| The last process of industrial production of zinc ingots is the finishing and packaging of zinc ingots.The necessary equipment for binding zinc ingot materials is a fully automatic zinc ingot bundling machine.In the international non-ferrous metal trading market,the finished products being traded will have strict packaging and binding specifications.The quality and sales performance of zinc ingots are largely affected by the packaging quality of zinc ingots.An important factor in the development of an enterprise and economic benefits is the quality of packaging and binding of zinc ingots.At present,only a few developed countries can be familiar with and master the complete automatic bundling technology.As a big country in the non-ferrous metal industry,my country cannot independently develop fully automatic bundling machines.This fact makes my country’s non-ferrous metal manufacturers spend a lot of money on the import of bundling equipment and spare parts every year.Traditional semi-automatic and manual bundling methods have the disadvantages of low bundling efficiency,high work intensity,and poor convenience.In order to better meet the needs of the market,the specifications of zinc ingot packaging and strapping have gradually become stricter.Based on the ready-made technology and production basis,the research on the key components of the fully automatic zinc ingot tying machine is very important.Taking the automatic zinc ingot bundling machine on the assembly line of the Northwest Lead and Zinc Smelter in Baiyin City,Gansu Province as the research object,for the problems of incomplete belt delivery and incomplete tightening of the belt during the production process of the baler,through bundling The movement principle analysis and structural improvement and innovation of the strapping machine will ultimately solve the problems of the strapping machine’s belt tightening,so as to adapt to the production line to improve the efficiency of zinc ingot stacking.The focus of this thesis is to take the belt-feeding and tightening mechanism in the head of the core component of the fully automatic zinc ingot strapping machine as the research object.Through searching for relevant information,three-dimensional modeling,theoretical analysis and simulation,and combining with actual production For the problems in the process,research and analysis of the bundling process,overall structure and strapping mechanism of the automatic zinc ingot baler,and obtain the key elements that affect the development of the fully automatic zinc ingot baler.According to the study of this subject,the bundling and forming of zinc ingots mainly include the steps of automatic stacking,belt feeding,clamping of the steel belt lead by the jaws,winding up,tightening,locking and cutting,and resetting.The topic of this paper is to analyze and research the optimization design of the strapping machine’s belt tightening friction mechanism.The main research object is the strapping machine’s belt feeding and tightening device,so the components of the strapping machine’s belt tightening mechanism need to be implemented.Measurement,three-dimensional modeling,and analysis of the processing and manufacturing of the various components of the mechanism show that the manufacturing process requirements for the components of the belt feeding mechanism are relatively high.Through the movement simulation analysis of the belt-feeding and tightening mechanism,it can be seen that the friction mechanism analysis and research of the action process is the key and difficult point.Also,the finite element analysis of the belt-feeding and tightening mechanism shows that the stress-strain analysis has a significant effect on the fatigue and fragility of the mechanism.With further understanding,the belt-feeding and tightening mechanism can be improved and optimized,and finally the bundling efficiency of the strapping machine and the packaging quality of zinc ingots can be improved. |
