[0002] At present, the demand for lottery tickets is increasing, and the winning numbers of lottery tickets are usually covered with silver paste (scratch-off strips). However, the existing lottery ticket production process is mostly to print the code on the paper through a coding mechanism, and then manually transport it to a drying device to quickly dry the printed paper. The dried paper is then transported to a silver paste covering mechanism for silver paste coating, and finally sent to the drying device for rapid drying. The entire production process is labor-intensive, and production time is wasted during the transportation process, resulting in low production efficiency.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example: Reference Figure 1-5 The online inkjet coding device shown includes an inkjet coding mechanism 1 and a silver paste coating mechanism 2. The inkjet coding mechanism 1 is used to print inkjet codes on paper, and the silver paste coating mechanism 2 is arranged on one side of the inkjet coding mechanism 1 and is used to coat silver paste on the paper after inkjet coding.

[0030] A quick-drying box 3 is provided between the inkjet printing mechanism 1 and the silver paste coating mechanism 2. A resistance heating plate 301 is provided in the quick-drying box 3. A set of support rollers 6 for supporting and guiding the paper after inkjet printing are provided at the upper and lower ends of the resistance heating plate 301. The support rollers 6 are rotatably connected to the quick-drying box 3 via a support shaft 7.

[0031] The resistance heating plate 301 divides the inside of the quick-drying box 3 into two horizontal channels, one above the other. The two sets of support rollers 6 are located in the two horizontal channels respectively.

[0032] A steering guide roller 201 is rotatably connected to the silver paste covering mechanism 2. A coating strip 202 for coating silver paste is installed on the top wall of the silver paste covering mechanism 2. The steering guide roller 201 is located on the side of the coating strip 202 away from the quick-drying box 3.

[0033] A winding roller for winding up the finished printed product is also installed on the side of the quick-drying box 3 away from the silver paste covering mechanism 2. A driving motor 4 for driving the steering guide roller 201 to rotate and a transmission belt group 5 connected between the steering guide roller 201 and the winding roller are installed on the silver paste covering mechanism 2.

[0034] Among them, the paper enters the inkjet coding mechanism 1 from the inlet end of the inkjet coding mechanism 1 and is printed in the inkjet coding mechanism 1. Then, it passes through the outlet end of the inkjet coding mechanism 1 into one of the channels of the quick-drying box 3 and is supported by one group of support rollers 6. Then, it is changed in direction by the steering guide roller 201 and coated with silver paste by the coating strip 202. Then, it passes through another channel in the quick-drying box 3 and is wound onto the winding roller.

[0035] Based on the above structure, during use, the staff first guides the end of the printed continuous paper to pass through the coding mechanism 1, one of the channels of the quick-drying box 3, the silver paste covering mechanism 2, and the other channel of the quick-drying box 3, and finally wind it up on the winding roller, and start the drive motor 4, so that the drive motor 4 drives the steering guide roller 201 and the transmission belt group 5 to rotate simultaneously, so that the paper completes the coding printing in the coding mechanism 1, and then passes through the quick-drying box 3 for rapid drying, and enters the silver paste covering mechanism 2 to be coated with silver paste (that is, the scratching strip covering the surface of the open lottery ticket), and then enters the quick-drying box 3 again for rapid drying, and finally winds the finished product through the winding roller, realizing the fully automated production effect of coding printing-drying-coating-drying-collection, thereby accelerating production efficiency. At the same time, the heat energy of the quick-drying box 3 is fully utilized, and the product can be dried repeatedly without the need for a separate drying equipment, reducing the equipment cost of the entire device.

[0036] Furthermore, the front and rear side walls of the quick-drying box 3 are provided with adjustment holes 302;

[0037] The support roller 6 is rotatably sleeved on the support shaft 7 , and both ends of the support shaft 7 movably pass through the two adjustment narrow holes 302 and are frictionally fixed to the quick-drying box 3 through adjustable fixing parts.

[0038] The end of the support shaft 7 that movably passes through the adjustment narrow hole 302 is provided with a threaded end 701;

[0039] The adjustable fixing member includes a fastening nut 8 , which is threadedly sleeved on the threaded end 701 , and one side of the fastening nut 8 is tightly pressed against the outer wall of the quick-drying box 3 .

