[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-4 As shown, a fireworks tube cutter includes a cutting table 1 and a movable cavity 11 thereon. Two sets of support frames are symmetrically arranged within the movable cavity 11, and each support frame includes support rods 12 arranged parallel and symmetrically along the delivery direction of the cutting table 1. A lead screw 21 is axially rotatably mounted within the movable cavity 11, and a pusher 22 slidably mounted within the movable cavity 11 rotates threadedly with the lead screw 21. A crossbar 23 fixedly mounted on the pusher 22 is located at one end of a fireworks tube 3 mounted on the support rod 12. A cutting machine 7 is movably mounted vertically within the cutting table 1, and a circular saw blade 71 mounted on the cutting machine 7 is simultaneously movably mounted on both fireworks tubes 3. By placing the two fireworks tubes 3 on the support rods 12 of the support frames, and then rotating the lead screw 21 to move the pusher 22 and push the two fireworks tubes 3 closer to the cutting machine 7, and then moving the cutting machine 7 downwards to allow the circular saw blade 71 to simultaneously cut the two fireworks tubes 3, synchronous cutting of the two fireworks tubes 3 is achieved, thereby improving work efficiency.

[0026] Specifically, an auxiliary motor 2 is fixedly installed on the cutting table 1, and the output end of the auxiliary motor 2 is fixedly installed on one end of the lead screw 21, so that the lead screw 21 can be rotated through the auxiliary motor 2.

[0027] As a further technical solution provided by this utility model, an installation platform 4 is provided inside the movable cavity 11, and a main motor 41 is fixedly installed on the installation platform 4. The drive wheel 42 fixedly installed at the output end of the main motor 41 is simultaneously movably arranged on the outer wall of the two firework tubes 3.

[0028] Specifically, such as Figure 4 As shown, the main motor 41 drives the drive wheel 42 to rotate. The drive wheel 42 simultaneously adheres to the outer wall of the two firework tubes 3, thereby driving the two firework tubes 3 to rotate. This, combined with the cutting of the circular saw blade 71, achieves the cutting and segmentation of the firework tubes 3.

[0029] Furthermore, a mounting bracket 5 is slidably installed in the cutting table 1 along the vertical direction, and the output end of the electric push rod 6 fixedly installed in the cutting table 1 is fixedly installed on the mounting bracket 5, and the cutting machine 7 is fixedly installed on the mounting bracket 5.

[0030] Specifically, by using the electric push rod 6 to drive the mounting bracket 5 to move down, and cooperating with the drive wheel 42 to rotate so that the circular saw blade 71 can make cuts, while raising the circular saw blade 71 and moving the firework tube 3, and then driving the circular saw blade 71 down again, continuous cutting operations can be achieved.

[0031] Furthermore, a shield 24 is fixedly installed on the crossbar 23, and the shield 24 is respectively placed over the ends of the two firework tubes 3.

[0032] Specifically, by using the shielding cover 24 to simultaneously shield the ends of the two firework tubes 3, the stability of the firework tubes 3 when moving is improved.

[0033] Furthermore, the slide rod 43, which is fixedly installed on the mounting platform 4, is slidably mounted on the cutting table 1.

[0034] Specifically, the sliding rod 43 drives the main motor 41 to move up and down, thereby causing the drive wheel 42 to detach from the outer wall of the firework tube 3 when the firework tube 3 moves, thus improving the stability of the firework tube 3 when it moves.

[0035] Furthermore, the mounting bracket 5 is provided with a first toothed opening 53, and the slide rod 43 is provided with a second toothed opening 44. The first toothed opening 53 and the second toothed opening 44 respectively mesh with the main gear 8 rotatably disposed inside the cutting table 1.

[0036] Specifically, the mounting bracket 5 is lowered by the electric push rod 6, at which point the circular saw blade 71 approaches the fireworks tube 3, and simultaneously... Figure 4 As shown, the mounting bracket 5 moves down to engage the first toothed jaw 53 with the main gear 8. Then, the main gear 8 rotates and engages with the second toothed jaw 44 to move the slide rod 43 up. The slide rod 43 then moves up to drive the drive wheel 42 on the main motor 41 to fit against the outer wall of the firework tube 3, so that the drive wheel 42 drives the firework tube 3 to rotate while the circular saw blade 71 cuts. Then, when the mounting bracket 5 moves up, it engages the first toothed jaw 53, the second toothed jaw 44 and the main gear 8 again to move the drive wheel 42 down and disengage from the outer wall of the firework tube 3, so that the firework tube 3 can move and advance in the future.

[0037] Furthermore, pressure rollers 52 are symmetrically arranged on the mounting frame 5, and the pressure rollers 52 are movably mounted on the outer wall of the firework tube 3.

[0038] Specifically, when the mounting frame 5 moves down, the drive wheel 42 moves up and fits against the outer wall of the firework tube 3. The pressure wheels 52 symmetrically arranged on the mounting frame 5 fit against the outer wall of the firework tube 3, thereby making the firework tube 3 more stable when rotating.

[0039] Furthermore, the pressure roller 52 is slidably mounted on the mounting bracket 5, and a main spring 51 is fixedly installed between the pressure roller 52 and the mounting bracket 5.

[0040] Specifically, when the mounting bracket 5 moves upward to move the circular saw blade 71 away from the fireworks tube 3, the main spring 51 pushes the pressure roller 52 to continuously adhere to the outer wall of the fireworks tube 3, thereby preventing the circular saw blade 71 from moving upward and causing the fireworks tube 3 to deviate, thus improving the stability of the fireworks tube 3.

[0041] Furthermore, the drive wheel 42 is a rubber wheel.

[0042] Specifically, rubber wheels are used to increase friction, making it easier for the drive wheel 42 to better rotate the firework tube 3.

[0043] Furthermore, mounting bracket 5 is made of stainless steel.

[0044] Working principle: The electric push rod 6 drives the mounting frame 5 to move downwards. At this time, the circular saw blade 71 approaches the fireworks tube 3, and then the pressure roller 52 first adheres to the outer wall of the fireworks tube 3. As the mounting frame 5 continues to move downwards, the main spring 51 stores force. Figure 4 As shown, the mounting bracket 5 moves downward to engage the first toothed jaw 53 with the main gear 8. Then, the main gear 8 rotates and engages with the second toothed jaw 44 to move the slide rod 43 upward. The upward movement of the slide rod 43 drives the drive wheel 42 on the main motor 41 to contact the outer wall of the firework tube 3, so that the drive wheel 42 drives the firework tube 3 to rotate while the circular saw blade 71 cuts. Then, when the mounting bracket 5 moves upward, it again engages the first toothed jaw 53, the second toothed jaw 44, and the main gear 8 to move the drive wheel 42 downward and disengage it from the outer wall of the firework tube 3, so that the firework tube 3 can move and advance subsequently. At the same time, the main spring 51 releases its stored force to push the pressure wheel 52 to continue to contact the outer wall of the firework tube 3, thereby preventing the firework tube 3 from moving upward and deviating when the circular saw blade 71 moves upward, thus improving the stability of the firework tube 3.

[0045] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
