Description

Technical Field

[0001] This utility model relates to the field of nylon zipper technology, and more specifically, it relates to an ultrasonic applicator for preventing nylon zipper teeth from sticking. Background Technology

[0002] Nylon zippers are zippers made from nylon monofilaments or polyester fibers. Their teeth are formed by winding around a central line through a heated mold. They are characterized by low cost, high production volume, and high popularity.

[0003] Currently, nylon zippers require adhesive tape to be applied to their surface. This process improves the zipper's water resistance, abrasion resistance, and overall performance. Ultrasonic adhesive application is typically used. The principle of ultrasonic adhesive application is to use the heat generated by high-frequency vibration to fuse the tape with the nylon zipper fabric in a short time, resulting in high bonding strength and effectively preventing the tape from becoming hard or brittle.

[0004] However, although ultrasonic adhesive application is convenient and quick, the zipper teeth may be affected by ultrasonic vibration during the process. Ultrasonic vibration can cause the suspended teeth to generate a large amplitude. In this case, the zipper teeth are affected by ultrasonic energy and overheat, which can cause the teeth to melt and stick together, affecting the subsequent use of the zipper. Therefore, an ultrasonic adhesive application machine for nylon zippers with anti-stick teeth is proposed to improve the existing problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an ultrasonic applicator for nylon zippers that prevents sticking to teeth.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An ultrasonic applicator for anti-sticking nylon zippers includes a drive assembly, an upper mold assembly located below the drive assembly, a zipper assembly located below the upper mold assembly, and a lower mold assembly located at the bottom of the zipper assembly.

[0008] The drive assembly includes a cylinder, a fixed frame is provided at the bottom of the cylinder, an output shaft is provided at the output end of the cylinder, two sets of support rods are symmetrically arranged at the bottom of the fixed frame, and a set of sleeves is provided on the outer side of each of the two sets of support rods.

[0009] The upper mold assembly includes a first mounting plate connected to the output shaft of the cylinder. The outer walls of the two sets of sleeves are respectively connected to the first mounting plate. An upper mold body is provided at the bottom of the first mounting plate. A fixing block is provided on one side of the upper mold body. A sliding groove is provided on one side of the fixing block. An auxiliary component is provided inside the sliding groove. A spring is provided on the top of the auxiliary component. The end of the spring away from the auxiliary component is fixedly connected to the top of the sliding groove.

[0010] By adopting the above technical solution, the sleeve can slide along the outer wall of the support rod. When the cylinder is started, the cylinder drives the first mounting plate to move in a straight line. At this time, the sleeve slides along the outer wall of the support rod, and the upper mold body moves in a straight line following the first mounting plate. Since the auxiliary part contacts the zipper assembly first, the auxiliary part can move in a straight line along the inside of the slide groove.

[0011] The present invention is further configured such that: the zipper assembly includes two sets of zipper bodies, the middle position of the two sets of zipper bodies is provided with chain teeth, and the middle of the top surface of the two sets of zipper bodies is provided with adhesive strips.

[0012] By adopting the above technical solution, the adhesive strip can contact the upper mold body during the adhesive application process. Under the action of the upper mold body and the lower mold assembly, the adhesive strip can be bonded to the two sets of zipper bodies, meeting the adhesive application requirements. In addition, during the adhesive application process, the fixing block descends in a straight line along with the upper mold body, and then the auxiliary part descends along with the fixing block. Since the length of the auxiliary part is longer than that of the upper mold body, the auxiliary part contacts the chain teeth first. When the upper mold body contacts the chain teeth, the auxiliary part has already pressed down on the chain teeth, and the spring connected to the auxiliary part is also compressed. After the chain teeth are pressed down, the positions of the chain teeth and the upper mold body are misaligned, reducing the influence of ultrasonic waves on the chain teeth during the adhesive application process and reducing the possibility of the chain teeth sticking together due to heat. After the adhesive application is completed, under the action of elastic potential energy, the spring rebounds, and the auxiliary part moves with the spring back to the initial position.

[0013] The present invention is further configured such that: the lower mold assembly includes a lower mold body, a placement groove is provided on one side of the lower mold body, and a second mounting plate is provided on the outer side of the lower mold body.

[0014] The present invention is further configured such that: the ends of the two sets of support rods away from the fixed frame are connected to the second mounting plate, and the bottom of the second mounting plate is provided with two sets of telescopic rods.

[0015] The present invention is further configured such that: a telescopic threaded rod is provided on the bottom of the second mounting plate on the side opposite to the two sets of telescopic rods, and a connecting plate is provided at the bottom of the two sets of telescopic rods.

