Description

Technical Field

[0001] The utility model relates to the field of false eyelash preparation, in particular to a device for flattening and arranging false eyelash fibers. Background Art

[0002] As we all know, false eyelashes are a cosmetic product that beautifies the eyes by lengthening and thickening them, making them appear larger, fuller, and more vivid. Wearing false eyelashes can enhance and enhance the eyes, and can also be used to create various stage effects. Existing false eyelashes mainly include adhesive false eyelashes and grafted false eyelashes. Grafted false eyelashes are increasingly popular due to their realistic effect and long-lasting effect.

[0003] The existing false eyelash manufacturing process requires first forming bundles of false eyelashes into evenly arranged rows, which are then used for further processing to create marketable false eyelashes. The existing production process for false eyelash rows is mostly manual. The process involves placing a bundle (consisting of multiple) of false eyelash fibers on an alignment plate. The bundle is then manually flattened and aligned on the plate. The plate is machined with equidistant eyelash positioning grooves, each with a width that matches the fiber's width and allows for one fiber to fit within. During the manual flattening process, a fiber is inserted into each groove. Tape is then applied from the upper side of the plate to adhere to the fibers in the grooves. The tape is then removed from the plate, allowing the fibers to be removed, creating the row. The diameter of the false eyelash fibers ranges from approximately 0.05 mm to 0.2 mm. Manually laying the fibers flat on the plate and manipulating them is difficult, time-consuming, and labor-intensive, resulting in labor waste and low efficiency. Utility Model Content

[0004] The purpose of the utility model is to solve the deficiencies of the above-mentioned prior art and provide a false eyelash fiber flattening and arranging device which can automatically complete the flattening and arranging of false eyelash fibers, saves labor, has high production efficiency and low cost.

[0007] The eyelash flattening device comprises a flattening mounting seat, a flattening mounting plate is provided on the flattening mounting seat, a flat push plate which can slide left and right is provided on the front side of the flattening mounting plate, a height adjustment plate which can slide up and down is provided on the front side of the flat push plate, a flattening finger is installed on the front side of the height adjustment plate, a horizontal reset seat is provided on the right side of the flat push plate, a horizontal reset tension spring is provided between the flat push plate and the horizontal reset seat; an upper and lower reset seat plate which can slide up and down is provided on the front side of the horizontal reset seat, the upper and lower reset seat plate and the height adjustment plate can slide relative to each other left and right, a downward pressure reset tension spring is provided between the upper and lower reset seat plate and the flattening mounting seat; the right side of the flat push plate A rubbing shaft is installed on the rubbing mounting plate below the side and upper and lower reset seat plates via a bearing, and a push cam and a lifting cam are installed on the rubbing shaft, which respectively cooperate with the right side of the push plate and the lower side of the upper and lower reset seat plates. During operation, when the pushing part of the push cam contacts the right side of the push plate, the near rest part of the lifting cam contacts the lower side surface of the upper and lower reset seat plates; when the return part of the push cam contacts the right side of the push plate, the far rest part of the lifting cam contacts the lower side surface of the upper and lower reset seat plates; a rubbing drive motor is installed on the rear side of the rubbing mounting plate, and the output shaft of the rubbing drive motor is connected to the rubbing shaft;

[0008] The eyelash alignment device includes an alignment bracket. The alignment bracket, located above the linear transport device, is equipped with an alignment limit cylinder. The piston rod at the lower end of the alignment limit cylinder is equipped with a limit stop bar that mates with the upper side of the alignment plate. The alignment bracket is also equipped with a front and rear alignment cylinders. The piston rods of the front and rear alignment cylinders are connected to the front and rear alignment plates, respectively, which are located opposite the front and rear sides of the alignment plate. During operation, the alignment limit cylinder drives the limit stop bar downward to the upper side of the alignment plate, ensuring that the lower side of the limit stop bar is 0-0.05 mm away from the false eyelash fibers laid flat on the alignment plate. The front and rear alignment cylinders then drive the front and rear alignment plates to move relative to each other, aligning the false eyelash fibers.

