[0043] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0044] In the present utility model, the orientation or positional relationship indicated by terms such as "upper", "lower", "vertical", "horizontal", "lateral", "longitudinal", etc. is based on the orientation or positional relationship shown in the accompanying drawings. These terms are mainly used to better describe the present utility model and its embodiments, and are not used to limit that the indicated devices, elements, or components must have a specific orientation, or be constructed and operated in a specific orientation.

[0045] Moreover, in addition to being able to represent the orientation or positional relationship, some of the above terms may also be used to represent other meanings. For example, the term "upper" may also be used to represent a certain attachment relationship or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in the present utility model can be understood according to specific circumstances.

[0046] In addition, the terms "arrange", "be provided with", "connect" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or there is an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0047] In addition, terms such as "first", "second", etc. are mainly used to distinguish different devices, components or parts (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, components or parts. Unless otherwise specified, the meaning of "a plurality" is two or more.

[0048] In the process of manufacturing garment pleats, in order to ensure the high quality and standardization of garment pleat production, it is usually necessary to first fold the fabric in advance using a template to form pleats, and then sew according to the stitching lines given by the template. However, during the sewing process, the situation of misaligned stitching positions often occurs, resulting in inconsistent widths of each pleat, leading to frequent rework. This not only affects the product quality of the garment, but also increases the production cost. For example, after sewing is completed, the fabric with pleats needs to be taken out. In order to prevent the pleat stitches from falling off, it is usually necessary to slightly bend the pressing plate. As a result, after the fabric is taken out multiple times, the movable connections between the outermost first pressing plate and the second pressing plate and the bottom plate will be bent, resulting in the first sewing groove being covered due to the misalignment of the external first pressing plate and the second pressing plate, so that not all the pleats are sewn. This is unqualified for garment products. Taking apart the pleats and sewing them again will not only increase the production cost, but also may affect the aesthetics of the garment due to different stitching lines.

[0049] Based on this, for the pleat sewing template and sewing machine disclosed in this application, after the fabric is laid flat on the bottom plate of the pleat sewing template and the first pressing plate is covered, the fixing buckle is buckled with the first fixing hole, which can effectively prevent the first pressing plate from misaligning and moving while clamping the fabric. Subsequently, the unclamped fabric is flipped from one side of the first pressing plate to the other side, the second pressing plate is covered, and when the fixing buckle passes through the first fixing hole, it is buckled with the second fixing hole to prevent the fabric between the first pressing plate and the second pressing plate from sliding, and at the same time, the misalignment of the first pressing plate and the second pressing plate can be avoided. Then, the fabric is folded along the support bar side of the second pressing plate so that the fabric is folded on the second pressing plate along the support bar, ensuring that the second pressing plate has the fabric protruding due to the support bar. By analogy, after all the pleats are folded, the cover plate is covered, and the pleat sewing template is placed on the sewing machine to complete the sewing of the pleats. Due to the more stable buckling connection relationship between the fixing buckle and the first fixing hole and the second fixing hole, the stability of the pressing plate during the pleat folding process and the sewing process can be improved, the occurrence of pressing plate misalignment can be reduced, the sewing quality of the product can be guaranteed, the defective rate and production cost can be reduced, and the production efficiency can be significantly improved.

[0050] The technical solutions of the present utility model will be further described below in conjunction with embodiments and drawings.

[0051] Please refer to Figure 1-2 , Figure 1 which is a schematic diagram of the pleat sewing template provided by the embodiment of this application, Figure 2Schematic structural diagram of the bottom plate provided by the embodiments of the present application. The embodiments of the present application provide a pleat sewing template 100, which includes a bottom plate 1, a cover plate 2, a plurality of first pressing plates 31 and a plurality of second pressing plates 32.

[0052] The bottom plate 1 is provided with a plurality of first sewing grooves 4 and a plurality of fixing buttons 81. The plurality of first sewing grooves 4 are arranged at intervals in an arc shape along the first direction. The fixing buttons 81 are located on one side of the first sewing grooves 4. The plurality of fixing buttons 81 are arranged at intervals in an arc shape along the first direction. Along the first direction, the fixing buttons 81 and the first sewing grooves 4 are alternately arranged.

