1. The configuration of raw sliver ration generally, the smaller the density of spinning yarn, the lighter the ration, and the relative lightness of ration is helpful to the improvement of carding cotton and yarn-forming cotton miscellaneous. 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.
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). But the weight is too light, the cotton net is easy to float, and it is easy to increase the broken ends and make the evenness uneven. The ration of raw sliver is generally between 20-25g/5m.
2. The main output of the carding machine and the setting of the sliver speed are different in the working diameter of the modern carding machine. After adopting the new stripping mechanism and tufting device, the tension and draft of the cotton web are quite different, and the production level of the cotton web cannot be expressed by the Doffer speed. Card output depends on card type, processing and spinning raw materials, yarn quality requirements and sliver quantity.
The maximum output of the product specification is the design output, the actual output is 50%-70%, and the sliver output is proportional to the sliver speed. As shown in Figure 3, the cylinder diameter and Lin anchor speed configuration Xinjinlong diameter are the most important design parameters of the carding machine. The geometric structure combination of Xinjinlong, licker-in, and doffer position directly affects the size and size of the carding area by affecting the angle and arc length of the work area for students' carding research, turning the flat plate, fixing a flat plate, and cleaning the cotton net. combing degree.
Xinjinlong speed can directly affect the analysis of carding degree and centrifugal force of carded fibers, and plays a very key role in the transfer of fibers and the development of impurities that cannot be excluded. With a diameter of 1284 mm, the traditional card bare cylindrical shape is repeated several times, and the current trend of diameters is diverse and not consistent. Reduce the diameter of Xinjinlong, keep the same linear speed as the large diameter, and keep the carding degree of fiber per unit working time unchanged.
The high-speed rotation of the small diameter can increase the centrifugal force of the students' carding medium, which is beneficial to improve the transfer of fibers and the removal of impurities. The reduction of the diameter can also reduce the change of the thermal expansion rate of these metals. The variation can be reduced, the length of the fuselage can be shortened, and the space occupied by the enterprise can be reduced, but for the environment where the diameter gradually decreases, the speed of Xinjinlong will increase, and the probability of mechanical structure vibration will increase. Dynamic and static combined balance, etc., will have higher requirements. Therefore, our Xinjinlongs with different diameters have their own advantages and disadvantages. The Chinese card Xinjinlong used to have a diameter of 686 mm (A187), but it is now basically uniform.
12884, the configuration of the speed of the licker The licker-in is the first carding element of the carding machine. Lick-in carding is the only card-holding process in Xinjinlong carding area. The speed of the licker-in will affect the performance of the front part, it belongs to the belly cotton, cleaning, and fiber damage has a lot to do.
Too high a licker-in speed can easily damage the fibers. Fiber damage and fiber properties, length during carding, thickness of baby cotton coated serrations (pin teeth) relative specifications. Modern triple licker-in card, first with thin-purpose through-tooth, low-speed needle roller carding, and then gradually accelerated, serrated teeth and coarse roller carding are achieved to reduce fiber damage and not weaken fiber carding and transmission of results.
The first line speed is higher than the line speed below the conventional single licker-in. Practice has proved that clamping and carding fiber damage is the easiest, therefore, low speed should be controlled. The configuration management of licker-in speed is also restricted by Xinjinlong speed.
The ratio of Xinjinlong and the surface treatment speed of the licker-in must ensure the good development and transfer of the fibers on the licker-in, and the neps and short staples will not increase due to the repeated carding problems of the students.
