Description

Technical Field

[0001] The present invention relates to the technical field of magnetization devices, and specifically, to an anti-counterfeiting watermark magnetization device for packaging boxes. Background Art

[0002] Traditional anti-counterfeiting technologies, such as laser engraving, two-dimensional codes, etc., although they can effectively improve the security of products, these technologies have gradually been overcome by forgery technologies. In contrast, the anti-counterfeiting watermark magnetization device combines watermark and magnetization technologies. It can not only form an imperceptible watermark pattern on the packaging box, but also through specific magnetization processing, enable these watermark patterns to be verified by professional equipment, increasing the difficulty of anti-counterfeiting. However, there are still some defects in the existing magnetization devices.

[0003] For example, the invention patent with the publication number CN116442647A discloses a magnetization orientation device and operation method for magnetic optical variable effect ink, including a strong magnetic field plate, a chassis, a printed matter conveying mechanism, and a support rail. The left and right ends of the chassis are respectively provided with a feed inlet and a discharge outlet. The printed matter conveying mechanism is installed at the rear side inside the chassis, the support rail is installed on the left side inside the chassis, the strong magnetic field plate is installed on the right side inside the chassis and the upper end surface of the strong magnetic field plate is flush with the upper end surface of the support rail. The strong magnetic field plate can be directly opposite to the position to be magnetized on the printed matter. The printed matter enters from the feed inlet and is sent out from the discharge outlet under the conveying action of the printed matter conveying mechanism. When producing magnetic optical variable ink, this magnetization orientation device can be directly connected between the screen printing machine screen cylinder and the curing drying oven, or connected to the same position between other printing equipment and the curing drying oven to achieve the curing orientation of the magnetic ink, and finally obtain a magnetic optical variable effect ink printing. Although the above device can achieve the optical variable effect, during use, it cannot be conveniently switched between heating and drying and magnetization, and it cannot keep the printing material stationary during magnetization, nor can it make the printing material continue to move when magnetization is completed and drying is carried out.

The third key rod on the second motor drives the fourth key rod to rotate, and the fourth key rod drives the first key rod to rotate. The second gear will cause the first key rod to drive the second key rod to rotate in the opposite direction, so as to drive the upper and lower groups of key sleeves of the device to rotate in opposite directions subsequently. Furthermore, when the device is switched to the drying mode, the printing material can be continuously conveyed, and when it is switched to the magnetization mode, the printing material can be kept stationary, enhancing the adaptability of the device, ensuring the magnetization quality of the device, and solving the problems that the existing magnetization device cannot keep the printing material stationary during the magnetization process and cannot make the printing material move continuously when the magnetization is completed and drying is carried out.

Specific embodiments

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts fall within the scope of protection of the present invention.

[0035] Embodiment 1, as Figures 1-12As shown in the figure, this embodiment proposes an anti-counterfeiting watermark magnetization device for packaging boxes, which includes a printing press body 1. A first connecting plate 2 and a second connecting plate 3 are installed on the printing press body 1. A guide plate 4 is fixedly connected between the first connecting plate 2 and the second connecting plate 3. The first connecting plate 2 and the second connecting plate 3 are used to support the guide plate 4, and the guide plate 4 facilitates the subsequent conveyance of the packaging box cardboard into the device for printing and anti-counterfeiting watermark magnetization processing. A first key rod 11 and a second key rod 12 are rotatably installed on the first connecting plate 2 and the second connecting plate 3. An opening 7 is formed on the printing press body 1. A magnetization plate 6 is slidably installed in the opening 7. A connecting component 8 is installed on the magnetization plate 6. The opening 7 allows the magnetization plate 6 to pass through, so as to perform magnetization processing on the anti-counterfeiting label subsequently. An electric heating plate 9 is installed on the connecting component 8. The electric heating plate 9 can rotate on the magnetization plate 6 through the connecting component 8, so as to realize the storage function subsequently. A telescopic component 19 is arranged between the printing press body 1 and the electric heating plate 9. The telescopic component 19 is used to adjust the positions of the electric heating plate 9 and the magnetization plate 6, so as to switch the functions of the device. A conveying component 10 is installed on the printing press body 1. The first key rod 11 and the second key rod 12 cooperate with the conveying component 10 to convey packaging box cardboard of different widths, enhancing the adaptability of the device. A first sliding plate 13 is slidably installed on the printing press body 1. A second motor 14 is fixedly connected to the first sliding plate 13. A docking component 15 and a supporting component 16 are installed on the first sliding plate 13. Second gears 20 are installed on both the first key rod 11 and the second key rod 12. The second gears 20 can make the first key rod 11 and the second key rod 12 rotate in opposite directions. The docking component 15 and the supporting component 16 keep the position of the printing material unchanged when the device is switched to the magnetization function, and can continuously convey the material when it is switched to the heating and drying function, enhancing the convenience of the device during use.

[0036] Embodiment 2, as Figures 1-12 shown, based on the same concept as the above Embodiment 1, this embodiment also proposes an anti-counterfeiting watermark magnetization device for packaging boxes.

