[0026] Some embodiments of the present application will be described in detail below with reference to the drawings. The features in the following embodiments can be combined with each other without conflict.

[0027] Example 1:

[0028] like Figure 1 and Figure 3 As shown, a continuous printing color detection device includes: a conveying device 10, a leveling device 20 disposed below the conveying device 10, and a detection device 30 mounted on the leveling device 20; the detection device 30 is perpendicular to the leveling device 20.

[0029] The conveying device 10 is used to transport paper. When the paper is transported to the flattening device 20, the detection device 30 on the flattening device 20 detects the printing color of the paper.

[0030] like Figure 1 and Figure 3 As shown, the conveying device 10 includes a drive motor 11, a drive roller 12 mounted on the drive motor 11, a driven roller 13 paired with the drive roller 12, and printing paper 14 disposed between the driven roller 13 and the drive roller 12; the leveling device 20 is disposed between the driven roller 13 and the drive roller 12, and below the printing paper 14.

[0031] When the drive motor 11 starts, it drives the active roller 12 to rotate. The active roller 12 and the driven roller 13 are connected into a whole by the printing paper 14. At this time, the printing paper 14 is wound from the driven roller 13 onto the active roller 12. During this process, the printing paper 14 passes through the flattening device 20. The flattening device 20 can flatten the printing paper 14 on the flattening device 20. Since the flattening device 20 and the detection device 30 are perpendicular to each other, the flattened printing paper 14 and the detection device 30 are perpendicular to each other. This setting effectively improves the detection accuracy of the detection device 30.

[0032] like Figures 3 to 5 As shown, the leveling device 20 includes two supports 21, tension rollers 22 respectively mounted on the two supports 21, and a leveler 23 disposed between the two tension rollers 22; the leveler 23 is mounted between the two supports 21; the printing paper 14 is leveled on the leveler 23 by the tension rollers 22.

[0033] The printing paper 14 first passes under the left tension roller 22, then passes through the straightener 23, and then passes under the right tension roller 22 to reach the drive roller 12; during the transfer of the printing paper 14, the tension roller 22 ensures that the printing paper 14 can easily enter the straightener 23 in a straight state.

[0034] Furthermore, the straightener 23 includes a platform 231, two limiters 232 installed at both ends of the platform 231, and a positioning groove 233 disposed between the two limiters 232; the limiters 232 are provided with paper passage holes 234.

[0035] To further ensure that the printing paper 14 remains flat after passing through the tension roller 22 and then through the straightener 23, two limiters 232 are provided at both ends of the platform 231 of the straightener 23. The printing paper 14 enters through the paper passage hole 234 on the left limiter 232 and exits through the paper passage hole 234 on the right limiter 232. The paper passage hole 234 can be set to be the same size as the printing paper 14. In this way, the printing paper 14 can always appear flat on the platform 231 after passing through the two limiters 232, which also ensures that the detection device 30 is always perpendicular to the printing paper 14, thus improving the detection accuracy.

[0036] like Figure 1 , Figure 2 and Figure 6 As shown, the detection device 30 includes a moving device 31, a detector 32 mounted on the moving device 31, and a marker 33 disposed below the detector 32; the marker 33 is mounted on the moving device 31.

[0037] When the printing paper 14 is laid flat on the platform 231, the detector 32 can detect it from left to right or from right to left via the moving device 31. During the detection process, if the color difference on the page of printing paper 14 is found to be too large, the moving device 31 will stop moving, the marker 33 will be activated, and a mark will be made on the page of printing paper 14. Then the moving device 31 will continue to move, and the detector 32 will continue to detect. After the printing paper 14 on the platform 231 has been completely detected, the drive motor 11 will be started to wind the detected printing paper 14 onto the drive roller 12, and the next page will be replaced for detection. After the entire bundle of printing paper 14 has been detected, the unqualified printed pages will be cut off, ensuring the continuity of the detection process of the entire bundle of printing paper 14.

[0038] The marker 33 can be a combination of a cylinder and a stamp. When an unqualified page is detected, the cylinder is activated and the stamp is pushed onto the printing paper 14 to mark it. Of course, the above is one embodiment and this embodiment is not limited.

[0039] Furthermore, the moving device 31 includes two moving tracks 311, a drive beam 312 mounted on the two moving tracks 311, a pressure plate 313 mounted under the drive beam 312, and two sliders 314 disposed at both ends of the pressure plate 313.

[0040] The pressure plate 313 is connected to the platform 231 via a slider 314 inserted into the positioning slot 233. This arrangement, together with the moving track 311, ensures that the drive beam 312 and the pressure plate 313 always move on the platform 231. When the slider 314 is inserted into the positioning slot 233, the gap between the pressure plate 313 and the platform 231 (e.g., ...) Figure 2 This ensures that the printing paper 14 adheres better to the platform 231, further improving the detection accuracy.

[0041] Furthermore, the moving track 311 includes a track plate 3111, two mounting plates 3112 installed at both ends of the track plate 3111, a rack 3113 installed between the two mounting plates 3112, and two limiting shafts 3114 disposed on both sides of the rack 3113.

[0042] Furthermore, the drive beam 312 includes a beam plate 3121, two connectors 3122 installed at both ends of the beam plate 3121, a drive shaft 3123 disposed between the two connectors 3122, and two gears 3124 mounted on the drive shaft 3123; a moving motor 3125 is installed at one end of the drive shaft 3123; two limiting holes 3126 are provided on the connectors 3122; and the gears 3124 are disposed between the two limiting holes 3126 of the connectors 3122.

[0043] like Figure 3 As shown, the four limiting shafts 3114 on the two moving tracks 311 are respectively inserted into the limiting holes 3126 of the corresponding connectors 312, so that the crossbeam plate 3121 is mounted between the two moving tracks 311. At this time, the two connectors 312 on the crossbeam plate 3121 can slide on the four limiting shafts 3114.

[0044] The drive shaft 3123 between the two connecting parts 3122 has a gear 3124 mounted on it. The gear 3124 meshes with the rack 3113 on the moving track 311. The drive shaft 3123 is driven to rotate by the moving motor 3125 mounted on it, which causes the gear 3124 on the drive shaft 3123 to move on the rack 3113.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
