Description

Technical Field

[0001] This invention belongs to the field of fireworks production technology, and in particular relates to a fireworks inner tube installation production line and a fireworks assembly production line. Background Technology

[0002] Fireworks, widely used in traditional festivals and entertainment activities, typically consist of an outer tube and multiple inner tubes (also known as effect tubes). The inner tubes are filled with functional materials such as bright beads, gunpowder, igniters, and fillers, and are key units for achieving visual and auditory effects, possessing dangerous characteristics such as flammability and explosiveness. In current fireworks production processes, the assembly of the inner tubes, especially the accurate and stable installation into the outer tube, still relies primarily on manual operation or mechanical pushing structures. Chinese patent CN222703930U discloses a fireworks inner tube discharging device that uses a material trough, a pusher, an elastic element, and a discharge slide for feeding. However, this method relies solely on gravity to discharge the material, offering no guidance on the orientation of the inner tubes, making them prone to misalignment and jamming. Furthermore, given that the inner tubes themselves are flammable and explosive, the gravity-feeding method presents inherent safety hazards. Furthermore, in the existing technology, the production of multi-colored fireworks often requires operators to manually fill the inner tubes of the fireworks with the corresponding colors into the outer tubes. This is not only labor-intensive, but also poses a serious threat to the personal safety of operators due to the possibility of accidental explosions during fireworks production.

[0003] Therefore, how to provide a device that can supply raw materials for the inner tube of fireworks in a directional, orderly, stable, efficient and safe manner, and realize the automated assembly of the inner tube of fireworks in the outer tube of fireworks, and how to apply it to the production of multi-colored fireworks, are technical problems that urgently need to be solved in this field. Summary of the Invention

[0005] The feeding assembly is located on one side of the conveying assembly and includes: a feeding turntable for carrying the inner tube of the fireworks, and a first baffle plate arranged around the edge of the feeding turntable. The first baffle plate is provided with a discharge port for horizontally conveying the inner tube of the fireworks to the conveying assembly.

[0006] The conveying assembly includes a conveyor belt, feeding channels arranged at intervals along the conveying direction of the conveyor belt, and an inner cylinder positioning component located at the end of the feeding channel; the feeding channel corresponds one-to-one with the discharge port of the feeding assembly.

[0007] The flip-grip assembly, located at the end of the conveyor assembly, is used to grab the inner cylinder of the firework from the inner cylinder positioning component and install it into the outer cylinder of the firework.

[0008] Furthermore, the discharge port is provided with a flow guide channel formed by a flow guide plate, which extends toward and connects with the feeding channel.

[0009] Furthermore, the feeding assembly also includes an inner cylinder deflector;

[0010] The first end of the inner cylinder deflector is located in the center of the feeding turntable, and the second end extends toward the first baffle.

[0011] The minimum distance between the second end of the inner tube lever and the first baffle is not less than the diameter of the inner tube of the firework.

[0012] Furthermore, the inner cylinder paddle includes a straight segment and an arc segment connected in sequence;

[0013] The straight section is located in the center of the feeding turntable and is made of rigid material;

[0014] The arc-shaped segment is naturally connected to the straight segment at one end, and the other end is bent along the rotation direction of the feeding component. It is made of flexible material.

[0015] Furthermore, the feeding assembly also includes a mounting plate;

[0016] The mounting plate is set along the diameter of the feeding turntable and straddles the first baffle.

[0017] The mounting plate has a mounting groove in the middle, and the first end of the inner cylinder lever can be moved and adjusted along the direction of the mounting groove and its position can be fixed.

[0018] Furthermore, the feeding assembly also includes a second baffle extending from the discharge port to the feeding turntable;

[0019] The second baffle is arranged at equal intervals with the first baffle to form a feed channel that is connected to the guide channel.

[0020] Furthermore, it also includes a material distribution component disposed on the side of the conveying component;

[0021] The material distribution assembly is located before the inner cylinder positioning component and includes: an inner cylinder blocking component and an inner cylinder separating component;

[0022] The inner cylinder blocking component is located between the inner cylinder positioning component and the inner cylinder separating component. Both the inner cylinder blocking component and the inner cylinder separating component can be telescopically installed on the side of the feeding channel.

[0023] Furthermore, the distance between the inner tube blocking component and the inner tube separating component is greater than 1 / 2 times the diameter of the inner tube of the fireworks, but less than 1 time the diameter of the inner tube of the fireworks.

