Description

Automatic quantitative powder raw material filling device for filling inner barrel of firework Technical Field The utility model relates to the technical field of firecracker production equipment, in particular to an automatic quantitative powder raw material filling device for inner barrel filling of a firecracker. Background In the field of firework and firecracker production, an inner barrel filling procedure is one of the key links, and the core task is to accurately fill powder raw materials such as an oxidant, a reducing agent and the like into an inner barrel of the firework and firecracker. For a long time, the working procedure mainly depends on manual operation, workers need to directly contact inflammable and explosive powder medicines, the production efficiency is low, the labor intensity is high, and extremely high safety risks exist. The manual operation easily causes uneven drug mixing and fluctuation of the filling quantity, and further aggravates the hidden danger of explosion. Although the industry in recent years starts to introduce automatic equipment to replace manual operation, the prior art still has the remarkable defects that for example, a quantitative material taking device adopting a turntable rotation or end face scraping mode is unreasonable in structural design, drug residues are difficult to thoroughly clean, safety accidents are easy to cause when the equipment is maintained due to residual drug powder, and a translational type quantitative device is seriously leaked due to insufficient sealing property, so that the single machine productivity is difficult to promote. In addition, the existing equipment generally lacks modularized design, and is complex in operation and has potential safety hazards when the quantitative unit is replaced, so that the multi-specification production requirement is difficult to adapt. The problems severely restrict the automatic process of firecracker production, and a filling device with accurate quantification, high efficiency, safety, easy maintenance and strong suitability is needed. Disclosure of utility model In order to solve the above problems in the prior art, the present utility model provides an automatic quantitative powder raw material filling device for filling an inner barrel of a firework, which is used for solving the above technical problems. In order to achieve the above purpose, according to the present utility model, an automatic quantitative powder raw material filling device for filling an inner barrel of a firework is provided, which comprises a frame, a turntable device, a bin, a quantitative plate device, a needle punching device and a turntable positioning device, wherein the turntable device, the bin and the needle punching device are arranged on the frame, a plurality of mounting stations of the quantitative plate device are arranged on the turntable device, the quantitative plate device comprises a quantitative plate, a valve plate, a quantitative bottom plate and a quantitative plate opening and closing device, a plurality of quantitative holes are arranged on the quantitative plate, through holes are correspondingly arranged on the valve plate, the quantitative plate opening and closing device controls the through holes and the quantitative holes to be aligned or misplaced, and the raw materials are punched out of the quantitative plate through the needle punching device. Through the collaborative work of integrated carousel device, quantitative board opening and shutting device and towards needle device, realize the automatic ration of powder raw materials and load, reduce manual intervention, promote and load efficiency and security, the modular quantitative board design supports quick replacement, adaptation different production specifications. In some specific embodiments, the cartridge comprises two separate sets of a bin, a feed divider and a level sensor, the feed divider and level sensor controlling the continuous feeding of elemental medicament. The double-bin design combines a distributing mechanism and a material level sensor, ensures continuous feeding of simple substance medicaments, avoids mixed medicament storage risks, and improves feeding stability and automation level. In some specific embodiments, a sealing strip is arranged at the bottom of the bin, and the sealing strip is in rotary sealing with the turntable device. The sealing strip and the turntable device are in rotary sealing, so that the leakage of medicinal powder is effectively prevented, the tightness of equipment is enhanced, the risk of dust explosion is reduced, and a water washing cleaning flow is supported. In some specific embodiments, the turntable device is further provided with a detachable material cleaning port. The arrangement of the detachable material cleaning opening simplifies the residual medicine cleaning flow, reduces the downtime and reduces the potential safety hazard in the maintenance process.
