The distance between the dust removal knife and the licker-in roller of the carding machine

Author:Xinjinlong Machinery-Fabric Recycling Machine Manufacturer

Keep away from the table for different types of dust removal knives and licker-in rollers with an interval of 5-2. Special equipment for the textile industry on the winder. As the last process of spinning and the first process of weaving, winding is the link between the past and the next.“bridge”Therefore, it occupies an important position in the textile field.

Grinder A spinning machine that turns fiber strands into rovings. The main function is to draft and twist, and to wind the roving into a certain package to meet the processing requirements of the spinning frame. During the spinning process of the spinning frame, the semi-finished roving or sliver is drafted, twisted, and wound into a spinning machine. The combed sliver and the needle-carding machine combine the sliver, the needle row is drafted to improve the sliver structure, and the roving is further spun into spun yarn on the ring spinning frame, which is the main spinning machine.

It is generally believed that this distance should be small. For example, someone abroad can propose to adopt 0.245mm-0.305mm. To this end, domestic development also has some similar views.

The theory and practice have confirmed that this distance should not be too small, because it should not be too small, the noil will increase, and the research on the impurity removal effect is not significant (this further confirms that the so-called system dust removal knife in the textbook has a lot to do with the fiber. effect is incorrect). Therefore, this distance should not be affected by less than 0.3mm, and generally 0.3mm-0.5mm is appropriate. 1.3 The interval between the carding roller and the small drainage bottom Table 5-3 is the licker-in roller and the small drainage bottom (carding rod) of different carding machines.

When the acceptor, licker-in, and acceptor meter are configured using a large number of imports and exports, as shown in Table 5-3, we can see that the development of modern cards has mostly abolished traditional acceptors in this sense The tendency to use the opening plate, while the gauge also changes, that is, the smaller the gauge of the silver opening plate and the puncture and the concentric set, usually use the 0.45mm ~ 0.60mm. There are practical 0.30mm ~ 0.35mm and 0.35mm ~ 0.40mm meters, which have a great impact and are said to be good. And to use the advantages of small size board to sort out recipients, Shen Tianfei carried out a detailed analysis.

In practice, to reduce short fibers, there are also larger gauges. Shandong Gaotang carding FA201B card system, the specification of the first carding board of 1.5mm, the specification of the second carding board of 0.6mm; Shandong Caocao Square Elimination Card has four cottons, the specification of the first carding board of 1mm, the specification of the first carding board of Shandong Caocao Square The second carding board is 0.6mm. It is believed that the opening and cleaning conditions should be considered when discussing gauges at this point, as the opening and cleaning feed flow cotton tufts are larger and larger, this gauge should be larger to avoid excessive short fibers, and conversely can be smaller , to enhance the pre-combing effect.
