Description

Technical Field

[0001] This invention relates to the field of false eyelash manufacturing, and more particularly to an automatic eyelash assembly system for semi-finished false eyelashes. Background Technology

[0002] We know that false eyelashes are a cosmetic product used to enhance the eyes by lengthening and thickening eyelashes, making them appear larger, fuller, and more expressive. Wearing false eyelashes can beautify the eyes, making them more captivating, and can also be used to create various stage effects. Currently available false eyelashes mainly include applied false eyelashes and eyelash extensions. Eyelash extensions are increasingly popular due to their realistic effects and long-lasting wear.

[0003] Existing false eyelash manufacturing processes mainly include handmade false eyelashes, semi-handmade false eyelashes, and machine-made false eyelashes. Semi-handmade false eyelashes, due to their balance of production efficiency and quality, occupy the majority of the market share. The semi-handmade false eyelash production process includes using tools to glue individual false eyelash fibers parallel and equidistantly into rows, and then overlapping at least two rows to form a single row. These steps typically involve manually laying a bundle (containing multiple false eyelash fibers) flat on an arranging board. The arranging board has equidistant eyelash positioning grooves, the width of which matches the width of the false eyelash fibers, allowing one fiber to be inserted. Then, a brush is used to sweep away excess false eyelash fibers from the arranging board. Adhesive tape is used to bond the false eyelash fibers from the upper side of the arranging board to the eyelash positioning grooves. The tape is then separated from the arranging board, removing the false eyelash fibers, resulting in a finished product. Figure 13 The image shows an eyelash strip. The State Intellectual Property Office published a utility model patent entitled "An False Eyelash Manufacturing Device," application number 202121271792.8, application date June 8, 2021. This patent describes another process for manufacturing eyelash strips using a tool composed of a base plate, a sealing plate, a comb, and a stamping plate. The eyelash strips produced by this process have a distance between adjacent false eyelash fibers that is not less than the diameter of the false eyelash fiber. Directly using this method for processing false eyelashes results in low density and poor quality of the finished product. Therefore, at least two strips are needed... Figure 13 The eyelashes shown are stacked and densely packed into a row, then cut into semi-finished false eyelashes of a set length, and transferred to the next processing step. The main body of the existing false eyelash fibers gradually tapers in diameter from back to front, forming the eyelash tip; the process of stacking and densely packing the two rows of eyelashes into a row is generally done manually. The false eyelash fibers 49 in the two rows of eyelashes are manually arranged parallel to each other (in the left and right direction) and alternately pasted onto the tape 50, so that the roots of two adjacent false eyelash fibers 49 are close together or very close to each other. After the false eyelash fibers are densely packed into a row, they are cut to the required length with a tool to form semi-finished false eyelashes, and then transferred to the next processing step.

[0004] The existing method of combining semi-finished false eyelashes has the drawbacks of low production efficiency, high labor intensity, and waste of manpower. In addition, manual combining can easily cause some adjacent false eyelash fibers to cross each other. Due to the different abilities of the workers, the product quality will be inconsistent, and even substandard products may be produced. Summary of the Invention

[0017] The specific structure of the material-carrying linear platform and the pressing linear platform described in this invention is as follows: It includes a slide rail and a driver. A slider capable of linearly moving along the slide rail is mounted on the slide rail, and a load plate is mounted on the slider. The driver is connected to the load plate and is used to drive the load plate to move on the slide rail. The driver can be a two-way cylinder, a ball screw driven by a servo motor, a two-way hydraulic cylinder, etc.

[0018] The lifting device described in this invention consists of four lifting cylinders mounted on a linear material-carrying platform, with the processing table mounted on top of the lifting cylinders. The eyelash arrangement positioning clamp comprises a long, narrow chuck plate positioned above the processing table and engaging with it. A chuck plate drive cylinder is located on the lower side of the processing table, and the moving part of the chuck plate drive cylinder is connected to the chuck plate. The moving part of the chuck plate drive cylinder causes the chuck plate to move downwards, clamping and positioning the eyelash arrangement by engaging with the upper and lower sides of the processing table; conversely, it releases the eyelash arrangement.

[0019] The material-carrying linear platform described in this invention is equipped with a cylinder support frame, and a cylinder mounting plate is fixedly installed on the cylinder support frame. Four lifting cylinders are installed on the cylinder mounting plate, and the lifting cylinders are magnetic couple rodless cylinders.

