Description

Technical Field

[0001] The present application relates to the technical field of fireworks production equipment, and in particular to a production line for combined fireworks. Background Art

[0002] The launch tube of a combination firework is composed of multiple individual firework tubes. Currently, combination fireworks can be produced using automated production lines, with multiple loading devices deployed on the production line, such as a military-grade gunpowder loading device, a paper-sheet loading device, and an inner tube loading device. During production, the multiple loading devices on the production line load the fireworks multiple times. The military-grade gunpowder loading device is used to load the fireworks with military-grade gunpowder, the paper-sheet loading device is used to load the fireworks with paper, and the inner tube loading device is used to load the fireworks with inner tubes.

[0003] Paper-sheet loading equipment and inner-tube loading equipment often have different requirements for the angular orientation of the launch tubes. For example, to maximize paper tube utilization, the paper-sheet loading equipment requires the launch tubes on the conveyor line to be positioned at angle A; while the inner-tube loading equipment requires the launch tubes on the conveyor line to be positioned at angle B. Therefore, a single conveyor line with fixed delivery directions often cannot simultaneously meet the angular orientation requirements of both paper-sheet loading and inner-tube loading equipment.

DETAILED DESCRIPTION

[0041] The following are specific embodiments of the present application and, in conjunction with the accompanying drawings, further description of the technical solutions of the present application is provided, but the present application is not limited to these embodiments. In the following description, specific details such as specific configurations and components are provided solely to assist in a comprehensive understanding of the embodiments of the present application. Therefore, it should be clear to those skilled in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope of protection of the present application. In addition, for clarity and brevity, descriptions of known functions and configurations have been omitted.

[0042] It should be noted that, unless there is any conflict, the embodiments and features in the embodiments of this application can be combined with each other.

[0043] Multiple loading equipment are deployed on a production line for combination fireworks, such as a military gunpowder filling machine, a paper sheet filling machine, and an inner tube filling machine. During production, the various loading machines on the production line will load the fireworks bodies multiple times. The military gunpowder filling machine is used to load the fireworks bodies with military gunpowder, the paper sheet filling machine is used to load the fireworks bodies with paper sheets, and the inner tube filling machine is used to load the fireworks bodies with inner tubes. The paper sheet filling machine and the inner tube filling machine often have different requirements for the angular orientation of the launch tubes. For example, to maximize paper tube utilization, the paper sheet filling machine requires the launch tubes on the conveyor line to be positioned at angle A, while the inner tube filling machine requires the launch tubes on the conveyor line to be positioned at angle B. Therefore, a single conveyor line with fixed-direction delivery often cannot simultaneously meet the angular orientation requirements of both the paper sheet filling machine and the inner tube filling machine. To this end, the present application provides a production line for combined fireworks, which can adjust the angular direction of the launch tube unit between the inner tube filling assembly and the paper filling assembly, thereby simultaneously meeting the angular direction requirements of the inner tube filling assembly and the paper filling assembly for the launch tube.

[0044] refer to Figure 1 and Figure 2 The production line of combined fireworks includes a conveyor line 10, which conveys launch tube units 60 along a set conveying direction. Each launch tube unit is composed of one or more firework launch tubes; along the conveying direction of the conveyor line 10, a first paper sheet filling assembly 20, an inner tube filling assembly 30, and a second paper sheet filling assembly 40 are arranged in sequence; the first paper sheet filling assembly 20 is used for the first paper sheet filling of the firework launch tube; the inner tube filling assembly 30 is used for the inner tube filling of the firework launch tube; the second paper sheet filling assembly 40 is used for the second paper sheet filling of the firework launch tube; a first rotating assembly 50a is arranged between the first paper sheet filling assembly 20 and the inner tube filling assembly 30, and the first rotating assembly 50a can rotate to adjust the horizontal angle of the launch tube unit; a second rotating assembly 50b is arranged between the second paper sheet filling assembly 40 and the inner tube filling assembly 30, and the second rotating assembly 50b can rotate to adjust the horizontal angle of the launch tube unit.

