Description
Technical Field
[0001] This utility model relates to the field of nail product processing technology, and more specifically to a magnetic shaping device for cat-eye false nail tips. Background Technology
[0002] Patent application number 202321771848.5 discloses a magnetic attraction and fixation device for a cat-eye effect on wearable nail plates. The device includes an upper cover, an upper magnetic mold, a lower magnetic mold, and a pre-curing lamp. The lower magnetic mold is positioned below and corresponding to the upper magnetic mold, forming a receiving cavity between them. The upper magnetic mold is mounted on the upper cover, and the pre-curing lamp is detachably connected to the upper cover. By mounting the upper magnetic mold on the upper cover, the upper and lower magnetic molds can be easily engaged and disengaged, making operation convenient. The upper and lower magnetic molds work together on the nail plate on the nail plate mounting plate to achieve the cat-eye effect. The pre-curing lamp allows for curing the magnetic coating after molding, achieving a fixed magnetic effect.
[0003] Existing cat-eye nail art techniques mostly present static textures, lacking dynamic changes and having a weak visual impact. Furthermore, traditional molding processes can only create cat-eye effects on a single nail piece at a time, making it impossible to process the same batch of nail pieces in bulk. This results in low production efficiency, poor process flexibility, and difficulty in meeting diverse nail art needs. Utility Model Content
[0004] The purpose of this utility model is to overcome the above-mentioned defects of the existing technology and provide a magnetic shaping device for cat-eye false nail pieces. It can flexibly achieve dynamic cat-eye effects for any single, multiple, or all false nail pieces on the same nail blank in batches. It also lays the technical groundwork for the integration of other static cat-eye effects, and realizes the smooth completion of multiple cat-eye effects in the same process. This makes the process both standardized and flexible, taking into account both mass production efficiency and personalized customization, and meeting the diverse processing needs of nail products.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a magnetic suction shaping device for cat-eye false nail tips, comprising a magnetic suction module and a curing lamp assembly, characterized in that the magnetic suction module comprises a pair of magnetic upper molds and magnetic lower molds forming a split composite structure and made of non-magnetic materials; a storage cavity is provided at the transverse center of the magnetic lower mold; a nail tip blank holder is inserted into the storage cavity; the nail tip blank holder has multiple nail tip holders arranged in a display arrangement; each nail tip holder has a storage groove on its side; each storage groove is arranged perpendicular to the storage cavity, but they are not interconnected. Each of the aforementioned storage slots contains a free-state strong magnetic column. The horizontal center of the magnetic suction upper mold is provided with multiple light-transmitting holes arranged in a row. Each light-transmitting hole corresponds to one of the aforementioned axle holders. Each light-transmitting hole is provided with a needle-passing groove that is not connected to it. A magnetic guide rod is installed on the isolation strip between each pair of needle-passing grooves and light-transmitting holes through a detachable mechanism. One end of each magnetic guide rod is provided with a magnetic suction head that extends horizontally into the corresponding light-transmitting hole. The other end of each magnetic guide rod is provided with a magnetic guide foot that extends vertically through the corresponding needle-passing groove.
[0006] This invention aims to flexibly and in batches achieve dynamic heart-shaped cat-eye effects on any single, multiple, or all artificial nail pieces on the same nail blank, and lays the technical groundwork for incorporating other static cat-eye effects. It achieves the seamless completion of multiple cat-eye effects within the same process, implemented in three layers: First, the magnetic field arrangement of the magnetic modules next to the nail holders is independent, without interference, and can be easily disassembled and installed as needed; second, during the light-curing process of the heart-shaped cat-eye effect nail coating, other nail coatings that do not require a cat-eye effect must not be cured by light, so each light-transmitting hole exists independently, and a light-shielding cover is added to selectively block UV rays; finally, before baking and curing, other cat-eye effects are incorporated and interspersed.
[0007] The strong magnetic column generates a magnetic field that magnetizes the surrounding magnetic materials. Even without contact with the magnetic guide foot, as long as it is close, it can be magnetized and magnetically attracted. In this invention, the magnetic guide foot is preferably connected to one of the two end faces of the strong magnetic column. The contact part is the radius length. The copper sheet, plastic wheel and isolation strip all serve to isolate the magnetic field.
