Description

[Technical field]

[0001] The invention relates to the technical field of zippers, and in particular to a glue-pressing edge sealing structure and a glue-pressing method for a multi-color mixed striped zipper. [Background technology]

[0002] Zippers are connectors that rely on continuously arranged chain teeth to connect or separate items. They are widely used in clothing, boxes, bags and other items.

[0003] Zippers are divided into single-open-end zippers, double-open-end zippers and closed-end zippers according to their different usage methods. Among them, the head or tail of single-open-end zippers and double-open-end zippers need to be sealed with hot-pressed matte glue to improve the strength of the head or tail of the open-end zipper.

[0004] The glue-stamping patterns of existing open-end zippers all use straight-grained edge-sealing patterns with all four edges fully sealed, such as the glue-stamping edge-sealing structure of a zipper tape and an open-end zipper disclosed in the Chinese utility model patent with application number CN202223392188.8. However, when it comes to zippers with multi-color mixed striped tapes, since the colors of the yarn-dyed stripes are usually contrasting colors with a large difference in depth, such as red and white, and are also different from the original color of the tape, the use of the above glue-stamping edge-sealing structure can easily cause the produced zippers to appear black or have mixed colors. Taking red and white stripes as an example, when the glue is pressed, the fibers of the red stripes will turn black and overflow into the white stripe area after being squeezed and subjected to high temperature, causing the white stripes to also turn black, which will seriously affect the quality of the produced zippers. In view of the above-mentioned problems, the inventor of this case conducted an in-depth study on the problem, which led to the creation of this case. [Summary of the invention]

[0005] The technical problem to be solved by the present invention is to provide a glue-stamping edge sealing structure and a glue-stamping method for a multi-color mixed striped zipper, so as to solve the problem that the existing glue-stamping edge sealing structure easily causes the produced zippers to appear black or have color bleeding, thereby seriously affecting the quality of the produced zippers.

[0006] The present invention is achieved in that:

[0007] In a first aspect, a glue-sealed edge structure of a multi-color mixed striped zipper includes a pair of zipper tapes and a tape attached to the end surface of the zipper tapes; the zipper tapes are provided with at least a first color-woven striped area and a second color-woven striped area along the length direction, the first color-woven striped area and the second color-woven striped area are adjacent to each other and have different colors;

[0008] The adhesive tape is pressed with a first twill pattern area at positions corresponding to the first color-woven stripe area and the second color-woven stripe area, the first twill pattern area completely covers the adhesive tape along the length direction of the zipper tape, and the width of the first twill pattern area along the width direction of the zipper tape is greater than the total width of the first color-woven stripe area and the second color-woven stripe area; the adhesive tape is pressed with a second twill pattern area on both sides of the first twill pattern area along the width direction of the zipper tape, and the pattern depth of the second twill pattern area is greater than the pattern depth of the first twill pattern area.

[0009] Furthermore, a pair of the zipper tapes are both sewn with chain teeth along the length direction on the opposite sides, and the area covered by the adhesive tape is not provided with chain teeth;

[0010] The two zipper tapes are each provided with at least a first color-woven stripe area and a second color-woven stripe area at positions adjacent to the chain elements; both sides of the first twill pattern area extend along the width direction of the zipper tape to outside the two color-woven stripe areas on the two zipper tapes that are farthest apart.

[0011] Furthermore, the pattern depth of the first twill pattern area is 0.06 mm to 0.08 mm shallower than the pattern depth of the second twill pattern area.

[0012] Furthermore, the first color-woven striped area and the second color-woven striped area on the two zipper tapes are symmetrically distributed along the horizontal center line of the entire multi-color mixed striped zipper, and the colors of the zipper tape, the first color-woven striped area and the second color-woven striped area are different.

