Description
Technical field
Sewing machine is the utility model is related to, more particularly to a kind of sewing machine for wire winding structure of setting up defences.
Background technology
The structure of sewing machine generally comprises sewing support, the sewing machine head being connected on sewing support and drive mechanism, seam
Head of threading is provided with sewing needle bar and selects bar, and sewing needle bar is fixed with sewing needle, and drive mechanism driving sewing needle moves up and down
While driving select bar up and down high speed swinging, select bar swing on driving sewing thread pump, realize sewing thread
Supply and recovery so that the stitching that upper thread and bottom line are formed is tightened up, and extract out from spool required for a stitching with line amount.
Under the drive that thread take-up tension lever drives the upper and lower high speed of sewing thread back and forth constantly to move, due to inertia, sewing thread can be taken up in parabolic
Line or round to sewing machine movement outside, somewhat it is careless be easy to be hooked by miscellaneous part twine and cause to break, be unfavorable for stitching
Machine of threading contact, smooth work.In order to overcome above-mentioned deficiency, initial solution is to set a thread take-up tension lever to protect in thread take-up tension lever
Cover, the outside of thread take-up tension lever is arranged at, and the ring of encirclement for forming a closing is connected with sewing machine housing, thread take-up tension lever is surrounded
In it；Then sewing thread passes from the string holes on thread take-up tension lever, is drawn from the both sides of protective cover；Although said structure is a certain degree of
Avoid to be hooked by miscellaneous part and twine and cause the phenomenon of broken string to occur；But from shield both sides draw sewing thread in thread take-up tension lever
At a high speed, pump process, still occurs that line movement locus is excessive and irregular, or easily occur by other portions
Part, which hooks, to be twined and causes the phenomenon of broken string to occur, be this further to have devised China Patent No. such as be 201520111996.3 disclosures
Wire winding structure of setting up defences sewing machine.Anti- wire winding structure in the patent document has the following disadvantages：Stop collar it is spacing go out