[0045] When producing combination fireworks on a production line, the launch tube unit is transported forward along a conveyor line 10, passing through the first paper-filling assembly 20, the inner-tube-filling assembly 30, and the second paper-filling assembly 40, respectively, undergoing the first paper-filling, inner-tube-filling, and second paper-filling processes. A first rotating assembly 50a is positioned between the first paper-filling assembly 20 and the inner-tube-filling assembly 30. After the launch tube unit passes through the first paper-filling assembly 20, the first rotating assembly 50a adjusts the angle of the launch tube unit so that the angular orientation of the launch tube unit is aligned with the inner-tube-filling assembly 30. A second rotating assembly 50b is positioned between the second paper-filling assembly 40 and the inner-tube-filling assembly 30. After the launch tube unit passes through the inner-tube-filling assembly 30, the second rotating assembly 50b adjusts the angle of the launch tube unit so that the angular orientation of the launch tube unit is aligned with the second paper-filling assembly 40. Therefore, the above-mentioned first rotating component 50a and the second rotating component 50b can adjust the angular direction of the launching tube unit between the inner tube filling component and the paper sheet filling component, so as to simultaneously meet the requirements of the inner tube filling component and the paper sheet filling component for the angular direction of the launching tube.

[0046] refer to Figure 7 The launching tube unit 60 is composed of one or a group of launching tubes 61. Specifically, the launching tube unit 60 may include launching tubes 61 in the number of 1, 2, 3, 4, 5, 6, 7, 8, 9, ... Figure 7 A launching tube unit 60 is shown, which is composed of four launching tubes 61.

[0047] The launch tube unit 60 is equipped with multiple rows of launch holes. In one embodiment of the present application, the production line for combination fireworks features multiple inner tube loading assemblies 30 for loading multiple types of inner tubes into the launch tubes. Specifically, the multiple inner tube loading assemblies 30 are sequentially spaced at different locations along the conveyor line 10. The inner tube loading assemblies 30 are capable of delivering one row of inner tubes at a time to be loaded into a corresponding row of launch holes on the launch tube unit 60. As the conveyor line 10 operates, the launch tube units 60 on it move to the locations of the respective inner tube loading assemblies 30 for loading. Therefore, the multiple rows of launch holes on the launch tube unit can be aligned with the multiple inner tube loading assemblies 30 for loading and loading. When different types of inner tubes are loaded into each inner tube loading assembly, the launch tube unit (launch tube) can be flexibly loaded with a mixture of multiple types of inner tubes. In a specific embodiment, all inner barrel loading assemblies 30 can be simultaneously loaded and aligned with different launch barrel units; when each inner barrel loading assembly 30 is respectively loaded and aligned with a launch barrel unit at a different position on the conveyor line 10, each inner barrel loading assembly 30 is aligned with a different row of launch holes on the launch barrel unit.

[0048] In one embodiment of the present application, the conveying direction of the conveyor line 10 remains fixed between the first paper sheet loading assembly 20 and the second paper sheet loading assembly 40. The first rotating assembly 50a is used to rotate the launch tube unit from a first angular position to a second angular position, and the second rotating assembly 50b is used to rotate the launch tube unit from the second angular position to the first angular position. In one embodiment, the first angular position and the second angular position differ by 90 degrees.

[0049] The rotating assembly includes a first rotating assembly 50a and a second rotating assembly 50b. In one embodiment of the present application, the first rotating assembly 50a and the second rotating assembly 50b adopt the same structure. Figure 3-Figure 6 The first rotating assembly 50a and the second rotating assembly 50b each include a base 51, a first rotating member 52 and a second rotating member 53, and a rotation driving device 54, wherein the first rotating member 52 and the second rotating member 53 can act on the launching tube unit 60; the rotation driving device 54 is installed on the base 51; the rotation driving device 54 is used to drive the first rotating member 52 and the second rotating member 53 to move, so that the first rotating member 52 and the second rotating member 53 push the launching tube unit to rotate and adjust the horizontal angle. Furthermore, the first rotating member 52 is provided with a first rib 521 and a second rib 522, which are perpendicular to each other and form an L-shaped structure; the second rotating member 53 is provided with an intersecting third rib 531 and a fourth rib 532, which are perpendicular to each other and form an L-shaped structure; when the first rotating member 52 and the second rotating member 53 are restricted from entering the launching tube unit therebetween from the diagonal position, the rotation drive device 54 can drive the first rotating member 52 and the second rotating member 53 to push the launching tube unit to rotate and adjust the horizontal angle.