[0009] Furthermore, a rubbing shaft support plate is provided on the front side of the rubbing mounting seat, and the front end of the rubbing shaft is mounted on the rubbing shaft support plate via a bearing, which makes the operation more stable. A height adjustment platform is provided on the lower side of the rubbing mounting seat, and the rubbing mounting seat is mounted on a workbench via the height adjustment platform, and the height can be adjusted according to specific working conditions during use.

[0010] The push plate described in this utility model has a push roller mounted on the right side that cooperates with a push cam, and a lift roller mounted on the upper and lower reset plates that cooperate with a lift cam. The push cam and lift cam respectively engage with the push roller and lift roller to push the push plate and the upper and lower reset plates, reducing friction and ensuring smooth operation.

[0011] The outer edge (of the flat push cam) corresponding to the pushing stroke of the flat push cam described in the present invention is in an involute shape (the radius gradually increases from the near rest end to the far rest end), and the central angle corresponding to the pushing stroke portion of the flat push cam is 180-270°, preferably 240-260°; the central angle corresponding to the return stroke portion is 180-90°, preferably 100-120°.

[0012] The eyelash alignment device is provided with a cleaning fan on one side, which is opposite to the upper side of the arrangement plate. The cleaning fan is set on the rear side of the arrangement plate and can blow excess false eyelash fibers on the arrangement plate to the front side of the workbench to avoid affecting the operation of the system.

[0013] The alignment plate includes an alignment base, with an elongated alignment substrate positioned above it. The alignment substrate also features equally spaced eyelash alignment grooves extending forward and backward. The width of the grooves is 1.01-1.2 times the (maximum) diameter of the false eyelash fibers, preferably 11 times. The depth of the grooves is greater than the radius of the false eyelash fibers (at their midpoint) and less than their diameter, typically 0.7-0.8 times their diameter, ensuring secure adhesion and stable alignment.

[0014] A further improvement is that an upwardly protruding alignment strip is located in the center of the upper side of the alignment base. The width of the alignment strip in the front-to-back direction is 0.1-0.2 times the width of the alignment base. The eyelash alignment groove is located on the alignment strip. The alignment strip cooperates with the underside of the smoothing finger. When the widths of the alignment strip and the smoothing finger are the same or slightly different, the false eyelash fibers can more easily enter the eyelash alignment groove, improving product quality. The front-to-back width of the alignment base is 0.8-1 times the length of the false eyelash fibers, which further enhances alignment.

[0015] During use, the present invention places a bundle of false eyelash fibers on the upper side of an arrangement plate. A linear transport device drives the arrangement plate to the eyelash flattening device, which cooperates with the arrangement plate to flatten and evenly distribute the false eyelash fiber bundle on the upper side of the arrangement plate. The linear transport device then drives the arrangement plate to the eyelash alignment device, which aligns the false eyelash fiber bundle in the front-to-back direction on the arrangement plate, completing the flattening and arrangement of the false eyelash fibers. The subsequent adhesive tape bonding process then begins, bonding the evenly distributed false eyelash fibers on the arrangement plate to form a row of false eyelashes. The present invention achieves automatic flattening and arrangement of false eyelash fibers, saving labor, improving production efficiency, and reducing production costs.