[0013] Furthermore, the width of the first twill pattern area along the width direction of the zipper tape is 0.8 mm to 1.2 mm greater than the farthest distance between the two most distant yarn-dyed striped areas on the two zipper tapes;

[0014] The maximum distance between the two most distant color-woven striped areas on the two zipper tapes is less than or equal to half of the width of the entire multi-color mixed striped zipper.

[0015] Furthermore, the tape is pressed with a straight grid edge seal on the edge except the first twill pattern area, and the straight grid edge seal is arranged adjacent to the second twill pattern area; the tape is pressed with an independent square edge seal at the four corners; the middle part of the tape is pressed with a straight square edge seal for setting the zipper cutting line along the width direction of the zipper tape.

[0016] Furthermore, the pattern depths of the straight grid edge banding and the second twill pattern area are 0.21 mm to 0.23 mm, the depth of the independent square edge banding is 0.04 to 0.06 mm deeper than the straight grid edge banding, and the depth of the straight square edge banding is equal to the pattern depth of the first twill pattern area.

[0017] Furthermore, an opening for installing a square pin seat and a latch is provided in the middle of the adhesive tape along the length direction of the zipper tape.

[0018] Furthermore, the adhesive tape is a matte adhesive tape.

[0019] In a second aspect, a method for laminating a laminating edge sealing structure of a multi-color mixed striped zipper is provided, the method comprising the following steps:

[0020] A glue-stamping pattern mold is produced according to the pattern requirements of the glue-stamping edge sealing structure of the multi-color mixed striped zipper;

[0021] The edge-sealed portion of the zipper tape of the multi-color mixed striped zipper is conveyed between the glue pressing pattern mold and the ultrasonic welding head, and the adhesive tape is conveyed to the front and back sides of the edge-sealed portion of the zipper tape;

[0022] The glue pressing pattern mold and the ultrasonic welding head are controlled to clamp the zipper tape and the front and back tapes, and the ultrasonic welding head is controlled to weld the front and back tapes to the zipper tape, and the front tape is formed into the desired pattern under the action of the glue pressing pattern mold.

[0023] By adopting the technical solution of the present invention, at least the following beneficial effects are achieved:

[0024] 1. A first twill pattern area is pressed at a position corresponding to the first color-woven stripe area and the second color-woven stripe area, and the first twill pattern area spans the tape along the length direction of the zipper tape, and the width of the first twill pattern area along the width direction of the zipper tape is greater than the total width of the first color-woven stripe area and the second color-woven stripe area. Because the extrusion area of ​​the twill pattern is smaller than that of the straight grain, the first color-woven stripe area and the second color-woven stripe area of ​​the zipper tape can be less squeezed over a large area during the glue sealing process, thereby helping to reduce the blackening or fiber color bleeding of the first color-woven stripe area and the second color-woven stripe area during the glue sealing process.

[0025] 2. A second twill pattern area is pressed on both sides of the first twill pattern area, and the pattern depth of the first twill pattern area is deeper than that of the second twill pattern areas on both sides, that is, the first twill pattern area also adopts an air avoidance design, so that when the glue is pressed and sealed, the pressure on the first color-woven stripe area and the second color-woven stripe area of ​​the zipper tape is reduced, that is, the pressure on the first color-woven stripe area and the second color-woven stripe area will be less than the pressure at other positions, the first color-woven stripe area and the second color-woven stripe area will not be deeply squeezed, and combined with the small area of ​​the squeezed area of ​​the twill pattern, this can effectively avoid the first color-woven stripe area and the second color-woven stripe area from turning black or having fiber color bleeding during the glue pressing and sealing process, thereby ensuring the quality of the produced zipper.

[0026] 3. The pattern depth of the first twill pattern area is cleverly designed to be 0.06mm to 0.08mm shallower than that of the second twill pattern area. This not only ensures the firmness of the tape's fit, but also ensures that the multi-color mixed striped zippers produced can pass the test after washing and high-temperature steaming. In addition, the pattern depth of the first twill pattern area is 0.06mm to 0.08mm less than that of the second twill pattern area, which can effectively reduce the deep extrusion of the first color-woven stripe area and the second color-woven stripe area during edge sealing, thereby avoiding blackening or fiber color bleeding in the first color-woven stripe area and the second color-woven stripe area.

