Description

Technical Field

[0001] This utility model relates to the field of leather sewing technology, specifically a sewing mold for automotive interior leather. Background Technology

[0002] Automotive interiors mainly refer to automotive products used for interior modifications of cars, covering all aspects of the car's interior, such as steering wheel covers, car seat cushions, car floor mats, car perfumes, car pendants, interior decorations, storage boxes, etc.

[0003] Utility model patent CN207958660U discloses a sewing device for automotive interior leather, including a feeding roller assembly, a base, an adjustment component, and a sewing machine base. The feeding roller assembly is respectively arranged on both sides of the upper end of the base, and the sewing machine base is installed at the middle position of the upper end of the base. An adjustment component is arranged between the feeding roller assembly and the sewing machine base.

[0004] This invention relates to a system where the position of the sewing needle at the lower end of the working rod changes as the sliding seat slides along the slide rail. A positioning sensor on the side of the working rod precisely positions the sewing area, ensuring the sewing needle sews the interior leather, thus avoiding inaccurate positioning and material waste. The system places the interior leather between the driving roller and the driven roller, and conveys it by compression. The conveying process can cause positional deviations in the interior leather, affecting sewing. The motor rotates, and the limiting plate rotates along the limiting groove, adjusting and limiting the position to ensure accurate conveying of the interior leather.

[0005] However, the movement of the leather is limited by the clamping and driving of the rollers at both ends. Since there are only two pieces of leather to be sewn, the leather is easily misaligned during clamping and conveying, resulting in unsatisfactory sewing quality. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] Please see Figure 1-3 This application discloses a sewing mold for automotive interior leather, comprising a worktable 1, with a sewing device 2 mounted on the upper side of the worktable 1 (the sewing device 2 being a prior art device); movable slots 11 are laterally formed on the upper side of the worktable 1 on the left and right sides of the sewing device 2, and conveyor belts 3 driven by an external drive device are respectively arranged in the two movable slots 11; the external drive device can be a conventional drive device. Clamping rollers 4 are respectively provided on the upper side of the worktable 1 corresponding to the upper side of the conveyor belts 3 on both sides of the sewing device 2, for clamping the leather placed on the conveyor belts 3. Fixing blocks 12 are respectively provided on the front and rear sides of the worktable 1 corresponding to the clamping rollers 4 for their rotation and insertion. In addition, a drive assembly 5 is provided on the worktable 1 for driving the sewing device 2 to move longitudinally on the upper side of the worktable 1.

[0025] Multiple support rollers 31 are evenly arranged inside the two conveyor belts 3 to enhance the stability and durability of the conveyor belts 3. The number of clamping rollers 4 located on the upper side of the conveyor belts 3 on both sides of the sewing equipment 2 matches the number of support rollers 31 and corresponds one-to-one with the support rollers 31 to ensure smooth transmission of leather during the sewing process.

[0026] Furthermore, the drive assembly 5 includes a threaded rod 51 horizontally and longitudinally disposed within the worktable 1. One end of the threaded rod 51 is rotatably disposed on the inner wall of the movable through groove 13, and the movable through groove 13 is formed on the surface of the worktable 1 corresponding to the threaded rod 51, penetrating the upper and lower surfaces of the worktable 1. The bottom of the sewing device 2 is longitudinally slidably disposed within the movable through groove 13, and the other end of the threaded rod 51 passes through the portion of the sewing device 2 located within the movable through groove 13 and is threadedly connected thereto. This design allows the sewing device 2 to move longitudinally along its side on the worktable 1, thereby adapting to sewing needs at different angles.

[0027] To achieve automated control, a motor 52 is provided on the side wall of the workbench 1 at the end corresponding to the threaded rod 51 rotatably connected to the movable through slot 13, which can drive its rotation. The motor 52 is connected to an external drive device through a control system, and can automatically adjust the speed and direction of the conveyor belt 3 according to the sewing speed.

[0028] The sewing device 2 is provided with a sliding block 21 at the corresponding movable through groove 13, which slides back and forth along the movable through groove 13. The other end of the threaded rod 51 passes through the sliding block 21 and is threadedly connected to it. When the sewing device 2 slides back and forth in the movable through groove 13, the sliding block 21 can ensure that the sewing height is always adapted to the upper side of the worktable 1, thereby ensuring the quality of sewing.

[0029] Meanwhile, in order to limit the movement range of the sewing device 2 and prevent it from deviating from the predetermined path during operation, the sewing device 2 is provided with limiting sliders 22 on both the left and right sides of the movable channel 13. Correspondingly, limiting grooves 14 are respectively provided on the left and right sides of the movable channel 13 at the positions corresponding to the limiting sliders 22, allowing them to slide horizontally and longitudinally.

[0030] Furthermore, positioning plates 6 are symmetrically arranged on the front and rear sides of the upper side of the clamping roller 4 on the left side of the sewing equipment 2, and a clearance groove 61 is opened on the lower side of the positioning plate 6 corresponding to the clamping roller 4. A guide rod 62 is arranged horizontally and longitudinally on the worktable 1 to allow the positioning plate 6 to move longitudinally on the upper side of the worktable 1. The two ends of the guide rod 62 are fixed to the corresponding fixing blocks 12 on the upper side of the worktable 1. This design can adjust the position of the clamping roller 4 according to different sizes of leather to ensure sewing accuracy.

[0031] Furthermore, to ensure that the upper side of the conveyor belt 3 and the upper side of the worktable 1 are on the same horizontal plane, the height of the support roller 31 can be adjusted. This ensures that the leather will not wrinkle or shift due to height differences during transmission, thus improving sewing quality.

[0032] In conclusion, this automotive interior leather sewing mold, through its rational structural design and precise mechanical coordination, enables efficient and accurate sewing of leather of different sizes and shapes. Its unique design not only improves production efficiency but also ensures product quality, demonstrating high practical value and promising application prospects.
