The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, it comprises warp-feeding mechanism 1, shedding mechanism 2, weft insertion device 3, beating-up mechanism 4, coiled body 5, one side of the warp let-off frame of warp-feeding mechanism 1 and the shedding frame of shedding mechanism 2 is bolted to connection, the curling frame of coiled body 5 is bolted on the opposite side of shedding frame, the wefting insertion frame of weft insertion device 3 is installed in the dead eye 8 of shedding frame both sides by the minor axis 25 that arranges on it, and beating-up mechanism 4 is connected with the wefting insertion frame.
As shown in Figure 2, be provided with successively from top to bottom on the shedding frame some shedding cylinders 16, some upper junction plates, on amplification board 15, on keevil 14, on harness cord 13, heald 12, lower harness cord 11, lower keevil 10, lower amplification board 9, some lower connecting plates 7, some return springs 6.Wherein the quantity of shedding cylinder, upper junction plate, lower connecting plate, return spring is consistent, and the hole on upper keevil and the lower keevil is the setting that is in staggered distribution, and avoids between heald and the heald, interferes between warp and the warp.The tailpiece of the piston rod of shedding cylinder is by being fixedly connected with an end of the guide plate of its perpendicular setting, and the other end of guide plate connects by the steel wire upper junction plate corresponding with it.Upper harness cord is divided into some groups harness cord in some upper junction plates place correspondence, some groups harness cord makes after by upper amplification board 15 space between harness cord and the harness cord become large, each hole of again every upper harness cord 13 being passed on the upper keevil is connected with the upper end of heald 12, the lower end of heald 12 is connected with lower harness cord 11, lower harness cord 11 is gathered into the some groups harness cord corresponding with the upper junction plate place by lower amplification board 9 after passing hole on the lower keevil 11, every group harness cord is corresponding to be connected with a lower connecting plate 7, lower end at each lower connecting plate connects return spring 6, return spring 6 upper ends are connected with the lower end of lower connecting plate 7, and the lower end is fixed on the shedding frame.Establishment rule according to multiply cloth can be provided with several groups, and tens groups, hundreds of group harness cord are realized weaving of different multiply cloths.The group number of harness cord mainly determines by the open height between warp and the warp, and the open height of warp and warp is decided by the stroke of cylinder.
When the piston rod of shedding cylinder stretches out, piston rod promotes the mutually upper motion of guide plate on it, guide plate drives corresponding upper junction plate and moves upward, the heald of corresponding upper junction plate moves upward, make between warp and the warp and form shed open, the drive lower connecting plate that moves upward of heald moves upward, thereby driving return spring moves upward, after the wefting insertion action is finished, the piston rod of shedding cylinder shrinks, upper junction plate is got back to original position, this moment return spring the effect of elastic force next time the moving lower connecting plate of bit strip get back to original position and make harness cord and heald tension.Return spring 6 can guarantee that the normal return of heald also can keep the balance of upper and lower connecting plate in the lifting process.Each shedding cylinder is by a solenoid control and then can mention row's heald according to rule, thereby warp is carried out opening.
As shown in Figure 3, be installed on wefting insertion cylinder 17 and gear 19 in the wefting insertion frame, piston rod at wefting insertion cylinder 17 is fixed with the driving tooth bar 18 that is meshed with gear 19, the wefting insertion frame be positioned at gear 19 above also be provided with chute, in chute, be provided with the driven tooth bar 20 that is meshed with gear 19, shuttle 21 is fixed on the driven tooth bar 20, when the piston rod of wefting insertion cylinder 17 drives 18 motion of driving tooth bar, driving tooth bar 18 driven gears 19 rotates, thereby drive driven tooth bar 20 reciprocating motions, because shuttle is fixed on the driven tooth bar 20, so shuttle 21 moves reciprocatingly.The shedding cylinder is mentioned row's heald so that the warp between the heald of mentioning and other heald forms opening according to rule, then the wefting insertion cylinder moving drives driven rack drives shuttle and passes from opening, the shedding cylinder continues motion and forms opening, thus the return motion of wefting insertion cylinder so that shuttle moves back and forth the realization wefting insertion.
Beating-up mechanism comprises servomotor 22, cam 23, fork 24, the output shaft of servomotor 22 is connected with cam 23, one end of fork and cam phase configuration, the other end is fixedly connected with the centre of wefting insertion frame, and servomotor 22 rotates by cam 23, fork 24 and drives weft insertion device around minor axis 25 rotation realization beating motions.
As shown in Figure 4, curling frame be provided with curling stepper motor 26, deceleration device, sprocket wheel 27, chain, on lower plate 28, described upper lower plate is looped around the periphery of chain, fabric interts in the seam of upper lower plate, start curling stepper motor 26, deceleration device drives chain by sprocket wheel and rotates, thereby drives the fabric movement in the upper lower plate.
As shown in Figure 5, be provided with successively warp beam 29, spring cord roller 30, front guide roller 31, rear guide roller 32, split rods on warp let-off frame, warp beam is provided with the friction plate of control warp tension.Warp on the warp beam 29 through spring cord roller 30, front guide roller 31, after behind the guide roller 32, sub-sand roller 33 at the harness eye that passes heald 12.
Thereby the utility model is worked out shedding cylinder that corresponding program controls shedding mechanism according to the rule that interweaves of fabric by PLC and is changed the heald of mentioning and form shed open in corresponding position according to certain sequential motion, make warp that the certain angle opening be arranged, wefting insertion air cylinder driven tooth bar behind the opening on the PLC control weft insertion device moves back and forth, driving gear bar driven gear, gear drives the motion of driven tooth bar again, thereby makes the shuttle realization wefting insertion that moves back and forth.The swing that the driven by servomotor cam of beating-up mechanism rotates, the rotation of cam drives fork, the swing of fork swings back and forth weft insertion device and beats up, and the employing of beating up is drawn a latitude and is made a call to the mode of a latitude to reduce the lax of fabric parallel, the equatorial tensile force of raising fabric.After the whole wefting insertion end of the parallel on the weft insertion device and the end of beating up, the stepper motor by coiled body turns an angle by deceleration device drive sprocket, chain again, the fabric movement that upper lower plate clamping has woven.The warp under tension was positioned at the effect that warp beam on the warp-feeding mechanism overcomes friction plate and produced rotation and the beginning warp let-off this moment, rotate and finish again to be blocked by friction plate by axle, thereby the process middle longitude that prevents from carrying out at shedding mechanism shedding is lax.
