Description

Technical Field

[0001] The invention relates to the technical field of cosmetics, and in particular to one-time formed false eyelashes and a preparation and wearing method thereof. Background Art

[0002] False eyelashes are a cosmetic product that improves the beauty of the eyes by sticking false eyelashes on natural eyelashes. Segmented self-grafted eyelashes are a type of false eyelashes that can be used repeatedly and do not need to be installed and uninstalled every day. Compared with traditional eyelashes, they are more economical and environmentally friendly, and are increasingly widely used.

[0003] However, the current segmented self-grafted false eyelashes have many shortcomings: 1. Most of the existing false eyelashes are made of finished eyelash filaments through processes such as bonding, gluing, cutting, and heating and shaping, which are complex, inefficient, high in production cost, and long in preparation process; 2. Whether the existing false eyelashes are fixed in a linear, film-shaped, or glue-coated stem shape, the eyelash filaments and the eyelash stems are physically connected, the product life is short, and the wearing comfort is poor; 3. At present, the eyelash filaments are usually bent and formed by heating and bending, which is prone to cause safety problems such as burns, and has low molding efficiency. At the same time, heating is likely to affect the physical and chemical properties of the material, such as strength, hardness, etc., thereby affecting the quality of the finished product, resulting in the existing false eyelashes. When worn, the requirements for the glue used for grafting and the glue application method are high, and wearing is relatively time-consuming and labor-intensive. Summary of the invention

DETAILED DESCRIPTION

[0038] In order to make the present invention clearer and more understandable, the technical solution of the present invention is further described in detail below in combination with the accompanying drawings and embodiments. It should be understood that the given embodiment is only one of the implementation methods and does not represent all embodiments.

[0039] In this article, the terms "upper, lower, inside, outside" and the like are established based on the positional relationships shown in the drawings. Depending on the different drawings, the corresponding positional relationships may also change accordingly. Therefore, they cannot be understood as absolute limitations on the scope of protection.

[0040] Combined with Figure 1 -Attached Fig.10 , a method for preparing one-time formed false eyelashes, comprising the following steps:

[0041] S1. Select a sheet-like film material as the base material, the base material is made of plastic or polyester material, and use a laser cutting device to cut the base material into filaments according to preset parameters to form a single eyelash or an integrally formed semi-finished eyelash;

[0042] Specifically, step S1 is:

[0043] S11. Prepare materials

[0044] (1) Ensure that the substrate is flat and wrinkle-free, and the thickness meets the design requirements;

[0045] (2) Clean the surface of the substrate to remove dust and other contaminants.

[0046] S12. Design drawings

[0047] (1) Use CAD software to create the design drawings of the required single eyelashes or semi-finished eyelashes;

[0048] (2) Adjust the size, shape and other parameters in the drawing according to actual needs.

[0049] S13. Import drawings

[0050] Import the designed drawings into the control software equipped with the laser cutting machine.

[0051] S14. Adjust equipment parameters

[0052] Set the laser power, speed, and frequency, which are determined by the substrate thickness and the required cutting quality;

[0053] To ensure accurate parameter adjustment and avoid wasting materials, you can first test the cutting effect on waste materials to adjust the parameters to the best state; the power is generally set to 1-100 watts and the cutting speed is 1-8000mm per second.

[0054] S15, Fixing materials

[0055] Secure the substrate to the table using a clamp or vacuum to ensure it does not move during the cutting process.

[0056] S16, start cutting

[0057] After checking the equipment settings, start the laser cutting machine and start cutting.

[0058] S17. Monitoring process

[0059] Monitor the working status of the equipment during the cutting process. If there is any abnormality, stop the operation immediately and check the cause.

[0060] S18. After completion processing

[0061] After cutting, remove the cut membrane and check whether there are burrs or incomplete cuts;

[0062] If there are burrs or incomplete cuts, subsequent processing such as edge grinding or secondary cutting can be performed.

[0063] Different types of laser cutting machines can be selected for diaphragm laser cutting. The selectable laser cutting machines include but are not limited to CO2 lasers, UV lasers, picosecond lasers, and femtosecond lasers.

[0064] S2. If the eyelashes are cut into single pieces, two single eyelashes are combined and fixed as needed to obtain semi-finished eyelashes of different styles;

[0065] Specifically, the single eyelash includes an integrally formed single eyelash root connecting stem 32 and a plurality of single eyelash filaments 31, wherein the single eyelash filaments 31 are located on one side of the single eyelash root connecting stem 32, and the single eyelash root connecting stem 32 is in a straight strip shape, an arc shape, or a wavy shape.

