Description

Technical Field

[0001] The utility model relates to the field of false eyelash preparation, in particular to a device for automatically bonding upper and lower adhesive tapes of a false eyelash row. 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 first requires bundles of false eyelashes to be formed into evenly arranged rows. The rows are then used for further processing to create marketable false eyelashes. Existing rows consist of false eyelash fibers and adhesive tape. The fibers are arranged parallel to each other and equidistantly, secured to two layers of tape. The production process for existing false eyelash rows is often manual. The process involves laying a bundle (consisting of multiple) of false eyelash fibers flat on an arrangement plate with equidistant eyelash positioning grooves. The grooves are designed to fit the fibers, allowing one to fit within. Excess fibers are then brushed off the plate with a brush. A section of adhesive tape is then manually cut and bonded from the top of the plate to the fibers in the grooves. The tape is then separated from the plate, removing the fibers. The remaining tape is then manually cut and bonded to the underside of the fibers to create the false eyelash row. Existing production processes for false eyelash rows often involve high labor costs, low production efficiency, and high costs. Utility Model Content

[0032] When the present invention is working, a bundle of false eyelash fibers is placed on the upper side of the arrangement plate, and the false eyelash fiber bundle is rubbed flat, evenly distributed and aligned front to back on the upper side of the arrangement plate manually or mechanically, and the linear transfer device drives the arrangement plate to move rightward to the lower side of the front and rear transfer bonding device 05, and the first positioning clamping jaw 071 clamps the end of the upper tape output by the first tape supply unit, and the left and right translation cylinder 072 drives the first positioning clamping jaw 071 to move leftward, so that the clamping head of the first positioning clamping jaw 071 drives the upper tape to move to the left side of the clamping head of the dragging clamping jaw 0533 (the dragging clamping jaw 0533 is located on the left side of the fixed clamping jaw 0534, and the clamping heads of the two are close to each other). At this time, the first shearing knife 074 is in the position On the lower right side in front of the fixed clamping jaw 0534; the clamping heads of the fixed clamping jaw 0534 and the dragging clamping jaw 0533 are opened, and the two clamping fingers of the clamping heads are respectively located on the upper and lower sides behind the upper tape; the driving device of the front and rear transport bonding device 05 works, and the driving pulley 051 drives the driving belt 057 to rotate forward, and the driving belt 057 drives the transport mounting plate 052 to slide forward on the four slide rails 056 to the position where the two clamping fingers of the clamping heads of the fixed clamping jaw 0534 and the dragging clamping jaw 0533 can clamp the upper tape, the clamping head of the dragging clamping jaw 0533 is closed and clamps the upper tape, the clamping head of the first positioning clamping jaw 071 is opened, and the left and right translation cylinder 072 drives the first positioning clamping jaw 071 to the right Move to the right side of the first shearing knife 074, drag the clamping jaw 0533 to the left, drag the upper tape to the required length, the fixed clamping jaw 0534 and the chuck of the first positioning clamping jaw 071 are closed, clamping the upper tape, at this time the first shearing knife 074 is located below between the chuck of the fixed clamping jaw 0534 and the first positioning clamping jaw 071, the first shearing knife 074 works, cuts the upper tape between the fixed clamping jaw 0534 and the first positioning clamping jaw 071 and then resets; the driving device of the front and rear transport bonding device 05 works, the driving pulley 051 drives the driving belt 057 to rotate in the opposite direction, and the driving belt 057 drives the transport mounting plate 052 to slide backward on the four slide rails 056 to the fixed The upper tape strip clamped by the clamping jaw 0534 and the dragging clamping jaw 0533 is located above the arrangement plate, and the bonding lifting cylinder 0521 drives the bonding installation plate 053 to move downward. The upper tape strip clamped by the fixed clamping jaw 0534 and the dragging clamping jaw 0533 covers the false eyelash fiber row on the upper side of the arrangement plate. The compacting cylinder 0531 drives the compacting strip 0532 to press down, and the upper tape strip between the fixed clamping jaw 0534 and the dragging clamping jaw 0533 is tightly pressed and bonded to the upper side of the false eyelash fiber row, so that the upper tape strip sticks to each false eyelash fiber in the false eyelash fiber row. The compacting strip 0532 rises and the bonding installation plate 053 moves upward, and the upper tape strip drives the false eyelash fiber row to move up away from the arrangement plate.The second positioning clamp 064 clamps the lower tape output by the second tape supply unit, and the end of the lower tape extends out of the left side of the clamp of the second positioning clamp 064, the clamp of the drag-out clamp 067 is opened, and the drag-out drive cylinder 062 drives the drag-out slide 068 to move to the right until the clamp of the drag-out clamp 067 can clamp the end of the lower tape. At this time, the second tape pasting platform 066 is located below the second positioning clamp, the clamp of the drag-out clamp 067 is closed and clamps the end of the lower tape, the clamp of the second positioning clamp 064 is opened, the drag-out drive cylinder 062 drives the drag-out clamp 067 to move to the left and drags the lower tape to the required length to the left. The dragged lower tape is located on the upper side of the second tape pasting platform 066, and the second positioning clamp 064 The clamping head of the dragging jaw 067 is closed and clamps the second tape; the second shearing knife 065 works to cut the second tape between the dragging jaw 067 and the second positioning jaw 064 to obtain the lower tape strip, the length of the lower tape strip is less than the length of the upper tape strip between the fixed jaw 0534 and the dragging jaw 0533; the clamping head of the dragging jaw 067 is opened, and the front and rear transport bonding device drives the upper tape strip bonded with the false eyelash fiber row to move above the lower tape strip, and the bonding lifting cylinder 0521 drives the upper tape strip and the false eyelash fiber row to cover the lower tape strip on the upper side of the second tape pasting platform 066, and the compacting cylinder 0531 drives the compacting strip 0532 to press down, pressing the lower side of the false eyelash fiber row tightly and bonding it to the upper side of the lower tape strip to form a false eyelash row. The compacting strip 0532 rises, the bonding and mounting plate 053 moves upward, and the front-to-back transport and bonding devices drive the row of false eyelashes to the top of the arrangement support device 6, which is covered with cardboard. The bonding and mounting plate 053 moves downward until the row of false eyelashes contacts the cardboard. Two downward pressure cylinders 0536 drive the downward pressure head 0535 downward, pressing and bonding the upper tape strips that extend beyond the left and right sides of the lower tape strip to the cardboard. The fixed and dragging jaws open, forming a row of false eyelashes. This ingenious design achieves automatic bonding of the tape strips on the upper and lower sides of the row of false eyelashes, saving labor, improving production efficiency, and reducing production costs.
