Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of zipper production equipment, and more specifically, to a flexible fixing structure for a cutter. Furthermore, this utility model also relates to a zipper adhesive applicator including the aforementioned flexible fixing structure for the cutter. Additionally, this utility model also relates to a zipper machine including the aforementioned zipper adhesive applicator. Background Technology
[0002] Zippers, as a common connector, are widely used in clothing, bags, and other fields. Depending on the material, zippers can be divided into nylon zippers, plastic zippers, and metal zippers. In the production of open zippers, "adhesive application" (also known as "fabric application") is a crucial step. The main purpose of adhesive application is to enhance the rigidity of the fabric strip, firstly to facilitate the connection of the square pin, and secondly to make it easier to insert the pin into the square when wearing clothing, thus enabling the zipper to open and close.
[0003] After the adhesive is applied, it needs to be cut. Currently, a cutter is installed on the upper mold. The cutter is cut by moving the upper mold relative to the cutter seat. The upper mold needs to be close to the cutter seat to achieve a good cutting effect. However, since the upper mold moves in a fixed position, its rigidity is slightly poor. Furthermore, it is difficult to ensure that the upper mold moves completely parallel to the cutter seat due to the precision of the parts. This causes the cutter to be subjected to reverse pressure when it is close to the cutter seat, resulting in blade biting during production. This shortens the cutter's life and increases equipment maintenance costs.
[0004] In conclusion, how to reduce cutter damage to extend its service life is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0005] In view of this, the purpose of this utility model is to provide a flexible fixing structure for the cutter, which enables the cutter to have a flexible structure, avoids damage to the cutter when it moves due to rigid fixing, greatly improves the service life of the cutter, and reduces equipment maintenance costs.
[0006] Another objective of this invention is to provide a zipper applicator mechanism that includes a flexible fixing structure for the cutter.
[0007] Another objective of this invention is to provide a zipper machine that includes the aforementioned zipper adhesive applicator.
[0008] To achieve the above objectives, this utility model provides the following technical solution:
[0009] A flexible fixing structure for a cutter includes:
[0010] A glue holder, wherein one surface of the glue holder is a cut surface;
[0011] A movable component, located near the cutting surface and movable relative to the adhesive base;
[0012] The cutter includes a mounting part, a connecting part, and a cutting part. The cutter is mounted on the moving part through the mounting part. A preset gap is formed between the connecting part and the moving part. When the moving part moves relative to the rubber seat, the cutting part contacts and slides with the cutting surface.
[0013] Furthermore, the mounting part of this utility model has an L-shaped structure, and the movable part is provided with a mounting groove for fixing to the first end of the mounting part.
[0014] Furthermore, the mounting portion is provided with at least one through hole, and the movable part is provided with a mounting hole that mates with the through hole.
[0015] Furthermore, in this invention, the thickness of the connecting portion is less than the thickness of the second end of the mounting portion, so that a preset gap is formed between the connecting portion and the moving member.
[0016] Furthermore, in this invention, the cutting portion and the connecting portion form a preset angle, and the end of the cutting portion away from the connecting portion is parallel to the cutting surface.
[0017] Furthermore, in this invention, the moving member has a groove on its side wall near the cutting surface, and the groove has a bent portion similar in shape to the cutter on the side near the cutting part.
[0018] Furthermore, in this invention, at least one clamping member is installed on the blade groove, the clamping member is in contact with the cutting blade, and the clamping member is a non-metallic part with elastic deformation function.
[0019] Furthermore, in this invention, the clamping member is an Oxford bar, and the clamping member is located on the side of the movable member near the rubber base.
[0020] A zipper adhesive applicator, comprising the flexible fixing structure for the cutter as described in any one of the preceding claims, further comprising:
[0021] Upper mold base, the movable component is mounted on the upper mold base, and a pressing surface is provided at one end of the movable component near the glue seat;
[0022] A transducer, on which a welding head is mounted, wherein the welding head is fixed to the pressing surface by adhesive bonding and zipper fastening.
[0023] A zipper machine includes the aforementioned zipper adhesive applicator.
[0024] The flexible fixing structure for the cutter provided by this utility model involves both the adhesive base and the moving part being installed on a zipper machine. The adhesive base restricts the movement of the adhesive strip, while the moving part drives the cutter to move, allowing relative movement between the cutter and the adhesive base. One surface of the adhesive base is the cutting surface, and the moving part is located on one side of the cutting surface of the adhesive base. Therefore, when the cutter moves, the adhesive strip is cut by the shearing force between the cutter and the cutting surface. The cutter includes a mounting part, a connecting part, and a cutting part. The cutter is mounted on the moving part through the mounting part, and a preset gap is left between the connecting part and the moving part. When the moving part moves relative to the adhesive base, the cutting part slides against the cutting surface. In other words, by leaving a preset gap between the cutter and the side wall of the moving part, the cutter has deformable space. When the cutter moves close to the adhesive base, its own deformation protects the cutter from damage and extends the service life of the cutter.
