In existing paper-filling equipment for fireworks production, the paper tape utilization rate is low, resulting in serious waste, especially when the interval between the launch holes of the fireworks is large, leaving a large blank area between the punching holes.
The paper feed filling equipment includes a frame, a punching mechanism, a roller mechanism, and a paper tape offset assembly. The roller mechanism clamps the paper tape and pulls it under the drive. Combined with the paper tape offset assembly, the paper tape position is adjusted in the vertical direction, so that the punching mechanism can punch the same area multiple times to ensure that the punching holes are staggered.
This improves the utilization rate of paper tape, reduces production costs, and minimizes paper tape waste by staggering the multiple punching holes.

In the following description, specific details such as particular configurations and components are provided merely to aid in a comprehensive understanding of the embodiments of this application. Therefore, those skilled in the art should understand that various changes and modifications can be made to the embodiments described herein without departing from the scope of protection of this application. Furthermore, for clarity and brevity, descriptions of known functions and structures have been omitted.
[0023] It should be noted that, where there is no conflict, the embodiments and features described in this application can be combined with each other.
[0024] In fireworks production, paper barbats refer to circular pieces of paper used inside fireworks tubes for sealing, isolation, and fixation. During the filling of the fireworks, the filling equipment punches paper barbats from a paper strip and inserts them into the launch holes of the fireworks. However, with existing paper barbat filling equipment, when the intervals between the launch holes on the fireworks are large, a large blank area is left between the punched holes after the paper strip is cut, resulting in low utilization and significant waste. Therefore, this application improves the existing paper barbat filling equipment, as detailed below with reference to the accompanying drawings.
[0025] refer to Figures 1-3 This application provides a paper bab filling device, which includes a frame 10, a punching mechanism 20, a roller mechanism 30, and a paper tape offset assembly.
[0026] A punching mechanism 20 is arranged on the frame 10 for punching paper strips from the paper tape K and pushing the paper strips into the launching holes of the firework bomb W. A roller mechanism 30 is arranged on the output side of the paper tape K of the punching mechanism 20; the roller mechanism 30 includes multiple rollers and a first drive device; the first drive device is used to drive the rollers to rotate; the multiple rollers can clamp or release the paper tape K; when the multiple rollers clamp the paper tape K, the rollers can pull the paper tape K to move through the punching mechanism 20 under the drive of the first drive device; when the multiple rollers release the paper tape K, the paper tape K can be positionally adjusted in the A direction; wherein, the A direction is perpendicular to the direction of movement of the paper tape K. A paper tape offset assembly is arranged on the input side of the paper tape K of the roller mechanism 30 for driving the paper tape K in the punching mechanism 20 to be positionally adjusted in the A direction.
[0027] When the firework pellet is fed into the loading position at the bottom of the punching mechanism 20, the punching mechanism 20 can punch out paper strips on the paper tape K and push the paper strips into the launch holes of the firework pellet W. The punching mechanism is an essential component of the paper strip filling device. Exemplarily, the punching mechanism includes a paper insertion structure and a punching structure, wherein the punching structure is used to punch out paper strips on the paper tape, and the paper insertion structure is used to push the paper strips downward into the launch holes of the firework pellet.
[0028] The roller mechanism 30 is arranged on the output side of the paper tape K of the punching mechanism 20. When multiple rollers clamp the paper tape K, the first drive device can drive one or more rollers to rotate, and the rotation of the rollers can pull the paper tape K to move in the x-direction. The first drive device can control the movement stroke of the paper tape K by controlling the rotation angle of the rollers. The first drive device can be composed of one or more drive elements to drive one or more rollers to rotate. In some embodiments, the first drive device includes only one drive element, which drives one of the rollers to rotate. The drive element can be an electric element or a pneumatic element, such as an electric motor or a pneumatic motor. In a specific embodiment, the first drive device is set as a servo motor.
[0029] In some embodiments of this application, the roller mechanism 30 is provided with a first roller 31 and a second roller 32; the first roller 31 and the second roller 32 can approach each other to clamp the paper tape K passing between them, or move away from each other to release the paper tape K passing between them. Further, a first driving device is poweredly connected to the first roller 31 or the second roller 32 to drive the first roller 31 or the second roller 32 to rotate.
[0030] It should be understood that, in this application, the rollers of the roller mechanism 30 are capable of clamping or releasing the paper tape K. The paper tape K passes between the rollers, and the rollers can move closer together to clamp the paper tape K passing between the rollers, or move further apart to release the paper tape K passing between the rollers. Here, the adjustment design of the rollers is within the scope of the prior art and will not be described in detail.
[0031] The paper tape offset assembly is arranged on the input side of the paper tape K in the roller mechanism 30. When multiple rollers release the paper tape K, the paper tape offset assembly can drive the paper tape K in the punching mechanism 20 to adjust its position in the A direction. Figure 3 and Figure 5 The image shows the direction of movement of the paper tape K, which is the x-direction. The A-direction is perpendicular to the direction of movement of the paper tape K. The paper tape offset component drives the paper tape K in the punching mechanism 20 to adjust its position in the A-direction.
[0032] In some embodiments of this application, the paper tape offset assembly includes multiple paper tape driving units. Each paper tape driving unit includes a clamping mechanism 41 and a second driving device 42; the clamping mechanism 41 is capable of clamping or releasing the paper tape K; the second driving device 42 is connected to the clamping mechanism 41 to drive the clamping mechanism 41 to move, enabling the clamping mechanism 41 to pull the paper tape K for position adjustment. (Reference) Figure 3 and Figure 4 In one specific embodiment, the clamping mechanism 41 is a pneumatic gripper used to clamp or release the edge of the paper tape K.
