Abstract
Description
Technical Field
[0001] This utility model relates to the field of bag manufacturing, and more specifically, to a zipper shaping fixture. Background Technology
[0002] A zipper consists of zipper teeth and fabric straps on both sides. During the production and processing of leather bags, the fabric straps on both sides of the zipper are sewn to the opening of the bag. The existing bag opening is U-shaped, and the corresponding zipper must also be U-shaped. Because zippers are flexible, it is difficult to control the position when sewing the zipper to the bag opening. The operation is extremely time-consuming and it is easy to cause the fabric straps on both sides to be misaligned with the bag opening, resulting in rework or even scrap. In order to quickly sew the zipper to the bag opening, it is necessary to pre-shape the zipper so that it is U-shaped before sewing. Therefore, there is an urgent need for a shaping fixture that can make the zipper U-shaped. Utility Model Content
[0003] This utility model provides a zipper shaping fixture, which aims to solve the problem of how to shape zippers into a U-shape.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a zipper shaping fixture, comprising a base and an insert plate, wherein the base has a U-shaped shaping notch, the insert plate is slidably inserted into the shaping notch, a locking block is movably provided on one side of the shaping notch, and pressure plates are provided on both ends of the base.
[0005] Furthermore, the pressure plate is provided with a protruding magnet, and the base has a groove in which a magnet is placed.
[0006] Furthermore, a platform is provided on one side of the base, and a push-pull clamp is provided on the platform. The push-pull clamp is connected to the locking block, and the shaping notch has a guide channel. The locking block is slidably placed in the guide channel.
[0007] Furthermore, a strip groove is formed along the inner side of the shaping notch, and clearance notches are formed on both sides of the opening of the shaping notch.
[0008] Furthermore, the pressure plate has a U-shaped pressure plate notch, and the area of the pressure plate notch is smaller than the area of the shaping notch.
[0009] Furthermore, one end of the pressure plate is hinged to both sides of the base.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] This utility model discloses a zipper shaping fixture with a simple and ingenious design. It includes a base and an insert plate. The base has a U-shaped shaping notch, into which the insert plate slidably inserts. A locking block is movably mounted on one side of the shaping notch, and pressure plates are mounted on both ends of the base. In use, the insert plate first presses the zipper teeth against the inner wall of the shaping notch, and the locking block holds the insert plate in place. Then, the pressure plates are lowered to press the fabric strip on both sides of the zipper teeth against the insert plate. Finally, the base is heated to shape the zipper. After shaping, the locking block is moved, and the insert plate is removed, thus achieving the U-shaped shaping of the zipper. The cooperation between the insert plate and the shaping notch quickly fixes the zipper teeth into a U-shape, and the pressure plates flatten the fabric strip. The operation is simple and convenient, improving practicality. Attached Figure Description

[0022] Example
[0023] Reference Figure 1-3As shown, this utility model discloses a zipper shaping fixture, including a base 10 and an insert plate 20. The base 10 has a U-shaped shaping notch 101. The insert plate 20 is slidably inserted into the shaping notch 101, pressing the zipper teeth against the three sides of the insert plate 20. The insert plate 20 is then inserted into the shaping notch 101, pressing the zipper teeth against the inner wall of the shaping notch 101. Furthermore, a strip groove 1011 is formed along the inner side of the shaping notch 101, and clearance notches 1012 are formed on both sides of the opening of the shaping notch 101. The insert plate 20 presses the zipper teeth into the strip groove 1011, and the fabric strips on both sides of the tooth extend from both sides of the shaping notch 101. The clearance notches 1012 on both sides facilitate the removal of the insert plate 20 from the shaping notch 101.
[0024] Reference Figure 1-3 As shown, a locking block 102 is movably mounted on one side of the shaping notch 101 on the base 10. Specifically, a platform is provided on one side of the base 10, and a push-pull clamp 1021 is provided on the platform. The push-pull clamp 1021 is connected to the locking block 102. The shaping notch 101 has a guide channel, and the locking block 102 is slidably placed in the guide channel. When the insert plate 20 is inserted into the shaping notch 101, the push-pull clamp 1021 is pushed to move the locking block 102 from the guide channel into the shaping notch 101, pushing and pressing the insert plate 20 into the shaping notch 101, thereby fixing the insert plate 20. When it is necessary to remove the insert plate 20, the push-pull clamp 1021 is pushed to move the locking block 102 along the guide channel and exit from the shaping notch 101, so that the insert plate 20 can be removed.
[0025] Reference Figure 1-3 As shown, pressure plates 103 are provided on both ends of the base 10. Specifically, in this embodiment, the pressure plates 103 include two plates respectively provided on both ends of the base 10. One end of the pressure plate 103 is hinged to both sides of the base 10. The pressure plate 103 can be flipped to cover the base 10. The pressure plate 103 is provided with protruding magnets 1031. The base 10 has a groove, and the magnets 1031 are provided in the groove. When the insert plate 20 presses the zipper teeth at the shaping notch 101, the fabric tape extends from both sides of the shaping notch 101. The pressure plate 103 is closed and presses the fabric tape onto the insert plate 20. The magnets 1031 are used to make the pressure plate 103 stick to the base 10, and the fabric tape on both sides of the zipper is flattened on the insert plate 20. Finally, the base 10 is heated and shaped.
[0026] Furthermore, the pressure plate 103 has a U-shaped notch, the area of which is smaller than that of the shaping notch 101. After the pressure plate 103 is closed, the edge of the notch can press down on the fabric strip. The notch in the pressure plate 103 facilitates observation of the flattening of the fabric strip and reduces the overall weight.
[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
