AI Technical Summary
The feeding mechanism of a sewing machine is prone to deviation during the process of moving the fabric, which leads to a decrease in sewing quality.
The design employs a combination of guide components and transmission components. The guide components adjust the gap according to the fabric width to ensure close contact with the fabric, while the transmission components push the fabric through circular motion. Combined with a limiting plate and a lubricating coating, the fabric movement is stabilized.
It effectively prevents the fabric from shifting during movement, improves the stability and convenience of the fabric, reduces friction, and avoids needle hole misalignment during the sewing process.
