The rotating arm constitutes a space link mechanism with a yoked connecting rod and a cross joint, and is designed so that the cross joint connected with the rotating arm can swing to and fro. The cross joint, an H-shaped link rod and a gear sector are connected in turn to form a planar four bar linkage mechanism. The gear sector swinging to and fro is joggled with a gear on a rapier driving shaft, and is connected with a rapier driving gear arranged on the rapier driving shaft, and rotates to and fro. A rapier belt having a rapier tip is arranged on the rapier driving gear. The rotating arm is connected with the yoked connecting rod, and can form a space link mechanism of different angles. The H-shaped link rod is arranged inside an arc-shaped trough on the gear sector through a gliding post on one end point, and is connected with the gear sector. The utility model has the characteristics of simple structure, compactness, usableness, reliability, reducing the number of the drive components, reducing the use cost, improving the work efficiency and high working accuracy and so on.

Background technology
Fig. 1-shown in Figure 3 is a kind of weft insertion device of prior art, specifically include the wefting insertion conjugate cam 1 of a unidirectional rotary motion, it is by roller 2 and roller 4, be converted into swinging back and forth of swing arm 3, by by swing arm 3, connecting rod 5, the four connecting rod traverse governor motions that sector gear 6 is formed are realized swinging back and forth of sector gear 6, by pinion 7 and sector gear 6, the two-stage gear enlarger that spiral bevel gear 8 and spiral bevel gear 9 are formed is realized the amplification of traverse, realizes the linear reciprocating motion of sword head sword belt by the rapier transmission mechanism of sword transmission wheel 10 and sword head 11 and sword belt 12 compositions; Loom such weft insertion device each side arranged, realize the wefting insertion function of loom.There is following several defective in the weft insertion device that said structure is formed: 1, the characteristics of motion of sword head sword belt mainly is that kinematic pair is a higher pair by cam mechanism control, and precision control difficulty is big; 2, the loom of fellow disciple's width of cloth is not that pinion 7, sector gear 6, spiral bevel gear 8 by adopting the different numbers of teeth and 9 various combination are realized, two-stage gear enlarger has been adopted in the amplification of sword head sword belt traverse, kinematic pair is more, and sword head overshoot control difficulty is big; 3, the size of weaving a width of cloth on same loom is to realize by regulating on the connecting rod 5 position of A point on linear pattern chute in the swing arm 3.The operator is when the adjustment doors width of cloth, no matter where be in, the A point slides on elongated slot, and the position of sector gear all will change, so need be through repeatedly trying to transfer the adjustment that just can finish sword head sword belt traverse; 4, be provided with 3 place's door width of cloth governing loops in the entire mechanism.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and provides a kind of simple in structure, compact, and easy to use, reliable, fault rate is low, but the many places adjusting of the door width of cloth, and the high space connecting-rod woof leading structure with adjustable door width of control accuracy.
The purpose of this utility model is finished by following technical solution, but it comprises the turning arm of a unidirectional rotary motion, this turning arm and forked type connecting rod and cross joint are formed a spatial linkage, and make continuous cross joint make reciprocally swinging, the cross joint links to each other successively with H shape connecting rod, sector gear and forms a lanar four rod mechanism, the sector gear of reciprocally swinging and the gears engaged that passes on the sword axle, link to each other with sword transmission wheel on this biography sword axle and make crankmotion, the sword belt of band sword head is installed on this sword transmission wheel.
Described turning arm links to each other with forked link, and can be formed with the spatial linkage of different angles α.
Described H shape connecting rod is placed in the arc elongated slot on the sector gear by the slide post on the end points and links to each other with sector gear.
The utility model compared with prior art has simple in structurely, compact, easy to use, and good reliability reduces drive disk assembly, reduces use cost, increase work efficiency, and the operating accuracy height, moving parts quantity is few, more adapts to characteristics such as high speed.

The specific embodiment
Be described in detail below in conjunction with 4 pairs of the utility model of accompanying drawing: shown in Figure 4, but the utility model comprises the turning arm 29 of a unidirectional rotary motion, this turning arm 29 is formed a spatial linkage with forked type connecting rod 28 and cross joint 27, and make continuous cross joint 27 make reciprocally swinging, cross joint 27 and H shape connecting rod 26, sector gear 25 links to each other successively and forms a lanar four rod mechanism, the sector gear 25 of reciprocally swinging and the gears engaged that passes on the sword axle 24, link to each other with sword transmission wheel 23 on this biography sword axle 24 and make crankmotion, the sword belt 22 of band sword head 21 is installed on this sword transmission wheel 23.
Described turning arm 29 links to each other with forked link 28, and can be formed with the spatial linkage of different angles α.
Described H shape connecting rod 26 is placed in the arc elongated slot 30 on the sector gear 25 by the slide post A on the end points and links to each other with sector gear 25.
Concrete transmission process is: the unidirectional rotary motion of turning arm 29 passes through by turning arm 29, forked type connecting rod 28, the spatial linkage that cross joint 27 is formed is converted into the reciprocally swinging of cross joint 27, again through saving 27 by cross, H shape connecting rod 26, the traverse convergent-divergent of the lanar four rod mechanism that sector gear 25 is formed, realize the reciprocally swinging of sector gear 25, through the gear enlarger of forming by the gear on sector gear 25 and the biography sword axle 24, traverse is amplified, realize the reciprocal rotation of sword transmission wheel 23, crankmotion is changed into the linear reciprocating motion of sword head 21 and sword belt 22 through sword transmission wheel, loom such weft insertion device each side arranged, realize the wefting insertion function of loom.
Motion of weft-insertion rule described in the utility model is to be realized by spatial linkage, all is that lower pair connects, and difficulty of processing is little, and precision is controlled easily.
The loom of the not fellow disciple width of cloth described in the utility model is to adopt sword transmission wheel 23, the sector gear 25 that adopts the different numbers of teeth of changing different-diameter and the collocation that passes sword axle 24 gears to realize the amplification of traverse, also can adopt the forked link 28 of different angles α to realize different motion of weft-insertion rules with turning arm 29.Variable element is many, relatively flexibly, and also simple.Whole weft insertion device of the present invention has only the one-level gear to amplify, and kinematic pair is few, and sword head overshoot is controlled easily.
The utility model is by regulating link position on the arc elongated slot 30 on H shape connecting rod 26 and the sector gear 25, being the variation that slide post A realizes sword head motion traverse in the call change of the width of cloth of same loom, the center of circle of arc elongated slot 30 overlaps with the other end of H shape connecting rod 26 on the sector gear 25 when sword head delivery position, thereby slide post A is after sliding on the arc elongated slot when having guaranteed the adjustment doors width of cloth, sector gear 25 invariant positions, the operative employee is as long as action once just can be finished the adjustment of sword head 21 sword belts 22 traverses, and is easy to operate.
The utility model can be provided with 4 place's door width of cloth governing loops in entire mechanism.
