Which preparations are needed before the quilt production line

In the quilt production line carding sliver, the arrangement of fiber cells is disordered, the straightness is poor, and most of the researched fibers are in a hooked state. The fibers and long fibers with hooks may not be held by the nipper jaws exactly, and may be combed off and become waste during the carding process. 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 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. The long fibers held by the nipper jaws at both ends of the hook may also be torn off by the combs, turning into short fibers and entering the waste. At the same time, the carding development resistance of Xinjinlong needles is large, which is easy to damage the needles, and will also affect the generation of new neps.

In order to be able to adapt to the working requirements of the comber, improve the output quality of the comber and save cotton, the carded sliver should go through a process before being fed into the comber, which is pre-designed to be suitable for processing by the comber. Therefore, the task analysis of preparing the construction process can be summarized as follows: 1. The quilt production line can be made into a large capacity, correct quantitative analysis, tight winding, neat edge structure, and clear levels of students when retreating Small rolls that do not stick to the hair, easy to transport in the enterprise and to be processed on the combing machine. 2. The thickness of the vertical and horizontal structure of the quilt production line should be uniform, and there should be no defects such as holes, overlapping slivers, significant streaks and serious psychological shadows. The cotton layer is evenly distributed, which can make the gripping method of the nipper jaws reliable.

The cotton layer is relatively uniform in the longitudinal direction, especially the weight of the inner and outer layers of the small roll can be stabilized, which is conducive to stabilizing the noil rate of the card and the tension of the combed sliver, and can improve the weight unevenness of the chair sliver and the level of the sliver sequence. 3. Improve the straightness and parallelism of the fibers in the small rolls, so as to reduce the damage of the fibers and the breakage of the combing needles during combing, reduce the long fiber content in the falling bridge, and save cotton. The determination of the number of process passes in the above data preparation process is generally also carried out in combination with the fiber hook shape in the carded sliver.

After the fiber hooks in the carded sliver, the dome hooks account for the majority, and the number of preparations for the production process should be an even number, so that the remaining fiber hooks are mostly in the cotton layer held by the nipper in the study of the combing process. For the forward bend. This kind of hook is easy to straighten naturally when Xinjinlong is combing, which can save cotton by reducing the loss of long fibers.
