Description
Technical field
The present invention relates to a kind of air-jet loom, relate in particular to a kind of easers of air-jet loom.
Background technology
In air-jet loom running, warp thread and weft yarn can be intertwined to form according to certain rule the fabrics such as plain weave, twill, apron check.First interweaving of warp thread and weft yarn need to make warp thread form shed open by shedding motion, then by weft inserting apparatus, weft yarn is introduced to shed open, finally by beating device, weft yarn squeezed into fell, forms fabric.At shedding motion, form in the process of shed open, warp thread can constantly be subject to cross directional stretch, and warp tension is constantly changed, and therefore, opening is larger on warp thread distortion, warp tension impact, particularly the production of highly dense, heavily fabric.Warp thread deflection will certainly increase end breakage rate greatly, reduces weaving efficiency; Average tension on warp is large unfavorable to the intensity of loom parts and fatigue strength, accelerates part failure, and increases difficulty of weaving.Therefore, existing air-jet loom adopts easers to relax the warp thread stretching that opening causes mostly, to keep the stationarity of tension force.
At present, the offset of most easers only has three models, and the warp tension size that can change is very fixing, cannot accomplish the accurate control to tension force; When needs change offset, need to change eccentric bushing, work very loaded down with trivial details, for different fabrics, also need to change different eccentric bushings, greatly reduce operating efficiency.
As can be seen here, prior art awaits further improving.