[0053] Considering that the pleat sewing template of the present application is used for sewing the pleats of a pleated skirt, therefore, the plurality of first sewing grooves are arranged in an arc shape along the first direction, which can match the shape of the skirt of the pleated skirt, thereby facilitating the sewing of the pleats.

[0054] Optionally, the first direction can be a direction parallel to the rotation connection side of the bottom plate 1 and the cover plate 2, or a direction perpendicular to the rotation connection side, or other directions. Hereinafter, the case where the first direction is parallel to the rotation connection side will be taken as an example for detailed introduction.

[0055] The cover plate 2 is rotatably connected to the bottom plate 1. The cover plate 2 is provided with a plurality of second sewing grooves 5. Each second sewing groove 5 corresponds to each first sewing groove 4. When the cover plate 2 is rotated and overlapped on the bottom plate 1, the respective second sewing grooves 5 are respectively communicated with the corresponding first sewing grooves 4.

[0056] A plurality of first pressing plates 31 are rotatably connected to the bottom plate 1 and are located between the bottom plate 1 and the cover plate 2. The plurality of first pressing plates 31 are arranged at intervals along the first direction, and a first sewing groove 4 is correspondingly arranged between two adjacent first pressing plates 31; a first fixing hole 82 is provided on the first pressing plate 31 corresponding to the fixing button 81, and the first fixing hole 82 is configured to be connected to the fixing button 81 when the first pressing plate 31 is rotated and pressed on the bottom plate 1.

[0057] A plurality of second pressing plates 32 are rotatably connected to the bottom plate 1 and are located between the first pressing plates 31 and the cover plate 2. Each second pressing plate 32 corresponds to each first pressing plate 31, and each second pressing plate 32 is configured to be rotatable to press on the corresponding first pressing plate 31; a second fixing hole 83 is provided on the second pressing plate 32 corresponding to the first fixing hole 82, and the second fixing hole 83 is configured to be communicated with the first fixing hole 82 when the second pressing plate 32 is rotated and pressed on the first pressing plate 31, so that the fixing button 81 is connected to the first fixing hole 82 and the second fixing hole 83.

[0058] On one side of each second pressing plate 32, there is a support bar 7. The projections of the support bars 7 on the bottom plate 1 are respectively located within the ranges corresponding to the first sewing grooves 4. The support bars 7 are configured to support the fabric so that the fabric is folded along the support bars 7 onto the second pressing plate 32.

[0059] It can be understood that the number of the above-mentioned first pressing plates and second pressing plates can be set according to the number of pleats to be sewn. For example, both the first pressing plate and the second pressing plate can be 6 pieces, 7 pieces or more.

[0060] Exemplarily, both the first pressing plate and the second pressing plate can be 10 pieces. Correspondingly, there are 9 first sewing grooves 4 and 10 fixing buttons 81 on the bottom plate 1, 9 second sewing grooves 5 on the cover plate 2, 1 first fixing hole 82 on each first pressing plate 31, 1 second fixing hole 83 on each second pressing plate 32, and a support bar 7 is provided on the right side of the second pressing plate 32. The first pressing plates 31, the second pressing plates 32 and the fixing buttons 81 are distinguished from No. 1 to No. 10 in the first direction. During the pleat folding process, first open the cover plate 2 and all the first pressing plates 31 and second pressing plates 32, place the fabric according to the positioning lines on the bottom plate 1, and then cover the first No. 1 pressing plate 31, the first No. 1 second pressing plate 32 and the second No. 1 pressing plate 31, so that the first fixing button 81 and the first fixing hole 82 of the first No. 1 pressing plate, the second fixing hole 83 of the first No. 1 second pressing plate are completely buckled, and the second fixing button 81 and the second fixing hole 82 of the second No. 1 pressing plate are completely buckled to ensure that the fabric does not slide. Then, fold the left side fabric to the right along the left side of the second No. 1 pressing plate 31, cover the second No. 1 second pressing plate 32, so that the second fixing button 81 and the second fixing hole 83 of the second No. 1 second pressing plate are completely buckled, and then fold the fabric to the left along the support bar 7 on the right side of the second No. 1 second pressing plate 32 to complete the folding of the first pleat. By analogy, after the pleats of other pressing plates are folded in sequence, cover the cover plate 2 to complete the pleat folding of the whole piece of fabric.

