Carding loss transfer rate

Author:Xinjinlong Machinery-Fabric Recycling Machine Manufacturer

As mentioned above, the carding machine Xinjinlong turns to Doffer that the amount of fibers transferred depends only on the output of the enterprise and the speed of Xinjinlong, and has nothing to do with other influencing factors. 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.

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. 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). When the output and Xinjinlong rotational speed can be determined, regardless of the transfer of Xinjinlong to the doffer and the analysis of the fiber's ability, the fiber amount g determined by the output and the rotational speed of Xinjinlong is always transferred to the doffer in one revolution of Xinjinlong. After one hour of learning ability, the amount of fiber on the needle surface of Xinjinlong before transfer will be more. Therefore, the ability of the fiber in the process of Jinlin to doffer transfer is usually expressed by the doffer transfer rate, which is expressed in two ways: the metal wire card is usually connected with the extended doffer transfer due to the continuous operation time, he Chen Peijia needle negative, but by combing y flexible Lines reduce the amount of free fiber and often do not truly reflect the ability of the cylinder man to transfer fiber selection, typically at a 72-doffer transfer rate.

Carding machine Doffer believes that the development of the transfer rate of large and small enterprises mainly depends on the type, structure and needle tooth status of Xinjinlong and Doffer card clothing, but the output of machinery and equipment, Xinjinlong speed and Xinjinlong and Doffer spacing etc. have an impact on the doffer transfer rate. There is also a large degree of influence. When the distance between Xinjinlong and Doffer is small, the fibers raised on the needle surface of Xinjinlong are easy to contact and transfer with the doffer needle teeth. At the same doffer transfer amount, the fibers on the needle surface of Xinjinlong can be less, and the doffer transfer rate is higher. High while the neps are reduced, the appearance of the cotton web is uniform. Therefore, in production and life, this distance can often be reduced as much as possible, and the general management requirement is 0.1 or 0.12 mm (4/1000 or 5/1000 inches).

The relationship between the output and Xinjinlong speed and the transfer rate of the doffer, taking the experimental research results in Table 3 as an example, when the output continues to increase, the number of free and fiber increases is the number of times these transfers increase. When the Xinjinlong rotation speed is increased, the increase in the number of free choice fibers is greater than the reduction in the risk transfer amount, which leads to a continuous increase in output and when the Xinjinlong rotation speed is increased, the doffer transfer rate needs to be increased, as shown in the table. 3-11. According to the analysis data on the carding effect of Xinjinlong and the flat plate, it can be seen that the doffer transfer rate is similar when the low yield and high speed are low yield, but there is a significant difference in the quality of cotton web carding. Low speed or low yield and high speed to achieve high yield When the quality of the cotton web is at the level of leap, the doffer transfer rate can be quite different.

Low-speed and low-yield transfer volume is small, free use of fiber volume or multiple movable flats to protect the staff from distinguishing and combing the fiber volume, increasing the doffer transfer rate will be more conducive to the quality of cotton web carding. At high speed, stable and high yield, the transfer amount is large, and the doffer transfer rate must also be at an appropriate level, otherwise the students are free to use more fibers and are not conducive to the quality of cotton web carding. But the high doffer transfer rate, not only the neps reduction is not obvious, but also because the amount of combed fibers can be distinguished from the work between the flats for many times, one inspection of the flats industry does not distinguish the combed fibers in the cotton web. The difference in the proportion of the ratio is too large, and the evaluation of the clarity of the cotton web is easy to be poor. Therefore, in addition to improving the carding quality of the fibers in the working area after the first installation of the mobile phone cover as much as possible, the Diff transfer rate must also have its own To make up for the quality and safety problems of cotton webs caused by insufficient fiber separation in the working area of ​​the cover plate project.

Generally 6~15.%. The output of the elastic metal card clothing carding machine is low, and the Xinjinlong needle surface load is high, generally 0.5---2%, to improve the doffer transfer rate, usually we can improve the quality of the cotton web carding.
