Technical Field

[0001] This utility model belongs to the technical field of sewing machine sewing accessories, specifically relating to a device for sewing zippers and binding edges in one step. Background Technology

[0002] Zippers are widely used in the clothing and bag industries. For example, when a zipper is sewn onto a garment placket, the edges of the placket need to be bound with piping before the zipper is sewn onto it. In traditional manufacturing processes, binding and sewing the zipper are done in two separate steps. Binding requires one stitching step, and sewing the zipper requires another. Because it is very difficult to ensure that the stitches align perfectly during these two steps, the deviation rate is high. High-end garments have very strict stitching requirements, which affects the appearance of the stitching and leads to a high rework rate. Furthermore, separating the sewing process into two steps significantly reduces work efficiency.

[0003] In view of this, this case arises. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0032] This utility model is an improvement made to address the shortcomings of the current system where the edge-binding process for fabric and the zipper sewing process are completed independently.

[0033] Please see Figure 1 and Figure 2 As shown, the zipper sewing and binding one-time forming device includes a binding channel 3, a fabric channel 1 connected to the binding channel 3 and set below the binding channel 3, a zipper channel 2 set above the binding channel 3, and the binding channel 3 standing upright on the fabric channel 1. This forming device is installed on the sewing machine panel to simultaneously sew zippers and binding fabric, combining the two processes into one.

[0034] like Figure 2 As shown, the zipper channel 2 consists of a base plate, a cover plate that is movably fitted onto the base plate, and a movable bracket 9 that mounts the zipper channel 2 as a whole onto the sewing machine panel; one end of the movable bracket 9 is connected to the base plate, and the other end is connected to the sewing machine panel.

[0035] like Figure 3 and Figure 7 As shown, the base plate includes a U-shaped channel base plate 203 forming a U-shaped channel and a lower engagement plate 204 connected to the front end of the U-shaped channel base plate 203; a snap-fit ​​thin plate 205 is also directly installed on one side channel of the U-shaped channel base plate 203, so that the snap-fit ​​thin plate 205 fits against the channel side of the U-shaped channel base plate 203, and the folding block 205A on it extends into the channel; one end of the U-shaped channel base plate 203 is connected to the movable bracket 9, and the other end is connected and installed to the lower engagement plate 204, which is fixed on the second folding channel in the roller channel 3.

[0036] like Figure 7 As shown, the fastening plate 205 is provided with a folding block 205A perpendicular to the surface of the fastening plate 205. The folding block 205A is integrally formed with the fastening plate 205 and can be achieved by bending. The folding block 205A is used to fasten the U-shaped channel cover plate 202 on the cover plate body.

[0037] like Figure 3 and Figure 6 , Figure 8 As shown, the cover plate body is composed of a U-shaped channel cover plate 202 and an upper interlocking plate 206 connected to the front end of the U-shaped channel cover plate 202; the U-shaped channel cover plate 202 is precisely embedded in the U-shaped channel bottom plate 203; both sides of the channel on the U-shaped channel bottom plate 203 are provided with connection holes 203A; similarly, both sides of the channel on the U-shaped channel cover plate 202 are provided with connection holes 202A.

[0038] The connecting holes 202A and 203A respectively provided at the rear end of the U-shaped channel cover plate 202 and the rear end of the U-shaped channel base 203 are fastened together by the connecting shaft bolt 7. Therefore, the front end of the U-shaped channel cover plate 202 can freely open and close up and down with the connecting shaft bolt 7 as the pivot, thereby allowing the upper biting plate 206 to engage with the lower biting plate 204 at the front end of the U-shaped channel base plate 203, which is convenient for clamping the zipper in operation.

[0039] In order to allow the U-shaped channel cover 202 to open and close freely on the U-shaped channel base plate 203, a retaining bolt 4 is inserted at the rear end of the U-shaped channel cover 202 for limiting its position. The retaining bolt 4 can abut against the U-shaped channel base plate 203 to prevent the U-shaped channel cover 202 from opening indefinitely.

[0040] In order to make the U-shaped channel cover 202 open and close freely on the U-shaped channel base plate 203 and be more flexible, a spring bolt 5 is installed in the middle part of the U-shaped channel cover 202. A spring is sleeved on the spring bolt 5 so that the U-shaped channel cover 202 has a certain elasticity when pressed down.

[0041] like Figure 3 As shown, when the U-shaped channel cover 202 is pressed down to its lowest position by the U-shaped channel base plate 203, the lower end of the folding block 205A on the fastening plate 205 presses precisely on the panel of the U-shaped channel cover 202, and the U-shaped channel cover 202 is fixed. At this time, the upper biting plate 206 and the lower biting plate are aligned and clamp the zipper. When the biting state needs to be released, it is only necessary to push the fastening plate 205 outward. Because the fastening plate 205 is relatively thin, it has a certain elasticity and can be easily pushed, so that the U-shaped channel cover 202 is disengaged from the lower end of the fastening plate. At this time, under the action of the spring set on the spring bolt 5, the U-shaped channel cover 202 springs open, and the zipper can be easily replaced.

[0042] like Figure 9 and Figure 10 As shown, a spring piece 8 is also provided on the reverse side of the upper occlusal plate 206. One end of the spring piece 8 is fixed to the reverse side of the upper occlusal plate 206, and the other end is a free-moving end.

[0043] The upper biting plate 206 is also provided with a threaded hole, which is directly opposite the spring piece 8. The biting bolt 6 is installed in the threaded hole, that is, the biting bolt 6 just abuts against the spring piece 8. When the upper biting plate 206 and the lower biting plate 204 clamp the zipper, the spring piece 8 further abuts against the surface of the zipper. The abutting force of the spring piece 8 against the surface of the zipper can be adjusted by adjusting the upper and lower biting bolt 6, so that the biting bolt 6 moves up and down.

[0044] like Figure 4As shown, the roller channel 3 includes an upright bending rod 301, a first folding channel 302 connected to the bending rod 301, and a second folding channel 303. The three are integrated to complete the first folding of the roller on both sides, and then the center folding is completed.

[0045] Both sides of the first folding channel 302 are formed with rolled edges 302A, and both sides of the second folding channel 303 are formed with folded edges 303A.

[0046] The first folding channel 302 and the second folding channel 303 are integrally formed, and an angle is formed between them to facilitate the smooth operation of the roller. The roller first wraps around the bending rod 301 in a flat plane. When the roller passes through the first folding channel 302, the two sides of the roller are folded respectively. When it runs to the first folding channel again, the roller is folded again to complete the process.

[0047] The fabric channel 1 is composed of a flat plate, which is fixed to the lower edge of the first folding channel 302 and the second folding channel 303 and is in a vertical state.

[0048] The specific operation method of this utility model is as follows: place the fabric to be hemmed on the fabric channel 1, pre-install the hemming strip in the hemming strip channel 3, then clamp the zipper with the upper and lower interlocking plates, start the machine to sew, and at this time, the hemming and zipper sewing operations are performed directly on the fabric in one stitch.
