Description

Technical Field

[0001] This utility model relates to a sewing machine for stitching webbing into a loop shape, and more particularly to a dual-function elastic band sewing machine. Background Technology

[0002] The same applicant filed a patent application on April 7, 2022, with publication number CN217104283U, for a fully automatic elastic band sewing device. The device processes a long elastic band strip through an ultrasonic vibrating head and a cutting and welding knife to form an elastic band ring with low welding strength at the joint. The ring is then clamped by an inner sliding clamp and an outer sliding clamp and sent to a sewing machine for sewing. The applicant found that this product is only suitable for webbing containing hot melt wires and has a limited scope of application. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a dual-function rubber band splicing machine.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A dual-function elastic band splicing machine includes a frame on which at least one sewing machine, a feeding mechanism for conveying webbing, and a conveying mechanism for conveying looped webbing to the sewing machine for processing are mounted. A waste conveying mechanism corresponding to the feeding mechanism is mounted on the frame. A telescopic bar controlled by a first drive mechanism is mounted on the lower side between the feeding mechanism and the waste conveying mechanism. A flipping mechanism controlled by a second drive mechanism is mounted on the frame corresponding to the position of the telescopic bar. Only one of the telescopic bar and the flipping mechanism can be used at a time, and the second drive mechanism controls the flipping mechanism to move and avoid obstructing the extension of the telescopic bar.

[0006] An ultrasonic cutter mold controlled by a third drive mechanism is installed on the side of the waste conveying mechanism near the feeding mechanism, and a cutter controlled by a fourth drive mechanism is installed in the feeding mechanism corresponding to the ultrasonic cutter mold.

[0007] An alignment mechanism controlled by a fifth drive mechanism is installed below the ultrasonic cutter mold within the waste conveying mechanism. The alignment mechanism consists of a static plate and a dynamic plate, with the inner side of the static plate aligned with one side of the webbing on the feeding mechanism.

[0008] The frame is equipped with a first slide rail, and a first slider is mounted on the first slide rail. The flipping mechanism is fixed on the first slider.

[0009] The beneficial effects of this utility model are as follows: This utility model has at least one sewing machine, a feeding mechanism for conveying webbing, and a conveying mechanism for conveying the looped webbing to the sewing machine for processing installed on the frame. A waste conveying mechanism corresponding to the feeding mechanism is installed on the frame. A telescopic bar controlled by a first drive mechanism is installed on the lower side between the feeding mechanism and the waste conveying mechanism. A flipping mechanism controlled by a second drive mechanism is installed on the frame corresponding to the position of the telescopic bar. Only one of the telescopic bar and the flipping mechanism can be used at the same time, and the second drive mechanism controls the movement of the flipping mechanism to avoid the extension of the telescopic bar. By using either the telescopic bar or the flipping mechanism, the looping effect of hot melt wire or products without hot melt wire can be achieved, and the application range is wide.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0018] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.

[0019] The following describes some embodiments of the present invention with reference to the accompanying drawings.

[0020] Reference Figure 1-6A dual-function elastic band splicing machine includes a frame 1, on which at least one sewing machine 2, a feeding mechanism 3 for conveying webbing, and a conveying mechanism 4 for conveying looped webbing to the sewing machine 2 for processing are mounted. A waste conveying mechanism 5 corresponding to the feeding mechanism 3 is mounted on the frame 1. A telescopic rod 6 controlled by a first drive mechanism 10 is mounted on the lower side between the feeding mechanism 3 and the waste conveying mechanism 5. A flipping mechanism 7 controlled by a second drive mechanism 11 is mounted on the frame 1 at the position corresponding to the telescopic rod 6. Only one of the telescopic rod 6 and the flipping mechanism 7 can be used simultaneously, and the second drive mechanism 11 controls the flipping mechanism 7 to move and avoid the extension of the telescopic rod 6. By using either the telescopic rod or the flipping mechanism, looping effects of hot melt wire or products without hot melt wire can be achieved, making it widely applicable.

[0021] An ultrasonic cutter mold 8 controlled by a third drive mechanism 13 is installed in the waste conveying mechanism 5 on the side near the feeding mechanism 3, and a cutter 9 controlled by a fourth drive mechanism 14 is installed in the feeding mechanism 3 corresponding to the ultrasonic cutter mold 8.

