At present, the linear speed ratio between the licker-in roller and the feeding roller of the carding machine has reached about 1000, so that the feeding layer of each millimeter is extended to a fine fiber layer of one meter long. 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. 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). 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. At the same time, the fiber layer clamped by the cotton roller will be combed by the number of staggered windows (about 0.8 xlos) with a circumference of 1 meter on the surface of the licker-in roller for every 1 mm of movement during the carding process of the licker-in roller. As a result, most of the fiber bundles can be Breaks down into individual fibers or extremely light fiber bundles. However, the high-speed operation of the licker-in will inevitably lead to an increase in the noil rate. In order to maintain the stripping speed, the speed of the cylinder should be increased, thereby increasing the power consumption and vibration of the machine.
The new blade is equipped with 25.4mm lead helix 8 design licker-in roller to 25.4mm lead helix 10, and the density of carding ability is improved by measures to increase the axial sawtooth. The experimental results show that the grooved licker-in of 10,000 rpm is worse than the conventional 8 1,300 rpm licker-in, and the carding and cleaning effects are significantly improved (see Table 2-4). In the design of the carding machine, it is necessary to pay attention to the principle of using high speed, medium and low speed, and strive to achieve the goal of high quality and high output of the carding machine by continuously improving the design of the management service organization.
The licker-in material is ht20-40. There shall be no blisters within 60 mm at both ends of the outer surface. It should be treated by aging.
After treatment, it must be checked by the dynamic balance method. The structural design of the new licker-in is shown in Figure 2-15. The plugs (flanges) on the two sides of the roller body are connected with the through-through uranium of the licker-in by a tapered sleeve, which has high strength and good drama.
When the verification passes the dynamic balance, the balance is because the iron block can be displaced and fixed in the circumferential direction along the groove on the outside of the plug. After balancing, the plug is added to the socket, and the operation is simple and convenient. However, the old licker-in does not need a through shaft, and two cantilever short shafts are extended from two free fine heads, resulting in an unreasonable production structure with insufficient rigidity requirements for the operation capacity of the enterprise.