[0037] In this embodiment, the connecting component 8 includes a limiting groove 801 formed on the printing press body 1. A limiting plate 802 is slidably installed in the limiting groove 801. The limiting plate 802 is fixedly connected to the magnetization plate 6. A first connecting block 803 is rotatably installed in the magnetization plate 6. A second connecting block 804 is fixedly connected to the first connecting block 803. The second connecting block 804 is rotatably connected to the electric heating plate 9. Subsequently, after removing the magnetization plate 6 and the electric heating plate 9 as a whole, the storage function can be realized by rotating the electric heating plate 9. The first connecting block 803 rotates in the magnetization plate 6, and the electric heating plate 9 rotates outside the second connecting block 804, thereby reducing the space occupied by the device.

[0038] In this embodiment, the inner wall of the limiting groove 801 is in close contact with the outer wall of the limiting plate 802. The limiting plates 802 are symmetrically distributed on both sides of the magnetization plate 6. The limiting grooves 801 and the limiting plates 802 enable the magnetization plate 6 to move straight in the device, ensuring the stability of the magnetization operation of the device.

[0039] In this embodiment, the conveying assembly 10 includes key sleeves 1003 key-connected to both sides of the first key rod 11 and the second key rod 12. A slip ring 1002 is rotatably installed on the key sleeve 1003. A connection plate 1001 is fixedly connected to the slip ring 1002. The connection plate 1001 is slidably connected to the printing press body 1. A first motor 1005 is installed on the printing press body 1. A first gear 1006 is fixedly connected to the output shaft of the first motor 1005. Rack bars 1004 are meshed and connected to both sides of the first gear 1006. The rack bars 1004 are respectively connected to the connection plates 1001 on both sides of the printing press body 1. The device can drive the first gear 1006 to rotate through the first motor 1005. When the first gear 1006 rotates, it will drive the rack bars 1004 on both sides of it to move towards each other or away from each other, thereby changing the initial positions of the slip rings 1002 and the key sleeves 1003 on both sides of the device, so as to adapt to different sizes of packaging box cardboard for subsequent use.

[0040] In this embodiment, the key sleeve 1003 is made of rubber material, so that the upper and lower groups of key sleeves 1003 of the device can stably hold the packaging box cardboard for conveying. The connection plate 1001, the slip ring 1002 and the rack bar 1004 are fixedly connected into an integral structure to ensure the overall stability of the device. The length of the key sleeve 1003 is less than half of the length of the first key rod 11, ensuring that the two key sleeves 1003 can be adjusted in position on the first key rod 11.

[0041] In this embodiment, an annular groove 17 is formed on the side surface of the slip ring 1002. Mounting blocks 18 are installed in the annular grooves 17 of adjacent slip rings 1002. The upper half and the lower half of the mounting block 18 are both spherical segments. When the upper slip ring 1002 moves left and right, it will drive the lower slip ring 1002 to move left and right synchronously through the mounting block 18 in the annular groove 17, and does not affect the reverse rotation of the upper and lower slip rings 1002, ensuring the stability of the device during operation.

[0042] In this embodiment, the docking assembly 15 includes a third key rod 1501 fixedly connected to the output shaft of the second motor 14. A first connection ring 1502 is fixedly arranged on the first slide plate 13. A fourth key rod 1503 is fixedly connected to the third key rod 1501. A fixed block 1504 is fixedly arranged on the first key rod 11. By driving the third key rod 1501 and the fourth key rod 1503 in the first connection ring 1502 to rotate through the second motor 14, the fourth key rod 1503 facilitates driving the fixed block 1504 to rotate subsequently, so as to convey the printing material.

[0043] In this embodiment, the connection modes between the third key rod 1501 and the fourth key rod 1503 and the first connecting ring 1502 are both rotational connections. A key groove for docking with the fourth key rod 1503 is formed in the fixed block 1504. When the third key rod 1501 and the fourth key rod 1503 are pushed, the fourth key rod 1503 will be docked with the key groove on the fixed block 1504, so that the fixed block 1504 and the third key rod 1501 rotate synchronously, which is convenient for subsequent conveying and stopping the conveying of printing materials when switching different functions.

[0044] In this embodiment, the support assembly 16 includes a first slide rod 1601 fixedly connected to the first slide plate 13. An adapter rod 1602 is fixedly connected to the first slide rod 1601. A second slide rod 1603 is fixedly connected to the adapter rod 1602. A spring 1604 is fixedly connected between the adapter rod 1602 and the printing machine body 1. A pressing plate 1605 is fixedly arranged on the electric heating plate 9. The second slide rod 1603 is slidably connected to the printing machine body 1. After the electric heating plate 9 is moved into the device, the pressing plate 1605 can abut against the adapter rod 1602, so that the adapter rod 1602 pushes the second slide rod 1603 and the first slide rod 1601, and the spring 1604 is compressed. The first slide plate 13 slides on the printing machine body 1, so as to automatically convey printing materials when using the heating function.