[0024] Furthermore, a separation expansion groove for accommodating the expansion end of the inner cylinder separator is provided along the vertical direction of the feeding channel on the side of the feeding channel.

[0025] Furthermore, on the side near the feeding channel, the inner cylinder positioning component is provided with an arc groove that is the same number as the feeding channel, and the shape of the arc groove is adapted to the outer shape of the firework's inner cylinder.

[0026] Furthermore, the flipping and gripping assembly includes: an inner cylinder positioning detector, a robotic arm connected to the inner cylinder positioning detector, and grippers mounted on the robotic arm;

[0027] The inner tube positioning detector, located at the front end of the inner tube positioning component, is used to detect the positioning status of the fireworks' inner tube.

[0028] The grippers are equipped with multiple retractable gripping holes corresponding to the position of the feeding channel, for gripping the inner tube of the fireworks.

[0029] The robotic arm is positioned above the inner cylinder positioning component and can drive the grippers to rotate, flip, and translate, so as to accurately insert the inner cylinder into the outer cylinder of the fireworks.

[0033] A fireworks assembly line, including any of the above-mentioned fireworks inner tube installation production lines.

[0034] This embodiment provides a fireworks inner tube installation production line. In use, operators or a conveying device first place bulk fireworks inner tubes (with the lead wire facing upwards when in the feeding assembly, but downwards during installation to prevent the lead wire from igniting due to friction and causing an explosion) onto the feeding turntable of the feeding assembly. The turntable rotates continuously, causing the inner tubes to align orderly along its edge under centrifugal force. The fireworks inner tubes pass through the feeding port and enter the conveyor belt and feeding channels. The feeding channels are spaced along the conveying direction to maintain spacing between the inner tubes during transport, preventing friction. An inner tube positioning component is located at the end of the feeding channel for precise positioning. Subsequently, a flipping gripping assembly picks up the fireworks inner tube from the positioning component, flips it so the lead wire faces downwards, and installs it into the fireworks outer tube. The feeding turntable, combined with a lever and a first baffle, enables the directional arrangement and stable, orderly release of the firework inner tubes. These tubes enter the feeding channel horizontally, avoiding the chaotic posture, jamming, and safety hazards caused by traditional gravity-feeding. This improves the stability, continuity, and safety of the feeding process, further enhancing the automation level of the firework inner tube installation production line. For example, multiple feeding components are arranged in parallel, each containing a different colored firework inner tube. The rotating feeding turntable guides them into their respective feeding channels, where they are then installed onto the firework outer tube, achieving automated manufacturing of multi-colored fireworks. Compared to existing manual inner tube filling methods, this significantly reduces labor intensity and minimizes personal injury from accidental explosions during firework production. Furthermore, the parallel arrangement of the feeding components results in a compact structure, greatly reducing the floor space required. In summary, this application provides a firework inner tube installation production line that provides a directional, orderly, stable, efficient, and safe supply of firework inner tube materials, enabling automated assembly of the inner tubes onto the outer tube, and is suitable for multi-colored firework production.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

Those skilled in the art will understand that anything that does not violate the inventive concept and does not contradict the inventive points should be included within the scope of protection of the present invention.

[0043] This invention provides a fireworks inner tube installation production line, referenced Figure 1 and Figure 2 It includes: a feeding component 1, a conveying component 2, and a flipping and gripping component 3 arranged in sequence;

[0044] The feeding assembly 1 is located on one side of the conveying assembly 2 and includes: a feeding turntable 11 for carrying the inner tube of the fireworks, and a first baffle 13 arranged around the edge of the feeding turntable 11. The first baffle 13 is provided with an outlet 13a for horizontally conveying the inner tube of the fireworks to the conveying assembly 2.

[0045] The conveying assembly 2 includes: a conveyor belt 23, and feeding channels 21 arranged at intervals along the conveying direction of the conveyor belt 23, and an inner cylinder positioning member 22 located at the end of the feeding channel 21; the feeding channel 21 corresponds one-to-one with the discharge port 13a of the feeding assembly 1.

[0046] The flipping and gripping assembly 3 is located at the end of the conveying assembly 2 and is used to grip the inner tube of the firework on the inner tube positioning part 22 and install it into the outer tube of the firework.

