Lower cutter is installed on seat；
The upper cutter connecting rod and lower cutter connecting rod also rotated with the rotating shuttle axle sleeve connection and the upper cutter and under
Cutter rotates corresponding with the position of center line of eedle to cutting edge lap position simultaneously.
Further, the adjustment pin include be sequentially connected and decentraction first to third shaft part, second shaft part
One end with the second shaft part respectively with one end of the upper cutter connecting rod, lower cutter connecting rod is hinged, the third shaft part and institute
Tangent line driving crank is stated to be fixedly connected.
Further, upper cutter swivel becket and incision swivel are further respectively had on the upper cutter connecting rod and lower cutter connecting rod
Rotating ring, the upper cutter swivel becket and the rotation of lower cutter swivel becket are set in the rotary shuttle shaft and put on.
The utility model has the beneficial effects that: lower cutter connecting rod drives incision when tangent line driving crank is swung
Tool apron and affixed lower cutter on it are rotated around the axis of rotating shuttle axle sleeve, and upper cutter connecting rod drives upper cutter seat and affixed
Upper cutter on it is rotated around the axis of rotating shuttle axle sleeve, and upper cutter and lower cutter are moved to the direction of eedle center line
It is dynamic, and at this moment upper cutter is left with lower cutter tangent line cutting edge position close to Chong Die progress tangent line at eedle center after tangent line
Remaining the end of a thread on cloth is shorter, and manual pruning the end of a thread is not necessarily to after tangent line, meanwhile, it is simple to operate, it is practical.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the installation site figure of the double acting knife cutting facility of the sewing machine of the utility model；
Fig. 2 is the structural schematic diagram of the double acting knife cutting facility of the sewing machine of the utility model；
Fig. 3 is the structural schematic diagram of the adjustment pin of the double acting knife cutting facility of the sewing machine of the utility model.
Specific embodiment
The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, to make the protection scope of the utility model apparent clear
Define.
Refering to fig. 1 shown in -2, the double acting knife cutting facility of the sewing machine of the utility model comprising:
Rotating shuttle axle sleeve 2 is fixed on casing 1；
Tangent line drives crank 3, is connected with external power source (not shown), and power source is for driving tangent line to drive
Crank 3 is swung, wherein one end of tangent line driving crank 3 is further fixed on adjustment pin 4；
Upper cutter connecting rod 5, one end are hinged in adjustment pin 4, and the other end is connected with upper cutter seat 6, on upper cutter seat 6
Upper cutter 7 is installed；
Lower cutter connecting rod 8, one end are hinged in adjustment pin 4, and the other end is connected with incision tool apron 9, on incision tool apron 9
Lower cutter 10 is installed；
Upper cutter connecting rod 5 and lower cutter connecting rod 8 also rotate connection and upper cutter 7 and lower cutter 10 with rotating shuttle axle sleeve 2 together
Shi Xuanzhuan is corresponding with the position of center line of eedle 11 to cutting edge lap position.
In the utility model, when tangent line driving crank 3 is swung, lower cutter connecting rod 5 drives incision tool apron 6 and affixed