[0008] Preferably, the detachable mechanism includes a groove disposed on the isolation strip, the two ends of the groove being connected to the needle groove and the light-transmitting hole respectively, a screw hole being disposed on the side of the groove, a top pressure plate made of non-magnetic material covering the groove, a top pressure wheel also made of non-magnetic material being pressed onto the top pressure plate, and the top pressure wheel being fixed by a bolt fitted in the screw hole.
[0009] This invention provides an independent magnetic field for each nail plate base that does not interfere with each other, and it can be flexibly selected and installed in batches to achieve the heart-shaped cat-eye effect for any single, multiple, or all artificial nail plates on the same nail plate blank.
[0010] Preferably, the top pressure plate is a copper sheet, and the top pressure wheel is a plastic wheel.
[0011] Preferably, the magnetic suction head is V-shaped.
[0012] This utility model achieves a dynamic heart-shaped cat-eye effect through precise magnetic powder arrangement and magnetic field control. The heart pattern presents a dynamic sense of light and shadow flow as the viewing angle changes, gradually enlarging and shrinking, with a strong dynamic visual impact. It can easily create a rich and three-dimensional aesthetic, far exceeding the static decorative effect of ordinary nail art.
[0013] The principle behind the dynamic visual effect of the heart-shaped cat-eye effect in this invention is as follows: When the nail coating is treated with a V-shaped magnetic grinding head, a heart-shaped cat-eye effect appears. This effect is mainly related to the shape of the magnetic grinding head and the way the magnetic field works. The magnetic part of the V-shaped grinding head forms two magnetic field regions at an angle. When these two magnetic fields act on the cat-eye glue containing magnetic powder, the magnetic powder aligns along the direction of the magnetic field. Then, the angle of the V-shape becomes the convergence point of the magnetic field, causing the magnetic powder to follow a symmetrical arc in the center and on both sides of the angle. Finally, they overlap to form a heart-like outline. The magnetic field on both sides guides the magnetic powder to form two arcs of the heart, while the apex of the angle corresponds to the tip of the heart, thus presenting a heart-shaped cat-eye effect.
[0014] The dynamic heart-shaped cat-eye effect appears to "shrink" or "expand" when the fake nail moves. The core reason is that changes in the viewing angle alter the visual field of the magnetic powder arrangement guided by the magnetic field, changing the angle between your line of sight and the reflective band of the magnetic powder. When the angle is directly facing you, you can see the entire heart outline formed by the magnetic powder arrangement, making it appear "larger." When the angle is tilted (upward or downward after facing directly), the visible range of the reflective band is compressed, and the edges become blurred due to reduced reflection, making the heart outline appear "shrink" or even disappear in parts. Simply put, it's like looking at a flashlight beam: the beam is largest when facing directly, and smaller and narrower when tilted. Essentially, the visible range of light (in this case, the magnetic powder reflection) changes with the angle.
[0015] Preferably, the magnetic upper mold and the magnetic lower mold are connected by a pair of spaced-apart hinges.
[0016] This utility model's magnetic suction module connects the upper and lower molds via hinges, ensuring precise alignment when the upper and lower molds are fitted together, while also allowing for flexible opening and closing. This facilitates the placement and removal of nail pieces and adjustment of the magnetic suction angle, improving the efficiency and stability of creating the cat-eye effect.
[0017] Preferably, a handle is provided on the outer end face of the magnetic upper mold.
[0018] This invention adds a handle to the magnetic upper film, which can easily control the opening and closing of the upper film, avoids hand contact with the mold affecting the magnetic suction accuracy, and improves the convenience of operation and the stability of the effect.
[0019] Preferably, the curing lamp assembly includes a gantry-shaped lampshade, and several UV light strips are pasted on the inner bottom surface of the lampshade, the number of which is the same as the number of rows of light-transmitting holes, with each UV light strip corresponding to one row of light-transmitting holes.
[0020] The UV light strips inside the gantry-type lampshade of this utility model are arranged in an array corresponding to the light-transmitting holes. This ensures that each light-transmitting area receives uniform and sufficient ultraviolet light, and also accurately focuses on the curing position, thereby improving the efficiency and consistency of UV varnish curing.
[0021] Preferably, the magnetic module also includes a number of light-shielding covers equal to the number of light-transmitting holes, and each light-shielding cover has a step at its lower end that is interference-fitted with the corresponding light-transmitting hole.
[0022] This invention adds a light-shielding cover to the light-transmitting hole to prevent all the painted nail pieces on the same nail plate blank from being light-cured, leaving some uncured pieces to lay the technical groundwork for subsequent measures to incorporate other cat-eye effects.
