[0002] Printed materials are various printed products, and are a general term for various finished products produced using printing technology. In daily life, newspapers, books, magazines, maps, posters, advertisements, and packaging boxes that people come into contact with all fall into the category of printed materials. During the printing process, in order to prevent the printed products from being maliciously copied, anti-counterfeiting labels are generally printed on their products.

[0003] An adjustable printing device is disclosed in a Chinese utility model patent with publication number CN219706424U, which relates to the technical field of printing equipment, and includes a base plate and two vertical plates symmetrically fixedly arranged on the upper surface of the base plate, a first rotating rod is rotatably sleeved between the two vertical plates, a printing roller is fixedly sleeved on the rod wall of the first rotating rod, a printing ring is sleeved on the outside of the printing roller, a lifting mechanism is arranged on the upper surface of the base plate and is connected to a U-shaped plate through the lifting mechanism.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the driven roller in the above-mentioned device can only rotate when driven by the printing ring. During the production process, the driven roller needs to be pressed against the printing ring so that the printing ring can drive the driven roller to rotate.

[0007] By adopting the above technical solution, when the staff needs to print a document, the staff needs to wind the printed document onto the driven roller. Subsequently, the staff starts the first motor, thereby rotating the output shaft of the first motor, so that the threaded rod rotates under the action of the output shaft of the first motor, and then the U-shaped frame moves under the action of the threaded rod, so that the driven roller and the printing ring are pressed tightly. At this time, the staff needs to start the driving device, thereby rotating the output shaft of the driving device, so that the first rotating rod rotates under the action of the output shaft of the driving device, and then the printing ring rotates under the action of the first rotating rod. In this process, the second rotating rod rotates under the action of the linkage assembly, and then the driven roller rotates under the action of the second rotating rod. When in use, the printing ring and the driven roller rotate at the same time, thereby reducing the probability of the driven roller and the printing ring slipping, thereby reducing the probability of blurred printed patterns.

[0008] Furthermore, one end of the first rotating rod away from the driving device passes through the support plate, one end of the second rotating rod passes through the U-shaped frame and the support rod, the linkage assembly includes a fixed plate fixedly set on the side wall of the support plate, and a through hole is opened on the upper surface of the fixed plate. The linkage assembly also includes a first bevel gear fixedly set on the side wall of the first rotating rod, a movable rod rotatably set in the through hole, a second bevel gear installed on the upper surface of the movable rod, a third bevel gear installed on the bottom surface of the movable rod, and a fourth bevel gear fixedly set on the side wall of the second rotating rod, the first bevel gear and the second bevel gear are meshed with each other, and the third bevel gear and the fourth bevel gear are meshed with each other.

[0009] By adopting the above technical solution, when the first rotating rod rotates, the first bevel gear rotates synchronously with the first rotating rod, and then the second bevel gear rotates under the action of the first bevel gear, so that the movable rod and the third bevel gear rotate synchronously with the second bevel gear, and then the fourth bevel gear rotates under the action of the third bevel gear, so that the second rotating rod rotates synchronously with the fourth bevel gear, and then the driven roller rotates under the action of the second rotating rod. When in use, the printing ring and the driven roller rotate at the same time, thereby reducing the probability of slipping between the driven roller and the printing ring, thereby reducing the probability of blurred printed patterns.

[0010] Furthermore, a slide groove is penetrated on the side wall of one of the support plates, an L-shaped rod is slidably arranged in the slide groove, the second rotating rod penetrates the L-shaped rod and is rotatably connected thereto, and the movable rod penetrates the L-shaped rod and is rotatably connected thereto.

[0011] Furthermore, the movable rod includes a sleeve rotatably set in the through hole, and a sleeve rod slidably set in the sleeve, the upper surface of the sleeve is fixed to the second bevel gear, the bottom surface of the sleeve rod is fixed to the third bevel gear, and the sleeve rod passes through the L-shaped rod and is rotatably connected thereto.

[0012] By adopting the above technical solution, when the U-shaped frame moves, the L-shaped rod rotates under the action of the U-shaped frame, thereby causing the sleeve rod to slide under the action of the L-shaped rod. In this process, the probability of the third bevel gear and the fourth bevel gear being separated from each other when the U-shaped frame moves is reduced, thereby improving the stability of the device.

[0013] Furthermore, an annular groove is provided on the inner wall of the through hole, an annular block is rotatably arranged in the annular groove, and the annular block and the sleeve are fixed to each other.

[0014] By adopting the above technical solution, when the sleeve rotates, the annular block rotates with the sleeve. During this process, the side wall of the annular block abuts against the inner wall of the annular groove, thereby reducing the probability of the sleeve and the fixed plate separating from each other when the L-shaped rod moves, thereby improving the stability of the device.

[0015] Furthermore, a limiting groove is provided on the inner wall of the sleeve, a limiting block is slidably arranged in the limiting groove, and a side wall of the limiting block is fixed to a side wall of the sleeve rod.

[0016] By adopting the above technical solution, the limit block reduces the probability of relative rotation between the sleeve and the sleeve rod when the sleeve rod rotates, thereby making the sleeve rotate synchronously with the sleeve rod, thereby improving the stability of the device.

