[0002] The origin of firecrackers has a history of more than 1,000 years. When there was no gunpowder and paper, ancient people burned bamboo with fire to make it explode and make sounds to drive away the plague god. Existing firecrackers require a mixing device to mix the gunpowder inside the firecrackers during production.

[0003] For example, Chinese patent publication number CN216605023U, "A Raw Material Mixing Device for Firecracker Production," discloses a raw material mixing device for firecracker production, including a mixing barrel and a stirring assembly. The mixing barrel includes a barrel body with a top through-hole arrangement, a hole ring fixed horizontally on the upper side of the barrel body, a filter cylinder vertically inserted into the hole ring, a vibration motor fixed vertically on the outer circumference of the barrel body, a stirring assembly vertically inserted into the barrel body, and a stirring assembly including a stirring cover and a stirring shaft. A feeding port is vertically penetrated on the top surface of the stirring cover, the stirring cover is detachably connected to the open end of the barrel body, a motor is fixed on the top surface of the stirring cover, the output end of the motor is connected to the end of the stirring shaft, a stirring shaft is vertically rotatably connected to the stirring cover, and the stirring shaft vertically penetrates the filter cylinder and is inserted into the barrel body. This utility model can ensure the safety of the gunpowder inside the firecrackers when it is mixed.

[0004] However, in actual use, it is inconvenient to crush overly large raw materials. The crushing plate is driven to rotate by the stirring shaft, so that it cooperates with the filter cylinder to crush the raw materials. However, the crushing plate will push the raw materials to slide on the filter cylinder when rotating, and the crushing efficiency is low, which is not convenient for achieving a more efficient crushing effect.
