Metal pin card according to the tooth cloth and the code element name shown in Figure 2-20. 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. 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 working angle a sets the resultant force (carding force, air flow resistance, elastic force between fibers, etc.) on the sawtooth tip fibers during movement as F (Fig. 2-21), which is between the centerline of the tooth tip speed development direction and the The included angle is , then the subsidence component force FT and the increase of the positive pressure when the working angle of the tooth tip is a are respectively, it can be seen from the formula that in . At the same time, the larger the a value of the working angle, the smaller the sinking score.

When the working angle is smaller, the sinking force becomes larger. When the friction coefficient between the tooth surface and the tooth surface is the friction angle between the tooth surface and the tooth surface, in the case of satisfying the lower formula, the fibers on the tooth surface will not sink to the tooth root along the working surface, and also Will not float off the top of the tooth along the working surface. In other words, the above research inequality can not only effectively ensure that these fibers are held or combed by the tooth surface of the second carding needle at the street tip, but also reduce the load on the tooth surface by improving the transfer learning ability of enterprises.

Carding machine Xinjinlong sawtooth or working angle at value should be too large, so that the fiber is not easy to choose to sink into the window root, so as to increase the chance of being combed and mixed by the equipment holding method at the tooth tip, and at the same time, it can enhance the transfer of enterprises and the stability of fiber. ability. However, if the at value is too large, the carding management efficiency level of the gripping part will be reduced, resulting in an increase in the ugliness of a cover plate and a weakening of the ability of Xinjinlong to pick up different fibers from the licker-in. According to the fine shape of the spun fiber, the diameter of Xinjinlong and the rotation speed, the working angle of the tooth tip of Xinjinlong is selected within the range of 60-80.

With the high speed of the carding machine to achieve high output, the at value should generally be developed to a smaller value for students. According to different classification objects, when selecting the working angle of the Rocky principle, high fiber grams (plush fibers) and long fiber elbows, large fiber lengths, more opportunities for clamping through the sawtooth, in order to ensure a certain degree of peelability, Larger values ​​are preferred. When in the large cylinder (1282mm) the traditional straight tooth saw packet window, at 75-80=.

If A.80, the combing effect will be weakened. When spinning and coating a large cylinder of yarn in the lower center, the linear zigzag window, at 70-75 =, allows for adequate grip and has some ability to release. According to the different sizes of Xinjinlong diameter and Xinjinlong speed, the principle of selecting the working angle at is that the Daxinjinlong sawtooth used for high-speed development and high production or the working angle at should take the smaller value (70-75), so as to reduce the centrifugal force of the enterprise. In a large situation, the holding force of the sawtooth is maintained, a reasonable transfer rate is maintained, and a better quality of cotton web is achieved. Under the same working and learning speed on the surface of the anchor forest, the working angle of the sawtooth of the small pavilion should be selected to have a higher working angle. Small value (60~65).

Because under the same surface treatment work analysis speed, the high speed of Xiaoxin Jinlong will generate greater centrifugal force on the fiber structure. effect, deteriorating the quality of the cotton web. Card Doffer serrated corners. , a small value should be selected to ensure sufficient grasping and concentrating fiber ability, but the grasping ability is too small, and the grasping ability is too strong, the fibers will not be transferred prematurely, which will affect the carding quality.
