Description
Technical field
The present invention relates to sewing machine, the material feeding driving mechanism and sewing machine of more particularly to a kind of sewing machine.
Background technology
Traditional sewing machine, the main motor (servomotor) of sewing machine is connected with main shaft, main motor drive main axis from
And drive the eccentric wheel for being fixed on main shaft to rotate；Eccentric wheel is rotated and drives work feed connecting rod and lift tooth link motion；Work feed connecting rod
Cloth pushing shaft is driven to rotate through swinging holder assembly, lift tooth connecting rod drives feed lifting rock shaft to swing through feed lifting rock shaft crank；The wobble drive of cloth pushing shaft
The retainer being fixed on cloth pushing shaft is swung so as to provide the motion in level of approximation direction for feed dog；Feed lifting rock shaft swings to drive and is connected
Swung so as to provide the motion of approximate above-below direction for feed dog in the feed lifting fork on feed lifting rock shaft.Thus, it is known that feed dog is most
Final orbit mark is synthesized with the motion of vertical above-below direction by the motion of horizontal fore-and-aft direction and forms.Closed because lift tooth is synchronous with work feed
System determines that therefore it cannot be adjusted by eccentric size of wheel.Therefore same sewing machine only has a kind of work feed track, it is impossible to arbitrarily adjust
