Design And Application Of Jujube Corer

Because jujube has rich nutritional and has a huge application value in the field of food,so early processing and deep processing of jujube products has become the current theme of the food industry.For the processing of jujube,pitting and slicing are more important aspects,based on the processing requirements of the pitting and slicing,this topic needs to develop a jujube processing equipment that can automatically accomplish large the pitting and slicing process of the batch of dates jujube,So a jujube pitting machine will bring great convenience to the process of pitting and slicing of jujube,and greatly improve the processing efficiency.This topic for jujube pitting machine mainly includes the followingBased on the in-depth analysis of the physical characteristics of jujube,the process of jujube processing was determined.According to the processing flow of jujube,the overall scheme of jujube was determined.In the two schemes of preliminary design,we chose the more feasible intermittent jujube pitting machine program.Then according to the overall plan of the jujube pitting machine and the form of the movement during its working process,the transmission system is designed to meet the overall program and the related parameters in the transmission system are determined.Design jujube pitting machine mechanical structure.According to the jujube processing flow and transmission system design jujube pitting machine key mechanical structure,the use of Pro/E software on the jujube pitting machine key mechanical structure modeling.The mechanical structure of the jujube pitting machine according to their functions are mainly divided into jujube transmission mechanism,auxiliary feeding agencies,pitting institutions and slicing agencies.On the jujube pitting machine's kinematic simulation analysis of various agencies,obtained in the course of the movement of the various agencies characteristic curve to avoid interference with other institutions,according to the analysis of its movement on the function,verify the overall movement of the jujube pitting machine Consistency and coordination.Then the modal analysis of the whole frame was carried out to obtain the modal frequencies and mode shapes of the various stages.Compared with the exciting frequency of each moving mechanism of the jujube pitting machine,the vibration characteristics were obtained.Based on the structure of the rack to optimize the design and reduce the impact of vibration on the whole jujube pitting machine.Design jujube pitting machine control system,PLC-based control system includes hardware design and software programming.Then the prototype installation and commissioning and production tests to verify the performance of key organs of the jujube pitting machine.
