TECHNICAL FIELD

[0001] The present application relates to the field of make-up technology, in particular to a curling process for false eyelashes. BACKGROUND

[0002] Artificial eyelashes for beautifying eyes are generally made by lengthening and thickening the eyelashes to make the eyes look bigger, brighter, fuller and more spiritual. Most of the false eyelashes currently sold on the market are produced by the processes of clamping, aligning, cutting, curling, shaping and mounting. The current curling operation is as follows: the curling paper is laid flat on the workbench, then the curling paper is wetted by using a brush to dip water and brush the entire curling paper, then the hair material is pasted on the curling paper row by row, after the curling paper is fully pasted, a plastic curling tube is placed on the curling paper, and the curling paper is wound around the curling tube to complete the curling. At this time, the hair material is wound on the curling tube, and the curling tube is then dried and disassembled. At this time, the hair material will be in a curved shape.

[0003] The existing curling step is manually operated. The manual curling speed is slow, time-consuming and labor-intensive, and the curling quality is uneven, which cannot meet the curling needs of false eyelashes of different grades, resulting in a high loss rate and low economic benefits. SUMMARY

[0004] The present application aims to provide a curling process for false eyelashes to solve at least one of the problems raised in the background.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solution: a curling process for false eyelashes, the steps are as follows: 1: preparation of false eyelash semi-finished product and curling paper; S1: preparation of false eyelash semi-finished product, curling tube and curling paper; S2: false eyelash semi-finished product fixing and curling paper winding; S3: curling tube and curling paper winding material clamping; S4: curling paper winding and curling tube synchronous conveying; S5: curling paper tension control; S6: curling paper wrapping curling tube forming; S7: fixed length cutting; S8: finished product detection and sorting; S9: infrared lamp tube shaping S10: equipment cleaning and maintenance; S11: quality detection and process optimization of false eyelash shaping.

[0006] Preferably, in step S1, three rows of false eyelash semi-finished products are arranged on the curling paper.

[0007] Preferably, in step S1, the curling paper is made of wood pulp paper, and the curling tube is made of food-grade PET.

[0008] Preferably, in step S2, after the false eyelash semi-finished product is screened, the eyelash silk is combed by a special brush to ensure consistent direction and prevent the eyelash silk from knotting.

[0009] Preferably, in step S2, the false eyelash semi-finished product is pasted on the rolled tube paper by a high-temperature adhesive tape.

[0010] In step S9, the false eyelash shaping is performed by high-temperature shaping with an infrared lamp tube.

[0011] Preferably, in step S11, the quality detection is performed in the form of sampling inspection.

[0012] The beneficial effects of the present application are as follows: 1. In the present application, the process breaks through the limitations of traditional manual rolling of the tube, and the rolled tube paper and the rolled tube are synchronously conveyed by the cooperation of the vibrating disc automatic conveying rolled tube, the conveying chain, and the photoelectric sensor and PLC control system to realize material shortage detection and automatic deviation correction. Manual rolling and manual lashing of the material are not required, the labor input is greatly reduced, the rolling speed is significantly improved, false eyelashes of different shapes, thicknesses and thicknesses can be made, the time and labor consumption problem of manual rolling is effectively solved, and the scale production demand is met.

[0013] 2. In the present application, the infrared lamp tube is used for heating in the false eyelash shaping link, which has the following advantages compared with the traditional steam box heating: no need to preheat the whole box of steam like the steam box, the infrared lamp tube has a fast heating speed and can directly act on the false eyelash for heating and shaping, which greatly improves the shaping efficiency; only the target area of the false eyelash is heated, there is no waste of excess heat, and the energy consumption cost can be reduced in long-term use; at the same time, the humidity influence caused by steam is avoided, the false eyelash has uniform curl after shaping and is not easy to soften, the shaping effect is more durable and stable, and the curl consistency and quality reliability of false eyelashes of different grades are further guaranteed.