The front side of the flat push plate 034 is provided with a height adjustment plate 035 that can slide up and down. Figure 2 It can be seen from the above that a vertical slide rail arranged in the up and down direction is provided on the front side of the push plate 034, and the height adjustment plate 035 can be installed on the vertical slide rail so as to slide up and down. A flattening finger 037 whose lower side cooperates with the arrangement plate is installed on the left front side of the height adjustment plate 035 via a support arm 0353. The flattening finger 037 is L-shaped, and the lower bottom surface is a plane that cooperates with the upper side of the arrangement plate. A horizontal reset seat 0342 fixedly connected to the flattening mounting plate 033 is provided on the right side of the push plate 034, and a horizontal reset tension spring 0341 is provided between the push plate 034 and the horizontal reset seat 0342; an upper and lower reset seat plate 0351 that can slide up and down is connected on the front side of the horizontal reset seat 0342 via upper and lower reset slide rails. The upper and lower reset seat plate 0351 and the height adjustment plate 035 are connected in a limit connection that can slide left and right relative to each other. Figure 2 It can be seen that the upper front part of the height adjustment plate 035 is provided with a linkage slide rail arranged horizontally in the left and right directions, the right rear part of the upper and lower reset seat plate 0351 can be slid up and down and installed on the upper and lower reset slide rail, and the left rear part of the upper and lower reset seat plate 0351 can be slid left and right and installed on the linkage slide rail. A downward reset tension spring 0352 is provided between the connecting pin on the right side of the upper and lower reset seat plates 0351 and the connecting pin on the right side of the flattening mounting seat 032; a hair-rubbing shaft 0331 is installed on the front side of the flattening mounting plate 033 on the right side of the flat push plate 034 and below the upper and lower reset seat plates 0351 through a bearing, and the hair-rubbing shaft 0331 is installed with a flat push cam 039 and a lifting cam 038 that cooperate with the right side of the flat push plate 034 and the lower side of the upper and lower reset seat plates 0351 respectively. The upper and lower reset seat plates 0351 are located in front of the flat push plate 034, and a flattening drive motor 036 is installed on the flattening mounting seat 032 on the rear side of the flattening mounting plate 033, and the output shaft of the flattening drive motor 036 is connected to the hair-rubbing shaft 0331. During operation, when the push cam 039's forward stroke contacts the right side of the push plate, the near-rest portion of the lift cam 038 contacts the undersides of the upper and lower return plates. When the push cam 039's return stroke contacts the right side of the push plate, the far-rest portion of the lift cam 038 contacts the undersides of the upper and lower return plates. The far-rest angle of the lift cam 038 is 50°, and the near-rest angle is 250°. The central angles corresponding to the forward and return strokes are identical, both 30°.

[0027] The eyelash alignment device 02 is as follows Figure 9 As shown, it includes an alignment bracket 041, which is in a door shape and spans the linear transport device 1. An alignment limit cylinder 044 is provided on the alignment bracket above the linear transport device 1. The piston rod at the lower end of the alignment limit cylinder 044 is provided with a limit stop bar 043 arranged in the left and right directions and cooperating with the side surface of the arrangement plate. A front push cylinder 042 and a rear push cylinder 045 are provided on the alignment bracket 041. The piston rods of the front push cylinder 042 and the rear push cylinder 045 are respectively connected to a front push plate 048 and a rear push plate 047 opposite to the front and rear sides of the alignment base plate 21 of the arrangement plate; Figure 9 As can be seen, the piston rods of the front aligning cylinder 042 and the rear aligning cylinder 045 are each connected to an L-shaped connecting arm. The front aligning plate 048 and the rear aligning plate 047 are connected to the piston rods of the front aligning cylinder 042 and the rear aligning cylinder 045, respectively, via the L-shaped connecting arm. During operation, the alignment limit cylinder 044 drives the limit stop bar 043 downward to the upper side of the alignment plate, so that the lower side of the limit stop bar is 0-0.05 mm away from the false eyelash fibers laid flat on the alignment plate. The front aligning cylinder 042 and the rear aligning cylinder 045 drive the front aligning plate 048 and the rear aligning plate 047 to move relative to each other. The front aligning cylinder 042 first moves backward until it contacts the front side of the alignment base plate 21, then moves forward and separates from the front side of the alignment base plate 21. The rear aligning cylinder 045 then moves forward until it contacts the rear side of the alignment base plate 21, thereby aligning the false eyelash fibers.

