[0036] The technical solution of the present utility model will be further described below in conjunction with embodiments and drawings.

[0037] Please refer to Figures 1 to 4 , this application embodiment discloses a waistband sewing template for realizing the rapid sewing of a waistband with elasticated trouser loops. Specifically, the waistband sewing template includes:

[0038] Waistband inner sewing unit 10 and waistband outer sewing unit 20. The waistband inner sewing unit 10 is configured to sew the inner part of the waistband. The waistband inner sewing unit 10 includes a first bottom plate 11 and a first cover plate 12. The first cover plate 12 is rotatably connected to the first bottom plate 11. Both the first bottom plate 11 and the first cover plate 12 are provided with a first sewing groove 14 and a first positioning portion 16. When the first cover plate 12 rotates to cover the first bottom plate 11, the first sewing groove 14 on the first cover plate 12 communicates with the first sewing groove 14 on the first bottom plate 11, and the first positioning portion 16 on the first cover plate 12 is correspondingly arranged with the first positioning portion 16 on the first bottom plate 11. Correspondingly, the waistband outer sewing unit 20 is configured to sew the outer part of the waistband. The waistband outer sewing unit 20 is rotatably connected to the waistband inner sewing unit 10. The waistband outer sewing unit 20 may include a second cover plate 22 and a second bottom plate 21. The second cover plate 22 is rotatably located between the first cover plate 12 and the second bottom plate 21. The second bottom plate 21 is rotatably located on the side of the second cover plate 22 away from the first cover plate 12. Both the second cover plate 22 and the second bottom plate 21 are provided with a second sewing groove 24. And the second cover plate 22 is provided with a second positioning portion 26. When the second cover plate 22 rotates to cover the first cover plate 12 and the second bottom plate 21 rotates to cover the second cover plate 22, the second sewing groove 24 on the second bottom plate 21 communicates with the second sewing groove 24 on the second cover plate 22, and the second sewing groove 24 communicates with the first sewing groove 14. The second positioning portion 26 is positioned and connected to the first positioning portion 16.

[0039] Since the sewing and splicing of the waistband inner and the waistband outer are two processes in the waistband sewing process, in the related art, generally, the two parts are sewn separately first, and then the waistband inner and the waistband outer are spliced and sewn after the sewing is completed. A complete waistband usually includes two pieces of cut pieces, namely the waistband inner cut piece and the waistband outer cut piece. A reinforcement member may be sewn on the waistband inner cut piece, and the two need to be sewn separately before they can be joined by sewing. Moreover, if a waistband with elastic trouser loops needs to be sewn, then when the waistband inner cut piece and the waistband outer cut piece are joined by sewing, the elastic material needs to be stretched and placed between the waistband inner cut piece and the waistband outer cut piece to sew the waistband with elastic trouser loops. The whole process is very complicated, the sewing efficiency is low, and because there is no sewing reference, it is extremely easy to be misaligned during sewing, which affects the sewing quality.

[0040] However, the waistband sewing template adopted in this application, by setting the waistband inner sewing unit and the waistband outer sewing unit and designing the structures of the waistband inner sewing unit and the waistband outer sewing unit, thus, when using the waistband sewing template of this application, the process of processing the waistband is as follows:

[0041] When the waistband sewing template is placed on the table, it can be divided into an open state and a closed state according to the relative positions of the first bottom plate 11 and the second bottom plate 21. Please refer to Figure 1 , Figure 1It is a schematic structural diagram of the waistband sewing template in the opened state, that is, the first bottom plate 11 and the second bottom plate are unfolded from each other. At this time, the first bottom plate 11 and the second bottom plate 21 are relatively substantially parallel, and are unfolded by approximately 180° between them; in the covered state of the waistband sewing template, the first bottom plate 11, the first cover plate 12, the second cover plate 22 and the second bottom plate 21 are covered together.

[0042] It can be understood that when the waistband sewing template is placed on, for example, a desktop or the tabletop of a sewing machine, the waist inner sewing unit 10 can be divided into an opened state and a covered state according to the relative positions of the first bottom plate 11 and the first cover plate 12. In the opened state of the waist inner sewing unit 10, the first bottom plate 11 and the first cover plate 12 are not covered. In the covered state of the waist inner sewing unit 10, the first bottom plate 11 is covered on the first cover plate 12, the first sewing groove 14 on the first cover plate 12 communicates with the first sewing groove 14 on the first bottom plate 11, and the first positioning portion 16 on the first cover plate 12 is correspondingly arranged with the first positioning portion 16 on the first bottom plate 11.

