摘　　要：根据微颗粒刀具盘切削橡胶颗粒制备超细胶粉的原理,结合普通结构螺杆头输送橡胶颗粒存在的缺陷,设计了特殊结构的螺杆头和阿基米德曲线料道,研究了料道输送橡胶颗粒的原理。结果表明,设计的特殊结构螺杆头降低了橡胶颗粒进入阿基米德曲线料道进料口的阻力,提高了物料输送效率,同时避免了橡胶颗粒在螺杆头部形成死料和摩擦热积聚等问题;设计的阿基米德曲线料道利用切削刀具的动力牵引橡胶颗粒运动,使颗粒料流更加顺畅,提高了胶粉的生产效率;理论计算证明使用阿基米德曲线料道输送橡胶颗粒是可行的。Based on principle of preparing ultrafine rubber powder by cutting rubber particles with a micro-particle cutting tool disc,combined with defects of ordinary structure screw head in conveying rubber particles,a special structure screw head and Archimedes curve channel were designed,and the principle of conveying rubber particles in the feed channel was studied.The results showed that the specially designed screw head reduced the resistance of rubber particles entering the Archimedes curve inlet,improved material conveying efficiency,and avoided problems such as dead material and frictional heat accumulation of rubber particles at the screw head.The designed Archimedes curve channel utilized the power of cutting tools to pull rubber particles,making the particle flow smoother and improving the production efficiency of rubber powder.Theoretical calculations proved that it was feasible to convey rubber particles using Archimedes curve channel.
