[0001] This application relates to the field of fireworks production equipment technology, and in particular to a fireworks paper filling device and a fireworks production line. Background Technology

[0002] Combination fireworks consist of multiple individual tubes arranged together, producing sound, light, color, and floating effects when ignited. The materials inside each individual tube of combination fireworks are usually filled automatically by automated equipment, including the filling of gunpowder, firework paper, and effect inner tubes.

[0003] During the paper filling process of fireworks, the paper filling equipment cuts paper strips from the paper tape and inserts them into the various launch holes of the fireworks. Ordinary fireworks paper filling equipment has low paper tape utilization and results in significant waste.

[0004] To improve the utilization rate of paper tape and reduce costs, some newly emerging fireworks paper filling equipment on the market can perform two paper cuttings on the same area of ​​the paper tape, with the holes from the two cuttings staggered. However, the aforementioned new equipment cannot be applied to fireworks pellets with irregular hole distribution. Utility Model Content

Detailed Implementation

[0024] The following are specific embodiments of this application, described in conjunction with the accompanying drawings, to further illustrate the technical solutions of this application. However, this application is not limited to these embodiments. 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.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0026] It should be noted that, in order to improve the utilization rate of paper strips and reduce costs, some newly emerging fireworks paper filling equipment on the market can perform two paper cuttings on the same area of ​​the paper strip, with the holes in the two cuttings being staggered. For example, the paper filling equipment disclosed in Chinese Patent CN202620747815.4 and the fireworks paper filling equipment disclosed in CN202620747814.X. However, the aforementioned new equipment cannot be applied to fireworks with irregularly distributed holes. For example, some fireworks have multiple hole distributions in different areas, and the holes in different areas are not completely aligned. After the cutting mechanism performs the first cutting of a section of paper strip, it cannot reuse the remaining blank area of ​​that section of paper strip by adjusting its position.

[0027] Specifically, Figure 5 This illustration depicts a firework pyrotechnic with an irregularly distributed aperture. The pyrotechnic pyrotechnic 10 has a first region 11 and a second region 12, with different aperture distributions in the first region 11 and the second region 12. It is evident that the aperture spacing in the first region 11 is relatively large, leaving a large blank area between the punched apertures after the paper tape is punched; conversely, the aperture spacing in the second region 12 is relatively small, leaving a smaller blank area between the punched apertures after the paper tape is punched, sometimes even insufficient for reuse. Figure 5 The firework pellet 10 shown cannot utilize the firework paper filling equipment described in the prior art to save paper tape.

[0028] refer to Figures 1-4 The fireworks paper filling equipment includes a frame, a punching mechanism 30, a roller mechanism, and a drive assembly. The punching mechanism 30, arranged on the frame, punches paper strips from a paper strip and pushes them into the firing holes of the fireworks. The roller mechanism includes a first roller mechanism 21 and a second roller mechanism 22, respectively arranged on both sides of the punching mechanism 30, to guide the paper strip along the x-direction to pass through the punching mechanism 30 and to control the position of the paper strip in the x-direction. The drive assembly drives the paper strip to adjust its position along the y-direction, wherein there is an angle between the y-direction and the x-direction.

[0029] When the firework pellet is fed into the loading position at the bottom of the punching mechanism 30, the punching mechanism 30 punches out paper pieces from the paper strip and pushes the paper pieces into the firing holes of the firework pellet. The punching mechanism is an essential component of the firework paper filling equipment. Exemplarily, the punching mechanism includes a paper insertion structure and a punching structure, wherein the punching structure is used to punch out paper pieces from the paper strip, and the paper insertion structure is used to push the paper pieces downward into the firing holes of the firework pellet. The punching mechanism is a conventional component of firework paper filling equipment in the prior art and is widely present in existing firework production equipment; its specific structure will not be described in detail here. In some technical solutions, the punching mechanism 30 also integrates a perforation structure for inserting through holes at the corresponding paper positions before punching. In some technical solutions, a punching mechanism is arranged separately from the blanking mechanism 30. The punching mechanism can be located between the first roller mechanism 21 and the second roller mechanism 22. The paper tape first arrives at the punching mechanism for punching, and then enters the blanking mechanism 30 after the paper tape is punched. It should be noted that whether the punching structure is integrated into the blanking mechanism 30 or a separate punching mechanism is set up, it is within the scope of existing technology and will not be elaborated here.

[0030] The punching mechanism 30 includes multiple independently operating sub-punching mechanisms, each corresponding to a firing hole area on the fireworks display. The distribution of punching hole positions in each sub-punching mechanism is not entirely the same. Here, the different distribution of punching hole positions in the sub-punching mechanisms means that the hole spacing between corresponding punching hole positions is not completely consistent, which prevents the sub-punching mechanisms from using the same paper tape position adjustment amount to punch paper sheets multiple times on the same paper tape area.

