[0027] For example, in some embodiments, each set of the camera device includes a camera adjustment device 7 and a camera 8, wherein the camera adjustment device 7 is connected to the second long frame 9, and the camera 8 is connected to the camera adjustment device 7. The camera position can be adjusted up, down, left, and right through the camera adjustment device 7, so as to accurately observe the paper, take pictures of the paper, and upload the picture results to the system.

[0028] For example, in some embodiments, the light source panel adjustment device 2 includes a first square column 16, and a first right-angle plate 17 and a second right-angle plate 20 are sequentially provided on the front end surface of the first square column 16 from top to bottom, the first right-angle plate 17 and the second right-angle plate 20 are arranged opposite to each other, a first bottom plate mounting hole 18 is provided on the bottom plate of the first right-angle plate 17, and a first bottom plate connecting screw (drawn in the figure) connected to the first square column 16 is provided on the first bottom plate mounting hole 18, a first vertical plate mounting hole 19 is provided on the vertical plate of the first right-angle plate 17, and a first vertical plate connecting screw (drawn in the figure) connected to the first long frame 3 is provided on the first vertical plate mounting hole 19, a second bottom plate mounting hole 22 is provided on the bottom plate of the second right-angle plate 20, and a second bottom plate connecting screw (drawn in the figure) connected to the first square column 16 is provided on the second bottom plate mounting hole 22, and a second vertical plate connecting screw (drawn in the figure) connected to the first square column 16 is provided on the vertical plate of the second right-angle plate 20, and a second vertical plate mounting hole 21 is provided on the vertical plate of the second right-angle plate 20, and a second vertical plate connecting screw (drawn in the figure) connected to the first long frame 3 is provided on the second vertical plate mounting hole 21. This makes it easy to adjust the position of the light source panel 1 up, down, left, and right. In this solution, the bottom plate of the first right-angle plate 17 and the bottom plate of the second right-angle plate 20 are both one side in contact with the first square column 16.

[0029] For example, in some embodiments, the camera adjustment device 7 includes a second square column, a third right-angle plate and a fourth right-angle plate are sequentially arranged on the front end surface of the second square column from top to bottom, the third right-angle plate and the fourth right-angle plate are arranged oppositely, a third bottom plate mounting hole is arranged on the bottom plate of the third right-angle plate, a third bottom plate connecting screw connected to the second square column is arranged on the third bottom plate mounting hole, a third vertical plate mounting hole is arranged on the vertical plate of the third right-angle plate, a third vertical plate connecting screw connected to the second long frame is arranged on the third vertical plate mounting hole, a fourth bottom plate mounting hole is arranged on the bottom plate of the fourth right-angle plate, a fourth bottom plate connecting screw connected to the second square column is arranged on the fourth bottom plate mounting hole, and a fourth vertical plate mounting hole is arranged on the fourth vertical plate mounting hole, and a fourth vertical plate connecting screw connected to the second long frame is arranged on the fourth vertical plate mounting hole.

[0031] For example, in some embodiments, the four inner corners of the rectangular frame are all provided with connecting and fixing angle plates 4. The connecting and fixing angle plates 4 can make the overall structure of the fixed adjustment support frame more stable, providing stability for the operation of the equipment.

[0032] For example, in some embodiments, the first short frame 5 and the second short frame 2 are both provided with a rectangular frame connecting corner plate 6. The rectangular frame connecting corner plate 6 facilitates fixing the adjustable support frame at the printing outlet of the flexographic printing machine.

[0033] Working principle of the whole machine:

[0034] Pass the printed paper through the middle of the light source board and the camera, use the light source board adjustment device 2 to adjust the position of the light source board 1 away from the printed paper, and then use the camera adjustment device 7 to adjust the position of the camera 8 away from the printed paper. After adjusting the two to the appropriate positions, the light source board 1 starts to provide the light source required for the camera, and the camera 8 takes a complete picture. The printing condition of the paper can be detected through the picture, and the printing pressure of the flexographic printing machine can be automatically adjusted according to the actual situation to make the printed paper better.

[0035] In summary, the present invention adopts the above technical solution. Since the printed paper passes through the light source device and the camera device, the light source device provides the light source required by the camera device, and the camera device takes a complete picture. The printing condition of the paper can be detected through the picture, and the printing pressure of the flexographic printing machine is fed back in combination with the actual situation. Then the flexographic printing machine automatically adjusts the printing pressure to make the printed paper better. This can save costs, reduce the cost of some staff, save human resources, and avoid the need to arrange personnel for real-time supervision; it can save resources, and respond and adjust the poorly printed paper in the first time to avoid waste.

[0036] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
