Abstract
The invention relates to a cloth transmission and adjustment mechanism of a sewing machine, which comprises a machine head, a dial, a cloth transmission regulator, a regulator shaft, a connecting rod and an offsetting spring, wherein the shaft part of the dial passes through the machine head and is in butt joint with a groove of the cloth transmission regulator; the cloth transmission regulator is sequentially connected with the regulator shaft and the connecting rod, and the other end of the cloth transmission regulator is connected with the offsetting spring; a shaft surface of the dial is provided with a blocking rod in a penetrating way; a pull rod is fixed at one side of the blocking rod; the pull rod passes through the peripheral surface of the dial and can move along the axial direction of the dial; and a through hole is arranged at the side of the machine head. By matching the pull rod, the blocking rod and the through hole, the cloth transmission and adjustment mechanism of the sewing machine enables the cloth transmission quantity to be stable and the cloth transmission performance to be reliable; and the position of the dial can be freely rotated within the range of a circle, so that stepless regulation can be realized.
Description
Technical field
The present invention relates to a kind of accessaries of sewing machine, relate in particular to a kind of Sewing machines work feed governor motion.
Background technology
Sewing machines is with one or how with sewing thread, on cloth, forms one or more stitchings, the machine that makes one or more layers cloth interweave or unite by a seam.The cloth-feeding device of existing Sewing machines is the displacement that realizes cloth through the scale of regulating bidding quotation, and bidding quotation is installed in the head, and the back side of bidding quotation has locating slot, and the alignment pin that is with spring is installed in the installing hole of head.When rotating bidding quotation, alignment pin is not just to drop in the locating slot of needle gage bidding quotation sometimes, but starts from the inclined-plane or the top of locating slot, will appear at the problem that depart from gradually Sewing machines operation process mid-cut bidding quotation position.Though the needle gage bidding quotation shows identical position, causes cloth feed amount inconsistent, does not reach and makes requirement.
Summary of the invention
The present invention has overcome the deficiency of prior art, and a kind of Sewing machines work feed governor motion of simple in structure, dependable performance is provided.
For achieving the above object; The technical scheme that the present invention adopts is: a kind of Sewing machines work feed governor motion, comprise head, dial, work feed adjuster, regulator shaft, connecting rod and back-moving spring, and said dial axial region runs through the groove butt of head and work feed adjuster; Said work feed adjuster is connected with regulator shaft, connecting rod successively; The other end is connected with back-moving spring, and the axial plane of said dial is equipped with kelly, and a side of said kelly is fixed with pull bar; Said pull bar passes the side face of said dial and along the moving axially of said dial, the side of said head has through hole.
In preferred embodiment of the present invention, Sewing machines work feed governor motion comprises that further said kelly is tapered near an end of said head.
In preferred embodiment of the present invention, Sewing machines work feed governor motion comprises that further said pull bar is T-shaped.
In preferred embodiment of the present invention, Sewing machines work feed governor motion comprises that further the groove of said work feed adjuster is V-shaped.
The invention solves the defective that exists in the background technology, the present invention cooperates with through hole through pull bar, kelly, makes the stable and dependable performance of cloth feed amount, and the dial position can be rotated arbitrarily in all scopes, realizes step-less adjustment.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is the structural representation of the preferred embodiments of the present invention;
Among the figure: 1, head, 2, dial, 3, the work feed adjuster, 4, regulator shaft, 5, connecting rod, 6, back-moving spring, 7, groove, 8, kelly, 9, pull bar, 10, through hole.
The specific embodiment
Combine accompanying drawing and embodiment that the present invention is done further detailed explanation now, these accompanying drawings are the sketch map of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
As shown in Figure 1; A kind of Sewing machines work feed governor motion comprises head 1, dial 2, work feed adjuster 3, regulator shaft 4, connecting rod 5 and back-moving spring 6, and said dial 2 axial regions run through groove 7 butts of head 1 and work feed adjuster 3; Said work feed adjuster 3 is connected with regulator shaft 4, connecting rod 5 successively; The other end is connected with back-moving spring 6, and the axial plane of said dial 2 is equipped with kelly 8, and a side of said kelly 8 is fixed with pull bar 9; Said pull bar 9 passes the side face of said dial 2 and along the moving axially of said dial 2, the side of said head 1 has through hole 10.
In the through hole 10 on the kelly 8 insertion heads 1, said kelly 8 is tapered near an end of said head 1.The preferred said pull bar of the present invention 9 is T-shaped, is convenient to pull bar 9 and drives kellies 8 and move.
The groove 7 of the preferred said work feed adjuster 3 of the present invention is V-shaped.
Operation principle of the present invention is following:
Rotary dial 2, the front end of its axial region touches work feed adjuster 3, and the obliquity of control work feed adjuster 3 is connected on the cloth feeding mechanism through connecting rod 5 again, confirms the transportation load of cloth feeding mechanism, thereby regulates cloth feed amount.When keeping cloth feed amount, pulling pull bar 9 drives kelly 9 and moves towards head 1, and the tapering point of kelly 9 is snapped in the through hole 10 of head 1, and dial 2 can't rotate, and can not depart from.
Above foundation desirable embodiment of the present invention is enlightenment, and through above-mentioned description, the related personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification, must confirm technical scope according to the claim scope.
