The left part of the second guide frame 61 is rotatably connected to the baffle 65, and a torsion spring 651 is connected between the baffle 65 and the second guide frame 61.

[0038] The scraping mechanism 6 of the present device can be used to scrape the waterproofing agent flat. When the spraying frame 54 moves to the right, it drives the sliding frame 63 to move to the right. At this time, the sliding frame 63 moves upward along the second guide frame 61, and the second pressure spring 621 is squeezed and contracted.

At this time, the sliding frame (63) moves upward along the second guide frame (61), and the second pressure spring (621) is squeezed and contracted. At this time, the scraper (64) does not contact the paper tube (0). When the spraying frame (54) moves to the right and moves to the left to reset after spraying the paper tube (0), the second pressure spring (621) rebounds, so that the sliding frame (63) moves downward and contacts the second guide frame (61). At this time, the scraper (64) contacts the paper tube (0) and moves to the left on the paper tube (0).

6. A waterproof treatment device for the outer side of a firework paper tube according to claim 5, characterized in that: The scrapers (64) are all arc-shaped.

7. A waterproof treatment device for the outer side of a firework paper tube according to claim 5, characterized in that: The auxiliary mechanism (7) also includes a support member (71), a second electric push rod (72) and a connecting member (73). The upper side of the first fixed frame (41) is connected to the support member (71), the upper side of the support member (71) is connected to the second electric push rod (72), the telescopic end of the second electric push rod (72) is connected to the connecting member (73), and the connecting member (73) is rotatably connected to the slider (45). When the slider (45) needs to be pulled to move, the second electric push rod (72) on the support member (71) is started to push the connecting member (73) to move, so that the connecting member (73) drives the slider (45) to move.

8. A waterproof treatment device for the outer side of a firework paper tube according to claim 7, characterized in that: The paper tube (0) further comprises a collecting mechanism (8), the collecting mechanism (8) comprising a collecting frame (81), a connecting pipe (82), a connecting valve (83) and a water pump (84). The upper side of the base (1) is connected to the collecting frame (81), the rear side of the collecting frame (81) is connected to the water pump (84), the rear side of the water pump (84) is connected to the connecting pipe (82), a connecting valve (83) is connected between the connecting pipe (82) and the feeding pipe (55), the waterproofing agent flows from the paper tube (0) and enters the collecting frame (81), the waterproofing agent delivery pipe is connected to the connecting valve (83), and the waterproofing agent is sent into the feeding pipe (55) through the connecting valve (83), when the waterproofing agent in the collecting frame (81) needs to be recovered and used, the connecting valve (83) is adjusted to communicate with the connecting pipe (82), and the water pump (84) is started to send the waterproofing agent in the collecting frame (81) into the feeding pipe (55).

9. A waterproof treatment device for the outer side of a firework paper tube according to claim 8, characterized in that: The connecting pipe (82) is retractable.

10. A waterproof treatment device for the outer side of a firework paper tube according to claim 8, characterized in that: The paper tube (0) further comprises a drying mechanism (9), the drying mechanism (9) comprising a fixing member (91) and a drying lamp (92), the fixing member (91) being connected to the front side of the support frame (2), the front side of the fixing member (91) being connected to the drying lamp (92), and when the waterproofing agent is sprayed on the paper tube (0), the drying lamp (92) on the fixing member (91) is lit.