[0031] When the fireworks paper filling equipment is working, the first roller mechanism 21 and the second roller mechanism 22 guide the paper strip to move along the x-direction to pass through the punching mechanism 30 and control the position of the paper strip in the x-direction; the drive assembly is used to drive the paper strip to adjust its position along the y-direction. Under the drive of the roller mechanism and the drive assembly, the paper strip can be adjusted in both the y-direction and x-direction, so that the punching mechanism 30 can punch paper strips at different positions on the paper strip. In this application, the punching mechanism 30 includes multiple independently operating sub-punching mechanisms, each sub-punching mechanism corresponding to a region of the firing hole on the fireworks. The roller mechanism and the drive assembly can adjust the position of the paper strip for one or more of the sub-punching mechanisms, so that one or more sub-punching mechanisms can punch paper strips multiple times on their respective corresponding paper strip regions. The punching hole positions of the multiple paper strip punches are staggered, thereby improving the utilization rate of the paper strip and reducing costs.

[0032] The firework paper filling equipment provided in this application can be applied to firework pellets with multiple hole distributions. Each sub-punching mechanism can correspond to the firing holes in a region of the firework pellet to deal with firework pellets with multiple hole distributions and improve the utilization rate of paper strips for some or all areas of the firework pellet.

[0033] The following is based on Figure 5 The firework projectile shown will be explained in detail. Figure 5 The illustration shows a firework pellet 10 with an irregular hole distribution in the prior art. The firework pellet 10 has a first region 11 and a second region 12, and the hole distribution of the firing holes in the first region 11 and the second region 12 is different. The hole spacing of the firing holes in the first region 11 is relatively large, and after the paper tape is punched, a large blank area is left between the punched holes. These blank areas can be reused for punching. The hole spacing of the firing holes in the second region 12 is relatively small, and after the paper tape is punched, the blank area left between the punched holes is small and not enough for reuse.

[0034] In some embodiments of this application, the punching mechanism 30 includes a first sub-punching mechanism 31 and a second sub-punching mechanism 32; the first sub-punching mechanism 31 corresponds to the launching hole of the first region 11 on the firework pyrotechnic 10; and the second sub-punching mechanism 32 corresponds to the launching hole of the second region 12 on the firework pyrotechnic 10.

[0035] Figure 3 The roller mechanism and drive assembly are shown. Figure 3 In the illustrated structure, the first roller mechanism 21 and the second roller mechanism 22 can guide the paper tape to move along the x-direction to update the paper tape below the punching mechanism 30. Furthermore, the first roller mechanism 21 and the second roller mechanism 22 can also be used to control the position of the paper tape in the x-direction. A driving assembly acts on the first roller mechanism 21 and the second roller mechanism 22, adjusting the position of the paper tape in the y-direction by driving the first roller mechanism 21 and the second roller mechanism 22 to move along the y-direction. In a specific embodiment, the driving assembly includes a first driving element 41 and a second driving element 42; the first driving element 41 drives the first roller mechanism 21 to move; the second driving element 42 drives the second roller mechanism 22 to move; under the drive of the first driving element 41 and the second driving element 42, the first roller mechanism 21 and the second roller mechanism 22 move synchronously to adjust the position of the paper tape in the y-direction. In this structural configuration, the first driving element 41 and the second driving element 42 can be configured as electric elements, pneumatic elements, etc., specifically as cylinders.

[0036] For example, when the fireworks paper filling equipment is working, the first sub-cutting mechanism 31 and the second sub-cutting mechanism 32 can perform cutting simultaneously or separately. When a new strip of paper enters below the second roller mechanism 22, the second sub-cutting mechanism 32 cuts paper pieces from the paper strip and pushes the paper pieces into the firing holes of the second region 12 of the fireworks blasting head 10. However, the overall spacing between the firing holes in the second region 12 is small, and the blank area left between the cutting holes after the paper strip is cut is small and insufficient for reuse. Therefore, the paper strip cut by the second sub-cutting mechanism 32 cannot be reused. When a new strip of paper enters below the first sub-cutting mechanism 31, the first sub-cutting mechanism 31 performs the first cut on the paper strip, cutting out paper pieces and pushing them into the firing holes of the first region 11 of a firework pyrotechnic 10. The firing holes in the first region 11 have a large spacing, leaving a large blank area between the holes after the first cut. These blank areas can be used for cutting again. At this time, driven by the roller mechanism and the drive assembly, the paper strip is positioned along the y and x directions so that the first sub-cutting mechanism 31 is aligned with the blank area between the holes after the first cut. The first sub-cutting mechanism 31 then performs a second cut, cutting out paper pieces and pushing them into the firing holes of the first region 11 of the next firework pyrotechnic 10. In the above process, the first sub-cutting mechanism 31 performs two cuts on the same paper strip area, improving the utilization rate of the paper strip.

