A transport mesh belt Ⅰ3 is provided between the two transmission shafts Ⅰ2. A drive motor Ⅰ4 is installed on the upper left part of the rear side of the shell 1 by bolt connection. The output shaft of the drive motor Ⅰ4 is connected to the transmission shaft Ⅰ2 on the left side through a coupling. A protective shell 5 is installed on the shell 1. The protective shell 5 is located above the transport mesh belt Ⅰ3. An electric heating component for generating heat to heat fireworks is installed on the protective shell 5. Two transmission shafts Ⅱ15 are rotatably provided on the lower part of the shell 1. A transport mesh belt Ⅱ16 is provided between the two transmission shafts Ⅱ15. The lower left part of the rear side of the shell 1 is connected by bolts. A driving motor II 17 is installed in a manner, and the output shaft of the driving motor II 17 is connected to the transmission shaft II 15 on the left side through a coupling. A support plate 25 is installed on the front side of the shell 1 by bolt connection. A piston cylinder 26 is installed on the support plate 25 by bolt connection. The input end of the piston cylinder 26 is connected and communicated with a one-way tube 28. The input end of the one-way tube 28 is connected to an exhaust pipe 27 that passes through the protective shell 5. Five injection pipes 29 that pass through the shell 1 are connected to the exhaust pipe 27. The injection pipe 29 is located between the transport mesh belt I3 and the transport mesh belt II 16. A piston rod 33 is slidingly arranged in the piston cylinder 26, and a slide groove is provided at the end of the piston rod 33 away from the piston cylinder 26. A connecting shaft 30 is installed on the transmission shaft I 2 on the right side of the shell 1. A rotating disk 31 is fixed to the connecting shaft 30 by a key connection. A sliding rod 32 is fixed to the rotating disk 31, and the sliding rod 32 slides in the slide groove on the piston rod 33.
[0025] See Figure 1-Figure 5 As shown, the electric heating assembly includes an exhaust fan 6, a support shell 7, a heater 8 and a heat pipe 9. Two exhaust fans 6 are installed on the top of the protective shell 5 by bolt connection. The support shell 7 is installed inside the protective shell 5. The heater 8 is installed on the right side of the support shell 7 by bolt connection. The heat pipe 9 is installed inside the protective shell 5 by bolt connection. The output end and input end of the heat pipe 9 are respectively connected to the two heaters 8. The lower part of the support shell 7 is installed with an electric heating network 10 by bolt connection. The electric heating network 10 is made of copper and has good conductivity. Thermal properties: A diffusion bucket 11 is installed at the lower part of the support shell 7 by means of bolt connection, and the electric heating network 10 is located above the diffusion bucket 11. The diffusion bucket 11 is used to concentrate the heat conduction of the hot air flow, so that the heat of the device is concentrated when drying fireworks, thereby reducing heat spillage, improving the efficiency of drying fireworks, and achieving the purpose of energy saving. An isolation curtain 34 is installed on the right side of the protective shell 5 by means of bolt connection, and the lower part of the isolation curtain 34 is in contact with the transport mesh belt Ⅰ3. The isolation curtain 34 is used to isolate the drying area from the outside world to avoid excessive heat loss inside the shell 1 during drying.
[0026] When it is necessary to dry the fireworks, start the heater 8 and the exhaust fan 6, make the heater 8 heat up and conduct the heat through the heat pipe 9, the exhaust fan 6 draws in the air outside the shell 1, heats the air through the heat pipe 9, and then forms a hot air flow that blows on the transport mesh belt Ⅰ3, then start the drive motor Ⅰ4 and the drive motor Ⅱ17, the drive motor Ⅰ4 drives the transport mesh belt Ⅰ3 to rotate through the transmission shaft Ⅰ2, the drive motor Ⅱ17 drives the transport mesh belt Ⅱ16 to rotate through the transmission shaft Ⅱ15, the transmission shaft Ⅰ2 drives the rotating disk 31 to rotate through the connecting shaft 30, and the rotating disk 31 drives the piston rod 33 to move back and forth in the piston cylinder 26 through the sliding rod 32. When the piston rod 33 moves to the right, the air pressure on the left side of the piston cylinder 26 is less than the atmospheric pressure. At this time, the hot air in the protective shell 5 is sucked into the piston cylinder 26 through the exhaust pipe 27 and the one-way pipe 28. When the fireworks are dried, the heater 8 and the exhaust fan 6 are turned off. When the plug rod 33 moves to the left, the air pressure on the left side of the piston cylinder 26 is greater than the atmospheric pressure. Under the action of the one-way tube 28, the hot air is ejected through the jet pipe 29, and then the fireworks are poured onto the transport mesh belt Ⅰ3 through the feed port on the shell 1. When the transport mesh belt Ⅰ3 transports the fireworks to the left, the hot air flow dries the fireworks on the transport mesh belt Ⅰ3. Subsequently, the fireworks fall from the right side of the transport mesh belt Ⅰ3 onto the transport mesh belt Ⅱ16. The transport mesh belt Ⅱ16 transports the fireworks to the right. At this time, a part of the hot air flow blows onto the transport mesh belt Ⅱ16 through the gap of the transport mesh belt Ⅰ3, and the other part of the hot air is ejected through the heat conducting pipe 9, thereby performing secondary drying on the fireworks. At the same time, the excess hot air is utilized through the one-way tube 28 and the jet pipe 29, thereby improving the utilization efficiency of heat and achieving the purpose of energy saving. The dried fireworks fall downward from the right side of the transport mesh belt Ⅱ16.
