Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0018] Refer to Figures 1 to 4, A device for recycling the remaining charge in the production of fireworks and firecrackers, including a collection device 10. The collection device 10 is fixed at one end of the conveyor through a support rod. The collection device 10 includes a collection frame 11 provided at one end of the conveyor. A collection pipe 12 is provided at the bottom of the collection frame 11. A blower 13 is provided at the right end of the collection pipe 12, and the blower 13 is used to prevent blockage. A transport device 20 is provided at the left end of the collection pipe 12. The transport device 20 includes a roller 21. A limiting inclined plate 22 is provided on the right side of the roller 21. A feed inlet 23 is also provided on the right side of the roller 21. A support circular plate 24 is provided on the left side of the roller 21. A motor 25 is fixedly connected to the left side of the support circular plate 24. A discharge groove 26 is provided in the inner wall of the roller 21. A number of discharge plates 27 are provided in the discharge groove 26. The conveyor sends the excess powder to the collection device 10. The powder falls into the collection pipe 12 through the collection frame 11. Under the blowing of the blower 13, the powder passes through the collection pipe 12 and the feed inlet 23 and enters the discharge groove 26 below the roller 21. Then, through the rotation of the roller 21, the discharge groove 26 is rotated above the roller 21, so that the powder is transported to a position higher than the charging machine. The roller 21 rotates continuously, and the remaining materials are continuously collected and utilized without manual handling. The charging machine does not need to stop waiting for the collection of the remaining materials, which is very convenient.

[0019] Preferably, the collection frame 11 is inclined. The left end of the collection frame 11 is located at a position slightly below the middle of the roller 21. The port of the collection pipe 12 is located above the feed inlet 23. The powder passes through the collection pipe 12 and the feed inlet 23 and will fall into the discharge groove 26 below the roller 21.

[0020] Preferably, the limiting inclined plate 22 is provided around the feed inlet 23, and the limiting inclined plate 22 is provided below the collection pipe 12. The limiting inclined plate 22 can prevent the powder from spilling when entering the discharge groove 26.

[0021] Preferably, the discharge plates 27 are evenly arranged in a ring in the discharge groove 26, and the discharge plates 27 are composed of an inclined plate 271 and a vertical plate 272. When the powder enters, it will enter the lowest part of the discharge groove 26 along the inclined plate 271. The powder is always supported by the inclined plate 271 and the vertical plate 272 inclined upward and does not fall until the roller rotates to a certain angle and the inclined plate 271 inclines downward. Please refer to Figure 4 , and when the inclined plate 271 is above the conveying frame 31, the powder will fall into the conveying frame 31.

[0022] Preferably, a conveying device 30 is provided at the middle and upper part of the roller 21. The conveying device 30 is fixed on the conveyor. The conveying device 30 includes a conveying frame 31. One end of the conveying frame 31 is located directly below the top of the discharge groove 26. The other end of the discharge groove 26 is located above the charging machine. A conveying port 32 is provided at the other end of the discharge groove 26. The conveying frame 31 is inclined. After the powder falls into the conveying frame 31, it falls into the charging machine through the conveying port 32 for recycling the powder.

[0023] Preferably, a support slide plate 40 is provided at the bottom of the roller 21. A chute 41 is formed on the support slide plate 40. The roller 21 is rotatably arranged in the chute 41. The support slide plate 40 can limit the position of the roller 21 and prevent the roller 21 from shaking.

[0024] In the present utility model, during use, the conveyor sends the redundant powder to the collection device 10. The powder falls into the collection pipe 12 through the collection frame 11. Under the blowing of the fan 13, the powder passes through the collection pipe 12 and the feed inlet 23 and enters the material discharging groove 26 of the roller 21. When the powder enters, it will enter the lowest part along the inclined plate 271. The roller 21 is driven by the motor 25 to rotate. As the roller 21 rotates, the powder is continuously supported by the inclined upward inclined plate 271 and the vertical plate 272 and does not fall. Until the roller rotates to a certain angle, the inclined plate 271 inclines downward and is above the conveying frame 31, then the powder falls into the conveying frame 31, and then through the inclined conveying frame 31, passes through the conveying port 32 and enters the charging machine.

[0025] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