[0061] It can be seen that by using the pleat sewing template of the present application, during the pleat folding process of the fabric, using this pleat sewing template to fold the pleats of the fabric can not only simplify and standardize the complex process, but also avoid the dislocation phenomenon of the first pressing plate 31 and the second pressing plate 32 during the pleat folding process and the sewing process through the connection structure of buckling the fixing button 81 on the bottom plate 1 with the first fixing hole 82 of the first pressing plate 31 and the second fixing hole 83 of the second pressing plate 32, which can improve the stability of each pressing plate in the pleat sewing template and ensure the sewing quality.

[0062] Optionally, the buckling structure of the fixing button and the fixing hole can have one pair or multiple pairs on the bottom plate 1, the first pressing plate 31 and the second pressing plate 32, but is not limited thereto.

[0063] In some embodiments, the bottom plate 1 has opposite first and second sides 11 and 12. The cover plate 2, the first pressing plate 31, and the second pressing plate 32 are all rotatably connected to the first side 11. In the direction from the second side 12 to the first side 11, the first sewing groove 4 and the fixing buckle 81 are arranged in sequence. Please refer to Figure 2 , in the top view structure diagram of the bottom plate 1, the upper side of the bottom plate 1 is the first side 11, and the lower side of the bottom plate 1 is the second side 12. The cover plate 2, the first pressing plate 31, and the second pressing plate 32 are all rotatably connected to the first side 11 of the bottom plate 1. By setting the rotatable connection sides on the same side, it can ensure the convenient opening and closing of the first pressing plate 31, the second pressing plate 32, and the cover plate 2 during the pleat folding process. In the direction from the second side 12 to the first side 11, the first sewing groove 4 and the fixing buckle 81 are arranged in sequence, that is, the fixing buckle 81 is closer to the first side 11. That is to say, the first fixing hole 82 on the first pressing plate 31 and the second fixing hole 83 on the second pressing plate 32 are closer to the end of the pressing plate. By setting the buckling of the fixing buckle and the fixing hole at the end of the pressing plate, it can prevent the first pressing plate 31 and the second pressing plate 32 from being misaligned during the pleat folding process and the sewing process, and can also reduce the influence of the repeated process of taking out the sewn fabric on the first pressing plate 31, the second pressing plate 32, and the bottom plate 1, which is beneficial to improving the service life of the template and reducing the production cost.

[0064] In some embodiments, a plurality of first magnetic members 91 are provided on the bottom plate 1. The plurality of first magnetic members 91 are arranged at intervals in an arc shape along the first direction. Along the first direction, the first magnetic members 91 and the first sewing grooves 4 are arranged alternately, and the first magnetic members 91 are located between two adjacent first sewing grooves 4. Corresponding to the first magnetic members 91 on the first pressing plate 31, a plurality of second magnetic members 92 are provided. The second magnetic members 92 are configured to be magnetically connected to the corresponding first magnetic members 91 respectively when the first pressing plate 31 rotates and presses on the bottom plate 1. Corresponding to the second magnetic members 92 on the second pressing plate 32, a plurality of third magnetic members 93 are provided. The third magnetic members 93 are configured to be magnetically connected to the corresponding second magnetic members 92 respectively when the second pressing plate 32 rotates and presses on the first pressing plate 31.

[0065] Please refer to again Figure 1, there are 20 first magnetic members 91 provided on the bottom plate 1, which are arranged at an arc interval along the first direction, and between every two adjacent first sewing grooves 4, 2 first magnetic members 91 are provided along the direction from the second side 12 to the first side 11. There are 2 corresponding second magnetic members 92 provided on the first pressing plate 31, and 2 corresponding third magnetic members 93 provided on the second pressing plate 32. When the first pressing plate 31 rotates and presses on the bottom plate 1, and the second pressing plate 32 rotates and presses on the first pressing plate 31, the first magnetic member 91 magnetically attracts with the corresponding second magnetic member 92 and third magnetic member 93. During the pleat folding process of the fabric, by providing magnetic members on the bottom plate 1, the first pressing plate 31 and the second pressing plate 32, it is possible to fix the middle side and the second side 12 of the fabric by using magnetic members while the fixed buckle 81, the first fixing hole 82 and the second fixing hole 83 are buckling and fixing the first side 11 of the fabric, preventing the fabric from sliding. At the same time, the method of fixing the fabric by magnetic members will not damage the surface of the fabric and affect the product quality.

