Detailed Implementation

[0030] 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.

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0032] During the filling of fireworks paper, the lack of a reliable positioning method can lead to inaccurate positioning of the fireworks body, causing paper insertion failure. Furthermore, the unstable dimensions of the fireworks body (a fireworks paper bowl composed of multiple fireworks tubes) can further cause positioning failure, resulting in paper filling failure. Therefore, this application provides a fireworks paper filling device that minimizes paper insertion failures caused by problems with the incoming fireworks body and inaccurate conveying and positioning mechanisms, thus improving equipment stability.

[0033] In this embodiment, the fireworks paper filling device includes a precision positioning component and a paper filling component. The precision positioning component includes a positioning structure and a first driving element. The positioning structure has multiple positioning bodies, each corresponding to a single tube at a different position on the fireworks body. As the first driving element drives the positioning structure downwards, the multiple positioning bodies are inserted into their respective single tubes on the fireworks body to position the fireworks body. The paper filling component includes a paper insertion structure, a punching structure, and at least one driving element. The driving element drives the paper insertion structure and the punching structure. The paper insertion structure has a paper insertion rod with a positioning pin at its end. The punching structure has a cylindrical punching head. As the driving element drives the paper insertion structure and the punching structure, the positioning pin on the paper insertion rod penetrates the through hole in the paper to position the paper. The punching head of the punching structure cuts off the paper after it has been positioned by the positioning pin, and the paper insertion rod pushes the cut-off paper into the corresponding single tube.

[0034] Specifically, the first driving element can be an electric device, pneumatic device, etc., used to drive the positioning structure to move up and down. Furthermore, as the first driving element drives the positioning structure to move downwards, multiple positioning elements are inserted into the corresponding single tubes on the firework body to position the firework body. After the precision positioning component completes the positioning of the firework body, the paper filling component begins to fill the firework paper tubes on the firework body with paper. Thanks to the secondary positioning performed by the precision positioning component before filling, paper insertion failures caused by problems with the firework body, paper tube feeding, and inaccurate conveying and positioning mechanisms are minimized, thus improving the operational stability of the firework production equipment.

[0035] Furthermore, the paper loading assembly includes a paper insertion structure, a punching structure, and at least one driving element. The driving element drives the paper insertion structure and the punching structure to operate. During paper loading, the paper insertion structure and the punching structure sequentially perform a first process, a second process, and a third process by moving downwards. Specifically, in the first process: as the paper insertion structure moves downwards, a positioning pin on the paper insertion rod first inserts into a through hole on the paper to position the paper. In the second process: after the positioning pin has inserted into the paper and completed the positioning, as the punching structure moves downwards, the punching head cuts off the paper positioned by the positioning pin. In the third step: the paper insertion rod pushes the cut-off paper into the corresponding single tube, completing one paper loading cycle.

[0036] The following is in conjunction with the appendix Figure 1 - Appendix Figure 8 The various possible implementation schemes provided in the embodiments of this application will be described in detail.

[0037] refer to Figures 1-8 The fireworks paper filling equipment includes: a precision positioning component 10 and a paper filling component 20. The precision positioning component 10 includes a positioning structure 12 and a first driving element 11; the positioning structure 12 is provided with a plurality of positioning bodies 121, and the plurality of positioning bodies 121 correspond one-to-one with a plurality of single tubes at different positions on the fireworks body; as the first driving element 11 drives the positioning structure 12 to move downward, the plurality of positioning bodies 121 are respectively inserted into the corresponding single tubes on the fireworks body to position the fireworks body. The paper loading assembly 20 includes: a paper insertion structure 21, a punching structure 22, and at least one driving element. The driving element is used to drive the paper insertion structure 21 and the punching structure 22 to move. The paper insertion structure 21 is provided with a paper insertion rod 212, and a positioning pin 213 is provided at the end of the paper insertion rod 212. The punching structure 22 is provided with a cylindrical punching head 222. As the driving element drives the paper insertion structure 21 and the punching structure 22 to move, the positioning pin 213 on the paper insertion rod 212 passes through the through hole on the paper to position the paper. The punching head 222 of the punching structure 22 punches off the paper after it has been positioned by the positioning pin 213. The paper insertion rod 212 pushes the punched paper into the corresponding single tube.

