Magnetic printing is used in a wide range of fields. For example, magnetic cards can be used for train tickets, monthly passes, stamps, bank passbooks, and ID cards. Magnetic films are used on price cards, and magnetic ink can also be used to print items such as amounts on registration forms and checks. In short, the applications of magnetic printing are becoming increasingly widespread.

[0003] During the production of magnetic ink printed products, the magnetic material in the ink must be positioned and magnetized before drying and curing to ensure the clarity of the printed images and text, as well as the accuracy of the printed text's orientation. Existing production technologies place high demands on both raw materials and equipment. The raw materials used in ink formulations are particularly expensive, and the cost of retrofitting production equipment is also substantial. Magnetic positioning equipment can cost hundreds of thousands or even millions of yuan, and its use is of no benefit beyond the production of this material. This represents an additional burden for printing manufacturers, whose annual revenue from operations cannot keep up with the equipment depreciation costs, hindering the widespread adoption of this process.

[0023] The present invention will be further described below with reference to specific embodiments.

[0024] Example 1: Figure 1-3As shown, a magnetization orientation device for magnetic optically variable effect ink includes a strong magnetic field plate 1, a chassis 2, a printed matter conveying mechanism and a support rail 3. The left and right ends of the chassis 2 are respectively provided with a feed port 4 and a discharge port 5. The printed matter conveying mechanism is installed on the rear side of the chassis 2, the support rail 3 is installed on the left side of the chassis 2, the strong magnetic field plate 1 is installed on the right side of the chassis 2 and the upper end surface of the strong magnetic field plate 1 is flush with the upper end surface of the support rail 3. The strong magnetic field plate 1 can face the position to be magnetized on the printed matter 9. The printed matter 9 is lowered by the conveying action of the printed matter conveying mechanism and the printed matter enters from the feed port 4 and is sent out from the discharge port. When producing magnetic optically variable ink, this magnetization orientation device can be directly connected between the screen cylinder of the silk screen printing machine and the curing drying tunnel, or connected to the same position of other printing equipment and the curing drying tunnel to realize the curing orientation of the magnetic ink, and finally obtain a magnetic optically variable effect ink printing; the ink coloring particles are pre-magnetic and are randomly arranged before magnetization and orientation, so the colors presented are chaotic and irregular. After magnetic pole orientation, the same color is in the same direction, so this effect occurs.

[0025] The printing material conveying mechanism in this embodiment includes a conveyor belt 10 and an elastic pressing mechanism. The conveyor belt 10 is installed on the chassis 2, and the upper end surface of the conveyor belt 10 is flush with the upper surface of the support rail 3. A fitting support plate 11 is installed at the bottom of the upper belt horizontal section of the conveyor belt 10. The elastic pressing mechanism is installed above the conveyor belt 10 and can clamp the printed material. The elastic pressing mechanism elastically squeezes one side of the printed material onto the belt of the conveyor belt and relies on the support of the support plate to work. The elastic extrusion has better stability. The belt of the conveyor belt 10 is sleeved on the driving roller and the driven roller. The driving roller and the driven roller are rotatably connected to the belt frame at both ends. The belt frame is fixedly connected to the chassis. After one end of the rotating shaft of the driving roller extends out, it is connected to the driving motor 19 through a synchronous belt transmission mechanism. The driving motor 19 is fixedly connected to the chassis 2. The pressing mechanism includes a mounting plate 12, a telescopic rod 13 and a compression spring 14. A plurality of evenly arranged balls 15 protruding from the bottom surface of the mounting plate 12 are installed at the bottom of the mounting plate 12. The balls 15 can also be replaced by rollers. The telescopic rod 13 adopts multiple roots, and the lower end is fixedly connected to the upper surface of the mounting plate 12. The upper end of the telescopic rod 13 is movable through the fixing plate 16 and is screwed with a nut 17. The fixing plate 16 is fixedly connected to the rear side wall of the chassis 2. The compression spring 14 is sleeved on the telescopic rod 13, wherein the upper and lower ends of the compression spring 14 respectively abut against the fixing plate 16 and the mounting plate 12. Under the extrusion action of the compression spring, the balls can elastically squeeze the printed matter into close contact with the belt surface of the belt conveyor (and facing the support plate), and under the friction conveying of the belt conveyor, the printed matter can be quickly conveyed to avoid poor conveying accuracy caused by slipping. By adopting multiple telescopic rods, the elastic compression is stable and reliable, and the directional telescopic stability is better.

[0026] In order to facilitate the directional and precise movement of printed materials, in this embodiment, a row of guide wheels 18 are installed on the rear side of the above-mentioned conveyor belt machine 10. The guide wheels 18 are against the rear side of the printed materials 9. The guide wheels are rotatably connected to the frame of the conveyor belt machine. An annular V-shaped groove is provided in the middle of the guide wheel cylinder to facilitate the limitation of this side of the printed material, thereby obtaining a printed material with directional movement.

