Description
Technical field
The utility model belongs to technical field of textile machine, particularly relates to a kind of water jet looms shedding mechanism.
Background technology
Shedding mechanism is one of loom five great institutions, is to form the necessary important mechanism of fabric.The task of shedding mechanism is the requirement according to fabric tissue, is divided into by the warp thread penetrated on each page heald frame two-layer to form shed open up and down successively, by shed closed after weft yarn is introduced, makes to form intertexture through, weft yarn.The service behaviour of shedding mechanism directly affects the speed of a motor vehicle of loom, production efficiency, the adaptation of product and fabric quality.The shedding mechanism of existing water jet looms is that loom main shaft often returns and circles mostly, and warp thread forms a shed open, cannot meet strand at a high speed and knit the demand of opening.
As can be seen here, prior art awaits further improving.
Utility model content
The utility model is the weak point avoiding above-mentioned prior art to exist, and provide a kind of loom main shaft and often return and circle, Warp opening can reach the water jet looms shedding mechanism of twice.
The technical scheme that the utility model adopts is:
A kind of water jet looms shedding mechanism, comprise vent disk, opening connecting bar, rocking bar, shedding axle and for driving the driven unit of vent disk, the upper boom head of opening connecting bar is connected with vent disk, lower beam head is connected with one end of rocking bar, the other end of rocking bar is nested with the axle head at shedding axle, be connected for eccentric between vent disk with opening connecting bar, namely the axle center of vent disk does not overlap with the axle center of upper boom head, and the angle between opening connecting bar and rocking bar is 120 °.
The synchromesh gear that described driven unit comprises driving gear, the transition gear be meshed with driving gear and is meshed with transition gear, driving gear is nested with the axle head at loom main shaft, the number of teeth of driving gear is identical with the number of teeth of synchromesh gear, the number of teeth of transition gear is the twice of the number of teeth of driving gear, synchromesh gear is connected with vent disk bias by universal driving shaft, and namely the axle center of universal driving shaft does not overlap with the axle center of vent disk.
The axle center of described universal driving shaft and the axle center of upper boom head coincide, and the axle center of universal driving shaft also coincides with the axle center of synchromesh gear.
The length of described opening connecting bar is greater than the length of rocking bar.
The height of the axle center of the axle center of described driving gear, the axle center of transition gear, synchromesh gear and the axle center in the vertical direction of lower beam head is followed successively by from high to low: the axle center of the axle center of synchromesh gear, the axle center of transition gear, driving gear, the axle center of lower beam head.
Described shedding mechanism also comprises shedding connecting rod, fork and heald frame, and one end of shedding connecting rod is nested with on shedding axle, the other end is connected with one end of fork, and the other end of fork connects the lower edge of heald frame.
Owing to have employed technique scheme, the beneficial effect acquired by the utility model is:
1, the opening connecting bar in the utility model is connected in vent disk, and the gearratio between driving gear and synchromesh gear is 1:1, when driving gear rotates one week, drive transition gear rotates, synchromesh gear is driven to rotate again one week, make the height of vent disk point reach above once, below once, achieve driving gear and rotate the object that one week Warp opening reaches twice, meet the demand that strand knits opening.
2, the opening connecting bar in the utility model is for existing opening connecting bar, and length is longer, thickness is thicker, thus improves rigidity and the toughness of opening connecting bar, meets the demand of high speed opening.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein,
1, synchromesh gear 2, universal driving shaft 3, vent disk 4, transition gear 5, opening connecting bar 501, upper boom head 502, lower beam head 6, rocking bar 7, shedding axle 8, shedding connecting rod 9, fork 10, heald frame 11, driving gear
