Description

Technical Field

[0001] This application belongs to the field of garment processing technology, specifically relating to a workwear for stitching dots on the flap of a chest pocket. Background Technology

[0002] Military uniforms, especially the breast pockets of the jackets, typically require flaps. These flaps prevent the top of the breast pocket from collapsing and developing frayed edges, and also enhance the concealment of items inside. There are specific requirements for the placement of the breast pocket flaps; they must be positioned symmetrically on both sides of the jacket to improve both the aesthetics and practicality of the garment.

[0003] In existing technology, the position of the bag flap is determined manually by marking dots on the fabric to be sewn. These dots are drawn with chalk using measurements, and the bag flap fabric is then placed on the fabric according to the marked dots, folded along these lines, and sewn. Manual measurement relies on the skill level of the employee, is prone to errors, requires multiple measurements, is cumbersome, and has low efficiency. Furthermore, the loose texture and weak adhesion of the chalk cause the dots to smudge and disappear, requiring repeated re-marking, further complicating the process and making it unsuitable for mass production. Utility Model Content

[0004] This application provides a stitching fixture for marking dots on the flap of a breast pocket, which aims to solve the technical problems in the prior art where using chalk to mark dots at the position of the hidden line on the flap is prone to errors, affecting the sewing quality, and the chalk is easy to fall off, requiring repeated marking and reducing the marking efficiency.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: A workwear for sewing dots on the flap of a breast pocket is provided, comprising: The workbench has an upper surface divided into a dotting area and a sewing area along its length, and the sewing area is equipped with the main body of a sewing machine; A bracket is provided on the dotted area; A laser dotting device is installed on the top of the bracket, and the laser dot of the laser dotting device is located on the dark line of the bag cover; The upper pressure plate is slidably mounted on the worktable and can move up and down in the vertical direction; and The lower clamping plate is slidably disposed on the worktable. The lower clamping plate is used to place the fabric. The upper pressure plate can descend and fit against the lower clamping plate to clamp the fabric and bag cap, and move the fabric and bag cap from the dotting area to the sewing area for sewing.

[0006] In one possible implementation, there are multiple laser dotting devices, which are spaced apart along the axial direction of the dark line on the bag cover. The distance between the laser sources of the two outermost laser dotting devices is equal to the length of the dark line on the bag cover.

[0007] In one possible implementation, the breast pocket flap dotting sewing fixture also includes a dotting pen, which is vertically and vertically connected to the bracket, and the bottom of the dotting pen forms a dotting part for dotting the fabric.

[0008] In one possible implementation, the chest pocket flap dotting sewing fixture further includes a telescopic drive component, which is mounted on the bracket. The bottom of the telescopic drive component forms a height-adjustable telescopic end, and the dotting pen is connected to the telescopic end.

[0009] In one possible implementation, the support includes a vertical rod and a horizontal rod, the vertical rod being disposed on one side of the dotting area, a first end of the horizontal rod being connected to the top of the vertical rod, a second end being located above the dotting area, and the laser dotting device being disposed at the second end of the horizontal rod.

[0010] In one possible implementation, the upper pressure plate is provided with an upper sewing opening, and the lower clamping plate is provided with a lower sewing opening corresponding to the upper sewing opening. The upper sewing opening and the lower sewing opening are connected, and the sewing machine body moves the needle within the upper sewing opening.

[0011] In one possible implementation, the breast pocket flap dotting sewing fixture further includes a moving component, the moving component comprising: The first sliding table has its two ends located at the dotting area and the sewing area respectively, and the length direction of the first sliding table is parallel to the length direction of the worktable. The first sliding table moves along the width direction of the worktable, and a first slider is slidably provided on the side of the first sliding table. A second sliding platform is connected to the first slider. The length direction of the second sliding platform is parallel to the length direction of the worktable. A second slider that slides along the length direction of the second sliding platform is provided on its side. A lifting drive component is connected to the side of the second slider, and a lifting end is formed at the bottom of the lifting drive component. The lifting end is connected to the upper pressure plate.

