JR1000A绞肉机的结构设计 摘要 本文主要论述了小型肉类加工器具—JR1000A绞肉机绞肉机的工作原理和它的技术参数，生产能力分析及主要结构设计计算。 此绞肉机采用全封闭联轴器传动方式，具有较高的防护等级，运转平稳，工作可靠，而且拆洗方便，不但可以用于家庭绞肉使用，还可以用来绞碎瓜果，辣椒，碎冰等食物。它所需的功率比较小，采用电力驱动，合理的结构合计能满足普通家庭食品绞碎工作。 此绞肉机主要是依靠绞肉刀高速旋转和挤肉样板上的孔眼刃形成的剪切作用将肉绞碎，并在螺杆的挤压下将原料排出机外。可以根据肉料特性配置不同刀具和孔板，即可以加工出不同尺寸的肉颗和肉泥，满足不同肉类加工需要。 关键词：绞肉机；结构设计；绞刀 Abstract This paper mai
