Description
Technical field
The invention belongs to the sewing machine technique field, relate to a kind of line haulage gear that stretches tight, particularly a kind of line haulage gear that stretches tight of four pins, six line sewing machines.
Background technology
The line that stretches tight in the Sewing machines stitching is the decorative thread that the cloth upper surface increases in becoming the seam process, and it is to be woven mutually to form with many pieces of eedles by the Wrapping implement traction to be covered in the cloth surface.In three pins, five line flat seaming machines, the line Wrapping implement that stretches tight is one piece of pin that stretches tight, and this pin that stretches tight swings with linear fashion under the drive of driving mechanism, and the standard pendulum momentum is 17mm.This pin that stretches tight is applied on the sewing machine of four pins, six lines, because four suture needle spacings are widened, the oscillating quantity of pin of stretching tight also will correspondingly increase, and a side of four suture needles of sewing machine is provided with the corner cut protective sheet, cause sewing machine self space to reduce, the pin amplitude of oscillation that stretches tight is restricted, and therefore the Yarn tightening machine structure of three pins, five line flat seaming machines can not meet the demands.
Summary of the invention
The present invention is directed to existing technology and have the problems referred to above, proposed a kind of line haulage gear that stretches tight of four pins, six line sewing machines, the amplitude of fluctuation of this line haulage gear that stretches tight is little, the little and processing safety height of working space.
The present invention realizes by following technical proposal: a kind of line haulage gear that stretches tight of four pins, six line sewing machines, be arranged on the presser feet, it is characterized in that, this line haulage gear that stretches tight comprises bearded needle, line carriage and fanning strip stretch tight, described fanning strip is coupling on above-mentioned presser feet, on presser feet, also be provided with first rotating shaft and second rotating shaft, the affixed bearded needle in the lower end of first rotating shaft, the affixed line carriage that stretches tight in the lower end of second rotating shaft, be provided with between the upper end of described first rotating shaft and second rotating shaft and the above-mentioned fanning strip can drive bearded needle and stretch tight the line carriage stagger the swing linkage.
Drive the fanning strip swing by actuating unit, when fanning strip rotates counterclockwise, drive first rotating shaft and second rotating shaft rotates counterclockwise by linkage, bearded needle is that arrange outside suture needle in the axle center with first rotating shaft, and the line carriage that stretches tight is with second rotating shaft that the axle center is swung in suture needle close, and in this process, bearded needle catches on the line that stretches tight makes the line that stretches tight stretching, the line carriage that the stretches tight line that will stretch tight is shifted the suture needle inboard onto, and suture just interweaved with the line that stretches tight after cloth was passed in suture needle.Actuating unit drives fanning strip and swings clockwise, and the line carriage that stretches tight is that arrange outside suture needle in the axle center with second rotating shaft, and the line that stretches tight of back is pulled out, and bearded needle is with first rotating shaft that the axle center swing in suture needle close, so circulates, and the line that stretches tight is woven on the suture.The line haulage gear replaces the pin straight line swing of singly stretching tight of three pins, five line flat seaming machines with the swing of stretch tight line carriage and bearded needle owing to originally stretch tight, so can reduce oscillating quantity, and working space is little, satisfies the oscillating quantity of four pins, six line sewing machines.
In the line haulage gear that stretches tight of above-mentioned four pins, six line sewing machines, the described front end that stretches tight the line carriage is provided with a cable-through hole, is provided with a tension disc on the line carriage that stretches tight of cable-through hole inboard, is provided with the U-lag of an indent on the line carriage that stretches tight between cable-through hole and the tension disc.Cable-through hole is used to wear the line that stretches tight, and the line that stretches tight enters into other mechanisms through tension disc after passing cable-through hole, like this, the U-lag of line and the indent of stretching tight forms an annulus, this annulus be in along with stretching tight line carriage swing suture needle under, after suture needle fell, the line that stretches tight will be positioned at the rear side of suture needle.Owing on the line carriage that stretches tight with cable-through hole and tension disc U-lag is set, make the aperture of annulus become big, so suture needle is not easy to occur bouncing pilotage, the raising sewing quality.
In the line haulage gear that stretches tight of above-mentioned four pins, six line sewing machines, described tension disc working face is the V-arrangement of indent.The line that stretches tight can be buckled on the working face of tension disc after stretching by bearded needle, and in the swing process of line carriage that stretches tight, the line that stretches tight slides to the V-arrangement bottom of indent along V-arrangement, thereby the line that will stretch tight imports on the bearded needle, also is beneficial to suture needle simultaneously and passes the line that stretches tight, and improves sewing quality.
In the line haulage gear that stretches tight of above-mentioned four pins, six line sewing machines, the position of described cable-through hole is higher than the V-arrangement lowest part position of tension disc.The line that stretches tight forms incline direction through the V-arrangement lowest part after passing cable-through hole, makes things convenient for bearded needle to catch on the line that stretches tight.
In the line haulage gear that stretches tight of above-mentioned four pins, six line sewing machines, the front end of described bearded needle is provided with overhead kick, and the end points of front end slips into the skew surface of overhead kick to the smooth easy guiding line that stretches tight is set between the overhead kick.
In the line haulage gear that stretches tight of above-mentioned four pins, six line sewing machines, described linkage comprises first curved arm rod that is connected as a single entity with first rotating shaft, second curved arm rod that is connected as a single entity with second rotating shaft, first drive link and second drive link, one end of first drive link is coupling on first curved arm rod, the other end is coupling on a side covering of the fan of fanning strip, angle between first drive link and first curved arm rod is the obtuse angle, one end of second drive link is coupling on second curved arm rod, the other end is coupling on the opposite side covering of the fan of fanning strip, and the angle between second drive link and first curved arm rod is an acute angle.
In the line haulage gear that stretches tight of above-mentioned four pins, six line sewing machines, described fanning strip is provided with the open slot that is used to connect actuating unit.Actuating unit is common actuating unit, is used to stir the fanning strip swing.
Compared with prior art, the present invention has following advantage:
1, the present invention replaces the straight line swing with rotary oscillation, and the oscillating quantity of the line carriage that stretches tight reduces, and working space is little, has satisfied the oscillating quantity of four pins, six line sewing machines.In addition, because the minimizing of oscillating quantity, the wearing and tearing between the machinery reduce, and service life is elongated.
2, the line carriage that stretches tight of the present invention is provided with U-lag, and line wearing and tearing and reduce the situation of suture needle wire jumper can prevent to stretch tight.The tension disc of band V-arrangement working face and the skew surface on the bearded needle import in the overhead kick in the bearded needle line that stretches tight easily, and the shaping of the stable line that stretches tight improves sewing quality.
3, the line carriage that stretches tight of the present invention is swung in less space, therefore, even under the loosening situation of the line that stretches tight, the braiding of also can realize stretching tight line and suture.