[0012] In one possible implementation, the upper pressure plate is further provided with a badge hole, which conforms to the shape of the badge.

[0013] In one possible implementation, the upper pressure plate has a mounting opening in the middle, and a mounting plate is detachably mounted in the mounting opening. The badge hole is located in the middle of the mounting plate.

[0014] In one possible implementation, the lower clamp is provided with a limiting block that can fit against the neckline edge of the fabric to limit the maximum size of the fabric.

[0015] The breast pocket flap marking and sewing fixture provided in this application, compared with existing technologies, uses a laser dotting device to emit a laser. The fabric with the flap is placed on the lower clamping plate, and precise positioning and marking are achieved by utilizing the linear correspondence between the laser dots and the dark lines of the flap. The flap is manually folded over, then the upper pressure plate descends and fits against the lower clamping plate, holding the fabric and flap in place. Finally, the upper and lower pressure plates, holding the fabric and flap, move from the dotting area to the sewing area, where the sewing machine completes the sewing. By replacing manual chalk measurement and marking with a laser dotting device, laser positioning is precise, avoiding errors from manual operation. Laser marking does not require physical contact with the fabric, thus avoiding... Because the dots may become blurred due to pressing and friction, they can remain clear over a long period of time, ensuring that the positioning benchmark of each pocket flap is consistent from the source, ultimately achieving the height symmetry of the pocket flaps on both sides of the garment. Employees fold the pocket flaps according to the dots marked by the laser dotting device, and then the upper pressure plate and lower clamping plate hold them directly to the sewing area for sewing. This reduces the steps of repeated manual movement and positioning, simplifies the process, shortens the time, improves dotting and sewing efficiency, and is suitable for mass production. Moreover, the laser markings are clear and stable, and will not smudge or disappear like chalk, which can continuously ensure positioning accuracy, thereby improving the symmetry of the pocket flaps on both sides of the garment and enhancing the aesthetics and practicality of the clothing.

[0025] Please refer to the following: Figures 1 to 10 The following describes the stitching fixture for the chest pocket flap provided in this application. The stitching fixture for the chest pocket flap includes a worktable 1, a support 2, a laser dotting device 3, an upper pressure plate 4, and a lower clamping plate 5. The upper surface of the worktable 1 is divided into a dotting area and a sewing area along its length. The sewing area is equipped with a sewing machine body 11. The support 2 is located on the dotting area. The laser dotting device 3 is installed on the top of the support 2, and the laser dot of the laser dotting device 3 is located on the dark line of the flap 82. The upper pressure plate 4 is slidably located on the worktable 1 and can be raised and lowered in the vertical direction. The lower clamping plate 5 is slidably located on the worktable 1 and is used to place the fabric 8. The upper pressure plate 4 can be lowered to fit against the lower clamping plate 5 to clamp the fabric 8 and the flap 82, and to move the fabric 8 and the flap 82 from the dotting area to the sewing area for sewing.

[0026] See Figures 8 to 10The working process of this application is as follows: the laser dotting device 3 emits a laser, and the fabric 8 with the bag cover 82 is placed on the lower clamping plate 5. The laser dots are precisely positioned and dotted by the straight line correspondence between the laser dots and the dark lines of the bag cover 82. Then, the bag cover 82 is manually flipped so that the bag cover 82 and the chest pocket 81 are attached. The upper pressure plate 4 is lowered and attached to the lower clamping plate 5 to hold the fabric 8 and the bag cover 82. Finally, the upper pressure plate 4 and the lower clamping plate 5 holding the fabric 8 and the bag cover 82 are moved from the dotting area to the sewing area, and the sewing is completed by the sewing machine body 11.

