[0002] Pleats refer to wrinkles and folds made on certain parts of clothing according to the needs of the human body or style. They are widely used in clothing design and can be used on hems, cuffs, necklines and other parts to add a three-dimensional and layered feel to clothing, making it more beautiful and fashionable. At present, when sewing pleats, workers first mark the position of the pleats on the fabric, then use an iron to iron out the creases, and use a machine to fix the creases, and finally sew the pleats onto the clothing. The ironing and sewing process places high demands on the workers' ironing and sewing skills.

[0003] In order to improve the breathability of clothing while ensuring the aesthetics of clothing, some existing clothing is provided with ventilation holes and pleats are sewn at the ventilation holes.

[0049] Embodiment 1

[0050] like Figures 1 to 6 As shown, the present embodiment provides a pleat sewing tool for breathable fabrics, in which pleats are formed while sewing the knots 103 at the ventilation holes 1011. The operation is simple and quick, which improves the efficiency of clothing production and reduces the requirements on the operating skills of the staff.

[0051] See also Figure 1 , Figure 2 and Figure 3 The breathable fabric 100 includes a first sheet 101 and two second sheets 102. The two second sheets 102 are disposed on both sides of the first sheet 101. The first sheet 101 is provided with a plurality of breathable holes 1011. The breathable holes 1011 extend in the direction ( Figure 2 The two ends of the pleat sewing tool for breathable fabrics are provided with tacking positions. The pleat sewing tool for breathable fabrics comprises a base plate 1, a clamping plate assembly 2 and a cover plate 3. The clamping plate assembly 2 comprises a first clamping plate 21 and a second clamping plate 22 which are both rotatably arranged on the base plate 1. The clamping plate assembly 2 has a sewing position and an installation position. In the sewing position, the clamping plate assembly 2 is stacked with the base plate 1, the first clamping plate 21 is spliced ​​with the second clamping plate 22, and a first positioning hole 23 corresponding to a plurality of tacking positions is formed at the splicing position of the first clamping plate 21 and the second clamping plate 22; in the installation position, the first clamping plate 21 and the second clamping plate 22 are arranged at intervals; the cover plate 3 is rotatably arranged on the base plate 1, and a second positioning hole 31 corresponding to a plurality of first positioning holes 23 is arranged on the cover plate 3, and in the sewing position, the cover plate 3 is stacked on the top of the clamping plate assembly 2.

[0052] The pleat sewing tool for breathable fabrics provided in this embodiment is arranged at an installation position with the first clamping plate 21 and the second clamping plate 22 arranged at intervals, the first sheet 101 of the breathable fabric 100 is laid flat on the bottom plate 1 between the first clamping plate 21 and the second clamping plate 22, and the two second sheets 102 can be laid flat on the first clamping plate 21 and the second clamping plate 22 respectively; the two second sheets 102 are folded so that parts of the two second sheets 102 overlap with the first sheet 101, and the overlapped parts form The pleats are formed, thereby realizing folding pleats at the vent hole 1011; then the first clamping plate 21 and the second clamping plate 22 are rotated to be spliced ​​with each other and overlapped with the bottom plate 1, and the pleats formed at this time are clamped by the clamping plate assembly 2 and the bottom plate 1, realizing the fixation of the pleats; after the cover plate 3 is rotated to overlap with the clamping plate assembly 2, the cover plate 3 can press the clamping plate assembly 2 and the breathable fabric 100 against the bottom plate 1, effectively preventing the pleats from deforming during the sewing process, and ensuring the accuracy of sewing. When in the sewing position, the first positioning hole 23 corresponding to the tacking position is formed at the splicing of the first clamping plate 21 and the second clamping plate 22, so the part of the second sheet 102 that is not overlapped with the first sheet 101 can extend from the splicing of the first clamping plate 21 and the second clamping plate 22 to the side of the clamping plate assembly 2 away from the bottom plate 1, that is, the pleats can only be formed at the vent hole 1011, so that the clothing made of the breathable fabric 100 can be more beautiful. During the sewing process, the first positioning hole 23 and the second positioning hole 31 can jointly form a through hole that penetrates the thickness direction of the breathable fabric 100, so that the sewing equipment can accurately sew the bar knot 103 at the bar knot position. The bar knot 103 separates a plurality of air holes 1011, and can reinforce the breathable fabric 100. The sewn bar knot 103 also sews the second sheet 102 and the first sheet 101 together, and divides the pleats into multiple sections to ensure the firmness of the pleats. Compared with the existing process of sewing pleats on the breathable fabric 100, when sewing pleats using the pleat sewing tool of this embodiment, pleats are formed while sewing the bar knot 103 at the air hole 1011, without the need for separate steps, and the operation is simple and fast, which improves the efficiency of clothing production and reduces the requirements for the operating skills of the staff.

