Research And Development Of High Efficiency Weighing And Grading Device For Marine Products

For the rich nutrition,high price of the sea treasures,the high efficiency and accuracy of the weighing and sorting system is particularly important.In this paper,the high efficiency and high precision of the dynamic transmission and high precision weighing is combined to complete the high efficiency and accuracy of the Sea Treasures weighing and sorting system.The system uses the transmission belt to complete the uninterrupted transmission of the material,the material is arranged in a row,the static weighing of the material is finished,and the weight of the high efficiency and high precision.This thesis completes the design of the mechanical structure design,hardware design,control strategy and software development of the weighing system.The control system adopts the man-machine interface(HMI)and PLC.The control system is simple,reliable and has high reliability,and has a high degree of visualization.In the development of control strategy and the preparation of control software,the full consideration of the material transportation and scheduling of various conditions,to ensure the normal operation of the system.And through the cooperation with the enterprise,complete the manufacture of the prototype,in the high-speed operation of the prototype,the weighing accuracy and the static weighing sensor are the same,verify the high efficiency and accuracy of the weighing system.In the process of weighing the prototype.
