Description

Technical Field

[0001] The utility model relates to the technical field of textiles, in particular to a clothing sewing machine with a thread breaking function. Background Art

[0002] The development of clothing sewing machines can be traced back to the Industrial Revolution in the mid-18th century. With the rise of the textile industry, people began to explore mechanized sewing technology. Early sewing machines were mostly hand-cranked, such as the single-thread chain stitch hand-cranked sewing machine invented by British carpenter Thomas Sander in 1790. In 1851, American machinist IM Singer invented the lock stitch sewing machine, marking a major breakthrough in sewing machine technology. In the 20th century, sewing machines gradually realized electrification and intelligence, becoming an indispensable equipment in the modern clothing industry.

[0003] In the processing of clothing, sewing machine is one of the commonly used machines. After the stitches are sewn, the user needs to take scissors to cut the stitches before sewing the next piece of clothing.

[0004] However, most of the devices on the market currently cut directly with scissors, which wastes time and reduces efficiency. In view of this, we propose a clothing sewing machine with a thread cutting function. Utility Model Content