[0047] This embodiment provides a fireworks inner tube installation production line. In use, operators or a conveying device first place bulk fireworks inner tubes (with the lead wire facing upwards when in the feeding assembly, but downwards during installation to prevent the lead wire from igniting due to friction and causing an explosion) onto the feeding turntable of the feeding assembly. The turntable rotates continuously, causing the inner tubes to align orderly along its edge under centrifugal force. The fireworks inner tubes pass through the feeding port and enter the conveyor belt and feeding channels. The feeding channels are spaced apart along the conveying direction to maintain spacing between the inner tubes during transport, preventing friction. An inner tube positioning component is located at the end of the feeding channel for precise positioning. Subsequently, a flipping gripping assembly picks up the fireworks inner tube from the positioning component, flipping it from lead wire upwards to lead wire downwards, and installing it into the fireworks outer tube. The feeding turntable, combined with a lever and a first baffle, enables the directional arrangement and stable, orderly release of the firework inner tubes. Entering the feeding channel horizontally avoids the chaotic posture, jamming, and safety hazards caused by traditional gravity-feeding, thus improving the stability, continuity, and safety of the feeding process and further enhancing the automation level of the firework inner tube installation production line. For example, multiple feeding components are arranged in parallel, each containing a different colored firework inner tube. The rotation of the feeding turntable sends them into their respective feeding channels in parallel. A flipping gripping component rotates the inner tube 180° and then places them sequentially into the outer firework tube according to their designated color and position, achieving automated manufacturing of multi-colored fireworks. Compared to existing manual inner tube filling methods, this significantly reduces labor intensity and minimizes personal injury from accidental explosions during firework production. Furthermore, the parallel arrangement of the feeding components results in a compact structure, greatly reducing the floor space required. In summary, this application provides a fireworks inner tube installation production line that can supply fireworks inner tube raw materials in a directional, orderly, stable, efficient, and safe manner, realize the automated assembly of fireworks inner tubes into fireworks outer tubes, and is applicable to the production of fireworks with multiple colors.

[0048] Preferably, the discharge port 13a is provided with a guide channel 17 formed by a guide plate, the guide channel 17 extends towards the feeding channel and communicates with the feeding channel 21. By adding a guide channel between the discharge port and the feeding channel, the displacement, jamming or scattering of the firework inner tube is effectively avoided, ensuring that the firework inner tube enters the feeding channel smoothly in the set direction, and improving the feeding efficiency.

[0049] Preferred, Reference Figure 1 and Figure 2 The feeding assembly 1 also includes an inner cylinder deflector 12;

[0050] The first end of the inner cylinder deflector 12 is located in the center of the feeding turntable 11, and the second end extends toward the first baffle 13;

[0051] The minimum distance between the second end of the inner tube lever 12 and the first baffle 13 is not less than the diameter of the inner tube of the firework.

[0052] In this embodiment, the first end of the inner tube deflector is fixed to the center of the feeding turntable, and the second end of the deflector extends towards the first baffle. As the feeding turntable rotates, some of the firework inner tubes are arranged sequentially on the edge of the feeding turntable under the action of centrifugal force. The remaining firework inner tubes that are not immediately arranged are guided to move towards the edge of the feeding turntable by the fixed inner tube deflector. When the firework inner tubes rotate with the turntable to the second end of the inner tube deflector, a certain distance is maintained between the second end of the inner tube deflector and the first baffle. This distance is not less than the diameter of the firework inner tube, ensuring that the firework inner tubes can pass smoothly through the gap, thereby achieving orderly separation and conveying of the firework inner tubes. The rotation of the feeding turntable pushes the firework inner tubes to slide out of the turntable one by one, pass through the discharge port on the first baffle and enter the feeding channel, ensuring the directional and stable conveying of the firework inner tubes. More preferably, the distance between the inner tube deflector and the first baffle is 1 to 1.5 times the diameter of the firework inner tube.

[0053] Preferred, Reference Figure 2 The inner cylinder lever 12 includes: a straight segment 12a and an arc segment 12b connected in sequence;

[0054] The straight section 12a is located in the center of the feeding turntable 11 and is made of rigid material;

[0055] The arc-shaped segment 12b extends toward the first baffle 13 and is made of a flexible material.

