Design And Research Of Fully Automatic Integration Feeding System

Based on the feed industry generally adopts the bagging method for the collection,distribution and palletizing of powdered and granular materials and the subsequent material feeding process still uses artificial feeding that has a large labor intensity,low efficiency,high cost,poor environment and other backward status,the paper innovatively researched and designed an automatic integration feeding system that integrates multi-function such as catching,lifting,conveying,bag breaking,material clearing,arch breaking,trays conveying,trays stacking and so on.The main research content,methods and conclusions of the topic:(1)On-site observe the action and requirements of dismantling the artificial feeding process and designed the overall plan of feeding system.Determined to use standard trays 1600mm×1600mm of the enterprise with annual output of 30-50 tons of livestock and poultry feed as pallet load,which obtained the technical performance parameters of the feeding system: productivity ?1200 bags/h,and the empty bag emptying rate ?99.99%.(2)Based on the design of the overall plan,the organization,structure,and parameters of each functional unit were optimized design.Using SolidWorks software,a three dimensional model of the mechanical system was established,and a full set of engineering drawing of the prototype was completed.(3)Using ADAMS software,the dynamics analysis of the lifting platforms of the material and lifting platform of stacking trays was carried out to verify that it satisfies the working conditions and the smoothness and stability of its work.And provide boundary conditions for the static analysis of the subsequent material lifting platform.(4)Using ANSYS software,the finite element analysis was performed on the critical parts of the feeding system at the time of maximum load,and the maximum position and value of the stress strain were obtained,and their structure and parameters were optimized to reduce the weight of the whole machine by 854.7kg.The modal analysis of the lifting platform has obtained its natural frequency of 21.04 Hz,which provides a theoretical basis for the design of the vibration frequency of the cleaning mechanism.The methods and conclusions of the research will provide a theoretical reference and practical application value for the automatic bag breaking and feeding system for grain and oil,food and chemical and so on industries.