[0027] The chest pocket flap marking and sewing fixture provided in this embodiment, compared with the prior art, uses a laser dotting device 3 to replace manual chalk measurement and marking. Laser positioning is accurate, avoiding errors from manual operation. The laser marking does not require physical contact with the fabric 8, and the dots will not become blurred due to pressing or friction, and can remain clear for a long time. This ensures that the positioning benchmark of each pocket flap 82 is consistent from the source, ultimately achieving the height symmetry of the pocket flaps 82 on both sides of the garment. The employee folds the pocket flap 82 according to the dotting position of the laser dotting device 3, and then the upper pressure plate 4 and the lower clamping plate 5 hold it and move it directly to the sewing area for sewing. This reduces the steps of repeated manual movement and positioning, simplifies the process, shortens the time, improves the efficiency of dotting and sewing, and is suitable for mass production. Moreover, the laser marking is clear and stable, and will not smudge and disappear like chalk, which can continuously ensure positioning accuracy, thereby improving the symmetry of the pocket flaps 82 on both sides of the garment and enhancing the aesthetics and practicality of the garment.

[0028] In some embodiments, see Figures 1 to 4 Multiple laser dotting devices 3 are provided, arranged at intervals along the axial direction of the dark line of the bag cover 82. The distance between the laser sources of the two outermost laser dotting devices 3 is equal to the length of the dark line of the bag cover 82. The multiple laser dotting devices 3 are arranged at intervals along the axial direction of the dark line and cover the entire length of the dark line, which can achieve multi-point precise positioning of the bag cover 82 along the dark line, avoid local positioning deviations that cause the bag cover 82 to be skewed, and further improve the symmetry and accuracy of the bag cover 82 installation.

[0029] In some embodiments, see Figures 1 to 4 The workwear for marking the flap of the chest pocket also includes a marking pen 6, which is vertically and height-adjustable to the bracket 2. The bottom of the marking pen 6 forms a marking section for marking dots on the fabric 8. The vertically adjustable marking pen 6 can mark dots at the neckline of the garment. The marking marks make it easier for employees to align the fabric 8 with the fabric on the back, facilitating garment alignment and improving sewing convenience.

[0030] It should be noted that the dot pen 6 has a lifting and lowering setting, so employees do not need to find the dot position. The dot position of the dot pen 6 is the same on each piece of fabric 8, which makes it convenient for employees to quickly and effectively align the dots.

[0031] In some embodiments, see Figure 5 and Figure 6The stitching fixture for the chest pocket flap also includes a telescopic drive component 61, which is mounted on the bracket 2. The bottom of the telescopic drive component 61 forms a height-adjustable telescopic end, to which the stitching pen 6 is connected. The telescopic drive component 61 drives the stitching pen 6 to automatically rise and fall to make stitches, replacing manual operation and improving the automation and efficiency of stitching. Furthermore, under the control of the drive component, the stitching force and position are more stable and consistent, reducing the differences in manual stitching.

[0032] In practice, the telescopic drive component 61 is a cylinder, which quickly and effectively drives the dotting pen 6 to descend, so that the dotting part of the dotting pen 6 can effectively collide with the fabric 8, so that the fabric 8 is marked.

[0033] In some embodiments, see Figure 2 The support 2 includes a vertical rod 21 and a horizontal rod 22. The vertical rod 21 is located on one side of the dotting area. The first end of the horizontal rod 22 is connected to the top of the vertical rod 21, and the second end is located above the dotting area. The laser dot generator 3 is located at the second end of the horizontal rod 22. The support 2 structure, consisting of the vertical rod 21 and the horizontal rod 22, is simple and can stably support the laser dot generator 3, ensuring the stability of the laser emission angle and position, thereby guaranteeing dotting accuracy. The vertical rod 21 can support the horizontal rod 22, moving the laser dot generator 3 away from the worktable 1, avoiding the movement space of the upper pressure plate 4 and the lower clamping plate 5, while also facilitating the adjustment of the emission angle of the laser dot generator 3 by the employee, increasing operational convenience.