[0023] Beneficial effects: This utility model can flexibly achieve dynamic cat-eye effects on any single, multiple, or all artificial nail pieces on the same nail blank, and lays the technical foundation for the integration of other static cat-eye effects. It enables the sequential completion of multiple cat-eye effects within the same process, making the process both standardized and flexible, taking into account both mass production efficiency and personalized customization, and meeting the diverse processing needs of nail products.

Detailed Implementation
[0026] To make the technical means, creative features and objectives of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments.
[0027] Example: Figure 1 As shown, a magnetic shaping device for cat-eye false nail tips includes a magnetic module 1 and a curing lamp assembly.
[0028] like Figure 2 and Figure 3 As shown, the magnetic module 1 includes a pair of magnetic upper mold 4 and magnetic lower mold 5, which form a split composite structure and are made of non-magnetic material (aluminum). The magnetic upper mold 4 and magnetic lower mold 5 are connected by a pair of spaced-apart hinges 6. A handle 7 is provided on the outer end face of the magnetic upper mold 4.
[0029] like Figure 4 , Figure 5 and Figure 6 As shown, a storage cavity 8 penetrating the thickness of the lower mold is provided in the transverse center of the magnetic lower mold 5. A plate blank holder 9 that matches the shape of the plate blank coming out of the injection molding machine is inserted into the storage cavity 8. The plate blank holder 9 has two rows of plate blank holders 10 arranged at equal intervals (ten in each row, for a total of twenty). Each plate blank holder 10 has a storage groove 11 on its side. Each storage groove 11 is arranged perpendicular to the storage cavity 10, but they are not interconnected. A free-state strong magnetic column 12 is placed in each storage groove 11. The strong magnetic column 12 can also be fixed in the corresponding storage groove 11 by glue or other auxiliary materials.
[0030] The upper magnetic mold 4 has two rows of equally spaced light-transmitting holes 13 (ten in each row, for a total of twenty) arranged at its horizontal center. Each light-transmitting hole 13 corresponds to a plate holder 10 when the upper magnetic mold 4 and the lower magnetic mold 5 are closed. Each light-transmitting hole 13 has a needle groove 14 that is not connected to it. A magnetic rod 16 is installed on the isolation strip 15 between each pair of needle grooves 14 and light-transmitting holes 13 through a detachable mechanism. One end of each magnetic rod 16 has a magnetic mold head 17 that extends horizontally into the corresponding light-transmitting hole. The magnetic mold head 17 is V-shaped. The other end of each magnetic rod 17 has a magnetic foot 18 that extends vertically through the corresponding needle groove 14 and into the corresponding storage groove 11 when the upper magnetic mold 4 and the lower magnetic mold 5 are closed.
[0031] The detachable mechanism includes a groove 19 set on the isolation strip. The two ends of the groove 19 are respectively connected to the needle groove 14 and the light-transmitting hole 13. A screw hole 20 is provided on the side of the groove 19. A top pressure plate 21 made of non-magnetic material is covered on the groove 19. The top pressure plate 21 is a copper sheet. A top pressure wheel 22 made of non-magnetic material is pressed on the top pressure plate 21. The top pressure wheel 22 is a plastic wheel. The top pressure wheel 22 is fixed by a bolt 23 that fits in the screw hole 20.
[0032] The curing lamp assembly includes a gantry-shaped lamp cover 2. Two UV light strips 3, the same number as the number of rows of light-transmitting holes, are pasted on the inner bottom surface of the lamp cover 2. Each UV light strip 3 corresponds to a row of light-transmitting holes 13 when the magnetic upper mold 4 and magnetic lower mold 5 are closed.
[0033] The magnetic module 1 also includes twenty light-shielding covers 24, the same number as the light-transmitting holes. The light-shielding covers 24 are also made of non-magnetic materials, preferably thick plastic (such as PVC or ABS). Each light-shielding cover 24 has a step at its lower end that is interference-fitted with the corresponding light-transmitting hole 13.
