Description

Technical Field

[0001] This utility model relates to a device for attaching elastic bands. Background Technology

[0002] In garment manufacturing, it is usually necessary to attach elastic bands to the waistband of trousers. Single-layer elastic bands are relatively easy to attach; however, if... Figure 1 The process shown, which involves first overlapping the elastic bands, then placing the fabric inside, and finally sewing them together with a sewing machine, is quite difficult and requires a skilled worker. Utility Model Content

[0003] To overcome the above-mentioned defects, the purpose of this utility model is to provide a device for attaching elastic bands.

[0004] To achieve the above objectives, the elastic band attaching device of this utility model includes a base plate, which is fixed to the table surface by bolts;

[0005] A Z-shaped hem structure is integrally formed on one side of the base plate. The inner side of the inverted V-shaped part of the Z-shaped hem structure is the area for placing the cut pieces, and the outer side of the inverted V-shaped part is the area for placing the elastic band. The outer contour of the inverted V-shaped part of the Z-shaped hem structure is adapted to the width of the elastic band.

[0006] A baffle is provided on the bottom plate on one side of the Z-shaped folded edge structure;

[0007] An adjustment device is provided on the base plate; the adjustment device includes a fixing block fixedly mounted on the base plate, and two through holes are provided on the fixing block facing the Z-shaped folded edge structure; a sliding rod is provided on the baffle corresponding to the two through holes, and the sliding rod is slidably mounted in the through holes; a tightening bolt is provided on the fixing block corresponding to the through holes.

[0008] During the sewing process, place the cut piece in the designated area and the elastic band on the outside of the inverted V-shaped section. Keep the edge of the cut piece against the inside of the inverted V-shaped section of the Z-shaped fold structure, and align the elastic band with the outside of the inverted V-shaped section. This ensures that the cut piece and elastic band can be precisely sewn together, thereby improving the quality and appearance of the final sewn product. Attached Figure Description

[0012] Figure 4 for Figure 3 Side view. Detailed Implementation

[0013] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0014] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0015] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] As shown in the figure, the device of this utility model is installed on the sewing equipment table 1. After installation, it is located in front of the sewing machine needle, that is, the feeding end of the sewing machine.

[0018] The device of this utility model includes a base plate 2, which is fixed to the table surface by bolts to ensure that it will not shift during the sewing process, thereby ensuring the accuracy and stability of the sewing work.

[0019] A Z-shaped folded edge structure is integrally formed on one side of the base plate, such as... Figure 3 As shown, in the Z-shaped hem structure, the inner side of the inverted V-shaped section is the area for placing the cut pieces 5, and the outer side of the inverted V-shaped section is the area for placing the elastic band 6. The width of the elastic band is approximately equal to the outer contour of the inverted V-shaped section of the Z-shaped hem structure.

[0020] During the sewing process, place the cut piece in the cut piece placement area 5, and place the elastic band on the outside of the inverted V-shaped part, keeping the edge of the cut piece against the inside of the inverted V-shaped part of the Z-shaped fold structure. Align the elastic band with the outside of the inverted V-shaped part to ensure that the cut piece is accurately sewn with the elastic band and other parts, thus ensuring the quality and appearance of the final sewn product.

[0021] Because elastic bands are soft and elastic, to ensure that the elastic bands are sewn along a predetermined path and position when the sewing equipment is running, and to avoid problems such as improper positioning of the elastic bands, a baffle 4 is suspended above the base plate on one side of the Z-shaped folding structure. Simultaneously, an adjustment device 3 is provided on the base plate. The adjustment device 3 includes a fixing block fixedly mounted on the base plate, with two through holes on the fixing block facing the Z-shaped folding structure. A sliding rod is provided on the baffle corresponding to the two through holes, and the sliding rod is slidably positioned within the through holes. A tightening bolt is provided on the fixing block corresponding to the through holes for adjusting the baffle and the Z-shaped folding structure. This allows the gap between the baffle and the Z-shaped folding structure to be adjusted according to the thickness of the elastic band.

[0022] The present invention has been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above-described embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Many other changes and modifications made without departing from the concept and scope of the present invention should be considered within the protection scope of the present invention.

[0023] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0024] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