[0034] In some embodiments, see Figure 1 , Figure 7 and Figure 8 The upper pressure plate 4 has an upper sewing opening 41, and the lower clamping plate 5 has a lower sewing opening 51 corresponding to the upper sewing opening 41. The upper sewing opening 41 and the lower sewing opening 51 are connected. The laser dot of the laser dot generator 3 falls on the center line of the upper sewing opening 41 along its own length direction, and the sewing machine body 11 moves its needle within the upper sewing opening 41. The design of the upper sewing opening 41 and the lower sewing opening 51 being connected allows the sewing machine body 11 to move its needle accurately while holding the fabric 8 and the bag flap 82, improving the accuracy of sewing and the quality of the stitches.

[0035] In practice, the upper sewing opening 41 and the lower sewing opening 51 have the same shape.

[0036] In some embodiments, see Figures 1 to 4The chest pocket flap stitching fixture also includes a moving component 7, which includes a first sliding table 71, a second sliding table 72, and a lifting drive 73. The two ends of the first sliding table 71 are located in the stitching area and the sewing area, respectively, and the length direction of the first sliding table 71 is parallel to the length direction of the workbench 1. The first sliding table 71 moves along the width direction of the workbench 1, and a first slider is slidably provided on the side of the first sliding table 71. The second sliding table 72 is connected to the first slider, and the length direction of the second sliding table 72 is parallel to the length direction of the workbench 1. A second slider that slides along its own length direction is provided on the side of the second sliding table 72. The lifting drive 73 is connected to the side of the second slider, and the bottom of the lifting drive 73 forms a lifting end, which is connected to the upper pressure plate 4.

[0037] In practice, the second slider slides along the length of the second sliding table 72 to ensure that the clamping position of the upper pressure plate 4 accurately corresponds to the dot position. After the position is calibrated, the lifting end of the lifting drive component 73 moves, causing the upper pressure plate 4 to descend and fit tightly against the lower clamping plate 5, which holds the fabric 8 and the bag cover 82, thus completing the clamping and fixing of the fabric 8 and the bag cover 82. The first sliding table 71 moves along the width of the worktable 1 to adjust the overall lateral position. The first sliding table 71 and the second sliding table 72 slide together to smoothly transfer the upper pressure plate 4 and the lower clamping plate 5, which hold the fabric 8 and the bag cover 82, from the dot area to the bottom of the sewing machine body in the sewing area, providing a precisely positioned processing object for subsequent sewing processes.

[0038] The moving component 7 of this application, through the cooperation of the first sliding table 71 and the second sliding table 72, enables the upper pressure plate 4 to move flexibly and accurately in the plane. Combined with the lifting control of the lifting drive component 73, it can stably and accurately move the clamped fabric 8 and bag cover 82 from the dotting area to the sewing area, ensuring that the positions of the fabric 8 and bag cover 82 remain unchanged during the movement, further improving the accuracy and automation of the processing.

[0039] In some embodiments, see Figure 7 The upper pressure plate 4 also has badge holes 43, which conform to the shape of the badge. The badge holes 43, which conform to the shape of the badge, can position the badge while the bag cap 82 is being processed, so as to achieve precise sequential processing of the bag cap 82 and the badge. This eliminates the need for employees to find the badge installation position separately, increases work convenience, reduces work intensity, and meets the production needs of multiple processes combining the bag cap 82 and the badge.

[0040] In some embodiments, see Figure 7The upper pressure plate 4 has a mounting opening in the middle, and a mounting plate 42 is detachably mounted inside the mounting opening. The badge hole 43 is located in the middle of the mounting plate 42. The detachable mounting plate 42 allows the tooling to be adapted to the processing of badges of different styles and shapes by replacing the mounting plate 42 with different shaped badge holes 43, thereby improving the versatility and flexibility of the tooling.

[0041] In some embodiments, see Figure 2 The lower clamping plate 5 is equipped with a limiting block 52, which can fit against the neckline edge of the fabric 8 to limit the maximum size of the fabric 8. To avoid incorrect pattern, the limiting block 52 can be installed according to the pattern to assist the laser dotting device 3 in positioning the fabric 8 and increase the convenience of placing the fabric 8.

[0042] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
