Abstract
The invention relates to a stable thread tensioning device of a sewing machine. The stable thread tensioning device comprises a center shaft and two annular compacting sheets, namely a first compacting sheet and a second compacting sheet, which are sleeved on the shaft; the two compacting sheets are arranged oppositely; and a compacting device is arranged at the outer side of the first compacting sheet. The stable thread tensioning device is characterized in that an antiskid layer is arranged at the inner side of at least one of the two compacting sheets. The antiskid layer is arranged at the inner side of the compacting sheets of the thread tensioning device provided by the invention; friction force between the two compacting sheets and an upper thread clamped in the middle is increased; the stability of the thread tensioning device towards the tension regulation of the upper thread is improved; control force towards the upper thread, particularly the control force towards a finer upper thread, is enhanced; and the smoothness and the attractive appearance of a sewing track are guaranteed better.
Description
Technical field
The present invention relates to a kind of thread tensioner for sewing machine, relate in particular to a kind of dependence and regulate the stable type turnbuckle of two clamping pieces apart from control sewing machine surface thread degree of tightness.
Background technology
Usually, Sewing machines cooperates through the eedle of needle plate top and the rotating shuttle of needle plate below, and upper thread and bottom line are combined, and on lining, forms the seam mark.During Sewing machines work, need to regulate the tension force of upper thread and bottom line, to guarantee the smooth, attractive in appearance of seam mark.At present, the tension force of sewing machine surface thread mainly is to regulate through the turnbuckle with nut and spring cooperating.Through the turn nut, the compression spring reduces the distance between two clamping pieces that turnbuckle is used for clamping upper thread, realizes the adjusting of opposite line tension.Contact-making surface between two clamping pieces is comparatively smooth usually, and suture is very thin again, and is non-slip when being difficult to guarantee to compress near increase pressure, and it is unstable to make line tension regulate easily.
Summary of the invention
The present invention has overcome the deficiency of prior art, provides a kind of simple in structure, increases the frictional force of turnbuckle clamping piece to upper thread, is prone to regulate, and is non-slip, the thread tensioner for sewing machine of good stability.
For achieving the above object; The technical scheme that the present invention adopts is: a kind of thread tensioner for sewing machine comprises axis and is placed in two annular clamping pieces on the axle, i.e. first clamping piece; Second clamping piece; Said two clamping pieces are oppositely arranged, and described first clamping piece outside is provided with hold down gag, and it is characterized in that: the inboard of at least one is provided with skid resistant course in said two clamping pieces.
In preferred embodiment of the present invention, comprise that further said skid resistant course covers the middle part of place clamping piece inner surface, promptly said axis neighboring area at least.
In preferred embodiment of the present invention; Comprise that further said hold down gag is tension nut assembly or electromagnet assembly; Said electromagnet assembly comprises the iron core that is arranged on first clamping piece outside and is around in the coil on the iron core; Described second clamping piece and first clamping piece laterally arrange, and have magnetic.
In preferred embodiment of the present invention, comprise that further said skid resistant course covers the whole inner surface of place clamping piece.
In preferred embodiment of the present invention, the thickness that further comprises said skid resistant course is the 1%-10% of appended clamping piece thickness.
In preferred embodiment of the present invention, comprise that further said skid resistant course is felt, rubber or plastic material.
The invention solves the defective that exists in the background technology; Turnbuckle clamping piece of the present invention inboard is provided with skid resistant course; Increase two clamping pieces with the frictional force between the intercalary upper thread, improve the stability that turnbuckle opposite line tension is regulated, strengthen control it; Especially to control, better guarantee the smooth, attractive in appearance of seam mark than the fine flour line.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is the structural representation of the preferred embodiments of the present invention;
Among the figure: 1, upper thread, 2, axis, 4, first clamping piece, 6, second clamping piece, 8, skid resistant course, 10, hold down gag.
The specific embodiment
Combine accompanying drawing and embodiment that the present invention is done further detailed explanation now, these accompanying drawings are the sketch map of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
As shown in Figure 1, thread tensioner for sewing machine of the present invention comprises axis 2 and is placed in two the annular clamping pieces of axle on 2, i.e. first clamping piece, 4, the second clamping pieces 6, and said two clamping pieces are oppositely arranged, and two clamping piece inboards are provided with skid resistant course 8.Described first clamping piece 4 outsides also are provided with hold down gag 10.Said skid resistant course 8 covers the whole inner surface of place clamping pieces, and thickness is the 1%-10% of appended clamping piece thickness, and skid resistant course 8 adopts the material that can increase the clamping piece skin-friction coefficient, felt for example, rubber, foam or plastics PET, PVC, PP.Said hold down gag 10 is an electromagnet assembly; Said electromagnet assembly comprises the iron core that is arranged on first clamping piece, 4 outsides and is around in the coil on the iron core; Described second clamping piece 6 and first clamping piece 4 laterally arrange, and process for magnetic material, for example iron, cobalt, nickel.
Before using Sewing machines to begin the work of making, upper thread 1 is walked around turnbuckle axis 2 of the present invention, regulate electric current in the said electromagnet coil; Change magnetic field intensity; Adjust the pressure of two pressure strip centering top-stitchings 1, utilize said electromagnet hold down gag 10, pressure strip can make it more accurate through the control size of current to the adjusting of upper thread 1 pressure; Skid resistant course 10 then improves coefficient of friction, guarantees that upper thread 1 is more stable.
Above foundation desirable embodiment of the present invention is enlightenment, and through above-mentioned description, the related personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification, must confirm technical scope according to the claim scope.