[0020] In operation, two rows of eyelashes are placed parallel to each other on the upper side of the processing table. Eyelash positioning clamps fix the eyelashes to the processing table. A roll of blended adhesive tape is installed on the tape mounting base. Driven by the tape drive roller and guided by the tape guide wheel, the blended adhesive tape (strip) enters the left and right positioning clamps and is clamped and positioned. At this time, the blended adhesive tape between the left and right positioning clamps is located on the upper side of the processing table, directly below the pressing roller, and the three are parallel to each other. The material-carrying linear platform moves forward until an eyelash is positioned below the blended adhesive tape between the left and right positioning clamps, with the blended adhesive tape located in front of the tape on that eyelash. The lifting device raises the processing table until the eyelashes are in contact with or very close to the lower side of the blended adhesive tape (less than 5 meters). (m); The pressing cylinder drives the pressing roller to press down on the upper side of the composite tape. The pressing linear platform moves back and forth, causing the pressing roller to roll back and forth, pressing the composite tape down and adhering it to the eyelash strip. Then the pressing cylinder works, driving the pressing roller to rise and separate from the composite tape. The pressing linear platform moves backward, causing the eyelash fiber cutter of the eyelash fiber cutting device to face the eyelash strip between the composite tape and the tape on the eyelash strip. The cutter cylinder works, driving the eyelash fiber cutter to descend and cut the false eyelash fibers of the eyelash strip between the composite tape and the original tape on the eyelash strip. Then the eyelash fiber cutter moves upward to reset. The lifting device works, driving the processing table to descend, and the composite tape adhering to the cut false eyelash fibers at the front part of the eyelash strip (including the eyelash tip) separates from the processing table. The linear platform moves forward until another eyelash row is positioned below the adhesive tape between the left and right positioning jaws, with the adhesive tape located in front of the tape on the eyelash row. The lifting device raises the processing table until the eyelash row is in contact with or very close to the underside of the adhesive tape (less than 5mm). The pressing cylinder drives the pressing roller to press down on the upper side of the adhesive tape, pressing the false eyelash fibers already adhered to the adhesive tape between the false eyelash fibers of the other eyelash row. The pressing linear platform moves back and forth, causing the pressing roller to roll back and forth, pressing the adhesive tape down between each of the false eyelash fibers of the other eyelash row. The false eyelash fibers are bonded together; then the pressing cylinder operates, driving the pressing roller to rise and separate from the bonding tape; the pressing linear platform moves backward, driving the eyelash fiber cutter of the eyelash fiber cutting device to align with the eyelash strip between the bonding tape and the tape on the original eyelash strip; the cutter cylinder operates, driving the eyelash fiber cutter downward to cut the false eyelash fibers of another eyelash strip, and then driving the eyelash fiber cutter upward to reset; the lifting device operates, driving the processing table to descend, and the bonding tape, adhering to the front part of the cut eyelash strip (including the eyelash tip), separates from the processing table.The traction cylinder drives the tape gripper to move to the left to the right side of the right positioning gripper. The tape gripper clamps the right end of the composite tape on the right side of the right positioning gripper. The left and right positioning grippers open and release the composite tape. The traction cylinder moves to the right, driving the tape gripper to pull the composite tape with the adhering false eyelash fibers to the right. At this time, the tape supply device provides composite tape between the left and right positioning grippers. Then, the left and right positioning grippers clamp the newly entered composite tape. The shearing blade works, cutting the composite tape on the right side of the right positioning gripper. The cut composite tape has a clamping section on the right side of the right positioning gripper that cooperates with the tape gripper. The composite tape section held by the tape gripper is the semi-finished false eyelash with the composite texture completed. The semi-finished false eyelash enters the subsequent process to complete the subsequent processing of the false eyelash. This invention automatically completes the composite work of two rows of eyelashes, with high mechanical processing efficiency and labor saving. Attached Figure Description

A slider that can move linearly along the slide rail is mounted on the slide rail, and a load plate is mounted on the slider. The driver is connected to the load plate and is used to drive the load plate to move and position on the slide rail. The driver can be a two-way cylinder, a ball screw driven by a servo motor (i.e., an electric cylinder), a two-way hydraulic cylinder, etc. The material-carrying linear platform can also be a linear guide slide table as in the prior art. The lifting device has four lifting cylinders on the load plate of the linear material loading platform, and the processing table is installed on the upper end of the lifting cylinders. In this embodiment, the load plate of the linear material loading platform has a cylinder support frame 10, and a cylinder mounting plate 18 is fixedly installed on the cylinder support frame 10. Four lifting cylinders are installed on the cylinder mounting plate 18. The lifting cylinders are magnetic couple rodless cylinders. The cylinder mounting plate 18 has four vertically penetrating mounting holes. The moving body 11 of the magnetic couple rodless cylinder is fixedly connected to the mounting holes on the cylinder mounting plate 18, and the cylinder moves up and down relative to the moving body.