[0016] The present invention is further configured such that: an ultrasonic wave chamber is provided at the bottom of the connecting plate, and the lower mold body passes through the connecting plate and is connected to the ultrasonic wave chamber.

[0017] By adopting the above technical solution, the cylinder is started, and the cylinder output shaft drives the first mounting plate to move linearly along the two sets of support rods. Under the drive of the first mounting plate, the upper mold body comes into contact with the adhesive strip, and the adhesive application of the zipper assembly is achieved under the action of the upper mold body and the lower mold body.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. By setting up a cylinder, the cylinder provides power for the movement of the upper mold body, realizing the linear movement of the upper mold body. At the same time, the combination of the fixed frame and the support rod can provide support for the cylinder, ensuring the operation of the entire device.

[0020] 2. By combining auxiliary components with springs, the chain teeth near the upper mold body can be pressed, creating a displacement difference between the chain teeth and the upper mold body, reducing the impact of ultrasonic waves on the chain teeth and lowering the possibility of the chain teeth sticking together.

[0021] 3. By setting up placement slots, the placement slots provide adjustable space for the chain teeth, reducing the possibility of the chain teeth breaking under pressure. Attached Figure Description

[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0035] Example 1, please refer to Figure 1-7 The present invention provides the following technical solution:

[0036] See Figure 1 An ultrasonic applicator for anti-sticking nylon zippers includes a drive assembly 1, an upper mold assembly 2 below the drive assembly 1, a zipper assembly 3 below the upper mold assembly 2, and a lower mold assembly 4 at the bottom of the zipper assembly 3. The zipper assembly 3 is pulled by a zipper traction machine through the middle position between the upper mold assembly 2 and the lower mold assembly 4, so that the upper mold assembly 2 and the lower mold assembly 4 can perform adhesive application on the zipper assembly 3.

[0037] See Figure 2 and Figure 3 The drive assembly 1 includes a cylinder 11, a fixed frame 12 is provided at the bottom of the cylinder 11, an output shaft is provided at the output end of the cylinder 11, and two sets of support rods 14 are symmetrically arranged at the bottom of the fixed frame 12. A set of sleeves 13 is provided on the outer side of each of the two sets of support rods 14, and the sleeves 13 can slide along the outer side wall of the support rods 14.

[0038] See Figures 2-6The upper mold assembly 2 includes a first mounting plate 21, which is connected to the output shaft of the cylinder 11. The outer walls of the two sets of sleeves 13 are respectively connected to the first mounting plate 21. The bottom of the first mounting plate 21 is provided with an upper mold body 22. A fixing block 23 is provided on one side of the upper mold body 22. A sliding groove is opened on one side of the fixing block 23. An auxiliary component 24 is provided inside the sliding groove. A spring 25 is provided on the top of the auxiliary component 24. The end of the spring 25 away from the auxiliary component 24 is fixedly connected to the top of the sliding groove. When the cylinder 11 is started, the cylinder 11 drives the first mounting plate 21 to move linearly. At this time, the sleeve 13 slides along the outer wall of the support rod 14, and the upper mold body 22 moves linearly with the first mounting plate 21. Since the auxiliary component 24 contacts the zipper assembly 3 first, the auxiliary component 24 can move linearly along the inside of the sliding groove.

[0039] By setting up cylinder 11, the cylinder 11 provides power for the movement of the upper mold body 22, realizing the linear movement of the upper mold body 22. At the same time, the combination of the fixed frame 12 and the support rod 14 can provide support for cylinder 11, ensuring the operation of the entire device.

[0040] See Figure 2 and Figure 4 The zipper assembly 3 includes two sets of zipper bodies 31. A chain tooth 32 is provided in the middle of the two sets of zipper bodies 31. An adhesive strip 33 is provided in the middle of the top surface of the two sets of zipper bodies 31. During the adhesive application process, the adhesive strip 33 can contact the upper mold body 22. Under the action of the upper mold body 22 and the lower mold assembly 4, the adhesive strip 33 can be adhered to the two sets of zipper bodies 31, thus meeting the adhesive application requirements.

