Important factors affecting the performance of the spinning frame

The drafting bottom roller of the ring spinning frame plays a very important role in the performance of the whole machine:

① Roller mechanical wave is related to its installation, adjustment, cleaning, improper bearing press fit, its own material, surface quality, tooth profile error, etc.;

② The future development direction is to manufacture and select rollers with different requirements for different spinning processes;

③ The quality of roller products ultimately depends on the design, process technology, equipment and quality system level of the manufacturing enterprise.

The drafting bottom roller of the ring spinning frame plays a very important role in the performance of the entire spinning frame. In recent years, with the continuous improvement of roller design and manufacturing level, the quality and performance of the spinning frame roller have been greatly improved. In the spinning process, roller spinning mechanical waves can be roughly divided into three categories: harmful mechanical waves that are 8mm higher than the fundamental wave; harmless mechanical waves that are 5mm-7mm higher than the fundamental wave and slight mechanical waves that are 5mm higher than the fundamental wave.

With the improvement of textile enterprises’ requirements for the quality of spun yarn, the performance requirements for roller products are also getting higher and higher. During the spinning process, it is not allowed to produce roller spinning mechanical waves that are more than 5mm higher than the fundamental wave. Mechanical waves also require control within a certain range. Therefore, roller manufacturing companies must continue to develop and manufacture high-precision products to meet the rapidly developing market demand.
