The specifications of the card licker-in saw blade are shown in Figure 4-6. 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. 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). Working angle of the sawtooth of the carding machine: When the working angle of the sawtooth of the carding machine is small, the sawtooth of the carding machine has a strong ability to pierce and grasp the cotton layer, which is beneficial to the carding, but it is not easy to fall off impurities, and the licker-in cotton has been reduced. If it exceeds an hour, it will produce wicker rolls and flowers, and neps will increase.

Cotton spinning, generally use 750-80. When spinning chemical fibers, a larger working angle is used. (2) The tooth pitch p. When the tooth pitch P is small, the density of the needle teeth increases continuously, the number of teeth affected by the development of each fiber increases, and the combing effect can be strengthened.

After the tooth density is increased, the sawtooth will enhance the holding power of the fiber, which is not conducive to the transfer of the fiber to Xinjinlong and the throwing of impurities. In addition, we may increase the short pile rate. The general pitch P is 4.24-5.65mm. (3) Tooth tip thickness b: Tooth tip thickness b is divided into three types: thick type (such as 0.4mm), medium and thin type (0.2-0.3mm) and thin type (below 0.2mm). Thin teeth have good puncture technology and good combing effect. Damage and less fiber, low noil rate of card licker-in, high noil impurity content.

However, the thin teeth have low strength and are easy to be rolled and inverted. (4) Total height H of tooth tip and tooth height h: H-hour, the sawtooth increases the strength, and the fiber is easily transmitted to the cylinder, but it must be suitable for the thickness of the cotton layer. The height of the tooth tip is usually 2.7--4mmo. The total tooth height H and the height of the tooth tip can be determined according to the height of the blade base (0.5-1.6mm), usually 5.60-5.85?.

(5) Tooth tip angle y: y. Hour, sharpness is good, which is beneficial to improve puncture and combing.
