Description

Technical Field

[0001] This invention relates to a processing apparatus for combination fireworks. Background Technology

[0002] Combination fireworks typically consist of several firework tubes arranged in a single row, called a tube row. Then, the tubes in the tube row are perforated and fitted with fuses; ignition holes are drilled into each tube using a punch, and fuses are inserted into these holes, connecting the tubes to form a ignition link. Several tube rows are then stacked and assembled into a block shape, called a "combination firework," resulting in a combination firework. The firework tubes contain propellant and effect components, ignited by the fuses. The equipment used to complete this assembly is commonly referred to in the industry as a "combination firework machine" or "firework assembly machine," and it is a relatively mature and widely used type of fireworks machinery.

[0003] Firework tubes in a firework array can be categorized into two types based on their distribution and arrangement: spaced arrays and unspaced arrays. Spaced arrays refer to adjacent firework tubes where the sidewalls are spaced apart. Unspaced arrays refer to adjacent firework tubes where the sidewalls are touching. Currently developed assembly equipment targets mainstream combination firework products on the market, and its arrays are all unspaced.

[0004] In addition, firework tube arrays can be divided into upright arrays and irregular arrays. Irregular arrays feature firework tubes arranged in various shapes, such as fan-shaped, W-shaped, V-shaped, left-leaning, right-leaning, and five-finger shapes. The axes of the firework tubes in irregular arrays have a certain angle of inclination (launch deflection angle). Unlike irregular arrays, the axes of the firework tubes in upright arrays are parallel and side-by-side.

[0005] In practice, we have found that to achieve controlled firing rhythm and a set firing delay in combination fireworks, slow-speed fuses, such as those with a burning rate of 100 seconds per meter, are needed between adjacent firework tubes in a firework array. However, the slower the burning rate, the less propellant is contained within the fuse, making it more prone to misfiring. Compared to unspaced firework arrays, spaced firework arrays, by maintaining distance between adjacent firework tubes, allow for a longer burning rate of the fuse. With this increased length, fuses with a relatively faster burning rate, such as those with a burning rate of 60 seconds per meter, can be used to achieve the same firing delay, thus reducing the probability of misfiring. Simultaneously, spaced firework arrays increase the cross-sectional area of ​​the combination fireworks, improving overall stability and preventing tube tipping during firing. Spaced firework arrays also maintain a safe distance between firework tubes, preventing secondary explosions.

[0006] Therefore, the combination fireworks formed by assembling spaced tubes have positive significance in improving quality and safety. However, the lack of adjacent side support between the firework tubes in spaced tubes leads to deteriorated structural stability, making reliable assembly, transportation, and positioning difficult. The processing difficulty or requirements are significantly different from those of unspaced tubes. In the early research and development, we developed a device, Chinese invention patent document titled "A Processing Device for Spaced Irregularly Shaped Tubes of Combined Fireworks", publication number: CN120313421A, publication date: 2025-07-15. Although this device also involves the processing of spaced tubes, it obtains irregularly shaped tubes through the positioning and swinging of guide tube components, and is only suitable for the assembly and processing of irregularly shaped tubes, not for upright tubes. In the prior art, spaced upright tubes are all made manually, usually relying on adhesive to cover a layer of fireproof paper on the tubes to maintain the structural strength of the tubes for assembly.

[0007] Therefore, the existing technology lacks a device capable of assembling and processing spaced vertical cylindrical tubes. Summary of the Invention

[0008] To address the aforementioned drawbacks, the technical problem this invention aims to solve is to provide a device capable of reliably assembling, conveying, and positioning spaced, upright cylindrical fireworks. The technical solution adopted by this invention is an assembly and conveying device for spaced cylindrical fireworks, comprising a progressively lifting receiving platform connected to a workbench. The workbench is divided into several material distribution slots by several parallel limiting strips. A pusher pushes the fireworks tubes in the distribution slots onto the receiving platform. The device is characterized by a receiving assembly above the receiving platform, comprising several slots separated by several parallel separating members, the separating members corresponding to the limiting strips; a movable bottom support assembly supporting the fireworks tubes within the slots; a pressing member above the slots, capable of moving downwards to apply downward pressure to the fireworks tubes within the slots; when the pressing member presses the fireworks tubes downwards, the movable bottom support assembly opens, allowing the fireworks tubes to fall from the bottom of the slots onto the receiving platform along with the pressing member.

