Description

Technical Field

[0001] The utility model relates to the technical field of clothing processing, in particular to an auxiliary thread routing mechanism of a sewing machine. Background Art

[0002] Within the clothing manufacturing industry, shirt production processes are particularly sophisticated and complex, particularly the design and production of sleeves, which are directly related to wearing comfort and overall aesthetics. To enhance the wearing experience, many shirt sleeves feature slits, which not only facilitate free arm movement but also visually add a sense of layering and fashion. Key technical aspects of the slit production process include distinguishing between the large and small sides and their subsequent processing. The "sealing three-point" step is particularly crucial, requiring the large side fabric to be specifically folded to form a three-pointed shape, which is then precisely sewn to the other side of the slit. This process not only tests the worker's manual skills but also directly determines the quality and appearance of the finished shirt sleeve.

[0003] However, traditional three-point seam sealing is almost entirely manual. Workers rely on extensive experience and superb skills to fold the fabric into a precise three-point shape and maintain high concentration and patience during the sewing process to ensure the straightness and beauty of the seam. However, this highly manual operation has many limitations: manual operation is extremely labor-intensive. Long periods of manual folding and sewing not only easily lead to worker hand fatigue, but also may cause occupational diseases such as wrist and cervical spine problems, posing a potential threat to workers' physical health. Manual operation is also limited in speed, making it difficult to meet the demand for efficient production in the modern garment manufacturing industry. Therefore, we have made improvements to this problem and proposed a sewing machine auxiliary thread routing mechanism. Summary of the Invention
