Embodiment Construction
[0031] Below in conjunction with accompanying drawing and embodiment the present invention is further described: as figure 1 , 2 As shown in , the holographic shading laser packaging material printed product quality inspection system is used for the apparent quality inspection of the laser shading printed matter in an unfixed position, on the outside of a transfer roller 4 that supports the holographic laser shading printed sheet An LED light source 3 and a CCD scanning head 2 are provided, and the CCD scanning head 2 is installed on the laser-avoiding drive mechanism 1, and the LED light source 3 and the CCD scanning head 2 are asymmetrically arranged on both sides of the normal line of the detection point 17, The laser-avoiding drive mechanism 1 can at least move linearly and rotate around the central axis in a plane passing through the detection point 17 and perpendicular to the axis of the transfer roller 4, and is used to adjust the CCD scanning head 2 so that the CCD sca...