[0066] Optionally, the first magnetic member 91, the second magnetic member 92 and the third magnetic member 93 can be magnets, or other magnetic materials, but not limited thereto; the sizes of the first magnetic member 91, the second magnetic member 92 and the third magnetic member 93 can be magnetic members with the same shape and size, or magnetic members with different shapes and sizes, but not limited thereto.

[0067] In some embodiments, the bottom plate 1 is provided with a first mounting hole (not shown), and the first magnetic member 91 is mounted in the first mounting hole; the first pressing plate 31 is provided with a second mounting hole (not shown), and the second magnetic member 92 is mounted in the second mounting hole. When the first pressing plate 31 rotates and presses on the bottom plate 1, the first mounting hole communicates with the second mounting hole; the second pressing plate 32 is provided with a third mounting hole (not shown), and the third magnetic member 93 is mounted in the third mounting hole. When the second pressing plate 32 rotates and presses on the first pressing plate 31, the first mounting hole communicates with the second mounting hole. Please refer to Figure 1 , the first magnetic member 91 on the bottom plate 1 is mounted in the first mounting hole, the second magnetic member 92 on the first pressing plate 31 is mounted in the second mounting hole, and the third magnetic member 93 on the second pressing plate 32 is mounted in the third mounting hole. Exemplarily, the first mounting hole, the second mounting hole and the third mounting hole are all circular mounting holes with the same shape and size. When all the pressing plates are closed, the first mounting hole, the second mounting hole and the third mounting hole communicate with each other. The first magnetic member 91, the second magnetic member 92 and the third magnetic member 93 are mounted in the respective circular mounting holes, which can effectively prevent the movement of the magnetic members during the pleat folding process of the fabric, thereby avoiding problems such as the misalignment of the pressing plates caused by the misalignment of the magnetic members, or the magnetic attraction ability being insufficient to fix the fabric, which is beneficial to improving the sewing quality.

[0068] Optionally, each magnetic member can be a magnetic member attached to each mounting hole, or a magnetic member directly embedded in each mounting hole, but is not limited thereto.

[0069] In some other embodiments, each magnetic member can be installed in the corresponding mounting hole through a transparent tape. This method of encapsulating the magnetic member with a transparent tape can not only ensure the transparency of the pleat sewing template 100, but also facilitate the replacement of the magnetic member with weakened magnetic attraction ability, thereby ensuring the stability of the fabric during the pleat folding process and the sewing process, preventing the fabric from sliding, and ensuring the product quality.

[0070] Please refer to Figures 1 to 4 , in some embodiments, the bottom plate 1 includes a cushion plate portion 61 and a main plate portion 62. The main plate portion 62 has opposite first side 11 and second side 12. The first sewing groove 4 extends along the direction from the second side 12 to the first side 11; the cushion plate portion 61 is disposed on the main plate portion 62 and is adjacent to the first side 11. The first pressing plate 31 and the second pressing plate 32 are both rotatably connected to the cushion plate portion 61, and the cover plate 2 is rotatably connected to the first side 11. Figure 3 It is a schematic side view of the fully unfolded pressing plates provided by the embodiment of the present application. As Figure 3 shown, the first pressing plate 31 is rotatably connected to the lower part of the cushion plate portion 61, and the second pressing plate 32 is rotatably connected to the upper part of the cushion plate portion 61. By adding the cushion plate portion 61, not only can the connection strength of the rotational connection between the first pressing plate 31, the second pressing plate 32 and the cushion plate portion 61 be improved to prevent the detachment of the first pressing plate 31 and the second pressing plate 32, but also, since the cushion plate portion 61 is an intermediate connection structure, it is convenient to replace the pressing plates, which can improve the service life of the pleat sewing template 100 and is beneficial to reducing the production cost.

