Technical Field

[0001] The invention relates to the technical field of sewing machines, and in particular to a thread routing device of a sewing machine. Background Art

[0002] A sewing machine is a machine used to sew various materials. It uses a needle and thread to form stitches on the fabric, interweaving or sewing one or more layers of material. The sewing machine completes the sewing operation through mechanical movement. When working, the thread is placed in the thread cup and passed through the thread guide device. After starting, the mechanical parts start to move, and the thread guide device moves the thread down to pull the fabric. The needle pierces and passes through the fabric, while pulling the thread from the thread cup to form a loop of stitches. This process is repeated until the sewing operation is completed. Types of sewing machines, sewing machines can be divided into many types according to their uses and functions. Household sewing machines are usually small in size and easy to operate, suitable for daily household sewing needs. They may have multiple functions such as automatic threading, hemming, buttoning, and buttonholes. Industrial sewing machines have higher sewing speeds and stronger durability, suitable for large-scale production needs. They may be equipped with more advanced control systems and automation functions to improve production efficiency and product quality.