[0043] Similarly, the waist outer sewing unit 20 can be divided into an opened state and a covered state according to the relative positions of the second bottom plate 21 and the second cover plate 22. In the opened state of the waist outer sewing unit 20, the second bottom plate 21 and the second cover plate 22 are not covered. In the covered state of the waist outer sewing unit 20, the second bottom plate 21 is covered on the second cover plate 22, and the second sewing groove 24 on the second cover plate 22 communicates with the second sewing groove 24 on the second bottom plate 21.

[0044] During sewing, place the waistband sewing template on the desktop and make it in the opened state. In the opened state, both the first bottom plate 11 and the second bottom plate 21 of the waistband sewing template are in contact with the desktop, and the first bottom plate 11 and the second bottom plate 21 are relatively substantially parallel. Rotate the first cover plate 12 to the side where the first bottom plate is located, so that the waist inner sewing unit 10 is in the covered state. Similarly, rotate the second cover plate 22 to the side where the second bottom plate is located, so that the waist outer sewing unit 20 is in the covered state.

[0045] Rotate the second cover plate 22 to the side where the first bottom plate is located to make the waist outer sewing unit 20 in the opened state, and place the waist outer cut piece on the second bottom plate 21 or the second cover plate 22 to completely cover the second sewing groove 24. The waist outer cut piece is a strip-shaped fabric with a long side and a short side. When placing it, the long side can be used to cover along the second sewing groove 24. After the waist outer cut piece is placed, rotate the second cover plate 22 to the second bottom plate to make the waist outer sewing unit 20 in the covered state.

[0046] Similarly, rotate the first cover plate 12 to the side where the second bottom plate is located to make the waist sewing unit 10 in an open state. Place the waist cut piece on the first bottom plate 11 or the first cover plate 12 so that it completely covers the first sewing groove 14. The waist cut piece is a strip of fabric with a long side and a short side. When placing it, the long side can be placed along the first sewing groove 14 for covering. After the waist cut piece is placed, rotate the first cover plate 12 to the first bottom plate to make the waist sewing unit 10 in a closed state.

[0047] Rotate the waist sewing unit 10 to the side where the second bottom plate is located, or rotate the waist surface sewing unit 20 to the side where the first bottom plate is located, so that the entire waist sewing template is in a closed state.

[0048] The above process realizes placing the waist cut piece between the first bottom plate 11 and the first cover plate 12, placing the waist surface cut piece between the second bottom plate 21 and the second cover plate 22, and closing the waist sewing unit 10 and the waist surface sewing unit 20. The ways to achieve this placement result include but are not limited to the above process, and no specific limitation is made here.

[0049] Put the waist sewing template into the sewing machine, and the sewing machine sews the waist cut piece and the waist surface cut piece together along the first sewing groove 14 and the second sewing groove 24 to complete the sewing of the waist. It can be seen that by using the waist sewing template of the present application, manual alignment and fixation of the waist cut piece and the waist surface cut piece can be omitted, the accuracy of the alignment of the waist cut piece and the waist surface cut piece is improved, and thus the quality of the splicing sewing of the waist cut piece and the waist surface cut piece is ensured. At the same time, by flipping the waist sewing unit and the waist surface sewing unit, the sewing of the waist can be completed at one time, improving the efficiency of waist sewing production.

[0050] Exemplarily, each of the above plates is a rectangular plate. Then, the above first side and second side can be the two sides of the first bottom plate along the width direction, or can also be the two sides along the length direction, which can be specifically set according to the actual situation, and no specific limitation is made in this embodiment.

[0051] It can be understood that each plate can be rotatably connected by using transparent connecting devices such as transparent tape and transparent hinges, and no specific limitation is made in this embodiment.

[0052] It can be understood that in order to further improve the accuracy of the alignment of the waist cut piece and the waist surface cut piece, positioning lines can be set on at least one of the first bottom plate 11, the first cover plate 12, the second bottom plate 21 and the second cover plate 22, so that when placing the cut piece, it can be accurately placed in the appropriate position to avoid displacement and deviation of the cut piece. Exemplarily, positioning lines can be set on the first bottom plate 11, the first cover plate 12, the second bottom plate 21 and the second cover plate 22, and in this way, the positioning effect is better.

