摘　　要：探讨精梳机变速梳理与恒速梳理的技术特点。对比分析了两种梳理技术的优缺点。指出:采用锡林轴瞬时变速技术使大齿面角锡林的使用成为可能。分离罗拉顺转定时、锡林定位和钳板闭合定时三项工艺参数调节范围的扩大并不会造成有效纤维的流失,具有节棉优势。其缺点是锡林产生的加速度大,机器振动大、耗电量大、不利于高速。恒速梳理的精梳机不产生加速度,具有机器振动小、耗电少、有利于高速的优势,由于锡林恒速梳理区间较大,使上述三项工艺参数调整的空间相对较小,调节不当往往会造成落棉率增加、有效纤维流失,增加纺纱成本。认为,恒速梳理可采用同时兼容齿面角为90°和110°的锡林托架,以大幅度提高梳理效果,增强排除短绒和结杂质的能力,可借鉴变速梳理实现高速稳定运行的技术措施,实现进一步的改进和优化。所具有的节棉优势使变速梳理技术仍然是精梳机生产厂商今后的重点研发方向。Carding technology properties of comber at change speed and constant speed were discussed. Theadvantage and disadvantage of two kinds of carding technologies were compared and analyzed. It was pointed outthat the use of instant speed change technology in cylinder axle leads to the possible of adopting cylinder with biggear angle. The enlargement of adjusting range for three technology parameters of timing by roller veering, cylin-der positioning and timing by nipper closing will not cause the loss of effective fibers,the advantage of cotton sav-ing is obvious,the disadvantages include bigger acceleration, larger machine vibration, more power consumptionand worse to higher speed running. Comber working at constant speed would not generate acceleration. The ad-vantages is obvious like smaller machine vibration, less power consumption and better to higher speed running.Due to bigger carding district of cylinder at constant speed,the adjustment range of the above three technology pa-rameters are relatively smaller. If the parameters are not adjusted properly, waste percentage will be increased, effective fiber would be lost and spinning cost would be increased. It is considered that carding at constant speed cancombine cylinder bracket with gear angles of 90° and 110° at the same time to improve the carding effect greatly.The ability of removing short fiber, neps and impurity strengthened. Technology measures of stable running athigher speed can be achieved by referring carding at change speed. Further improvement and optimization can berealized.