[0053] For example, see Figure 2 There are four ventilation holes 1011, five tacking positions, and the pleats are divided into six sections.

[0054] Exemplarily, the breathable fabric 100 can be used in any part of a garment that requires ventilation, such as the front, back, and sleeves.

[0055] Exemplarily, the cover plate 3, the splint assembly 2 and the base plate 1 are all made of transparent plastic such as PVC, so that the staff can observe the position of the breathable fabric 100 through the cover plate 3 and the splint assembly 2, so that the staff can always observe the pleats and the knots 103 during the sewing process.

[0056] In this embodiment, refer to Figure 1 and Figure 3 A plurality of grooves 231 are provided on the first splint 21 and the second splint 22, and the plurality of grooves 231 correspond to the plurality of tacking positions one by one. When in the sewing position, the grooves 231 are located on the side where the first splint 21 and the second splint 22 face each other, and the grooves 231 on the first splint 21 and the grooves 231 on the second splint 22 are arranged to form a first positioning hole 23.

[0057] Optionally, see Figure 1 , Figure 2 and Figure 4 The pleat sewing tool for breathable fabrics also includes a limiting plate 4, which can be detachably arranged between the base plate 1 and the clamping plate assembly 2. When the limiting plate 4 is located between the base plate 1 and the clamping plate assembly 2, the limiting plate 4 is overlapped at the joint of the first clamping plate 21 and the second clamping plate 22. After the first sheet 101 is laid flat on the base plate 1, the limiting plate 4 is placed on the air hole 1011 of the first sheet 101. The limiting plate 4 can press the first sheet 101 against the base plate 1. On the one hand, it can prevent the first sheet 101 from moving when the second sheet 102 is folded, thereby affecting the accuracy of clothing production. On the other hand, it also enables the second sheet 102 to be folded along the side of the limiting plate 4, which is convenient for the staff to fold the second sheet 102 and ensures the accuracy of the folding position, thereby improving the accuracy of the formed pleats. When the cover plate 3 is rotated to the sewing position, the limiting plate 4 is pulled out from between the base plate 1 and the clamping plate assembly 2 to prevent the limiting plate 4 from affecting the sewing of the breathable fabric 100.

[0058] Further, see Figure 2 and Figure 4 The limiting plate 4 is provided with a plurality of first identification parts 41, and the plurality of first identification parts 41 correspond to the plurality of ventilation holes 1011. When the first sheet 101 is laid flat on the bottom plate 1, the staff can adjust the final position of the limiting plate 4 by the relative position of the first identification parts 41 and the ventilation holes 1011.

[0059] In this embodiment, refer to Figure 2 and Figure 4 A mounting groove 11 is provided on the bottom plate 1, and the limiting plate 4 can be detachably embedded in the mounting groove 11, so that the limiting plate 4 can be accurately placed at the air hole 1011 and will not move to ensure that the formed pleats are accurately located at the air hole 1011.

[0060] Exemplarily, the length of the limiting plate 4 along the extension direction of the air vent 1011 is greater than the length of the cover plate 3 and the clamping plate assembly 2, so that the staff can easily pull out the limiting plate 4; a pleat is formed between each second piece 102 and the first piece 101, so the width of the limiting plate 4 should not be less than twice the width of the pleat.

[0061] In an alternative embodiment, see Figure 2 and Figure 3 The first clamping plate 21 is provided with a first positioning line 241, and the second clamping plate 22 is provided with a second positioning line 242. When sewing, the first positioning line 241 and the second positioning line 242 form a contour line 24 that is adapted to a part of the outer contour of the breathable fabric 100. For some breathable fabrics 100 with darker colors, the contour line 24 can help the staff determine whether the position of the breathable fabric 100 on the pleat sewing tool is accurate, and can also help the staff adjust the position of the breathable fabric 100 to ensure the accuracy of clothing production.

[0062] Exemplarily, the breathable fabric 100 is used on the back of a garment, and the contour line 24 conforms to the contour of the collar and the contour of the hem of the garment.

[0063] In another alternative embodiment, see Figure 2 The bottom plate 1 is provided with a third positioning line 12 adapted to the outer contour of the breathable fabric 100. When the breathable fabric 100 is laid flat on the bottom plate 1, the staff can adjust the position of the breathable fabric 100 according to the third positioning line 12, so that the breathable fabric 100 can be accurately placed on the pleat sewing tooling to ensure the accuracy of garment production.

[0064] Exemplarily, the breathable fabric 100 is used on the back of a garment, and the third positioning line 12 is adapted to the contour of the entire back of the garment.

