摘要
为了研制高效、实用、可靠的大枣去核设备,通过对大枣去核原理的分析,设计了一台大枣去核试验机.该机采用滚珠丝杠螺母副机构带动去核刀具往复运动实现去核作业;采用设计的专用夹具实现大枣的自动定位和夹紧.样机试验表明:在大枣去核时,去核刀具的直线进给速度对大枣造碎率的影响显著;正交试验表明:最佳的大枣去核参数为含水率67.23%、直线进给速度72mm/min、去核刀具的壁厚0.5mm.
In order to develop efficient ,practical and reliable pitting device for jujube ,through the analysis of the principle of the jujube denuclearization ,a automatic pitting device for ju‐jube is designed .Using ball screw nut pair mechanism drive pitting tool to do reciprocating movement to realize denuclearization .The positioning clamp was performed by special fix‐ture .It was showed that the linear feed speed of pitting tool has significantly influence on broken rate for jujube .By the orthogonal test ,we can see the best pitting parameters of ju‐jube ：moisture content is 67 .23% ,linear feed speed is 72 mm/min ,cutting knife thickness is 0.5mm.