[0037] Figure 6 A schematic diagram of the firework pyrotechnics and paper strip is shown. The first segment a, the second segment b, and the third segment c of the paper strip 60 have punched holes 61 formed after punching. The punched holes on the first segment a of the paper strip 60 are formed by the first sub-punching mechanism 31 through two punching operations, and the punched holes formed by the two punching operations are distinguished by two different thicknesses of lines, corresponding to the firing holes of the first region 11 of the two firework pyrotechnics 10 respectively. Clearly, the first sub-punching mechanism 31 adjusts its position along the y-direction and x-direction between the two punching operations. The punched holes on the first segment b of the paper strip 60 are formed by the second sub-punching mechanism 32 through one punching operation, corresponding to the firing holes of the second region 12 of one firework pyrotechnic. The punched holes on the first segment c of the paper strip 60 are formed by the second sub-punching mechanism 32 through one punching operation, corresponding to the firing holes of the second region 12 of one firework pyrotechnic. Figure 6 In the structure shown, the punching mechanism punches the first segment a of the paper tape 60 twice, which effectively improves the utilization rate of the paper tape.

[0038] Driven by the roller mechanism and drive assembly, the paper belt can be positioned along the y-direction and the x-direction, with an angle between the y-direction and the x-direction. In some technical solutions, the y-direction and the x-direction are perpendicular to each other.

[0039] In some embodiments of this application, the drive assembly acts directly on the paper tape, enabling direct position adjustment of the paper tape along the y-direction while the first roller mechanism 21 and the second roller mechanism 22 are releasing the paper tape. The rollers of the first roller mechanism 21 and the second roller mechanism 22 can be driven by a motor. With this configuration, the rollers of the first roller mechanism 21 and the second roller mechanism 22 can clamp or release the paper tape. The paper tape passes between the rollers, and the rollers can move closer together to clamp the paper tape passing between the rollers, or move further apart to release the paper tape passing between the rollers. Here, the roller adjustment design is within the scope of prior art and will not be elaborated further. When the drive assembly drives the paper tape, the first roller mechanism 21 and the second roller mechanism 22 need to loosen the paper tape so that it can be driven by the drive assembly to move along the y-direction. For example, in the paper filling device disclosed in Chinese Patent CN202620747815.4, the drive assembly can pull the paper tape after clamping its edge.

[0040] In some embodiments of this application, the fireworks paper filling device further includes a conveying mechanism 50; the conveying mechanism 50 is used to convey fireworks pellets. The conveying mechanism 50 passes through a punching mechanism; when the fireworks pellet on the conveying mechanism 50 moves to the position of the punching mechanism, the punching mechanism punches out paper pieces on the paper belt and pushes the paper pieces into the launching holes of the fireworks pellets. In a specific technical solution, the conveying mechanism is a belt conveyor mechanism.

[0041] This application also provides a fireworks production line, which includes the aforementioned fireworks paper filling equipment. In one specific embodiment, the fireworks production line can be used to produce combination fireworks, including military-grade gunpowder filling equipment, paper filling equipment, and effect inner tube filling equipment.

[0042] The fireworks paper filling equipment includes a frame, a punching mechanism, a roller mechanism, and a drive assembly. The punching mechanism, arranged on the frame, punches paper pieces from the paper strip and pushes them into the launch holes of the fireworks. The roller mechanism guides the paper strip along the x-direction to pass through the punching mechanism and controls the position of the paper strip in the x-direction. The drive assembly drives the paper strip to adjust its position along the y-direction, where there is an angle between the y-direction and the x-direction. The punching mechanism includes multiple independently operating sub-punching mechanisms, each corresponding to a launch hole area on the fireworks.

[0043] The fireworks production line has the aforementioned fireworks paper filling equipment. For details on the fireworks paper filling equipment, please refer to the previous section. It will not be repeated here.

[0044] In summary, in this application, the punching mechanism includes multiple independently operating sub-punching mechanisms, each corresponding to a firing hole in a region of the firework pyrotechnic. The roller mechanism and drive assembly can adjust the paper strip position for one or more of the sub-punching mechanisms, enabling each sub-punching mechanism to punch multiple paper strips in its corresponding paper strip region. The punching hole positions of the multiple paper strip punches are staggered, thereby improving the utilization rate of the paper strip and reducing costs.
