果蔬三维切丁机切片部件的研究与设计 摘要：蔬菜，如萝卜、马铃薯、青菜等，含水分高且外形形状不规则，且质地有所不同，因而给其机械装夹，切丁作业带来不便。针对国内现有切丁机械切丁大小限制及其切丁形状的要求，在分析了国外切丁机械的基础上，结合其物料特性，设计了一种新型果蔬三维切丁机满足企业的需求。 课题来源于泰州市科技攻关项目（BE2008385），针对现有切丁机不能切大丁，切丁形状不规则这一难点进行分析。切丁机切丁过程分为切片、切丝和切丁三个步骤，大大提高了生产效率。切片机构采用带有挡板的旋转滚筒作为进料装置，依靠固定在滚筒外壁的定刀实现切片动作。利用离心力实现物料的夹紧，适用于各种形状和大小的物料。 关键词：切丁机、切片、物料特性、调整装置 Study a
