摘　　要：为降低传统环模成型机的能耗,设计了一种齿辊式环模成型机,并对该成型机的运动干涉、最大攫取角进行了理论分析。结果表明按照设计尺寸运动并不干涉,最大攫取角大于普通环模;在该样机上以含水率8%～20%四倍体刺槐颗粒为原料进行了成型对比试验,结果表明：不同含水率下的平均比能耗为56.82 k W·h/t,成型密度为1.085 g/cm3,比同样结构的普通环模产量提高了3.36%～6.25%,能耗降低5.77%,密度提高3.33%,同时发现在含水率16%、转速200 r/min时比能耗最低,为50.3 k W·h/t。To increase the energy-efficient performance, a forming machine with geared-roller annular mould was proposed. Based on the analysis of mechanism kinematics, the motions of geared roller and annular mould were non-interference with each other. Compared with normal annular mould, a larger grab angle in the structure was good for enhancing the production efficiency. Particles of locust, of which moisture content were 8% -20% , were taken as raw materials. The experimental results showed that the specific energy consumption was 56.82 kW· h/t and the formation density was 1. 085 g/em3. Correspondingly, the output was improved by 3.36% -6. 25% , the energy consumption was decreased by 5.77% and the density was increased by 3.33%. Meanwhile, the energy consumption was 50. 3 kW＇h/t with the moisture content of 16% and speed of 200 r/min.
