Nearly crossed beam trunking 11.
The moving knife guide 5 has two and extended along the longitudinal direction.Two described moving knife guides 5 pass through
Three bolts 203 are arranged on the inner side of two side of sidewall portion 12 and positioned at the top of stationary knife 2.So, two described moving knife guides
5th, pressure foot 1 and side of sidewall portion 12 constitute the guide groove 13 extended along the longitudinal direction.Two described moving knife guides 5, which are constituted, to be oriented to
The groove top of groove 13.The stationary knife 2 is fixedly mounted on the bottom land of the guide groove 13, and the moving knife 3 is located in guide groove 13, described
The top of moving knife 3 and the groove top sliding contact of guide groove 13, bottom and the top sliding contact of stationary knife 2, the moving knife 3 can be along guiding
The guiding of groove 13 slides back and forth.
The moving knife 3 is movably arranged as being connected on stationary knife 2 and with a drive mechanism, and the drive mechanism can drive dynamic
Knife 3 slidably reciprocates after stationary knife 2 is gone forward.In the present embodiment, the drive mechanism uses cylinder 7.The cylinder body of cylinder 7 leads to
The rear side that the 4th bolt 204 is fixedly installed on presser feet handle 9 is crossed, the middle part of the presser feet handle 9 offers the through hole 92 of front and rear insertion,
The piston rod 71 of the cylinder 7 is through through hole 92 and can do stretching motion along the longitudinal direction.The moving knife 3 passes through cylinder connector
8 are connected with the piston rod 71 of cylinder 7.Specifically, the top of the cylinder connector 8 passes through the 5th bolt 205 and piston rod 71
Front end be fixedly connected.The bottom of the cylinder connector 8 has on the pin-and-hole 81 of vertically insertion, the moving knife 3 and had upwards
The steady pin 33 of extension, the steady pin 33, which is penetrated, makes moving knife 3 be fixedly connected with cylinder 7 described in cylinder connector 8 in pin-and-hole 81
Piston rod 71 is elastic can to drive moving knife 3 to be slid back and forth on stationary knife 2.
The left and right sides of the moving knife 3 offers hook and slot 31 respectively, and the opening of the hook and slot 31 is towards the left and right sides of moving knife 3
Outside.The front portion of the moving knife 3 is formed with the curved end 32 of evagination, and both sides extend to hook and slot 31 to the curved end 32 to the left and right
Place.
On the pressure foot 1 that the rear portion of the making leaf spring 4 is fixed by the 6th bolt 206, the making leaf spring 4 have two to
The presser feet 41 of preceding stretching, two presser feets 41 or so are arranged side by side, the presser feet 41 is low early and high after and front portion of presser feet 41 be against it is dynamic
On knife 3, the front end of the presser feet 41 is dug upwards.
The moving knife 3 has the hook of the extended position being located between eedle 102 and the crossed beam trunking 11 of pressure foot 1 and moving knife 3
Tangent position of the groove 31 close to the blade 21 of stationary knife 2.When the forward slip of moving knife 3 to extended position, the energy of hook and slot 31 of the moving knife 3
The suture 104 of enough lower sections of pinprick 103 by the eedle 102 is hooked;When moving knife 3 is slided backward, the moving knife 3 will can be stitched
Line 104 is drawn to the position hook of stationary knife 2;When moving knife 3 returns to tangent position, moving knife 3 is pressed on by two described moving knife guides 5
The slip relative with the blade of stationary knife 2 of moving knife 3 is squeezed folder on stationary knife 2 and form shearing force by the suture between pressure foot 1 and moving knife 3
104 cut, and presser feet 41 and the moving knife 3 of the making leaf spring 4 clamp the suture 104 on the top of moving knife 3.
When flat seam machine in operation the present embodiment is sewed to sewing, controller can control suture 104 on sewing
The parallel suture path of two rows is formed, when seam line sewing is completed, shank 105, which is lifted, makes two eedles 102 are synchronous to rise,
Controller control cylinder 7 is acted, and the piston rod 71 of cylinder 7 is forward extended out, the moving knife 3 under the drive of piston rod 71 to
The suture 104 of two lower sections of eedle 102 is withstood until moving knife 3 reaches extended position, two sutures in front slide, the front end of moving knife 3
104 respectively along the curved end 32 of the front end of moving knife 3 to two side slips of moving knife 3 up to falling into hook and slot 31, and then hook and slot 31 will
Suture 104 is hooked.Cylinder 7 is acted again, and piston rod 71 makes moving knife 3 also slide backward to after-contraction, and the hook and slot 31 of moving knife 3 will be stitched
Line 104 is retracted, during retracting, and the making leaf spring 4 clamps the suture 104 on the top of moving knife 3 with moving knife 3, and moving knife 3
The suture 104 of lower section is cut by the blade of stationary knife 2.So, suture 104 is cut above sewing, while the seam above sewing
Line 104 is also jammed, and when continuing next sewing process, the lower section of sewing will not be brought into by playing the end of a thread of seam stage suture 104,
And because suture 104 is made the end of a thread of suture 104 short enough to the length between pinprick 103 above sewing by cutting, it is so comprehensive
The cooperation ball of string on the sewing caused after sewing being not in nest like, substantially increases the aesthetics of sewing.
As shown in Figure 14 and Figure 15, embodiment two:
The present embodiment is that on the basis of embodiment one, the structure between pressure foot 1 and moving knife guide 5 is changed
Enter.Specifically, the pressure foot 1 and moving knife guide in pressure foot 1 and the alternative embodiment one of moving knife guide pad 6 are used in this implementation
5.I.e. the presser foot component of embodiment two also includes two moving knife guide pads 6 extended along the longitudinal direction, and two described moving knife are led
It is arranged on pressure foot 1 and sets up separately in the left and right sides of pressure foot 1 by fastener to block 6.Two moving knife guide pads 6 are relative
Inside portion is respectively provided with inwardly protruded guide part 61, and two described moving knife guide pads 6 and pressure foot 1 constitute described guide groove
13, the stationary knife 2 is arranged on the pressure foot 1 between two described moving knife guide pads 6, two described moving knife guide pads 6
Guide part 61 constitute guide groove 13 groove top, moving knife 3 is pressed on stationary knife 2 by described guide part 61 makes moving knife 3 and the knife of stationary knife 2
The relative shearing force formed of sliding of sword can cut suture 104.So, between equally ensure that between moving knife 3 and stationary knife 2
Gap can allow suture 104 to enter and can also cut suture 104.
In two above-mentioned embodiments, each components are all detachably connected, the convenient dimensions to upper thread tangent mechanism 110
Repair and maintain.When a parts damages particularly damage for moving knife 3 and stationary knife 2, it can conveniently pull down and be individually replaced, reduce
Maintenance cost.
As described above, we are illustrated fully according to objective of the present utility model, but the utility model not limits to
In above-described embodiment and implementation.The scope that the practitioner of correlative technology field can permit in technological thought of the present utility model
It is interior to carry out different changes and implementation.
