Document Type and Number:
WIPO Patent Application WO/2021/135199
Kind Code:
A1
Abstract:
A sewing machine feeding mechanism (100). A main shaft driving member (21) can drive a feed dog (11) to do reciprocating translational motion relative to a needle plate (10); a feed dog driving member (40) is connected to a feed dog rack (12), and the feed dog driving member (40) can drive the feed dog (11) to do reciprocating raising motion relative to the needle plate (10); the main shaft driving member (21) and the feed dog driving member (40) are both connected to a controller; and the controller can control operation of the main shaft driving member (21) and the feed dog driving member (40). The two driving members of the sewing machine feeding mechanism (100) respectively control translational and lifting motion of the feed dog (11), changes of the transmission speeds of the main shaft driving member (21) and the feed dog driving member (40) can make the feed dog (11) form multiple cloth feeding forms, so that sewing material styles are diversified, and the controller can coordinate motion of the main shaft driving member (21) and the feed dog driving member (40) to ensure normal sewing. Provided is a sewing machine comprising the sewing machine feeding mechanism (100). The sewing material styles of the sewing machine are diversified, and the sewing machine has broad application prospects.