[0071] In some embodiments, by providing a snap-fit structure of a fixing buckle and a fixing hole, a magnetic member structure and a cushion plate on the pleat sewing template 100, it is ensured that the first pressing plate 31 and the second pressing plate 32 can rotate on the bottom plate 1. At the same time, after placing the fabric on the bottom plate 1, by rotating and pressing the first pressing plate 31 and the second pressing plate 32, the fixing buckle and the fixing hole can be snapped together, and the magnetic members can attract each other magnetically, thereby ensuring the fixation between the bottom plate 1, the first pressing plate 31 and the second pressing plate 32, and preventing the fabric located between the three from sliding.

[0072] Please refer to Figures 3-4 , in which Figure 4 is a schematic side view of the fully closed pressing plates provided by the embodiment of the present application. As Figure 3As shown, the cushion plate portion 61 is arranged close to the first side 11 of the bottom plate 1, and the cushion plate portion 61 includes upper and lower layers, so as to realize the elevation design of the first pressing plate and the second pressing plate. When the first pressing plate and the second pressing plate are pressed on the bottom plate, a space can be reserved between the bottom plate and the first pressing plate and the second pressing plate for placing the cut pieces. The bottom plate 1 is also provided with a fixing buckle 81 at a position close to the second side 12 of the cushion plate portion 61, and two first mounting holes are arranged in the middle of the bottom plate 1. Two first magnetic members 91 are encapsulated in the first mounting holes. The first pressing plate 31 is provided with one first fixing hole 82 and two second mounting holes, and one second magnetic member 92 is encapsulated in the second mounting holes. The second pressing plate 32 is provided with one second fixing hole 83 and two third mounting holes, and one third magnetic member 93 is encapsulated in the third mounting holes. The shapes and sizes of the magnetic members and the mounting holes are the same.

[0073] When Figure 3 the template shown is closed, please combine Figure 4 , during the pleat folding process, after the first pressing plate 31 rotates and presses on the bottom plate 1, the second pressing plate 32 rotates and presses on the first pressing plate 31. The first magnetic member 91, the second magnetic member 92 and the third magnetic member 93 are magnetically attracted to each other one by one, and the fixing buckle 81 passes through the first fixing hole 82 and the second fixing hole 83 to complete the buckling. Through the magnetic attraction of the magnetic members and the buckling of the fixing buckle and the fixing holes, the bottom plate 1, the first pressing plate 31 and the second pressing plate 32 clamp the fabric between the three, and fix the positional relationship between the three, preventing the first pressing plate 31 and the second pressing plate 32 from being misaligned.

[0074] In some embodiments, the cushion plate portion 61 is an arc-shaped plate. The cushion plate portion 61 extends along the first direction, and the extension length of the cushion plate portion 61 in the first direction is greater than the arrangement length of the plurality of first sewing grooves 4 in the first direction; along the direction from the second side 12 to the first side 11, the first sewing grooves 4, the fixing buckle 81 and the cushion plate portion 61 are arranged in sequence. The cushion plate portion 61 is an arc-shaped plate, arranged adjacent to the first side 11, and the arc faces the first side 11. That is, on the bottom plate 1, the first sewing grooves 4, the fixing buckle 81 and the cushion plate portion 61 are arranged in sequence along the direction from the second side 12 to the first side 11. Since the extension length of the cushion plate portion 61 in the first direction is greater than the arrangement length of the plurality of first sewing grooves 4 in the first direction, the first pressing plate 31 and the second pressing plate 32 rotatably connected to the cushion plate portion 61 can be arranged at intervals with the first sewing grooves 4, so that each pleat formed by each pressing plate has a corresponding first sewing groove 4, ensuring the sewing of the pleat. Along the direction from the second side 12 to the first side 11, the first sewing grooves 4, the fixing buckle 81 and the cushion plate portion 61 are arranged in sequence, and the cushion plate portion 61 is arranged adjacent to the first side 11, so that the first sewing grooves 4 are located in the middle of the bottom plate 1, and the buckling structure of the fixing buckle and the fixing hole is located at the end of the pressing plate, which conforms to the operating habit of people and provides convenience for folding and sewing the pleats.

