Background technology
Rapier looms is to transmit warp through beam of a loom, through beat up, weft insertion device beats up wefting insertion, thereby accomplish weaving process.The fan-shaped oscillating arm that existingly beat up, weft insertion device comprises vertical setting; Rapier transmission box is housed on the wallboard, and fan-shaped oscillating arm is connected with rapier transmission box power, rapier transmission box power drive sword transmission wheel; Sword belt, sword head through being contained on the sword transmission wheel carry out wefting insertion; Because need rapier transmission box to carry out transmission of power, and rapier transmission box is easy to damage under the high-speed motion condition, service life is short.The calm time weak point that ends behind the four traditional connecting rod beating-up mechanisms; On Rapier looms, use and to increase the traverse of beating up and to satisfy requirements of weaving process; And the raising of the too big unfavorable speed of a motor vehicle of traverse of beating up; Thereby only be suitable for low speed and weave, production efficiency is low, and drawbacks such as the warp thread wearing and tearing are big, opening is unclear can occur.
The utility model content
The technical problem that the utility model will solve provide a kind ofly carry out beating up at a high speed, the Rapier looms of wefting insertion beats up, weft insertion device.
For solving the problems of the technologies described above; The Rapier looms that is provided beats up, weft insertion device comprises wallboard and be connected on the wallboard and driven by power set last power transmission shaft and lower drive shaft; Vertical front side of wallboard is hinged with and passes the sword support, is connected with the two laterally corresponding biography sword axles that are provided with on the biography sword support and is installed in the sword transmission wheel that passes on the sword axle, is connected with sword belt on the sword transmission wheel of two correspondences; The sword head is housed on the sword belt; Its design feature is: be provided with between upper and lower power transmission shaft and the biography sword support and drive the beating-up mechanism that passes the swing of sword support, wherein on the biography sword axle pinion is housed, the rear side that passes the sword support is hinged with the sector arm of horizontally set; Sector gear with pinion is housed on the sector arm, is equipped with on the last power transmission shaft and drives the vertical pendulum driving mechanism that sector arm swings up and down.
Said beating-up mechanism comprises and passes the drive link that the sword support is connected; Be equipped with on the last power transmission shaft and be positioned at the inboard inside crank of wallboard; Lower crank is housed on the lower drive shaft; Be hinged with on the last crank on connecting rod, the lower crank and be hinged with lower link, the end of upper and lower connecting rod is hinged with the both ends of middle connecting rod respectively, the approximate mid-section position of connecting rod during the end of said drive link is hinged on.
Said vertical pendulum driving mechanism comprises the outside crank that is contained on the power transmission shaft, and the bottom of wallboard is hinged with swing arm, is hinged with down the cross connecting rod of stretching on the said sector arm, and the lower extending end and the swing arm of cross connecting rod are hinged, are hinged with drive rod between outside crank and the swing arm.
Be respectively equipped with long arc-shaped holes in sector arm and the swing arm, the top of cross connecting rod and the bottom of drive rod all are connected in the long arc-shaped holes through set bolt.
The vertically preceding side lower part of wallboard is equipped with rocker, is set with sleeve on the rocker, and sleeve is connected with biography sword support through lay sword.
After adopting said structure, swing up and down, thereby drive the positive and negative rotation of sword transmission wheel, drive biography sword support through beating-up mechanism and swing, realize the wefting insertion operation through the sword belt on the sword transmission wheel, sword head along stands longitudinal through vertical pendulum drive mechanism sector arm.The utility model no longer needs rapier transmission box to carry out transmission of power, the advantage that this mechanism has that the traverse of beating up is short, the back heart relative quiescent time is long, sword head acceleration peak value is little, thereby use the utility model can adapt to higher car demand, production efficiency improves greatly.
The benefit that long arc-shaped holes is set is: can regulate the link position of cross connecting rod top and drive rod bottom, thereby adjust the rotation amplitude of sword transmission wheel, promptly increase or reduce the traverse of sword head, to be suitable for the requirement of knitting the different cloth width of cloth of system.
