Through the lifting mechanism, automatic lifting of the presser foot of the bar tacking machine can be realized; and through the presser foot structure, the phenomenon of skipping stitch in a sewing process of the bar tacking machine is prevented through the presser foot structure, thereby ensuring nice patterns of stitching.
Description
Technical field
The present invention relates to a kind of device for lifting presser foot, especially a kind of presser foot of bar tacking machine lifting device.
Background technology
Bar tacking machine is a special-purpose sewing device such as a kind of case and bag, leather, label, is mainly used in to decorate sewing.The prior art bar tacking machine drives bar tacking machine by stepper motor and moves along X-axis, Y-axis mainly by directly-drive servo motor-driven driving shaft.The bar tacking machine that has also by programming software, takes the computer control mode to finish the sewing of various styles.
The bar tacking machine of prior art lacks foot device, can occur suture bouncing pilotage phenomenon in the process of making, and can cause defectives such as the suture style is not attractive in appearance.
Summary of the invention
Bar tacking machine does not have foot device in the prior art in order to solve in the present invention, make the technological deficiency that occurs the suture bouncing pilotage in the process easily, a kind of automatic lifting device for presser foot of bar tacking machine is provided, can avoid the bouncing pilotage phenomenon in the bar tacking machine suture process on the one hand, also can realize the automatic lifting of presser foot of bar tacking machine simultaneously.
In order to achieve the above object, the technical solution adopted in the present invention is, a kind of automatic lifting device for presser foot of bar tacking machine is provided, and it comprises presser feet, hoisting mechanism; Described presser feet is connected the presser bar lower end, and described presser bar upper end is equipped with presser slide block; Described hoisting mechanism is connected with presser slide block.
Further, described hoisting mechanism comprises a driving shaft, at driving shaft one end cam is installed; A pushing ram is fixed with roller in pushing ram one side, and described roller and cam touch; A lifting arm is equipped with connecting pin on the lifting arm, lifting arm can be that rotate at the center with the connecting pin; Also comprise a connecting rod, the two ends of connecting rod connect with described pushing ram and lifting arm respectively.
Further, described pushing ram is provided with and advances the hole, and pushing ram connects by described propelling hole and connecting rod are movable; Described connecting rod one end is provided with connecting hole, and connecting rod connects by described connecting hole and lifting arm are movable.
Further, described presser bar upper end is provided with depression bar, and described depression bar passes Pressure-bar spring and is connected with presser bar.
Further, on the described depression bar pressure regulating screw is installed; Presser bar is outside equipped with the presser bar axle sleeve.
Further, described pushing ram is fixed on the noose casing by screw; Described lifting arm is fixed on the noose casing by tight loop and described connecting pin.
This device is in service, and driving shaft drives cam rotation, and when the high curved surface of the cam on the cam contacted with roller, the roller that is pressed on the cam can promote the pushing ram motion; By advancing the pore area bar that is dynamically connected, drive lifting arm by connecting rod by connecting hole by pushing ram again, make lifting arm center on connecting pin and do lifter motion up and down; Lifting arm promotes the presser slide block on the presser bar, is promoted automatically by presser slide block drive presser bar and presser feet.When the cam rotation on the driving shaft during to low curved surface, roller no longer contacts with cam curved surface, and whole hoisting mechanism is no longer stressed, and presser bar, presser feet be falling automatically under the effect of presser feet spring.
This device is when sewing, and the eedle of bar tacking machine is arranged on the presser feet lower end; Eedle is done by driving shaft driving and presser feet and is synchronized with the movement; During the eedle sewing, presser feet is done the binder action.
The present invention compared with prior art, its effect is actively and significantly.By the hoisting mechanism of the technical program, can realize the automatic lifting process of presser foot of bar tacking machine; Prevented from the bouncing pilotage phenomenon of bar tacking machine suture process to make the suture style reach related request by presser foot.
Description of drawings
Fig. 1 is the structural representation of a kind of automatic lifting device for presser foot of bar tacking machine of the present invention;
The specific embodiment
The present invention is described further below in conjunction with accompanying drawing.
The structural representation of a kind of automatic lifting device for presser foot of bar tacking machine of the present invention as shown in Figure 1, presser feet 1 are connected presser bar 2 lower ends, and presser bar 2 upper ends are equipped with presser slide block 3; Depression bar 13 passes Pressure-bar spring 14 and is connected on the presser bar 2, and the upper end of depression bar 13 is provided with pressure regulating screw 15; Outside presser bar 2, also be provided with presser bar axle sleeve 17.Presser feet 1, presser bar 2, presser slide block 3, depression bar 13, Pressure-bar spring 14, pressure regulating screw 15 mutual group become the presser foot of present embodiment.
The hoisting mechanism of present embodiment comprises: driving shaft 4 is equipped with cam 5 at driving shaft 4 one ends; Pushing ram 6 is fixed with roller 7 in a side of pushing ram 6, and roller 7 and cam 5 touch, and an end of pushing ram 6 is provided with and advances hole 11; Lifting arm 8 is equipped with connecting pin 9 in the center of lifting arm 8; Connecting rod 10, an end of connecting rod 10 is provided with connecting hole 12; One end of connecting rod 10 and propelling hole 11 active links on the pushing ram 6, the other end of connecting rod 10 flexibly connects by connecting hole 12 and lifting arm 8.Pushing ram 6 is by being fixed on by screw on the noose casing, and lifting arm 8 is fixed on the noose casing by connecting pin 9 and tight loop 16.
As shown in Figure 1, lifting arm 8 is connected with presser slide block 3, promotes presser slide block 3 by lifting arm 8, drives presser foot by presser slide block 3 and promotes automatically.
This device is in service, and driving shaft 4 drives cam 5 and rotates, and when the high curved surface of the cam on the cam 5 contacted with roller 7, the roller 7 that is pressed on the cam 5 can promote pushing ram 6 motions; Drive connecting rod 10 by pushing ram 6, drive lifting arm 8 by connecting rod 10 again, make lifting arm 8 do lifter motion up and down around connecting pin 9; Presser slide block 3 by lifting arm 8 promotes on the presser bar 2 is promoted automatically by presser slide block 3 drive presser bars 2 and presser feet 1.When the cam on the driving shaft 45 turned to low curved surface, roller 7 no longer contacted with cam 5 curved surfaces, and whole hoisting mechanism is no longer stressed, and presser bar 2, presser feet 1 be falling automatically under the effect of presser feet spring 14.Said process realizes further that along with the rotation of driving shaft 4 does not stop circulation the automatic lifting of presser foot of bar tacking machine falls after rise.
During the bar tacking machine sewing, the eedle of bar tacking machine is arranged on presser feet 1 lower end; Eedle is done by driving shaft 4 drivings and presser feet 1 and is synchronized with the movement; During the eedle sewing, presser feet 1 is done the binder action downwards, has prevented the bouncing pilotage of suture process.