[0038] The positioning body 121 is used to position the firework body by inserting it into the firework tube. In one embodiment of this application, the lower end of the positioning body 121 is tapered, which facilitates the positioning body 121's entry into the firework tube and reduces the accuracy requirements for the initial position of the firework body. In a specific technical solution, the lower end of the positioning body 121 is configured as a conical structure.

[0039] refer to Figures 1-3 , Figure 5In one embodiment of this application, the punching structure 22 is provided with a row of punching heads 222, and the paper insertion structure 21 is provided with a row of paper insertion rods 212. The positions of the paper insertion rods 212 and the punching heads 222 correspond one-to-one, so as to fill the multiple rows of single tubes on the firework body row by row. On each side of a row of punching heads 222, a set of positioning bodies 121 is arranged, and each set of positioning bodies 121 includes at least two positioning bodies 121.

[0040] When the paper-filling assembly fills the firework tubes on the firework body row by row, each movement of the punching structure 22 and the paper insertion rod 212 of the paper-filling assembly fills one row of firework tubes. Furthermore, with each filling, the firework body moves forward one hole position to allow the next row of firework tubes above it to enter the filling position. Additionally, a set of positioning bodies 121 is arranged on both the front and rear sides of the filling position (i.e., one row of punching heads 222). Either the front or rear set of positioning bodies 121 can independently position the firework body. Therefore, when the firework tubes at the edge of the firework body reach the filling position of the paper-filling assembly, one set of positioning bodies 121 is located before the filling position and another set is located after the filling position. Either the set of positioning bodies 121 before or after the filling position is located above the firework body, allowing one set of positioning bodies 121 to be used for filling and positioning the firework body.

[0041] Specifically, when loading a firework body, the first row of firework tubes at its front edge first reaches the loading position of the paper loading assembly. At this time, a set of positioning bodies 121 before the loading position can be used for loading and positioning. Correspondingly, when loading the last row of firework tubes of a firework body, a set of positioning bodies 121 after the loading position can be used for loading and positioning.

[0042] refer to Figure 6 and Figure 7 In one embodiment of this application, the paper insertion structure 21 includes a base 211, and the upper end of the paper insertion rod 212 is swayably connected to the base 211. The paper loading assembly 20 also includes a limiting structure 23, which has a limiting hole 231. The limiting hole 231 is fitted around the outer periphery of the paper insertion rod 212 to limit the swing range of the paper insertion rod 212. Further, the limiting structure 23 includes a first limiting body 232 and a second limiting body 233, which are detachably connected together. The limiting hole 231 is formed by the first limiting body 232 and the second limiting body 233.

[0043] The upper end of the paper insertion rod 212 is oscillatingly connected to the base 211, allowing it to swing within a certain range. When the paper insertion rod 212 pushes the punched paper into the fireworks tube, its bottom end can oscillate adaptively. The paper insertion rod 212 passes through the limiting hole 231 on the limiting structure 23 and is limited by the limiting hole 231, allowing it to swing only within a certain range. This avoids excessive deviation and significantly improves the success rate of paper insertion without affecting the floating performance, thus enhancing equipment stability. Furthermore, since the first limiting body 232 and the second limiting body 233 are detachably connected together, and the limiting hole 231 is formed by the combination of the first limiting body 232 and the second limiting body 233, the assembly of the limiting structure 23 is easier.

[0044] In one embodiment of this application, the installation height of the limiting structure 23 is adjustable. When the height of the limiting structure 23 changes, the limiting hole 231 is located at different positions of the paper insertion rod 212. It should be understood that the higher the limiting structure 23 and the limiting hole 231 move, the larger the swing range of the paper insertion rod 212 defined by the limiting hole 231; conversely, the lower the limiting structure 23 and the limiting hole 231 move, the smaller the swing range of the paper insertion rod 212 defined by the limiting hole 231. Therefore, the swing range of the paper insertion rod 212 can be adjusted by adjusting the installation height of the limiting structure 23.