The eyelash positioning clamp has elongated chuck plates 17 on the left and right sides above the processing table 16, which cooperate with it. A chuck plate driving cylinder 22 is provided on the lower side of the processing table 16. The chuck plate driving cylinder 22 is a magnetic couple rodless cylinder. The cylinder barrel of the chuck plate driving cylinder 22 is fixed on the lower side of the processing table. The moving part of the chuck plate driving cylinder 22 is connected to the chuck plate. The moving part of the chuck plate driving cylinder drives the chuck plate to move downward, which can clamp and position the eyelashes on the upper side of the processing table; otherwise, the eyelashes can be released.

[0035] The support frame 9 is installed on the front of the workbench 12 outside the material-carrying linear platform; the material-carrying linear platform can move freely back and forth inside the support frame 9.

[0036] The tape supply device includes a mounting plate 20, a tape mounting seat 21 for mounting tape rolls, and tape guide wheels. The mounting plate 20 is located on the left side of the workbench and is fixedly connected to the workbench and support frame 9. The tape guide wheels are rotatably mounted on the front side of the mounting plate 20. In this embodiment... Figure 10 The tape mounting bracket shown includes a rotating base, a front baffle, and a rear baffle. The rotating base is rotatably mounted on the front side of the mounting plate, the rear baffle is fixed to the rear side of the rotating base, and the front baffle is detachably connected to the front side of the rotating base. The tape roll can be sleeved on the rotating base, and the front and rear baffles axially limit the tape roll. In this embodiment, the front baffle is connected to the front side of the rotating base by screws or to the rear of the rotating base by threads. The tape mounting bracket can also be a conventional tape base.

[0037] The aforementioned stacking and pressing device includes a pressing linear platform that moves horizontally in the front-to-back direction, a tape positioning gripper, a pressing device, and an eyelash fiber cutting device. The pressing linear platform is mounted on a support frame 9 above the material processing table. As shown in the figure, the pressing linear platform includes a slide rail and a driver. A slider that can move linearly along the slide rail is mounted on the slide rail, and a load plate 8 is mounted on the slider. The driver is connected to the load plate 8 and is used to drive the load plate 8 to move and position on the slide rail. The pressing linear platform has the same structure as the material loading linear platform and can be a linear guide slide table in the prior art. The tape positioning grippers include a left positioning gripper and a right positioning gripper 52. The left and right positioning grippers 52 are pneumatic grippers and are horizontally mounted on the support frames 9 on the left and right sides of the material processing table, respectively. The tape supplied by the tape supply device is guided by the tape guide wheel and then horizontally enters between the left and right positioning grippers 52 for clamping and positioning. The tape between the left and right positioning grippers 52 (i.e., the wool tape) is located on the left and right sides of the upper side of the processing table 16. The pressing device is a pressing cylinder 5 installed on the upper side of the load plate 8 of the pressing linear platform via a support plate 4. The lower end of the piston rod 6 of the pressing cylinder 5 is connected to a pressing roller arranged in the left and right direction and cooperating with the processing table 16. The eyelash fiber cutting device is a cutting cylinder 1 installed on the upper side of the load plate 8 of the pressing linear platform. The lower end of the piston rod of the cutting cylinder 1 is equipped with an eyelash fiber cutter 29 arranged in the left and right direction and cooperating with the processing table 16.