[0075] In some embodiments, in order to further improve the stability of the fabric and prevent the fabric from sliding during the pleat folding process and the sewing process, at least one of the bottom plate 1, the cover plate 2, the first pressing plate 31, and the second pressing plate 32 is provided with an anti-slip structure (not shown). Anti-slip structures of the same size are provided on the left and right sides of each sewing groove on the bottom plate 1 and the cover plate 2. The anti-slip structure can be an anti-slip strip. Between two adjacent first sewing grooves 4 on the bottom plate 1, a first sewing groove 4, an anti-slip structure, a first magnetic member 91, an anti-slip structure, and a first sewing groove 4 are sequentially arranged in the first direction; Anti-slip structures of the same size are provided on the front and back sides of the first pressing plate 31 and the second pressing plate 32. In the direction from the second side 12 to the first side 11, an anti-slip structure, a second magnetic member 92, and a first fixing hole 82 are sequentially arranged on the first pressing plate 31, and an anti-slip structure, a third magnetic member 93, and a second fixing hole 83 are sequentially arranged on the second pressing plate 32. During a pleat folding process, the fabric is first folded along one side of the first pressing plate 31, and then folded along the support strip side of the second pressing plate 32 to form a three-layer fabric, and a total of six contact surfaces are formed with the bottom plate 1, the cover plate 2, the first pressing plate 31, and the second pressing plate 32. In the case where the surface of the fabric is smoother, anti-slip structures are provided on the contact surfaces of the bottom plate 1, the cover plate 2, the first pressing plate 31, and the second pressing plate 32 with the fabric, which can enhance the friction between the bottom plate 1, the cover plate 2, the first pressing plate 31, and the second pressing plate 32 and the fabric, thereby effectively preventing the fabric from sliding during the pleat folding process and the sewing process, being beneficial to increasing the stability of the fabric and ensuring the sewing quality of the product.

[0076] Optionally, the anti-slip structure can be sandpaper or anti-slip paint, but is not limited thereto; the shape of the anti-slip structure can be strip-shaped, circular, or other shapes, but is not limited thereto.

[0077] In some other embodiments, the anti-slip structure can be combined with the magnetic member, that is, an anti-slip structure is provided on the surface of the magnetic member. Anti-slip structures are provided on the front and back sides of the first magnetic member 91 on the bottom plate 1, the second magnetic member 92 on the first pressing plate 31, and the third magnetic member 93 on the second pressing plate 32. Taking the first mounting hole, the second mounting hole, and the third mounting hole as circular holes of the same shape and size, the first magnetic member 91, the second magnetic member 92, and the third magnetic member 93 as cylindrical magnets of the same shape and size, the radius of the cylindrical magnet being the same as the radius of the cylindrical hole, and the anti-slip structure being sandpaper as an example. The sandpaper is pasted on the front and back sides of the cylindrical magnet, and then the cylindrical magnet is encapsulated in each mounting hole. During the folding process of the pleat, when pressing the first pressing plate 31, the second pressing plate 32, and the cover plate 2, the fabric can be further fixed, and at the same time, the surface of the fabric will not be damaged. At the same time, combining the anti-slip structure and the magnetic member is beneficial to further saving the template space, enabling the magnetic member to be designed larger, thereby providing a stronger fixing ability between the fabric and the pressing plate.

[0078] Further, both the front and back sides of the first magnetic member 91, the second magnetic member 92 of the first pressing plate 31, and the third magnetic member 93 of the second pressing plate 32 may be smooth surfaces or may be mutually cooperating concave and convex surfaces, but are not limited thereto. In the case where the anti-slip structure can be combined with the magnetic member and the surfaces of the magnetic members are mutually cooperating concave and convex surfaces, the anti-slip ability of the fabric can be enhanced, and at the same time, the dislocation of the pressing plates can be further prevented.

[0079] In some embodiments, the support bar may be a fishbone or other elastic soft comb-tooth-like structure. The support bar 7 protrudes on one side of the second pressing plate 32, and the protruding width is equal to the width of the first sewing groove 4. The support bar 7 extends along the length direction of the second pressing plate 32, and the length of the support bar 7 is adapted to the length of the first sewing groove 4. Figure 5 Structural schematic diagram of the second pressing plate provided by the embodiment of the present application, as Figure 5 shown, the right side of the second pressing plate 32 is in the right direction of the paper surface. The support bar 7 is arranged on the right side of the second pressing plate 32 and is located in the middle of the right side of the second pressing plate 32. The support bar 7 is a soft and elastic comb-tooth-like structure. During the sewing process of the fabric pleats, the support bar 7 is used to protrude the fabric. Since the protruding width of the support bar 7 is equal to or approximately equal to the width of the first sewing groove 4 and the length is adapted to the length of the first sewing groove 4, the fabric can be protruded between the first sewing groove 4 and the second sewing groove 5, facilitating the sewing of the fabric. At the same time, since the support bar 7 is a soft and elastic comb-tooth-like structure, the fabric can be directly taken out in the direction from the first side 11 to the second side 12 after the pleats are sewn. The teeth of the support bar 7 will bend along the taking-out direction when the fabric is taken out and return to the original state after taking out, which can avoid the bending and damage of the support bar 7 caused by taking out the fabric multiple times.

