Abstract
The invention relates to a needle thread supplying device applied to a sewing machine; a power group for pushing a thread passing shaft group and driving a lifting plate to act is arranged on the needle thread supplying device; when the lifting plate enters for unfolding a needle thread clamp group, the thread amount between a support point and a thread hanging plate is the shortest and is also the smoothest; when the lifting plate exits the needle thread clamp group, the needle thread clamp group closely clamps suturing threads, the power group continuously pushes the thread passing shaft group for tensioning the suturing threads; the thread amount between the support point and the thread hanging plate is lengthened; and as the needle thread clamp group closely clamps the suturing threads, the suturing threads cannot obtain the thread amount between the support point and the thread hanging plate from the needle thread supplying device, and can only recycle the thread amount from the front end of the head of the suturing head; therefore, the length of a suturing needle thread is shortened, and the work on manually removing the length of extra thread heads is omitted.
Description
Technical field
The present invention 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.
Summary of the invention
Main purpose of the present invention ties up to provides a kind of needlework of Sewing machines supply device, Combination Design by a pedestal, at least one needlework folder group, a passing spool group, one group of plate, at least one fulcrum, a line link plate and a power packages, utilizing power packages push-and-pull passing spool group drive group plate to head into struts or withdraws from the needlework folder group, when needlework folder group is headed into when strutting, line amount between its fulcrum and the line link plate is the shortest, also is the most smooth and easy; When group plate withdraws from needlework folder group, needlework folder group clamps suture, power packages continues to promote the passing spool group with tensioning suture, line quantitative change between this fulcrum and the line link plate is long, and because of needlework folder group clamping suture, suture can not can only can be reached and shorten suture needle line length and cost-effective purpose from suture head front end exhausting line amount from the line amount between needlework supply acquisition fulcrum and the line link plate.Make have easy to use, reduce excessive thread ends and save effects such as cost, increase whole practicality and convenience.
Secondary objective of the present invention ties up to provides a kind of needlework of Sewing machines supply device, is combined into one by suture pressure adjustment group and structure of the present invention, makes it have the best and makes flowing mode, and then increase its practicality.
