| Welding electrode is a kind of welding material, which is widely used in machine manufacturing and project construction. It consists of welding core and fluxes coated on the welding core. The composition of the flux and the level of the mixture uniformity are key factors in which determine the type, function and quality of the welding electrode. The accuracy of the composition and the mixture uniformity depends on the advancement of the dosing technology. Therefore, dosing technology is a key link in the manufacturing procedure of welding rod.The technology of automatic dosing production line for welding rod shell is an important means to raise productivity, improve accuracy of mixture, reduce the cost and raise the level of civilized manufacture and environmental protection. For a long time, many problems arising in the process of manufacturing, such as the blocking of the raw material flow, can not be solved properly, which seriously restrict the technology development of automatic dosing production line in China. In accordance with the practical requirement in the manufacturing process, we put forward this research project.In order to solve the technological problem of the dredge of raw material flow on the production line, we抳e carried out as overall theoretical and experimental research on the movement characteristic of the raw material on the surface of sifter in the vibratory machine, the dynamics property of the vibration stimulated by inertial double-axes, the flow property of raw material in these store hoppers, the agglomeration and obstruction mechanism.On the above research bases, we抳e proposed the optimized scheme of the raw material flow system of the production line, invented the high frequency vibrator and new type to prevent agglomeration store hopper. Thus, we抳e fundamentally solved the problem of low screening efficiency and blocking in raw material flow. The achievements in this research have achieved remarkable economic returns and social effect in production.
