(1) the design of three combing roller carding technologies:
During for many sliver feedings, when feed roller feeding speed difference is larger, each component fiber Hold time difference is larger, in single combing roller Revolving cup spinning, due to needs balance exploitation/carded fiber, and the requirement to fiber speed when transferring to comb and parallel cotton fibers prior to spinning passage, the rotating speed of single combing roller is very high, time such sliver feed quantity difference is large, the carding times that in two slivers, fiber is subject to differs greatly, and the fibre damage that carding times is many is excessive.
In order to solve combing roller rotating speed to fibre damage and the mixed uniformly problem of fibre stream, this patent adopts three combing roller forms, i.e. the 1st combing roller, the 2nd combing roller and the 3rd combing roller.The rotating speed (ω=1500-3000rpm) of the first combing roller is lower, card wire density is relatively low, card wire operating angle is relatively little, to strip, shredding, removal of impurities and point comb, the carding times that emphasis makes each sliver be subject to, in rational scope, reduces the damage of fiber; The rotating speed (ω=3000-6000rpm) of the second combing roller, to strip, divide comb drawing-off and fibre migration, card wire density is greater than the first combing roller card wire density, card wire operating angle is also relatively bigger, through the combing of the second combing roller, the machine-direction oriented of fiber is optimized, and horizontal transfer is mixed into one-step optimization; 3rd combing roller is high speed combing roller (ω=6000-12000rpm), to strip, divide comb drawing-off and fibre migration, card wire density is greater than the second combing roller card wire density, card wire operating angle is maximum, fiber not only obtains better combing and transfer through the 3rd combing roller, and running up due to the 3rd combing roller, under air-flow and centrifugal action, high separation and continuous print fibre stream is taken advantage of a situation by cotton-conveying pipe, arrangement enters revolving cup cohesion resultant yarn in an orderly manner.
Stripped by three combing rollers multistage, shredding, removal of impurities, point comb drawing-off, transfer, complete smoothly and sliver resolved into web, web resolve into bundle fiber again, bundle fiber is resolving into filamentary super draft function, improve the function in Revolving cup spinning Fen Shu district, the rotor spinning meeting the many asynchronous feedings of sliver, to a point particular/special requirement for comb, achieves flexibility, efficiently point comb function.
