Production line traction device quilt

Author:Xinjinlong Machinery-Fabric Recycling Machine Manufacturer

The quilt production line adopts the spun spun spun yarn (towel, fine yarn), and the total draft is 100--250 times the drafting system device, which is called super-large drafting. 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.

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).

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 use of a super-large drafting spinning frame can save the roving process, improve the labor and social productivity of the spinning department, save the space occupied by the factory building of the enterprise, reduce the production equipment and investment management costs, and have a better economic activity effect. One of the research directions for the development of the device.

The technological characteristics of the super-large drafting device of the quilt production line (1) The reasonable combination of the drawing area of ​​the quilt production line increases the total drawing ratio of the device, not more than two: the increase in the drafting area (1); (2) Increases the ability to draft each draft zone. The former not only increases the organization and troublesome operation, but also reduces the economic effect, as long as the latter can give full play to the ability of each stretch belt draft, and rationally utilize various combinations and drafting areas, it is not difficult to get a good large pressure. It is a simple mechanism and easy to operate. Mature experience Conventional drafting mechanism, the upward front area curve double apron drafting ratio to 15-25 times, in the capacity as long as the back reaches the draft 5-10 times, to meet the needs of large spinning of sliver linear four rollers Yarn drafting device.

In order to improve their ability to draw rational use of each drawing area combination, it has become the most important topic of large drawing equipment. The four-roller direct-spinning roller pulls up the large drafting device. The front area adopts double apron curve drafting, and some simple roller drafting areas are used in the middle and rear areas. The pressure working mechanism can use a spring cradle pressure processing device. Type automatic data import type upper opening is the synthesizer.

Practical research points out that it is necessary to carry out scientific and reasonable drafting and divide oneself, correctly and effectively use the drafting in the teaching area, fully develop and play the role of the collector in each area of ​​the city, solve the sliver feeding method, and strengthen the control of fiber art movement in each drafting area. Its yarn quality is the best; it can achieve the expected learning effect of the enterprise. (B) In the drawing area of ​​the blanket production line, the sliver of the quilt production line becomes looser after one drafting in the rear area, and the fibers and fiber cells develop relative horizontal displacement at the loosest part of the sliver. Feeding the draft in the middle area, the sliver will become straight and spread. If the 5 sliver is drawn through the front area, it will definitely affect the unevenness of the cultural output sliver. In order to solve the above analysis problems of the enterprise, some outside the circle have super-large drafting devices.

After the yarn is drawn twice, add the intermediate transition draft! Cell, its stretching 1E~ multiple is in the range of 1.07-1.4, so that the yarn tension pulls rain‘Tension, increasing the tightness between fibers. However, such an approach inevitably creates institutional complexity. If the transition drafting zone is replaced by the central collector, not only the mechanism is simple, but also the effect of a certain tightness between fibers can be obtained.

At the same time, by increasing the pressure of the third roller, the draft amount in the middle area can be increased to about 2 to 3 times, thereby increasing the total draft multiple and obtaining good yarn quality.
