[0022] The following is a clear and complete description of the technical solutions in the embodiments of the present invention, in conjunction with the accompanying drawings. The embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0023] Reference Figures 1-4 , an anti-counterfeiting printing and hot stamping mechanism, including a bottom plate 1, the upper surface of the bottom plate 1 is fixed with two side plates 2 by bolts, the interior of the two side plates 2 is provided with a slide groove 7, the slide groove 7 is slidably connected with a slider 6, a hot stamping roller 3 is rotatably connected between the two sliders 6, the top of the side plate 2 is rotatably connected with a screw rod 8, and the screw rod 8 is threadedly connected to the slider 6, the screw rod 8 rotates to make the slider 6 move upward along the slide groove 7, thereby adjusting the distance between the hot stamping roller 3 and the power roller 4, the power roller 4 is rotatably connected between the two side plates 2, and the top of the slider 6 A card slot 17 is provided, in which a connecting frame 12 is connected. The bottom of the connecting frame 12 is rotatably connected to a suction roller 15, and the hot stamping roller 3 is in contact with the suction roller 15. The lottery paper is placed between the hot stamping roller 3 and the power roller 4. The power roller 4 drives the lottery paper to move so that the hot stamping roller 3 stamps an anti-counterfeiting mark on the lottery paper. A scraper 14 is fixed to one side of the connecting frame 12 by bolts, and the scraper 14 is in contact with the suction roller 15. The suction roller 15 absorbs impurities on the hot stamping roller 3, and the scraper 14 cleans the impurities on the suction roller 15.

[0024] In the present invention, it should be noted that one side of the side plate 2 is fixed with a first elastic bracket 9 by bolts, and the first elastic bracket 9 is clamped with the rotating block 10. The first elastic bracket 9 can limit the position of the rotating block 10, thereby fixing the position of the screw rod 8 to prevent the screw rod 8 from reversing and affecting the use of the device. One side of the slider 6 is fixed with two second elastic brackets 13 by bolts, and the top of the second elastic bracket 13 is in contact with the top of the connecting frame 12. When the connecting frame 12 needs to be disassembled, the second elastic bracket 13 is separated from the connecting frame 12, and the connecting frame 12 is pulled upward. The connecting frame 12 is separated from the card slot 17 to complete the disassembly, which makes it convenient for the staff to maintain the adsorption roller 15 and dump impurities. The top of the screw rod 8 passes through the side plate 2 and is welded with a rotating block 10. The two sides of the side plate 2 are fixed with support rods 5 by bolts, and the support rods 5 are fixed to the bottom plate 1. The support rods 5 make the connection between the bottom plate 1 and the side plate 2 more secure. A collection tank 16 is provided inside the connecting frame 12, and the cleaned impurities are located in the collection tank 16, which is convenient for the staff to carry out centralized processing. A rubber cover 11 is clamped in the collection tank 16 to facilitate the staff to open and close it.

[0025] Working principle: When it is necessary to adjust the distance between the hot stamping roller 3 and the power roller 4, move the first elastic bracket 9 to separate it from the rotating block 10, rotate the rotating block 10, so that the screw rod 8 drives the slider 6 to move upward, and then the distance between the hot stamping roller 3 and the power roller 4 is adjusted, and then release the first elastic bracket 9 to make it re-engage the rotating block 10. When in use, place the lottery paper between the hot stamping roller 3 and the power roller 4, and the power roller 4 drives the lottery paper to move so that the hot stamping roller 3 stamps the anti-counterfeiting mark on the lottery paper. At the same time, the adsorption roller 15 adsorbs the impurities on the hot stamping roller 3, and the scraper 14 cleans the impurities on the adsorption roller 15, so that the cleaned impurities enter the collection tank 16.

[0026] Finally, it should be noted that those skilled in the art may modify the technical solutions described in the aforementioned embodiments or replace some of the technical features with equivalents. Any modifications, equivalent replacements, and improvements made within the spirit and principles of this utility model shall be included within the scope of protection of this utility model.
