Specific embodiment：
The utility model is further described with specific embodiment below, referring to Fig. 1-6：
A kind of sewing machine tangent line blowing structure includes Concealed side cutter 1, presser feet cauda 2, presser feet 3, the presser feet tail
Gas-tpe fitting 4 and the 1-3 blowing pipes 5 being arranged in parallel are provided on piece 2, the outlet air end of blowing pipe 5 is air outlet 6, is gone out
Air port 6 is corresponding with 7 position of air entry of suction line on Concealed side cutter 1, and gas-tpe fitting 4 is connected with blowing pipe 5, with
Point on 5 axis of blowing pipe is origin, using the left and right directions of presser feet cauda 2 as X-axis, using the front-rear direction of presser feet cauda 2 as Z
Axis establishes three-dimensional system of coordinate, and the angle α between the axis of the blowing pipe 5 and the X-axis of three-dimensional system of coordinate is 10-50 °, described
The axis of blowing pipe 5 is located at X, the fourth quadrant of Z coordinate, between the axis of the blowing pipe 5 and the Y-axis of three-dimensional system of coordinate
Angle β for 40-80 °, the axis of the blowing pipe 5 is located at X, the third quadrant of Y-coordinate.The angle α, folder of the utility model
Angle beta can in corresponding scope arbitrary value.
Further, the air outlet 6 to the distance between Concealed side cutter 1 is 5-15mm.Distance usually outlet air
It mouthfuls 6 center, can arbitrary value within the above range the distance between to Concealed side cutter 1.Distance is too small, it is impossible to blow to
Line pigtail, distance is too big, and wind-force can dissipate, and can not form one power, and line pigtail is blown into the air entry 7 of Concealed side cutter 1.
Further, 1-3 5 collective effect of blowing pipe makes the wind-force of air blowing fall in the range of air draught.The utility model
It is preferred that the blowing pipe 5 is one.
Further, a diameter of 0.5-4mm of the blowing pipe 5.Diameter, wind-force is inadequate, and diameter is too big, noise
It is excessive.The diameter range of the utility model can make noise match with wind-force, in the case where ensureing certain wind-force, noise
In rational scope.
For the utility model by said structure, it is shorter to cut rear line pigtail, realizes real short-term pigtail, can reach after cutting
Line pigtail is less than the desired value of 5mm, without carrying out artificial thread chain trimming again after sewing, greatly improves work efficiency, reduces
Human cost, trimming effect are good.
In order to suitably adjust air blowing angle, the utility model is provided with adjustment hole 8 on presser feet cauda 2, which can
To be that bar hole can also be round hole, bar hole is laterally set, and presser feet cauda 2 is mounted on presser feet by screw through adjustment hole
On 3.The gas that can blow out presser feet cauda 2 by adjusting air blowing angle preferably falls the air draught scope 9 in Concealed side cutter 1
It is interior.
In addition, the front end of presser feet cauda 2 described in the utility model is arranged on presser feet 3, rear end is vacantly set, presser feet tail
The overhanging portion of piece 2 has been upwardly formed anti-compress concave station 10.
For sewing machine when carrying out sewing work, feed dog 12 does elliptic motion, and periodically keeps contacting with presser feet 3.
The effective range of feed dog 12 can not be generated with the anti-compress concave station 10 of presser feet cauda 2 and contacted in the lower section of presser feet 3.It is using
When, the gas-tpe fitting 4 is connected with positive pressure devices；The suction line of the Concealed side cutter 1 is connected with negative pressure device.Positive pressure
Device is blown, negative pressure device air-breathing.The end of a thread is blown into air entry 7 by positive pressure devices, and is carried out tangent line by Concealed side cutter 1 and returned
It receives.
After cloth enters presser feet 3, under the collective effect of feed dog 12 and presser feet 3, cloth moves forward, when cloth takes off
When tripping foot and feed dog 12, due to the presence of anti-compress concave station 10, cloth can easily depart from presser feet cauda 2, and trimming is smooth
It carries out.
Anti- compress concave station 10 can make the utility model for processing the cloth of different-thickness, particularly heavy duck material, fit
It is wide with scope.When cloth departs from presser feet 3 so that cloth can be easily disengaged from presser feet cauda 2, and it is tight to efficiently solve cloth
The phenomenon that being pressed on needle plate 11.
The utility model can also finely tune front and rear shifting of the presser feet cauda 2 compared with presser feet 3 by above-mentioned adjustment hole 8
It is dynamic, adjustable range 0.2-1.5mm.Specific numerical value can be according to actual conditions arbitrary value within the above range.
Specifically, the distance H of baseplane of the baseplane of the anti-compress concave station 10 to presser feet cauda 2 is 0.5-2mm.Tool
The numerical value of body can be according to actual conditions arbitrary value within the above range.
In order to make assembling more convenient, the baseplane of the presser feet cauda 2 is vertically provided with anti-rotation boss 13, anti-rotation boss
13 are set in left-right direction, and anti-rotation boss 13 is located at the rear side of presser feet 3.The width of anti-rotation boss 13 is less than or equal to presser feet cauda
2 width.By anti-rotation boss 13, the utility model can lean on a screw that just presser feet cauda 2 can be fixed on presser feet 3.
It is of course also possible to not select the structure of anti-rotation boss 13, presser feet cauda 2 is directly fixed on presser feet with two screws
On 3.
Above-described embodiment is only one of preferred embodiment of the utility model, and the implementation of the utility model is not limited with this
Scope, therefore：The equivalence changes that all shapes, structure, principle according to the utility model are done should all be covered by the guarantor of the utility model
Within the scope of shield.
