Technical Field
[0001] This utility model relates to the field of fireworks shell production technology, specifically to a waste recycling device for fireworks shell processing and production. Background Technology
[0002] Firework shells are a type of firework, nearly spherical in shape, launched from a special tube, and bursting into the air to create various colors, patterns, or other effects. Large-scale performances generally use fireworks shells along with ground-based fireworks and smaller fireworks, but fireworks shells are the primary element for enhancing the spectacle. The outer shell of a fireworks shell typically consists of two hemispherical parts.
[0003] Fireworks typically contain materials such as gunpowder, metal powder, plastic, and paper. During processing, there may be unused raw materials, defective products, packaging materials, and other waste. Some of this waste is piled up together. Among these, the waste gunpowder is highly hazardous and needs to be separated from large debris such as packaging materials. Furthermore, the waste gunpowder needs to be mixed with a sodium carbonate solution. This paper proposes a device that can separate the waste gunpowder from large debris and facilitate the mixing of the waste gunpowder with the sodium carbonate solution. Utility Model Content

Detailed Implementation
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-4 As shown, a waste recycling device for the production of fireworks shells includes a workbench 1, with baffle plates 2 fixed on both sides of the surface of the workbench 1. A first conveyor belt 3 for feeding is provided on one side of the surface of the workbench 1, and a second conveyor belt 6 for discharging is provided on the other side of the surface of the workbench 1. An action plate 4 is rotatably provided on the surface of the baffle plate 2, and a grid 5 is fixed on the surface of the action plate 4. A mixing tank 7 is fixed on the surface of the workbench 1, and a mixing mechanism 8 is provided in the inner cavity of the workbench 1. A vibration mechanism 9 for striking the action plate 4 is provided on the surface of the mixing mechanism 8.
[0020] In use, this utility model can transport waste materials under the action of the first conveyor belt 3. Then, under the action of the stirring mechanism 8 and the vibration mechanism 9, the action plate 4 drives the grid 5 to vibrate, so that the waste medicine falls from the grid 5, achieving the effect of separating waste medicine from large debris. Then, under the action of the stirring mechanism 8, the waste medicine and sodium carbonate solution in the stirring tank 7 are stirred and mixed, improving the mixing efficiency of waste medicine and sodium carbonate solution and improving the practicality of this device.
[0021] The stirring mechanism 8 includes a motor 81 fixed to the inner cavity of the workbench 1. The output shaft of the motor 81 is fixed with a main rod 82, and a plurality of stirring rods 83 are fixed on the surface of the main rod 82. In this embodiment, through the arrangement of the motor 81, the main rod 82 and the stirring rods 83, the main rod 82 is rotated under the action of the motor 81, and then the liquid in the inner cavity of the stirring tank 7 can be stirred under the action of the stirring rods 83, thereby improving the mixing capacity of sodium carbonate solution and waste medicine.
[0022] The vibration mechanism 9 includes a first transmission rod 91 driven by a bevel gear to the output shaft of the motor 81. A second transmission rod 92 is connected to the other end of the first transmission rod 91 via a bevel gear. A third transmission rod 93 is connected to the other end of the second transmission rod 92 via a bevel gear. A rotating rod 94 is connected to the other end of the third transmission rod 93 via a bevel gear. Several striking blocks 95 are fixed to the surface of the rotating rod 94. One end of the actuating plate 4 is in contact with the striking blocks 95. In this embodiment, through the arrangement of the first transmission rod 91, second transmission rod 92, third transmission rod 93, rotating rod 94, and striking blocks 95, when the motor 81 is working, the first transmission rod 91 rotates under the action of the motor 81, thereby causing the second transmission rod 92 and third transmission rod 93 to work. Under the action of the bevel gear, the rotating rod 94 drives the striking blocks 95 to work, thereby causing the actuating plate 4 to vibrate under the action of the striking blocks 95.
[0023] Bearing seats 11 are rotatably provided on both sides of the surface of the third transmission rod 93. The other end of the bearing seat 11 is fixed to the surface of the worktable 1. In this embodiment, the bearing seat 11 provides a limit for the operation of the third transmission rod 93 and improves the stability of the third transmission rod 93 when it rotates.
[0024] The surface of the workbench 1 is fixed with a feeding shell 10. The feeding shell 10 is hollow with a circular shape at the top and bottom. When it is used with the grid 5 at the top, it is used with the mixing tank 7 at the bottom. In this embodiment, by setting the feeding shell 10, after the waste medicine falls down due to the vibration of the grid 5, the waste medicine can be assisted by the feeding shell 10 to fall into the mixing tank 7.
[0025] The height of the baffle plate 2 is greater than the horizontal plane where the grid 5 is located. In this embodiment, this setting can prevent waste medicine and waste paper from leaving the working area when the grid 5 is vibrating, thus improving the practicality of the device.
[0026] Working principle: In operation, the operator first places the sodium carbonate solution in the mixing tank 7, then uses the stirring mechanism 8. Under the action of the motor 81, the main rod 82 drives the stirring rod 83 to rotate, thereby stirring the sodium carbonate solution in the mixing tank 7. At this time, the operator can use the first conveyor belt 3 to transport the waste fireworks to the surface of the grid 5. Then, under the action of the motor 81, the first transmission rod 91, the second transmission rod 92, the third transmission rod 93 and the rotating rod 94 work. Under the action of the striking block 95, the action plate 4 drives the grid 5 to vibrate, thereby causing the waste material to vibrate. Under the action of vibration, the waste medicine and large debris in the waste material are separated. Then, under the action of the grid 5 and the feeding shell 10, the waste medicine enters the mixing tank 7. Under the action of stirring, the waste medicine and sodium carbonate solution are mixed. Large debris, under the action of the tilting action of the grid 5 and the action plate 4, falls onto the surface of the second conveyor belt 6, thus participating in the next process.
