[0002] A QR code uses black and white geometric patterns arranged in a regular pattern on a flat surface to record data symbols. A QR code printer is a device specifically designed to print QR codes on various surfaces. Anti-counterfeiting QR codes can protect consumers and build a positive reputation for businesses.

[0003] In the process of implementing this application, the inventor discovered that the existing technology has the following problems: the traditional QR code printing device includes a bracket, a nozzle, a guide rail, and other structures, but lacks a structure that can move the nozzle, cannot flexibly adjust the position, and cannot print the anti-counterfeiting QR code accurately enough. At the same time, the printed QR code cannot be dried in time, which easily causes ink loss.

[0004] Therefore, those skilled in the art provide an anti-counterfeiting two-dimensional code printing device to solve the problems raised in the above background technology. Utility Model Content

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.

[0025] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4, The utility model provides an embodiment: an anti-counterfeiting two-dimensional code printing device, including a No. 1 support plate 1 and a table leg 3, a No. 2 fixing block 25 is fixedly connected to both sides of the top surface of the No. 1 support plate 1 near the center line, and the inner walls of the two No. 2 fixing blocks 25 are rotatably connected to the No. 2 screws 22, and the opposite surfaces of the inner wall of the No. 1 support plate 1 are provided with No. 2 grooves 23, and the inner walls of the two No. 2 grooves 23 are slidably connected to the No. 1 rod 28, and the outer wall of the No. 1 rod 28 is fixedly connected to the No. 2 slider 21, and the top surface of the No. 2 slider 21 is fixedly connected to the No. 2 support plate 15, and the top front and rear of the No. 2 support plate 15 are fixedly connected to two No. 1 fixing blocks 17 near the center line, and the inner walls of the two No. 1 fixing blocks 17 are rotatably connected to the No. 1 screw 19, and the outer wall of the No. 1 screw 19 is threadedly connected to the No. 1 slider 14, and the front end of the outer wall of the No. 1 slider 14 is fixedly connected to the support column 13, and the front end surface of the support column 13 is fixedly connected to the QR code nozzle 12;

[0026] The opposite surfaces of the outer wall of the protruding part of the No. 2 support plate 15 are provided with No. 1 grooves 16, and the outer walls of the two No. 1 grooves 16 are slidably connected with No. 2 rods 29, and the top surface of the No. 2 rod 29 is fixedly connected with two pillars 20. The outer wall of the No. 1 support plate 1 is fixedly connected with a bracket 11 on the side away from the No. 2 axis 24. The front end surface of the bracket 11 is fixedly connected with a base plate 6, and the top surface of the base plate 6 is fixedly connected with three legs 7. The top surfaces of the two front legs 7 among the three legs 7 are fixedly connected with a fixed shaft 8. The outer wall of the fixed shaft 8 is rotatably connected with a sleeve 9, and a heating lamp 10 is movably provided on the inner wall of the sleeve 9. The top surface of the rear leg 7 among the three legs 7 is fixedly connected with a bracket 27.

[0027] Specifically, hold the No. 2 shaft 24 by hand and rotate it, and the No. 2 shaft 24 further drives the No. 2 screw 22 to rotate. The No. 2 screw 22 is subjected to the rotational force and rotates on the inner walls of the two No. 2 fixing blocks 25. Because the No. 1 rod 28 passes through the No. 2 slider 21 and both ends are in the No. 2 grooves 23, the entire No. 2 slider 21 cannot rotate, so the No. 2 slider 21 moves along the No. 2 screw 22, and the movement of the No. 2 screw 22 drives the No. 2 support plate 15 on the top to move together. Hold the No. 1 shaft 18 by hand and rotate it. The rotation of the No. 1 shaft 18 further drives the No. 1 screw 19 on the inner wall to rotate along the inner walls of the two No. 1 fixing blocks 17. Because the No. 2 rod 29 passes through the No. 1 slider 14 and both ends are in the No. 1 grooves 16, the entire No. 1 slider 14 cannot rotate, so the No. 1 slider 14 can only move back and forth along the No. 1 screw 19, and further drive the support column 13 at the front end to move back and forth. The movement of the support column 13 further drives the QR code printhead 12 to move back and forth.