[0017] Furthermore, blocking grooves are provided on the side walls of the two support plates that are close to each other, and blocking rods are slidably arranged in the two blocking grooves, and the blocking rods are fixed to the U-shaped frame.

[0018] By adopting the above technical solution, the blocking rod reduces the probability that the L-shaped rod follows the threaded rod to rotate, thereby improving the stability of the device.

[0020] 1. In the present application, when the staff needs to print a document, the staff needs to wind the printed document onto the driven roller.

At this time, the staff needs to start the driving device, and then the output shaft of the driving device rotates, so that the first rotating rod rotates under the action of the output shaft of the driving device, and then the printing ring rotates under the action of the first rotating rod. In this process, the second rotating rod rotates under the action of the linkage assembly, and then the driven roller rotates under the action of the second rotating rod.

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0029] like Figure 1-4 As shown, the embodiment of the present application discloses an adjustable anti-counterfeiting printing device, including a bottom plate 1, a first motor 11, a support plate 12, a first rotating rod 13, a printing ring 14, a threaded rod 15, a U-shaped frame 16, a second rotating rod 17, a driven roller 18, a driving device 19, a linkage assembly 3, an L-shaped rod 4 and a ring block 6. The bottom plate 1 is a rectangular plate-shaped structure, and the first motor 11 is fixedly arranged on the upper surface of the bottom plate 1, and the axis of its output shaft is vertical. The support plate 12 is a rectangular plate-shaped structure, and the support plate 12 is provided with two and symmetrically installed on the upper surface of the bottom plate 1. The first rotating rod 13 is a round rod-shaped structure, and its axis is horizontal. The two ends of the first rotating rod 13 are respectively rotatably arranged on the side walls of the two support plates 12 close to each other. The printing ring 14 is fixedly arranged on the outer wall of the first rotating rod 13, and its axis coincides with the axis of the first rotating rod 13. The threaded rod 15 is fixedly arranged at the end of the output shaft of the first motor 11, and its axis coincides with the axis of the output shaft of the first motor 11. The cross section of the U-shaped frame 16 is U-shaped, and the U-shaped frame 16 is threadedly connected to the outer wall of the threaded rod 15. The second rotating rod 17 is a round rod structure with a horizontal axis. The two ends of the second rotating rod 17 are respectively rotatably arranged on the side walls of the U-shaped frame 16 that are close to each other in the vertical direction. The driven roller 18 is fixedly arranged on the outer wall of the second rotating rod 17, and its axis coincides with the axis of the second rotating rod 17. The driving device 19 is fixedly arranged on the side wall of one of the support plates 12 away from the other support plate 12, and the axis of its output shaft coincides with the axis of the first rotating rod 13. The output shaft of the driving device 19 is fixed to the side wall of the first rotating rod 13.

[0030] When the staff needs to print a document, the staff needs to wind the printed document onto the driven roller 18. Subsequently, the staff starts the first motor 11, and then the output shaft of the first motor 11 rotates, so that the threaded rod 15 rotates under the action of the output shaft of the first motor 11, and then the U-shaped frame 16 moves under the action of the threaded rod 15, so that the driven roller 18 and the printing ring 14 are pressed tightly. At this time, the staff needs to start the driving device 19, and then the output shaft of the driving device 19 rotates, so that the first rotating rod 13 rotates under the action of the output shaft of the driving device 19, and then the printing ring 14 rotates under the action of the first rotating rod 13. In this process, the second rotating rod 17 rotates under the action of the linkage component 3, and then the driven roller 18 rotates under the action of the second rotating rod 17. When in use, the printing ring 14 and the driven roller 18 rotate simultaneously, thereby reducing the probability of the driven roller 18 and the printing ring 14 slipping, thereby reducing the probability of the printed pattern being blurred.

[0031] One end of the first rotating rod 13 away from the driving device 19 passes through the support plate 12, and one end of the second rotating rod 17 passes through the U-shaped frame 16 and the support rod. The linkage assembly 3 is arranged on the support plate 12, and is used to control the rotation of the second rotating rod 17. The linkage assembly 3 includes a fixed plate 31, a first bevel gear 32, a second bevel gear 33, a third bevel gear 34 and a fourth bevel gear 35. The fixed plate 31 is a rectangular plate structure, and the fixed plate 31 is fixedly arranged on the side wall of the support plate 12. The upper surface of the fixed plate 31 is penetrated by a through hole 2. The first bevel gear 32 is fixedly arranged on the side wall of the first rotating rod 13, and its axis coincides with the axis of the first rotating rod 13. The movable rod 5 is rotatably arranged in the through hole 2, and its axis is vertical. The second bevel gear 33 is installed on the upper surface of the movable rod 5, and its axis coincides with the axis of the movable rod 5. The first bevel gear 32 and the second bevel gear 33 are meshed with each other. The third bevel gear 34 is installed on the bottom surface of the movable rod 5, and its axis coincides with the axis of the movable rod 5. The fourth bevel gear 35 is fixedly disposed on the side wall of the second rotating rod 17 , and its axis coincides with the axis of the second rotating rod 17 . The third bevel gear 34 and the fourth bevel gear 35 are meshed with each other.