[0053] It can be understood that the positioning line can be a scoring line provided on the first bottom plate 11, the first cover plate 12, the second bottom plate 21 and the second cover plate 22, or it can also be an indicating line adhered to the first bottom plate 11, the first cover plate 12, the second bottom plate 21 and the second cover plate 22, so as to realize the positioning and placement of the cut pieces on the plate.

[0054] In some optional embodiments, the first positioning portion 16 on the first bottom plate 11 is a fixing pin, and the first positioning portion 16 on the first cover plate 12 and the second positioning portion 26 on the second cover plate 22 are both fixing holes.

[0055] In other optional embodiments, the first positioning portions 16 on the first bottom plate 11 and the first cover plate 12 are both fixing holes, and the second positioning portion 26 on the second cover plate 22 is a fixing pin.

[0056] By setting the structures of the first positioning portion 16 and the second positioning portion 26 as fixing pins or fixing holes, the waistband cut piece is penetrated and fixed between the first bottom plate 11 and the first cover plate 12 by the fixing pins, thereby preventing the waistband cut piece from shifting during the sewing process and affecting the quality of the waistband. At the same time, since the trouser loop is sewn between the waistband cut piece and the waist surface cut piece, and the first positioning portion 16 and the second positioning portion 26 can fix the first cover plate 12 and the second cover plate 22, the trouser loop located between the two cut pieces can also be fixed. Therefore, the trouser loop can also be fixed when sewing the waistband with trouser loops, further improving the quality of sewing the waistband with trouser loops.

[0057] It can be understood that in other possible embodiments, the first positioning portion 16 or the second positioning portion 26 can also be simultaneously set as a fixing pin and a fixing hole. The first cover plate 12 can be provided with both a fixing pin and a fixing hole at the same time, and the positions of the fixing pin and the fixing hole on the first cover plate are staggered. For example, a fixing pin is provided on one side of the first cover plate, and a fixing hole is provided on the other side of the first cover plate, and the positions of the fixing hole and the fixing pin on the other side are staggered from each other. In this way, the first bottom plate 11 can also be provided with a fixing pin and a fixing hole, the second positioning portion 26 of the second cover plate 22 can be a fixing hole, and two fixing holes are provided on the second cover plate. Thus, the fixing pin on the first bottom plate can pass through the fixing hole on the first cover plate and one of the fixing holes on the second cover plate to achieve fixation. The fixing pin on the first cover plate can pass through the fixing hole on the first bottom plate and the other fixing hole on the second cover plate, thereby achieving fixation.

[0058] It can be understood that the number of the first positioning portions on the first bottom plate and the first cover plate can be one or more. Correspondingly, the number of the second positioning portions on the second cover plate can also be one or more accordingly. It can be specifically set according to the length of the cut piece to be fixed, and this embodiment does not make specific limitations on this.

[0059] Exemplarily, there are four first positioning parts on both the first bottom plate 11 and the first cover plate 12, and these four positioning parts are all fixing holes. Correspondingly, there are also four second positioning parts 26 on the second cover plate 22, and these four second positioning parts are all fixing pins.

[0060] Optionally, the shapes of the first sewing groove and the second sewing groove can be set according to the shape of the waistband to be sewn. For example, both the first sewing groove and the second sewing groove can be long strip grooves, and the first sewing groove and the second sewing groove can extend along the length direction of the plate where they are located.

[0061] In some embodiments, considering the fixing effect of the first positioning part 16 and the second positioning part 26 and the need to sew the actual sample line for attaching the waistband simultaneously during sewing, both the first sewing groove 14 and the second sewing groove 24 can include two sub-sewing grooves and the fixing part is arranged between the two sub-sewing grooves. Specifically, the first sewing groove 14 includes two first sub-sewing grooves, the two first sub-sewing grooves are arranged at intervals along the first direction, and the first positioning part 16 is located at the interval between the two first sub-sewing grooves. Correspondingly, the second sewing groove 24 includes two second sub-sewing grooves, the two second sub-sewing grooves are arranged at intervals along the first direction, and the second positioning part 26 is located at the interval between the two second sub-sewing grooves. Among them, the first bottom plate 11 has opposite first and second sides, the first cover plate 12 is rotatably connected to the first side, and the first direction is the direction from the second side to the first side. Exemplarily, the first sewing groove 14 of the first bottom plate 11 includes two first sub-sewing grooves 14a and 14b, and the two first sub-sewing grooves 14a and 14b are arranged at intervals along the first direction. Similarly, the first sewing groove 14 of the first cover plate 12 also includes two first sub-sewing grooves 14a and 14b.

