双刀式哈密瓜自动削皮机的设计与试验

当前哈密瓜去皮主要是以人工削皮为主,不但效率低下,而且存在一定的卫生安全问题,严重阻碍了相关企业哈密瓜产品的创新与发展。为了降低工人劳动强度,提高哈密瓜的去皮效率以及机械化和自动化程度,依据哈密瓜果皮粗糙坚硬的物理特性,设计出了一种双刀式哈密瓜自动削皮机。该削皮机外刀可调节削皮厚度1~5mm,内刀可调节削皮厚度3~15mm,锯齿状的内刀与外刀所构成的双刀式组合机构,能够适应各种不同品种的哈密瓜。通过设计计算,确定了仿形弹簧的伸长量为40.68mm,抱果夹的夹持力要大于51.96N。为了确定影响哈密瓜削皮效果的关键因素的最佳组合,通过正交试验分析数据并借助SPSS软件对试验结果进行相关性分析,确定了3种因素影响削皮效果的主次顺序为A(驱果电机频率)>B(削刀电机频率)>C(入切角),最佳因素水平组合为A₂B₂C1。

Design and Experiment of Double Dnife Automatic Peeler for Hami Melon

Due to the current Hami melon peeled mainly by manual peeling,not only the efficiency is low,but also there are some health and safety problems,which seriously hindered the innovation and development of Hami melon products of related enterprises.In order to reduce the labor intensity of workers,improve the current efficiency of Hami melon peeling,and improve the degree of mechanization and automation of Hami melon peeling,this paper designs a double knife automatic peeling machine for Hami melon based on the physical characteristics of rough and hard peel of Hami melon.The outer knife of the peeler can adjust the peeling thickness of 1-5mm,and the inner knife can adjust the peeling thickness of 3-15mm.The double blade combination mechanism composed of serrated inner knife and outer knife can adapt to different varieties of Hami melon.Through design and calculation,the elongation of profiling spring is 40.68mm,and the holding force of fruit holding clamp is greater than 51.96N.In order to determine the best combination of the key factors affecting the peeling effect of Hami melon,the orthogonal test was used to analyze the data,and SPSS software was used to analyze the correlation between the test results,and the best factor level combination was A₂B₂C1.