[0040] By adjusting the settings of the narrow hole 302, the threaded end 701 and the fastening nut 8, during daily use, the fastening nut 8 is in a tightened state, that is, one side of the fastening nut 8 is pressed against the outer wall of the quick-drying box 3. The staff can loosen the fastening nut 8 so that the support shaft 7 can slide in the adjusting narrow hole 302, thereby adjusting the horizontal height of the support shaft 7, thereby adjusting the distance between the paper after inkjet printing or paper coated with silver paste on the support shaft 7 and the resistance heating plate 301, so as to achieve the effect of adjusting the drying speed, that is, the farther the paper is from the resistance heating plate 301, the slower the drying speed, and vice versa, thereby achieving the purpose of being able to flexibly adjust the drying efficiency when using the online inkjet printer device, which can be adapted to different production needs and is more flexible and convenient to use.

[0041] Furthermore, a side wall of the fastening nut 8 close to the quick-drying box 3 is provided with a friction-increasing rib 801, and a plurality of friction-increasing ribs 801 are provided and distributed along the circumference of the side wall of the fastening nut 8;

[0042] A friction-increasing ring piece 9 is fixed to the outer wall of the quick-drying box 3. The friction-increasing ring piece 9 is a flexible gasket (such as made of rubber material) and covers the outer side of the adjustment narrow hole 302. One side of the fastening nut 8 is interference fit with the friction-increasing ring piece 9.

[0043] By setting the friction-increasing ribs 801 and the friction-increasing ring sheets 9, the friction between the fastening nut 8 and the outer wall of the quick-drying box 3 can be greatly enhanced when tightening, thereby enhancing the stability of the positioning with the support shaft 7, and preventing the support shaft 7 from sliding up and down during use, resulting in the distance between the paper and the resistance heating plate 301 being inconsistent with the preset distance, thereby ensuring the stability of the quality of the finished product after drying.

[0044] Furthermore, the support shaft 7 is integrally formed with an inner pull-out baffle 702 in the middle between the inner side of the quick-drying box 3 and the end of the support roller 6. The side wall of the inner pull-out baffle 702 away from the support roller 6 abuts against the inner wall of the quick-drying box 3. Through the setting of the inner pull-out baffle 702, the two ends of the support shaft 7 can be limited to avoid horizontal displacement of the support shaft 7 when the fastening nut 8 is tightened, and at the same time, it ensures that the support shaft 7 can be better clamped between the two side walls of the quick-drying box 3 to ensure stability when moving up and down.

[0045] The working principle of the present invention is as follows: during daily use, first, the staff guides the end of the printed continuous paper to pass through the coding mechanism 1, one of the channels of the quick-drying box 3, the silver paste covering mechanism 2, and the other channel of the quick-drying box 3 in sequence, and finally winds it up on the winding roller, and starts the drive motor 4, so that the drive motor 4 drives the steering guide roller 201 and the winding roller to rotate simultaneously through the transmission belt group 5, so that the paper completes the coding printing in the coding mechanism 1, and then passes through the quick-drying box 3 for rapid drying, and enters the silver paste covering mechanism 2 for coating silver paste, and then enters the quick-drying box 3 for rapid drying again, and finally winds the finished product through the winding roller, realizing the fully automated production effect of coding printing-drying-coating-drying-collection, thereby accelerating production efficiency, and at the same time, making full use of the thermal energy of the quick-drying box 3, and being able to repeatedly dry the product without the need for a separate drying device, thereby reducing the equipment cost of the entire device;

[0046] In addition, the staff can also adjust the horizontal height of the support shaft 7 by loosening the fastening nut 8 so that the support shaft 7 can slide in the adjusting narrow hole 302, thereby adjusting the distance between the paper after inkjet printing or paper coated with silver paste on the support shaft 7 and the resistance heating plate 301, so as to achieve the effect of adjusting the drying speed, that is, the farther the paper is from the resistance heating plate 301, the slower the drying speed, and vice versa. In this way, the purpose of being able to flexibly adjust the drying efficiency when using the online inkjet coding device is achieved, which can be adapted to different production needs and is more flexible and convenient to use.

[0047] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
