Description
Technical field
The present invention relates to a kind of height adjustment mechanism of cloth-feeding teeth of sewing machine and its application methods, belong to sewing machine manufacture skill
Art field.
Background technique
Currently, sewing industry flat seam machine realizes that cloth in the movement of needle plate upper surface, is sent by the movement of feed dog frame
The tooth of cloth retainer exposes from the upper surface of needle plate and withstands on the lower surface of cloth, and feed dog frame moves and pushes cloth along needle
Plate upper surface is mobile, exposes needle plate upper level according to tooth and is adapted to different sewing operating conditions；When user sews difference
When thickness and the fabric of material, it is often necessary to adjust angle (i.e. the adjustment feeding timing and tooth height of retainer seat and feed lifting fork
Degree).Flat seam machine is broadly divided into thin material and thick material type, and one of thickness material and thin material type main difference point are exactly the tooth of feed dog frame
Tooth exposes needle plate height difference, and the feed dog frame tooth of thickness material type is higher by needle plate face height and is higher than thin material type, for thickness
Expect type, compression of the feed dog frame on cloth doubles, and can provide stronger work feed ability.
When feed dog frame in the prior art needs to adjust height, for different sewing fabrics is switched, user needs to adjust
Multiple mechanical structure parts are saved, adjustment process is often more complicated, time-consuming more long.