[0066] More specifically, the angle between the single eyelash filament 31 and the single eyelash root connecting stem 32 is 1-90°, that is, the single eyelash filament 31 can be perpendicular to the single eyelash root connecting stem 32 or inclined to the single eyelash root connecting stem 32, and the angle is preferably 30-90°. Multiple single eyelash filaments 31 can be arranged one by one along the single eyelash root connecting stem 32, or can be arranged in clusters along the single eyelash root connecting stem 32, with at least 2 single eyelash filaments 31 forming a cluster. The arrangement shape of the multiple single eyelash filaments 31 on each single eyelash root connecting stem 32 can be set according to demand, that is, by setting the inclination angle and length of each single eyelash filament 31, the single eyelash filament 31 can be arranged in different shapes, such as a fan shape or a right-angled trapezoid.

[0067] Specifically, at least two single-piece grafting columns 33 are provided on a side of the single-piece eyelash root connecting stem 32 away from the single-piece eyelash filament 31 , and the single-piece grafting columns 33 are integrally formed with the single-piece eyelash root connecting stem 32 .

[0068] Specifically, two single eyelashes are bonded together by glue or tape to achieve combined fixation. The two single eyelashes combined can be both with single grafting posts 33, both without single grafting posts 33, or one with single grafting posts 33 and the other without single grafting posts 33. When the two single eyelashes combined are one with single grafting posts 33 and the other without single grafting posts 33, the formed eyelashes are semi-finished eyelashes with grafting posts 36.

[0069] Compared with the semi-finished eyelashes formed by laser cutting directly in one piece, the semi-finished eyelashes formed by combining two single eyelashes have the same overall structure. However, compared with the semi-finished eyelashes formed in one piece, when the two single eyelashes are combined, the single eyelash filaments 31 of the two single eyelashes are not in the same plane, and the single eyelash filaments 31 of the two single eyelashes may not be bonded to each other, so the semi-finished eyelashes formed have a stronger three-dimensional sense and a better visual effect.

[0070] It is important to understand that Figure 8 -Attached Fig.10 Several schematic diagrams of the structures of single eyelashes and semi-finished eyelashes are given. The eyelash structures given are only examples and do not represent all shapes of eyelashes.

[0071] S3, placing the semi-finished eyelashes in a pressure plastic shaping device, the pressure plastic shaping device applies pressure to the semi-finished eyelashes 34, so that the semi-finished eyelashes 34 are bent and shaped to obtain finished false eyelashes.

[0072] Specifically, the pressure plastic shaping device applies pressure to the semi-finished eyelash filaments 34 in the following ways: rolling shaping and stamping shaping.

[0073] Specifically, the pressure plastic forming device includes a stamping forming device, which includes a frame 3, a controller 2, a cylinder control valve 6, an air source, a stamping cylinder 4, an air source processor 7 and a carrier 8. The stamping cylinder 4 is fixed on the frame 3, and a forming plate 5 is fixed at the telescopic end of the stamping cylinder 4. The carrier 8 is located on one side of the telescopic end of the stamping cylinder 4. The carrier 8 is fixed relative to the frame 3. A forming groove 9 corresponding to the position of the forming plate 5 is provided on the carrier 8. The stamping cylinder 4 is connected to the cylinder control valve 6 through an air pipe, and the cylinder control valve 6 is connected to the output end of the air source processor 7 through an air pipe. The input end of the air source processor 7 is connected to the air source through an air pipe, and the controller 2 is electrically connected to the cylinder control valve 6 and the air source processor 7 respectively.

[0074] Specifically, the step S3 is as follows: placing the semi-finished eyelashes on the loading part 8, so that the semi-finished eyelashes 34 are located on the shaping groove 9, starting the stamping cylinder 4, the telescopic end of the stamping cylinder 4 drives the shaping plate 5 to move in the direction of the shaping groove 9, and the shaping plate 5 presses the semi-finished eyelashes 34 into the shaping groove 9. After each pressing of the shaping plate 5, the telescopic end of the stamping cylinder 4 drives the shaping plate 5 to retract, and moves the semi-finished eyelashes 34 along the length direction of the eyelashes once, so that the unpressed part of the semi-finished eyelashes 34 is located on the shaping groove 9, and the stamping cylinder 4 drives the shaping plate 5 to press down again, and presses the unpressed part of the semi-finished eyelashes 34 into the shaping groove 9, and so on. The cycle is repeated to realize the segmented cold stamping of the semi-finished eyelashes 34, so that the semi-finished eyelashes 34 are bent and shaped. More specifically, when cold stamping the semi-finished eyelashes, the end of the semi-finished eyelashes 34 away from the semi-finished eyelash stem 35 is first placed on the shaping groove 9.

