Lejiang/Nanbang-9820B

The Computer Direct-drive Eyelet Buttonholing Sewing Machine, model NB-9820B, is a cutting-edge solution designed for professional-grade buttonhole stitching. Built for precision and speed, this advanced Buttonhole Machine integrates intelligent engineering with refined mechanics to meet the rigorous demands of modern textile production.

Product Features

One of the standout features of the NB-9820B is its servo motor system, which ensures smooth, consistent operation with low vibration and noise. The direct-drive motor architecture eliminates belt slippage and enhances mechanical efficiency. It offers rapid start/stop response, providing a noticeable boost to production output and contributing to overall speed and efficiency on the production line.

The bobbin thread trimmer operates with remarkably low noise and minimal vibration, further supported by a unique thread clipper design that increases cutting reliability while reducing mechanical stress. In addition, the thread suction function ensures that no residual thread is left behind after stitching. This not only maintains the visual integrity of garments but also prevents rotary hook jams and core thread sliding—common issues that can impact traditional machines.

Another innovation lies in the lower oil cup and integrated tubing system, which is specifically designed to prevent oil spills. This system not only extends the life of the machine but also keeps the workplace cleaner and safer, making the NB-9820B an ideal option for environmentally conscious factories.

Applications

The NB-9820B is ideal for a wide range of clothing production needs, particularly for applications requiring high-speed and high-quality eyelet buttonholes. It is a core solution in suit jackets, shirts, uniforms, and industrial sewing machine environments where buttonholes are a central part of the garment design. Its capability to handle various fabric thicknesses makes it suitable for both lightweight and heavy-duty applications, including high-end fashion garments and workwear.

Thanks to its professional finishing, every buttonhole made by the NB-9820B is clean, consistent, and aesthetically refined. The machine’s robustness and high-precision threading system allow it to support production volumes in both small workshops and large-scale factories.

Common Questions

Q: Does the NB-9820B require frequent cleaning due to thread debris?
A: No. The machine includes a built-in thread suction mechanism that removes leftover thread, reducing the need for manual cleanup.

Q: How does the oil management system work?
A: It uses a lower oil cup with integrated tubing to minimize spills and control lubrication efficiently—ensuring both machine longevity and environmental safety.

Q: Is it suitable for thick fabrics?
A: Yes. The machine is engineered to maintain perfect stitching even through dense materials, making it highly versatile for different textile types.

Q: Can it be used continuously for long hours?
A: Absolutely. With its low-vibration motor and heat-efficient design, it’s made for extended industrial use with minimal downtime.
