In order to simplify the problem when the quilt is subjected to the action of the production line back to the cylindrical fiber bundle and the airflow, imagine that if it is a two-dimensional model as shown in Figure 3-26, the Lang pair contains the cylindrical fiber bundle axis, The rectangle in the Chinese diameter direction and the fibers in the section S are analyzed and investigated. 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. 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). 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. Secondly, it is assumed that the following settings are necessary for the felt production line model: Assumption 1 (fiber head spacing): Let the whiskers be random whiskers, and the fiber head spacing along the uranium direction is an exponentially dominant distribution. Assumption 2 (fiber length): (2) Extend the quilt production line in two- or three-dimensional space.
In the case of (1), the feed sliver (sliver or roving) is generally fed into the highly inert sliver through roller drafting, but during the roller drafting process, due to: 1. The feed sliver is in a concentrated state, and the fibers are The airflow is uneven; 2 When a given draft ratio exceeds the rainfall, there will be fiber passages around the roller and problems such as draft sentences. Therefore, it is better to use mechanical or aerodynamic methods, such as (2) loosening the neckline in the space before or at the same time as the airflow pulls to make the airflow even. Therefore, the most suitable separation method, one is to expand through the diffused airflow that the fibers are stretched, and the other is to attract the other is to comb through the thick whiskers to make the neckband thinner, repeat through the space expansion, and be affected by the effect of air relaxation.
The former is carried out by the roller, the latter is carried out by the diffuser through the spatial diffusion of the carding roller and the fibers, and the latter is carried out by the superimposed flow, and the following two methods are described.