[0028] This embodiment is further improved. An upwardly protruding arrangement strip 23 is provided in the center of the upper side of the alignment base plate 21. The width of the arrangement strip 23 in the front-to-back direction is 0.1-0.2 times the width of the alignment base plate in the front-to-back direction. The eyelash arrangement groove 22 is provided on the arrangement strip 23. The arrangement strip 23 cooperates with the lower side of the smoothing finger. When the widths of the two are the same or the difference is small, the false eyelash fibers are more easily inserted into the eyelash arrangement groove, thereby improving product quality. The width of the alignment base plate in the front-to-back direction is 0.8-1 times the length of the false eyelash fibers, which provides a better alignment effect. A hair-smoothing shaft support plate 0321 is provided on the front side of the smoothing mounting seat 032. The front end of the hair-smoothing shaft 0331 is mounted on the hair-smoothing shaft support plate 0321 via a bearing, which makes the operation more stable. A height adjustment platform 031 is provided on the lower side of the smoothing mounting seat 032. The smoothing mounting seat 032 is mounted on the workbench 3 via the height adjustment platform 031. During use, the height can be adjusted according to the specific working conditions. A push roller 0344 is mounted on the right side of the push plate 034, cooperating with a push cam 039. A lift roller 0354 is mounted on the lower rear side of the upper and lower reset base plates 0351, cooperating with a lift cam 038. The push cam 039 and lift cam 038 engage with the push roller 0344 and lift roller 0354, respectively, to propel the push plate and upper and lower reset base plates, reducing friction and ensuring smooth operation. The outer edge of the push cam 039, corresponding to its stroke, forms an involute with a radius that gradually increases from the near end to the far end. The central angle corresponding to the stroke of the push cam is 250°. When the outer edge of the push cam (from its axis) contacts the right side of the push plate at its furthest point, the outer edge of the lift cam begins to contact the underside of the upper and lower reset base plates at its furthest point. A purge blower is installed on one side of the eyelash alignment device 02, facing the upper side of the alignment plate. The cleaning fan is set at the rear side of the arrangement plate, which can blow the excess false eyelash fibers on the arrangement plate to the front side of the workbench to avoid affecting the operation of the system; before the cleaning fan works, the alignment limit cylinder 044 drives the limit stop bar 043 to move downward and press against the upper side of the false eyelash fibers to fix the false eyelash fibers in the eyelash arrangement groove 22.

[0029] The up, down, front, back, left and right in the utility model are based on Figure 1 Set the relative direction.

[0030] When the utility model is working, a bunch of false eyelash fibers are placed on the upper side of the arrangement plate. The arrangement plate is driven by the linear transport device 1 to move rightward to the position where it cooperates with the eyelash flattening device 01. The flattening drive motor of the eyelash flattening device 01 works. Under the cooperation of the horizontal reset spring 0341 and the downward reset spring 0352, the horizontal push cam 039 and the lifting cam 038 drive the flattening finger 037 to flatten the false eyelash fiber bundle on the upper side of the arrangement plate, so that the false eyelash fibers enter the eyelash arrangement groove 22 of the alignment substrate. The horizontal push cam 039 and the horizontal push cam 038 are aligned with each other. The return spring 0341 cooperates to drive the smoothing finger 037 to reciprocate horizontally. The lifting cam 038 cooperates with the downward return spring 0352 to drive the smoothing finger 037 to reciprocate vertically. The horizontal push cam 039, the lifting cam 038, the horizontal return spring 0341, and the downward return spring 0352 work together to achieve the repetitive movement of the smoothing finger 037, which simulates the repeated movement of the finger, lowering and lifting. This, in conjunction with the movement of the alignment plate, quickly embeds the false eyelash fibers into the eyelash arrangement grooves 22. The alignment plate moves rightward to the eyelash alignment device 02. The limit stop cooperates with the forward and backward push cylinders 042 and 045 to align all the false eyelash fibers in the eyelash arrangement grooves 22. The alignment plate moves rightward to disengage the eyelash alignment device, allowing the subsequent tape bonding process to begin. This utility model achieves automatic smoothing and alignment of false eyelash fibers, saving labor, improving production efficiency, and reducing production costs.
