Description
Technical field
The present invention relates to a kind of air-jet loom, particularly relate 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 the fabrics such as plain weave, twill, apron check according to certain rule.First the intertexture of warp thread and weft yarn needs to make warp thread form shed open by shedding motion, then by weft inserting apparatus, weft yarn is introduced shed open, finally by beating device, weft yarn is squeezed into fell, forms fabric.Formed at shedding motion in the process of shed open, warp thread constantly can be subject to cross directional stretch, and warp tension is constantly changed, and therefore, opening is comparatively large 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 large then to the intensity of loom parts and fatigue strength unfavorable, accelerate part failure, and increase difficulty of weaving.Therefore, the warp thread stretching that existing air-jet loom adopts easers to cause to relax opening 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; Need when needs change offset 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.
