[0001] The invention relates to the technical field of anti-counterfeiting, and in particular to a magnetic fixing device and method for a 3D magnetic optically variable pigment image. Background Art

[0002] Printing magnetic ink on paper, plastic and other substrates, then using permanent magnets or electromagnets to magnetically orient it, then pre-curing it to lock the effect, and finally curing it to increase strength and adhesion, can make the printed product form a cool anti-counterfeiting effect. Currently, there are single bright line, double bright line, ring, star ring, ball and other effects.

[0003] For example, patent CN202111498899.0 discloses a method and printing equipment for printing patterns of magnetic pigments, wherein magnetic ink is applied to the surface of a substrate, wherein the magnetic ink includes a binder and a magnetically oriented optically variable pigment, and the mass ratio of the binder to the optically variable pigment is less than 1.7; the optically variable pigment in the magnetic ink is oriented by a magnetic orientation device to form a magnetic orientation pattern with a three-dimensional effect in the magnetic ink, wherein the magnetic axis direction of the magnet in the magnetic orientation device is parallel to the substrate in space; infrared curing magnetic ink. The printing method of this patent is simple to operate, the printed pattern is full, and the transition between light and dark areas is soft, which provides more options for 3D fixed magnetic color change, and it mainly produces color-changing patterns through different optically variable pigments.

[0004] However, the currently disclosed technology and effects still lack the effect of curve dazzling, so this is also the technical problem to be studied and solved by the present invention. Summary of the invention

[0005] The object of the present invention is to provide a magnetic fixing device and method for forming a 3D magnetic optically variable pigment image with an S-shaped dynamic curve.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0007] The first solution provided by the present invention is: a magnetic fixing device for 3D magnetic optically variable pigment images, comprising a base plate, on which at least one group of magnetic components is arranged, the magnetic component is composed of two parallel elliptical magnets, and a certain distance is set between the two elliptical magnets, one of which has an N pole facing upward and the other has an S pole facing upward; a partition is arranged above the magnetic component, and two hooks made of pure iron, silicon steel or Permalloy are arranged on the partition, and the two hooks are inward-buckled or tangential structures.

[0008] Furthermore, when the two hooks are inwardly buckled or tangent to each other, the distance between the hook tips of the two hooks is 30-40 mm.

[0009] Furthermore, the bottom plate is an iron plate, and the partition is a bakelite plate or an acrylic plate.

[0010] The second solution provided by the present invention is: a magnetic fixing device for 3D magnetic photovariable pigment images, comprising a base plate, a group of hooks made of pure iron, silicon steel or Permalloy, and a group of elliptical magnets, one side of the base plate is provided with at least one group of elliptical grooves for installing the elliptical magnets, and the other side of the base plate is provided with at least one group of grooves for installing the hooks. When the elliptical magnets are installed on the base plate, one of the elliptical magnets has its N pole facing upward and the other has its S pole facing upward, and the two hooks are inwardly buckled or tangent structures.

[0011] Furthermore, when the two hooks are inwardly buckled or tangent to each other, the distance between the hook tips is 30-40 mm.

[0012] Furthermore, through holes are provided in the elliptical grooves or recessed grooves.

[0013] Furthermore, the device also includes end covers, which are respectively arranged above the hook and below the elliptical magnet.

[0014] Furthermore, the bottom plate is provided with a plurality of groups of elliptical grooves arranged in a straight line, and correspondingly, the other side of the bottom plate is provided with a plurality of groups of grooves arranged in a straight line, and each group of elliptical grooves and the grooves are provided with elliptical magnets and hooks respectively.

[0015] Furthermore, the bottom plate is provided with a plurality of groups of elliptical grooves in the horizontal and vertical directions respectively, and correspondingly, a plurality of groups of grooves are also provided in the horizontal and vertical directions on the other side of the bottom plate, and each group of ellipses and grooves is provided with an elliptical magnet and a hook accordingly.

[0016] Furthermore, the thickness of the end cover is 1 mm-5 mm, and the end cover is mounted on the base plate by screws.

[0018] The magnetization device and method of the present invention can form a comprehensive effect of S-shaped dynamic curves and rolling bright lines, which is more diverse than the single bright lines, double lines, circular rings, star rings, and spherical beads in the past. After the substrate printed with magnetic ink is magnetized, pre-cured, and fully cured by the magnetization method of the present invention, when the magnetization effect is flipped up and down along the Y-axis direction, the S-shaped curve changes left and right along the X-axis direction, rather than changing up and down along the Y-axis, and a wide bright line effect is formed on both sides. This is a one-time printing and one-time magnetic orientation to form two effects at the same time, and this comprehensive effect is very unique. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0072] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and the like are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", and the like may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0073] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0074] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0075] The present invention utilizes two elliptical magnets, one with the N pole facing upwards and the other with the S pole facing upwards. The two magnets have a certain spacing, which is determined by two hook-shaped hooks made of pure iron and silicon steel permalloy; the hooks can be selected according to actual needs, and the spacing between the magnets can be between 10-56mm, but the spacing between the magnets is more reasonable between 30-40mm; the two hooks are inwardly buckled and placed above the two magnets. The spacing between the hook tips between the inward buckles is different, so the shape and size of the resulting S-shaped dynamic fixed magnetization effect are also different; the distance between the hook tips can be 0-11mm, and the effective hook tip spacings made in this example are 3mm, 4mm, and 5mm respectively. Since the magnet will have a force on it, in order to prevent the hook from sinking, a partition is placed between the hook and the magnet. The hook and the magnet are in orthogonal directions, and of course, tilted placement will also form such an effect, but in order to facilitate placement, an orthogonal form is adopted. Placing the printed magnetic ink substrate on the hook will form an S-shaped curve 3D dynamic effect, and using a curing lamp to pre-curing lock effect, when the substrate is turned upside down, the S-shaped curve will dynamically change along the left and right directions, and a bright line effect will be formed on both sides of the S-shaped curve. It can be seen that the method of the present invention can make the substrate printed with magnetic ink form a unique comprehensive effect, which has a high anti-counterfeiting identification value. Figure 1 The spatial relationship between the hook, the partition and the magnet shown (inward buckling mode). When the two hooks are tangent, an S-shaped fixed magnet effect can also be formed, but the S-shaped volume is relatively large and extends outward.

