Wherein, the wallboard includes big plate and middle plate, and middle plate is located at the lower section of big plate, the company of being bolted between big plate and middle plate
Connect, middle plate is provided with several bolts hole, bolt is arranged in bolt hole, the quantity of the quantity more than bolt of bolt hole is described big
Upper beam mounting hole after being provided with least two in the horizontal direction on plate；
The tightening weft axis are alternated by slay and eccentric shaft and are formed by fixedly connecting, and the two ends top of slay is fixed with partially
Heart axle, is connected between adjacent two slay by eccentric shaft, and the center line of slay is located along the same line, and the axis of eccentric shaft is located at
On same straight line, tightening weft axis two ends are eccentric shaft, and are rotated with two wallboards be connected respectively, and slay is provided with several solid with reed
The reed supporting plate of fixed connection.
In the utility model, the surrounding of each rear upper beam mounting hole is equipped with several fixed installation holes, and the two ends of rear upper beam are equal
Flange is fixed with, flange is arranged on fixed installation hole by bolt.When after upper beam be arranged on different rear upper beam mounting holes in
When, the piece number of heald frame can be adjusted, so as to the opening mode to air-jet loom is adjusted.
The eccentric shaft is fixedly connected by bolt with slay.
The beneficial effects of the utility model：
(1) the beating axle construction that the utility model is used increased the counterweight of tightening weft axis, reduce vibration, make the air-jet loom
Smooth running simultaneously can realize high speed beating motion；Meanwhile, can move down the center of whole air-jet loom, run air-jet loom
It is more steady；
(2) by upper beam after movement, the quantity of heald frame can be adjusted, so as to change the openings of air-jet loom
Formula, increased the fertile product scope of air-jet loom institute, substantially increase the production efficiency of air-jet loom.