[0045] In one embodiment of this application, the paper insertion structure 21 includes a base 211, and the upper end of the paper insertion rod 212 is swayably connected to the base 211. The paper filling assembly 20 includes a second driving element 24; the second driving element 24 is used to drive the punching structure 22 to move downward; while moving downward, the punching structure 22 abuts against the base 211 and pushes the paper insertion structure 21 to move downward synchronously, so that the positioning pin 213 on the paper insertion rod 212 passes into the through hole on the paper to position the paper, and the punching head 222 of the punching structure 22 punches off the paper after the positioning pin 213 has positioned it. The paper filling assembly 20 includes a third driving element 25; the third driving element 25 is used to drive the base 211 to continue to move downward, so that the paper insertion rod 212 pushes the punched paper into the corresponding single tube.

[0046] For example, during the filling process, the paper filling assembly 20 firstly, in the first stage, the second driving element 24 drives the punching structure 22 to move downwards. Simultaneously, the punching structure 22 abuts against the base 211 and pushes the paper insertion structure 21 downwards. The positioning pin 213 on the paper insertion rod 212 inserts into the through hole on the paper to position it. Next, in the second stage, after the positioning pin 213 has positioned the paper, the punching head 222 of the punching structure 22 cuts the paper off. Finally, in the third stage, the third driving element 25 drives the base 211 to continue moving downwards, and the paper insertion rod 212 pushes the cut paper into the corresponding single tube, completing the paper filling.

[0047] refer to Figures 6-8 The punching structure 22 is provided with a pusher 221, which is used to abut against the base 211 and push the paper insertion structure 21 to move down synchronously when the punching structure 22 moves downward.

[0048] It should be noted that in existing paper filling assemblies, the stroke of the paper insertion rod and the punching structure is controlled by adjusting the air pressure of the paper insertion cylinder, the position sensor, or the spring pressure. This ensures that the punching head of the punching structure cuts the paper after the positioning pin has positioned itself. This method is not stable enough, and the timing is inconsistent. It can lead to the paper insertion rod inserting into the paper later than the punching, resulting in positioning failure, or the paper insertion rod inserting into the paper too early, causing paper damage, thus affecting equipment stability and product quality. In this embodiment, the punching structure, while moving downwards, abuts against the base and pushes the paper insertion structure downwards synchronously, allowing the positioning pin on the paper insertion rod to penetrate the through-hole in the paper to position it. The punching head of the punching structure then cuts off the paper after the positioning pin has positioned itself. This mechanical linkage between the punching structure and the paper insertion rod ensures the relative sequence and timing of their downward movements. Therefore, the above solution improves the stability and production efficiency of the paper filling equipment and saves costs.

[0049] This application also provides a fireworks production line, including the aforementioned fireworks paper filling equipment. In a specific fireworks production line structure, a paper filling device, a military-grade gunpowder filling device, and an inner cylinder filling device are provided.

[0050] The fireworks production line provided in this application includes the aforementioned fireworks paper filling equipment. This fireworks paper filling equipment is equipped with a precision positioning component. By utilizing the secondary positioning performed by the precision positioning component before filling, paper insertion failures caused by issues with the incoming firework body and paper tube, as well as inaccurate conveying and positioning mechanisms, are minimized, thus improving the operational stability of the fireworks production equipment. In one embodiment, the paper filling component further includes a limiting structure. The paper insertion rod passes through a limiting hole on the limiting structure and is limited by the limiting hole, allowing the paper insertion rod to swing within a certain range, avoiding excessive deviation. This significantly increases the success rate of paper insertion without affecting the floating performance, thereby improving equipment stability. Furthermore, in some embodiments, during the paper filling process, the punching structure, while moving downwards, abuts against the base and pushes the paper insertion structure downwards synchronously, so that the positioning pin on the paper insertion rod penetrates the through hole on the paper to position the paper. The punching head of the punching structure then cuts off the paper after the positioning pin has positioned it. This mechanical linkage ensures the relative sequence and timing of the actions of the punching structure and the paper insertion rod as they move downwards. Therefore, this solution improves the stability and production efficiency of the paper filling equipment while saving costs.
