In order to prolong the life of carded rims, beads, and improve yarn quality and efficiency, in addition to re-election of design and manufacturing techniques, it is also necessary to use the correct options and enhance maintenance. 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. 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). There are two things to pay attention to when choosing the steel ring of the carding machine: one is that the skin has good sliding performance, neither astringent nor stagnant, and can withstand the maximum working stress; the other is that the surface can help to improve the adhesion of fibers to lubricate the film.
In addition, it is necessary to be able to select the edge height of the ring according to the different yarn counts. The selection of the bead compound, the appropriate cross-sectional shape, size, etc., is selected according to the type and quality of fibers, the amount of money yarn branching, the diameter of the ring segment edge width and the temperature and temperature conditions of the workshop, etc. Figure recipients manipulate series line interactions during operation.
The bead is easier to choose if these forces can be measured with uniform values. However, even when spinning on the same stage, the force of each bead will not be exactly the same. Coupled with other factors, this makes the traveler's choice, not so much a theoretical question, I don't know to say, it's a real one, mostly based on experience, experimentation and trying to spin the most appropriate choice under certain conditions travelers.
Through my own years of research and experiments, I have accumulated a wealth of student calculation model formulas and diagrams abroad, which can be used as a reference for our selection of steel rings and travellers. (A) Calculation of the speed of the coil of the carding machine The two speeds of the cover are the ratio of the output linear speed of the front roller to the circumference of the tube, (B) The relationship between the speed and the speed of the flower passenger card, the torsion and the diameter of the spool indicate the steel wire The relationship between loop speed, key onion, twist and spool diameter (c) The passenger speed carding machine, and the inner diameter of the constant speed ring represent the relationship between the main skin of the pin coil thread, the inner diameter of the ring and the key depression. This figure shows the situation when the tube is full and the twist is 800 twists/;meter.
For example, when the inner diameter of the ring is 50 mm and the flickering speed is 17000 rpm, the linear speed of the traveler should not be 42.8 m/s. (4) The relationship between the drawing weight and the yarn count shows the relationship between the weight of the bobbin diagram and the yarn fineness. The relationship (E) for the traveler speed of the yarn represents the relationship between the linear speed of the traveler and the yarn count.
According to this figure, it is possible to select the appropriate ring diameter and defect for a certain yarn count of the enterprise. (6) Negative effect of winding angle The tension of winding twisted yarn. Figure 3-37 shows the above formula.
The formula shows that the winding angle mu indirectly affects the twist tension, and it is necessary to determine the minimum winding angle.
