Detailed Implementation

[0031] 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.

[0032] It should be noted that, where there is no conflict, the embodiments and features described in this application can be combined with each other.

[0033] During the production of the inner cylinder, it is necessary to quantitatively fill it with de-icing agent and brightening beads. The accuracy of the material filling and the safety of workers must be ensured during production. Therefore, the technical advantage of this application lies in providing an automated inner cylinder filling device with high filling accuracy and high safety.

[0034] The fireworks charging assembly can be used for inner tube charging, quantitatively loading opening powder, bright beads, etc., into the inner tube. Furthermore, it should be understood that the fireworks charging assembly provided in this application can also be applied to the outer tube charging of combination fireworks, achieving the same technical effect.

[0035] refer to Figures 1-3 The fireworks charging assembly includes a metering template 10, a discharge plate 20, and a discharge control mechanism 30. The metering template 10 has multiple rows of metering holes 11; the discharge plate 20 has multiple rows of discharge holes 21; the discharge holes 21 correspond one-to-one with the metering holes 11; the upper surface of the discharge plate 20 is in contact with the lower surface of the metering template 10 to ensure one-to-one engagement of the discharge holes 21 and the metering holes 11; the discharge control mechanism 30 includes multiple rotating components 31 and a drive device 34; an assembly groove 22 is provided on the upper surface of the discharge plate 20 to accommodate the rotation of the rotating components 31; a row of baffle plates 311 are arranged on the rotating components 31; each rotating component 31 corresponds to a row of metering holes 11, and the baffle plates 311 on it are arranged one-to-one in the corresponding row of discharge holes 21; the drive device 34 drives the rotating components 31 to rotate, so that the baffle plates 311 on the rotating components 31 open or close the metering holes 11.

[0036] When the fireworks charging assembly is in operation, firstly, raw materials are loaded into the metering holes 11 of the metering template 10. The size of the metering holes 11 determines the volume of the raw materials. The material feeding control mechanism 30 is located below the metering template 10 and includes a rotating component 31 and a driving device 34. The rotating component 31 is housed in the assembly groove 22 of the feeding plate 20, so the upper surface of the feeding plate 20 can be attached to the lower surface of the metering template 10. As the driving device 34 rotates the rotating component 31, the baffle plate 311 of the rotating component 31 can either seal or open the bottom of the metering hole 11. When the baffle plate 311 of the rotating component 31 seals the bottom of the metering hole 11, raw materials can be loaded into the metering hole 11. When the baffle plate 311 of the rotating component 31 rotates and opens the bottom of the metering hole 11, the raw materials in the metering hole 11 can fall into the feeding hole 21 and then fall downwards into the paper tube. Since there is no gap between the discharge plate 20 and the metering template 10, the raw material in the metering hole 11 will not leak into the gap between the discharge plate 20 and the metering template 10 when it falls into the discharge hole 21, resulting in high filling accuracy and high safety.

[0037] The drive device 34 is used to drive the rotating component 31 to rotate. It can be an electric device or a pneumatic device, specifically an electric cylinder, a pneumatic cylinder, a motor, etc.

[0038] In one embodiment of this application, the baffle plate 311 on the rotating member is fixed in a detachable manner. In a specific embodiment, the baffle plate 311 on the rotating member is installed by screws.

[0039] In one embodiment of this application, reference is made to Figure 3 The opening of the discharge hole 21 on the upper surface of the discharge plate 20 is larger than its opening on the lower surface of the discharge plate 20. The larger opening of the discharge hole 21 on the upper surface of the discharge plate 20 is beneficial for receiving the raw material falling from the upper metering hole 11; the smaller opening of the discharge hole 21 on the upper surface of the discharge plate 20 is beneficial for guiding the raw material into the lower paper tube.

[0040] In one embodiment of this application, the rotating members 31 are divided into multiple groups, and each group of rotating members 31 is configured with a driving device 34; a group of rotating members 31 is composed of several rotating members 31; the rotating members 31 in each group can move synchronously to synchronously open or close the metering orifice 11 corresponding to that group of rotating members 31.

[0041] Specifically, since each rotating component 31 corresponds to a row of metering holes 11, and the baffles 311 on it are arranged one-to-one in the corresponding row of discharge holes 21, each rotating component 31 can control the opening and closing of a row of metering holes 11. Here, the rotating components 31 are divided into multiple groups, and each group of rotating components 31 is equipped with a driving device 34. Therefore, each driving device 34 can control the opening and closing of several rows of metering holes 11, so that the metering holes 11 are divided into multiple groups and controlled separately by multiple driving devices 34, thereby improving the flexibility of paper tube filling.

[0042] It should be noted that each group of rotating components 31 may contain one or more rotating components 31, and the number of rotating components 31 in each group may be the same or different. In addition, in this application, the rotating components 31 may be divided into n groups, for example, 2, 3, 4, 5, 6, 7, ..., which can be set as needed. The following is a specific explanation using 2 groups as an example.

