[0028] Embodiment one

[0029] Please refer to Figures 1-4 The present application provides a technical scheme: a fireworks shell production device, including base 1 and rotating plate 2, rotating plate 2 is placed above base 1, and rotating plate 2 is rotatably fixed above base 1 through rotating shaft 12, in use, rotating plate 2 can rotate above base 1 around rotating shaft 12, and then it is more convenient to carry out the pasting and fixing operation of fireworks cylinder, the bottom four corners of base 1 are fixed with non-slip pad 11, non-slip pad 11 is provided with at least four, base 1 is stably supported on the desktop through non-slip pad 11, and has the effect of anti-skid placement.

[0030] A limiting block 3 is also provided. There are multiple sets of limiting blocks 3, and each set has a different size. The bottom of each set of limiting blocks 3 is vertically provided with a screw 33 of the same size. The surface of the base 1 is uniformly provided with screw holes 21 that match the screw 33. When it is necessary to assemble and paste the firework tube, the appropriate size and number of limiting blocks 3 can be selected according to the finished firework shell. The limiting blocks 3 are locked on the surface of the rotating plate 2 by screwing the screw 33 below into the appropriate screw holes 21. Then, glue can be applied to the outer ring of a single firework tube, and the open end can be aligned with the limiting block 3 and inserted downwards to achieve quick positioning of the single firework tube. Then, glue can be used to fix it, and packaging paper can be put on it for fixation. Since the rotating plate 2 can rotate, the operation is more convenient.

[0031] The upper diameter of the limiting block 3 is smaller than its lower diameter, and a slope 31 is provided between the upper and lower outer rings of the limiting block 3 for transition, so that the firework tube can be easily guided and fitted onto the outer ring of the limiting block 3 through the slope 31. A sponge ring 32 is fixedly attached to the outer ring of the limiting block 3 below the slope 31, so that the sponge ring 32 can be deformed and abut against the inner surface of the firework tube to achieve a stable locking purpose.

[0032] A second rubber pad 34 is attached to the bottom surface of the limiting block 3 on the outer ring of the screw 33. When the screw 33 is screwed into the screw hole 21, the second rubber pad 34 contacts the surface of the base 1, which can reduce the wear on the bottom of the limiting block 3 or the surface of the base 1.

[0033] Example 2

[0034] The above-mentioned technical solution still suffers from insufficient positioning accuracy in actual operation. For example, some fireworks shells have multiple sizes of fireworks tubes, and their arrangement is also quite varied. The corresponding limiting block 3 may not be able to be precisely locked in any desired locking position by screwing the screw 33 into the screw hole 21. To solve this problem, this application proposes a second embodiment, which makes the following improvements while keeping other structures unchanged:

[0035] Please see Figure 5 and Figure 6 This design eliminates the need for screws 33 and second rubber pads 34 at the bottom of the limiting block 3. Instead, a magnet 35 is embedded and fixed at a lower position inside the limiting block 3. At the same time, an iron plate 22 is horizontally embedded and fixed inside the rotating plate 2. The limiting block 3 is placed on the surface of the base 1 by attracting the iron plate 22 with the magnet 35. This design allows limiting plates of different sizes to be magnetically attracted and locked in any position, making it convenient to match the production and use of fireworks shells with different shapes and distribution patterns.

[0036] A first rubber pad 23 is also attached and fixed to the surface of the base 1, and the limiting block 3 is placed on the surface of the base 1 to prevent slipping through the first rubber pad 23.

[0037] In use, according to the shape and size of the firework shell produced as required, a proper number and size of the limiting blocks 3 are selected, the corresponding limiting blocks 3 are locked in the appropriate positions on the surface of the base 1 by means of screwing the bottom screw rods 33 into the corresponding position screw holes 21 or by means of the magnet 35 attracting the iron plate 22, after all the limiting blocks 3 are locked in position, the firework shell can be pasted and assembled, the opening end of a single firework cylinder is aligned with the limiting blocks 3 after being smeared with glue on the outer circle, and then it is inserted downward to realize the rapid positioning of the single firework cylinder, and then the other firework cylinders are rapidly positioned in a short time to realize the rapid assembly and splicing of the firework shell in place, and finally a circle of wrapping paper is pasted on the outer circle of the firework shell to complete the assembly, the whole can be pulled upward and then downward, in order to facilitate the pasting and fixing of the wrapping paper during the operation process, the rotating plate 2 can be rotated above the base 1 through the rotating shaft 12.
