The roller shaft of textile machine is the key component of fiber drawing and conveying in textile production, and its surface smoothness and dimensional accuracy directly affect the fiber drawing uniformity and cloth quality. In the process of long-term high-speed operation, the surface roughness of roller shaft will be increased due to friction with fiber, erosion of cotton wax and attachment of environmental dust, resulting in worn grooves, and then uneven fiber stretching, uneven cloth and increased impurities in cotton knot, affecting product quality. The traditional polishing repair method will reduce the diameter of the roller shaft, affect the draft ratio, and the repair effect is short; Replacing a new roller shaft is costly and can lead to production interruptions. Based on the repair requirements of the roller shaft of the textile machine, the Dow Laser Cladding Equipment adopts the ultra-thin mirror surface cladding process to cladding an ultra-thin wear-resistant smooth coating on the wear surface of the roller shaft to accurately restore its surface smoothness and dimensional accuracy.
The flexible cladding head of the equipment can flexibly adapt to the thin and long structure of the roller shaft to avoid deformation of the shaft body during cladding. The surface roughness of the roller shaft after repair Ra ≤ 0.2 μ m, fully in line with the high-precision requirements of the textile industry, the dimensional accuracy deviation ≤ ± 0.01mm, to ensure the stability of the drafting ratio. The roller shaft of a cotton comber in a textile mill was previously worn and caused excessive impurities in the cotton yarn, and the strip evenness was only 2.5. After being repaired with the Dow laser cladding equipment, the impurities in the cotton yarn were reduced by 40%, and the strip evenness was improved to 1.5, and the product quality was significantly improved. The service life of the repaired roller shaft is 2 times longer, and the annual cost of spare parts saved is over 100000 yuan. Meanwhile, the repair cycle only takes 2 days, which is much shorter than the 7-day cycle of replacing the new roller shaft, effectively guaranteeing the continuity of textile production.
