AI Technical Summary

Technical Problem

The existing upper roller design causes the BOSS component to become unbalanced during continuous operation, resulting in uneven sliver output and affecting yarn quality. Furthermore, the traditional design has shortcomings in terms of service life and maintenance costs.

Method used

Employing a multi-track ball bearing system, the system distributes three or more ball bearing tracks across the BOSS span, combined with a custom groove and locking nut mechanism, to achieve uniform load distribution. Furthermore, the system enhances component rigidity through heat treatment, supporting a detachable and repairable design.

Benefits of technology

It achieves high stability and durability of the upper roller, extends service life, ensures consistent yarn quality, reduces maintenance costs and downtime, and improves the production efficiency of textile mills.

Abstract

The present disclosure relates to a multi-track ball bearing system for the top roller in the textile industry. The multi-track bearing system has been developed with a core concept of a detachable and serviceable design to achieve the highest quality impact on the extracted sliver and yarn. Textile spinning mills will benefit from low maintenance by avoiding repeated roller replacements and achieving consistent quality in the sliver and yarn output to effectively serve their end customers. The design also allows for repair and recycling by reusing good functional parts and replacing worn-out parts. This can be done by the top roller manufacturer as needed and ultimately reduces the environmental impact due to the inherent benefits of recycling.
