Description

Technical Field

[0001] This utility model relates to the field of sewing technology, specifically to a sewing device for a windbreaker. Background Technology

[0002] The outdoor jacket sewing machine is a professional sewing device designed specifically for high-performance outdoor clothing. Its core features include a reinforced needle bar system and a high-torque motor to handle the sewing needs of multi-layered composite fabrics. The machine is typically equipped with a special presser foot and a microcomputer-controlled thread tension system to ensure even and fine stitches when sewing high-density nylon fabric and waterproof tape. It also features a hot air device or ultrasonic finishing function to prevent fabric fraying at the cut edges.

[0003] Currently, existing outdoor jacket sewing devices typically involve sewing the outdoor jacket fabric together. However, during use, the fabric is manually pushed, which can be dangerous due to operator inattention. Furthermore, when sewing stiff outdoor jacket fabrics, the thread is prone to breakage, requiring multiple threading attempts. Existing needles cannot easily thread the thread, creating a problem with threading efficiency. Utility Model Content

[0025] Specifically, the sewing machine body 1, the sewing needle 13, and the worktable 2 constitute the existing sewing device.

[0026] Please refer to Figure 1. Figure 5 The transmission belt 3 of the transmission structure is located on both sides of the sewing needle 13. The transmission belt 3 is equipped with a transmission roller 17. One end of the transmission roller 17 is fixedly connected to the output shaft of the servo motor 18. The outer bearing of the transmission roller 17 is connected to the worktable 2.

[0027] Specifically, the servo motor 18 is a dual-axis motor, with its two ends connected to the transmission roller 17 respectively.

[0028] Please refer to Figure 1. Figure 4 A limiting block 6 is fixedly connected to one side of the sewing machine body 1. The outer side of the limiting block 6 slides in the movable groove of the connecting plate 5. A supporting spring is provided on the upper part of the limiting block 6.

[0029] Specifically, the limiting block 6 fits closely with the movable slot of the connecting plate 5, and the moving distance of the limiting block 6 within the movable slot is the moving distance of the supporting wheel 10.

[0030] Please refer to FIGS. 1 to Figure 2 , a stop block 9 is slidably connected inside a convex block on one side of the sewing machine main body 1, and a fixing slot 8 is formed on one side of the movable frame 7, and the fixing slot 8 is connected to the stop block 9.

[0031] Specifically, the stop block 9 is in the shape of a工字 (I-shaped), the convex block on one side of the sewing machine main body 1 is provided with a movable slot, the lower part of the stop block 9 slides within the movable slot, and the shape of the movable slot is convex-shaped.

[0032] Please refer to Figure 1 , Figure 5 , the supporting wheels 10 correspond to the position of the conveyor belt 3, a plurality of support wheels 10 arranged in a linear array are provided at the lower part of the connecting block 4, and a heat dissipation port is provided at the lower part of the workbench 2 under the servo motor 18.

[0034] Please refer to Figures 2 to 4 , the thread hook 12 can be inserted into the needle hole of the sewing needle 13, and a support spring 16 is provided at the upper and lower parts of the support rod 15 respectively, and both ends of the support spring 16 are fixedly connected to the baffle 11 and the connecting frame 14 respectively.

[0035] Specifically, the thread hook 12 is located at the lower part of the sewing machine main body 1, and a hook groove for winding the sewing thread is provided at the end of the thread hook 12.

[0036] Note: In the translation of "工字 (I-shaped)", since "工字" is a Chinese character representing the shape, it is directly transliterated here. If there is a more accurate English equivalent for this shape in the context of sewing machine parts, it can be replaced accordingly.In use, the waterproof jacket fabric is placed on the workbench 2. The connecting block 4 is moved downwards, causing the support wheel 10 to press down on the upper part of the waterproof jacket fabric. The servo motor 18 is activated, driving the transmission roller 17 to rotate, causing the conveyor belt 3 to move the waterproof jacket fabric. In conjunction with the support wheel 10, the fabric is conveyed. Through the arrangement of the conveyor belt 3, servo motor 18, transmission roller 17, connecting block 4, and support wheel 10, the waterproof jacket fabric can be automatically transported. When the connecting block 4 moves downwards, the limiting block 6 controls the lifting range of the connecting block 4. After the movable frame 7 moves downwards, the stop block 9, through the support set at the bottom... The supporting spring moves inward, thereby sliding the stop block 9 into the fixed groove 8, thus fixing the movable frame 7 and fixing the support wheel 10 in place. After use, the stop block 9 is pulled outward, and the supporting spring on the upper part of the limiting block 6 pushes the movable frame 7 upward, thereby separating the support wheel 10 from the fabric. Through the cooperation of the movable frame 7, limiting block 6, connecting plate 5, stop block 9 and fixed groove 8, the support wheel 10 can be fixed during use, thus playing a role in conveying the waterproof jacket fabric in conjunction with the conveying structure, achieving the purpose of reducing danger when the sewing device conveys the waterproof jacket fabric.

[0037] When the sewing machine body 1 is started, and the sewing needle 13 is used to sew the waterproof jacket fabric, the fabric is relatively stiff and the sewing thread is prone to breakage, requiring re-threading. To re-thread, the support rod 15 is pushed, causing the thread hook 12 at one end to insert into the corresponding needle eye of the sewing needle 13. The sewing thread is then placed into the thread hook 12, which pulls the thread through the needle eye of the sewing needle 13. Through the arrangement of the thread hook 12, sewing needle 13, support rod 15, and connecting frame 14, the sewing process is complete. The needle 13 facilitates threading. After the sewing thread is wrapped around the hook 12, the support rod 15 is released, and the support spring 16 pulls the support rod 15 back to its original position, thus separating the hook 12 from the sewing needle 13. The sewing thread is then threaded into the needle eye. Through the cooperation of the baffle 11 and the support spring 16, the hook 12 can automatically reset during use, thus facilitating the threading of the sewing thread into the needle eye of the sewing needle 13 and achieving the purpose of convenient threading.