[0041] Embodiment 1

[0042] like Figure 2 As shown, the glue-pressed patterns of the existing zippers all use straight-grained edge-sealed patterns 300 with four fully sealed edges. When the glue-pressed patterns are used to produce the multi-color mixed striped zipper 200, the extrusion area of ​​the straight-grained edge-sealed patterns 300 is large and the extrusion depth is also deep, so that the yarn-dyed stripes on the multi-color mixed striped zipper 200 are easily blackened and overflow to other areas after being extruded and subjected to high temperature, resulting in the multi-color mixed striped zipper 200 being blackened or having fiber color bleeding, which seriously affects the quality of the multi-color mixed striped zipper 200. The technical solution of the present invention is specifically proposed to solve the problem that the existing glue-pressed patterns cause the multi-color mixed striped zipper 200 to be blackened or have fiber color bleeding. Please refer to the following introduction for the detailed technical solution.

[0043] See also Figure 1As shown, the present invention is a glue-pressed edge-sealing structure 100 of a multi-color mixed striped zipper 200, wherein the glue-pressed edge-sealing structure 100 comprises a pair of zipper tapes 1 and an adhesive tape 2 fitted on the end surface of the zipper tape 1. By pressing the adhesive tape 2 on the end of the zipper tape 1, the strength of the end of the zipper tape 1 can be effectively improved, ensuring that the end of the zipper tape 1 is not easily damaged during use; in the specific implementation of the present invention, an ultrasonic welding device can be used to achieve hot-melt welding of the adhesive tape 2 on the end surface of the zipper tape 1, and the adhesive tape 2 needs to be fitted on both the front and back sides of the end of the zipper tape 1, wherein the adhesive tape 2 on the front side is pressed with a pattern, and the adhesive tape on the back side can be combined with the zipper tape 1 by hot-melt flat pasting, and of course, the pattern can also be pressed according to actual needs;

[0044] The zipper tape 1 is provided with at least a first color-woven stripe area 11 and a second color-woven stripe area 12 along the length direction, wherein the first color-woven stripe area 11 and the second color-woven stripe area 12 are arranged adjacent to each other and have different colors, so as to achieve a multi-color mixing effect, making the entire multi-color mixing stripe zipper more beautiful;

[0045] The adhesive tape 2 is pressed with a first twill pattern area 21 at positions corresponding to the first color-woven stripe area 11 and the second color-woven stripe area 12, and the first twill pattern area 21 completely covers the adhesive tape 2 along the length direction of the zipper tape 1, that is, the first twill pattern area 21 spans the adhesive tape 2 along the length direction of the zipper tape 1; the width of the first twill pattern area 21 along the width direction of the zipper tape 1 is greater than the total width of the first color-woven stripe area 11 and the second color-woven stripe area 12; the adhesive tape 2 is pressed with a second twill pattern area 22 on both sides of the first twill pattern area 21 along the width direction of the zipper tape 1, and the pattern depth of the second twill pattern area 22 is greater than the pattern depth of the first twill pattern area 21.

[0046] By adopting the above technical solution of the present invention, at least the following beneficial effects are achieved:

[0047] 1. A first twill pattern area 21 is pressed at positions corresponding to the first color-woven stripe area 11 and the second color-woven stripe area 12, and the first twill pattern area 21 crosses the tape 2 along the length direction of the zipper tape 1. The width of the first twill pattern area 21 along the width direction of the zipper tape 1 is greater than the total width of the first color-woven stripe area 11 and the second color-woven stripe area 12. Since the extrusion area of ​​the twill pattern is smaller than that of the straight grain, the first color-woven stripe area 11 and the second color-woven stripe area 12 of the zipper tape 1 can be less squeezed over a large area during the gluing and edge sealing, thereby helping to reduce the blackening or fiber color bleeding of the first color-woven stripe area 11 and the second color-woven stripe area 12 during the gluing and edge sealing process.

