大枣去核机的设计
摘要
随着生活质量的改善，人们对养生保健的需求日益增长，大枣制品被越来越多的人喜爱。如枣泥、枣干、大枣牛奶等等制品。去核是很多果类加工的处理工序,对于大枣而言,去核加工尤为重要。随着加工工业的发展，各类大枣制品需求上升，自然对食品质量也十分注重。因此，大枣去核机，将注重提高去核的效率，以及果肉的干净与完整。以此为目标，去设计合理的机械。要求全自动，多方位。通过分析比对当前市场上的一些大枣去核机，确定要解决的主要问题，即冲击力度太大，导致果肉破碎，亦或者是冲击力度太小，不能完整去核。除此之外，还可能出现一些定位出现偏差，导致整体运动出现衔接不良等等问题。
本文主要内容，整体传动方案设定，确定运动方案，对执行机构零件，进行尺寸计算。为了确保去核机的各部分设计的科学性、合理性，利用CAD等绘图软件，对槽轮机构、链轮机构这两部分，作着重研究说明。包括运动特性，配合性等等。
本机主要构成部分有传送带、冲核机构、槽轮机构等。用合理的联结方式，使槽轮机构与曲柄滑块运作，带动冲核杆，对大枣进行精确冲核，提高生产效率。
通过根据初始数据的计算，选择合适的电动机。根据所确定的传动比，分析传动零件的具体参数。除此之外，还要对V带传送做进一步分析。根据查表与已知数据相结合，确定中心距、带速、基准长度等参数，进而确定V带的类型。对执行机构中的冲压机构进行分析。大枣从枣斗进入后，首先要进行定位，使做间歇运动的旋转盘工作台与上下往复运动的冲针相互配合，使去核更加准确高效。再依次对轴系零件进行计算并校核，如轴疲劳强度的校核计算，键联结的校核计算，等等，进而选择合适的滚动轴承。
最后选择合适的润滑方式，对传动系统零部件进行润滑与密封。

Abstract
With the improvement of quality of life and the increasing demand for health care, jujube products are loved by more and more people. Such as jujube mud, dried jujube, jujube milk and other products. The core removal is the processing procedure of many fruit processing, especially for the red jujube. With the development of processing industry, the demand for all kinds of jujube products is rising. Therefore, jujube denuclearization machine,will focus on improving the efficiency of de-nucleation, aswell as pulp clean and complete. With this as the goal, to design reasonable machinery. Full automatic, multi-directional. By analyzing and comparing some jujube denuclearization machines in the current market, it is determined to solve the problem. The main problem is that the impact is too strong, resulting in pulp broken, or too small to be completely demineralized. In addition, there may also appear some positioning errors, resulting in the overall movement of poor cohesion and other problems.
The main content of this paper, the overall transmission scheme setting, determine the motion plan, the actuator parts, size calculation. In order to ensure the scientific and reasonable design of each part of the denuclearizer, this paper mainly studies and explains the slotwheel mechanism and the sprocket mechanism by using CAD and other drawing software. Including the characteristics of motion, coordination, and so on.
The main components of the machine are selected roller, conveyor belt, punching mechanism, troughwheel mechanism and so on. Using reasonable connectionway, the groovewheel mechanism and crank slider operate, drive the punching rod, carry on the accurate punching of the red date, and improve the production efficiency.
According to the calculation of the initial data, the suitable motor is selected. According to the determined transmission ratio, the specific parameters of the transmission parts are analyzed. In addition, V-band transmission should be further analyzed. According to the combination of look-up table and known data, the parameters such as center distance, bandvelocity and datum length are determined, and the type of V-band is determined. To carry on the analysis to the punching mechanism in the executive mechanism. After entering the jujube bucket, the jujube should be positioned first, so that the rotating tablewith intermittent movement can cooperatewith the punching needle of the reciprocating movement, so that the nucleation can be more accurate and efficient. Then the shafting parts are calculated and checked in turn, such as the fatigue strength of the shaft. Key connection check calculation, and so on, and then select the appropriate rolling bearing.
Finally, the proper lubrication method is chosen to lubricate and seal the parts of transmission system.
