At present, by introducing automation control systems and artificial intelligence technology, industrial sewing machines can achieve a higher degree of automation and intelligent production, reduce manual intervention, and improve production efficiency and product quality. Digital technology enables sewing machines to precisely control sewing parameters, ensuring product consistency and stability; Network technology enables remote monitoring and maintenance, improving the convenience and flexibility of production management. Modern industrial sewing machines pay more attention to energy conservation and environmental protection in their design, using low-energy motors, optimizing mechanical structures, and other methods to reduce energy consumption and noise pollution, while reducing negative impacts on the environment.

The working principle of a sewing machine mainly includes four steps: thread transfer, pinhole formation, stitch formation, and fabric transfer. The sewing machine provides two threads, upper and lower, through a spool, which enter the machine body through a guide, tensioner, and spool to ensure smooth thread transfer. The sewing machine forms needle holes through the reciprocating motion of the upper and lower needles. When the needle moves downwards, the upper needle passes the thread through the fabric through the thread plate and the lower needle eye plate, forming a needle eye. The formation of a trace depends on the interweaving of online and offline lines. When the upper needle passes down through the fabric, it will thread the upper thread through the fabric and interweave with the lower thread in the needle eye, forming a stitch. The sewing machine transfers fabric through the lower hem, upper hem, and gear transmission. When the gear rotates, the lower swing and upper swing move alternately, conveying the fabric forward.
