[0002] In the garment manufacturing industry, breast pocket strips are a common accessory with extremely high processing requirements. The traditional sewing process usually uses a single-sided flat template or simple clamps: first, the breast pocket strip is placed face up on an ordinary flat board, and then roughly positioned by manual marking or fixing blocks before sewing; then the clamps are completely released, the workpiece is turned over and repositioned for secondary reinforcement or decorative stitching.

[0003] The aforementioned devices have the following drawbacks: existing templates are mostly integrally milled, with the cutout trajectory corresponding one-to-one with the style. When changing styles, the entire device needs to be disassembled and recalibrated, with a mold change time of 5-10 minutes, which seriously affects small-batch, multi-variety production. Furthermore, there is no rigid constraint in both the X and Y directions when manually marking lines or positioning blocks, and the cumulative error often reaches ±2 mm. Realigning after flipping the device makes it easier to produce secondary deviations, resulting in seam offset, inconsistent bag strip lengths, and a high defect rate. Therefore, a negative pressure chest bag strip sewing template is proposed to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 1 - Figure 2 This utility model provides an embodiment of a negative pressure chest pocket strip sewing template, comprising a main board 1. The main board 1 serves as the structural base of the entire negative pressure chest pocket strip sewing template, used to support, position, and integrate the sewing components 4 and the flipping strip 2, ensuring the overall rigidity of the template and its installation reference on the sewing equipment. The flipping strip 2 is fixedly installed on the right surface of the main board 1, and the flipping strip 2 flexibly connects the main board 1 and the secondary board 3, allowing the secondary board 3 to rotate 180° relative to the main board 1, thereby enabling rapid switching and avoidance of the front and back sewing positions of the chest pocket strip. The secondary board 3 is fixedly installed at the right end of the flipping strip 2. Together with the main board 1, a double-layer clamping space is formed for placing the chest pocket strip fabric and the negative pressure adsorption channel. The flipping action enables the rapid flipping and secondary positioning of the front and back sides of the fabric. The upper surface of the secondary board 3 is provided with an auxiliary component 5. The auxiliary component 5 is installed on the upper surface of the secondary board 3 to provide auxiliary pressure and avoidance space during the reverse side sewing stage of the chest pocket strip, ensuring that the seam is flat and wrinkle-free. The upper surface of the main board 1 is provided with a sewing component 4. The sewing component 4 is integrated into the modular unit on the upper surface of the main board 1 and is used for precise sewing trajectory positioning, length adjustment and replaceable sewing template installation of the chest pocket strip.

[0019] Reference Figure 2 - Figure 4The sewing component 4 includes a sewing template 41, which is detachably connected to the inner wall of the mounting groove 44. The sewing template 41 is a replaceable core component, and its hollow trajectory determines the direction of the stitching of the chest pocket strip. It is fixed to the main board 1 by magnetic attraction, enabling quick switching between different styles of chest pocket strips. The upper surface of the main board 1 has a mounting groove 44. The recessed space formed by the mounting groove 44 and the upper surface of the main board 1 is used to accommodate and limit the sewing template 41, while also providing an area for the placement of magnetic strips 46. Multiple sets of mounting grooves 45 are provided at the top corner of the inner wall of the mounting groove 44. 5. In conjunction with the mounting column 43, the sewing template 41 can be quickly and precisely positioned by insertion and removal, preventing rotation or displacement. Multiple sets of magnetic strips 46 are fixedly installed on the upper surface of the inner wall of the mounting groove 44. A magnetic plate is embedded in the rear surface of the sewing template 41. The rear surface of the sewing template 41 is magnetically connected to the upper surface of the magnetic strips 46. The magnetic strips 46 magnetically attract the magnetic plate on the back of the sewing template 41, realizing tool-free quick loading and unloading and stable clamping of the template. A fixing strip 42 is fixedly installed on the left end of the upper surface of the sewing template 41, forming a rigid pressure on the left end of the upper surface of the sewing template 41. To prevent lateral displacement of the template due to vibration during sewing, multiple sets of mounting posts 43 are fixedly installed at the top corner of the rear surface of the sewing template 41. The mounting posts 43 and the mounting groove 45 form a precise positioning pair, ensuring the repeatability of the sewing template 41 in the X and Y directions. The outer wall of the mounting posts 43 is inserted into the inner wall of the mounting groove 45. The sewing assembly 4 also includes a slide rail 48, which provides linear guidance for the slider 481, ensuring that the positioning buckle 49 moves linearly along the sewing direction and avoiding skewing. The slide rail 48 is located on the right side of the main board 1 near the mounting groove 44. A slider 481 is slidably connected to the inner wall of the slide rail 48. The slider 481 slides within the slide rail 48 to support and drive the positioning buckle 49 to achieve stepless adjustment of the sewing end point. The positioning buckle 49 is installed on the upper surface of the slider 481. The positioning buckle 49 is installed on the upper surface of the slider 481 to abut the end of the breast pocket strip, providing a sewing length limit and repeat positioning reference. A telescopic ruler 47 is fixedly installed on the left surface of the slide rail 48. The telescopic ruler 47 is installed on the left side of the slide rail 48 to measure and indicate the movement distance of the slider 481 in real time, thereby accurately adjusting the sewing stop point of the positioning buckle 49.

