Optimizing The Density Arrangement Of Xilin Rack And Strengthening The Front Area Rack Roughing Efficiency
< p > embedded sawtooth monolithic cylinder is widely used because of its strong spinnability. In order to ensure that Xilin can maximize the carding efficiency, it is possible to reasonably deploy and appropriately increase the rack density of the pre combing area within the limited cylinder grooming interval, strengthen the combing efficiency of rack puncture, grabbing and loosening in the front area, while avoiding the overtightness of the rack in the front area, reducing the carding efficiency of the carding area, and preventing the comber from breaking the edge of the web when the a href= "http:// www.91se91.com/news/index_c.asp" > high speed < /a > condition. < /p >
< p > in this respect, some overseas a href= "http:// www.91se91.com/news/index_c.asp" > textile machinery equipment < /a > has been optimized. For example, the German schle company optimized the arrangement of pin angle and pinion density: the front 90 rack of the 90 series combing cylinder cylinder with a tooth surface angle of 90 degrees is 25 teeth / square centimeter, 62 teeth / square centimeter, and the comb point can be increased by changing the rack density in the back area. < /p >
< p > the maximum comb point of the series < a href= "http:// www.91se91.com/news/index_c.asp" > Xilin < /a > is only 30305 points, while the new two series of 96 cylinder's density is 53 teeth / square centimeter, 88 teeth / square centimeter, and the maximum carding point can reach 38980 points. At the same time, when we grasp the gradient configuration, we should appropriately increase the rack density in the back area so as to eliminate smaller neps, achieve single fiber and improve the efficiency of small neps and short linen, which is conducive to the overall improvement of yarn quality. < /p >
< p > reasonable arrangement of rack density in the front and back area of combing cylinder and proper increase of total number of cylinder carding points have great influence on improving and stabilizing yarn quality. It has also attracted the attention of technicians of spinning mills. At the same time, combing components manufacturers at home and abroad have actively developed and matched high quality combing carding elements to meet the rapid development needs of modern high efficiency comber. < /p >
Customers need to scientifically and reasonably arrange the rack density and the total grooming point of each cylinder? A spinning mill has increased the total carding point of five split cylinder of 90 degrees to five points (mainly increasing the rack density of the carding area). The quality of the cotton web is increased by 380 times per minute / minute, and then the speed is reduced to 300 times per minute / minute to get the normal output web quality, while appropriately increasing the density of the top two groups, such as increasing the density of the three groups of rack, and the total grooming point of Xilin is 47 thousand, which can meet the technological requirements of fast puncture, loosening and carding, and the yarn quality km+200% neps drop down to 25%~30%. < p > how to base < /p >
< p > but due to the larger density of Xilin rack in the middle and rear area, the blade will be too thin and too low to meet the requirements of high speed and heavy weight. If the time is not long, the first row of gear rack of the third sets of gear will break off, resulting in the occurrence of Xilin mosaic. From this point of view, the total grooming point of Xilin is not as big as possible, but the best arrangement of teeth density and the general combing point should be determined through testing according to the processing fiber condition and customer quality requirements. < /p >
