Summary of the invention:
The object of this invention is to provide that a kind of assembling and setting is simple, Assembly part is few, obvious minimizing " Bird's Nest " and play the novel thread-moving device of seam empty needle phenomenon.
The present invention is achieved in that
A novel thread-moving device, includes cylinder, and the motion bar of cylinder is connected with and is dialled line bar by adapter, cylinder is fixed on cylinder clamping piece, cylinder clamping piece is connected with mounting bracket, and the angle between cylinder clamping piece and mounting bracket is adjustable, and mounting bracket is for being connected cylinder with casing.
Above-mentioned mounting bracket is L-shaped, is provided with the installing hole for being connected with casing on vertical portion, and one end of horizontal part is connected with one end of cylinder clamping piece, and angle between cylinder clamping piece and horizontal part is adjustable.
Above-mentioned cylinder clamping piece includes upper clamping block and lower clamp, and upper clamping block and lower clamp are connected cylinder clamping between upper clamping block and lower clamp, and lower clamp is connected with one end of horizontal part, and the angle between lower clamp and horizontal part is adjustable.
One end of above-mentioned horizontal part and one end of lower clamp are respectively arranged with through hole, between horizontal part and lower clamp, are connected with nut by screw.
Above-mentioned installing hole is bar hole.
The above-mentioned lower end of dialling line bar in the shape of a spiral.
The advantage that the present invention gives prominence to is compared to existing technology:
1, the lower end of of the present invention group of line bar in the shape of a spiral, will be clamped in helical form in group line action rear wires, thereby has effectively prevented a seam off-line;
2, the bar hole on mounting bracket of the present invention is convenient to regulate the left and right position of thread-moving device on head, and then regulates the position of dialling line bar;
3, mounting bracket of the present invention and lower clamp can rotate mutually, therefore can be used for adjusting group line angle degree;
4, cylinder clamping of the present invention, between upper clamping block and lower clamp, can make cylinder carry out the adjustment of front and back position, thereby controls the relative distance of dialling between line bar and eedle;
5, the present invention is simple in structure, and assembling and setting is simple, and Assembly part is few, assembly tool, auxiliary material reduce or need not, reduce man-hour;
6, the present invention has more significantly and has reduced " Bird's Nest " phenomenon, thereby has promoted sewing thread trace quality.
Brief description of the drawings:
Fig. 1 is one of schematic perspective view of the present invention;
Fig. 2 is two of schematic perspective view of the present invention.
Detailed description of the invention:
With specific embodiment, the invention will be further described below, referring to Fig. 1-2:
A kind of novel thread-moving device, include cylinder 1, the motion bar 2 of cylinder 1 is connected with and is dialled line bar 4 by adapter 3, cylinder 1 is fixed on cylinder clamping piece 5, cylinder clamping piece 5 is connected with mounting bracket 6, angle between cylinder clamping piece 5 and mounting bracket 6 is adjustable, and mounting bracket 6 is for being connected cylinder 1 with head.
Above-mentioned mounting bracket 6 is L-shaped, is provided with the installing hole 12 for being connected with head on vertical portion 7, and one end of horizontal part 8 is connected with one end of cylinder clamping piece 5, and angle between cylinder clamping piece 5 and horizontal part 8 is adjustable.
Above-mentioned cylinder clamping piece 5 includes upper clamping block 9 and lower clamp 10, upper clamping block 9 and lower clamp 10 are connected cylinder 1 are clamped between upper clamping block 9 and lower clamp 10, lower clamp 10 is connected with one end of horizontal part 8, and the angle between lower clamp 10 and horizontal part 8 is adjustable.Upper clamping block 9 is connected by screw with lower clamp 10.Between upper clamping block 9 and lower clamp 10, be formed with cylinder installation position, cylinder 1 is arranged in cylinder installation position.Cylinder 1 is also adjustable with the position on lower clamp 10 at upper clamping block 9, regulates, thereby control the relative distance of dialling between line bar 4 and eedle 11 along the axial location of the motion bar 2 of cylinder 1.
One end of above-mentioned horizontal part 8 and one end of lower clamp 10 are respectively arranged with through hole, between horizontal part 8 and lower clamp 10, are connected with nut by screw.While regulating the angle between lower clamp 10 and horizontal part 8, unclamp nut, rotate lower clamp 10 and pass through again fastening nuts to the angle of needs, make lower clamp 10 after adjusting, not produce angle displacement with horizontal part 8.
Above-mentioned installing hole 12 is bar hole.Installing hole 12 is provided with two, and wherein 1 is the bar hole of an end opening.Installing hole 12 is convenient to regulate the left and right position of thread-moving device on head, and then regulates the position of dialling line bar 4.
Above-mentioned lower end of dialling line bar 4 in the shape of a spiral 13.Will be clamped in helical form 13 in group line action rear wires, thereby effectively prevent a seam off-line.
The action of the of the present invention group of line is by the linearly operating of cylinder control, accurately, fast.Due to design feature of the present invention, can carry out position adjustments, applicable to dialling line on various Sewing machiness multi-facetedly.
The present invention is arranged on head of sewing machine place, is fixed and is connected with head by mounting bracket 6, and upper and lower clamp 9,10 is clamped cylinder 1 by screw, then by adapter 3, cylinder 1 is connected with group line bar 4.
Driving lower end by the expanding-contracting action of cylinder 1 motion bar 2 is group line bar 4 of helical form 13, stretches out the upper thread on eedle is caught on, and upper thread will be clamped in the bar of helical form 17, thereby has effectively prevented a seam off-line; Mounting bracket 6 is provided with bar hole, can carry out simply the adjustment of position, left and right; Mounting bracket 6 can rotate mutually with cylinder clamping piece 5, therefore can be used for adjusting group line angle degree; The connected mode of cylinder clamping piece 5 and cylinder 1, makes cylinder 1 to carry out the adjustment of position in front and back, thereby controls the relative distance of dialling line bar 4 and eedle 11.
Above-described embodiment is only one of preferred embodiment of the present invention, not limits practical range of the present invention with this, therefore: all equivalences of doing according to shape of the present invention, structure, principle change, within all should being covered by protection scope of the present invention.