[0009] The beneficial effect of this invention is that when the pusher pushes the firework tubes in the distribution trough towards the receiving platform, it does not push them directly onto the receiving platform, but rather pushes them into the trough of the receiving assembly for a transition. The firework tubes fed into the trough are supported on the lower side by a movable bottom support assembly and constrained on the left and right sides by separating components, forming a firework tube positioning system during the transition period; then, under the constraint of the separating components, the pressing component presses the firework tubes in the trough onto the receiving platform. The entire process ensures sufficient constraint on the firework tubes and smooth operation. This reliably completes the assembly, conveying, and positioning of spaced, upright tube arrays, and reliably completes the assembly process.

[0010] In one embodiment, the movable bottom support assembly can switch between open and closed states by at least one of reciprocating swing, elastic deformation, or elastic retraction; when the pressing member presses the firework tube inside the tank downward, the movable bottom support assembly enters the open state under the indirect pressure of the pressing member, so that the firework tube inside the tank can fall from the bottom of the tank with the pressing member, and after the firework tube falls, the movable bottom support assembly resets to the closed state.

[0011] In one embodiment, the movable bottom support assembly includes at least two symmetrically arranged bottom support units, each of which can swing around its connection point with the tank body to open and close the bottom support assembly.

[0012] In one embodiment, the movable support assembly is made of a material with elastic deformation capability, which can deform to form a channel for the fireworks tube to pass through when subjected to indirect pressure from the pressing member.

[0013] In one embodiment, the movable bottom support assembly employs an elastic support member connected to the trough, which can retract to form a channel for the fireworks tube to pass through when subjected to indirect pressure from the pressing member.

[0014] In one embodiment, the movable bottom support assembly includes an elastic support member and a bottom support plate. The bottom support plate is connected to the trough through the elastic support member. When subjected to indirect pressure from the pressing member, the elastic support member can retract, causing the bottom support plate to move downward to open the channel through which the fireworks tube passes.

[0015] In one embodiment, the connection between the worktable and the receiving platform is provided with an angle correction mechanism to prevent the front end of the firework tube from falling during its forward ejection from the distributing trough. This mechanism includes an angle correction component located at the front end of the distributing trough, the component having a force-applying part that acts on the front end of the firework tube. The force-applying part is positioned higher than the bottom of the distributing trough. When the firework tube is ejected forward from the distributing trough, the force-applying part applies an upward force to the front end of the firework tube, causing it to be ejected from the distributing trough in a forward-upward tilted posture. This ensures that the firework tube can smoothly enter the receiving assembly's trough from the distributing trough.

[0016] In one embodiment, the angle correction component is a ramp structure, the force application part is the inclined surface of the ramp structure, and the inclined surface forms a preset angle with the bottom of the material distribution trough.

[0017] In one embodiment, the angle correction component is a rotating roller structure, the force application part is the top area of ​​the roller surface of the rotating roller structure, and the highest point of the rotating roller structure is slightly higher than the bottom of the material distribution trough.

[0018] In one embodiment, rollers are provided on both sides of the distribution trough, and the rollers act on the side walls of the firework tubes inside the distribution trough. During the process of the pusher pushing the firework tubes from the distribution trough onto the receiving platform, the accurate direction of movement and smooth forward motion of the firework tubes are ensured.

[0019] In one embodiment, the spacer feeding mechanism is provided with a glue application assembly for the anti-fire spacer. The assembly includes a glue application roller disposed on the spacer ejection path to apply glue to the top and / or bottom of the spacer. The glue application roller has a notch in the middle and a glue supply component.

