Automated grain-airing aging device for propellant high in slenderness ratio

Abstract

The invention relates to an automated grain-airing aging device for propellant high in slenderness ratio and belongs to the field of mechano-electronic automation. The device comprises a first motor, rolling wheels, conveying belts, roll shafts, a second motor, gears and chains. The two rolling wheels are fixedly connected through a connection rod. The two parallel rolling wheels are movably connected with the conveying belts. The connection rod of the rolling wheels is connected with the first motor. Connection blocks are fixedly connected to the conveying belts. Each connection block is provided with two through holes which are used for placing corresponding shaft rods therein. Each shaft rod penetrates one end of the corresponding through hole and is fixedly connected with the corresponding driving roll shaft, and the other end of each shaft rod is fixedly connected with the corresponding gear. Each driving roll shaft is movably connected with the corresponding driven roll shaft. After each driven roll shaft is fixedly connected with the other corresponding shaft rod, the shaft rod is placed in the other corresponding through hole. Each gear occludes with the corresponding chain. Each chain is engaged with the corresponding gears fixed to a support. By means of the automated grain-airing aging device, under the circumstance that safety is guaranteed, continuity, automation and man-machine isolation of the grain-airing aging production process are achieved; and the continuous aging device is provided with a breeze circulating system and a system through which the temperature and the temperature rising rate can be controlled in a remote distance.

Description

technical field [0001] The invention relates to an automatic drug drying and aging device for propellants with a large slenderness ratio, belonging to the field of mechanical and electronic automation. Background technique [0002] The traditional drying process needs to go through the following steps: [0003] (1) Naturally airing the blank powder column extruded by the mold from the stretching machine to the specified time, so that the nitrocellulose polymer material in the charge formula is fully rebounded; [0004] (2) After the pressing and stretching is completed, the blank powder column that has passed the manual inspection is manually stamped with the specified drug column number with a steel drill according to the requirements, and then immediately packed into the plastic aluminum cylinder and sent to the workshop for drying the drug; [0005] (3) Manually place the aluminum tube with the powder on the drying table, and after 48 hours, take the blank powder out of ...
