(A) there is no return back and spend Feeding Feeding flowers have to spend back Suction Feeding continuous presence back the amount spent in the output loop runs cotton pipeline, each stage hopper full amount of stability, the amount of cotton fiber storage box Easy and uniform fiber density; cotton tank pressure is also more stable, no significant change in the cycle. At the same time cotton flow meter can be used to ensure that feeding cotton uniform and stable. Thus the cotton box cotton uniform and stable, the smaller the difference between Taiwan, carding machine with the number of units can be more. But back to the cotton flower to feed only a group of species, can not meet the requirements of small quantities of many varieties, and repeated cycles back the amount spent, some fibers are repeat blow, neps increased fiber strength decline, adversely on the quality of yarn.
No return Flower Feeding can be adapted to the requirements of small quantities of many varieties, can be processed 1-2 varieties, and can be adjusted to several carding units each species, did not return repeated cycles of the amount spent, it is advantageous for the yarn quality. Feeding back but no flowers do not completely full uniform at the same time each station, there are differences in degree full head, tail and intermediate machine, so the carding machine with the number of units should not be too much, generally 6-10 units appropriate. Especially when using intermittent discontinuity Feeding, even more so.
(Ii) intermittent and continuous Feeding Feeding Feeding flowers back in the absence of the way, fed cotton in three ways:
(1) pipe so that the final pressure switch a cotton picker feed roller for intermittent feed stop and turn cotton, in which case the amount has fed cotton and seamless discontinuous change, each cotton fiber tank capacity between the upper and lower fluctuation cycle, to a certain extent, caused by cyclical changes in the output of cotton box owned difference between the station, which is a cotton uneven within and between the outer-unevenness disadvantage. Particular attention should be scutcher last thugs arrive via the fan duct length of the first carding machine as short as possible to reduce the feed stop cotton latency. Pipe and pipeline there inertia cotton piping length proportional to, at the start of feeding cotton, cotton flow can not reach each station with cotton head, pipe blockage caused by the former; the latter caused by too much capacity on cotton box cotton go empty, out of uniform cotton negative.
When the comb opening machine Kam slow, reducing the number of Founding, the total amount of cotton demand is reduced, forcing Feeding rollers reduce the operating rate to balance the flow of cotton supply and demand, even worse intermittently fed cotton disadvantages. Rieter level by level potentiometer allows Feeding agencies and the number of Founding adapt improved this defect.
