Study On Filling Method Of TNT After Preparation

The expired discarded projectile body needs to be melted and taken out by steam heating method,and the liquid TNT agent is made into scaly solid TNT agent through special film making mechanism,and the follow-up filling and collection processing needs to be completed.According to the characteristics of the medicine after preparation,a full automatic filling production line is designed with the functions of lifting,bagging,weighing,sewing and conveying,as well as the explosion-proof and anti-static.The development of automatic filling production line can improve the processing efficiency,reduce the labor intensity of staff,and the most important thing is to avoid the health injury of staff.This paper discusses the principle of pharmaceutical filling production line after production in detail,using mechanical principle and automatic control technology to put forward the overall design of TNT pharmaceutical filling method after production,which is mainly composed of mechanical design part and automatic control part.The mechanical design part mainly includes the tablet lifting mechanism,automatic bag feeding mechanism,automatic weighing mechanism,automatic filling mechanism,automatic sewing mechanism and automatic transmission mechanism;Automatic control part mainly includes PLC program design,touch screen design.PLC is the main control core of the automatic filling system.The tablet lifting mechanism elevates the drug after the special film making mechanism to the specified height;The automatic bag feeding mechanism takes out the paper bag from the storehouse and opens the bag opening;The automatic weighing mechanism is to weigh the expected weight according to the demand;Automatic filling mechanism is to weigh the pharmaceutical filling into the paper bag;The automatic sewing mechanism is to pack the paper bag after filling.Automatic delivery mechanism is to deliver the packaged drug to the designated location.In today’s filling industry has already realized automation,this topic can draw lessons from many technologies.Such as agricultural automatic filling line,flour mill automatic filling line and so on.Different from the modern filling industry,there are pneumatic drive,anti-static,explosion-proof,special packaging bags and vacuum adsorption technology.Pneumatic drive This topic needs to solve is the pneumatic motor miniaturization,and the problem of integration of deceleration mechanism,through the comparison of vane type,piston type and gear type pneumatic motor,vane type pneumatic motor can easily achieve these two requirements.Anti-static technology,the application of anti-static skirt side belt,anti-static transmission brought to transport agents and packaging bags.Nonferrous metals are used in moving metal parts to eliminate the generation of electrical sparks.Pneumatic vacuum generator and vacuum sucker transport objects have been widely used,here to realize the adsorption and transport of anti-static packaging bags,opening the mouth of the paper bag can also be completed.Other actions are realized by ordinary cylinder and rotating cylinder.PLC technology,touch screen technology can be convenient to achieve automatic control.