[0080] In the above embodiments, in order to ensure that the pleat sewing template has the function of pleat folding, further improve the portability of the template, and reduce the production cost of template manufacturing, the materials of the bottom plate 1, the cover plate 2, the first pressing plate 31, and the second pressing plate 32 are all transparent polyvinyl chloride (PVC) plates. Among them, the thickness of the bottom plate 1 and the cover plate 2 is d1, where 1 mm ≤ d1 ≤ 2 mm, and the thickness of the first pressing plate 31 and the second pressing plate 32 is d2, where 0.5 mm ≤ d2 ≤ 1 mm. By using transparent PVC plates to make the pleat sewing template 100, it is not only easy to process, can quickly and accurately produce a large number of unified templates to meet the needs of large-scale standardized production, but also can design more templates of different specifications to meet personalized needs. Moreover, the cost of the PVC material itself is relatively low, which can effectively reduce the production cost. At the same time, because the PVC plate is also transparent, the pleat shape can be clearly seen during the pleat folding process, reducing rework caused by pleat folding mistakes. In addition, setting the thickness of the bottom plate 1 and the cover plate 2 between 1 mm and 2 mm, and setting the thickness of the first pressing plate 31 and the second pressing plate 32 between 0.5 mm and 1 mm, can reduce the weight of the pleat sewing template 100. While ensuring the pleat folding quality, it improves the portability of the pleat sewing template 100, enabling workers to complete the pleat folding of multiple templates and then take them to sew at one time, which is conducive to reducing repetitive labor and improving production efficiency.

[0081] Exemplarily, the bottom plate 1 and the cover plate 2 are made of transparent PVC flat plates. The bottom plate 1 and the cover plate 2 are both transparent PVC flat plates with a length of 100 cm, a width of 80 cm, and a thickness of 1 mm. On the main board part 62 of the bottom plate 1, there are 9 first sewing grooves 4 with a length of 20 cm and a width of 3 mm, 10 cylindrical protruding fixing buttons 81, and 20 first mounting holes with a diameter of 5 mm and a thickness of 1 mm. The cushion part 61 of the bottom plate 1 is made of 2 layers of arc-shaped PVC plates with a thickness of 0.5 mm. On the cover plate 2, there are 9 second sewing grooves 5 with a length of 20 cm and a width of 3 mm. When the cover plate 2 is rotated and overlapped on the bottom plate 1, each second sewing groove 5 communicates with the corresponding first sewing groove 4 respectively.

[0082] The first pressing plate 31 and the second pressing plate 32 are made of transparent PVC flat plates. Both the first pressing plate 31 and the second pressing plate 32 are transparent PVC flat plates with a length of 30 cm, a width of 4 cm, and a thickness of 0.5 mm. There is a first fixing hole 82 with a diameter of 3 mm and a thickness of 0.5 mm and two second mounting holes with a diameter of 5 mm and a thickness of 0.5 mm on the first pressing plate 31. There is a second fixing hole 83 with a diameter of 3 mm and a thickness of 0.5 mm and two third mounting holes with a diameter of 5 mm and a thickness of 0.5 mm on the second pressing plate 32. And a fishbone (i.e., the support bar 7) is pasted in the middle of the right side of the second pressing plate 32. The length of the fishbone is 15 cm and the protruding width is 3 mm.

[0083] In each of the first mounting hole, the second mounting hole, and the third mounting hole, a first magnetic member 91, a second magnetic member 92, and a third magnetic member 93 with a diameter of 5 mm and a thickness of 1 mm are respectively encapsulated with transparent tape.