[0044] Example 1: See Appendix Figures 1-5 This describes a specific structure of the present invention. In this working scenario, the assembly and conveying device for the spaced-out tube array is installed on the assembly machine. Firework tubes 900 stored in the hopper 1 of the assembly machine are distributed to various distribution slots 201 on the work panel 2. The firework tubes 900 in each distribution slot 201 are connected end-to-end and pushed to the receiving platform 3 by the pusher 202. During the pushing process, the ignition fuse 901 is installed by the punching and inserting device 203. In this example, six firework tubes 900 connected by the ignition fuse 901 constitute a spaced-out tube array. Adhesive is applied to the firework tubes 900 by the gluing device 204. Pushed by the pusher 202, the spaced-out tube array is sequentially fed into the receiving platform 3 via the assembly and conveying device. In this example, the six spaced-out tube arrays are stacked on the receiving platform 3 to form a block 902, which is then pushed out by the pusher 4.

[0045] The example also includes a spacer bar feeding mechanism 5. For safety or structural reasons, spacer bars 501 need to be placed between the rows of tubes in the block-shaped integral 902 to increase the distance between the two rows. In the assembly machine, after the first row of tubes is inserted, it enters the lifting receiving platform 3 of the corresponding station, and then the first set of spacer bars is fed in to press on the first row of tubes; the receiving platform 3 descends, the second row of tubes enters and presses on the first set of spacer bars, and then the second set of spacer bars is fed in to press on the second row of tubes. This process is repeated until the processing of a block-shaped integral 902 is completed. The specific structural principle of the spacer bar feeding mechanism 5 can be found in Chinese Patent Document CN2017207680838: Invention Title: A Spacer Bar Installation Mechanism for Combined Fireworks; Authorization Announcement Number: CN207147327U; Authorization Announcement Date: 2018-03-27.

[0046] The above process, except for the assembly and conveying device with spaced tubes, uses mature technologies from fireworks assembly machines, which will not be elaborated further.

[0047] The assembly and conveying device for the spaced cylindrical array includes a progressively lifting receiving platform 3 connected to the workbench 2. In the example, the platform motor 301 drives the receiving platform 3 to rise and fall progressively along the platform guide rail via a screw and nut assembly.

[0048] The worktable 2 is divided into several material distribution slots 201 by several parallel limiting strips 205. A pusher 202 pushes the firework tubes 900 in the material distribution slots 201 onto the receiving platform 3. In this example, rollers 2011 are provided on both sides of the material distribution slots 201, and the rollers 2011 act on the side walls of the firework tubes 900 within the material distribution slots 201. During the process of the pusher 202 pushing the firework tubes in the material distribution slots 201 onto the receiving platform 3, the accurate direction of movement and smooth forward motion of the firework tubes are ensured.

[0049] A receiving assembly is provided above the receiving platform 3. The receiving assembly includes several grooves 6 separated by several parallel separating members 601. The separating members 601 are set corresponding to the limiting strip 205. In the example, the separating members 601 are suspended above the receiving platform 3 by the frame hoisting rod 604.

[0050] A pressing member 7 is provided above the trough 6. The pressing member 7 can move downward to apply downward pressure to the firework tubes 900 inside the trough 6. In the example, the pressing member 7 consists of two horizontal bars that are connected to the pressing cylinder 701 and move up and down. When the horizontal bars move downward, they correspond to the two ends of the firework tubes in the pressing tube array.

[0051] The lower part of the trough 6 is provided with a movable bottom support assembly to support the firework tube 900 inside the trough 6. When the pressing member 7 presses the firework tube inside the trough downward, the movable bottom support assembly can open, allowing the firework tube 900 inside the trough 6 to fall from the bottom of the trough 6 onto the receiving platform 3 along with the pressing member 7.

[0052] In the example, the movable bottom support assembly includes at least two symmetrically arranged bottom support units—spring plates 602. When the pressing member 7 presses down on the firework tube 900 in the trough 6, the spring plates 602 are indirectly pressured by the pressing member 7. Each spring plate 602 can swing downward around its connection point 603 with the bottom of the separating member 601, entering the open state, so that the firework tube 900 in the trough 6 can fall from the bottom of the trough 6 with the pressing member 7. After the firework tube 900 has fallen, the spring plate 602 elastically returns to the closed state. This realizes the opening and closing of the bottom support assembly.