[0032] When the first rotating rod 13 rotates, the first bevel gear 32 rotates synchronously with the first rotating rod 13, and then the second bevel gear 33 rotates under the action of the first bevel gear 32, so that the movable rod 5 and the third bevel gear 34 rotate synchronously with the second bevel gear 33, and then the fourth bevel gear 35 rotates under the action of the third bevel gear 34, so that the second rotating rod 17 rotates synchronously with the fourth bevel gear 35, and then the driven roller 18 rotates under the action of the second rotating rod 17. When in use, the printing ring 14 and the driven roller 18 rotate simultaneously, thereby reducing the probability of slipping between the driven roller 18 and the printing ring 14, thereby reducing the probability of blurred printed patterns.

[0033] A slide groove 21 is penetrated through the side wall of one of the support plates 12, and the cross-section of the L-shaped rod 4 is L-shaped. The L-shaped rod 4 is slidably set in the slide groove 21, the second rotating rod 17 penetrates the L-shaped rod 4 and is rotatably connected thereto, and the movable rod 5 penetrates the L-shaped rod 4 and is rotatably connected thereto.

[0034] The movable rod 5 includes a sleeve 51 and a sleeve rod 52. The sleeve 51 is a round rod structure with an open lower end. The upper surface of the sleeve 51 is fixed to the second bevel gear 33. The sleeve rod 52 is a round rod structure. The sleeve rod 52 is slidably arranged in the sleeve 51. The bottom surface of the sleeve rod 52 is fixed to the third bevel gear 34. The sleeve rod 52 passes through the L-shaped rod 4 and is rotatably connected thereto.

[0035] When the U-shaped frame 16 moves, the L-shaped rod 4 rotates under the action of the U-shaped frame 16, so that the sleeve rod 52 slides under the action of the L-shaped rod 4. In this process, the probability of the third bevel gear 34 and the fourth bevel gear 35 being separated from each other when the U-shaped frame 16 moves is reduced, thereby improving the stability of the device.

[0036] An annular groove 22 is formed on the inner wall of the through hole 2 . The annular block 6 is a circular ring structure. The annular block 6 is rotatably disposed in the annular groove 22 . The annular block 6 and the sleeve 51 are fixed to each other.

[0037] When the sleeve 51 rotates, the annular block 6 rotates with the sleeve 51. During this process, the side wall of the annular block 6 abuts against the inner wall of the annular groove 22, thereby reducing the probability of the sleeve 51 and the fixed plate 31 separating from each other when the L-shaped rod 4 moves, thereby improving the stability of the device.

[0038] In order to improve the stability of the device, a limiting groove 23 is provided on the inner wall of the sleeve 51, and a limiting block 7 is slidably arranged in the limiting groove 23, and the side wall of the limiting block 7 is fixed to the side wall of the sleeve rod 52. The limiting block 7 reduces the probability of relative rotation between the sleeve 51 and the sleeve rod 52 when the sleeve rod 52 rotates, thereby making the sleeve 51 rotate synchronously with the sleeve rod 52, thereby improving the stability of the device.

[0039] In order to improve the stability of the device, blocking grooves 24 are provided on the side walls of the two support plates 12 that are close to each other, and blocking rods 8 are slidably arranged in the two blocking grooves 24, and the blocking rods 8 are fixed to the U-shaped frame 16. The blocking rods 8 reduce the probability that the L-shaped rod 4 follows the rotation of the threaded rod 15, thereby improving the stability of the device.

[0040] The use principle of an adjustable anti-counterfeiting printing device in this embodiment is as follows: when the staff needs to print a document, the staff needs to wind the printed document onto the driven roller 18. Then, the staff starts the first motor 11, and then the output shaft of the first motor 11 rotates, so that the threaded rod 15 rotates under the action of the output shaft of the first motor 11, and then the U-shaped frame 16 moves under the action of the threaded rod 15, so that the driven roller 18 and the printing ring 14 are pressed tightly. At this time, the staff needs to start the driving device 19, so that the output shaft of the driving device 19 rotates, so that the first rotating rod 13 rotates under the action of the output shaft of the driving device 19, and then the printing ring 14 rotates under the action of the first rotating rod 13. In this process, when the first rotating rod 13 rotates, the first bevel gear 32 rotates synchronously with the first rotating rod 13, so that the second bevel gear 33 rotates under the action of the first bevel gear 32, so that the movable rod 5 and the third bevel gear 34 rotate synchronously with the second bevel gear 33, and then the fourth bevel gear 35 rotates under the action of the third bevel gear 34, so that the second rotating rod 17 rotates synchronously with the fourth bevel gear 35, and then the driven roller 18 rotates under the action of the second rotating rod 17. When in use, the printing ring 14 and the driven roller 18 rotate simultaneously, thereby reducing the probability of slipping between the driven roller 18 and the printing ring 14, thereby reducing the probability of blurred printed patterns.

[0041] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
