[0017] Preferably, when the roller 4 deviates from the roller shaft 401 and faces downward, the distance between the roller 4 and the conveying belt assembly 2 is just right to touch the fireworks boxes, when the roller 4 approaches the roller shaft 401 and faces downward, the distance between the roller 4 and the conveying belt assembly 2 is greater than the fireworks boxes, at this time, the plastic on the surface of the fireworks boxes cannot be thermoplastic, the roller 4 is provided with an existing electric heating wire assembly and a matched power supply to heat the surface of the roller 4.

[0018] Preferably, the cooling device comprises a refrigerator 3, an upper plate 101 fixedly installed on the upper portion of the frame 1, the refrigerator 3 is placed on the upper plate 101, and the output end of the refrigerator 3 is communicated with a plurality of conveying plates 301 internally provided with hollows.

One end of the L-shaped rod 306 abuts against the upper surface of the roller 4. Only when the roller 4 near the roller shaft 401 faces upward, the surface of the roller 4 abuts against the L-shaped rod 306. At this time, the light emitted by the inductive element 304 will not be blocked. When the roller 4 near the roller shaft 401 faces upward, the surface of the roller 4 abuts against the L-shaped rod 306.