[0025] This utility model also provides a zipper adhesive applicator including a flexible fixing structure for the cutter, which has the above-mentioned beneficial effects.
[0026] This utility model also provides a zipper machine including a zipper adhesive applicator, which has the above-mentioned beneficial effects. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0037] The core of this invention is to provide a flexible fixing structure for the cutter, which enables the cutter to have a flexible structure, avoiding damage to the cutter when it moves due to rigid fixing, greatly improving the service life of the cutter and reducing equipment maintenance costs.
[0038] Another core aspect of this invention is providing a zipper adhesive applicator mechanism that includes a flexible fixing structure for the cutter.
[0039] Another core aspect of this invention is to provide a zipper machine that includes the aforementioned zipper adhesive applicator.
[0040] Please refer to Figure 2 A flexible fixing structure for a cutter includes a rubber base 2, a movable member 1, and a cutter 3. One surface of the rubber base 2 is a cutting surface 201. The movable member 1 is located on one side of the cutting surface 201 of the rubber base 2 and is movable relative to the rubber base 2. The cutter 3 includes a mounting part 301, a connecting part 302, and a cutting part 303. The cutter 3 is mounted on the movable member 1 through the mounting part 301. A preset gap is formed between the connecting part 302 and the movable member 1. When the movable member 1 moves relative to the rubber base 2, the cutting part 303 contacts and slides with the cutting surface 201.
[0041] It should be noted that in this practical embodiment, both the adhesive base 2 and the moving part 1 are installed on the zipper machine, wherein the moving part 1 moves along the cutting surface 201 through a pneumatic structure or mechanical means.
[0042] In addition, in this practical embodiment, the adhesive base 2 is made of metal, and the cutting surface 201 is a smooth plane to improve the cutting effect.
[0043] Alternatively, in some embodiments, the cutter 3 can be fixed to the movable part 1 by means of bolts, welding, or other methods.
[0044] Alternatively, in some embodiments, the cutter 3 may be a spring-loaded blade or made of spring steel.
[0045] Optionally, in some embodiments, the preset gap between the connecting part 302 and the moving part 1 is 2mm, or other gaps are used, such as 1mm-5mm.
[0046] Optionally, in some embodiments, the mounting part 301, the connecting part 302, and the cutting part 303 of the cutter 3 are integral structures, that is, the cutter 3 is made in one piece.
[0047] In use, both the adhesive base 2 and the moving part 1 are mounted on the zipper machine. The adhesive base 2 restricts the movement of the adhesive strip, while the moving part 1 drives the cutter 3 to move, so that the cutter 3 and the adhesive base 2 move relative to each other. One side of the adhesive base 2 is the cutting surface 201, and the moving part 1 is located on one side of the cutting surface 201 of the adhesive base 2. Therefore, when the cutter 3 moves, the adhesive strip is cut by the shearing force between the cutter 3 and the cutting surface 201. The cutter 3 includes a mounting part 301, a connecting part 302, and a cutting part. 303, the cutter 3 is mounted on the movable part 1 through the mounting part 301. A preset gap is left between the connecting part 302 and the movable part 1. When the movable part 1 moves relative to the rubber seat 2, the cutting part 303 slides in contact with the cutting surface 201. That is, by leaving a preset gap between the cutter 3 and the side wall of the movable part 1, the cutter 3 has a deformable space. When the cutter 3 moves close to the rubber seat 2, it protects the cutter 3 from damage through its own deformation, thereby increasing the service life of the cutter 3.
[0048] Please refer to Figure 6 In some embodiments, the mounting part 301 has an L-shaped structure, and the moving part 1 is provided with a mounting groove 101 for fixing to the first end of the mounting part 301. That is, the cutter 3 is fixed by the cooperation between the mounting part 301 and the mounting groove 101. Specifically, the bent position of the mounting part 301 is inserted into the mounting groove 101 to achieve fixation.
[0049] Optionally, in some embodiments, the bent position of the mounting part 301 is fixed by an interference fit.
[0050] In other embodiments, the mounting part 301 is provided with a plurality of protrusions, and the moving part 1 is provided with slots that cooperate with the protrusions. When the protrusions are inserted into the slots, their cutters 3 are fixed.
[0051] In other embodiments, to further improve the fixing firmness of the cutter 3, the mounting part 301 is Z-shaped and is inserted into the moving part 1 by plugging. At the same time, a fixing part is provided on the moving part 1 to fix the insertion position of the mounting part 301, thereby achieving complete fixing of the cutter 3.
[0052] Please refer to Figure 4In some embodiments, the mounting part 301 is provided with at least one through hole 102, and the moving part 1 is provided with a mounting hole 304 that mates with the through hole 102. That is, the cutter 3 and the moving part 1 are fixed together by passing a bolt through the through hole 102 of the mounting part 301.
[0053] Optionally, in some embodiments, the mounting hole 304 is a threaded hole or a through hole 102.
