Background technology
Sizing is one of important procedure of preparing before textile industry is knitted.Because obvolvent is not strong between the fiber of raw yarn (FDY), surface hairiness is more, is difficult to directly weave.For improving the weavability of warp thread on loom, so that effects such as warp thread can bear the stop over sheet at loom, combines, the repeated friction between reed and the warp thread etc., stretching, bending, and unlikely fluffing even broken end, just must apply slurry to improve the technical process of its weavability at warp thread, this process is exactly sizing.Sizing is a complexity and elaboration, in order to guarantee the quality of starching, requires in sizing process, and it is even and constant that the tension force of warp thread should keep.In order better tension force to be controlled, usually can be divided into several districts to the tension force of sizing process (as: unwinding tension, feeding tension force, wet district tension force, dried district tension force, winding tension) control, each district's separate transmission control, wherein wet district is the most responsive most important zone in the starching overall process.
The wet district course of work of existing Sizing machines is mainly: yarn is after drawing the yarn roller and going into stock tank, along the yarn direct of travel, successively through the submergence roller, sizing roller, squeezing roller, then through drying room, the drying cylinder drying, arrive the slurry axle again, wherein, before drawing the yarn roller tension force measuring roll is set, between drying cylinder and the slurry axle tension force measuring roll and measuring roller are set, testing result by this two place, wet and distinguish the assessment of percentage elongation, therefore, the percentage elongation control of wet district is main recently to be finished by flexible between the default main motor of touch-screen and the sizing roller motor, then controls linear velocity separately by main motor and sizing roller motor respectively according to known (or calculating) velocity amplitude in the running.
If L
1The length of yarn in wet district, L are left in expression
2Expression enters the length of yarn in wet district, and the percentage elongation in so wet district just equals (L
1-L
2)/L
2* 100%.If the default roller linear velocity V that tows
1, wet district percentage elongation is d, so sizing roller linear velocity V
2Just equal V
1/ (1+d).
Yet, because the interference of wet each parts of district and factor, wet district tension force presents unsettled phenomenon, influence the effect of starching, and the length that causes starching axle is inconsistent, desirable situation has just been considered in above-mentioned design, in fact, owing to be subjected to other parts (as squeezing roller, drying room etc.) influence, the tension force at yarn place can not be reacted by percentage elongation fully, thereby inflexible linear velocity of forcing to set sizing roller according to computing formula will exert an adverse impact to percentage elongation or the starch finishing effect of reality, so and cause waste during axle, be unfavorable for running smooth of sizing operation.
Have based on this, make the utility model.
