Quantitative explosive feeding device

Abstract

The invention discloses a quantitative explosive feeding device which comprises a constant volume tube (2), an upper gate disc (7), a lower grate disc (9) and a uniform explosive distribution tube (1), wherein the upper gate disc (7) which is used for opening or closing the upper end of the constant volume tube is arranged between the upper end of the constant volume tube (2) and a hopper (5), the lower gate disc (9) which is used for closing or opening the lower end of the constant volume tube is arranged at the lower end of the constant volume tube, the uniform explosive distribution tube (1) is arranged below the lower gate disc, an orifice at the upper end of the uniform explosive distribution tube corresponds to an orifice at the lower end of the constant volume tube, and an orifice at the lower end of the uniform explosive distribution tube corresponds to a paper tube. The quantitative explosive feeding device has the beneficial effects of uniform explosive distribution, accurate quantification, quick blanking and directional feeding, also has capabilities of avoiding explosive scattering, causing small explosive waste, improving explosive feeding efficiency and lowering production cost of firecrackers and fireworks, and is beneficial to environmental protection. The quantitative explosive feeding device has the advantages of compact structure and convenience for production and maintenance, and is applicable to massive explosive feeding of various types of firecracker and firework paper tubes with different sizes; and in addition, since the explosive feeding operation is carried out in a closed environment, the production is safe and has high reliability.

Description

technical field [0001] The invention relates to a medicinal material sub-charging device, in particular to a medicinal material quantitative feeding device for the production of firecrackers and fireworks. Background technique [0002] Quantitative charging of medicinal materials is an important process in the manufacture of firecrackers and fireworks. The quality of the charge directly affects the quality of firecrackers and fireworks, and the efficiency of the charge directly affects the manufacturing cost of firecrackers and fireworks. At present, except for some small family workshop-style firecrackers and fireworks that still use manual charging, most of the firecrackers and fireworks processing enterprises use mechanical devices to directly load the ingredients into the Firecrackers and fireworks are filled in each paper tube to complete the charge. However, the existing drug charging device still has the following problems during use: one is that the existing drug ...

AI Technical Summary

Problems solved by technology

However, the existing drug charging device still has the following problems during use: one is that the existing drug charging machine uses open flood irrigation to sprinkle the drug material on the cake, the amount of drug material spilled is large, the spilled surface is large, and the drug material is wasted. It not only increases the cost, but also causes great pollution to the working environment; the second is that the existing drug filling machine adopts centralized feeding, and the drug material poured on the cake is swept into the paper tube with a brush or a scraper to complete the charging. The charging device does not have the ability to evenly distribute the medicine before loading, so not only the weight of the medicine in the paper tube is uneven, which affects the performance of the fireworks and firecrackers, but also more surplus medicine needs to wait for recycling, which increases the cost and causes waste , will bring security risks
