Dynamic Analysis of Cricket Roller in Carding Machine and Its Wavelength

(1) After the carding machine mainly transmits the calculation fiber of the information function, it can enter the Xinjinlong cover plate for the working area, and part of it is held by the Xinjinlong needle window, and moves with the Xinjinlong surface and movement. The structure of the double twisting unit of the double twisting machine mainly includes the spindle braking device, the spindle part of the double twisting machine, the yarn winding device, and the special device of the double twisting unit. 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. The other part is supported by the needle teeth of the cover plate and moves with the surface of the cover plate.

Because the distance between Xinjinlong and the cover plate is small, the fibers need to be transferred repeatedly between the two and data exchanged many times. Assuming that the fibers have a certain development time with the movement of the cover, and then return to the Xinjinlong, there is a transfer information function between the Xinjinlong and the cover. In order to determine our social transfer correlation function, assume that the fiber flow Xnx(t) is at the moment (t-r,) at the entrance of the Xinjinlong cover, then the following equation for studying the balance relationship of fiber cells is established. The carding machine Xinjinlong cover passes through the outlet The ratio of the function part at the entrance of the Laplace and Xinjinlong cover plates.

Because the surface speed of Xinjinlong is much larger than that of the cover, the time required for Xinjinlong to fly through the same distance is far less than the time required for the cover. If the lag influence coefficient caused by the development in the (t-r) time between the actual production unevenness r of the enterprise and the uneven production instant t is regarded as uniformity and effect, we can use the formula ( 3-13) said. The change of the output cotton web caused by any unevenness of the cotton layer in the Xinjinlong part of the carding machine can be determined by the necessary accuracy of formula (3-7).

(2) Determine the wavelength of the cotton layer of the carding machine 1. A certain amount (Xx). Suddenly the cotton is uneven. Changes in the quality of cotton webs.

In formula (3-7), insert the following conditions: T represents the response of the carding machine to changes in the cotton web, expressed as the average time (min) that the fibers can pass through the carding machine, that is, the carding machine is mainly used for carding analysis fiber time. 2. The quality change of the cotton web when the lap is fed with periodic economic fluctuations is described by the overlap in the formula (3-11), when the period is uneven, when the uneven cotton lap changes wool, the wool-like unevenness reflects The double amount of AL? sugar, although movable in the normal production process splash, 172 = 0 (significant time t) can be obtained between the amplitude of the wool (XN) agitation and the amplitude of the feeding lap (X.) he movable relationship . The maximum and a minimum of a function can be at the point where the knowledge of its derivative is equal to zero. Therefore, in order for us to determine the maximum and minimum of the function at the output of the system, take the derivation of Xn and make it equal to zero.
