Design and Simulation of Bag Clamping Mechanism of Raw Grain Packaging Machine
摘要
Abstract
In order to further improve the transmission performance of the bag clamping mechanism of the semi-automatic raw grain packaging machine in actual production and investigate the synchronization of the movement of the front and rear nozzle splints of the bag clamping mechanism,this article optimizes and designs an electrically driven bag clamping mechanism,and analyzes the bag clamping force and driving force in the process of bag clamping.The pull rod four-bar mechanism and push rod four-bar mechanism of the bag clamping transmission mechanism are optimized by using the main objective method and hierarchical sequence method of multi-objective optimization design,based on the optimiza-tion design function of MATLAB.The three-dimensional model of the bag clamping mechanism is established by using CATIA,and Adams is used for simulation analysis.The simulation analysis of bag clamping motion shows that the angu-lar displacement of the front and rear nozzle splints of the bag clamping mechanism is 16.25 ° and 15.99 °,and the simulation results are consistent with the theoretical value of 16 °.The simulation results of the transmission angle of the pull rod four-bar mechanism and the push rod four-bar mechanism are 42.93 °~56.32 ° and 44.50 °~65.18 °,which are basically consistent with the optimization results of the transmission angle of 42.97 °~56.35 ° and 44.35 °~64.97 °,and both meet the design requirements that the minimum transmission angle is greater than 40 °.The results verify the rationality of the design of the bag clamping mechanism and the synchronization of the movement of the front and rear nozzle splints.关键词
