The spinning movement of knife does not cause subject to obstruction.
Preferably, on the needle plate ontology integrally formed with the spacing block for separating pin hole and feeding gear slot,
Spacing block is subject to the movement for not hindering eedle in the thickness design of the setting of vertical shape up and down and spacing block, and spacing block extends down
Length to be subject to be more than tip position when eedle moves to minimum point.
Preferably, support reinforcing effect has been integrally machined on the needle plate ontology and in smooth plane or curved surface
Arc-shaped step, cambered surface is adapted cooperation on the outside of the cambered surface and moving knife of arc-shaped step, and the arc length of arc-shaped step, height design
It is subject to and does not stop moving knife spinning movement.
Preferably, the length of the arc-shaped step extends to the side of spacing block from needle plate ontology side.
Preferably, add in the side of the needle plate ontology medial surface and corresponding arc-shaped step integrally formed with boss is reinforced
The movement for not interfering feeding cam is subject in the shape setting of strong boss.
Preferably, the design of monoblock type is used between the pin hole and needle plate ontology.
Preferably, split-type design is used between the pin hole and needle plate ontology.
Preferably, above-mentioned split-type design, i.e. pin hole are provided on a seperated plate, offer counter sink on seperated plate,
Accordingly, the groove that the seperated plate of receiving is offered in the corresponding position of needle plate ontology, the counter sink of corresponding fission plate in groove
Position also offers threaded hole, and seperated plate is fixed in the groove of needle plate ontology by screw.
Compared with prior art, the beneficial effect that the present invention has is:
(1) by will be used on needle plate ontology for moving knife rotary motion pass through medial surface (i.e. needle plate bodies top medial surface) be
Smooth plane or curved surface, when the moving knife rotation of automatic sewing machine thread cutting mechanism is to cooperate trimming with stationary knife, moving knife rotation is suitable
Freely, it will not be hindered, trimming effect is good；
(2) because the distance between eedle and feeding gear require it is smaller, by needle plate bodies top medial surface and be located at needle
There is spacing block between hole and feeding gear slot, spacing block is in vertical shape setting up and down, to guarantee on eedle in sewing process
Suture can form stable wire loop and be caught on by rotating shuttle, to form continuous and stable stitching；
(3) arc that support reinforcing acts on is integrally machined on needle plate ontology and on being located on the outside of smooth plane or curved surface
Step can not only play moving knife guiding role, moreover it is possible to improve the intensity of needle plate ontology；
(4) arc-shaped step and reinforcement boss are separately positioned on to the two sides of front and back pin hole disposed in parallel, feeding gear slot, no
Cost is saved, it is ensured that the intensity of needle plate in only material saving.