[0043] In one embodiment of this application, each group of rotating components 31 is correspondingly configured with a transverse connecting rod. Each rotating component 31 and its corresponding transverse connecting rod are connected by a swing rod 33, enabling the rotating components 31 in each group to move synchronously to open or close the metering orifice 11 corresponding to that group of rotating components 31. The transverse connecting rod and the swing rod 33 are arranged on the side of the blanking plate 20. The connection between the swing rod 33 and the transverse connecting rod is configured to be rotatable relative to each other, while the connection between the swing rod 33 and the rotating component 31 is configured to be non-rotatable relative to each other. Each group of rotating components 31 forms an actuation mechanism through a transverse connecting rod and several swing rods 33, which is driven by a drive device 34. Each group of rotating components 31 belongs to a different actuation mechanism and is independent of each other.

[0044] refer to Figures 4-9 In one embodiment of this application, the rotating component 31 is divided into a first group of rotating components 31a and a second group of rotating components 31b; the transverse connecting rod includes a first transverse connecting rod 32a and a second transverse connecting rod 32b; the first group of rotating components 31a corresponds to the first transverse connecting rod 32a, and the second group of rotating components 31b corresponds to the second transverse connecting rod 32b; the first transverse connecting rod 32a and the second transverse connecting rod 32b are arranged on opposite sides of the blanking plate 20. Further, the rotating component is divided into a first group of rotating components 31a and a second group of rotating components 31b; the first group of rotating components 31a and the second group of rotating components 31b are arranged alternately.

[0045] Specifically, the first set of rotating components 31a corresponds to the first driving device, and the second set of rotating components 31b corresponds to the second driving device. The metering orifices are correspondingly divided into a first set of metering orifices and a second set of metering orifices. Under the drive of the first driving device, the first transverse connecting rod 32a can drive the first set of rotating components 31a to move synchronously, causing the first set of rotating components 31a to open or close the first set of metering orifices synchronously. Under the drive of the second driving device, the second transverse connecting rod 32b can drive the second set of rotating components 31b to move synchronously, causing the second set of rotating components 31b to open or close the second set of metering orifices synchronously.

[0046] This application embodiment also provides a fireworks inner tube production device, which includes the fireworks loading assembly provided in the previous part. The inner tube loading device also includes a transfer template 40, on which multiple rows of limiting holes are distributed; the limiting holes are used to place the paper tube 50; the limiting holes correspond one-to-one with the dropping holes 21. In this embodiment, the fireworks loading assembly is used for inner tube loading, quantitatively loading opening powder, bright beads, etc. into the inner tube (paper tube).

[0047] When the fireworks charging assembly is in operation, firstly, raw materials are loaded into the metering holes 11 of the metering template 10. The size of the metering holes 11 determines the volume of the raw materials. The material feeding control mechanism 30 is located below the metering template 10 and includes a rotating component 31 and a driving device 34. The rotating component 31 is housed in the assembly groove 22 of the feeding plate 20, so the upper surface of the feeding plate 20 can be attached to the lower surface of the metering template 10. As the driving device 34 rotates the rotating component 31, the baffle plate 311 of the rotating component 31 can either seal or open the bottom of the metering hole 11. When the baffle plate 311 of the rotating component 31 seals the bottom of the metering hole 11, raw materials can be loaded into the metering hole 11. When the baffle plate 311 of the rotating component 31 rotates and opens the bottom of the metering hole 11, the raw materials in the metering hole 11 can fall into the feeding hole 21 and then fall downwards into the paper tube. Since there is no gap between the discharge plate 20 and the metering template 10, the raw material in the metering hole 11 will not leak into the gap between the discharge plate 20 and the metering template 10 when it falls into the discharge hole 21, resulting in high filling accuracy and high safety.

[0048] This application also provides a combined fireworks production line, which includes the fireworks charging assembly provided in the previous section. In this embodiment, the fireworks charging assembly is used for charging the outer tube of the combined fireworks, loading propellant into the outer tube.

[0049] The fireworks loading assembly provided in this application can be used for loading the inner tube of fireworks. The inner tube material can be quantitatively loaded into the quantitative holes on the quantitative template, and the material feeding control mechanism is used to control the material feeding through the quantitative holes. The rotating component is housed in the assembly groove on the upper surface of the material feeding plate, and the positions of the material feeding holes and quantitative holes correspond one-to-one. The upper surface of the material feeding plate and the lower surface of the quantitative template are closely fitted together, ensuring a one-to-one engagement between the material feeding holes and the quantitative holes. Thus, there is no gap between the material feeding plate and the quantitative template, and the material in the quantitative holes will not leak into the gap between the material feeding plate and the quantitative template when it falls into the feeding holes, resulting in high loading accuracy and high safety.

[0050] Therefore, the technical advantage of this application lies in providing an automated inner cylinder filling device with high filling accuracy and high safety. Furthermore, the fireworks filling assembly provided in this application also exhibits the aforementioned technical advantages when applied to the outer cylinder filling of combined fireworks.
