The air jet loom adopts new type electronic control system.
New designed frame structure.
New designed low vibration beating balance system.
New designed air bag structure of main nozzle and stretch nozzle.
New designed double back rest let-off structure.
Higher efficiency weft insertion system.
The air jet weaving machine adopts super power-saving electromagnetic valves and nozzles.
Powerful weaving expert system.
The air jet weaving machine adopts high rigid frame structure, big diameter beam gear and positive let-off driving beam with bath lubrication, which make loom suit for the high density fabric at high speed. Both side cam box wall board and frame structure have been optimized, it well improved resistance to vibration and dependability, and well ensures the loom work in high speed; wider width and low noise.
The beating axis adopted new designed beating dynamic balance system, it improved the beating-up force of the loom, and the vibration of the whole machine is reduced, it is more effectively ensured to weave the high-count and highdensity fabric.
A 4-link beating motion that works excellently at ultra-high speed and a short connecting rod are used for standard looms. A 6-link beating motion with more time allowance for filling insertion is used for wider looms, thus achieving more stable filling insetion.
The RIFA weaving machine features a user-friendly graphical interface with clear icons, enabling simple operation and easy modification of pre-saved fabric weaving parameters. Its advanced automatic algorithm calculates air consumption in real time, enhancing factory management digitization. Furthermore, the system allows for online adjustments of weft insertion angle and air pressure, effectively minimizing air consumption.
Warp tension can be adjusted automatically when loom is started, this can avoid tension change during Ioom stops and further avoid stop marks.
A new type electromagnetic valve manifold is with high sensitivity, this can ensure a stable air pressure during accurate jetting and stable weft insertion at high speed. The integration of stay pin and sub-air bag connects new type electromagnetic valve, this can shorten the distance from valve to nozzle, and improve machine speed and efficiency.
