Transition point 7 divides the second guiding curl 5 for guide edge 10 and the second outer guide edge 11 in second, and guide edge 8 projects extremely in first
Curve in second plane is the first drop shadow curve, and the first drop shadow curve is located in the second outer guide edge 11, guide edge in second
10 projections to the curve in the first plane is the second drop shadow curve, and the second drop shadow curve is located in the first outer guide edge 9.
In the present embodiment, work feed guiding device is combination wheel construction, and combination wheel construction includes first pulley 13, the second band
Wheel 14 and flexible-belt 15, first pulley 13 and the second belt wheel 14 are rotatably connected in pressure foot 1, and 15 sets of flexible-belt in first band
Outside wheel 13 and the second belt wheel 14, the outer surface of flexible-belt 15 is work feed curved surface 3, the edge line difference of outer surface two of flexible-belt 15
For the first guiding curl 4 and the second guiding curl 5.
Cloth is processed with sewing under presser feet and is moved forward, in 15 rotation process of flexible-belt, when 15 two sides of flexible-belt
First guiding curl 4 and second guiding curl 5 and cloth vertical range difference when, pressure of 15 two sides of flexible-belt to cloth
Difference, so that 15 two sides of flexible-belt are inconsistent to the frictional force of cloth, the small side deflection of cloth Forward Shi Huixiang frictional force, i.e.,
It is deflected to the big side of cloth vertical range, when the first guiding curl 4 of 15 two sides of flexible-belt and the second guiding curl 5 and cloth
When the vertical range of material is identical, cloth moves forward along straight line.
As shown in figure 14, after the rotation of the completion one week of flexible-belt 15, cloth completes the Forward of a cycle, and cloth therewith
Forward track is wave line tracking, so that automated sewing produces wave track on sewing machine.In wave in a cycle
The perimeter of length L and flexible-belt 15 is positively correlated, and the difference of depth H and the vertical range of 15 two sides of flexible-belt to cloth is positively correlated.
As shown in figs. 2 to 4, combination wheel construction further includes I-shaped connecting rod, and I-shaped connecting rod includes the first wheel shaft 17, the second wheel shaft
18 and connecting rod 19,19 both ends of connecting rod be fixedly connected respectively in the middle part of the first wheel shaft 17 and the second wheel shaft 18, two first bands
Wheel 13 is rotatably connected on 17 both ends of the first wheel shaft respectively, and two the second belt wheels 14 are rotatably connected on 18 both ends of the second wheel shaft respectively,
A threaded hole 20 is respectively provided in first wheel shaft, 17 both ends of the surface, by the threaded connection of screw 21 and threaded hole 20 will combine wheel construction and
Pressure foot 1 is fixed.Structure setting is simple, convenient for disassembly and assembly, by changing the length of connecting rod 19 and matching flexibility being arranged
With 15 length, so as to facilitate the perimeter for adjusting flexible-belt 15, to adjust the length L of wave.
First pulley 13 and the second belt wheel 14 are equal in magnitude, easy to make.
Flexible-belt 15 is rubber material, convenient for production.
As shown in Fig. 5~6, multiple sawtooth 16 are equipped on 15 outer surface of flexible-belt.
As shown in fig. 6, each sawtooth 16 is formed by bending arcuation sawtooth to same direction.
By the setting of sawtooth 16, it is capable of increasing the frictional force that flexible-belt 15 is contacted with cloth, cloth is avoided to advance
It skids in journey, so that cloth more smoothly moves forward, and sawtooth 16 is arranged to arcuation sawtooth, guaranteeing the smooth Forward of cloth
When, so that the wave line tracking of cloth Forward is more uniform consistent.
Embodiment two
As shown in Fig. 7~8, the present embodiment provides a kind of sewing-machine foots for sewing wave line tracking, in embodiment one
The difference is that work feed guiding device is single-turn wheel construction, single-turn wheel construction includes being rotatably connected in pressure foot 1 to turn
The outer peripheral surface of wheel 12, runner 12 is work feed curved surface 3, and two edge lines of the outer peripheral surface of runner 12 are respectively the first guiding curl 4
With the second guiding curl 5.
Cloth under presser feet as sewing processing moves forward, in 12 rotation process of runner, when the of 12 two sides of runner
When one guiding curl 4 and the second guiding curl 5 and the vertical range difference of cloth, 12 two sides of runner are different to the pressure of cloth,
So that 12 two sides of runner are inconsistent to the frictional force of cloth, and the small side deflection of cloth Forward Shi Huixiang frictional force, i.e. Xiang Yubu
The big side deflection of vertical range is expected, when the first guiding curl 4 of 12 two sides of runner and the second guiding curl 5 are vertical with cloth
Apart from it is identical when, cloth along straight line move forward.
As shown in figure 9, this is the side view in a kind of rotation process of single-turn wheel construction, at this point, 12 left side of runner and cloth
The vertical range of material is less than the vertical range on right side and cloth, and cloth can deflect to the right.
As shown in Figure 10, this is the side view in another rotation process of single-turn wheel construction, at this point, the left side of runner 12 with
The vertical range of cloth is equal with the vertical range of cloth with right side, at this point, cloth moves forward along straight line.
As shown in figure 11, this is the side view in another rotation process of single-turn wheel construction, at this point, the left side of runner 12 with
The vertical range of cloth is greater than the vertical range on right side and cloth, at this point, cloth can deflect to the left.
As shown in figure 14, after the rotation of the completion one week of runner 12, cloth completes the Forward of a cycle therewith, and before cloth
Shifting track is wave line tracking, so that automated sewing produces wave track on sewing machine.Length in wave in a cycle
The perimeter for spending L and runner 12 is positively correlated, and the difference of depth H and the vertical range of 12 two sides of runner to cloth is positively correlated.
Runner 12 is made of metal or plastics, and the runner 12 of unlike material is selected to add with the sewing for adapting to unlike material cloth
Work.
As shown in Figure 12~13, multiple sawtooth 16 are equipped on 12 outer peripheral surface of runner.
As shown in figure 13, each sawtooth 16 is formed by bending arcuation sawtooth to same direction.
By the setting of sawtooth 16, it is capable of increasing the frictional force that runner 12 is contacted with cloth, avoids cloth in advance process
Sawtooth 16 so that cloth more smoothly moves forward, and is arranged to arcuation sawtooth by middle skidding, in the smooth Forward of guarantee cloth,
So that the wave line tracking of cloth Forward is more uniform consistent.
Specific examples are applied in the present invention, and principle and implementation of the present invention are described, above embodiments
Illustrate to be merely used to help understand method and its core concept of the invention；At the same time, for those skilled in the art, according to
According to thought of the invention, there will be changes in the specific implementation manner and application range.In conclusion the content of the present specification
It should not be construed as limiting the invention.
