When the line drawing quilt increases capacity,“second-level routing”s Choice. 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). 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.
The first process is kept in a small extended area, mainly for the purpose of improving the excavation of multiple front areas, the second process is to increase the draft ratio employed for the purpose of improving the overall capability of the drawing. Most of the current selection of the first type of production process, take the period of 1.20-1.50 knitting yarn multiples to stretch the mesh fabric, when the knitting yarn is in the range of 1.02--1.20, the back roller control center consists of 5 45 to 50 Minimum yarn -37 tight after mesh drawing. The first type of technical process is superior to the second type of production process, mainly in that the unevenness of the yarn is small, and the circles 5-38 are the relationship between the drafting movement multiples of the front and rear areas and the unevenness of the yarn.
1 is that the former drafting multiple is basically unchanged (20 times), the total drafting multiple and the subsequent drafting system increase and increase (from 23.1-40.4 times); curve 2 is that the total drafting form is unchanged (30 -35 times), the front drafting theory decreases with the increase of the strip extension, the drafting process remains unchanged after curve 3 (remains 1.365 times), and the total draft increases with the increase of the front drafting mechanism. From curves 1 and 2, it can be clearly seen that the sliver unevenness is the lowest when the post draft is 1.36 times, and when it exceeds 1.48 times, the sliver unevenness gradually develops and deteriorates. This is reflected in a significant level increase in fragment unevenness at 0.8-1.5 m on both spectral circles (see circles 5-39).
The brush line 3 indicates that the draft in the rear area varies within a range (15-28 times) in the first type of process, and there is no significant correlation to the unevenness of the yarn. From this, we can see that it is appropriate to use the first type of main process for the post-drafting under different conditions of improving the front-drawing mechanism and enhancing the function of the internal control system of the manor. This is because the enterprise has small rear drafting, large drafting force, and small drafting force unevenness; at the same time, teachers can properly use the twist of roving to increase the tightness of the drafted sliver in the rear area and the front area, which is beneficial to both research. Back area control and fiber art movement, another one is beneficial for students to play the front area aprons to control the presence of fiber cell movement, so it can improve the yarn uniformity.
In addition, there is no first type of process with wider adaptability. When the raw cotton conditions and spinning numbers do not change too much, the drafting in the rear area and the spacing in the rear area generally do not need to be adjusted, which simplifies the traditional process information management and accounting work. . In addition, the rear area has a large distance, which is conducive to the development of the common application range of roller pressurization of the pressurized spun yarn drafting device whose drafting force is smaller than that of the drafting device of the quilt production line.