[0020] Reference Figure 2 - Figure 4The auxiliary component 5 includes an auxiliary pressure strip 51, which is detachably connected to the inner wall groove of the mounting strip 52. The auxiliary pressure strip 51 flexibly presses the edge of the chest pocket strip with a trapezoidal outline and rounded apex structure to prevent fabric slippage and reduce indentations. The outer surface of the auxiliary pressure strip 51 is set as a trapezoidal structure, and the apex of the outer wall of the auxiliary pressure strip 51 is set as a rounded structure. The sub-plate 3 is hinged to the upper surface of the flip strip 2 by a hinge piece 54. The hinge piece 54 hinges the sub-plate 3 to the flip strip 2. The rotating strip 2 enables the sub-plate 3 to rotate smoothly relative to the main plate 1 and to open and close repeatedly. The upper surface of the sub-plate 3 is provided with an auxiliary groove 53. The auxiliary groove 53 is located in the recessed space on the upper surface of the sub-plate 3 and is used to store the auxiliary pressure strip 51 and the edge of the chest pocket strip, so that the upper surface of the pressure strip is flush with the surface of the sub-plate 3. The left end of the inner wall of the auxiliary groove 53 is fixedly connected with an installation strip 52. The installation strip 52 is located at the left end of the auxiliary groove 53 and provides a groove interface to realize the detachable insertion and quick replacement of the auxiliary pressure strip 51.

[0021] Working principle: The whole machine is fixed horizontally to the sewing machine worktable with the main board 1 as a rigid reference. The fabric of the chest pocket strip to be sewn is placed in the double-layer clamping space formed between the main board 1 and the secondary board 3. At this time, the secondary board 3 is in a closed state and is kept horizontal by the hinge piece 54 and the flip strip 2, thereby forming a closed cover of the negative pressure adsorption channel, ensuring that the fabric adheres tightly to the upper surface of the main board 1 under the action of negative pressure without shifting.

[0022] According to the style requirements, the operator places the sewing template 41 with the corresponding hollowed-out pattern into the mounting groove 44 from top to bottom. The magnetic plate embedded in the back of the sewing template 41 and the magnetic strip 46 fixedly installed on the inner wall of the mounting groove 44 generate magnetic attraction, achieving tool-free initial fixation. At the same time, the mounting post 43 at the top corner of the rear surface of the sewing template 41 is inserted into the corresponding set of mounting grooves 45 at the top corner of the inner wall of the mounting groove 44, forming mechanical limit in the X and Y directions to prevent the template from rotating or shifting. The fixing strip 42 at the left end of the upper surface of the sewing template 41 further provides rigid pressure to counteract the lateral force caused by the high-speed vibration of the sewing machine, ensuring that the template has zero displacement throughout the entire sewing cycle.

[0023] The slide rail 48 is located on the right side of the mounting groove 44 along the sewing direction. The slider 481 can slide linearly within the slide rail 48. According to the process sheet requirements, the operator pushes the slider 481 to the target distance by observing the scale of the telescopic ruler 47 installed on the left surface of the slide rail 48. The telescopic ruler 47 indicates the displacement of the slider 481 in real time, realizing digital length setting. The positioning buckle 49 installed on the upper surface of the slider 481 moves to the sewing stop point. When the end of the chest pocket strip abuts the positioning buckle 49, the fabric length is uniquely determined, ensuring batch consistency. After the template and length are positioned, the sewing machine needle completes the front sewing of the chest pocket strip in one go along the hollow trajectory of the sewing template 41. The overall rigidity of the main board 1 ensures that the template does not vibrate when the needle punctures at high speed. The multi-point constraint system composed of the fixing strip 42, the mounting post 43, the mounting groove 45 and the magnetic strip 46 makes the sewing line completely coincide with the template trajectory.

[0024] After the front side is sewn, the operator releases the negative pressure, holds the secondary plate 3, and rotates it 180° upwards using the hinge 54 as the rotation center. The flipping strip 2 provides a flexible transition to prevent the fabric from being pulled. After the secondary plate 3 is flipped into place, the reverse side of the chest pocket strip faces upwards. At this time, the auxiliary component 5 enters the working state. The auxiliary groove 53 has a pre-installed installation strip 52. The operator inserts the trapezoidal outer contour and rounded corner auxiliary pressure strip 51 into the groove of the installation strip 52 to achieve quick assembly and disassembly. The trapezoidal structure of the auxiliary pressure strip 51 forms a gradually tightening pressure in the width direction, and the rounded corners prevent the fabric from being cut. At the same time, the pressure strip and the auxiliary pressure strip... The bottom of the auxiliary groove 53 is flush, ensuring that the stitching is flat and wrinkle-free when sewing the reverse side. After the reverse side is facing up, the sewing machine will complete the reverse side reinforcement or decorative stitching along the predetermined trajectory. The auxiliary pressure strip 51 and the sub-plate 3 work together to provide edge pressure, preventing the fabric from slipping due to the loss of negative pressure after turning over. After the reverse side sewing is completed, the finished chest pocket strip is taken out, the sub-plate 3 is flipped and reset, and all parts return to their initial state. The slider 481 can be quickly adjusted according to the size of the next batch under the guidance of the telescopic ruler 47. The sewing template 41 can also be replaced within a few seconds, achieving efficient continuous operation.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