[0038] The automatic feeding device includes a traction cylinder 15 and a shearing blade. The traction cylinder 15 is a magnetic coupler-type rodless cylinder. The cylinder barrel of the traction cylinder 15 is mounted on the support frame 9 to the right of the right positioning gripper 52 via a support frame in a left-right direction. A tape gripper 46, which cooperates with the right positioning gripper 52, is installed on the moving body of the traction cylinder 15. The tape gripper 46 can clamp the end of the tape to the right of the right positioning gripper 52, and pull the tape to the right under the drive of the traction cylinder 15. The shearing blade is mounted on the support frame to the right of the right positioning gripper. The shearing blade can cut the tape that is clamped by the tape gripper and pulled to the right. Figure 12 As can be seen from the above, the shearing blade includes a pneumatic scissors 48 and a lifting drive cylinder 47. The pneumatic scissors 48 are installed on the lower right side of the right positioning jaw via the lifting drive cylinder 47. The lifting drive cylinder 47 can drive the pneumatic scissors 48 to rise and fall. After the pneumatic scissors rise and cut the tape on the right side of the right positioning jaw, the pneumatic scissors fall to the lower right side of the right positioning jaw to prevent them from affecting the operation of other components.

[0039] When working, place the two rows as Figure 13 The eyelash rows shown (eyelash row one and eyelash row two) are placed parallel to each other on the upper side of the processing table; as shown Figure 15 As shown, multiple rows can be arranged as follows Figure 13The false eyelash fibers 49 of the eyelash strip shown are arranged with the eyelash tips facing forward and parallel to each other on a base paper. The two ends of the tape 50 on the eyelash strip are attached to the paper. The paper is placed on the upper side of the processing table for easy operation. The eyelash positioning clamp fixes the eyelash comb to the processing table. The wool tape roll is installed on the tape mounting base 21. The wool tape (strip) 51 of the wool tape roll is guided by the tape guide wheel and enters the left and right positioning jaws 52, where it is clamped and positioned. At this time, the wool tape between the left and right positioning jaws 52 is located on the upper side of the processing table and directly below the pressing roller 27, with all three parallel to each other. The material-carrying linear platform moves forward until the eyelash comb is located below the wool tape 51 between the left and right positioning jaws 52, with the wool tape 51 positioned in front of the tape on the eyelash comb. The lifting device raises the processing table until the false eyelash fibers of the eyelash comb are in contact with or very close to the lower side of the wool tape (less than 5mm). The pressing cylinder drives the pressing roller to press down on the wool tape. On the upper side of the adhesive tape, the pressing linear platform moves back and forth, driving the pressing roller to roll back and forth, pressing the adhesive tape 51 down and adhering it to each false eyelash fiber of the eyelash row 1; then the pressing cylinder works, driving the pressing roller to rise and separate from the adhesive tape; the pressing linear platform moves backward, driving the eyelash fiber cutter of the eyelash fiber cutting device to face the eyelash row 1 between the adhesive tape and the tape on the original eyelash row 1; the cutter cylinder works, driving the eyelash fiber cutter to descend and cut the false eyelash fibers of the eyelash row 1 between the adhesive tape and the tape on the original eyelash row 1, then driving the eyelash fiber cutter to rise and reset; the lifting device works, driving the processing table to descend, and the adhesive tape adhering to the cut false eyelash fibers at the front part (including the eyelash tip) of the eyelash row 1 separates from the processing table. The linear platform moves forward until the second eyelash row is positioned below the adhesive tape between the left and right positioning jaws, with the adhesive tape located in front of the tape on the second eyelash row. The lifting device raises the processing table until the false eyelash fibers of the second eyelash row are in contact with or very close to the underside of the adhesive tape. The pressing cylinder drives the pressing roller to press down on the upper side of the adhesive tape 51, pressing the false eyelash fibers already bonded to the adhesive tape 51 between the false eyelash fibers of the second eyelash row. The pressing linear platform moves back and forth, causing the pressing roller to roll back and forth, pressing the adhesive tape down to bond with each false eyelash fiber of the second eyelash row. The rear pressing cylinder operates, driving the pressing roller to rise and separate from the adhesive tape; the pressing linear platform moves backward, driving the eyelash fiber cutter of the eyelash fiber cutting device to face the eyelash row two between the adhesive tape and the tape on the original eyelash row two; the cutter cylinder operates, driving the eyelash fiber cutter to descend and cut the false eyelash fibers of the eyelash row two between the adhesive tape and the tape on the original eyelash row, and then driving the eyelash fiber cutter to rise and reset; the lifting device operates, driving the processing table to descend, and the false eyelash fibers of the adhesive tape adhering to the front part of the eyelash row one and the cut front part of the eyelash row two (including the eyelash tip) are separated from the processing table.The traction cylinder drives the tape gripper to move to the left to the right side of the right positioning gripper. The tape gripper clamps the right end of the composite tape on the right side of the right positioning gripper. The left and right positioning grippers open and release the composite tape. The traction cylinder moves to the right, driving the tape gripper to pull the composite tape with the adhering false eyelash fibers to the right. At this time, the tape supply device provides a new section of composite tape between the left and right positioning grippers. Then, the left and right positioning grippers clamp the newly entered composite tape. The shearing blade works, cutting the composite tape on the right side of the right positioning gripper. The cut composite tape has a clamping section on the right side of the right positioning gripper that cooperates with the tape gripper. The composite tape section held by the tape gripper is the semi-finished false eyelash with the composite texture completed. The semi-finished false eyelash enters the subsequent process to complete the subsequent processing of the false eyelash. This invention automatically completes the composite work of two rows of eyelashes, with high mechanical processing efficiency and labor saving.

