Cot-wrapped rollers and rollers of carding machine are a serious psychological obstacle in the carding process. The consequence is a sharp increase in end breaks, a reduction in the production management efficiency of the machine, an increase in yarn defects, and a decrease in the quality of enterprise products and services. Grinder A spinning machine that turns fiber strands into rovings. The main function is to draft and twist, and to wind the roving into a certain package to meet the processing requirements of the spinning frame.
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). The main reasons for the phenomenon of wrapping rollers and wrapping rollers in the production of carding machines are as follows.
Static electricity.1. The static electricity generated during the processing of chemical fiber and chemical fiber semi-finished products is more than that of pure cotton, which is the main reason for rollers and glue. The surface friction between the chemical fiber and the rubber roller or Laura generates static electricity. Due to the poor electrical conductivity of chemical fibers, the electrostatic charge is not easy to deviate, so the fibers are wrapped on the surface of the rubber roller or roller.
figure 2. The cotton sliver is waxed more, the cotton sliver wraps the rubber roller, and the roller is mainly for the waxing effect of the cotton sliver. The cotton thread is bonded inside the cotton thread, especially the wax of the cotton thread melts at high temperature, which is easy to cause winding rollers.
The faster the machine speed of machine 3, the greater the relative movement speed of the fibers when drawn, the more static electricity is generated. Also, when the plastic spool is heated too fast, it can cause the cotton wax to melt, so faster card rollers or drums tend to get tangled. Reasons for easy winding around high speed machines and rolls or plastic reels.
4. Wet temperature When the temperature of processing raw cotton is 22-24℃, the production enterprise is normal. When the temperature can exceed 32℃, the cotton wax melts and the oily chemical fiber becomes sticky, which is easy to wrap around the roller or the rubber roller. The relative humidity of the drawing process is generally controlled at around 60%-65%. When the processing method is used to synthesize research fibers, if the relative humidity is lower than 55%, the rollers or rubber rollers will be wrapped around due to serious static electricity. 5. In raw and matured semi-finished products, compared with the second-track drawing frame, the second-track drawing frame has more entanglement.
Therefore, the more cooked the sliver, the better the fiber straightness, and the easier it is to spread, so the phenomenon of winding rollers or glue sticks is more. In view of the above analysis reasons, we need to take some corresponding measures to solve them.
