螺旋果蔬榨汁机的设计

洛阳理工学院毕业设计（论文） I 螺旋果蔬榨汁机的设计

摘 要 摘要：因为我国的果蔬加工业近年来取得了很大的成就，果蔬加工业在我国农产品贸易中占据了重要的地位。所以，果蔬榨汁机也相应的出现，而本次设计的对象就是螺旋果蔬榨汁机，该螺旋果蔬榨汁机通过螺杆不同程度的挤压从而达到充分榨汁效果。螺旋果蔬榨汁机的设计主要包括螺杆，带轮以及过滤网等，在设计中由于要保证各个部件要安装合适，故经过一系列的计算数据来达到所需的要求。特别是螺杆的设计，螺杆采用不同的螺距以及断面大、小径的不等来使果蔬压榨的更充分，更高效。该果蔬榨汁机结构简单，方便实用，效率高等优点，由于采用的材料都相对便宜，故成本相对较低。

II Design of spiral fruit and vegetable juice squeezing machine

ABSTRACT ABSTRACT：Press calculation due to the juice is the object of China's fruit and vegetable processing industry in recent years has made great achievements, fruit and vegetable processing industry in China's agricultural products trade occupies an important position. So, fruit and vegetable juice machine corresponding, and the design of the spiral vegetable juicer, and the juice through a screw of compression fault so as to achieve the effect. Juicer design comprises a screw rod belt wheel and a filter net, etc., in the design to ensure that the various components to install appropriate, therefore, after a series of data to achieve the desired requirements. Especially screw design, screw with different pitch and large section, trails, ranging from to make fruits and vegetables more fully, more efficient The fruit and vegetable juice squeezing machine has the advantages of simple structure, convenient and practical use, and the cost is low due to the relatively low cost of the materials used.
