Description

Technical Field

[0001] The utility model relates to the technical field of automatic removal of printing defects of paper products, in particular to a device for automatically removing printing defects of paper products. Background Art

[0002] During the printing process of paper products, due to operating errors of the printing device and paper quality problems, pattern displacement and missed printing often occur. Therefore, printing inspection of paper products is an indispensable part of the production process. In the fast-paced modern life, the pressure on the printing industry is increasing day by day. Faced with mountains of paper products, traditional manual inspection is not only time-consuming and labor-intensive, but also prone to missed inspections and misjudgments, making quality control a major problem. Therefore, devices that can detect the printing quality of paper products have emerged. For example, the Chinese utility model patent with patent number CN219830879U is an online detection device for label printing. By setting a guide plate, a fixed plate, a baffle, a turntable and a handle, it prevents the paper product from shifting, facilitates the contact image sensor to detect the label, avoids manual inspection, and improves efficiency.

[0003] There are still some problems in the use of the above device. After finding defective printed products, the device cannot further process the defective products. The defective products at the marked areas still need to be manually picked out, which increases the operating steps of the staff and does not reduce the labor intensity of the staff. There is still a risk that defective products will be missed and not picked out during the picking process, affecting the qualified rate of paper product printing. Utility Model Content

[0009] Beneficial effects of the utility model:

[0010] The present invention provides an automatic rejection device for printing defects on paper products. A chute is provided on a support frame, and a sliding baffle is installed in the chute. The sliding baffle cooperates with the limit baffle to fix the position of the paper product to be inspected. The height position of the printing inspection mechanism is adjusted by adjusting the upper and lower positions of the telescopic bracket to adapt to the thickness of the paper product to be inspected. At the same time, the telescopic bracket adjusts its position along the track, and the printing inspection mechanism can then inspect the paper product to be inspected along the Y-axis. The printing inspection mechanism then slides along the horizontal track to inspect the paper product along the X-axis. The device is also provided with a liftable top plate. When the quality of the paper product to be inspected is qualified, the top plate does not descend, and the push plate on the rear side of the support frame pushes the qualified product to the unloading plate for collection. When the quality of the paper product to be inspected is unqualified, the top plate descends, the front telescopic rod contracts a second time, and the top plate tilts forward to slide the defective product onto the supporting platform for recycling.