[0062] In the above embodiments, by setting the two sub-sewing grooves and their relative positions with the positioning parts, while the positioning parts can effectively fix the fabric, the sewing machine can also sew along the sewing grooves, making rational use of the space of the first bottom plate 11, the first cover plate 12 and the second cover plate 22.

[0063] In the above embodiments, by providing two sub-sewing grooves on each of the first bottom plate 11, the first cover plate 12, the second bottom plate 21 and the second cover plate 22, the actual sample line for attaching the waistband can be sewn simultaneously when sewing the waistband, reducing the separate process of drawing the actual sample line on the comparison template. At the same time, setting the first positioning part 16 and the second positioning part 26 at the interval between the two sub-sewing grooves can be used to fix the waistband, so that the first positioning part 16 and the second positioning part 26 are located within the area covered by the cut piece, thereby being able to reliably fix the cut piece, improving the reliability of waistband sewing and further ensuring the quality of waistband sewing.

[0064] In some embodiments, anti-slip structures are provided on the outer perimeters of the first sewing groove 14 and the second sewing groove 24. The anti-slip structures are used to increase the friction between the cut pieces and the bottom plate and the cover plate, and to prevent the cut pieces from moving relatively during the sewing process. Optionally, the anti-slip structures include, but are not limited to, structures such as strips and rings that can surround the sewing grooves, and the materials used include, but are not limited to, materials with relatively large friction such as double-sided tape, sandpaper, and sponge. There is no limitation here.

[0065] Please refer to Figure 3 and Figure 6 As shown, in some embodiments, in order to sew a waistband with a stretchable trouser loop, by cooperating with the first positioning portion 16 and the second positioning portion 26, and providing hollow portions 27 on both the second bottom plate 21 and the second cover plate 22, the hollow portions are configured to sew the trouser loops of the waistband. Please refer to Figure 6 , Figure 6 which is a schematic structural diagram of the placement of the elastic band and the elastic band cover cloth of the waistband sewing template disclosed in Embodiment 1 of the present utility model. Exemplarily, the hollow portion 27 can be set as at least one sewing groove. Based on the sewing groove of the hollow portion 27, a waistband with a stretchable trouser loop can be processed. The processing process is as follows: Place the waist lining cut piece between the first bottom plate 11 and the first cover plate 12, and after placing the waist surface cut piece between the second bottom plate 21 and the second cover plate 22, place the stretched elastic band 41 on the second cover plate 22 so that the second positioning portion 26 on the second cover plate 22 fixes the elastic band 41. For the aesthetics of the stretchable trouser loop, an elastic band cover cloth 42 can also be placed on the elastic band 41 on the second cover plate 22 so that the second positioning portion 26 fixes the elastic band cover cloth 42. Place the waistband sewing template into the sewing machine, and the sewing machine sews the waist surface cut piece, the elastic band 41, and the elastic band cover cloth 42 along the sewing groove of the hollow portion 27. Among them, the material of the elastic band 41 includes, but is not limited to, elastic materials such as rubber, polyester, nylon, and silk. The number and position of the sewing grooves provided in the hollow portion are set according to the stitch of the stretchable trouser loop, and there is no specific limitation here.

[0066] After the stretchable trouser loop is sewn, cover the waist lining sewing unit and the waist surface sewing unit with each other, and then place the waistband sewing template into the sewing machine. The sewing machine completes the sewing of the waistband through the first sewing groove 14 and the second sewing groove 24.

[0067] The hollow portion 27 in the above embodiment enables the sewing of a stretchable trouser loop when sewing the waistband, and the second positioning portion 26 fixes the stretched elastic band 41 to the waistband sewing template, making the sewing stitch of the waistband with a stretchable trouser loop uniform, thereby improving the quality of sewing the waistband.