[0048] 2. A second twill pattern area 22 is pressed on both sides of the first twill pattern area 21, and the pattern depth of the first twill pattern area 21 is deeper than that of the second twill pattern areas 22 on both sides, that is, the first twill pattern area 21 also adopts an air avoidance design, so that during the glue edge sealing, the pressure on the first color-woven stripe area 11 and the second color-woven stripe area 12 of the zipper tape 1 is reduced, that is, the pressure on the first color-woven stripe area 11 and the second color-woven stripe area 12 will be less than the pressure at other positions, and the first color-woven stripe area 11 and the second color-woven stripe area 12 will not be deeply squeezed. Combined with the small area of ​​the squeezed area of ​​the twill pattern, this can effectively avoid the first color-woven stripe area 11 and the second color-woven stripe area 12 from turning black or having fiber color bleeding during the glue edge sealing process, thereby ensuring the quality of the produced zipper.

[0049] In some embodiments of the present invention, a pair of the zipper tapes 1 are both sewn with chain teeth 3 along the length direction on the opposite sides, and the area covered by the adhesive tape 2 is not provided with chain teeth, that is, the area with the hot-melt adhesive tape 2 is used for installing a square pin seat, a latch pin, etc., so there is no need to provide chain teeth; when the present invention is implemented, the chain teeth 3 can be sewn on the edges of the opposite sides of the two zipper tapes 1 through the center line 41 and the stitching line 42 to ensure that the chain teeth 3 can be reliably combined with the edge of the zipper tape 1;

[0050] The two zipper tapes 1 are each provided with at least one first color-woven stripe area 11 and one second color-woven stripe area 12 at a position adjacent to the chain element 3; the two sides of the first twill pattern area 21 respectively extend along the width direction of the zipper tape 1 to outside the two color-woven stripe areas on the two zipper tapes 1 that are farthest apart, that is, all the color-woven stripe areas on the two zipper tapes 1 are within the area range of the first twill pattern area 21 in the width direction of the zipper tape 1, so as to ensure that all the color-woven stripe areas on the two zipper tapes 1 will not turn black or have fiber color bleeding during the glue sealing process.

[0051] In some embodiments of the present invention, the pattern depth of the first twill pattern area 21 is 0.06 mm to 0.08 mm shallower than the pattern depth of the second twill pattern area 22 .

[0052] The end surface of the zipper tape 1 is sealed with glue to improve the strength of the end of the zipper tape 1, so as to ensure that the multi-color mixed striped zipper 200 produced is not easy to be damaged. Therefore, if the pattern depth of the first twill pattern area 21 is too shallow, the strength of the first twill pattern area 21 will be insufficient. To this end, the present invention cleverly designs the pattern depth of the first twill pattern area 21 to be 0.06mm-0.08mm shallower than the pattern depth of the second twill pattern area 22, which can not only ensure the glue The fitting firmness of the belt 2 ensures that the multi-color mixed striped zipper 200 produced can pass the test after washing and high-temperature steaming, and the pattern depth of the first twill pattern area 21 is 0.06mm~0.08mm less than that of the second twill pattern area 22, which can effectively reduce the deep squeezing of the first color-woven striped area 11 and the second color-woven striped area 12 during the glue sealing, thereby avoiding the blackening or fiber color bleeding of the first color-woven striped area 11 and the second color-woven striped area 12.

[0053] As a specific embodiment of the present invention, the pattern depth of the first twill pattern area 21 is 0.07 mm shallower than the pattern depth of the second twill pattern area 22 .