BRIEF DESCRIPTION OF DRAWINGS

[0015] Figure 1 The present application is a rolled tube, a false eyelash semi-finished product and a rolled tube paper position diagram; DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0017] The present application provides a false eyelash winding process as shown in the following steps: Figure 1 S1: false eyelash semi-finished product, winding and winding paper preparation; S2: false eyelash semi-finished product fixing and winding paper winding; S3: winding and winding paper winding material clamping; S4: winding paper winding and winding synchronization conveying; S5: winding paper tension control; S6: winding paper wrapping winding forming; S7: fixed-length cutting; S8: finished product detection and sorting; S9: infrared lamp tube shaping S10: equipment cleaning and maintenance; S11: false eyelash shaping quality detection and process optimization. In step S1, three rows of false eyelash semi-finished products are arranged on the winding paper.

[0018] In step S1, the winding paper is made of raw wood pulp paper, and the winding is made of food-grade PET winding.

[0019] In step S2, after the false eyelash semi-finished product is screened, the eyelash silk is combed by a special brush to ensure consistent direction and prevent eyelash silk from knotting.

[0020] In step S2, the false eyelash semi-finished product is pasted on the winding paper by high-temperature adhesive tape.

[0021] In step S9, the false eyelash shaping is performed by high-temperature shaping with an infrared lamp tube.

[0022] In step S11, the finished product detection is performed in the form of sampling inspection.

[0023] Further:

[0024] S1: screening qualified false eyelash semi-finished products for standby, and combing the eyelash silk with a special brush to prevent eyelash silk from knotting, testing whether the strength of the winding paper is qualified and whether the surface of the winding paper has defects, and screening a sufficient number of qualified windings for standby; ​S2: Wrap one end of the long roll of paper around the take-up reel and tighten the nut. Then lay the roll of paper flat on the processing table of the carding device and the high-temperature adhesive strip pulling device (the carding device is located between the take-up motor and the high-temperature adhesive strip pulling device), ensuring that the roll of paper is wrinkle-free and unstretched. Then start the take-up motor and the carding device of the high-temperature adhesive strip pulling device. The roll of paper is wound up at a uniform speed. At this time, the high-temperature adhesive strip pulling device pulls out strips of high-temperature adhesive from the roll of paper. The carding device uses a suction cup to pick up the semi-finished false eyelashes, and then... The finished product is moved to the high-temperature adhesive strip stretched on the roll paper. The false eyelashes are then glued onto the high-temperature adhesive strip in sequence to fix the false eyelashes to the roll paper (each set of false eyelashes is spaced 5-10cm apart, with the false eyelashes distributed in the middle of the roll paper and the two sides being the overlap of the roll paper so that the subsequent pressing rollers can roll over and press them together). Then, the roll paper with the false eyelash semi-finished products glued on is rolled up by the reel (after rolling up, the side of the roll paper with the false eyelash semi-finished products faces outwards). After rolling up, the roll material is protected with a protective film or protective box. S3: Manually pour the rolled tube into the vibratory feeder hopper of the rolling tube equipment (start the vibratory feeder), manually remove the protective film of the pre-made rolled material, put the rolled material on the unwinding roller, ensure that the false eyelashes face outwards (the hairs do not contact the roller), tighten the fastening nut, manually pull the end of the rolled paper, pass through the guide roller and alignment station, and send it into the forming machine (the process must be careful to ensure that the false eyelashes are not scratched), input the rolling tube conveying speed, the rolled paper conveying speed (the rolling tube conveying speed and the rolled paper conveying speed must be matched to ensure that the rolled tube can accurately land in the middle position on the rolled paper after conveying, and ensure that the semi-finished false eyelashes can be completely covered after rolling), cutting length, and pressing pressure through the control panel of the rolling tube equipment; S4: After preparation, start the equipment. The vibratory feeder vibrates, and the tube roll rises along the spiral track of the vibratory feeder. The track width only allows a single tube roll to pass through. The guide groove at the end of the vibratory feeder corrects the direction of the tube roll (positioning mark facing upwards). Tube rolls with incorrect direction are pushed back by pneumatic paddles. Qualified tube rolls fall into the positioning groove of the conveyor chain. The servo motor drives the conveyor chain to convey at an appropriate speed. The guide baffles on both sides ensure that the tube roll does not deviate. The photoelectric sensor detects whether there is a tube roll in the positioning groove. When there is a shortage of material, it sends a signal to the PLC system to pause the subsequent process to avoid empty rolls (at this time, when the PLC receives the signal that there is material in the tube roll conveyor chain, it starts the tube roll paper unwinding motor, and the tube roll paper is conveyed synchronously to ensure that the false eyelash semi-finished product on the tube roll paper corresponds one-to-one with the tube roll). The tube roll in the positioning groove is sent to the forming machine synchronously with the tube roll paper along the conveyor chain. The guide baffles on both sides of the conveyor chain form a channel constraint. If the tube roll is slightly skewed during conveying, the baffle will push it back to the center of the positioning groove to ensure that the posture is stable and will not deviate from the position of the false eyelash semi-finished product on the tube roll paper. S5: After receiving the material signal from the roll conveyor chain, the PLC starts the roll unwinding motor. Based on the roll diameter, it adjusts the speed according to the sensor signal (if the initial roll diameter decreases, the speed is increased accordingly to ensure the roll conveying speed is appropriate). The tension controller adjusts the unwinding tension in real time. If the tension is too high (e.g., the film is stretched), the sensor detects the tension value of the film when it passes the tension sensor guide roller. The sensor sends a signal to the PLC, which controls the unwinding motor to speed up, increasing the film output and reducing the tension. If the tension is too low (e.g., the film is loose and wrinkled), the motor speed slows down, reducing the output and increasing the tension to ensure the roll is flat and there is no displacement. If the roll deviates to the left or right, the photoelectric correction device pushes the unwinding shaft to move laterally and pull the roll back to the center path. S6: The tube and the tube paper enter the forming device. The arc-shaped guide surface on the inner wall of the forming device forces the tube paper to fold upward into a U-shape. The tube falls into the center of the U-shaped groove. The side guide plate of the forming device pushes the two sides of the tube paper to fold towards the center to form a tube. After the tube paper wraps the tube, the pressing roller rolls over the overlap of the tube paper to ensure that the overlap of the tube paper is tightly fitted. S7: The composite is conveyed to the cutting station. The rolled tube is recorded by the long encoder to record the moving distance. When the preset rolled tube length is reached, a cutting signal is sent to the cutting knife group. The cutting knife rotates (the rotation speed is synchronized with the rolling tube moving speed) to cut the rolled tube paper. The cut finished false eyelash rolled tube continues to be conveyed to the inspection station. S8: After cutting, the finished product passes through a vision sensor, which captures an image of the finished product. An AI algorithm then detects four types of defects. Tube roll inspection: Checking for any missing sections of the tube roll. False eyelash inspection: Condition of the paper roll pressing area (whether the paper roll pressing area is not pressed tightly or has an opening); Package inspection: Loose roll paper (whether the roll paper is tightly wrapped); Cutting inspection: Cutting offset (whether the cutting deviation exceeds the standard range); If a defective product is detected, the PLC sends a signal to the pneumatic pusher, which extends instantly, pushing the defective product into the waste bin. Qualified finished products continue to be conveyed along the conveyor belt to the infrared lamp irradiation station for high-temperature shaping. Defective finished products are manually disassembled and recycled along with intact false eyelashes. S9: The infrared lamp irradiation station consists of multiple infrared lamps. The temperature and irradiation time of these lamps can be adjusted via PLC. When the qualified semi-finished false eyelashes, after being rolled, move to the infrared lamp irradiation station, the lamps turn on and heat and shape the eyelashes. Using infrared lamps for shaping directly heats the false eyelashes, eliminating the need for preheating the entire steam chamber like in a steam oven. Infrared lamps heat up quickly, resulting in higher efficiency. The infrared lamps only heat the target area, eliminating excess heat waste and lowering long-term operating costs. Without the humidity effects of steam, the shaped false eyelashes have a uniform curl, are less prone to softening, and have a more durable and stable shaping effect. S10: After each use, the device needs to be cleaned and maintained. Use a hot air blower to blow away dust from the unwinding mechanism of the paper roll; use a cleaning cotton roller to wipe the cutting blade to remove residual paper rolls; calibrate the vision camera; check the offset and wear of each component, and adjust, repair or replace them in a timely manner. S11: After the false eyelashes are shaped by infrared lamp irradiation and cooled, a quality inspection is conducted. All key indicators (shape consistency, appearance defects) are inspected, and physical properties (20 pieces) and hygiene and safety (5 pieces) are sampled. For the first processing of new materials or with new parameters, regardless of batch size, 50 pieces must be fully inspected and 200 pieces sampled to ensure there are no systemic problems. If a product fails a random inspection, identify the problem and pinpoint its origin to prevent misalignment in adjustments. For identified issues, develop solutions categorized by priority (scope of impact) and adjustment range (whether shutdown is required), prioritizing problems with significant impact and ease of adjustment. Conduct small-scale production using optimized parameters, closely monitoring improvements to previously non-conforming items. Perform three consecutive trial production batches. If all three batches meet standards, proceed to the standardization phase. If fluctuations persist, re-investigate and improve the issues, then restart trial production.