[0075] Specifically, a shaping end 10 is fixed to one end of the shaping plate 5 close to the object-carrying part 8, and the shaping end 10 is serrated at one end close to the object-carrying part 8. The serrated setting can achieve point pressing on the eyelashes, and the bending and forming effect is better. The object-carrying part 8 and the frame 3 are fixed on the second base 1.

[0076] Specifically, two slide rails 11 are provided on the top surface of the loading part 8, and the two slide rails 11 are respectively located at the two ends of the shaping groove 9, and the length direction of the slide rails 11 is consistent with the moving direction of the semi-finished eyelash filament 34. The slide rails 11 are slidably provided with a sliding block 12, and the two sliding blocks 12 are fixedly connected with a mounting plate 14, and the mounting plate 14 is hinged with a fixing plate 13 at one end close to the shaping groove 9. When punching, the fixing plate 13 can be rotated so that the side of the fixing plate 13 close to the loading part 8 is away from the loading part 8, and the semi-finished eyelashes can be detachably fixed on the side of the fixing plate 13 close to the loading part 8, and the semi-finished eyelashes filament 34 is located outside the fixing plate 13. After the semi-finished eyelashes are fixed, the fixing plate 13 is rotated so that the fixing plate 13 is pressed on the loading part 8, and the semi-finished eyelashes are located between the fixing plate 13 and the loading part 8; when the semi-finished eyelashes need to be moved, the staff pushes the fixing plate 13 or the mounting plate 14 so that the fixing plate 13 slides along the slide rail 11, and the semi-finished eyelashes are moved through the fixing plate 13. When the staff directly holds the semi-finished eyelashes for stamping, it is difficult to ensure the stability of the movement of the semi-finished eyelashes manually, and the moving path is prone to be skewed, which affects the effect after shaping, and the staff's hands are prone to touch the stamping cylinder 4, which is low in safety. Using the fixing plate 13 to move the semi-finished eyelashes can ensure the stability of the movement and improve the safety of the stamping operation. More specifically, the semi-finished eyelashes and the fixing plate 13 can be bonded by tape.

[0077] Specifically, the pressure plastic shaping device includes a rolling shaping device, which includes a roller 18 and a covering structure. The outer wall of the roller 18 is provided with a plurality of pointed protrusions, and the plurality of pointed protrusions cover the outer wall of the roller 18. The pointed protrusions can realize point pressure on the semi-finished eyelashes. The semi-finished eyelashes are roll-formed by using the rolling shaping device. The rolling forming method is: the semi-finished eyelashes are wrapped on the outer wall of the roller 18 by using the covering structure, so that the semi-finished eyelashes are bent along the circumference of the roller 18, and the length of the semi-finished eyelash filaments 34 is not greater than the circumference of the roller 18. After the wrapping is completed, the roller 18 wrapped with the semi-finished eyelashes and the covering structure is rolled on the work surface, and the roller 18 is pressed down while rolling.

[0078] Specifically, the rolling shaping device further includes a first base 23, a bracket 15 and a first cylinder 16, wherein the bracket 15 is fixed on the first base 23, the first cylinder 16 is fixed on the bracket 15, the telescopic end of the first cylinder 16 extends downward and is fixed with a roller mounting frame 17, the two ends of the roller 18 are rotatably connected to the roller mounting frame 17 through a rotating shaft 30, and a distance is maintained between the end of the roller 18 and the roller mounting frame 17;

[0079] A guide rod 24 is fixed on the top of the roller mounting frame 17 , and the guide rod 24 is slidably connected to the bracket 15 , so that the stability of the movement of the roller mounting frame 17 is improved by the guide rod 24 .

[0080] The covering structure includes a semi-cylindrical shell 19, the inner diameter of the semi-cylindrical shell 19 is not less than the diameter of the roller 18, the length of the semi-cylindrical shell 19 is not less than the length of the roller 18, a baffle 193 is fixed at each end of the semi-cylindrical shell 19, a placement groove 25 with a semicircular bottom end is opened on the upper part of the baffle 193, the radial dimension of the placement groove 25 is the same as the diameter of the rotating shaft 30, and an arc-shaped slider 28 is fixed on the side of the baffle 193 away from the semi-cylindrical shell 19;

[0081] An elastic telescopic rod 20 is fixed to each of the two ends of the semi-cylindrical shell 19 on the first base 23, a semi-circular slide rail 26 is fixed to the top of the elastic telescopic rod 20, the arc-shaped slider 28 is slidably arranged in the semi-circular slide rail 26, the inner diameter of the semi-circular slide rail 26 is larger than the diameter of the rotating shaft 30, and baffles 27 are fixed to the two ends of the top of the semi-circular slide rail 26, and the baffles 27 are used to limit the arc-shaped slider 28 to prevent the arc-shaped slider 28 from detaching from the semi-circular slide rail 26;