[0027] Example 2: Based on Example 1, refer to Figure 4 and Figure 5 As shown, it also includes a receiving plate 18, a threaded rod 19, a guide rod 20, a buffer pad 21, a connecting rod 22 and a return spring 23. Two guide rods 20 are slidingly arranged on the upper right side of the shell 1. A threaded rod 19 is threadedly arranged on the upper right side of the shell 1. The threaded rod 19 is located between the two guide rods 20. The threaded rod 19 is located at one end inside the shell 1 and is rotatably provided with a receiving plate 18 fixedly connected to the guide rod 20. The lower part of the receiving plate 18 is inclined toward the transport mesh belt II 16. Four connecting rods 22 are passed through the receiving plate 18. A return spring 23 is arranged between the connecting rod 22 and the receiving plate 18. A buffer pad 21 is commonly fixed on the four connecting rods 22. The buffer pad 21 slides on the receiving plate 18. A telescopic sleeve 24 is sleeved on the connecting rod 22. The telescopic sleeve 24 covers the return spring 23. The telescopic sleeve 24 is used to protect the return spring 23 to prevent foreign matter from getting stuck in the return spring 23.
[0028] By rotating the threaded rod 19, the threaded rod 19 drives the receiving plate 18 to move up and down under the guidance of the guide rod 20, and the receiving plate 18 drives the buffer pad 21 and the return spring 23 to move up and down, thereby adjusting the height of the receiving plate 18 so that the receiving plate 18 is at a suitable height. When the fireworks fall from the right side of the transport mesh belt Ⅰ3, the fireworks first fall on the buffer pad 21, and the buffer pad 21 moves downward, driving the connecting rod 22 to slide downward. The connecting rod 22 stretches the return spring 23 to cause it to deform. Subsequently, the return spring 23 drives the buffer pad 21 to slide upward and restore to its original shape through the connecting rod 22. The fireworks roll down along the buffer pad 21 to above the transport mesh belt Ⅱ16. In this way, the buffer pad 21 cushions the fireworks when they fall, avoiding the fireworks from violent collision when falling downward, thereby improving the safety of the fireworks during drying.
[0029] See Figure 1 、 Figure 3 and Figure 4 As shown, it also includes a collecting frame 12, a handle 13 and an anti-slip cover 14. The collecting frame 12 is slidably arranged in the discharge port at the lower part of the shell 1. The handle 13 is installed on the right side of the collecting frame 12 by bolt connection. The anti-slip cover 14 is provided on the handle 13. The anti-slip cover 14 is made of silicone material, which can make the hand more comfortable when holding the handle 13.
[0030] The dried fireworks fall downward from the right side of the transport mesh belt II 16 into the collection frame 12, which collects the fireworks. After drying, the handle 13 is pulled to the right to remove the collection frame 12 from the inside of the shell 1, and the fireworks in the collection frame 12 are processed and handled.
[0031] The technical principles of the embodiments of the present invention have been described above in conjunction with specific embodiments. These descriptions are intended solely to explain the principles of the embodiments of the present invention and should not be construed in any way as limiting the scope of protection of the embodiments of the present invention. Based on the explanations herein, those skilled in the art will be able to conceive of other specific implementations of the embodiments of the present invention without inventive effort, and these implementations will fall within the scope of protection of the embodiments of the present invention.
