The cylinder of the carding machine strips the fibers from the carding rollers, passes through the flat working area of the cylinder of the carding machine, exits the flat working area from the cylinder, meets the same road, and transfers the fiber part to the doffer. 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. 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.
Since the carding quality of cotton web mainly depends on the carding quality of Xinjinlong needle surface fibers after carding in the flat working area, it is necessary to analyze the carding quality of Xinjinlong needle surface fibers after carding. Set the amount of fibers on the needle surface of Xinjinlong after one week outside the working area of the cover plate as q, after contacting with the doffer, part of the amount of fibers transferred to the doffer is g, and the remaining part (q-g) returns to Xin through the bottom of the large leak hole Golden Dragon. To measure the content of fiber q, the transfer amount of fiber g from the cylinder to the doffer can be calculated according to the following formula: When the cover flower is not included, according to the principle of input and output, the amount of the turning fiber stripped from the carding Xinjinlong silver barb should be equal to the doffer cylinder GL The amount of fibers transferred over one week to cover the surface of the needle working area should be equal to Q, ie, Qg of the amount obtained from the sum of grams of the fiber aggregate licker-in cylinder and returning fibers.
These two parts cover the working area to the fiber, which will encounter the following situations: (1) is not transferred to the cover plate, the cover plate is transferred directly from the cylinder to the plate in the working area I (2), but in the short The dwell time on the cover, the transfer cylinder and the cover return to the same cylinder in turn within the same cylinder is less, through the cylinder with the cover I(3) passed to the cover's working area, but between the cover plates Do not stay for a long time after the tin or transfer many times between the cylinder and the cover plate, the cover plate is fixed to the transfer drum for a few revolutions (even tens of rpm) is only related to the working area I (4) forest The cylinder head covers the work area and becomes the cover figure flower (the amount of this fiber is small and does not count for analysis). and the output is equal to the input. According to the principle of the cylinder head surface of the needle from the working space of the fiber around the amount Q, most fibers correspondingly consist of two parts Qg and g fiber, the fiber has two parts, the first: ( 0, (2 ) in the same cylinder type - open the fiber to the cover working area, have the cylinder child turn before (even tens of thousands of turns) inserted in the rotating working area and the cover is only in the cylinder from the fiber belt. These fibers are combed under different conditions , the quality is very different from the Qg of the amount of carded fiber to the part of the fiber, due to the working area of the post-carding cover (two, three and more times of this part of the working area of the fiber for short times cover the working area of the carded fiber, the same below), Usually carding is more complete, the tuft is relatively small, but in the process of fiber in China many times the capping carding workspace must float the neps to be pushed into the first more chance in the fiber due to the amount of fiber E in the two Between the surfaces? The needles only work after the comb board (which is called the fiber board working part to distinguish the comb fibers, the same below), especially when subjected to the first (1), (2) when the shell is combed, the whiskers are difficult to obtain sufficient decomposition .
When the fibers on the needle surface of Xinjinlong of the carding machine are transferred to the doffer, there is an opportunity cost for fiber development in the two parts of the above analysis to transfer to the doffer. One part of the fiber amount g transferred by the Xinjinlong to the doffer is one serving of rice. The staff distinguishes the fibers of the comb, part of which is the multiple use of the cover plate and the work can distinguish the fibers of the comb.
