Each printing color group has an impression cylinder, a printing plate cylinder and an ink feeding device, and the structures of all printing color groups are the same. The stack type flexographic printing press can print from 1 to 8 colors, but mostly 6 colors. If it is equipped with a turning device, it can also perform front and back printing.

An electric telescopic rod 14 is installed on the side of the bottom plate 1. A rectangular plate 15 is fixedly connected to the side end of the electric telescopic rod 14. A iron rod 18 is rotatably connected inside the rectangular plate 15. A disc 16 is fixedly connected to the side end of the iron rod 18. A limiting ring 17 is arranged outside the iron rod 18. The limiting ring 17 is slidably connected to the iron rod 18. A magnet 19 is fixedly connected to the inner wall of the limiting ring 17. The magnet 19 is magnetically connected to the iron rod 18. A paper body 9 is wound around the outside of the iron rod 18. A laser receiving plate 10 is fixedly connected to the top of the bottom plate 1. A top groove 11 is opened inside the bottom plate 1. A sliding plate 12 is slidably connected inside the top groove 11. A laser emitting plate 13 is fixedly connected to the top of the sliding plate 12.

[0026] In this embodiment, as Figure 2 and Figure 3 shown, the laser emitting plate 13 and the laser receiving plate 10 are opposite in position. A bolt 20 is threadedly connected to the bottom of the bottom plate 1. The top of the bolt 20 extends into the sliding plate 12. A control board 3 is fixedly connected to the side of the bottom plate 1. Both the laser receiving plate 10 and the laser emitting plate 13 are electrically connected to the control board 3. The control board 3 is electrically connected to the electric telescopic rod 14. A first dust removal pad 4 and a vertical plate 6 are respectively fixedly connected to the surface of the bottom plate 1. A through hole 7 is opened inside the vertical plate 6. A moving plate 8 is slidably connected inside the vertical plate 6.

[0027] Among them, according to the actual size of the paper body 9, the limiting ring 17 can be moved correspondingly outside the iron rod 18, and then the sliding plate 12 and the laser emitting plate 13 can be moved in the top groove 11 according to the size of the paper body 9. Furthermore, the laser emitted by the laser emitting plate 13 can be received by the laser receiving plate 10. When the laser is blocked by the paper body 9, the laser receiving plate 10 cannot receive the laser signal, then the electric telescopic rod 14 starts to work through the control board 3, and further the position of the iron rod 18 is adjusted, so that the paper body 9 can be corrected and the paper body 9 can be wound smoothly around the outside of the iron rod 18.

[0028] In this embodiment, as Figure 1 and Figure 4As shown, a second dust removal pad 5 is fixedly connected to the side surface of the moving plate 8. The second dust removal pad 5 and the first dust removal pad 4 are opposite in position. The second dust removal pad 5 and the first dust removal pad 4 are respectively arranged on both sides of the paper body 9. A plug rod 21 is inserted into the side surface of the vertical plate 6.

Then, by rotating the disc 16, the paper body 9 can be wound around the outside of the iron rod 18, and after the laser emission plate 13 emits laser light, the laser is received by the laser receiving plate 10. When the laser receiving plate 10 cannot receive the laser light, the switch of the electric telescopic rod 14 is turned on through the control board 3, and the rectangular plate 15 and the iron rod 18 are driven to move by the electric telescopic rod 14, so that the paper body 9 can be smoothly wound on the surface of the iron rod 18. At the same time, when the paper body 9 is wound, the dust on the surface of the paper body 9 can be removed by the first dust removal pad 4 and the second dust removal pad 5, improving the cleanliness of the surface of the paper body 9 during winding.