[0022] An alignment mechanism 16, controlled by a fifth drive mechanism 15, is installed below the ultrasonic cutter mold 8 within the waste conveying mechanism 5. The alignment mechanism 16 consists of a static piece 17 and a dynamic piece 18. The inner side of the static piece 17 is aligned with one side of the webbing on the feeding mechanism 3. When the front end of the webbing is conveyed to the alignment mechanism 16, the dynamic piece 18 moves closer to the static piece 17 until the width of the static piece 17 and the dynamic piece 18 is the same as the width of the webbing, so that the two sides of the end of the webbing are aligned with the two sides of the webbing body (the webbing body is the production raw material, and it is only necessary to align the webbing on the feeding mechanism 3), thus avoiding misalignment of the beginning and end of the webbing when forming loops.

[0023] When looping webbing without hot melt yarn, the flipping mechanism 7 is used. During production, the webbing leaves from the front end of the feeding mechanism 3 and hangs down to the flipping mechanism 7. The clamp of the flipping mechanism 7 clamps the front end of the webbing and flips it 180° to loop it. After the webbing is looped, the feeding mechanism continues to feed the webbing to the preset length. At this time, it is cut by the cutter 9 and then the looped webbing is conveyed by the conveying mechanism 4 to the sewing machine 2 for processing. This method is suitable for sewing structures where the two ends of the webbing are aligned, resulting in a flatter appearance. It is also suitable for sewing structures where the two ends of the webbing are overlapped, resulting in higher sewing strength. Since the webbing does not contain hot melt yarn, the end of the webbing is completely cut off after the cutter 9 cuts it.

[0024] The flipping mechanism 7 can be a high-efficiency looping mechanism for webbing, as disclosed in CN222455621U, and the conveying mechanism 4 can be a feeding mechanism for webbing looping and sewing, as disclosed in CN222455466U.

[0025] When forming loops of webbing containing hot melt wire, the second drive mechanism 11 controls the movement of the flipping mechanism 7 to avoid the extension of the telescopic rod 6. Then, the first drive mechanism 10 controls the extension of the telescopic rod 6, thus switching between the telescopic rod 6 and the flipping mechanism 7. Initially, the webbing is pulled to the waste conveying mechanism 5 (the waste conveying mechanism 5 is equipped with a motor structure for pulling the webbing, which is conventional technology and will not be described in detail). The webbing is conveyed by the feeding mechanism 3, and the webbing is recessed between the feeding mechanism 3 and the waste conveying mechanism 5 until the lower end of the webbing is below the telescopic rod 6. The telescopic rod 6 extends and passes through the recessed area of ​​the webbing. At this time, the feeding mechanism 3 continues to convey the webbing forward to a preset length (during this period, the telescopic rod 6 separates the two sides of the webbing to prevent static electricity from causing the two sides of the webbing to attract each other, preventing normal operation). When the webbing loops, it is cut by the cutter 9. Since the webbing contains heat-fused fibers, the webbing below the cutter 9 loops during cutting, and the cut ends are initially bonded. It is then conveyed by the conveying mechanism 4 to the sewing machine 2 for sewing. This structure is only suitable for sewing structures where the two ends of the webbing are aligned. The webbing above the cutter 9 is also bonded (i.e., the webbing on the feeding mechanism 3 and the webbing on the waste conveying mechanism 5 are bonded). At this time, the waste conveying mechanism 5 conveys the webbing above the cutter 9 a short distance, moving the bonded position towards the waste conveying mechanism 5. This prevents the bonded position from being on the looped webbing when the next looped webbing is formed, ensuring that each looped webbing has only one joining position. The webbing conveyed to the waste conveying mechanism 5 is production waste, which will be uniformly processed later (not the focus of this application and will not be elaborated).

[0026] A first slide rail is installed on the frame 1, and a first slider 19 is installed on the first slide rail. The flipping mechanism 7 is fixed on the first slider 19. Furthermore, the length direction of the first slide rail is consistent with the conveying direction of the webbing. The first slide rail and the second drive mechanism 11 are installed at the bottom of the waste conveying mechanism 5, and the bottom of the waste conveying mechanism 5 has sufficient space for installation.

[0027] The frame 1 is equipped with a vertically upward second slide rail 20, and a second slider 22 controlled by a sixth drive mechanism 21 is slidably mounted on the second slide rail 20. The first drive mechanism 10 is fixed to the second slider 22, so that the telescopic rod 6 has the function of vertical adjustment. The frame 1 is provided with a vertical waist-shaped hole 24. A guide part 23 is installed on the second slider 22. The telescopic rod 6 is guided by the guide part 23 to improve the telescopic effect of the telescopic rod 6.
