Description

Technical Field

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

[0002] The inner tube of a firework contains bright beads, gunpowder, filler, and a priming agent. When ignited, these tubes create various effects, such as a dazzling display of colors and a variety of sounds. During the fireworks production process, the inner tubes are loaded into the outer tube of the firework body. Firework inner tubes are categorized into different types based on the desired effect (e.g., color, sound). Currently, most inner tube loading equipment has only one hopper and can only load one type of inner tube. To load multiple types of firework inner tubes, multiple inner tube loading devices are required, each for a single type. This results in low integration, high costs, and inefficient loading.

[0003] Most current fireworks loading equipment uses a transfer mold. The loading assembly first loads the inner tube into the transfer mold, which then transfers the inner tube to the launch tube. This involves numerous steps and a complex mechanical structure. Furthermore, the loading efficiency of current fireworks loading equipment still needs to be improved. Utility Model Content

DETAILED DESCRIPTION

[0032] 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.

[0033] 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.

[0034] In the inner tube loading equipment for combination fireworks, a transfer module is usually provided; the transfer module is provided with loading holes aligned with the holes of the firework launch tube. When the equipment is in operation, the inner tube pushed out by the loading assembly is first loaded into the loading hole of the transfer module, and then the firework launch tube is loaded by the transfer module. This type of equipment has many operation processes and a complex mechanical structure. To this end, the present application provides a positioning and loading line for a firework launch tube, which includes a conveying mechanism, multiple loading assemblies, and multiple precise positioning assemblies; the conveying mechanism is used to convey the launch tube along a set conveying direction; multiple loading assemblies are sequentially arranged at different positions of the conveying mechanism along the conveying direction; multiple precise positioning assemblies are sequentially arranged at different positions of the conveying mechanism along the conveying direction; the precise positioning assemblies correspond one-to-one with the loading assemblies; the precise positioning assemblies are used to align the loading unit consisting of one or a group of launch tubes on the conveying mechanism with the corresponding loading assembly. This positioning and loading line directly loads the fireworks launch tubes. The launch tubes are positioned by a conveyor mechanism, and a precise positioning assembly is installed on top of the conveyor mechanism to improve the positioning accuracy of the launch tubes, thereby achieving more precise positioning between the launch tubes and the loading assembly. The following is a detailed description of this positioning and loading line with reference to the accompanying drawings.

[0035] refer to Figure 1-Figure 2 The positioning and loading line includes a conveying mechanism 10, multiple loading assemblies 20, and multiple precise positioning assemblies 30. The conveying mechanism 10 is used to convey the launch tubes along a set conveying direction; the multiple loading assemblies 20 are sequentially arranged at different positions on the conveying mechanism 10 along the conveying direction; the multiple precise positioning assemblies 30 are sequentially arranged at different positions on the conveying mechanism 10 along the conveying direction; the precise positioning assemblies 30 correspond one-to-one with the loading assemblies 20; and the precise positioning assemblies 30 are used to align the loading unit 60, consisting of one or a group of launch tubes 61, on the conveying mechanism 10 with the corresponding loading assembly 20 for loading.

[0036] The loading unit 60 is composed of one or a group of launching tubes 61. Specifically, the loading unit 60 may include launching tubes 61 in the number of 1, 2, 3, 4, 5, 6, 7, 8, 9, ... Figure 3 A loading unit 60 is shown, which is composed of four launching tubes 61. When the loading unit 60 is in operation, the multiple loading units 60 thereon move along a set conveying direction.

[0037] The loading unit 60 is equipped with multiple rows of firing holes 62. Multiple loading assemblies 20 are sequentially spaced apart at different locations along the conveying direction on the conveyor mechanism 10. Each loading assembly 20 can deliver a row of inner barrels at a time, which are then loaded into the corresponding row of firing holes 62 on the loading unit 60. As the conveyor mechanism 10 operates, the loading unit 60 on it moves to the location of each loading assembly 20. The precise positioning assembly 30 aligns the loading unit 60 with the corresponding loading assembly 20 for precise blanking and loading. Therefore, the multiple rows of firing holes 62 on the loading unit 60 can be aligned with multiple loading assemblies 20 for blanking and loading. When different types of inner barrels are placed in each loading assembly, the loading unit (launching barrel) can be flexibly loaded with a mixture of multiple types of inner barrels. On the other hand, the position of the launch tube is transported by a conveying mechanism, and a precise positioning component is set on the basis of the conveying mechanism to improve the positioning accuracy of the launch tube, so that the loading positioning between the launch tube and the loading component can be achieved more accurately.

