摘要 红枣是大多数人尤其女性爱吃的食物，其对人体身体健康具有明显作用，而现代对红枣的加工引用了自动化技术，出现许多红枣去核切片机器，但其切制的红枣片厚度不均，枣肉破碎率高，枣核残留等问题，同时需要人员辅助运行，劳动强度高，自动化程度低，故急需更加智能、可靠的新型红枣去核切片机，红枣切片机可大大减轻劳动强度，生产效率高，使用省力，符合食品加工机械卫生标准要求。切割后成品表面光滑、不破坏组织。匀称，切割速度快，减少劳动成本。 本文通过机械结构的角度设计了红枣切片机集成，拥有红枣自动定向排序、夹紧去核、枣肉切片等功能，由辊筒输送链供料、采用槽轮结构间歇夹紧，;采用两排平行放置的链实现定位和夹紧;去核装置采用对心曲柄滑块机构来实现;采用刀具固定,刀槽式送料轮旋转实现切片。 本文设计的机器有序上料率大幅度提高，除去核和切片中意外的破碎率大大降低，设备结构简单，方向效果好，制造成本低，生产率高，适应性强。 关键词：红枣；间歇上料；去核；切片 Abstract Red jujube is a favorite food for most people, especially wome