[0076] Embodiment 1:

[0077] 1) Prepare a bottom plate 1. In this embodiment, the bottom plate 1 is an iron plate with a width of more than 100 mm, which is wider than the length of the ellipsoidal magnet 2 (the current length of the ellipsoidal magnet is 100 mm), about 300 mm in length, and 3-5 mm in thickness.

[0078] 2) Prepare two elliptical magnets 2, the size of which is 100X10X16 (mm) (length, width and height).

[0079] 3) Place two elliptical magnets 2, one with the N pole facing upwards and the other with the S pole facing upwards, adsorb the two elliptical magnets on the iron plate, align them parallel, and place them with a center line distance of 40mm and an interval of 30mm.

[0080] 4) Place a 1mm thick bakelite board or acrylic board on the elliptical magnet as a partition 3, with a length and width of 50mm and 80mm.

[0081] 5) Place two hooks 4 made of pure iron, silicon steel or Permalloy on the bakelite board or acrylic board. The hooks are attracted by the magnet but can be adjusted. Adjust the positions of the two hooks to make them orthogonal to the ellipsoidal magnet. The two hooks are buckled inwards, and the distances between the hook tips are 3mm, 4mm and 5mm respectively.

[0086] 10) By comparison, we know that: when the distance between the substrate and the hook is constant, the shorter the distance of the hook tip, the larger the S size of the S-shaped fixed magnetic effect, and vice versa.

[0087] Embodiment 2:

[0088] In this embodiment, the bottom plate 1 is an aluminum block. Two elliptical grooves 11 are dug out on one side of the aluminum block for placing elliptical magnets.

Two hook-shaped grooves 14 are opened on the center line of the other side of the elliptical groove 11 of the aluminum block for placing two hooks 4 made of pure iron, silicon steel or permalloy, and the hooks 4 can be buckled inward. Two through holes 12 are opened on the hooks of the two grooves 14 for ejecting the hooks by ejector pins when taking out the hooks; the two hook-shaped grooves can be set to make the hook tip spacing 3mm, 4mm, 5mm as needed. This side is also provided with an end cap. The aluminum block is provided with screw holes for fixing the end caps. The thickness of the end cap 5 can be set to 1mm, 2mm, 3mm, 5mm as needed. Threaded holes are set on both sides of the center line of the aluminum block for fixing the aluminum block during installation. This assembly consisting of a magnet and a hook made of pure iron or silicon steel is called a magnetic assembly.

[0109] Embodiment 4:

[0110] In this embodiment, the bottom plate 1 is an aluminum block. Two elliptical grooves 11 are dug out on one side of the aluminum block for placing the elliptical magnet 2. Two threaded holes or through holes 12 are opened in the elliptical grooves 11 for pushing out the elliptical magnet by screws or push rods when removing the magnet. This side is provided with an end cover 5. The aluminum block has threaded holes 13 to fix the end cover to prevent the elliptical magnet 2 from falling. Two hook-shaped grooves 14 are opened on the center line of the other side of the aluminum block for placing two hooks made of pure iron, silicon steel or Permalloy, and the hooks can be tangent to each other, and the spacing between the tangent hook tips is 0mm, 1mm, and 2mm; two through holes 12 are opened on the hook handles and hooks of the two grooves 14 for pushing out the hooks with a push rod when taking out the hooks; the two hook-shaped grooves can be set to make the hook tip spacing 3mm, 4mm, and 5mm as needed. This side is also provided with an end cover, and there are screw holes on the end cover for fixing the end cover. The thickness of the end cover can be set to 3mm, 5mm, and 6mm as needed. The four corners of the aluminum block are provided with through holes for fixing the aluminum block during installation. This assembly consisting of hooks with magnets, pure iron, silicon steel or Permalloy is called a magnetic assembly. The assembly diagram of this magnetic assembly is shown in Figure 6 As shown, the hook-shaped groove 14 of the aluminum block is as shown in FIG. Figure 7 As shown, the oval groove of the aluminum block is Figure 3 shown.

[0111] The fixed magnetization effect produced by this magnetic assembly is the same as that of the embodiment 3, except that the hook made of magnet, pure iron, silicon steel or Permalloy is encapsulated in the aluminum block to form an assembly, which is convenient for assembly and practical.

[0112] When the two hooks are placed tangentially, placing the substrate printed with magnetic ink on top of them will also produce an S-shaped effect, but the S-shaped effect is more outward, and the greater the distance between the tangent and non-contact, the more outward. The inward buckling method has a good dynamic effect and a more beautiful expression.
