Carding machine weaving enterprises in some countries with special functional fabric materials, such as metal used in Chinese construction, pass through the wire mesh, and use the student's active feeding mechanism, relying on a friction method to simply drag the warp. Menstrual volume does not self-regulate. 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.
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. This kind of other people's money and goods has a very low weft density and a large amount of let-off each time.
When there is a slight difference between the let-off amount and the weaving amount, some passive take-up control mechanisms are used to balance the warp tension in the process. A little understanding of the difference has little effect on the quality management of weaving and mail removal. The number also adopts the weaving quilt type let-off mechanism, but in the main mechanism of the carding machine, there is a nerve tension roller, and the amount of warp is too much. After accumulating to a certain degree of development, the tension roller will go down, cut off the dynamic source of the power transmission technology system, and stop the let-off. Later, due to the gradual tension of the warp direction, the tension roller rises, and a transmission design system is connected to resume the let-off. Because we do not need to adjust the production device by ourselves, it is relatively simple for us to actively invite and comb, but most of the warp packages of the let-off mechanism are made into the form of woven shafts, but in traditional weaving, the warp count is very low and the weft density is high When some thin research fabrics, such as cord fabric, heavy canvas, and thick-diameter metal-bonded wire mesh, still need to be packaged with woven shafts, they will be frequently used on the machine because the working time cannot be too short.
Linked to the society this kind of learning situation is cool, the use of Hengzi roll: chewing? Comparing skills is appropriate. As shown in Figure 10-5, these raised bobbins 1' are on the bobbin frame, and the friction drum 6 with active AC drive will find the yarn into pieces from each bobbin. In the circle 2 is the guide box, 3, 4 It is a guide roller, 6 is a pressing roller, 7 is a tension ear, and 8 is a post-mining. The cheongziwei occupies a large area, but you can choose to omit the work of 'Tingjing, piercing (pinning), and upper machine sentence'* .When the number of warp yarns is large and the cloth flags are narrow, the herringbone bobbin can be used, such as the 13 canvas loom for the shop cloth loom. In-line bobbins in a parallel configuration of the main input and output, such as for heavy machinery metal and wire mesh looms.