[0038] It should be noted that the loading assembly is a conventional component of the fireworks inner tube loading equipment. Its main part is the hopper for placing the inner tubes, and is equipped with a pushing mechanism that can deliver a row of inner tubes at a time to be loaded into a row of holes on the transfer module or loading unit (launch tube).

[0039] For example, the loading unit 60 is provided with N rows of firing apertures 62. The first row of firing apertures 62 is loaded by the first loading assembly 20, the second row of firing apertures 62 is loaded by the second loading assembly 20, and so on. The Nth row of firing apertures 62 is loaded by the Nth loading assembly 20. If the inner barrels contained in the various loading assemblies 20 are of different types, the loading unit (launch barrel) will accordingly contain multiple types of inner barrels after loading is complete.

[0040] In one embodiment of the present application, all precise positioning components 30 can be linked to enable all loading components 20 to be simultaneously aligned with different loading units 60. With this structural design, multiple loading components 20 can be loaded simultaneously, thereby achieving higher loading efficiency. Furthermore, when each loading component 20 is respectively aligned with the loading units 60 at different positions on the conveying mechanism 10, each loading component 20 is aligned with different rows of emission holes 62 on the loading unit 60. In a specific embodiment, when each loading component 20 is respectively aligned with the loading units 60 at different positions on the conveying mechanism 10, based on the conveying direction of the conveying mechanism 10, when the i-th loading component 20 is aligned with the j-th row of emission holes 62 on the loading unit 60, the i+1-th loading component 20 is aligned with the j+1-th row of emission holes 62 on the loading unit 60 at the next position.

[0041] For example, the multiple loading assemblies are sequentially designated as loading assembly A1, loading assembly A2, ..., loading assembly Ak, and the multiple rows of firing apertures on the loading unit (launching tube) are sequentially designated as the first row of firing apertures, the second row of firing apertures, ..., the kth row of firing apertures, ...; when each loading assembly is aligned with a loading unit (launching tube) at a different position on the conveying mechanism, loading assembly A1 is aligned with the first row of firing apertures on the loading unit (launching tube), loading assembly A2 is aligned with the second row of firing apertures on the loading unit (launching tube), ..., and loading assembly Ak is aligned with the kth row of firing apertures on the loading unit (launching tube). In one specific embodiment, during loading, the first loading assembly is aligned with the first row of firing apertures on the lower loading unit (launching tube), the second loading assembly is aligned with the second row of firing apertures on the lower loading unit (launching tube), ...; and as the conveying mechanism operates, each row of firing apertures on the loading unit (launching tube) is sequentially filled by each loading assembly.

[0042] refer to Figure 4-Figure 6 In one embodiment of the present application, the precise positioning assembly 30 includes a guide structure 31, a movable frame 32, a first driving element 33, and a limiting mechanism. The extending direction of the guide structure 31 is consistent with the conveying direction of the conveying mechanism 10; the movable frame 32 is mounted on the guide structure 31 and is limited to sliding along the extending direction of the guide structure 31; the first driving element 33 is used to drive the movable frame 32 to move along the extending direction of the guide structure 31; and the limiting mechanism is mounted on the movable frame 32 and is used to impose restrictions on the loading unit 60 on the conveying mechanism 10 so that the loading unit 60 and the movable frame 32 move synchronously, or to remove the restrictions so that the loading unit 60 can move with the conveying mechanism 10.

