Fireworks Black Drug Man-machine Isolated Analysis And Research Of Automated Production Equipment

At present, the fireworks devices in our country are in the disadvantages of low degree of automation, workers involved in many production operations and so on. Automatic control technology is not better integrated into the equipment design and manufacturing, and there is also lack the necessary security and supervision.For the risk factors and the backward status quo of prevention facilities in the preparation for the fireworks black powder, according to the black powder production process of Jiangxi Lidu fireworks corporation, paper mainly focused on black powder mixing equipments associated with the man-machine isolation, established three-dimensional model and assembly model of fireworks black powder man-machine solution automatic equipment; According to he preparation process of black powder and workflow of the equipment, PLC are used to control the work process of the equipment, and the structure program of the monitoring system are showed, functions of each part elaborated; several states of motion of balls in the drum were introduced, parameters of equipment affecting the ball crushing and mixing analyzed, and according to the forced feature of single ball, movement situation and acting situation of ball was analyzed; Finite element model of three collisions occurred in the work of equipment were established, the numerical calculation and analysis conducted, and the force feature of impactors were analyzed. There was a certain significance to the study of the crushing effects of black powder and damage of equipment. Running test of prototype of fireworks black powder man-machine solution automatic equipment was carried out. The results showed that the equipment can automatically complete fireworks crushing, mixing, screening process of black powder, and have man-machine isolation function and safety controlling and monitoring functionThe equipment has been put into use and applied to the actual production of fireworks black powder. The operation of the equipment is reliable, and safety and productivity targets are achieved.