[0068] In some embodiments, due to the stability of the structure of the hollow portion 27, that is, once the structure is set and formed, it is difficult to transform into other structural styles. Considering the diversity of the sewing thread traces of the elastic waistband during sewing, a connecting member 28 may be provided on the second bottom plate 21. The connecting member 28 is located on the outer periphery of the hollow portion 27 on the second bottom plate 21. The waistband sewing template further includes a pressing plate 30. The pressing plate 30 is detachably connected to the connecting member 28, and a third sewing groove 34 is provided on the pressing plate 30. The third sewing groove 34 corresponds to and communicates with the hollow portion 27, so that the third sewing groove 34 and the hollow portion 27 are jointly configured to sew the waistband of the elastic waistband. Through the cooperation of the pressing plate 30 and the hollow portion 27, not only can the waistband with an elastic waistband be sewn, but also the customization of the thread trace of the waistband can be realized. Exemplarily, in addition to being set as the structure of a sewing groove, the hollow portion 27 can also be set as a hollow rectangle. The hollow rectangle can communicate with the third sewing groove 34 on the pressing plate 30. The third sewing groove 34 on the pressing plate 30 may include three third sub-sewing grooves, namely 34a, 34b, and 34c. The three third sub-sewing grooves are arranged along the first direction (as Figure 4 shown, this first direction is the extending direction of the pressing plate, that is, Figure 4 the up-and-down direction along the paper surface in

[0069] ). When sewing the elastic waistband, replace the pressing plate 30 according to the customized thread trace style of the elastic waistband. First, remove the previous pressing plate 30 from the connecting member 28, and fix the required pressing plate 30 on the waistband sewing template. Then, put the waistband sewing template into the sewing machine, and the sewing machine sews the waist surface piece and the waistband along the three sub-sewing grooves of the pressing plate. When it is necessary to change the thread trace of the waistband, only need to detach the pressing plate 30 from the connecting member 28 and replace it with the pressing plate 30 with the required thread trace.

[0070] In some embodiments, in order to reliably fix the pressing plate 30 and the connecting member 28, a fastening structure 28b and / or a magnetic attraction structure 28a are provided on the connecting member 28. Please refer to Figure 5 , Figure 5This is a schematic structural diagram of the connection state between the pressing plate and the second bottom plate of the waistband sewing template disclosed in the first embodiment of the present utility model. The connecting member 28 on the second bottom plate 21 includes a fastening structure 28b and / or a magnetic attraction structure 28a. Optionally, when the connecting member 28 includes a fastening structure 28b, the connecting member 28 includes a connecting body and a first fastening portion 28b1 provided on the connecting body. A second fastening portion 32 corresponding to the first fastening portion 28b1 is provided on the pressing plate 30, and the second fastening portion 32 is fastened and connected to the first fastening portion 28b1. The first fastening portion 28b1 of the connecting member 28 can be tightly connected to the second fastening portion 32, ensuring the accurate placement position of the pressing plate 30 and preventing relative movement of the pressing plate 30 during the sewing process.

[0071] When the connecting member includes a magnetic attraction structure, the magnetic attraction structure can be directly adhered to the first bottom plate through, for example, tape or glue. Correspondingly, a magnetic attraction structure is adhered to the pressing plate at the corresponding position. Optionally, the magnetic attraction structure can be, for example, a magnet, a metal part, etc. For example, a magnet is provided on the first bottom plate and a metal part is provided on the pressing plate, or vice versa.

[0072] When the connecting member includes a fastening structure and a magnetic attraction structure, the connecting member can be a connecting plate, which can be fixed to the first bottom plate. At this time, a fastening structure can be provided on the connecting plate, and a hole can be formed in the gap of the fastening structure 28b, and a magnetic attraction structure 28a can be arranged in the hole. Exemplarily, the hole in the gap is set as a circular hole, and a circular thin sheet magnet is arranged in the circular hole. The size of the circular thin sheet magnet is less than or equal to the size of the circular hole, so that the circular thin sheet magnet can be placed in the circular hole. Among them, the diameter of the circular thin sheet magnet is less than or equal to the diameter of the circular hole, and the thickness is greater than the depth of the circular hole. After the circular thin sheet magnet is placed in the hole, glue, transparent tape, etc. can be used to fix the magnet in the hole. By arranging the magnetic attraction structure 28a in the gap of the fastening structure 28b, the rationality of the space utilization of the pressing plate 30 is improved, so that more third sewing grooves 34 can be arranged on the pressing plate 30.

