Detailed description of the invention
As Figure 1-4, a kind of sewing-machine foot automatic shearing mechanism, comprise workbench 1, sewing machine head 2 and presser feet 3, it is characterized in that: described presser feet 3 comprises depression bar 31 and pressing plate 32, described pressing plate 32 has the trimming groove 33 parallel with flat station surface, thread trimmer 34 is installed in trimming groove 33, described thread trimmer 34 comprises cutter stator 35 and cutting blade 36, cutter stator 35 to be positioned at below cutting blade 36 and to be fixed on trimming groove 33, the position of the sewing stitch of the front portion correspondence of cutter stator 35 is provided with the edge of a knife 37, described depression bar 31 inside is provided with axis hole, have that rotating shaft 4 is accommodating is axis hole, the rear end of rotating shaft 4 lower end and cutting blade 36 is connected, the position of the corresponding rotating shaft 4 in rear portion of described cutter stator 35 has locating slot, the lower end of rotating shaft 4 is contained in locating slot, rotating shaft 36 top is connected with the output of drive unit 6 by a linkage, and drive unit 6 makes rotating shaft about 4 reciprocating rotation by linkage, and the front portion of described cutting blade 36 swings along with rotating shaft above the cutter stator edge of a knife 37.
Described drive unit 6 linear actuator, described linear actuator is fixed on bottom or the bottom of sewing machine head 1, described linkage comprises adapter sleeve 51 and movable rod 52, adapter sleeve 51 is tubular structure, the top of adapter sleeve 51 and the output shaft fixed connection of linear actuator, the sidepiece of adapter sleeve 51 middle and lower part offers axial loose slot 54, described movable rod 52 wherein one end is provided with bulb 53, described bulb 53 is contained in the kinematic pair forming one group of ball-and-socket and bulb in the adapter sleeve 51 of tubulose through axial loose slot 54, the position of the corresponding adapter sleeve 51 of described depression bar 31 sidepiece has through hole, the other end of movable rod 52 is connected through through hole and rotating shaft 4, described bulb 53 can move up and down in adapter sleeve 51 along with depression bar 31 and movable rod 52.
When the utility model uses, linear actuator is connected with the controller of Sewing machines, at the end of each sewing, controller can work by triggering linear actuator 6 automatically, linear actuator 6 promotes adapter sleeve 51 to a lateral movement, adapter sleeve 51 makes rotating shaft 4 produce rotation by movable rod, thus drive cutting blade 36 to rotate and cut off by the end of a thread, because thread trimmer 34 is close to workbench 1 surface, thread trimmer 34 shears rear web surface would not leave the end of a thread, also avoids occurring overlapping stitch simultaneously.
