Gunpowder weighing device with re-weighing function

Abstract

The invention discloses a gunpowder weighing device with a re-weighing function. The device comprises a supporting device which is provided with aprimary weighing area and a secondary weighing area, adischarging device, a conveying device and a static electricity eliminating device, wherein the discharging device is used for adding gunpowder; the conveying device is provided with a gunpowder cup, the gunpowder cup is used for receiving the gunpowder discharged by the discharging device in the primary weighing area, and the conveying device drives the gunpowder cup to be transferred to the secondary weighing area from the primary weighing area so as to weigh the gunpowder cup loaded with the gunpowder for multiple times; and the static electricity eliminating device is used for eliminating static electricity of the gunpowder in the gunpowder cup which is subjected to primary weighing and / or secondary weighing. The influence of static electricity on gunpowder weighing can be reduced, the gunpowder weighing accuracy is improved, and the device is applied to the field of gunpowder and explosive weighing equipment.

Description

technical field [0001] The invention relates to the field of weighing equipment for explosives, in particular to a weighing device for gunpowder with a reweighing function. Background technique [0002] Gunpowder is in powder form, and during its transportation and production process, it is easy to rub against other equipment to generate static electricity, making gunpowder charged with static electricity. For example, in the gunpowder weighing process, automatic gunpowder weighing devices are often used to weigh gunpowder, but during weighing, the gunpowder will rub against the contact part of the weighing device, and the contact part can be the part of the feed hopper. The bucket wall, the tube wall of the transmission pipeline, etc., the gunpowder rubs against the bucket wall or the tube wall during the transmission process, and then generates static electricity, so that the gunpowder is charged with static electricity when weighing. [0003] Gunpowder has high precision...

AI Technical Summary

Problems solved by technology

[0003] Gunpowder has a high accuracy in weighing, which needs to reach milligrams, but when the weighing machine is affected by static electricity, its weighing accuracy will change, which will eventually lead to inaccurate measurement results and affect the weighing results of gunpowder.

And after weighing the gunpowder many times, the weighing machine that weighs the gunpowder may malfunction, causing its accuracy to change, and finally get the defective product that the weighing result shows has reached the standard but actually did not meet the standard. When a fault occurs, it is difficult for the staff of the production line to detect it directly, resulting in the production line always producing defective products, which seriously affects the production quality
