Description
Technical Field
The utility model relates to the technical field of textile equipment, in particular to a drawing frame drafting device in a staggered arrangement mode.
Background
The drawing process is an intermediate link of the spinning process flow and is a key process for improving the quality of finished yarn. The drawing frame is used for effectively controlling weight deviation of the fiber rods, improving uniformity, straightening degree and parallelism of the fiber rods, enabling fibers with different qualities to be mixed more uniformly in the fiber rods and creating conditions for obtaining good yarn formation.
The traditional drawing frame drafting device generally adopts a needle bearing, and the main reason is that the distribution positions of the roller and the section of the leather roller are compact in order to spin shorter fibers; the needle roller bearing is required to be matched with an axial limiting and sealing structure, and under the trend that the speed of a drawing frame is higher and higher, the high temperature problem of a drawing area is generated at a high speed, and the quality of fiber strips can be influenced by the high temperature.
In recent years, deep groove ball bearings are adopted for rollers and leather rollers of drawing frames, so that the problem of high temperature generated at high speed is solved to a certain extent. However, because the size and the structure of the drafting device are limited, the diameter of the bearing shaft in the drafting device is too small, the rollers in the drafting device need to rotate at high speed, and the bearing shaft with the too small diameter is easy to wear due to the high-speed rotation of the rollers, so that the conventional drafting mechanism of the drawing frame needs to frequently replace the bearing, and has limited service life.
