Description

Technical Field

[0001] The utility model relates to a clothing sewing tool, in particular to a zipper cover prefabricated template. Background Art

[0002] Zippers are commonly used as connectors on clothes, but the zipper head is hard and can easily hurt the skin. To prevent this, a soft cover with an arched top is added to the starting and / or ending of the zipper. When the zipper is opened or closed, the zipper head drills into the cover and is fixed by the cover. During the production process of the cover, the cover needs to be sewn with the fabric around to form an arc-shaped arch, which is difficult to sew and requires experienced workers to complete.

[0003] The utility model patent application with publication number CN 219032562 U discloses a sewing module for pocket zippers. First, the opening of the pocket cloth is fixed on a placement plate with a rectangular groove. After the pocket is opened, the cloth is turned over using a convex strip that matches the rectangular groove. Then, the zipper and the cover are fixed on a bottom plate with a rectangular groove. The bottom plate and the rectangular groove of the placement plate are butted together. The zipper, the cover, and the pocket cloth can be sewn by sewing along the four sides of the rectangular groove. The operation of the device is cumbersome. The cloth is folded around the placement plate, and the gap between the cloth and the zipper side chain cloth is large, which is not conducive to the sewing of the zipper and the pocket cloth. The utility model patent with publication number CN 219430274 U discloses a sewing module for round-head zippers. In this scheme, after the pocket seam of the cloth piece is opened, the cloth piece needs to be re-fixed on the panel, and the panel is rotated to make the cloth piece butt with the zipper and the cover head, and then sewed. There are many operation steps, and the cloth piece is transferred and re-fixed, which will cause misalignment and uneven sewing. Utility Model Content

[0021] The technical solution of the utility model is further described below in conjunction with the accompanying drawings.

[0022] As shown in the figure, Figure 1 The expanded view of the zipper cover prefabricated template includes a base plate 1, and an arc-shaped sewing groove 11 is provided in the middle of the base plate 1. The sewing groove 11 is a through groove that penetrates the base plate 1. The sewing groove 11 allows the sewing needle to pass through and maintain the support force for the zipper 5. The base plate 1 is a rectangular base plate. The base plate 1 on both sides of the sewing groove 11 is provided with adhesive strips 12 extending to one side of the base plate 1. The adhesive strips 12 are used to bond and fix the two side chains of the zipper 5. The two sides of the base plate 1 are respectively provided with a first folding plate 3 and a second folding plate 4. The first folding plate 3 and the second folding plate 4 are both transparent plates. The side of the first folding plate 3 close to the sewing groove 11 is provided with a presser foot 31 for pressing the cloth covering the top of the zipper head. The distance between the two presser feet 31 is not less than the distance between the two ends of the sewing groove 11. The second folding plate 4 is provided with a through hole 41 corresponding to the sewing groove 11 for the zipper head and the fabric to pass through. The width of the through hole 41 is not less than the distance between the two ends of the sewing groove 11, and the length is not less than the length of the zipper head. The first folding plate 3 and the second folding plate 4 are arranged on two adjacent or opposite sides of the bottom plate 1. After the first folding plate 3 and the second folding plate 4 overlap, the zipper head 51 covered with fabric is just located between the two presser feet 31 of the first folding plate 3 and passes through the through hole 41 of the second folding plate 4. As a result, the first folding plate 3 and the second folding plate 4 restrict each other and cannot rotate around the bottom plate 1, so that the cover fabric is pressed down and fixed, which is convenient for sewing.

[0023] The side of the bottom plate 1 is also provided with a third folding plate 2, and the side of the third folding plate 2 close to the sewing groove 11 is provided with a protruding support sheet 21, and the orthographic projection area of ​​the support sheet 21 is not less than the orthographic projection area of ​​the zipper head 51, and is not greater than the orthographic projection area of ​​the through hole 41. A zipper model 22 is provided on the support sheet 21 for supporting the cover fabric so that the cover fabric is arched, and the zipper model 22 is used to simulate the zipper head, and the height of the zipper model 22 is less than the height of the zipper head. In the prior art, the zipper head is mainly composed of an upper wing plate, a lower wing plate, a guide column connecting the upper and lower wing plates, and a rod body arranged on the upper wing plate for driving the zipper head to slide. The zipper model 22 is similar in structure to the zipper head 51, but only includes the rod body, upper wing plate and guide column of the zipper head 51, that is, the zipper model 22 is consistent in shape with the zipper head 51 without the lower wing plate, but the height of the zipper model 22 is reduced. When in use, the cover wraps the upper wing plate, guide column, and rod body of the zipper head 51, so that the zipper head is fixed inside the cover. During processing, if the zipper head 51 is used as a support for sewing the cover, after sewing, the internal top height of the cover is consistent with the height of the complete zipper head. The complete zipper head 51 itself is too high, resulting in the cover arch being too high. When the zipper of the garment is closed, there is a gap between the zipper head and the cover, and it cannot be fixed inside the cover. The hole formed by the overlapping support sheet 21 and the through hole 41 is consistent with the shape of the sewing groove 11 and is on the same vertical line, serving as a guide groove for sewing.

[0024] The first folding plate 3, the second folding plate 4 and the third folding plate 2 are sequentially arranged on the three sides of the bottom plate 1 in a clockwise manner. After the third folding plate 2, the first folding plate 3 and the second folding plate 4 are folded toward the bottom plate 1, the bottom plate 1 is sequentially covered with the third folding plate 2, the first folding plate 3 and the second folding plate 4 from bottom to top. A cowhide glue 6 is respectively arranged between one side of the third folding plate 2, the first folding plate 3 and the second folding plate 4 and the upper surface of the bottom plate 1, and the cowhide glue 6 is used to bond them to form a rotating shaft / folding shaft.

[0025] When using, Figure 2 , pull the zipper head 51 back to the starting end of the zipper 5, separate the two side chains of the zipper 5, and glue the two separated side chains to the adhesive strip 12 respectively, so that the ends of the two side chains are aligned and cover the sewing groove 11. Figure 3 , rotate the third folding plate 2 so that the bottom surface of the third folding plate 2 presses the zipper 5. Figure 4As shown, the zipper model 22 just falls into the space enclosed by the suture seam 11. The inner lining and outer fabric used to make the cover are overlapped, folded in half, and clamped on the two presser feet 31 of the first folding plate 3. The fingers press the fabric above the first folding plate 3, and the first folding plate 3 is folded downward. After the first folding plate 3 is folded toward the bottom plate 1, the presser feet 31 and fingers press the fabric covering the two sides and the back of the zipper model 22, so that the fabric forms an arched zipper head cover, and then the second folding plate 4 is folded, the zipper model 22 and the fabric pass through the through hole 41, the second folding plate 4 presses the fabric above the first folding plate 3, presses the second folding plate 4, and pushes the template as a whole to the bottom of the sewing machine needle. The sewing needle passes through the through hole and sews along the sewing groove, and the cover is made.