[0043] As the conveying mechanism 10 operates, the loading units 60 thereon are able to move to the locations of the respective loading assemblies 20. When a loading unit 60 moves to the location of a loading assembly 20, the corresponding precise positioning assembly's limiting mechanism constrains the loading unit 60 to maintain synchronous movement with the mobile frame 32. Driven by the first drive element 33, the mobile frame 32 moves and adjusts along the extension direction of the guide structure 31 to precisely align the loading unit 60 with the corresponding loading assembly 20. It should be understood that the arrangement of a precise positioning assembly 30 on the basis of the conveying mechanism 10 allows for more precise loading and positioning of the loading unit (launching tube), thereby improving positioning accuracy.

[0044] In one embodiment of the present application, the limiting mechanism includes two action mechanisms 34; the two action mechanisms 34 are respectively arranged on both sides of the conveying mechanism 10, and can clamp the loading unit 60 from both sides so that the loading unit 60 and the moving frame 32 can move synchronously. Furthermore, the action mechanisms 34 each include a limiting frame 341 and a second driving element 342, wherein the limiting frame 341 includes a first limiting member 3411, a second limiting member 3412, and a transverse limiting member 3413; the first limiting member 3411 and the second limiting member 3412 are arranged in front of and behind the conveying mechanism 10 and are parallel to each other; the transverse limiting member 3413 is perpendicular to the first limiting member 3411 and the second limiting member 3412, and is respectively connected to the first limiting member 3411 and the second limiting member 3412, thereby forming a recess 3414 on the inner side facing the conveying mechanism 10 that is adapted to the contour of the loading unit 60. The second driving element 342 is used to drive the limiting frame 341 to move, so that the notch 3414 of the limiting frame 341 is combined with the filling unit 60 to limit the filling unit 60, or to separate the limiting frame 341 from the filling unit 60 to allow the filling unit 60 to move with the conveying mechanism 10. Figure 4 In the illustrated structure, the notches 3414 of the limiting frames 341 of the action mechanisms 34 on both sides engage with the loading unit 60, restraining the loading unit 60 and thereby enabling the loading unit 60 to move synchronously with the moving frame 32. When the limiting frames 341 are separated from the loading unit 60, the loading unit 60 can move with the conveying mechanism 10.

[0045] In one embodiment of the present application, the limiting mechanism further includes a blocking mechanism 40, which is used to block the loading unit 60 on the conveying mechanism 10, so that the limiting mechanism can restrict the loading unit 60 in a blocked state. Furthermore, the blocking mechanism 40 includes a blocking member 41 and a third driving element 42; the third driving element 42 is used to drive the blocking member 41 so that the blocking member 41 can block the loading unit 60 on the conveying mechanism 10, or remove the blocking of the loading unit 60.

[0046] In one embodiment of the present application, the mobile racks 32 of adjacent precise positioning assemblies 30 are connected together by a connector 50, so that the mobile racks 32 of all precise positioning assemblies 30 can move synchronously. Figure 1 In the structure shown, the moving frame 32 of each precise positioning assembly 30 is driven by a first driving element 33 . Therefore, the first driving element 33 of each precise positioning assembly 30 may refer to the same first driving element 33 .

[0047] In addition, it should be noted that the first driving element, the second driving element, and the third driving element can be configured as various types of driving devices, such as electric devices and pneumatic devices, and can be specifically configured as cylinders.

[0048] The present application also provides a combined fireworks production device, comprising the aforementioned positioning and loading line for fireworks launch tubes. The positioning and loading line includes a conveying mechanism, multiple loading assemblies, and multiple precise positioning assemblies. The conveying mechanism is used to transport the launch tubes along a predetermined conveying direction. Multiple loading assemblies are sequentially spaced apart at different positions on the conveying mechanism along the conveying direction. Multiple precise positioning assemblies are sequentially spaced apart at different positions on the conveying mechanism along the conveying direction. The precise positioning assemblies correspond one-to-one with the loading assemblies. The precise positioning assemblies are used to align a loading unit consisting of one or a group of launch tubes on the conveying mechanism with the corresponding loading assemblies. The positioning and loading line directly loads the fireworks launch tubes. The position of the launch tubes is determined by the conveying mechanism. Precise positioning assemblies are provided on top of the conveying mechanism to improve the positioning accuracy of the launch tubes, thereby enabling more precise positioning between the launch tubes and the loading assemblies.
