The other end for stating tugboat frame is connected on presser feet arm, and the bogie is fixed on feeding retainer, the bias half of the drive rod
Major axis radius of the footpath more than the elliptical trajectory of feeding retainer.
In a kind of above-mentioned synchronization feeding device, between the rear tugboat and drive rod unilateral bearing is provided with.
In a kind of above-mentioned synchronization feeding device, the rear tugboat, drive rod and unilateral bearing are arranged concentrically.
In a kind of above-mentioned synchronization feeding device, the other end of the drive rod is provided with connecting plate, on connecting plate
It is provided with connecting pin, connecting pin and drive rod eccentric setting.
In a kind of above-mentioned synchronization feeding device, the bar-shaped trough is located at the upper end of bogie, and for open slot, drives
The lower end of frame is fixed on feeding retainer.
It is a further object to provide a kind of sewing machine, including a kind of synchronization feeding device as above.
Compared with prior art, the present invention has advantages below:
1st, rear tugboat of the invention moves up and down together with presser feet arm, presser feet, reduces the feeding step of operative employee, without the need for
One independent power source drive cloth-dragging wheel is set in addition, cost is reduced, efficiency is improve.
2nd, rear tugboat of the invention and feed mechanism are driven by feeding retainer, the feeding synchronization before and after realizing, it is to avoid
In prior art because sewer drawing material, feeding is incorrect the inaesthetic phenomenon of stitching occurs, realize and main feeding retainer
Complete Synchronization work feed, it is ensured that the aesthetic property of stitching of the sewing after sewing.

Specific embodiment
The following is the specific embodiment of the present invention and combine accompanying drawing 1-4, technical scheme is further retouched
State, but the present invention is not limited to these embodiments.
As shown in Figure 1, 2, 3, a kind of synchronization feeding device, includes the rear tugboat 2 for being arranged on the rear end of presser feet 1, rear tugboat 2
It is arranged on drive rod 3, around the one-directional rotation of drive rod 3, one end of drive rod 3 is connected to one end of tugboat frame 4 to the rear tugboat 2
The upper, other end is provided with the connecting pin 5 with the eccentric setting of drive rod 3, and connecting pin 5 is arranged in the bar-shaped trough 7 of bogie 6 and realizes
The intermittent one-directional rotation of tugboat 2 afterwards, the other end of the tugboat frame 4 is connected on presser feet arm 8, and the bogie 6 is fixed on
On feeding retainer 9.Specifically connected mode is:Two screwed holes are provided with presser feet arm 8, correspondingly, in the another of tugboat frame 4
One end is provided with two installing holes, and screw is screwed onto in screwed hole through corresponding installing hole realizes tugboat frame 4 with presser feet arm 8
Connection.
In addition, the bar-shaped trough 7 is located at the upper end of bogie 6, and for open slot.And the lower end of the inwall of bogie 6 is arranged
There is step surface 10, step surface 10 is resisted against on the baseplane of feeding retainer 9, and bogie 6 is fixed by screws in feeding retainer 9
On.
The eccentric arm of drive rod of the present invention 3 is more than the major axis radius of the elliptical trajectory of feeding retainer 9, mesh
Be to realize that drive rod 3 swings back and forth.
As shown in figure 4, the conventional means for making the one-directional rotation of rear tugboat 2 is to arrange unilateral bearing.Therefore, tugboat in the rear
Unilateral bearing 11 is provided between 2 and drive rod 3.It is of course also possible to machinery of the tugboat 2 toward a direction after by arranging restriction
Structure is realizing one-directional rotation.Comparatively speaking, unilateral bearing 11 has simple structure, convenient advantage is realized, as this enforcement
Example it is preferred.
In addition, when mounted, the rear tugboat 2, drive rod 3 and unilateral bearing 11 are arranged concentrically.
The drive rod 3 of the present embodiment and being achieved in that for the eccentric setting of connecting pin 5:In the other end of the drive rod 3
Connecting plate 12 is provided with, connecting pin 5, connecting pin 5 and the eccentric setting of drive rod 3 are provided with connecting plate 12.
It is a further object to provide a kind of sewing machine, including a kind of synchronization feeding device as above.
The operation principle of the present invention:
When sewing machine works, main shaft drives feeding retainer 9 is moved, and the bogie 6 on feeding retainer 9 is by feeding
Retainer 9 drives the connecting pin 5 of motion, drive rod 3 to be arranged in the bar-shaped trough 7 of bogie 6, due to the motion rail of feeding retainer 9
Mark is ellipse, and the eccentric throw between drive rod 3 and connecting pin 5 more than the major axis of the elliptic motion trace of feeding retainer 9
Radius, so that drive rod 3 swings back and forth, is cased with a unilateral bearing 11 outside drive rod 3, the outer ring of unilateral bearing 11 is furnished with
Tugboat 2 afterwards, so as to tugboat 2 does intermittent one-directional rotation after realizing.
When sewing puts into the lower section of presser feet 1, presser feet 1 is up moved in the presence of presser foot lifting device, and presser feet arm 8 is past
During upper lifting, while also up move with the rear tugboat 2 being connected on presser feet arm 8 by tugboat frame 4 being pressed in presser feet 1
Firmly while sewing after tugboat 2 also move down therewith and push down sewing.Because master send tooth to be driven by feeding retainer 9, then
The action of tugboat 2 is also to be driven by feeding retainer 9, therefore, rear tugboat 2 send tooth to be synchronized with the movement with master.