[0040] This embodiment is further improved, and the tape supply device is as follows: Figure 9 , Figure 10As shown, it also includes a belt drive roller and a belt release motor 37; the belt drive roller is installed on the front side of the mounting plate 20, and the belt release motor 37 is installed on the rear side of the mounting plate 20. The output shaft of the belt release motor 37 is connected to the upper drive roller 43 of the belt drive roller 44 via a reducer and is rotatably mounted on the front side of the mounting plate 20. The shaft of the upper drive roller 43 is connected to the output shaft of the belt release motor 37 via a reducer. The mounting plate 20 below the upper drive roller 43 is provided with a mounting groove. A pressure adjusting seat 19 that can slide up and down is installed in the mounting groove. The mounting plate 20 below the pressure adjusting seat 19 is provided with a pressure adjusting bolt 42 that can push the pressure adjusting seat 19 to move upward. The lower adjusting pressure roller 44 is arranged on the pressure adjusting seat 19 in cooperation with the upper drive roller. The mounting plate 20 on the right side of the conveyor belt drive roller 43 is provided with a buffer groove 39 that is vertically oriented and extends through the front and back. A buffer slider 40 that can slide freely up and down is provided within the buffer groove 39. As shown in the figure, a vertical guide rod 38 is provided on the mounting plate 20 behind the buffer groove, and the buffer slider 40 is mounted on the guide rod 38, allowing it to slide freely up and down. A buffer wheel 45 is provided on the front side of the buffer slider 40. A left guide wheel 53 and a right guide wheel 54 are respectively provided on the mounting plates 20 on the upper left and right sides of the buffer groove 39. The left guide wheel 53 and the right guide wheel 54 are the aforementioned conveyor belt guide wheels, which correspond to and cooperate with the left positioning jaw, the right positioning jaw 52, ​​and the conveyor belt jaw 46 in the left-right direction. A position sensor 41 that cooperates with the buffer slider 40 is provided on the lower rear side of the mounting plate 20. The conveyor belt drive roller is positioned between the conveyor belt mounting base 21 and the buffer wheel 45. The upper drive roller is made of a material that does not easily stick to the adhesive side of the tape; the upper drive roller can also be made by adding an anti-adhesion release agent layer or anti-adhesion coating to a rubber wheel. During operation, the tape release motor 37, the position sensor 41 and the controller are connected. The tape stretched from the tape roll, with the adhesive side facing up, enters between the upper drive roller 43 and the lower pressure roller 44 from the left side. The distance between the upper drive roller 43 and the lower pressure roller 44 is adjusted by the pressure adjusting bolt 42, so that the upper drive roller and the lower pressure roller exert appropriate pressure on the tape. When the tape release motor drives the upper drive roller to rotate, it can pull the tape roll to rotate and release the tape. The tape output from the right side of the upper drive roller and the lower pressure roller passes through the left guide wheel, the buffer wheel and the right guide wheel in sequence before being output to the left positioning gripper and the right positioning gripper. The length of the tape between the left guide wheel and the right guide wheel is greater than the length of the tape between the left positioning gripper and the right positioning gripper.When the traction cylinder moves the felted conveyor belt to the right, the buffer wheel drives the buffer slider to move upward quickly, rapidly supplying felted conveyor belt between the left and right positioning grippers. Once the controller detects the buffer slider moving upward and out of its detection range via the position sensor, it controls the conveyor belt release motor to operate, driving the upper drive roller to rotate and output felted conveyor belt to its right. When the controller detects the buffer slider falling and entering its right detection range via the position sensor, it controls the conveyor belt release motor to stop operating. This conveyor belt supply device has the advantages of buffering the felted conveyor belt, preventing damage due to excessive force, rapidly increasing the conveyor belt's capacity, high working efficiency, and good stability.

