The entire front and rear cover plate, the back cover is fixed, the modular card cover is fixed for daily installation Lidulin and ancillary equipment, the spread is fixed to improve the effect of carding impurities, and the cardboard Xinjinlongjia rapid progress is added to remove cardboard scraps, small The degree of finishing after the dust is mixed, the function of short fibers, etc. 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. The structure of the double twisting unit of the double twisting machine mainly includes the spindle braking device, the spindle part of the double twisting machine, the yarn winding device, and the special device of the double twisting unit. One vector is to develop the self-cleaning function of the fixed cover plate of the progress cabinet and ensure the stability of the carding quality. The general trend is to add a dust-removing knife and a negative pressure suction pipe cotton net cleaning energy system.
The German DK903 high-yield carding machine has 6 fixed covers at the front and the rear, and is equipped with a dust removal knife and a negative pressure suction pipe. The Swiss C60 high-yield carding machine is equipped with 9 fixed movable covers, dust removal knives and negative pressure suction pipes. After installing some fixed and cover plates on the high-yield carding machine, the quilt production line carding machine forms an information-based carding and impurity removal system consisting of fixed installation cover plates, negative pressure suction, control panels, etc. The construction of the cover plate structure system has the following three effects: (1) The average rate of eliminating heteroknots in the carding machine ratio is improved, so that the yarn breakage rate.
(2) The rear fixed cover plate has the effect of pre-carding, and the front fixed cover plate has the effect of sorting us and directional sorting of Chinese fibers. (3) The cotton net cleaning system is equipped with a fixed cover system, in which the negative pressure air intake can absorb the impurities, short lint and fine dust on the dust removal knife in time. Suction and fix the cover plate, and can also adjust the air flow in the carding area of Xinjinlong and the cover plate, so that the fibers can be well retained on the Xinjinlong needle surface during high-speed reversal, so that the fibers can be easily transported to the Dough, which is beneficial to the Dough network. , to improve the dispersion of fiber length in the sliver.
With the development of finishing skills, the number of fixed flats in high-yield cards is gradually increasing, as the number of rotating flats is decreasing. Compared to a high-production carding machine with 40 reverse operation area covers (without fixed front and rear covers), 14 rear fixed covers, 24 reverse operation area covers, and 4 front fixed covers, the fixed covers are more efficient. Many high-yield cards have 31% less neps than ordinary cards, and the spun yarn cv is worth improving. Comparison description: It is very beneficial to increase the number of fixed cover plates, reduce the number of reverse operation cover plates to remove impurities, and improve the quality of the strip.
It is estimated that with the development of high-yield card skills, there may be a new high-yield card without the reverse flat bar and all fixed flats. Keywords on this site: carding machine, quilt production line, blowing and carding box.
