Technical Field
[0001] The utility model relates to the technical field of embroidery machines, and particularly relates to a segmented independent presser foot mechanism based on hole embroidery. Background Art
[0002] Hole embroidery, also known as punched embroidery, is a kind of embroidery method that uses tools such as hole-cutting knives or hole-cutting needles installed on an embroidery machine to punch holes in the embroidery fabric and then perform edge embroidery. This is a kind of embroidery method that has certain difficulties in plate making and equipment, but the effect is very distinctive. The hole embroidery can be embroidered by a large machine and a flat embroidery machine. Now, a laser machine has also been newly developed, but the technology is not very mature and the efficiency is very low, so its popularity is limited. There are very few users of the original machine. Most people use large machines and flat embroidery machines for hole embroidery, and most flat embroidery machines are used for cut piece embroidery.
[0003] During the working process of a hole embroidery machine, the fabric is placed on the needle plate. The cutter head moves up and down above the needle plate to punch holes in the fabric. During this process, the fabric is very easy to be rolled into the needle holes of the needle plate. The presser foot is a component used to apply pressure on the surface of the sewing material on a sewing machine. It is an essential part of the feeding mechanism of the sewing machine. The main function of the presser foot is to fix the fabric, keep it flat during sewing, and ensure the correct position and uniform tension of the sewing thread. Summary of the Invention
