Pile-roller up-rolling transfer type carding method and equipment

Abstract

The invention relates to a transfer-carding method for stacking roll uplink and the device. The method comprises: hair tufts is carried out a centrifugal carding and a hackling carding by a combing roller, the shag and impurity in the hair tufts are removed, fluff is up operated following the combing roller; a small cylinder transfer roll stack-up mounted upon the combing roller lifts up and transfers the fluff on the combing roller up on the small cylinder transfer roll; a doffer rally transfer roller stack-up mounted upon the small cylinder transfer roller transfers the fluff rally hanged and held on the small cylinder transfer roller up on the doffer rally transfer roller; a swinging cashmere stripping blade peels off the fluff hanged and held on the doffer rally transfer roller. The device includes a frame work, a drive institution, and the combing roller, the small cylinder transfer roller and the doffer rally transfer roller are stack-up mounted on the frame work from above to below successively. The method and device of the invention has high carding efficiency, small fibre damage, high fluff extraction rate, the floor space is little, the power consumption is low, the device can be used independently or in combination.

Description

technical field [0001] The invention relates to the carding processing technology of wool textile fibers, in particular to a carding method and equipment for animal fluff. Background technique [0002] At present, in the carding process of the wool textile industry, especially in the carding process of the animal fluff cluster, the carding equipment that uses the cashmere roller, the cashmere feeder, and the carding roller to card the fluff after carding The transfer method can be divided into: ① "Licker-in carding surface layer airflow cutting transfer method and equipment", the fluff after being carded along the high-speed rotating carding roller rotation direction with the high-speed moving carding roller produced The airflow in the boundary layer is separated and drifted off from the carding roller by the airflow cutting knife, and condenses on the device behind the carding roller that has a wind release and can collect fluff, completing a carding transfer process; ② "Li...

AI Technical Summary

Problems solved by technology

For example, "Licker-in carding--Boundary layer air flow cutting and transfer method and equipment" and "Licker-in carding-Fan suction transfer method and equipment" can complete the coarse and impurity removal process of carding well. However, when the combed fluff is transferred due to the wind force, it will generate static electricity, quickly lose the humidity in the fiber, and produce hair particles, especially when the coarse hair, impurities and fluff that have not been combed are mixed and entangled. After the wool grains are formed together, it will affect the effect of the next step of carding. At the same time, when the wool grains are continued to be carded in the next process, the wool grains must be combed again, which will cause greater fiber damage.

Another example is "the licker-in carding method and equipment". On the one hand, the fluff after being carded by the carding roller is affected by the reverse airflow generated by the lower part of the large cylinder transfer carding roller. At the same time, some useful fluff is blown down, which affects the extraction rate and causes high consumption; on the other hand, it consumes a lot of power, occupies a large area, and the equipment is relatively complicated, difficult to operate, and troublesome to maintain.

Secondly, repeated carding between the cover plate and the cylinder transfer roller will cause unnecessary fiber damage, especially when it is necessary to repeatedly card, remove roughness, and remove impurities in order to achieve the purpose of obtaining high-quality finished cashmere. The equipment is even more damaged, the extraction rate is low, the consumption is large, the power consumption is large, and the operation is difficult, so that the target of the production product cannot be achieved.
