Carding machine reduces impurities in cotton spinning in my country. In addition to rationally designing and selecting raw cotton, fully developing and exerting the impurity-removing effect of cleaning and carding processes and reducing the generation of neps, it should focus on improving the work of Xinjinlong and brush. Strengthen the carding of the top comb, and remove the combed noil reasonably and effectively. 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.
Carding machines are used to process cotton fibers and chemical fibers and belong to textile machinery. According to the spinning process, carding is an important process. The front process of the carding machine is the opening and cleaning machine, and the latter process is the drawing frame (carding process) or the sliver coiler (combing process).
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. At the same time, it is also necessary to continuously improve and improve the production process of small roll preparation, and strive to properly adjust the improvement and fiber straightness to improve the quality of small rolls.
1. Reasonable adjustment of the comb size and needle density of the yucca and top comb increases the carding load. Most of the small rolls are prepared using pre-cake strips.“flower by flower”phenomenon, which is the main cause of miscellaneous rises and yarn defects. In order to enhance the rigidity and strength of the needles, use 27 and 28 round or thimble flat instead of 31 or 33 thin, the quality of carding before and after the flat car is stable, and the damage of the needles is reduced. In the case of special quality requirements, the small roll is light, when the drop rate is high, increase the density of the 1-page implant needle to 28/cm, in order to enhance the comb function, the cotton drop is slightly increased, which can improve the cotton net the quality of.
figure 2. The carding machine can improve the working efficiency of the carding machine when there are many impurities and yarn defects, but the amount of cotton used is limited, which is not suitable for loosening cotton noils. Special overhauls can be organized to increase the number of comb reversals. Trim the comb in time, so that the comb is often in an efficient working state, and appropriately increase the fan speed. However, this will shorten the service life of the brushes and increase the power consumption, which can only be used as an emergency measure.
To fundamentally solve this problem, we should explore new materials and new structures for brushes. 3. Adjust the arc plate to set the delay in the arc plate, and start combing Xinjinlong can reduce the meter, and the playing needle row starts to comb, improving the action of combing the entire cylinder. Therefore, under the condition that the long fiber content of noil does not increase, the arcuate plate is positioned to be appropriately retarded by experiments.
4. Adjust the top comb to install one size. The top comb is installed with different sizes. The starting time of separation and joining is early, the amount of noil increases slightly, and the quality of the cotton web is developed and improved. 5. Strengthen the cleaning formulation and the entire velvet board to effectively perform a proper cleaning cycle on the comber, and the velvet board adopts better structure and material to reduce combed yarn defects. 6. Reasonably grasp and control the combing noil rate According to the quality management requirements of the spun cotton yarn, rationally analyze and determine the noil rate, pay attention to the noil state at any time, and reduce the table difference and eye difference.
