in time, resulting in serious mixing of defective products with finished products, affecting printing efficiency.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content
