Description

Technical Field

[0001] This utility model belongs to the technical field of pyrotechnic agent transfer devices, specifically a pyrotechnic agent feeding and turning device. Background Technology

[0002] Fireworks propellants mainly refer to the gunpowder filling the inside of fireworks. Gunpowder is further divided into many types during fireworks manufacturing, such as the opening explosive used to detonate the fireworks, the effect explosives that produce various effects, and the fuse explosives used to prepare the fuse. Modern fireworks production has introduced many new pieces of equipment. For example, a fireworks loading machine is needed to fill the inner tube of the fireworks with gunpowder. During the operation of this equipment, a third-party organization or personnel is required to transport the gunpowder into the loading machine. However, existing gunpowder conveying equipment generally uses vacuum suction or pneumatic conveying. For high-risk gunpowder, manual conveying is usually required, lifting the gunpowder to the loading machine hopper and then pouring it into the hopper. If pneumatic conveying is used, the highly dangerous and explosive nature of the gunpowder could lead to an explosion with serious consequences. Furthermore, manual conveying of fireworks propellants poses safety risks to operators due to the highly dangerous and explosive nature of the gunpowder, and also incurs significant labor costs. Utility Model Content

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A pyrotechnic agent feeding and turning device, comprising

[0006] A lifting mechanism is mounted on a base and has a flipping mechanism. The lifting mechanism is used to lift the storage mechanism containing the pyrotechnic agent. The flipping mechanism has a storage mechanism at its drive end and is used to flip the storage mechanism to pour out the pyrotechnic agent inside.

[0007] As a further improvement to the above technical solution, the lifting mechanism is vertically installed on the base, the lifting mechanism includes a lifting drive component, the lifting drive component is provided with a mounting seat that can move up and down, and the flipping mechanism is installed on the mounting seat.

[0008] As a further improvement to the above technical solution, the flipping mechanism includes a flipping drive component and a rotating shaft, one end of which is fixedly connected to a storage mechanism; the flipping mechanism also includes a sliding plate, the rotating shaft is rotatably mounted on the sliding plate, the flipping drive component is fixedly mounted on the sliding plate, and the flipping drive component is used to drive the rotating shaft to rotate.

[0009] As a further improvement to the above technical solution, the rotating shaft is fixedly connected to the slide plate via a bushing, and the bushing is fixedly connected to the mounting base or the slide plate is fixedly connected to the mounting base.

[0010] As a further improvement to the above technical solution, the storage mechanism includes a storage device and a guide plate, wherein the storage device is designed to be open at one end.

[0011] As a further improvement to the above technical solution, the storage device and the guide plate are designed separately. The bottom of the guide plate is provided with a placement seat for placing the storage device. The guide plate is fixedly connected to the rotating end of the flipping mechanism.

[0012] As a further improvement to the above technical solution, a fixing belt for fixing the storage device is provided on the side of the guide plate, and a limit card is provided on the inner side wall of the guide plate. The limit card is used to restrict the lateral and longitudinal movement of the storage device.

[0013] As a further improvement to the above technical solution, the lifting drive component includes an active synchronous pulley, a passive synchronous pulley, and a synchronous belt. The active synchronous pulley is disposed inside the base and is connected to the output shaft of the drive mechanism. The passive synchronous pulley is located above the lifting mechanism. A synchronous belt is disposed between the active synchronous pulley and the passive synchronous pulley, and the mounting base is fixedly disposed on the synchronous belt.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: the lifting mechanism combined with the tilting mechanism can lift and unload the drug-filled loading device. Due to the presence of the guide plate, the drug will not collide violently with the side wall of the feeding device during the unloading process, thereby reducing the possibility of the pyrotechnic agent being ignited by the collision with the inner wall of the feeding device, and improving the safety of the entire lifting device; at the same time, it reduces the step of manually lifting the drug, reducing the labor intensity of personnel.
