摘要 针对梳棉机刺辊分梳时刺辊锯齿的螺旋倾角使得锯齿倾斜分梳纤维层,易加重纤维损伤的问题,以单个锯齿为研究对象,对嵌入式和自锁式刺辊锯齿的分梳过程进行深入的理论分析,采用建立力学模型的方法对螺旋倾角为0°和θ时纤维的受力情况进行研究。通过显式动力学模块对倾角为0°、1°、2°时锯齿的运动进行仿真。结果表明:当倾角为0°时,被梳纤维束所受的摩擦阻力及应力、应变均最小,且随着倾角的增大,摩擦阻力、应力及应变逐渐增大,束中纤维损伤越严重,纤维断裂概率越大;螺旋倾角的存在使得锯齿分解能力降低,易导致束纤维比例增大,分梳质量下降。 Spiral angle of the licker-in caused the fiber bundles to be combed by slant saw-teeth,which caused fibers to by more easily damaged during the carding process of the licker-in of carding machine.To solve this problem,single saw-tooth was regarded as an object of study,and the mosaic and selflocking carding process was theoretically analyzed. Fiber stress was researched by building mechanical model under condition of different spiral angles. Also,the carding process of single saw-tooth was simulated with explicit dynamics module when spiral angle was 0°,1° and 2°,respectively. The results show that when spiral angle is 0°,the friction force,stress and strain of fiber are smallest,and the larger the spiral angle,the more seriously the fiber is damaged,and the probability of fiber fracture is increased. Due to the spiral angle,the carding capability of single saw-tooth is declined,and the percentage of bundle fibers is increased,leading to the worse coming quality.
