Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.

- Fig. 5 referring to Fig.1, a kind of automatic carriage, which is sent, backstitches drive mechanism under roller sewing machine, including backstitch pedestal 1, under backstitch and push away Moving axis 2 and electromagnet 3, one end that impeller-hub 2 is backstitched under described are fixedly connected with the axle center of electromagnet 3, and the electromagnet 3 can lead to Screw is crossed to be fixedly mounted in electromagnet fixing seat 4；The other end of impeller-hub 2 is backstitched under described by plastic cement shock-proof block 5 and is fallen It stitches pedestal 1 and contradicts connection, which has shockproof, cushioning effect；The pedestal 1 that backstitches passes through spring assembly and side Seat connection；It is backstitched under described and fixed holder assembly is installed on impeller-hub 2.In the present embodiment, using the above structure, assembler is allowed Or maintenance person can intuitively go to debug or repair this machine very much, overcome the covered difficulty in existing visual angle.

Specifically, the pedestal 1 that backstitches includes the first connecting plate 1-1 and the second connecting plate 1-2, the first connecting plate 1- 1 and second connecting plate 1-2 one bending be vertically arranged, set on the first connecting plate 1-1 close to one end of the second connecting plate 1-2 There is threaded hole a 1-11, the first connecting plate 1-1 to be equipped with a convex block 1-12 far from one end of the second connecting plate 1-2, it is described convex Block 1-12 is vertically arranged with the first connecting plate 1-1 one bending, and the convex block 1-12 backstitches impeller-hub 2 under and contradicts connection, this Sample backstitches impeller-hub 2 instantly and pushes when backstitching pedestal 1 of end, to generate the movement backstitched.

Specifically, the inside of the second connecting plate 1-2, which is equipped with stiffening plate a 1-21, the stiffening plate 1-21, is equipped with one For installing the first mounting hole 1-22 of universal sliding block 6, which makes it and falls for installing universal sliding block 6 When stitching pedestal mating reaction, to generate the movement backstitched.

Specifically, the spring assembly includes spring 7, spring stay hook 8 and is mounted on the first connecting plate 1-1 and screw thread First screw 9 of hole 1-11 connection, one end of the spring 7 are connect with the first screw 9, the other end and spring of the spring 7 Stay hook 8 connects；In the present embodiment, which is screwed on above-mentioned threaded hole 1-11, so during installation, so that bullet One end of spring 7 and 9 clasp joint of the first screw, the other end and 8 clasp joint of spring stay hook of spring 7.After the completion of backstitching, above-mentioned electricity The stopping of magnet 3 is had an effect, at this time under 7 pulling force effect of spring, so that backstitching 1 return of pedestal.

Specifically, one end that the spring stay hook 8 includes hook plate a 8-1, the hook plate 8-1 is equipped with and connect with spring 7 The other end of dog hole 8-2, the hook plate 8-1 be equipped with the second mounting hole 8-3 for connecting with side seat；In the present embodiment, above-mentioned Spring 7 and dog hole 8-2 clasp joint, and the second mounting hole 8-3 then passes through screw or bolt and connect with side seat, so that spring is fixed Hook 8 is fixed with side seat.

Specifically, the fixed holder assembly includes being socketed in down the first fixing seat 10 and second backstitched on impeller-hub 2 to consolidate Reservation 11, first fixing seat 10 and the setting of the second fixing seat 11 interval, first fixing seat 10 and the second fixing seat 11 Structure it is identical.In the present embodiment, while backstitching 2 transverse direction work of impeller-hub instantly, by first fixing seat 10 and second Fixing seat 11 is protected, it is ensured that under backstitch stability, durability of the impeller-hub 2 in axial movement.

Wherein, first fixing seat 10 includes the first fixed plate 10-1 and the second fixed plate 10-2, and described first is fixed Plate 10-1 and the second fixed plate 10-2 one bending are vertically arranged；The first fixed plate 10-1 is equipped with for backstitching under running through One through-hole 10-11, the second fixed plate 10-2 of impeller-hub 2 is equipped with a notch 10-21.In the present embodiment, through-hole The diameter of 10-11 backstitches the diameter of impeller-hub 2 under being slightly larger than, impeller-hub 2 is backstitched under being convenient in this way can run through through-hole 10- 11；Notch 10-21 is then used for bolt and connect with side seat, so that the second fixed plate 10-2 is fixed with side seat.

Working principle of the utility model is: the mechanics principle of lever is utilized, in existing technical foundation, by sticking point The installation point of electromagnet is laterally extended, and when machine needs to backstitch work, electromagnet is laterally contributed, while by being fixed on electricity The impeller-hub promotion end of magnet shaft in the heart backstitches pedestal, to generate the movement backstitched.After the completion of backstitching, electromagnet stops Only have an effect, at this time under spring tension effect so that backstitch pedestal return, then just complete one by become along seam backstitch again by Backstitch the process being returned to along seam.

In addition, it is necessary to illustrate, the structure and the prior art of the above-mentioned side seat being related to are without essential area in the present embodiment Not, since the side seat is also not the technology contents of the application focused protection.Therefore, the structure of side seat is no longer specifically described here.

In conclusion the automatic carriage send the drawbacks of backstitching drive mechanism under roller sewing machine, revolutionize existing design, give Assembling and setting and maintenance bring convenience.

The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model Within enclosing.
