Abstract
The utility model relates to a let-off device with constant tension. The utility model is additionally provided with a warp barn between a let-off roller of a loom and a rear beam of the loom, a warp having definite length is stored in the warp barn and the warp tension is provided through an air spring. When the working pressure of the air spring is adjusted, the warp tension can be adjusted to adapt to the weaving of integral woven fabrics having different tensile strength. The device is mainly used for integral woven fabrics having a multi-layer oblique-wave weaving structure, and overcomes the problems of tension fluctuation during weaving, uneven tension, etc.
Description
Technical field
The utility model relates to a kind of permanent tension force let-off motion, is a kind of let-off motion that can keep the warp constant tension in the loom weaving process.
Background technology
At present, under the coal mine in the ribbon conveyer core band of used conveying adhesive tape generally adopt the integral weaving thing, this braided fabric adopts integral multi-layered oblique wave braided structure.In addition, some industrial filter cloth has also adopted integral multi-layered oblique wave braided structure.Because integral multi-layered oblique wave braided fabric is used for the high workplace of requirement tensile strength more, require warp should have when weaving accordingly through line tension.
Traditional let-off motion generally is to make through the line tension maintenance constant by detect, adjust warp let-off speed through line tension.Because the tension fluctuation of heald frame in the process of opening makes that the tension force between layer and the layer is inconsistent, even also inequality along the tension force of weft direction with the warp in one deck.Inhomogeneous through line tension can not be given full play to the mechanical characteristic through wire material, makes the tensile strength of integral weaving thing descend, and causes conveyer belt sideslip in course of conveying.
Summary of the invention
The utility model provides a kind of permanent tension force let-off motion, this let-off motion can provide not with weaving process change constant in line tension.
The technical scheme that the utility model adopted is: increase a line storehouse between the back rest of warp let-off roller and loom, the warp of certain-length in store in the line storehouse is by air spring tensioning warp.Through the size of line tension, can regulate by regulating the air spring operating pressure, to adapt to the integral weaving thing of different tensile strength.
The utility model does not need to detect through line tension, has simplified let-off motion, has simplified the adjustment process through line tension.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a fundamental diagram of the present utility model.
Fig. 2 is the vertical view of an embodiment of permanent tension force let-off motion.
Among the figure: 1. warp imports end, 2. guide roller, and 3. warp let-off roller, 4. guide roller, 5. air spring, 6. idler roller, 7. guide roller, 8. guide roller, 9. brake, 10. clutch, 11. sychronisations, 12. warps are derived end.
The specific embodiment
In Fig. 1, the line storehouse is made up of guide roller (4), idler roller (6) and guide roller (7).Warp imports end (1) after guide roller (2), warp let-off roller (3) enter the line storehouse with guide roller (4) from warp, walks around idler roller (6) and derives end (12) by warp and derive through guide roller (7), guide roller (8) again.Idler roller (6) can move left and right.
In embodiment illustrated in fig. 2, air spring (5) is formed by the cylinder transformation of the way, is installed in the two ends of idler roller (6).Idler roller (6) two ends also are provided with sychronisation (11), remain parallel with guide roller (4), guide roller (7) in order to guarantee idler roller (6) in the process that moves.One end of warp let-off roller (3) is provided with brake (9), and the other end is provided with clutch (10).The rotational power of warp let-off roller (3) imports into from the end that clutch (10) is set.
Referring to Fig. 2, during work, idler roller (6) is pushed to below [in Fig. 1, idler roller (6) is pushed to right-hand] all the time under the effect of air spring (5).At this moment, brake (9) adhesive, warp let-off roller (3) is in on-position.Loom batches each time, derives end (12) pulling warp from warp, and compressed air spring (5) makes on the idler roller (6) and moves [in Fig. 1, idler roller (6) moves to left].After moving certain distance on the idler roller (6), brake (9) discharges, clutch (10) adhesive.Rotational power drives warp let-off roller (3) by clutch (10) and rotates, warp is sent into the line storehouse, idler roller (6) moves down [in Fig. 1 under the effect of air spring (5), idler roller (6) moves to right], after idler roller (6) moves down certain distance, clutch (10) discharges, brake (9) adhesive, and warp let-off roller (3) is in on-position again.
Idler roller (6) moves or moves down on no matter being, under the effect of air spring (5), warp is in tensioning state all the time.The warp constant tension.
When weaving, the opening of harness frame in aweaving machine, reduces through line tension through LSOR by opening in the closed process of trend.Idler roller (6) moves down under the effect of air spring (5), with the warp tensioning.Opening at harness frame in aweaving machine is tended to by closure in the open process, and the warp tensioning increases through line tension.When surpassing the thrust that air spring (5) can provide through line tension, warp pulling idler roller (6) compressed air spring (5), idler roller moves on (6).Under this two states, the tension force of warp is equal to the thrust of air spring (5).Keep the constant of air spring (5) thrust, can keep the warp constant tension.
Claims (4)
1, a kind of permanent tension force let-off motion, constitute by guide roller, warp let-off roller, idler roller, air spring, clutch, brake, sychronisation mechanical connection, it is characterized in that: in the line storehouse that is made of guide roller, idler roller, the axis of guide roller, idler roller is parallel to each other.
2, permanent tension force let-off motion according to claim 1, it is characterized in that: air spring is arranged on the two ends of idler roller.
3, permanent tension force let-off motion according to claim 1, it is characterized in that: the two ends of idler roller are provided with sychronisation.
4, permanent tension force let-off motion according to claim 1 is characterized in that: two ends one end of warp let-off roller is provided with brake, and the other end is provided with clutch.
