Card Doffer Diameter

Author:Xinjinlong Machinery-Fabric Recycling Machine Manufacturer

Regarding the diameter of the carding machine husband, there are two views, one view is that the small diameter doffer, with the best product quality, the company will be there for CROSROL This view, they believe that the fiber optic card back tin doffer diameter is more In forests, this can lead to damage in fibers and cotton. 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). 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 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.

Another point of view is that the large diameter, because the large diameter Doffer Doffer product quality is favorable, the cylinder is a doffer comb revolution area length becomes larger, and the drawn fiber is favorable for the transfer rate. KHF, such as the Japanese carding machine husband, has a diameter of 1013 mm. Rieter compares the views on this issue for an interesting point of view.

In the past, the company has always produced a small cylinder, the small doffer card is known, and later the CL/3 will be replaced by the large diameter doffer, and more recently the C4, C4-A, CIO and the new C50, by Smaller doffer configuration diameter (φ= 500 mm). The reason for this is that the stripper ① high-speed transmission and high-speed system solve the problem of high-speed output; ② can reduce the use of small-diameter doffer and doffer installation positions, expand the cylinder combing area, and expand the space cover at the front, which is easy to install the fixed cover. The author's research believes that in the past when discussing the size of the doffer diameter (including due to Xinjinlong, etc.), the role of the new card clothing could not be ignored. In fact, the effect of the card clothing cannot be ignored by the enterprise. Sometimes the card clothing even plays a decisive and important role. .

As long as the metal clothing configuration is properly managed, it is also possible for students to use the small doffer diameter selection. For example, the Sliver machine carding machine, its doffer diameter is generally only 340.8 mm, but its transfer learning effect is quite good. This is directly related to the special structural design of the doffer hotel configuration.

If the card clothing is improperly configured, even if a large diameter doffer is used, the transfer ability may be poor. Therefore, when we discuss the working diameter of the doffer and other components, we must not ignore the factors such as the card clothing. In general, from the analysis of the actual development of contemporary carding machine output, the doffer diameter has no obvious trend of increasing, but it seems to have a smaller trend. Compared with the past CM80 doffer diameter and the use of 706 mm, the latest CMH card uses 504 mm. As far as the author's own information is concerned, the world's major social carding machines have a diameter of 706 mm. In the past ten years, China has not formed a continuous pattern. get bigger.