[0073] In some embodiments, limiting holes 29 are provided on both the second cover plate 22 and the second bottom plate 21. The limiting holes 29 are located at the intervals between the two first sub-sewing grooves and are arranged at intervals with the first positioning portion 16. The limiting holes 29 are configured as accessories for sewing the waistband. Such accessories may include, but are not limited to, waistband accessories such as Velcro and decorative pieces. Exemplarily, based on the limiting holes 29, waistband accessories such as sewing Velcro and decorative pieces can be sewn on the waist surface cut piece during the sewing process of the waistband. The processing procedure is as follows: After placing the waist surface cut piece between the second bottom plate 21 and the second cover plate 22, rotate the second cover plate 22 to cover the second bottom plate, so that the waist surface sewing unit is in a covered state. Place the waistband accessory in the limiting hole 29, and then place the waistband sewing template on the sewing machine. The sewing machine sews around the edge of the limiting hole 29 to sew the waistband accessory. The waistband sewing process is the same as above and will not be elaborated here. It can be understood that the size of the limiting hole 29 can be set according to the size of the waistband accessory, so that the waistband accessory can be placed in the limiting hole 29, and the sewing machine can sew along the edge of the limiting hole 29.

[0074] In addition, the number of the limiting holes 29 can be set according to the number of the limiting holes 29 that the second cover plate 22 and the second bottom plate 21 can accommodate. Generally, considering the aesthetics and practicality of the waistband accessory, one limiting hole 29 can be provided on each side of the second positioning portion 26.

[0075] Through the limiting holes 29 in the above embodiments, it is possible to sew the waistband accessory simultaneously during the sewing process of the waistband, and the waistband accessories such as Velcro and decorative pieces can be accurately sewn on the waist surface cut piece more precisely along the edge of the limiting hole 29, thereby improving the quality of sewing the waistband.

[0076] In some embodiments, the first cover plate 12, the first bottom plate 11, the second cover plate 22, the second bottom plate 21, and the pressing plate 30 are all made of transparent polyvinyl chloride plates. The transparent polyvinyl chloride plates not only enable the position of the fabric to be observed when placing the cut piece, so that the position or angle of the fabric can be adjusted in a timely manner, but also the light weight of the polyvinyl chloride plates makes the waistband sewing template more convenient to turn over and carry.

[0077] In some embodiments, both the first bottom plate 11 and the second bottom plate 21 can be long strip-shaped. The lengths of the first bottom plate and the second bottom plate are both set to 100 cm, the widths are set to 40 cm, and the thicknesses are set to 1 mm. The lengths of the first cover plate 12 and the second cover plate 22 are set to 100 cm, the widths are set to 20 cm, and the thicknesses are set to 1 mm. By setting the lengths of the first bottom plate 11, the second bottom plate 21, the first cover plate 12, and the second cover plate 22 to 100 cm, that is, each of the above plates has a certain length, so that longer cut pieces can be placed, and at the same time, the contact area between the waistband sewing template and the waist lining cut piece and the waist face cut piece can be increased, avoiding the situation of deviation between the corresponding bottom plate and the cover plate of the cut piece due to too small contact area, thereby improving the reliability of fixing the cut piece. At the same time, setting the widths of the first cover plate 12 and the second cover plate 22 to be smaller than the widths of the first bottom plate 11 and the second bottom plate 21 makes it more convenient and easier to open the waistband sewing template, and reduces the ineffective area on the first cover plate 12 and the second cover plate 22, reducing the cost of making the waistband sewing template.

[0078] In a second aspect, the present application also provides a sewing machine, which may include the waistband sewing template described in the first aspect above.

[0079] The above has introduced the waistband sewing template and the sewing machine disclosed in the embodiments of the present invention in detail. Specific examples are used in this article to elaborate on the principles and implementation manners of the present invention. The descriptions of the above embodiments are only used to help understand the waistband sewing template and the sewing machine of the present invention and its core idea; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manners and application scopes.