[0056] In this embodiment, the inner tube lever comprises a straight segment and an arc segment connected in sequence. The straight segment, located at the center of the feeding turntable, is made of rigid material and possesses excellent structural rigidity and guiding support capabilities, effectively propelling the inner tube of the fireworks to move orderly towards the edge of the feeding tray. The arc segment, made of flexible material, extends to a position near the first baffle. This arc segment not only provides flexible buffering, allowing for moderate deformation upon contact with the inner tube of the fireworks to prevent damage from rigid collisions and improve feeding safety, but also utilizes the curved structure of the arc segment to form a smooth transition curve, guiding the inner tube of the fireworks to slide naturally along the lever's arc path to the edge of the feeding turntable, and then moving to the outlet under the rotation of the feeding turntable, enhancing the smoothness and continuity of the feeding process. Specifically, the straight segments use thicker stainless steel sheets or other rigid materials, such as aluminum alloys, carbon steel, engineering plastics, etc.; the curved segments use thinner stainless steel sheets, or other flexible materials with flexible transitions, such as spring steel, polyurethane, composite plastics, etc., which can undergo soft deformation and return to their original position; the straight segments and flexible segments are joined together by welding.

[0057] Preferred, Reference Figure 2 The arc-shaped segment 12b of the inner tube lever 121 is naturally connected to the straight segment 12a at one end, and bent along the rotation direction of the feeding assembly 1 at the other end. By naturally connecting the arc-shaped segment of the inner tube lever to the straight segment, the overall structure of the inner tube lever is smoothly transitioned, which is conducive to the smooth movement of the inner tube under the guidance of the lever. The other end of the arc-shaped segment is bent along the rotation direction of the feeding assembly, forming a guiding structure that allows the inner tube of the fireworks to be guided between the inner tube lever and the first baffle under the action of centrifugal force, further improving the arrangement order and conveying stability of the inner tube of the fireworks.

[0058] Preferred, Reference Figure 2 The feeding assembly 1 also includes a mounting plate 14;

[0059] Mounting plate 14 is arranged along the diameter direction of feeding turntable 11 and spans across the first baffle 13;

[0060] The mounting plate 14 has a mounting groove in the middle, and the first end of the inner cylinder lever 12 can be moved and adjusted and fixed in position along the mounting groove.

[0061] In this embodiment, the mounting plate is arranged along the diameter direction of the feeding turntable and straddles the first baffle. The first end of the inner tube lever can be moved and adjusted along the mounting groove and its position can be fixed, thereby realizing flexible adjustment of the position of the inner tube lever, effectively controlling the guiding path of the fireworks inner tube, as well as the size of the distance between the inner tube lever and the first baffle, and improving the applicability of the device. For example, the first end of the inner tube lever is provided with a bolt and nut corresponding to the mounting groove. Loosening the nut allows the inner tube lever to move on the mounting groove, and tightening the nut fixes the inner tube lever. The structure is simple and easy to implement.

[0062] Preferred, Reference Figure 1 and Figure 2 The feeding assembly 1 also includes a second baffle 15 extending from the discharge port 13a to the feeding turntable;

[0063] The second baffle 15 is arranged at equal intervals with the first baffle 13 to form a feed channel 16 that is connected to the guide channel 17.

[0064] In this embodiment, the second baffle is arranged at equal intervals with the first baffle to form a feeding channel that communicates with the guide channel. This limits the movement path of the inner firework tube on the edge of the turntable, enabling directional guidance of the inner firework tubes distributed on the edge of the feeding turntable. This ensures that the inner firework tubes move in a fixed sequence along the "edge of the feeding turntable - feeding channel - guide channel - feeding channel", further improving the stability and accuracy of feeding and conveying the inner firework tubes.

[0065] More preferably, the distance between the second baffle and the first baffle is greater than one times the diameter of the inner tube of the firework, but less than two times the diameter of the inner tube. This ensures that the inner tube can pass smoothly through the feeding channel while effectively preventing lateral displacement or accumulation of the inner tube due to excessive channel width. By controlling the baffle distance, the inner tube can be stably and orderly conveyed between the turntable and the feeding channel, improving the conveying efficiency and automation level of the assembly, and ensuring the continuity and stability of the entire production line.

[0066] Preferred, Reference Figure 3 The fireworks inner tube installation production line also includes a material distribution component 4 located on the side of the conveying component 2;

[0067] The material distribution assembly 4 is positioned before the inner cylinder positioning member 22 and includes: an inner cylinder blocking member 41 and an inner cylinder separating member 42;

[0068] Both the inner cylinder blocking component and the inner cylinder separating component can be telescopically installed on the side of the feeding channel. The distance between the two is greater than 1 / 2 times the diameter of the inner cylinder of the fireworks and less than 1 time the diameter of the inner cylinder of the fireworks.