[0053] In the example, the spacer bar feeding mechanism 5 feeds a set of spacer bars 501 onto the first cylindrical section of the receiving platform 3. The receiving platform 3 descends one station and repeats the above process to process the second cylindrical section. The second cylindrical section is stacked and glued onto the spacer bars 501 of the first cylindrical section. This process continues until the receiving platform 3 reaches the lower limit station, forming a block-shaped integral 902 composed of six cylindrical sections and five sets of spacer bars 501. The pusher 4 pushes the block away from the receiving platform 3, and then the receiving platform 3 rises and resets to begin processing the next block-shaped integral 902.

[0054] Each block 902, pushed off the receiving platform 3 by the pusher 4, is connected end to end and pushed forward synchronously: first, it enters the tape binding device 8 through the conveyor channel 402, and is bound and fixed around the outer periphery of the block 902 with tape, and then moves forward to the discharge slide plate 401 for delivery.

[0055] Using the above technical solution, when the pusher 202 pushes the firework tubes 900 in the distribution trough 201 onto the receiving platform 3, it does not push them directly onto the receiving platform 3, but rather pushes them into the trough 6 of the receiving assembly for a transition. The firework tubes fed into the trough 6 are supported on the lower side by a movable bottom support assembly and constrained on the left and right sides by separation members 601, forming a firework tube positioning system during the transition period; then, under the constraint of the separation members 601, the pressing member 7 presses the firework tubes in the trough 6 down onto the receiving platform 3. The firework tubes 900 are sufficiently constrained and work smoothly throughout the entire process. This reliably completes the assembly, conveying, and positioning of the spaced, upright tube array. The two symmetrically arranged bottom support units in the movable bottom support assembly effectively prevent the firework tubes 900 from rolling, especially during the process of the firework tubes 900 falling from the trough 6, preventing the ignition fuse 901 from shifting and falling off the tube. In the example, the rod 605 below the separator 601 acts as a clamp to restrain the firework tube, so that the firework tube 900 can still be restrained as it falls from the bottom of the trough 6 to the receiving platform 3.

[0056] In the example, the connection between the workbench 2 and the receiving platform 3 is equipped with an angle correction mechanism to prevent the front end of the firework tube 900 from falling during its forward ejection from the material distribution trough 201. This mechanism includes an angle correction component 2012 located at the front end of the material distribution trough 201. The angle correction component 2012 has a force-applying part that interacts with the front end of the firework tube 900, and the force-applying part is positioned higher than the bottom of the material distribution trough 201. When the firework tube 900 is ejected forward from the material distribution trough 201, the force-applying part applies an upward force to the front end of the firework tube 900, causing the front end of the firework tube 900 to be ejected from the material distribution trough 201 in a forward and upward tilted posture. This ensures that the firework tube 900 can smoothly enter the receiving assembly's trough 6 from the material distribution trough 201. Simultaneously, the front end of the firework tube 900 will not push the previously placed spacer bars 501, preventing the spacer bars 501 from tilting or changing position.

[0057] In this example, the angle corrector 2012 is a rotating roller structure, and the force-applying part is the top area of ​​the roller surface of the rotating roller structure. The highest point of the rotating roller structure is slightly higher than the bottom of the material distribution trough 201. The height difference between the highest point of the rotating roller structure and the bottom of the material distribution trough 201 ranges from 2 to 20 mm, mainly depending on the length of the fireworks tube. In other embodiments, the angle corrector 2012 can also be a ramp structure, and the force-applying part is the inclined surface of the ramp structure. The inclined surface forms a preset angle with the bottom of the material distribution trough 201. The preset angle ranges from 5 to 30 degrees, mainly depending on the length of the fireworks tube.