[0028] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4The four table legs 3 are located on both sides in groups of two, and the outer wall of the front table legs 3 of one group is fixedly connected to the motor box 26. The inner wall of each group of table legs 3 is rotatably connected to the rotating shaft 4, and the outer walls of the two rotating shafts 4 are friction-driven with a conveyor belt 2. The top surface of the conveyor belt 2 is movably provided with multiple supporting blocks 5, No. 1 screw 19 is threadedly connected to No. 1 slider 14, and the sleeve 9 is movably connected to the bracket 27. The outer wall of one side of the No. 2 screw 22 is fixedly connected to the No. 2 shaft 24, and the rear end face of the No. 1 screw 19 is fixedly connected to the No. 1 shaft 18. A motor is arranged inside the motor box 26, and the output end of the motor passes through the table leg 3 and is fixedly connected to the rotating shaft 4. The bottom end face of the No. 1 support plate 1 is fixedly connected to four columns 30, and the outer walls of the four columns 30 are slidably connected to sleeve rods 31. The four sleeve rods 31 and the inner walls of the four columns 30 are all provided with fixing holes 33, and the inner walls of multiple fixing holes 33 are movably connected to fixing rods 32, and the lower end faces of the four sleeve rods 31 are equipped with self-locking universal wheels.

[0029] Specifically, the motor inside the motor box 26 starts to work, and the rotation of the motor output end drives the rotating shaft 4 to rotate, and the rotating shaft 4 further drives the conveyor belt 2 on the outer wall to move, and the conveyor belt 2 further drives the support block 5 on the outer wall to move. When passing through the QR code nozzle 12, the internal tag is sprayed with an anti-counterfeiting QR code, and the anti-counterfeiting QR code is dried after passing through the baking lamp 10. Multiple fixed rods 32 are pulled out to adjust the lifting of the No. 1 support plate 1, and the sleeve 9 is flipped to the front along the fixed axis 8. At this time, a part of the front end of the conveyor belt 2 can pass through the bottom of the conveyor belt 2.

[0030] Working principle: Hold the No. 2 shaft 24 and rotate it, the No. 2 shaft 24 drives the No. 2 screw 22 to rotate, the No. 2 screw 22 rotates on the inner wall of the two No. 2 fixed blocks 25, because the No. 2 slider 21 and the No. 2 screw 22 are threadedly connected, and because the No. 1 rod 28 passes through the No. 2 slider 21 and both ends are in the No. 2 groove 23, the No. 2 slider 21 moves along the No. 2 screw 22, and the movement of the No. 2 screw 22 drives the No. 2 support plate 15 on the top to move, so that the No. 2 support plate 15 can move left and right as a whole. Move, hold the No. 1 shaft 18 and rotate it. The rotation of the No. 1 shaft 18 drives the No. 1 screw 19 on the inner wall to rotate on the inner walls of the two No. 1 fixed blocks 17. Because the No. 1 screw 19 is threadedly connected to the No. 1 slider 14, and because the No. 2 rod 29 passes through the No. 1 slider 14 and its two ends are in the No. 1 groove 16, the No. 1 slider 14 moves back and forth along the No. 1 screw 19, and drives the front support column 13 and the QR code printhead 12 to move back and forth. The two pillars 20 provide further support for the No. 1 slider 14;

[0031] Secondly, the motor inside the motor box 26 starts to drive the rotating shaft 4 to rotate, and the rotating shaft 4 drives the conveyor belt 2 on the outer wall to move. The movement of the conveyor belt 2 drives the support block 5 on the outer wall to move, and the baking lamp 10 can bake the anti-counterfeiting QR code inside the support block 5. Multiple fixing rods 32 are pulled out from multiple fixing holes 33, and the four columns 30 drop due to gravity, and drive the No. 1 support plate 1 to drop. The drop of the No. 1 support plate drives the bracket 11 on the right to drop. The bracket 11 drives the bottom plate 6 in the front to drop. The bottom plate 6 drives the three legs 7 on the top to drop. The flip sleeve 9 flips to the front along the fixed axis 8. Because the bottom of the sleeve rod 31 is a universal wheel, it moves backward to allow the baking lamp 10 and other structures to pass under the conveyor belt 2.