[0050] refer to Figure 5 The first rotating member 52 and the second rotating member 53 restrict the launch tube unit entering therebetween from the diagonal position. In this state, the first guard side 521, the second guard side 522, the third guard side 531, and the fourth guard side 532 respectively impose restrictions on the four sides of the launch tube unit 60. The first rotating member 52 and the second rotating member 53 can push the launch tube unit to rotate and adjust the horizontal angle.

[0051] In one embodiment of the present application, the first rotating assembly 50a and the second rotating assembly 50b further include a telescopic driving device 55; the telescopic driving device 55 is used to drive the first rotating member 52 to move up and down. Figure 3 When the telescopic driving device 55 drives the first rotating member 52 to move upward to a position higher than the launching tube unit, the launching tube unit on the conveyor line 10 can pass under the first rotating member 52 and enter or exit the space between the first rotating member 52 and the second rotating member 53. Figure 3In the state shown, the first rotating member 52 is higher than the position of the launching tube unit, and the launching tube unit can pass under the first rotating member 52 and enter the space between the first rotating member 52 and the second rotating member 53 (as shown in FIG. Figure 5 When the telescopic drive device 55 drives the first rotating member 52 to move downward to the height position where the launching tube unit is located, the first rotating member 52 and the second rotating member 53 restrict the launching tube unit from entering therebetween from the diagonal positions, thereby pushing the launching tube unit to rotate and adjust the horizontal angle.

[0052] During production line operation, the telescopic drive 55 drives the first rotating member 52 upward to a position above the launch tube units. The launch tube units on the conveyor line 10 pass under the first rotating member 52 and enter the space between the first rotating member 52 and the second rotating member 53. Next, the telescopic drive 55 drives the first rotating member 52 downward to the height of the launch tube units. The first and second rotating members 52 and 53 restrict the launch tube units from entering between them from diagonally opposite positions. Driven by the rotation drive 54, the launch tube units are rotated to adjust their horizontal angles from a first angular position to a second angular position. Finally, the telescopic drive 55 drives the first rotating member 52 upward to a position above the launch tube units. The launch tube units between the first and second rotating members 52 and 53 can pass under the first rotating member 52 and continue to move forward along the conveyor line 10.

[0053] In one embodiment of the present application, the rotation drive device 54 includes a rotating base 541, a rack structure 542, and a driving source 543; wherein the rotating base 541 is rotatably mounted on the base 51; a gear is provided on the rotating base 541; the first rotating member 52 and the second rotating member 53 are both connected to the rotating base 541; the rack structure 542 forms a meshing transmission relationship with the gear; the driving source 543 is mounted on the base 51; the driving source 543 is used to drive the rack structure 542 to move, so that the rack structure 542 drives the rotating base 541 to rotate. Furthermore, the rack structure 542 is slidably mounted on the base 51 and is limited to sliding in a fixed direction. When the driving source 543 can drive the rack structure 542 to move, the rack structure 542 drives the rotating base 541 to rotate through the meshing transmission relationship, and causes the first rotating member 52 and the second rotating member 53 to rotate synchronously.

[0054] In summary, in the production line of combined fireworks provided in the embodiment of the present application, a first paper filling assembly, an inner tube filling assembly, and a second paper filling assembly are arranged in sequence along the conveying direction of the conveyor line; a first rotating assembly is arranged between the first paper filling assembly and the inner tube filling assembly, and a second rotating assembly is arranged between the second paper filling assembly and the inner tube filling assembly; the first rotating assembly and the second rotating assembly are used to rotate and adjust the horizontal angle of the launching tube unit, and the angular direction of the launching tube unit can be adjusted between the inner tube filling assembly and the paper filling assembly, so as to simultaneously meet the angular direction requirements of the inner tube filling assembly and the paper filling assembly for the launching tube.
