Detection and control device and method for powder adding height of powder charging pipe of gas generator

Abstract

The invention discloses a detection and control device and method for the powder adding height of a powder charging pipe of a gas generator and belongs to the technical field of detection and control of the powder adding height of the powder charging pipe of the gas generator. According to the device, the compaction degree between gas generating powder pieces in the powder charging pipe can be adjusted, the clearances between the gas generating powder pieces are uniform, and the powder adding height can be detected. The device comprises a support, a powder input unit, a first motor, a second motor, a tumbler, a lifting rope, a pull frame with an opening formed in the lower end, a vertical pipe and a controller. The vertical pipe shakes under rotation of the tumbler, the vertical pipe rolls under rotation of the second motor, and the vertical pipe sieves under sieving of a sieving generator; and the compaction degree between the gas generating powder pieces in the powder charging pipe is adjusted, the clearances between the gas generating powder pieces are uniform, and the powder adding height can be detected in a shaking manner, a rolling manner and a sieving manner. The detection and control device and method are mainly used for the gas generating powder piece adding technology of the powder charging pipe of the gas generator.

Description

technical field [0001] The invention relates to the technical field of detection and control of the dosing height of a gas generator charge tube, in particular to a detection control device and a detection control method for the charge height of a gas generator charge tube. Background technique [0002] At present, the dosing amount of the gas-generating tablets in the gas generator charging tube is completely based on visual inspection, which not only makes it difficult to grasp the dosing amount, but also makes it difficult to control the gap between the gas-generating tablets. [0003] The amount of gas-generating tablets added to the gas generator charging tube has a crucial impact on the performance of the gas generator. If the amount of gas-generating tablets added is too small, it will not only affect the explosive performance of the gas generator, but also cause a large gap between the gas-generating tablets after assembly, and even leave room for the gas-generating ...

Problems solved by technology

[0005] The present invention aims to solve the problem that the dosing amount of the gas-generating tablets added to the charging tube of the existing gas generator depends entirely on visual inspection, which not only makes it difficult to grasp the dosing amount, but also makes it difficult to control the gap between the gas-generating tablets, and provides The utility model can not only make the compression degree between the gas-producing tablets in the drug-filling tube adjustable when the gas-generating tablets are loaded, but also can make the gap between the gas-producing tablets uniform after the gas-producing tablets are installed in the drug-charging tube, and can also A gas generator that can detect the dosing height of the gas generator after the gas-generating tablet is installed in the charging tube and the drug-filling height detection control device and detection control method