[0041] This embodiment is further improved, such as Figure 2 , Figure 4 , Figure 5 , Figure 6The pressing device shown has two pressing slide shafts 24 that can slide freely up and down on the load plate 8 of the pressing linear platform via bushings. A lower spring-loaded seat plate 14, horizontally arranged in the left-right direction, is fixedly installed at the upper end of the two pressing slide shafts 24. An upper spring-loaded seat plate 7, which cooperates with the lower spring-loaded seat plate 14, is provided at the lower end of the piston rod of the pressing cylinder 5. Four compression springs 23 are provided between the upper and lower spring-loaded seat plates 7 and 7. Limiting plates 56 are fixedly installed at the left and right ends of the lower spring-loaded seat plate 14. Each limiting plate 56 has a spring-loaded groove 55, and a limiting stop pin 57, which can slide freely up and down within the groove and is connected to the upper spring-loaded seat plate 7, is provided within it. A lower pressing strip plate 25 is fixedly installed at the lower end of the two pressing slide shafts 24. A left connecting support arm 28 and a right connecting support arm 26, extending symmetrically in the front-back direction, are provided at the left and right ends of the lower pressing strip plate 25. A connecting rod is provided below the lower pressing strip plate 25 to cooperate with it, but there is no direct connection between them. The system includes a floating rolling shaft 27, with its two ends mounted on a left rolling bearing seat 32 and a right rolling bearing seat via bearings. A left floating front tension spring 33 and a left floating rear tension spring 31 are respectively provided between the front and rear parts of the left rolling bearing seat 32 and the front and rear ends of the left connecting support arm 28. The left rolling bearing seat 27 is connected to the left connecting support arm 28 via the left floating front tension spring 33 and the left floating rear tension spring 31. The left rolling bearing seat 32 can move back and forth within the elastic range of the left floating front tension spring and the left floating rear tension spring. A right floating front tension spring and a right floating rear tension spring are respectively provided between the front and rear parts of the right rolling bearing seat and the front and rear ends of the right connecting support arm. The right rolling bearing seat is connected to the right connecting support arm via the right floating front tension spring and the right floating rear tension spring. The right rolling bearing seat can move back and forth within the elastic range of the right floating front tension spring and the right floating rear tension spring. When not subjected to external force, the floating rolling shaft 27 is located directly below the lower pressure plate 25.When the piston rod of the pressing cylinder 5 moves downward, it elastically presses down the lower pressing plate in the vertical direction through the upper pressing plate and the pressing spring. The lower pressing plate drives the lower pressing strip and the floating roller shaft to move downward through the pressing slide shaft. When the floating roller shaft is obstructed by pressing the pressing tape and / or false eyelash fibers, the lower pressing strip can continue to move downward and elastically press against the upper side of the floating roller shaft, providing it with a gentle downward pressure. The load plate of the pressing linear platform moves back and forth. Under the action of the left floating front tension spring, the left floating rear tension spring, the right floating front tension spring, and the right floating rear tension spring, the floating roller shaft presses against the pressing tape and / or false eyelash fibers. The upper side of the eyelash fibers is gently rolled and pressed. When the floating roller encounters different resistances, it can roll and / or slide relative to the adhesive tape and / or false eyelash fibers. The external force applied by the floating roller to the adhesive tape and / or false eyelash fibers is gentle and stable, avoiding damage to the false eyelash fibers. After 2 to 5 back-and-forth rolling, the adhesive tape and false eyelash fibers can be firmly bonded. When the false eyelash fibers of the first row of eyelashes, which are already bonded to the adhesive tape, are pressed down between the false eyelash fibers of the second row of eyelashes, if the false eyelash fibers of the first row of eyelashes and the false eyelash fibers of the second row of eyelashes intersect, the external force applied to the intersecting false eyelash fibers during the back-and-forth rolling of the floating roller changes gently. This makes it easier for the intersecting false eyelash fibers to slide relative to each other to a parallel position, making it less likely to damage the intersecting false eyelash fibers and improving the quality of the product.