[0065] In another alternative embodiment, see Figure 2 and Figure 5 The cover plate 3 is provided with a fourth positioning line 32 adapted to a part of the outer contour of the breathable fabric 100. During the sewing process, the staff can determine whether the breathable fabric 100 moves or deforms by constantly observing the position between the outer contour of the breathable fabric 100 and the fourth positioning line 32, thereby further ensuring the accuracy of garment production.

[0066] Exemplarily, the breathable fabric 100 is used on the back of a garment, and the fourth positioning line 32 is adapted to the contours of the collar and the hem of the garment.

[0067] Optionally, see Figure 2 The bottom plate 1 is provided with a plurality of second identification parts (not shown in the figure), and the plurality of second identification parts correspond to the plurality of ventilation holes 1011. When the first sheet 101 is laid flat on the bottom plate 1, the bar knot 103 has not been tied yet, and the bar knot position cannot be displayed. At this time, the staff can accurately place the first sheet 101 on the bottom plate 1 according to the second identification part to ensure the accuracy of clothing production.

[0068] Further, see Figure 1 , Figure 2 and Figure 5 The clamping plate assembly 2 and the cover plate 3 are provided with third identification parts 33 corresponding to the plurality of ventilation holes 1011, so that the position of the breathable fabric 100 can be calibrated according to the position of the third identification part 33 in each process of sewing the pleat tooling.

[0069] Optionally, see Figure 3 and Figure 5 The first plywood 21 and the second plywood 22 are both provided with a horsetail lining 25. When in the sewing position, the horsetail lining 25 is located on the side of the first plywood 21 and the second plywood 22 facing each other, that is, the horsetail lining 25 is located at the joint of the first plywood 21 and the second plywood 22. On the one hand, the horsetail lining 25 has a certain thickness and elasticity, is relatively rough and has good stiffness, so during the sewing process, the horsetail lining 25 can increase the friction between it and the second piece 102 passing through the joint of the first splint 21 and the second splint 22, and plays a role in fixing the second piece 102 to prevent the second piece 102 from sliding, ensuring that the formed pleats will not be deformed, and further ensuring the accuracy of clothing production; on the other hand, the horsetail lining 25 is located at the joint of the first splint 21 and the second splint 22, so that the first positioning hole 23 is formed between the horsetail lining 25 of the first splint 21 and the horsetail lining 25 of the second splint 22. Because there are multiple burrs on the horsetail lining 25, the sewing thread of the sewed knot 103 in the first positioning hole 23 will not break, thereby improving the beauty of the sewing thread.

[0070] For example, see Figure 2 and Figure 3 The horsetail lining 25 extends along the extension direction of the ventilation holes 1011 , and the length of the horsetail lining 25 is not less than the total length of the plurality of ventilation holes 1011 to ensure that the plurality of first positioning holes 23 can all be located between the horsetail linings 25 .

[0071] Optionally, see Figure 3 and Figure 5 The pleat sewing tool for breathable fabrics also includes a first flexible connector 51, a second flexible connector 52 and a third flexible connector 53. One end of the first flexible connector 51 is bonded to the bottom plate 1, and the other end is bonded to the first clamping plate 21. One end of the second flexible connector 52 is bonded to the bottom plate 1, and the other end is bonded to the second clamping plate 22. One end of the third flexible connector 53 is bonded to the bottom plate 1, and the other end is bonded to the cover plate 3. The first flexible connector 51, the second flexible connector 52 and the third flexible connector 53 are made of flexible materials, so that when rotating, the two ends of the first flexible connector 51, the two ends of the second flexible connector 52 and the two ends of the third flexible connector 53 can all rotate relative to each other, thereby realizing the rotation connection between the first clamping plate 21, the second clamping plate 22 and the cover plate 3 and the bottom plate 1.

[0072] In this embodiment, refer to Figure 3 and Figure 5 The third flexible connector 53 is perpendicular to the first flexible connector 51 and the second flexible connector 52 to prevent the rotation of the clamping plate assembly 2 from affecting the rotation of the cover plate 3. Figure 3 In the orientation, the first flexible connector 51 and the second flexible connector 52 are both along the extension direction of the vent hole 1011 ( Figure 3 The first clamping plate 21 and the second clamping plate 22 are extended in the Y direction so that the first clamping plate 21 and the second clamping plate 22 can rotate around the Y direction. Figure 5 In the orientation, the third flexible connector 53 is arranged along the width direction of the air vent 1011 ( Figure 5 The cover plate 3 extends in the X direction, so that the cover plate 3 rotates around the X direction, and the rotation of the cover plate 3 and the clamping plate assembly 2 does not affect each other.

[0073] Exemplarily, the first flexible connector 51 , the second flexible connector 52 and the third flexible connector 53 are all made of adhesive tape.

[0074] Embodiment 2
