Product description

Parameters

The drafting lower roller of the cotton spinning frame produced by our company is made of famous brand No. 45 special high-quality carbon structural steel and advanced and unique processing technology, refined by modern special production equipment and high-precision processing center. The working surface is herringbone oblique densely toothed grooves and diamond mesh knurled. After high-frequency heat treatment, hard chrome plating and special polishing, the surface is smooth, burr-free, high-precision, rust-free, wear-resistant, and has a long service life. , And has the advantages of no hanging flowers, stable operation without moving, minimal bending deformation, stable holding force, ensuring effective control of fibers, and minimizing harmful roller mechanical waves that often occur when spinning high-count cotton yarns. It can significantly improve the quality of yarn evenness, reduce apron loss, and is suitable for heavy-pressure drafting.

Features of a new generation of super high-precision compact spinning roller without mechanical wave:

1. The flexural strength is increased by more than 9.1% compared with conventional rollers.

2. The static runout of any two rollers inlaid is 100% within 0.05mm, and no gasket is needed for installation on the machine.

3. Connect and tighten directly on the machine, without calibration, 98% of the dynamic runout is within 0.02mm, and the maximum does not exceed 0.03mm.

4. The roller has a non-mechanical wave rate of more than 98%, and more than 98% of the mechanical wave-drawn net is flat wave amplitude, and the maximum is not more than 3mm.

5. The yarn evenness of conventional spinning varieties is better than the 5% level of the 2007 Uster Bulletin.

6. Long-term use without walking, stable operation and good consistency.
