Zipper feeding device of flat machine

Abstract

The invention relates to a zipper feeding device of a flat machine. The zipper feeding device comprises a flat machine plate (1) and is characterized in that a needle plate (2) is embedded into the flat machine plate (1), the needle plate (2) includes a fixed needle plate (2.1) and a drive needle plate (2.2) which are respectively arranged on the left and on the right, a presser foot (3) is arranged on the needle plate (2), a longitudinal guide groove (4) is arranged on the needle plate (2) on the left of the central line of the pressure foot (3), the guide groove (4) penetrates the needle plate (2), and the depth of the guide groove (4) 3-4mm. When the zipper feeding device is used, zipper teeth of a zipper are placed into the guide groove to allow the zipper to precisely move straightly along the guide groove, and the possibility of deviated feeding during sewing is avoided. The zipper feeding device can guarantee the high straight precision of zipper sewing and avoid substandard products.