[0054] Please refer to Figure 6 In some embodiments, the thickness of the connecting portion 302 is less than the thickness of the second end of the mounting portion 301, so that a preset gap is formed between the connecting portion 302 and the moving member 1. That is, the thickness of the connecting portion 302 of the cutter 3 is smaller, so that a gap is formed between the connecting portion 302 and the moving member 1, so that the cutter 3 has a preset deformation space.
[0055] Optionally, in some embodiments, the connection position between the connecting part 302 and the mounting part 301 is chamfered to improve connection stability.
[0056] In other embodiments, the movable member 1 is provided with a groove, and the connecting part 302 is located in the groove and does not contact the movable member 1. Therefore, the depth of the groove is the gap width.
[0057] Please refer to Figure 6 In some embodiments, the cutting portion 303 and the connecting portion 302 are at a preset angle, and the end of the cutting portion 303 away from the connecting portion 302 is parallel to the cutting surface 201. That is, by adopting a preset angle between the cutting portion 303 and the connecting portion 302, the cutting portion 303 extends a certain length beyond the connecting portion 302, and the end of the cutting portion 303 away from the connecting portion 302 is parallel to the cutting surface 201. In other words, the end of the cutting portion 303 that contacts the cutting surface 201 remains parallel to the cutting surface 201, thereby increasing the area of the cutting surface 201 and improving the cutting effect.
[0058] Optionally, in some embodiments, the cutting portion 303 and the connecting portion 302 are at an obtuse angle, which is beneficial to improving the strength of the cutter 3.
[0059] Please refer to Figure 4 In some embodiments, the moving member 1 has a groove 103 on its side wall near the cutting surface 201. The groove 103 has a bent portion similar in shape to the cutter 3 on the side near the cutting part 303. The groove 103 is provided on the moving member 1, and the bent portion is provided at the bottom of the groove 103, so that the shape of the entire groove 103 is similar to the shape of the cutter 3. When the cutter 3 is deformed, it can effectively support the cutter 3, further improving the stability of the cutter 3 during use.
[0060] Please refer to Figure 1To further enhance the support for the cutter 3, in some embodiments, at least one clamping member 4 is installed on the cutter groove 103. The clamping member 4 contacts the cutter 3 and is a non-metallic part with elastic deformation function. That is, at least one clamping member 4 in contact with the cutter 3 is fixed on the cutter groove 103. The clamping member 4 increases the stability of the cutter 3 during use and prevents the cutter 3 from vibrating. At the same time, the clamping member 4 is a non-metallic part with elastic deformation function. Through the elastic deformation function of the clamping member 4 material itself, there is an elastically deformable workpiece between it and the cutter 3. Therefore, it can also avoid hard contact between the cutter 3 and the rubber seat 2, effectively increasing the service life of the cutter 3.
[0061] Optionally, in some embodiments, the knife groove 103 is provided with a placement groove, and the clamping member 4 is inserted into the placement groove to fix the clamping member 4.
[0062] In the above embodiment, the clamping member 4 is inserted into the placement groove by interference fit.
[0063] Alternatively, in some embodiments, the clamping member 4 is an Oxford rod.
[0064] In other embodiments, the clamping member 4 may be made of materials such as rubber, silicone, or nylon.
[0065] Optionally, in some embodiments, the clamping member 4 is located on the side of the moving member 1 near the rubber seat 2. Specifically, the clamping member 4 is located on the side near the rubber seat 2, which can further improve the support of the cutter 3.
[0066] Optionally, in some embodiments, when one clamping member 4 is used, it is located at the center line of the cutter 3; when two or more clamping members 4 are used, they are evenly distributed along the width direction of the cutter 3.
[0067] A zipper adhesive applicator includes the flexible fixing structure of the cutter mentioned above, and also includes an upper mold base 5 and a transducer 6. The upper mold base 5 and the transducer 6 are installed on a zipper machine. A movable part 1 is installed on the upper mold base 5. The movable part 1 has a pressing surface at one end near the adhesive base 2. A welding head 7 is installed on the transducer 6. The welding head 7 and the pressing surface achieve adhesive application and zipper fixation. That is, through the pressing effect of the welding head 7 and the pressing surface, the transducer 6 works to achieve ultrasonic welding, so as to fix the adhesive to the zipper.
[0068] A zipper machine includes the aforementioned zipper adhesive applicator.
[0069] In other words, the key point of this utility model is that when the cutter 3 moves, the rubber strip is cut by the shearing force between the cutter 3 and the cutting surface 201. The cutter 3 includes a mounting part 301, a connecting part 302 and a cutting part 303. The cutter 3 is mounted on the moving part 1 through the mounting part 301. A preset gap is left between the connecting part 302 and the moving part 1. When the moving part 1 moves relative to the rubber seat 2, the cutting part 303 contacts and slides with the cutting surface 201. That is, by leaving a preset gap between the cutter 3 and the side wall of the moving part 1, the cutter 3 has a deformable space. When the cutter 3 moves close to the rubber seat 2, it protects the cutter 3 from damage through its own deformation, thereby increasing the service life of the cutter 3.
