[0035] Below, in conjunction with the accompanying drawings, a printer for spraying anti-counterfeiting QR codes provided in an embodiment of the present application is described in detail through specific embodiments and application scenarios.

[0036] Example 1:

[0037] like Figures 1 to 4As shown, an embodiment of the present application provides a spray printer for spraying anti-counterfeiting QR codes, comprising a conveying device 1, a mounting frame 2, a spray terminal 3, and a No. 1 slide rail 4, characterized in that a mounting block 5 is slidably mounted on the No. 1 slide rail 4, the mounting block 5 is provided with an arc groove 51, and a circular arc slide rail 52 is provided on the arc groove 51, the spray terminal 3 is fixedly connected with an arc block 31 matching the arc groove 51, and the arc block 31 is fixedly connected with an arc slider 32; wherein, the arc slider 32 is slidably mounted in the arc slide rail 52, and the inclination angle of the spray terminal 3 is adjusted by the adjustment structure 6.

[0038] Furthermore, the adjustment structure 6 includes an adjustment block 61 and an adjustment groove 62. The adjustment groove 62 is arranged in the mounting block 5 and is connected to the arc slide rail 52. The adjustment block 61 is fixedly connected to the arc slider 32; wherein, the adjustment block 61 can be pushed to slide in the adjustment groove 62 by a pushing member 63.

[0039] Furthermore, the adjustment block 61 includes a pair of linkage blocks 611 and a connecting block 612. One end of the connecting block 612 is fixedly connected to the arc slider 32, and the other end is fixedly connected to a pair of linkage blocks 611. A sliding groove 613 is provided on the pair of linkage blocks 611.

[0040] Furthermore, the pushing member 63 includes a motor 631, a threaded rod 632 and a sliding block 633. The threaded rod 632 is rotatably installed in the adjusting groove 62, the motor 631 is fixedly installed at the bottom end of the mounting block 5, the motor 631 is fixedly connected to the threaded rod 632, the sliding block 633 is slidably installed in the adjusting groove 62, and is movably connected to the threaded rod 632 through a threaded hole 634 provided thereon; wherein, a pair of connecting cylinders 635 are provided on the threaded rod 634, and the pair of connecting cylinders 635 are respectively slidably installed in a pair of the sliding grooves 613.

[0041] Furthermore, an indicator scale 33 is provided on the arc block 31 , and an indicator arrow 53 is provided on the mounting block 5 . The indicator scale 33 and the indicator arrow 53 are used to feedback the inclination angle of the spray terminal 3 .

[0042] In this embodiment of the present application, due to the adoption of the above-mentioned structure, a mounting frame 2 is fixedly mounted on the conveying device 1, a No. 1 slide rail 4 is fixedly mounted on the mounting frame 2, a mounting block 5 is slidably mounted on the No. 1 slide rail 4, and a spray terminal 3 is movably mounted on the mounting block 5. When it is necessary to inkjet an object with an inclined surface, the tilt angle can be input to the external control, the motor 631 is started, and the threaded rod 632 is driven to rotate. The rotation of the threaded rod 632 drives the sliding block 633 to slide in the adjusting groove 62. The sliding block 633 slides through a pair of connecting cylinders 635 and a pair of sliding grooves 613 to drive the adjusting block 61 to slide. At the same time, under the restriction of the arc slider 32 and the arc slide rail 52, the adjusting block 61 slides and drives the arc block 31 to slide along the trajectory of the arc slide rail 52, thereby adjusting the angle of the spray terminal 3 so that the spray terminal 3 is perpendicular to the inclined surface;

[0044] Example 2:

[0045] like Figures 5 to 7 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, a No. 2 slide rail 21 is provided on the mounting frame 2, and a sliding base 71 is slidably installed on the No. 2 slide rail 21. A rotating cavity 73 is provided on the sliding base 71, and a dust block 72 is movably installed in the rotating cavity 73. The dust block 72 can be parallel to the bottom end of the spray terminal 3 through the rotating structure 8; wherein, the sliding base 71 can move the dust block 72 to the bottom of the spray terminal 3 through the pushing device 9.

[0046] Furthermore, the rotating structure 8 includes a pair of adjusting motors 81 and a pair of rotating rods 82. A pushing groove 83 is provided on the sliding base 71, and a pair of rotating rods 82 are rotatably installed in the pushing groove 83.

By adjusting the position of the pair of pushing blocks 84, the inclination angle of the dust-proof block 72 can be adjusted.

[0047] Furthermore, the dustproof block 72 includes a pressure plate 721, a blocking block 722 and a rotating ball 723. One end of the pressure plate 721 is fixedly connected to the blocking block 722, and the other end is fixedly connected to the rotating ball 723. The rotating ball 723 is rotatably installed in the rotating cavity 73.

[0048] Furthermore, the pushing device 9 includes a hydraulic cylinder 91 and a hydraulic rod 92 . The hydraulic cylinder 91 is fixedly mounted on the mounting frame 2 . The front end of the hydraulic cylinder 91 is connected to the hydraulic rod 92 . The hydraulic rod 92 is fixedly connected to the sliding base 71 .

[0049] In this embodiment of the present application, due to the adoption of the above-mentioned structure, after the printing is completed, the hydraulic cylinder 91 is started, and the hydraulic rod 92 pushed by the hydraulic cylinder 91 moves, and the hydraulic rod 92 drives the sliding base 71 to slide until the blocking block 722 moves to the bottom of the printing terminal 3, and then according to the previously input angle, the pair of adjusting motors 81 are controlled to start, and the pair of adjusting motors 81 are started to respectively drive the corresponding rotating rods 82 to rotate, and the rotating rods 82 rotate to drive the corresponding pushing blocks 84 to slide up and down in the pushing grooves 83, and the pair of pushing blocks 84 are respectively pressed against the blocking blocks 722. The two ends of the pressure plate 721 extend to the height of the pushing groove 83 through a pair of pushing blocks 84, which can push one end of the pressure plate 721 to rise. Since the rotating ball 723 is rotatably installed in the rotating cavity 73, the inclination angle of the pressure plate 721 can be adjusted so that the blocking block 722 is parallel to the bottom end of the spray terminal 3. At this time, the blocking block 722 just fits with the bottom end of the spray terminal 3, thereby blocking the nozzle of the spray terminal 3, preventing a large amount of dust from entering the nozzle of the spray terminal 3, extending the overall service life of the spray terminal 3, and reducing the frequency of equipment replacement.
