Abstract

The utility model relates to a needlework supplying device used for sewing machine. a power set is disposed on the needlework supplying device to push the thread crossing shaft and drive the dialing plate to move; when the dialing plate is lifted into and open a needle/thread clamping set, the thread between the fulcrum and the wire hanging plate is shortest and smoothest; when the dialing plate is drawn out from the needle/thread clamping set, the needle/thread set clamps the sewing thread tightly; the power set continues to push the thread crossing shaft to tension the sewing thread; the length of the thread between the fulcrum and the wire hanging plate is prolongs, and because the needle/thread set clamps the sewing thread tightly, the sewing thread can not obtain the thread between the fulcrum and the thread hanging plate from the needle/thread supplying device, only can recover thread from the front of the sewing thread head; therefore, the purposes of shortening sewing thread and omitting artificial stub cutting work are achieved.

Description

The needlework supply device of Sewing machines
Technical field
The utility model relates to a kind of needlework supply device of Sewing machines, especially finger is a kind of can be by the design of needlework folder group, passing spool group, group plate and power packages, see through power packages push-and-pull passing spool group, make the passing spool group drive group plate and strut or withdraw from needlework folder group, make and have the line of adjusting amount, reduce the unnecessary effect that plays suture head length degree, and be applicable to various Sewing machines type or similar structures person.
Background technology
Press, existing automatic tangent Sewing machines finishes at sewing, when the action of automatic tangent is finished, can keep one section needlework (the end of a thread is apart from the about 40mm of the length of pin hole) on the car pin, and the end of a thread slips out pin hole when stitching to avoid rise next time, causes again the trouble of threading.But this section needlework play when seam in next time and can be introduced by the car pin below the cloth by rotating shuttle toward drop-down again, and form an excessive thread ends below first pin of cloth, and are easy to cause outward appearance not good, or need manually repair except that excessive thread ends length again.
So, there is Sewing machines manufacturing dealer to develop the mode that has reduced suture head length degree, as disclosed Chinese invention patent publication number is CN101372797A " Sewing machines and the method that starts with this stitching sewing machine linear slit ", it ties up to the electromagnet of additional 3 groups of control sequential on the existing automatic tangent Sewing machines, but because its mechanism is comparatively complicated, cost is too high, so still do not meet the required of user on reality is used.