[0042] from Figure 2 , Figure 7 and Figure 8 As can be seen from this, this embodiment has been further improved, such as... Figure 7 , Figure 8The described eyelash fiber cutting device has a left adjusting slide 3 and a right adjusting slide on the upper side of the load plate 8 of the pressing linear platform. The upper surfaces of the left and right adjusting slides are arc-shaped sliding surfaces that slope downwards from front to back. The upper surfaces of the left and right adjusting slides are respectively provided with arc-shaped dovetail grooves 34 parallel to them. The left and right adjusting slides are respectively provided with left mounting sliders 2 and right mounting sliders that mate with their upper surfaces and can slide freely. The lower surfaces of the left and right mounting sliders are arc-shaped sliding surfaces that mate with the upper surfaces of the left and right adjusting slides. The lower surfaces of the left and right mounting sliders are respectively provided with (dovetail-shaped) limiting sliders 35 that mate with the dovetail grooves 34. The limiting sliders 35 can slide freely along the dovetail grooves 34. The left and right mounting sliders are positioned relative to the left and right adjusting slides 3 and the right adjusting slides. Each component is equipped with a quick-locking device. The quick-locking device includes a locking screw and a control handle 13. The left and right mounting sliders each have a through-hole locking screw along the radial direction of the arc-shaped sliding surface. Two locking screws and the locking screw holes are threadedly installed on the left and right mounting sliders. In use, rotating the locking screw forward causes its lower end to press against the bottom surface of the dovetail-shaped groove, pressing the limiting slider firmly into the dovetail-shaped groove. Rotating the locking screw in the reverse direction separates its lower end from the bottom surface of the dovetail-shaped groove, allowing the limiting slider to slide back and forth within the groove. The control handle 13 is installed on the upper end of the locking screw for operating it. Alternatively, the quick-locking device can have locking bolts on the sides of the left and right adjusting slides opposite to the limiting slider. These bolts can abut against the limiting slider to lock it to the left and right adjusting slides. The cutting cylinder is installed on the left and right mounting sliders. Figure 7 , Figure 8As can be seen, the left mounting slider 2 and the right mounting slider are provided with cutting mounting plates 36 on their front sides, and the cutter cylinder 1 is fixed on the cutting mounting plates 36; the load plate 8 of the pressing linear platform between the left adjusting slide 3 and the right adjusting slide is provided with a vertically penetrating cutting groove 30, and the lower end of the piston rod of the cutter cylinder 1 extends through the cutting groove 30 to the lower side of the load plate of the pressing linear platform and is connected to the eyelash fiber cutter 29; the upper sides of the left adjusting slide 2 and the right adjusting slide are on the same cylindrical surface, and when the eyelash fiber cutter 29 is in the initial cutting position (the position before the cutter cylinder drives the eyelash fiber cutter to cut), the blade of the eyelash fiber cutter 29 coincides with the axis of the cylindrical surface on which the upper sides of the left adjusting slide and the right adjusting slide are located. When the left and right mounting sliders are located in front of the left and right adjusting slides, the piston rod of the cutter cylinder is in a vertical position, perpendicular to the axis of the false eyelash fiber. At this time, the eyelash fiber cutter can cut the false eyelash fiber radially, and the cutting surface is the cross-section of the false eyelash fiber. Moving the left and right mounting sliders backward on the left and right adjusting slides can adjust the angle between the piston rod of the cutter cylinder and the axis of the false eyelash fiber. The eyelash fiber cutter can cut the false eyelash fiber at an angle, and the cutting surface is a plane at an acute angle to the axis of the false eyelash fiber. When the left and right mounting sliders are located behind the left and right adjusting slides, the minimum angle between the piston rod of the cutter cylinder and the axis of the false eyelash fiber is 30°. The eyelash fiber cutter can cut an inclined cutting surface with a 30° angle to its axis on the false eyelash fiber. The area of ​​the inclined cutting surface is increased, which increases the connection area between the false eyelash fiber and the real eyelash, making the grafting more secure, less prone to loosening and falling off, and reducing the difficulty of operation during grafting. The tilt angle of the eyelash fiber cutter can be adjusted as needed. During the adjustment process, the relative position of the blade of the eyelash fiber cutter and the processing table does not change. The adjustment is simple, convenient and efficient.
