Detailed description of the invention:
With specific embodiment, the invention will be further described below, sees Fig. 18:
The thread cutting method of a kind of sewing machine, comprises the steps:
1), when being made without trimming, motion knife rest 1 and lower axle 3 are in released state, and lower axle 3 rotates, and motion knife rest 1 is not
Rotating, be provided with cutter one on motion knife rest 1, the present embodiment selects moving knife 2.
2) when controller receives trimming signal, before rotating shuttle 4 forwards trimming angle to, controller controls power part and drives
Clutch makes motion knife rest 1 be connected with lower axle 3 and rotate therewith, and now, moving knife 2 rotates the most together.
3) point of a knife 5 of moving knife 2 is through the wire loop of upper thread 6, the bracing wire groove 7 on moving knife 2 with upper thread 6 and bottom line 8 to
Cutter two moves, cutter two can be stationary knife can also be moving knife, the present embodiment select stationary knife 9, when the sword of the moving knife 2 with upper thread 6
When mouth 10 is engaged with the cutting edge of stationary knife 9, line is cut off, completes trimming action.
4) after being cut off by line, lower axle 3 is rotated further with motion knife rest 1, until sewing machine is stopping the stopping of pin position, motion cutter
Frame 1 separates with lower axle under the effect of clutch, and motion knife rest 1 stops operating, and waits trimming operation next time.
The present invention, departing from the trimming cam in existing structure, the action utilizing lower axle 3 main motion to rotate a circle, completes one
Secondary trimming process, from initial position, rotates a circle, is eventually returned to initial position, completes a trimming.Motion can be realized
