Description

Technical Field

[0001] The utility model relates to the technical field of sewing equipment, in particular to a positioning and cutting component of a full-automatic placket sewing machine. Background Art

[0002] At present, there are generally two ways to process a placket on a fabric product. One is to sew it manually using an ordinary flat-bed sewing machine, and the other is to sew it automatically using a fully automatic placket sewing machine.

[0003] When using an ordinary flat-bed sewing machine for manual sewing, first sew a few seams on the fabric, then remove the fabric and cut the parts between the seams with scissors or a blade. It is difficult to control the length, straightness and inclination of the seams when sewing manually, and it is easy to damage the fabric when cutting it manually, so the speed of manual sewing of the placket is slow and the process quality is unstable. When using a double-needle placket sewing machine for automatic sewing, two seams can be sewn at the same time, and the overall efficiency is improved. Fully automatic placket sewing machines are increasingly used in the sewing field.

[0004] During the sewing process of the existing fully automatic placket sewing machine, since a placket needs to be processed, the fabric product is prone to displacement or misalignment during the sewing process, affecting the placket yield rate. Moreover, the placket sewing machine only cuts the seam line segment from the top, and it is easy for the seam line to not be completely cut off in one cut, affecting subsequent sewing operations.
