The Design And Simulation Analysis Of The Reed Balers’ Key Mechanism Structure

Reed is a high quality non-wood fiber raw materials for paper, but also one of the important raw materials of paper industry. Production base of reed always far away from the paper-making companies and raw materials can not be supplied economic and timely to paper companies, increasing transportation costs become the major bottlenecks for paper-making enterprises enlarge scale and improve efficiency in Xinjiang. The reeds pressed into high-density package is an effective way to reduce the cost of transport, The packing density of reed is closely related to the work performance of the baler, Therefore, research and analysis of this article is mainly for high-density baler reed key mechanism, The main contents include:(1) To analyze the factors affecting compression density of the reeds, With closed compression method for compression tests on three factors include the amount of feed and compression rate and moisture content affect compression density, a significant degree of factors affecting reed compression density in descending order of amount of feed, compression speed, moisture content. Under the experimental environment the optimum effect of compaction can be implemented when moisture content of17%and feeding amount of550g and the compression speed10mm/min, The results showed that in the actual packaging process,in a certain scope to improve amount of feeding, give priority to low compression rate and high moisture content can be increased packing density.(2) By analyzing the requirements of reed packer operation function of the key mechanism-the feed compression mechanism designed and modeled, calculation to determine the eccentricity, crank and crank rod length respectively is130mm,273mm and1048.5mm,And proof the design reasonable by verifying minimum transmission angle, the model quality analysis and interference analysis to determine the model does not exist interference, by the kinematics and dynamics simulation analysis of feeding compression mechanism, get changes in displacement and velocity as well as key parts of the hinged force between the two in the case of mutual synergy, feeding movement and compression action sequence difference was0.085seconds with accuracy to meet the requirements, get the sweep locus of feed mechanism and the forks and the four outer limit position of feeding fork in the XY plane, swept area between0.1m2to0.2m2,the highest point in the feeding fork, fork and fork sets of crank shaft hinged at maximum force, failure or damage is most likely to occur here.(3) Based on the finite element method and using ANSYS software to extracts and analyzes crank rod natural frequencies and mode shapes under10freedom modal and constraint modal by modal analysis, The results show that the deformation position of the crank rod more likely location at the center and both center-symmetrical sides of link in the actual work process. Establish rigid hybrid model compression mechanism in ADAMS, the speed and force of the rigid model and rigid hybrid models were analyzed, the analysis results show that the speed and force the rigid hybrid systems are large fluctuations in the system start, duration of about0.05seconds, the rigid hybrid models when stability basically consistent with the rigidity system In terms forces and movement, the maximum amplitude of the amplitude difference of not more than0.5%;Simulation results show that the rigid hybrid model is more in line with engineering and high precision.