[0054] In some embodiments of the present invention, in order to make the produced multi-color mixed striped zipper 200 more beautiful, the first color-woven striped area 11 and the second color-woven striped area 12 on the two zipper tapes 1 are symmetrically distributed along the horizontal center line of the entire multi-color mixed striped zipper 200, and the colors of the zipper tape 1, the first color-woven striped area 11 and the second color-woven striped area 12 are different. Of course, the above is only a specific embodiment of the present invention, but the present invention is not limited to this. In specific implementation, the first color-woven striped area 11 and the second color-woven striped area 12 on the two zipper tapes 1 can also be asymmetrically arranged. At the same time, on the two zipper tapes 1, in addition to the first color-woven striped area 11 and the second color-woven striped area 12, other color-woven striped areas can also be arranged, and each color-woven striped area can also be set to one or more.

[0055] In some embodiments of the present invention, the width of the first twill pattern area 21 along the width direction of the zipper tape 1 is 0.8mm to 1.2mm larger than the farthest distance between the two color-woven striped areas on the zipper tapes 1, so as to ensure that the deep extrusion of the first color-woven striped area 11 and the second color-woven striped area 12 can be further reduced during the glue sealing, so as to prevent blackening or fiber color bleeding during the glue sealing.

[0056] As a specific embodiment of the present invention, the maximum distance between the two most distant color-woven striped areas on the two zipper tapes 1 is less than or equal to one half of the width of the entire multi-color mixed striped zipper 200 .

[0057] Since the pattern depth of the first twill pattern area 21 is shallower than that of the second twill pattern area 22, if the maximum distance between the two most distant color-woven striped areas on the two zipper tapes 1 is too large, the first twill pattern area 21 will be too large. Therefore, the present invention can avoid the first twill pattern area 21 from being too large by designing the maximum distance between the two most distant color-woven striped areas on the two zipper tapes 1 to be less than or equal to half of the width of the entire multi-color mixed striped zipper 200, thereby further improving the adhesion firmness of the tape 2.

[0058] In some embodiments of the present invention, the edges of the tape 2 except the first twill pattern area 21 are pressed with straight grid edge sealing 23 to enhance the peeling strength of the tape 2 after the glue-sealed edge sealing, and the straight grid edge sealing 23 is arranged adjacent to the second twill pattern area 22; the tape 2 is pressed with an independent square edge sealing 24 at the four corners, because the four corners of the tape 2 are the positions most likely to fall off, and by arranging independent square edge sealing 24 at the four corners of the tape 2, the bonding firmness of the four corners of the tape 2 after glue-sealing can be ensured; the middle part of the tape 2 is pressed with a straight square edge sealing 25 for setting a zipper cutting line along the width direction of the zipper tape 1, so as to facilitate the cutting of the multi-color mixed striped zipper 200 along the zipper cutting line, and ensure that the edge of the tape 2 can be firmly bonded to the zipper tape 1 after cutting.

[0059] The present invention has straight grid edge sealing 23 pressed on the edges except the first twill pattern area 21, independent square edge sealing 24 pressed on the four corners of the tape 2, and a straight square edge sealing 25 for setting the zipper cutting line pressed on the middle of the tape 2, so that in specific implementation, it can not only effectively prevent blackening or fiber color bleeding during the glue pressing edge sealing, but also ensure the firmness of the entire tape 2.

[0060] In some embodiments of the present invention, in order to ensure that the adhesive tape 2 can be more reliably combined with the zipper tape 1 after the glue-pressing edge sealing, and to improve the service life of the multi-color mixed striped zipper 200, the pattern depth of the straight grid edge sealing 23 and the second twill pattern area 22 is 0.21mm-0.23mm, the depth of the independent square edge sealing 24 is 0.04-0.06mm deeper than the straight grid edge sealing 23, and the depth of the straight square edge sealing 25 is equal to the pattern depth of the first twill pattern area 21. Of course, because the area occupied by the straight square edge sealing 25 in the first twill pattern area 21 is small, and the straight square edge sealing 25 is located in the middle of the adhesive tape 2, the first color-woven stripe area 11 and the second color-woven stripe area 12 will not be greatly affected during the glue-pressing, so the depth of the straight square edge sealing 25 can also be equal to the pattern depth of the second twill pattern area 22.