[0069] The inner cylinder blocking part 41 is located between the inner cylinder positioning part 22 and the inner cylinder separating part 42.

[0070] In this embodiment, the material distribution component is located at the end of the conveying component, before the inner cylinder positioning component, and includes an inner cylinder blocking component and an inner cylinder separating component. In use, firstly, the telescopic end of the inner cylinder blocking component extends to block the firework inner cylinders moving forward in the feeding channel, preventing multiple inner cylinders from entering the inner cylinder positioning component simultaneously. Then, the feeding channel pauses, the telescopic end of the inner cylinder blocking component retracts, and the telescopic end of the inner cylinder separating component extends. Utilizing the reasonable distance between the separating component and the inner cylinder positioning component, the telescopic end of the separating component directly presses against the side wall of the firework inner cylinder, squeezing out the foremost firework inner cylinder individually and separating it from the firework inner cylinders behind it in the channel. Next, the feeding channel continues to operate, delivering the separated firework inner cylinders to the positioning position of the inner cylinder positioning component; simultaneously, the inner cylinder blocking component extends again, and the telescopic end of the inner cylinder separating component retracts. The firework inner cylinders move forward in the feeding channel, blocked by the inner cylinder blocking component, completing one complete material distribution operation. This cyclical operation achieves the one-to-one and stable distribution of the inner tubes of fireworks. Through the intermittent action and extension control of the inner tube separator and the inner tube blocking component, the automation level and cycle efficiency of the entire assembly line are effectively improved. It is particularly suitable for the safe distribution and processing of flammable and explosive materials such as the inner tubes of fireworks.

[0071] More preferably, the distance between the inner cylinder blocking component and the inner cylinder separating component is greater than 1 / 2 times the diameter of the firework's inner cylinder and less than 1 times the diameter of the firework's inner cylinder. The telescopic end of the inner cylinder separating component directly presses against the side wall of the firework's inner cylinder, squeezing out the frontmost firework's inner cylinder individually and separating it from the firework's inner cylinder behind it in the channel, achieving a better separation effect of the firework's inner cylinder.

[0072] More preferably, both the inner cylinder blocking component and the inner cylinder separating component are driven by telescopic cylinders, with telescopic rods at their telescopic ends. Each telescopic cylinder is symmetrically installed in pairs on both sides of the spaced-apart feeding channels to simultaneously block and separate the inner cylinders of the fireworks in multiple feeding channels, achieving batch and uniform material distribution control and significantly improving production cycle time. More preferably, the end of the telescopic rod of the inner cylinder separating component is machined into a hemispherical shape to reduce localized pressure when in contact with the side wall of the inner cylinder of the fireworks. This allows for lateral compression and quantitative separation without damaging the inner cylinder, reducing jamming and impact on the inner cylinder and effectively improving safety during the installation process.

[0073] More preferably, refer to Figure 1 , Figure 3 and Figure 4 A separation and expansion groove 42a is provided along the side of the feeding channel 21, perpendicular to the feeding channel 21, to accommodate the telescopic end of the inner cylinder separator 42. This further improves the compactness of the device layout, reduces the area occupied by the device, and improves the telescopic separation effect of the inner cylinder separator.

[0074] More preferably, on the side near the feeding channel, the inner cylinder positioning component is provided with an arc groove with the same number of feeding channels. The shape of the arc groove is adapted to the shape of the inner cylinder of the firework, which can stably support and accurately position the inner cylinder, ensuring that the inner cylinder maintains the correct position at the end of the conveying component, providing reliable support for subsequent flipping and material grabbing, further improving assembly accuracy and production efficiency, and realizing automated and efficient installation of the inner cylinder of the firework.

[0075] Preferred, Reference Figure 1 and Figure 3 The flipping and gripping assembly 3 includes: an inner cylinder positioning detector 31, a robotic arm connected to the inner cylinder positioning detector 31, and grippers mounted on the robotic arm;

[0076] The inner tube positioning detector 31 is located at the front end of the inner tube positioning component 22 and is used to detect the positioning status of the inner tube of the fireworks.

