Description

Alternating expression shuttle wheel construction

Technical field

the utility model relates to a kind of circular weaving machine shuttle minor structure, belongs to plastics package machinery field.

Background technology

Circular loom refers to utilize circuit orbit in the warp opening friendship, carry out throwing in the weaving machinery of parallel.

Existing equipment structure as shown in Figure 1, containing motor pulley 1, belt 2, big belt pulley 3, main shaft 4, cam 5, clip wheel 6, lever 7, comprehensive band deflector roll 8, comprehensive band 9, heald 10, nutted rod 11, shuttle 12, spindle 13, circuit orbit 14, shuttle pushing wheel 15, organizine 16, determines longitude circle 17, braiding cylinder cloth 18.

Operation principle is as follows, power is reached main shaft 4 through motor pulley 1, belt 2, big belt pulley 3 by motor, again by the cam 5 be fixed on main shaft 4 by being fixed on clip wheel 6 activation lever 7 on lever 7 around fixing point reciprocally swinging, finally driven by lever 7 end and combine band 9, heald 10 pumps together.

Be through organizine 16 on heald 10 under the driving of comprehensive band 9, inside and outside layer completes to open ships dynamic, and the organizine 16 that nutted rod 11 can split friendship provides suitable tension force to open friendship with what ensure organizine 16.The spindle 13 that shuttle 12 is installed, circuit orbit 14 has been driven by the shuttle pushing wheel 15 be fixed on main shaft 4 motion of throwing in weft yarn.Determining longitude circle 17 is folding footpath size for fixing braiding cylinder cloth 18.

At present, though the plastic flat fiber used in plastic flat yarn circular loom due to the total quality of wire drawing machine have larger difference cause flat filament TENSILE STRENGTH and percentage elongation index qualified, but above index has larger difference in focal length and individual filament cross section width dimensions, and because organizine will under certain tension force in circular knitting machines process, should complete out that to hand over be that the shuttle of high-speed cruising provides necessary and opens Crosslinking Mechanisms, bear the shuttle wheel on the shuttle throwing in tram again and running the impact spreading to organizine on guide rail relative to the ledge of shuttle outer.Because the double action of organizine material to the higher impact of frequency and spreading is comparatively responsive, so can on being woven with larger impact.As can be seen from Fig. 2 and Fig. 3, front and back shuttle wheel 19,20 when shuttle 12 runs in guide rail on shuttle 12 operates on the same Radius of same guide rail, when organizine 16 slowly moves to center with the speed (being determined by the picking density of tram) of setting, the front and back shuttle on shuttle 12 take turns 19,20 successively spreading on organizine 16.The spreading zone length formed thus is that the wheel of front and back shuttles wheel 19,20 adds the slow moving distance value of organizine 16 within front and back shuttle wheel 19,20 spacing running time along width dimensions.Before and after shuttle wheel 19,20 due to overall structure reason, the large percentage that wheel is shared in wider relative spreading region, not only because the moving distance value of organizine 16 but also little, the region 21 that thus form the repetition spreading of shuttle wheel in spreading region is more, as shown in Figure 4.

As can be seen from above-mentioned analysis, how to allow front and back shuttle take turns 19, the 20 repeated impacts spreading regions 21 of minimizing to organizine 16, to reduce the damage to organizine, improving weave cotton cloth quality and labor productivity, is that current circular weaving machine shuttle wheel holds problem to be solved.

Summary of the invention

The purpose of this utility model will overcome above-mentioned the deficiencies in the prior art exactly, a kind of shuttle wheel construction of improvement is provided----alternating expression shuttle wheel construction, take turns because of the repeated impacts spreading to organizine with the shuttle overcome on the shuttle of high speed picking circular motion, and to organizine produce local failure cause split silk and disconnection problem, effective minimizing spreading region, thus improve weave cotton cloth quality and labor productivity.

The technical scheme adopted for realizing above-mentioned purpose of the present utility model is: a kind of alternating expression shuttle wheel construction, the front shuttle wheel comprising shuttle and be arranged on shuttle and rear shuttle wheel, its design feature is: front shuttle wheel is taken turns with rear shuttle and distributed in alternating expression, namely the radius of the running rail that front shuttle wheel is corresponding is different from the radius that corresponding running rail taken turns by rear shuttle, and the running rail radius of rear shuttle wheel is greater than the running rail radius of front shuttle wheel.

The utility model is due to the front and back shuttle wheel employing alternating expression distribution of shuttle, the radius of the running rail that front shuttle wheel is corresponding is different from the radius that corresponding running rail taken turns by rear shuttle, namely the shuttle wheel before and after shuttle, symmetry direction installed operates on the track of different radii, the organizine region effectively can reducing the spreading of front shuttle wheel like this allows rear shuttle take turns spreading again, decrease the region area of repetition spreading to greatest extent, thus the injury decreased organizine, improve weave cotton cloth quality and labor productivity.

Detailed description of the invention

For further illustrating the utility model, below in conjunction with accompanying drawing and the concrete example implemented, further detailed description is done to the utility model.

As can be seen from Fig. 5, Fig. 6, Fig. 8, the front shuttle wheel 19 of shuttle 12 and rear shuttle wheel 20 distribution in alternating expression, namely to take turns 20 corresponding running rail radiuses different for the front shuttle running rail radius of taking turns 19 correspondences and rear shuttle, the running rail radius of rear shuttle wheel 20 is greater than the running rail radius of front shuttle wheel 19, and rear shuttle wheel 20 and front shuttle take turns 19 through upwards relative misalignment distance A.Because front shuttle takes turns 19 operating radius and rear shuttle, to take turns 20 operating radius different, thus decrease the organizine region that front shuttle takes turns 19 spreadings and allow rear shuttle take turns the area of 20 spreadings again.As can be seen from Figure 7, spreading region 22 is repeated obviously less.Our experiments show that, the equipment after improvement, operating efficiency has greatly improved than before.
