As we all know, the carding machine has a relatively uniform development effect. The essence of the uniformity and function of the carding machine is that when the carding machine stops feeding cotton, the needle teeth release fibers. After the cotton feeding is resumed, the needle teeth absorb and utilize fibers. The cells thus alleviate the influence of the fluctuation of the feeding amount on the uneven output, which is the uniform and stable effect of the carding machine. 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.
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. 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 suction and release of fibers in Xinjinlong, flat plate and doffer part is also the result of the important role of carding and transfer. During normal production, both Xinjinlong and the cover have a certain amount of free-choice fibers stored in the enterprise. When the cotton feeding is stopped, Doffer continues to grab the fibers on the Xinjinlong, that is, the Xinjinlong and the cover release fibers, but Because the amount of fibers that can be used freely on the needle surface of Xinjinlong gradually begins to decrease, the raw sliver becomes thinner accordingly.
When the cotton supply is resumed, the fiber volume of Xinjinlong and the cover plate cannot be immediately returned to normal operation and operation, and the doffer cannot immediately request to output a sliver of normal tissue ration. It can be seen that when the fluctuation of feeding amount is relatively small and the segment is short, the carding machine has a good uniform design effect. Many social factors have a great influence on the uniform effect of the carding machine. In this section, we put forward the research and analysis of the problems as follows.
I. The uniformity of the cotton roller and the uniformity of the carding machine have a certain relationship between the longitudinal uniformity of the input coil and the output uniformity of the carding machine. The changes of the longitudinal uniformity of the carding machine and the output uniformity are random, but the change of the output uniformity of the carding machine generally changes with the change of the longitudinal uniformity of the carding machine. In addition, the carding machine itself also has a certain uniformity. Therefore, the longitudinal uniformity of the input roller is good, and the uniformity of the output sliver is good. The a186 carding machine is not equipped with an automatic adjustment system. Through the uniformity function of the carding machine, the output uniformity is standard. The difference decreases, but as the input uniformity increases, the output uniformity of the card is particularly obvious.
Secondly, the unified action of the direct injection card in the small cylinder has a certain influence on the uniform development of the carding machine. Different diameters of the Xinjinlong have a certain influence on the uniform development of the carding machine. When the diameter of the Xinjinlong can be increased, it is beneficial to the uniformity and function of the carding machine. 3. The effect of the cover pole arrangement works evenly. (1) The carding machine mainly has the effect of whether the cover plate is used for the uniform development of the carding machine. 1 Free fibers and long fibers are more on the plane than the plane, and the plane is conducive to Comb evenly. 2 In the case of no leveling, there are still free fibers in the carding machine, indicating that the cylinder has a certain uniformity and moderate effect.
③The cylinder and the cover plate have a certain effect and uniformity. The capacity of the homogeneous cylinder is generally 7/10, and it can cover 3/10 evenly. (2) The effect of a fully fixed cover on the uniform development of the carding machine The uniformity of the air flow of the spun yarn processed by the fully fixed cover card sliver is compared with the use of the movable flat card sliver to process the spun yarn. , the former has poor uniformity, while the latter has better uniformity. The reason for this is the poor ability to use full coverage of fixed carded fiber storage devices.
As a result, free fibers, the fiber absorption capacity is raised to a relatively small amount, thereby affecting the uniformity of the carding action. (3) When the number of cover plates in the work area decreases, the degree to which the cover plate can participate in a uniform development also decreases. If the number of cover plates is 30~40, the degree of participation of the cover plate through participation is 44%~48%. %.