[0084] Please refer to Figure 6 , Figure 6 which is a schematic diagram of the sewing machine provided by the embodiment of the present application. The embodiment of the present application also provides a sewing machine 200. The sewing machine 200 includes a machine table 201, a sewing needle 202 disposed on the machine table, and a pleat sewing template 100 as described in any one of the above embodiments. The pleat sewing template 100 is disposed on the machine table 201, and the sewing needle 202 is configured to sew the fabric in the pleat sewing template 100. As Figure 6 shown, the pleat sewing template 100 is laid flat on the machine table 201 of the sewing machine 200, and the sewing needle 202 of the sewing machine 200 is aligned with the sewing groove of the pleat sewing template 100. After the pleats of the fabric are folded using the pleat sewing template 100, the pleat sewing template 100 is fixed to the machine table 201 of the sewing machine 200. After the sewing needle 202 is aligned with the sewing groove of the pleat sewing template 100, sewing can be started. During the sewing process, due to the tight buckling relationship between the fixing buckle 81 and the first fixing hole 82 and the second fixing hole 83, while clamping the fabric to prevent the fabric from sliding, the misalignment of the first pressing plate 31 and the second pressing plate 32 can be avoided, which is beneficial to improving the stability of the pressing plate during the pleat folding process and the sewing process. Using the sewing machine 200 to complete the sewing of the pleats on the pleat sewing template 100 can ensure that the stitching of the pleats is neat and tidy, which is beneficial to improving the sewing quality.

[0085] Optionally, the sewing machine 200 can be configured with one sewing needle, or can be configured with multiple sewing needles corresponding to the number of sewing grooves on the pleat sewing template, but not limited thereto. By setting multiple sewing needles corresponding to the number of sewing grooves on the pleat sewing template on the sewing machine 200, during the process of sewing the pleats, all the pleats of the pleat sewing template 100 can be sewn at one time, which can further reduce the repeated steps and improve the production efficiency.

[0086] When using the sewing machine disclosed in the embodiments of the present utility model, first unfold the cover plate 2 of the pleat sewing template 100 and all the first pressing plates 31 and the second pressing plates 32. After checking that all the components on the pleat sewing template 100 are undamaged, take a fan-shaped fabric for pleat folding and lay it flat on the bottom plate 1. After ensuring that the fabric is closely attached to the anti-slip structure on the bottom plate 1, close the first pressing plate 31 of No. 1 and the second pressing plate 32 of No. 1, ensure that the fixing buckle 81 of No. 1 and the first fixing hole 82 of No. 1 and the second fixing hole 83 of No. 1 are closely buckled, and the first magnetic member 91, the second magnetic member 92 and the third magnetic member 93 of No. 1 are magnetically attracted to each other, so that one side of the fabric is fixed on the template.

[0087] Subsequently, press the second first pressing plate 31 so that the fixing buckle 81 of No. 2 passes through the first fixing hole 82 of No. 2, and the first magnetic member 91 of No. 2 and the second magnetic member 92 of No. 2 are magnetically attracted to each other. Then turn the fabric from the left side to the right side along the second first pressing plate 31 so that the fabric is closely attached to the upper surface of the second first pressing plate 31. Then fold it from the right side of the fishbone (i.e., the support bar 7) of the second second pressing plate 32 to the left side so that the fabric is also closely attached to the second second pressing plate 32. Finally, flatten the remaining fabric on the pleat sewing template 100 to complete the folding of one pleat.

[0088] And so on. After repeating the above steps to complete the pleat folding of other pressing plates in turn, check the folding quality of all the pleats, then cover the cover plate 2, press the pleat sewing template 100 tightly, place it on the machine table 201 of the sewing machine 200, align the sewing groove of the pleat sewing template 100 with the sewing needle 202, fix the pleat sewing template 100, start the sewing machine 200, and complete the sewing of the pleats in the pleat sewing template 100. During the pleat folding process and the sewing process. By adopting various fixing measures such as the buckling structure of the fixing buckle and the fixing hole, the magnetic member, and the anti-slip structure, the stability of the fabric and the pressing plate can be effectively improved, and the occurrence of fabric sliding and pressing plate misalignment can be further reduced, which is beneficial to reducing the defective rate of the pleats and ensuring the sewing quality.
