An online measurement system for material particles

Abstract

The invention discloses an online material particle measuring system. The online material particle measuring system comprises an automatic material-fetching device, an automatic shooting device and anauxiliary control device, wherein the automatic material-fetching device is used for seeding material particles in a feed bin into a discharge hopper; the automatic photographing device is used for photographing the material particles in a measurement area; the auxiliary control device comprises a negative pressure generator and a cylinder; the cylinder does work to drive a material-fetching rodto move; the negative pressure generator provides negative pressure to a measuring meter so as to suck the measured material particles into a return bin. Through automatic material fetching and automatic measurement, the online material particle measuring system achieves size measurement of gunpowder particles, can achieve automatic uninterrupted measurement and improves the measurement accuracy and the measurement continuity; the online material particle measuring system changes the conventional physical measurement way, achieves measurement in a light source-based photographing comparison way, can avoid artificial contact with the gunpowder particles and reduces the safety hazards caused by the gunpowder particles; the online material particle measuring system adopts a brand-new measurement way for the gunpowder particles, has the advantages of high precision, high efficiency and the like, and can overcome all defects brought by the current conventional measurement way.

Description

technical field [0001] The invention relates to the field of gunpowder, in particular to an online measurement system for material particles. Background technique [0002] Gunpowder is a substance that can burn or decompose very quickly, and can generate a large amount of heat and gas in a short period of time; under normal circumstances, gunpowder cannot be violently impacted, otherwise it will undergo a rapid chemical reaction, burn and explode. [0003] Granular gunpowder is generally made by extruding powder in a special environment, and the powder is obviously harmful to the human body. Therefore, in the production site, operators need to carry gas masks to work. For the produced particles, random inspection is required to check whether the particles meet the production requirements. The traditional inspection method is to use a small spoon to manually take out a few grains from the production line, and then use a caliper to measure through the logistics measurement me...

Problems solved by technology

[0004] Obviously, the traditional measurement method has great disadvantages. First, the working environment is very harsh, and the environment of gunpowder dust is generally toxic, which will harm the body; second, using a caliper to measure the size will more or less There are collisions and extrusions, which will bring potential safety hazards. At best, this purely manual measurement cannot meet actual needs, especially for automated production lines

At present, no solution has been found for the online measurement of gunpowder