[0027] In order to make the transported printed materials as close to the side of the conveyor belt as possible, in this embodiment, the above-mentioned support track 3 is tilted 1-3 degrees toward the side of the printed material conveying mechanism. The support track is arranged at an angle, and the printed materials will tilt toward the west side of the printed material conveying mechanism and move in a directional manner under the abutment of the side guide wheel, thereby realizing the magnetization orientation of the magnetic ink printed at the specified position of the printed material, and obtaining a precise magnetization orientation effect.

[0028] Among them, in this embodiment, the above-mentioned support rail 3 includes multiple square tubes 301, threaded rods 302 and double nuts 303. The length direction of the multiple square tubes 301 is toward the entry and exit direction of the chassis 2 and is evenly arranged along the front and rear direction of the chassis 2. At least two threaded rods 302 are used, and after passing through the multiple square tubes 301, double nuts 303 are used to lock each square tube 301. The support rail uses stainless steel pipes to form a grid structure, and the support is stable and reliable. A positioning block is detachably fixedly connected to the support rail 3, which is convenient for position limitation of printed materials of different widths.

[0029] In order to orient the magnetization at different positions, in this embodiment, the above-mentioned strong magnetic field plate 1 is slidably connected to the bottom of the chassis 2 through two pairs of slider guide pairs 6, and a manual linear module 7 is installed between the two pairs of slider guide pairs 6. The two pairs of slider guide pairs 6 are arranged perpendicular to the walking direction of the printed matter 9. The slider of the manual linear module 7 is fixedly connected to the bottom of the strong magnetic field plate 1, and the operating handle 8 of the manual linear module 7 is located outside the chassis 2. The strong magnetic field plate is driven to move laterally by the manual linear module, thereby realizing the precise position adjustment of the strong magnetic field plate, and the adjustment is fast. The manual linear module relies on two guide rods and linear guides to realize the directional movement of the slider, and a screw nut pair is used to drive the slider to move, thereby realizing the precise position adjustment of the manual linear module.

[0030] Principle of use: The printed matter enters from the feed port, is squeezed on one side by the printed matter conveying mechanism (providing conveying power), and is sent to the top of the strong magnetic field plate under the support of the support track. If it is for different printed matters, the position of the strong magnetic field plate is adjusted to achieve different magnetization orientations of the printed matters. The strong magnetic field plate magnetizes and orients the magnetic ink areas on the printed matters that need to be magnetized, and the printed matters are sent out from the discharge port.

[0031] The specific operation process of the magnetization and orientation device is as follows: the front-end equipment prints magnetic optically variable effect ink → transports it into the magnetization and orientation device of this application → adjusts the position, locates and fixes the magnetism → transports it to the UV drying tunnel → collects the paper. The specific working process is as follows: After the paper is printed with magnetic ink, it is clamped and fed in between the conveyor belt and the pressing ball, and then fed into the fixed magnetic field (magnetization orientation) of the strong magnetic field plate through the paper feeding support slide rail through the belt. The ball rolls and squeezes toward the side end of the paper (printed material), guiding the printed paper to align with the side rule or guide wheel. The printed paper is transported to the magnetic field plate of the strong magnet for fixed magnetism, and then transported out through the conveyor belt and enters the UV drying tunnel for drying and curing. During this process, it is dried by the UV drying system. Finally, it is unloaded and collected by the paper collection device to complete the printing process.

[0032] The main advantages of the magnetization orientation device of the present invention are as follows:

[0033] 1) The equipment cost is low. A printing manufacturer only needs to invest no more than RMB 10,000 in a full set of equipment to produce exquisite graphics and texts using magnetic optically variable anti-counterfeiting inks. This makes the process suitable for promotion and application within the industry. It also broadens the functions of existing printing equipment.

[0034] 2) Easy to operate. Production staff can start operating it immediately after a brief training. It is not as complicated as other special equipment. Its production efficiency is high, with an average speed of 3500-4000 sheets / hour, which can meet the needs of large-scale product production;

[0035] 3) Stable fixed magnetization and accurate overprinting direction: The position of the strong magnetic field is adjusted by the screw and nut of the manual linear module. The forward and backward positions can be accurately adjusted to ±0.15mm per revolution. The strong magnetic field plate is fixed to the slider of the manual linear module. After debugging before formal production, the position of the fixed magnetization equipment and the printing position are fixed. In addition, the paper is guided by the belt and ball bearings before entering the fixed magnetization position, and is aligned with the side gauge baffle (or guide wheel), ensuring smooth paper feed. The fixed magnetization time, fixed magnetization distance, and fixed magnetization position of the product are controlled by the on / off, acceleration, and deceleration of the belt motor, ensuring consistent final product quality.

[0036] 4) During the process of printing and before drying, magnetic ink has a strong adsorption effect on dust particles in the environment, which will cause the image and text to be dirty and dark. The invention adopts a closed chassis for magnetization, so that the entire process is sealed and protected, isolating it from direct contact with the external environment, and the printing quality is very stable.

[0037] 5) The present invention improves the appearance design of the packaging and adds its anti-counterfeiting function, which is conducive to the promotion and application of this technology in the industry.