[0077] The gripper is equipped with multiple retractable gripping holes corresponding to the position of the feeding channel 21, for gripping the inner tube of the fireworks;

[0078] The robotic arm is positioned above the inner cylinder positioning component 22 and can drive the grippers to rotate, flip, and translate, so as to accurately insert the inner cylinder into the outer cylinder of the fireworks.

[0079] In this embodiment, the flipping and gripping assembly uses an inner cylinder positioning detector to detect the position of the fireworks' inner cylinder in real time, ensuring that the inner cylinder accurately abuts against the inner cylinder positioning component and transmitting the position information to the robotic arm. The robotic arm's grippers are equipped with retractable gripping holes corresponding to the feeding channel, allowing for stable and efficient gripping of the fireworks' inner cylinder from the inner cylinder positioning component. The robotic arm's rotation, flipping, and translation functions enable the inner cylinder to be precisely inserted into the outer cylinder, ensuring automation and efficiency in the assembly process, while reducing manual intervention and improving the overall safety and production efficiency of the production line.

[0080] Example, reference Figure 1 The inner tube positioning detector 31 is a set of through-beam optical fibers symmetrically arranged on both sides of the transmission component 2. It detects whether the inner tube of the firework is accurately positioned by blocking the beam, achieving high-precision positioning and monitoring of the inner tube. This effectively ensures the timing and accuracy of the gripper's grasping action on the robotic arm. For example, the robotic arm employs a multi-axis linkage mechanism (e.g., a four-axis robot) design, including linear guideways for translational movement, rotary joints for rotational movement, and a flipping mechanism for flipping the gripper. This allows the robotic arm to move flexibly in multiple degrees of freedom, precisely adjusting the position and orientation of the gripper to ensure stable grasping and accurate assembly of the inner tube of the firework. This significantly improves the automation level of the inner tube installation, enabling unmanned assembly and significantly improving the safety and production efficiency of fireworks production.

[0081] Preferred, Reference Figure 1The fireworks inner tube installation production line also includes: an outer tube conveying assembly 4 and a vision assembly 5;

[0082] The outer cylinder conveying assembly 4 is located below the tilting and grabbing assembly 3 and is used to receive and convey the outer cylinder of the fireworks;

[0083] The vision component 5 is positioned above the outer cylinder conveying component 4 and connected to the flipping and gripping component 3, and is used to guide the flipping and gripping component 3 to install the inner cylinder of the fireworks onto the outer cylinder of the fireworks.

[0084] In this embodiment, by adding an outer cylinder conveying component, stable conveying of the fireworks outer cylinder is achieved, ensuring the continuity and reliability of the assembly position. By adding a vision component, the positional relationship of the installation holes of the fireworks outer cylinder can be monitored in real time with precision, providing accurate assembly guidance for the flipping and gripping component, significantly improving the accuracy and success rate of inner cylinder assembly. The overall system realizes automated, intelligent, and unmanned assembly of the fireworks inner and outer cylinders, improving production efficiency, reducing the risk of manual operation, and enhancing the safety and stability of the assembly process. Utilizing a robotic arm and vision component, material handling, conveying, blocking and sorting, gripping and flipping, and fireworks inner cylinder filling are automatically completed. The structure is simple and compact, easy to maintain, and can greatly improve the automation level of fireworks inner cylinder installation and reduce the failure rate. At the same time, it reduces the installation deviation of the fireworks inner cylinder caused by lateral misalignment due to processing errors during the production of fireworks outer cylinders. It is worth noting that this invention provides a fireworks inner cylinder installation production line, in which the specific timing actions, signal transmission methods, visual detection algorithms, and control methods of the material distribution component, flipping and gripping component, and vision component can all be implemented by programmable logic devices such as PLCs or existing technologies, and will not be elaborated here.

[0086] In this implementation, a fireworks assembly line is presented, which integrates any of the above-mentioned fireworks inner tube installation production lines. It realizes the efficient and automated assembly of fireworks inner tubes and fireworks outer tubes, significantly improves the overall automation level and assembly accuracy of the production line, reduces manual intervention and operational risks, and improves production efficiency and product consistency. At the same time, it ensures the safety and stability of the assembly process and meets the strict requirements of fireworks production for quality and safety.

[0087] The aforementioned fireworks assembly line is based on the aforementioned fireworks inner tube installation line, and its combination of technical effects and features will not be elaborated further here. The above embodiments merely illustrate several implementation methods of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
