Rack Sharpness Degradation Affects Quality, Reasonable Adjustment Of Insertion Depth Of Cylinder.

< p > > a href= "http://? Www.sjfzxm.com/news/index_c.asp" > combing carding component < /a > manufacturers in order to cater for the demand of increasing the total carding point of Xilin, the cylinder density of Xilin processing is getting larger and larger, the total number of carding points is getting higher and higher, the tooth piece is getting thinner and the strength of the tooth piece is gradually decreasing. Although carding component manufacturers have made unremitting efforts in the selection of material, process optimization and surface summary processing, they still can not solve the contradiction between the high speed and high efficiency of the comber and the shortening of the sharpness degradation cycle of the Xilin rack. This is because the carding process of the high speed comber with variable speed cylinder grooming has quickened the speed of the instantaneous line (1.38~2.2 times). Take the speed of 500 tongs / mins as an example, in fact, the speed of carding is comparable to that of Yu Heng speed combing cylinder 690 times / minute ~1100 clamp times / minute speed. < /p >
< p > in embedded a href= "http:// www.sjfzxm.com/news/index_c.asp" > zigzag < /a > whole tin Lin Fasheng Xilin applique, usually the angle of tooth surface is 90 degrees, and five segmental cylinder inlaid flowers occur in the first and third groups, the tooth face angle is 90 degrees, and 4 segmental cylinder inlaid flowers occur in second groups. The 60 row magnifying glass observation shows that the first row of toothed rack of the group has been damaged. If the inlaid flower caused by the damage of Xilin rack is taken into account, other technical measures such as adjusting the insertion depth of the brush into the cylinder, increasing the brush speed and improving the cleaning time of the brush can not solve the problem of applique. Only by removing the old rack and replacing the new rack can the aim be achieved. < /p >
< p > once the "a href=" http:// "www.sjfzxm.com/news/index_c.asp" > Xilin < /a > rack degradation, or the damage caused by rack tooth damage, the impact of the cylinder inlaid on the yarn quality is greater. It shows that the percentage of droppings increases by 0.5 percentage points under the same noil spacing and cylinder grooming spacings. Production practice showed that the short staple rate of combed sliver and combed sliver increased, and the yarn quality deteriorated rapidly. < /p >
< p > when the conventional technical measures for processing Xilin are not effective, do not haste to adjust the depth of the brush palm into the cylinder. This will not only be harmful to the processing of Xilin inlaid flowers, but will also aggravate the damage of brush hair and shorten the service life of the brush. If the brush is used properly, the imported brush can be used for 6~7 years, and the domestic brush can be used for 4~5 years. The use of the brush is equivalent to increasing the depth of the brush into the cylinder by 1 millimeters. This technology can effectively and thoroughly remove the inlaid flowers in Xilin toothed sheet. Now we have all replaced the domestic brush. This is mainly due to the poor elasticity of domestic brush hair. After a period of time, the brush bristles will be dumped to one side, which will greatly reduce the cleaning efficiency of the brush. < /p >