[0061] As a specific implementation of the present invention, the pattern depths of the straight grid edge banding 23 and the second twill pattern area 22 are 0.22 mm, and the depth of the independent square grid edge banding 24 is 0.05 mm deeper than the straight grid edge banding 23 .

[0062] In some embodiments of the present invention, in order to install the square pin seat and the plug on the multi-color mixed striped zipper 200, an opening 5 for installing the square pin seat and the plug is opened in the middle of the tape 2 along the length direction of the zipper tape 1.

[0063] As a specific implementation of the present invention, the adhesive tape 2 is a matte adhesive tape.

[0064] The technical solution of the present invention is further described in detail below through a specific example:

[0065] As shown in the figure, a red color-woven striped area is provided on the two zipper tapes 1 of the multi-color mixed striped zipper 200 at a position close to the chain teeth 3, and the width of the red color-woven striped area is A. A white color-woven striped area is provided on the two zipper tapes 1 at a position close to the red color-woven striped area, and the width of the white color-woven striped area is B. The red color-woven striped area and the white color-woven striped area on the two zipper tapes 1 are symmetrically distributed along the horizontal center line; the maximum distance between the two farthest white color-woven striped areas on the two zipper tapes 1 is C, and the width of the first twill pattern area 21 is D, wherein D=C+1mm, that is, the width D of the first twill pattern area 21 along the width direction of the zipper tape 1 is 1mm larger than the maximum distance C between the two farthest white color-woven striped areas on the two zipper tapes 1, and the maximum distance C between the two farthest white color-woven striped areas on the two zipper tapes 1 is equal to half of the width of the entire multi-color mixed striped zipper 200.

[0066] Embodiment 2

[0067] See also Figure 1 As shown, the present invention provides a method for laminating a pressed glue edge sealing structure 100 of a multi-color mixed striped zipper 200, wherein the specific structure of the pressed glue edge sealing structure 100 of the multi-color mixed striped zipper 200 and the technical effects that can be obtained are exactly the same as those in Example 1. Please refer to the detailed introduction of Example 1 for details, and will not be repeated here.

[0068] The glue pressing method comprises the following steps:

[0069] Step S1, producing a glue pressing pattern mold according to the pattern requirements of the glue pressing edge sealing structure 100 of the multi-color mixed striped zipper 200, specifically, producing a glue pressing pattern mold for forming a first twill pattern area 21, a second twill pattern area 22, a straight grid edge sealing 23, an independent square edge sealing 24 and a straight square edge sealing 25 during glue pressing edge sealing;

[0070] Step S2, conveying the edge-sealed portion of the zipper tape 1 of the multi-color mixed striped zipper 200 between the glue pressing pattern mold and the ultrasonic welding head, and conveying the adhesive tape 2 to the front and back sides of the edge-sealed portion of the zipper tape 1. In the specific implementation of the present invention, the adhesive tape 2 can be conveyed to the front and back sides of the zipper tape 1 from both sides along a direction perpendicular to the conveying direction of the zipper tape 1;

[0071] Step S3, control the glue pattern die and the ultrasonic welding head to clamp the zipper tape 1 and the front and back tapes 2, and control the ultrasonic welding head to weld the front and back tapes 2 to the zipper tape 1, and make the front tape 2 form the desired pattern under the action of the glue pattern die, including the patterns of the first twill pattern area 21, the second twill pattern area 22, the straight grid edge banding 23, the independent square edge banding 24 and the straight square edge banding 25. At the same time, after completing the glue edge banding operation of the zipper tape 1 of the multi-color mixed striped zipper 200, control the glue pattern die and the ultrasonic welding head to leave the zipper tape 1, and convey the zipper tape 1 of the multi-color mixed striped zipper 200 forward to prepare for the glue edge banding operation of the next edge banding portion.