[0041] See Figure 4 During the adhesive application process, the fixing block 23 descends in a straight line along with the upper mold body 22, and the auxiliary component 24 descends along with the fixing block 23. Since the length of the auxiliary component 24 is longer than that of the upper mold body 22, the auxiliary component 24 contacts the chain tooth 32 first. When the upper mold body 22 contacts the chain tooth 32, the auxiliary component 24 has already pressed down on the chain tooth 32, and the spring 25 connected to the auxiliary component 24 is also compressed. After the chain tooth 32 is pressed down, the chain tooth 32 and the upper mold body 22 are misaligned, which reduces the influence of ultrasonic waves on the chain tooth 32 during the adhesive application process and reduces the possibility of the chain tooth 32 sticking together due to heat. When the adhesive application is completed, under the action of elastic potential energy, the spring 25 rebounds, and the auxiliary component 24 moves with the spring 25 and returns to its initial position.

[0042] By combining the auxiliary component 24 with the spring 25, the chain teeth 32 near the upper mold body 22 can be pressed, causing a displacement difference between the chain teeth 32 and the upper mold body 22, reducing the impact of ultrasonic waves on the chain teeth 32, and reducing the possibility of the chain teeth 32 sticking together.

[0043] See Figures 2-7The lower mold assembly 4 includes a lower mold body 41. A placement groove 46 is provided on one side of the lower mold body 41. A second mounting plate 42 is provided on the outer side of the lower mold body 41. A zipper assembly 3 is placed on the top of the lower mold body 41. The lower mold body 41 provides a placement space for the zipper assembly 3 and facilitates the application of adhesive to the zipper assembly 3 by the lower mold body 41 and the upper mold body 22. At the same time, the placement groove 46 provides adjustable space for the chain teeth 32, reducing the possibility of the chain teeth 32 breaking under pressure.

[0044] See Figures 2-7 The ends of the two sets of sleeves 13 away from the fixed frame 12 are connected to the second mounting plate 42, and the bottom of the second mounting plate 42 is provided with two sets of telescopic rods 43.

[0045] See Figures 2-7 A telescopic threaded rod 47 is provided on the bottom side of the second mounting plate 42 opposite to the two sets of telescopic rods 43. A connecting plate 44 is provided at the bottom of the two sets of telescopic rods 43. First, by adjusting the telescopic threaded rod 47, the position between the connecting plate 44 and the second mounting plate 42 is determined, and then the position of the lower mold body 41 exposed above the top of the second mounting plate 42 is determined. At this time, the cylinder 11 is started, and the output shaft of the cylinder 11 drives the first mounting plate 21 to move linearly along the two sets of support rods 14. Under the drive of the first mounting plate 21, the upper mold body 22 contacts the adhesive strip 33. Under the action of the upper mold body 22 and the lower mold body 41, the adhesive application of the zipper assembly 3 is achieved. During the adhesive application process, the auxiliary part 24 and the spring 25 cooperate to press the chain teeth 32. The placement groove 46 provides adjustable space for the downward pressing of the chain teeth 32.

[0046] By setting the upper mold body 22 and the lower mold body 41 to work together, the zipper assembly 3 can be glued. During the glue application process, the auxiliary part 24 can press the chain teeth 32. At this time, the placement groove 46 provides the chain teeth 32 with an adjustable space position when pressed down, reducing the possibility of the chain teeth 32 breaking under the pressing condition.

[0047] See Figures 2-7 An ultrasonic wave box 45 is provided at the bottom of the connecting plate 44. The lower mold body 41 passes through the connecting plate 44 and is connected to the ultrasonic wave box 45. The ultrasonic wave box 45 enables the upper mold body 22 and the lower mold body 41 to cooperate in attaching the adhesive strip 33 to the top of the two sets of zipper bodies 31.

[0048] Specifically, firstly, by adjusting the telescopic threaded rod 47, the position between the connecting plate 44 and the second mounting plate 42 is determined, thereby determining the position where the lower mold body 41 protrudes from the top of the second mounting plate 42. At this time, the cylinder 11 is started, and the output shaft of the cylinder 11 drives the first mounting plate 21 to move linearly along the two sets of sleeves 13. Driven by the first mounting plate 21, the upper mold body 22 comes into contact with the adhesive strip 33. The ultrasonic wave box 45 makes the upper mold body 22 and the lower mold body 41 cooperate to stick the adhesive strip 33 to the top of the two sets of zipper bodies 31. After the adhesive application is completed, the cylinder 11 is started to run in the opposite direction. The upper mold body 22 moves away from the adhesive strip 33 under the drive of the cylinder 11, and the zipper assembly 3 moves its position under the drive of the zipper traction machine. The cylinder 11 is started again, which can realize the upper mold body 22 and the lower mold body 41 to apply adhesive to the zipper assembly 3 again.

[0049] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