[0025] Furthermore, when using rolls of different shapes later, the roll paper specifications can be selected according to the roll's specifications and shape. When producing a specific specification, simply select the corresponding parameters. This rolling method can effectively roll false eyelashes of different thicknesses, shapes, and sizes (it can adapt to different semi-finished false eyelash products at each processing stage. For example, adjusting the roll paper tension: thicker, stiffer false eyelashes require slightly higher tension to prevent loosening, while thinner, softer false eyelashes require less tension to prevent fiber breakage, etc. The rolls and roll paper can also be adapted to different semi-finished false eyelash products. For example, thinner, softer false eyelashes (such as natural styles) use roll paper made of virgin wood pulp, while thin / fine false eyelashes (requiring lightweight support) use rolls made of food-grade PP material, etc.). In addition, different specifications of rolls and roll paper need to be sorted and stored before rolling processing for easy subsequent use. Furthermore, when using different shaped tubes, the eyelash strands of the semi-finished false eyelashes after the tube is rolled will also form different shapes (such as L-shape, sunflower shape, etc.), thus enabling the creation of more different shapes of false eyelashes. The length of the tube is 1-2cm longer than each group of semi-finished false eyelashes, which can completely wrap the semi-finished false eyelashes on the tube. At the same time, there is a 5-10cm gap between each group of false eyelashes, leaving enough space to cut the tube paper. Furthermore, in addition to using virgin wood pulp paper (virgin wood pulp paper is soft and skin-friendly, and will not scratch the hairs when wrapping false eyelashes, and can also reduce friction on the skin around the eyes), other materials such as polyimide (PI) film can also be used for the roll tubes. In addition to using food-grade PET roll tubes (PET roll tubes are hard enough to keep the false eyelashes naturally curled and not bounce back), other materials such as food-grade PP can also be used, with different grades selected accordingly. Furthermore, the curling tubes and curling paper can be graded according to the value of the order and the grade of false eyelashes required by the customer. For example, if the order value is low or the customer requires lower quality false eyelashes, a lower-cost curling tube and curling paper can be used to curl the semi-finished false eyelashes. Alternatively, a lower-cost disposable curling tube and curling paper can be used to curl the false eyelashes, reducing processing costs. Similarly, when the order value is medium / high or the customer requires higher / lower quality false eyelashes, the appropriate material for the curling tube and curling paper can be selected. The better the material of the curling tube and curling paper, the better the quality of the semi-finished false eyelashes after curling, and consequently, the better the quality of the finished false eyelashes after high-temperature setting. Furthermore, after each batch of rolled false eyelashes is set at high temperature, the set false eyelashes are graded according to the rate of lash curling. The grading standards are as follows: lash curling rate ≤1% is high-end grade, lash curling rate ≤3% is medium standard grade, and lash curling rate ≤5% is low-end grade. False eyelashes of different grades are then boxed and packaged separately. Furthermore, the equipment and devices used in this application, the PLC control program / system, the algorithms, and the electrical connections between the devices are all prior art. The vibratory feeder device (e.g., adjustable track width to adapt to different tube diameters), the conveyor chain device (e.g., adjustable positioning groove width to adapt to changes in tube diameter), the wrapping and forming equipment (e.g., adjustable forming radius to adapt to changes in tube diameter), the cutting blade position adjustment (adapting to tube length), and the tension adjustment device (adapting to different materials of tube paper) all have varying degrees of position adjustment capabilities to adapt to the tube winding operation requirements of tubes with different diameters and lengths. These are prior art and will not be elaborated further here.
