Problems solved by technology

[0002] The powder charging process is an important process in the production of firecrackers. The quality of the powder directly affects the quality of the firecrackers. The efficiency of the powder directly affects the manufacturing cost of firecrackers. The degree of automation of the powder also seriously affects the safety of the production process.
At present, the firecracker industry is in the process of transforming from traditional manual charging to mechanical automatic charging, but the existing charging machinery has many safety hazards, unstable production quality, large pollution of the working environment, large waste of raw materials, and difficult operation problems, etc., need to be resolved urgently

Embodiment 1

[0023] Embodiment 1: Referring to the accompanying drawings, reflecting a specific structure of the present invention, the safety type firecrackers and medicine charge equipment include a feeding mechanism 1, a screening mechanism 2, a mixing mechanism 3 and a filling mechanism connected in sequence by a conveyor belt 4. The mixing mechanism 3 and the filling mechanism 4 are separated by an explosion-proof wall into an independent charging room. A conveyor belt passage port is provided on the explosion-proof wall, and a fire-fighting water tank 5 is provided at the conveyor belt passage port. Shaped bottom 501, the fire-fighting water that device fills in the film bag in fire-fighting water tank 5; There is at least one aluminum roller on each conveyor belt; the ground is covered with anti-static mats, and the equipment is equipped with a grounding device.

[0024] The feeding structure includes three feeding hoppers 101. The feeding hoppers 101 are made of all-copper material...

Embodiment 2

[0032] Embodiment 2: The difference from Embodiment 1 is only that the shape of the stirring blades is different, and a number of "8"-shaped stirring blades 802 are fixed on the inner wall of the mixing tube 801. The "8"-shaped stirring blades 802 The middle part is the smallest, and gradually enlarges from the middle part to both ends. One enlarged end is fixed on the inner cavity wall of the mixing cartridge 801, and the other end has an arc-shaped end. Repeated practice has proved that the "8"-shaped stirring blade 802 and the copper screen 803 prevent the generation of static electricity, and at the same time have a high mixing efficiency on the basis of ensuring safety. It can process about 2,000 firecracker tube cakes per hour.

Abstract

The invention discloses safety firecracker gunpowder mixing and filling equipment which comprises an adding mechanism, a screening mechanism, a mixing mechanism and a filling mechanism which are connected in sequence through a conveyor belt. By means of the equipment, all work of preparation, mixing, filling, automatic residual gunpowder recovery and firecracker cake conveying can be finished on a spot in time, and the amount of gunpowder stored in the equipment is controlled within a relative safe range through dynamic control over the gunpowder amount; static and electrical sparks are comprehensively and completely eradicated through various measures; the equipment has the operating worker safe distance protection function, and a blast wall is arranged for isolation, so that personnel safety accidents are avoided to the maximum extent; the operating safety performance of the equipment is ensured, and a safety coefficient of the equipment is largely increased. Meanwhile, the safety firecracker gunpowder mixing and filling equipment further has the advantages that production efficiency is improved, gunpowder waste is reduced, operating difficulty is decreased, and the service life is prolonged.