[0033] The second drive unit 42 can be configured as a cylinder. (Reference) Figure 3 When the clamping mechanism 41 clamps the edge of the paper tape K, the second drive device 42 can pull the paper tape K to shift along the A direction. When the second drive device 42 (cylinder) extends or the clamping mechanism 41 releases the paper tape K, the paper tape K will return to its initial position. Therefore, driven by the second drive device 42, the paper tape K in the punching mechanism 20 is positionally adjusted along the A direction, and can either shift perpendicular to the paper tape's movement direction based on its initial position, or retract to its initial position.
[0034] In some embodiments of this application, the paper tape offset assembly includes one or more first paper tape driving units 40a and one or more second paper tape driving units 40b. The first paper tape driving unit 40a is arranged on the input side of the paper tape K of the die-cutting mechanism 20, and the second paper tape driving unit 40b is arranged on the output side of the paper tape K of the die-cutting mechanism 20. In this design, the first paper tape driving unit 40a and the second paper tape driving unit 40b are respectively arranged on both sides of the die-cutting mechanism 20, and can simultaneously drive the paper tape K from both sides of the die-cutting mechanism 20 to adjust its position along the A direction.
[0035] In one embodiment of this application, the paper strip punching positions of the punching mechanism 20 are aligned in both the longitudinal and transverse directions, so that the punching holes formed by the paper strip K after one punching are aligned in both the longitudinal and transverse directions.
[0036] Figure 6 The diagram shows the punching holes formed after the punching mechanism 20 punches the same area of the paper tape twice. Figure 5 and Figure 6In the diagram, the first cutting hole K1 is represented by a thick line, and the second cutting hole K2 is represented by a thin line. The first cutting hole K1 is formed after the cutting mechanism 20 performs the first cutting on the paper strip, and the first cutting holes K1 are aligned vertically and horizontally. Based on the first cutting, the cutting mechanism 20 performs a second cutting on the paper strip, forming the second cutting hole K2, which is also aligned vertically and horizontally.
[0037] After the first punching of the paper tape by the punching mechanism 20, first punching holes K1 are formed. Due to the large spacing between the first punching holes K1, there is a large unused blank area between them. The roller mechanism and the paper tape offset assembly adjust the position of the paper tape by driving it, allowing the punching mechanism 20 to align with the blank area between the first punching holes K1 for a second punching. Finally, after two punchings, the paper tape forms first punching holes K1 and second punching holes K2.
[0038] The roller mechanism controls the position of the paper strip in its direction of movement, while the paper strip offset component controls the lateral offset of the paper strip K (the offset along direction A). By adjusting the position of the paper strip, the roller mechanism and the paper strip offset component enable the punching mechanism to perform multiple paper strip punches on the same area of the paper strip. The punching holes of the multiple paper strip punches are staggered, thereby improving the utilization rate of the paper strip and reducing costs.
[0039] In some embodiments of this application, the paper filling device further includes a conveying mechanism 50; the conveying mechanism 50 is used to convey the firework pellets W. The conveying mechanism 50 passes through the punching mechanism 20; when the firework pellets W on the conveying mechanism 50 move to the position of the punching mechanism 20, the punching mechanism 20 punches out paper pellets on the paper belt K and pushes the paper pellets into the launching holes of the firework pellets W. In a specific technical solution, the conveying mechanism 50 is a belt conveyor mechanism.
[0040] This application also provides a fireworks production line, which includes the paper bab filling equipment provided in the previous section. In one specific embodiment, the fireworks production line can be used to produce combination fireworks, including military-grade gunpowder filling equipment, paper bab filling equipment, and effect inner tube filling equipment.
[0041] The paper strip filling device includes a frame 10, a punching mechanism 20, a roller mechanism 30, and a paper strip offset assembly. The punching mechanism 20 is arranged on the frame 10 and is used to punch out paper strips from the paper strip K and push the paper strips into the launching holes of the firework pyrotechnic W. The roller mechanism 30 is arranged on the output side of the paper strip K of the punching mechanism 20; the roller mechanism 30 includes multiple rollers and a first drive device; the first drive device is used to drive the rollers to rotate; the multiple rollers can clamp or release the paper strip K; when the multiple rollers clamp the paper strip K, the rollers can pull the paper strip K to move through the punching mechanism 20 under the drive of the first drive device; when the multiple rollers release the paper strip K, the paper strip K can be positionally adjusted in direction A; wherein direction A is perpendicular to the direction of movement of the paper strip K. The paper strip offset assembly is arranged on the input side of the paper strip K of the roller mechanism 30 and is used to drive the paper strip K in the punching mechanism 20 to adjust its position in direction A.
[0042] In this application, when multiple rollers clamp the paper tape, the rollers can pull the paper tape to move through the punching mechanism under the drive of the first driving device; when the multiple rollers release the paper tape, the paper tape offset assembly can drive the paper tape to adjust its position in direction A; wherein, direction A is perpendicular to the direction of paper tape movement. By adjusting the position of the paper tape, the roller mechanism and the paper tape offset assembly enable the punching mechanism to perform multiple paper tape punches on the same area of the paper tape, and the punching holes of the multiple paper tape punches are staggered, thereby improving the utilization rate of the paper tape and reducing costs.
[0043] It should be noted that, Figures 1-3 The punching holes on the paper tape are not shown in the image. Figure 5 and Figure 6 The image shows the punching holes formed after the punching mechanism punches the paper tape twice.
