The specific embodiment
The present invention will be further described below in conjunction with the drawings and specific embodiments.
Structure of the present invention can be referring to Fig. 1 or Fig. 2.The needle-bar 28 that needle plate 22 is housed is installed in the side plate upside of frame 2, and first rotating shaft and second rotating shaft then are fixed on the framework lateral plate 2, and initiatively shift fork 20 and driven shift fork 9 are hinged on respectively in first rotating shaft and second rotating shaft.Driving and driven shift fork is provided with partial gear, and this two incomplete gear is meshing with each other.Control lever 7 also is hinged in first rotating shaft, and is connected with active shift fork 20 by rivet 15, and both are connected as a single entity with rotating around first rotating shaft.Second rotating shaft places in the gathering sill 24 on the control lever, and gathering sill 24 is that the center with first rotating shaft is the arc groove in the center of circle.
4 sliding seat flanges 21, a pair of in twos both sides that are installed in frame 2 respectively, and in the chute 27 placed on it, can slide along this chute.Sliding seat flange 21 is used to support a power transmission shaft of batching apparatus 10 downsides.The upper end of driving and driven shift fork places the allocating slot 25 of sliding seat flange, can be along allocating slot 25 upper and lower slips.
One end of control lever 7 is provided with U-lag hole 29, opening cam 19 places in this U-lag hole 29, the other end of control lever 7 is provided with three extension spring connecting holes 30, one end and the framework lateral plate of tension rail 1 are hinged, the other end also is provided with three extension spring connecting holes 30, clasp joint control lever 7 is distinguished at the two ends of extension spring 6 and on the extension spring connecting hole 30 on the tension rail, by the extension spring connecting hole 30 on the clasp joint diverse location, adjustable extension spring 6 is to the pulling force of its formation.The tension adjustment unit of being made up of guide pad 4, adjusting nut 3, adjusting screw(rod) 5 places the upside of tension rail 1, one end of adjusting screw(rod) 5 is provided with socket, this socket is plugged on the upside of described tension rail 1, under the effect of extension spring 6, this socket is tight against on the last week of tension rail 1 side.Two guide pads 4 are fixed on the framework lateral plate along the axial space certain distance of adjusting screw(rod) 5, which is provided with pilot hole, interting in the pilot hole of this two guide pad of adjusting screw(rod), this pilot hole slides up and down relatively, and adjusting nut 3 spins on the adjusting screw(rod) 5 and places the lower end of the guide pad 4 that is positioned at upside.Same under the effect of extension spring 6, adjusting nut 3 is tight against on the lower surface that is positioned at upside guide pad 4, it can not be moved axially, thereby it is carried out axial location.The pulling force of extension spring 6 also makes U-lag hole 29 1 sides on the control lever be tight against on opening cam 19, guarantees that opening cam 19 can start to control making to control lever continuously and use when rotating.
The belt transmission unit that uses in the present embodiment is by active synchronization belt wheel 13, driven synchronous pulley 17 with synchronously with 14 transmission mechanisms of forming, and this makes transmission more accurate.Driven synchronous pulley 17 is installed on the camshaft 16, and active synchronization belt wheel 13 is installed on the output shaft of motor 12, carries out Synchronous Transmission by the tooth on it with the tooth engagement on the driving and driven synchronous pulley with 14 synchronously and is connected.
When flat braiding machine takes up one's knitting, motor 12 rotates under the control of relevant formula and by active synchronization belt wheel 13 and be with 14 driven synchronous pulley 17 is rotated synchronously, with driven synchronous pulley 17 opening cam 19 of totally one camshaft 16 rotate thereupon, opening cam 19 its radius of gyration in rotation constantly increases, control lever 7 is rotated counterclockwise, and the gathering sill 24 on the control lever 7 then produces relative slip with second rotating shaft.Rotate with active shift fork 20 companions that control lever 7 connects as one, driven shift fork 9 makes it clockwise rotate around second rotating shaft by the engagement of the partial gear on the driving and driven shift fork.During the rotation of driving and driven shift fork, slide along chute 27 laterally by the sliding seat flange 21 that drives respective side in the allocating slot 24 in their upper end, batching apparatus is opened, and sees also Fig. 2.When the maximum radius of opening cam 19 was pressed against on the U-lag of control lever, batching apparatus 10 was opened to maximum.Move on the lifting bar 11 this moment, moves to the needle plate upside until the crochet hook 23 that is installed on the lifting bar 11, plays needle knitting with knitting needle on the needle plate, and after a needle knitting finished, lifting bar 11 moved down into original position.The same reason, motor 12 rotates under the control of relative program, and control lever 7 is clockwise rotated, and the sliding seat flange 21 that then driving and driven shift fork drives respective side slides to the inside, makes batching apparatus 10 closures.When the least radius of opening cam 19 was pressed against on the U-lag of control lever, batching apparatus 10 was closed fully, and this moment, batching apparatus 10 was in the preceding desired position of work state, saw also Fig. 1.
For guarantee opening cam 19 when rotating to control lever produce effectively, continuously, transmission accurately, need to regulate the active force of 6 pairs of control levers 7 of extension spring, behind the clasp joint position of determining good extension spring 6 and control lever 7 and tension rail 1, just can regulate by the adjustment of tonicity regulon.Its adjusting nut 3 of turn, adjusting screw(rod) 5 moves axially, and then make to be tight against at the tension rail of its downside to rotate, thereby it is flexible that extension spring is produced, and control lever is produced different active forces, with balance batching apparatus suffered power when the folding.