[0034] A process for creating false nail tips with a dynamic heart-shaped cat-eye effect includes the following steps: (1) Prepare magnetic suction module and curing lamp assembly. The magnetic suction module includes magnetic upper mold and magnetic lower mold, and the curing lamp assembly includes UV lamp strip; (2) Magnetic field preparation: According to different customer needs, the heart-shaped cat-eye effect of any single or multiple or all fake nail pieces on the same nail blank can be flexibly achieved in batches. The magnetic field is arranged next to the nail holder that supports the fake nail piece that needs to achieve the heart-shaped cat-eye effect. (3) Place a strong magnetic column in the storage slot next to the plate holder where a magnetic field needs to be arranged, and then place a magnetic rod near the corresponding light-transmitting hole. The magnetic rod is fixed in the corresponding groove between the needle groove and the light-transmitting hole by pressing the copper plate with a plastic wheel. The V-shaped magnetic suction head at the front end of the magnetic rod is presented in the corresponding light-transmitting hole. The magnetic foot at the rear end of the magnetic rod extends through to the outside of the corresponding needle groove. When the upper magnetic suction mold and the lower magnetic suction mold are closed, the magnetic foot contacts the corresponding strong magnetic column, thereby conducting and finally magnetizing the magnetic suction head together. (4) In the storage slot, light-transmitting hole and needle-passing slot next to the plate holder where no magnetic field is required, the above-mentioned strong magnetic column and magnetic rod are not installed, and the light-blocking cover is directly placed in the corresponding light-transmitting hole. (5) Add the cat's eye powder containing magnetic powder to the plastic paint and stir it thoroughly with a mixer at low speed to ensure that the cat's eye powder is evenly dispersed; (6) Take a plate blank and place it in the spray booth. Use the spray gun to sweep and spray it back and forth evenly 1-2 times. Keep the distance between the spray gun and the plate blank 15-25cm during the sweeping and spraying. (7) Magnetic field positioning: Before the coating dries, place the painted nail blank into the nail blank holder of the magnetic lower mold. Each fake nail corresponds to one nail holder. Ensure that each fake nail that needs to achieve the heart-shaped cat-eye effect is placed on the nail holder that has been arranged with the magnetic field. Then, the magnetic upper mold and the magnetic lower mold are closed. The magnetic mold head that is conducted and magnetized approaches the coating surface of the corresponding fake nail. The cat-eye powder in the latter coating is arranged along the direction of the magnetic field. Since the surface of the fake nail is arc-shaped, a hazy large V is formed at the near end of the magnetic field and a hazy small V is formed at the far end of the magnetic field. When the large V and small V meet, a heart-shaped cat-eye effect is formed. (8) Photocuring: The curing lamp is placed on the magnetic module. The ultraviolet light emitted by the UV lamp strip acts on the coating with the completed heart-shaped cat-eye effect through the light-transmitting hole, and then performs a photocuring reaction; while the coating that does not need the heart-shaped cat-eye effect is blocked by the light-shielding cover and is not photocured. (9) Finally, remove the curing lamp assembly, open the magnetic upper mold and magnetic lower mold to take out the semi-finished false nail piece with heart-shaped cat-eye nail art effect, transfer it for medium and low temperature baking and curing, and obtain the finished false nail piece with heart-shaped cat-eye nail art effect.
[0035] In step (5) above, the magnetic powder content in the cat's eye powder is preferably in the range of 12%-15%, and the proportion of cat's eye powder in the plastic paint is preferably in the range of 0.3%-30%, and the plastic paint is a UV varnish.
[0036] If you want a more pronounced cat-eye effect, the proportion of cat-eye powder can be higher, ideally between 10% and 30%. If you want the varnish to maintain good fluidity and transparency, and also consider curing effect and adhesion, then keep it between 0.3% and 10%.
[0037] In step (6) above, the nozzle diameter of the spray gun is preferably 1.5-2.0 mm.
[0038] In step (7) above, the magnetic attraction time of the heart-shaped cat-eye effect coating is preferably controlled within 3-10 seconds.
[0039] In step (8) above, the time of photocuring reaction is preferably controlled within 30-60 seconds.
[0040] In step (9) above, the baking temperature for medium-low temperature baking and curing is controlled at 60-80 degrees Celsius.
[0041] In step (9) above, other cat-eye effects can be created by mixing the uncured false nail coating. Magnetic suction heads of different shapes are used to magnetically attract the cat-eye powder. The magnetic particles in the cat-eye powder will be attracted and gathered under the action of the magnetic field, arranged in an orderly manner into a specific shape, and then baked together with the semi-finished heart-shaped cat-eye nail art effect false nail to medium and low temperature to obtain the finished product.