[0045] In this embodiment, the telescopic assembly 19 includes a first side plate 1901 and a second side plate 1902 fixedly connected to the lower part of the electric heating plate 9. A chute 5 is formed in the printing machine body 1. An electric push rod 1903 is slidably connected in the chute 5. A fixing plate 1904 is fixedly arranged on the electric push rod 1903. Combining Figure 1 It can be seen that since both sides of the chute 5 are through-port structures, the chute 5 can facilitate the removal or installation of the electric push rod 1903. A second slide plate 1905 is slidably installed on the fixing plate 1904. A communication groove 1906 for docking with the second slide plate 1905 is formed in the electric heating plate 9. The second slide plate 1905 can be moved out from the inside of the communication groove 1906, so that the electric heating plate 9 can be removed from the device. By shortening the electric push rod 1903, the electric heating plate 9 is moved into the device, so that the device switches from the magnetization function to the function of heating and drying printing materials.

[0046] Specifically, the present invention is a packaging box anti-counterfeiting watermark magnetization device. First, as Figures 1-7As shown, the first connecting plate 2 and the second connecting plate 3 on the printing press body 1 are used to support the guide plate 4. The guide plate 4 is used to convey the packaging box cardboard into the device for printing and anti-counterfeiting watermark magnetization treatment. The opening 7 allows the magnetization plate 6 and the electric heating plate 9 to pass through, so as to magnetize the anti-counterfeiting label and perform heating and drying treatment after magnetization. The electric heating plate 9 can rotate on the magnetization plate 6 through the connecting component 8, so as to realize the storage function after removing the magnetization plate 6 and the electric heating plate 9. Since the second connecting block 804 is rotatably connected to the electric heating plate 9, the device can rotate the first connecting block 803 inside the magnetization plate 6 and the electric heating plate 9 outside the second connecting block 804 by rotating the electric heating plate 9 after removing the magnetization plate 6 and the electric heating plate 9 as a whole, thereby reducing the space occupied by the device. Since the limiting plates 802 are symmetrically distributed on both sides of the magnetization plate 6, the telescopic component 19 is used to adjust the positions of the electric heating plate 9 and the magnetization plate 6 and the electric heating plate 9, so as to switch the magnetization or heating and drying function of the device. Shortening the electric push rod 1903 moves the electric heating plate 9 to the inside of the device, switching the device from the magnetization function to the function of heating and drying the printing material. Combined with Figure 1 It can be seen that since both sides of the chute 5 are through-hole structures, the electric push rod 1903 can be removed or installed on the printing press body 1, and the second sliding plate 1905 can be removed from the inside of the connecting groove 1906, so that the electric heating plate 9 can be removed from the device.

[0047] As Figures 3-12 shown, the first key rod 11 and the second key rod 12 cooperate with the conveying component 10 to enable the device to convey packaging box cardboard of different widths. The first motor 1005 drives the first gear 1006 to rotate. When the first gear 1006 rotates, it will drive the racks 1004 on both sides of the first gear 1006 to move towards or away from each other, thereby changing the initial positions of the slip rings 1002 and the key sleeves 1003 on both sides of the device. When the upper slip ring 1002 moves left and right, it will drive the lower slip ring 1002 to move left and right synchronously through the mounting block 18 in the annular groove 17, and does not affect the reverse rotation of the upper and lower slip rings 1002. By changing the positions of the slip rings 1002 and the key sleeves 1003 on both sides, the device is adapted to convey packaging box cardboard of different sizes. The second motor 14 drives the third key rod 1501 and the fourth key rod 1503 in the first connecting ring 1502 to rotate. The fourth key rod 1503 facilitates driving the fixed block 1504 to rotate later. And when the first key rod 11 rotates, the second gear 20 can make the first key rod 11 and the second key rod 12 rotate in opposite directions, so that the device can stably convey the printing material. The docking component 15 and the support component 16 enable the device to keep the position of the printing material unchanged when switching to the magnetization function and continuously convey the material when switching to the heating and drying function. As Figure 10As shown in the figure, by shortening the electric push rod 1903, the electric heating plate 9 is moved to the inside of the device, so that the device switches from the magnetization function to the function of heating and drying the printing material. During this process, the pressing plate 1605 will abut against the connecting rod 1602, causing the connecting rod 1602 to push the second sliding rod 1603 and the first sliding rod 1601, and the spring 1604 is compressed. The first sliding plate 13 slides on the printing press body 1, as Figure 4 shown in the figure, when the third key rod 1501 and the fourth key rod 1503 are pushed, the fourth key rod 1503 is docked with the key groove in the fixed block 1504, so that the fixed block 1504 and the third key rod 1501 rotate synchronously, enabling the device to continuously convey the printing material when magnetization is completed and drying is carried out. The first side plate 1901 and the second side plate 1902 are used to block the opening 7, thereby improving the heating and drying effect of the device.

[0048] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