[0082] The inner diameter of the arc-shaped slider 28 is the same as the diameter of the rotating shaft 30, and the outer diameter of the arc-shaped slider 28 is the same as the inner diameter of the semicircular slide rail 26; the arc-shaped slider 28, the semicircular slide rail 26, the semi-cylindrical shell 19 and the semicircular end of the placement groove 25 are coaxially arranged, the axis of the semi-cylindrical shell 19 and the axis of the roller 18 are located in the same vertical plane, and the semi-cylindrical shell 19 is located below the roller 18;

[0083] A slide plate 21 is slidably disposed on the first base 23 . The slide plate 21 is located below the semi-cylindrical shell 19 . The slide plate 21 is driven by a second cylinder 22 . The top surface of the slide plate 21 is the work surface.

[0084] The step S3 is specifically as follows: placing the semi-finished eyelashes in the semi-cylindrical shell 19, starting the first cylinder 16, and the first cylinder 16 drives the roller 18 to move downward, so that the lower part of the roller 18 enters the semi-cylindrical shell 19, and at the same time, the rotating shaft 30 enters the placement groove 25 and the semi-circular slide rail 26. After the roller 18 is coaxial with the semi-cylindrical shell 19, the semi-finished eyelashes are wrapped around the outer wall of the roller 18 under the extrusion of the roller 18 and the semi-cylindrical shell 19; the first cylinder 16 continues to drive the roller 18 to move downward, and at this time, the roller 18 drives the semi-cylindrical shell 19 to move downward. The shell 19 moves downward, and the elastic telescopic rod 20 is compressed. After the semi-cylindrical shell 19 contacts the top surface of the slide plate 21 and applies pressure to the slide plate 21 (that is, after the semi-cylindrical shell 19 contacts the top surface of the slide plate 21, the telescopic end of the first cylinder 16 still extends a certain distance), the first cylinder 16 stops moving, and the second cylinder 22 starts. The second cylinder 22 repeatedly extends and retracts to drive the slide plate 21 to slide back and forth, and the slide plate 21 drives the semi-cylindrical shell 19 and the roller 18 to rotate back and forth, thereby rolling the semi-finished eyelashes and bending and shaping the semi-finished eyelashes.

[0085] Specifically, the bottom of the semi-cylindrical shell 19 is made of heavy material 192, such as iron and lead, and the two sides of the semi-cylindrical shell 19 are made of light material 191, such as aluminum alloy. By arranging the heavy material 192 at the bottom of the semi-cylindrical shell 19, it can be ensured that when the semi-cylindrical shell 19 is not working, it can maintain a stable position under the action of gravity, and ensure that the roller 18 can accurately fall into the semi-cylindrical shell 19 when it moves downward.

[0086] More specifically, to ensure that the semi-cylindrical shell 19 can better follow the movement of the roller 18, a protrusion can be set on the top of the arc-shaped slider 28, and a groove can be set on the rotating shaft 30 at a position corresponding to the protrusion. After the roller 18 moves downward, the protrusion is inserted into the groove.

[0087] Specifically, a flexible material layer 29, such as a rubber layer, is disposed inside the semi-cylindrical shell 19 to provide a certain degree of protection for the semi-finished eyelashes.

[0088] Specifically, the top surface of the skateboard 21 and the outer wall of the semi-cylindrical shell 19 can be set to a rough surface, such as setting a plurality of protrusions on the top surface of the skateboard 21 and the outer wall of the semi-cylindrical shell 19 to increase the friction between the top surface of the skateboard 21 and the outer wall of the semi-cylindrical shell 19, so that the skateboard 21 can better drive the semi-cylindrical shell 19 to rotate.

[0089] Disclosed is a disposable false eyelash, comprising an integrally formed eyelash filament, an eyelash stem and a grafting column, wherein the eyelash filaments are multiple and located on one side of the eyelash stem, and the grafting column is located on the other side of the eyelash stem, and there are at least two grafting columns.

[0090] A method for wearing one-time formed false eyelashes. When wearing, glue for eyelash grafting is applied on a grafting column and / or an eyelash stem, and then the grafting column and / or the eyelash stem are bonded to real eyelashes, and the false eyelashes are located above or below the real eyelashes.

[0091] When a grafting column is provided, glue can be applied only on the grafting column, and the grafting column can be more accurately bonded to the root of the real eyelashes. When glue is only applied on the grafting column, the amount of glue applied is small, which can greatly reduce the irritation to the wearer's eyes. At the same time, the bonding time is longer, which increases the wearing time, and the wearer does not need to frequently change false eyelashes.

[0092] While embodiments of the present invention have been shown and described, it will be apparent to those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