[0058] Example 2: See Appendix Figure 6This reflects another specific structure of the present invention. The difference from Embodiment 1 is that the movable support assembly is made of a rubber sheet 602-1 with elastic deformation capability. When subjected to indirect pressure from the pressing member 7, it can deform to form a channel for the firework tube 900 to pass through. After the firework tube 900 falls through, the rubber sheet 602-1 elastically deforms back to the closed state, thus realizing the opening and closing of the support assembly.

[0059] Example 3: See Appendix Figure 7 This reflects another specific structure of the present invention. The difference from Embodiment 1 is that the movable support assembly is made of a brush body 602-2 with elastic deformation capability. When subjected to indirect pressure from the pressing member 7, it can deform to form a channel for the firework tube 900 to pass through. After the firework tube 900 falls through, the brush body 602-2 elastically deforms back to the closed state, thus realizing the opening and closing of the support assembly.

[0060] Example 4: See Appendix Figure 8 This reflects another specific structure of the present invention. The difference from Embodiment 1 is that the movable support assembly uses an elastic steel ball assembly 602-3 connected to the separator 601 of the trough via a spring. When subjected to indirect pressure from the pressing member 7, the spring in the elastic steel ball assembly 602-3 is compressed, and the steel balls retract, thus forming a channel for the fireworks tube to pass through. After the fireworks tube 900 falls through, the steel balls elastically return to the closed state, thereby realizing the opening and closing of the support assembly.

[0061] Example 5: See Appendix Figure 9 This reflects another specific structure of the present invention. The difference from Embodiment 1 is that the movable bottom support assembly uses a torsion spring hinge 602-4. The torsion spring hinge 602-4 includes an elastic support member—a torsion spring—and a bottom support plate—a hinge. The hinge is connected to the separator 601 of the groove body via the torsion spring. When subjected to indirect pressure from the pressing member 7, the torsion spring twists and retracts, causing the hinge to move downwards to open the passage for the firework tube. After the firework tube 900 falls through, the hinge returns to the closed state. This achieves the opening and closing of the bottom support assembly.

[0062] Example 6: See Appendix Figures 10-12 This describes a specific structure of the spacer bar feeding mechanism 5 of the present invention. Each group of spacers 501 includes a first spacer bar 501-A and a second spacer bar 501-B. Driven by the cylinder assembly 504, the pusher rod assembly 503 on the sliding frame reciprocates along the guide rail assembly, pushing the first spacer bar 501-A and the second spacer bar 501-B stacked in the storage rack assembly one by one (group) onto the cylinder of the receiving platform 3.

[0063] In the example, the first spacer bar 501-A is used to enclose the installation position of the ignition lead 901 in the tube array, enabling this component to serve two functions: providing a safety gap and preventing crossfire, as well as securing the lead. Simultaneously, using the assembly and conveying device of this invention, the reliance on fireproof paper to maintain the structural strength of the tube array is eliminated during manufacturing. Therefore, fireproof paper is no longer needed between tube arrays, reducing the number of assembly components during the production of combined fireworks. While effectively preventing crossfire, this significantly improves production efficiency and reduces production costs. The first spacer bar 501-A can be referred to as the anti-crossfire spacer bar.

[0064] However, the anti-sparking spacer strip must be glued to the cylinder on both sides for effective fixation. The glue used for this process can wet the ignition lead 901, causing it to seep into the lead and potentially leading to flameout even after the lead has cured and dried. Therefore, the contact surface between the first spacer strip 501-A and the ignition lead 901 is divided into a glued area and a non-glued area along the length of the spacer strip. The non-glued area corresponds to the ignition lead installation area. The first spacer strip 501-A is glued to the cylinder through the glued area, enclosing the ignition lead installation area inside the spacer strip. Since there is no glue between the non-glued area and the ignition lead installation area, glue entry into the lead is prevented, thus avoiding flameout.

[0065] To achieve the above technical solution, in this example, the spacer feeding mechanism is equipped with a glue application component for the anti-crossfire spacer. This component includes a glue application roller 505 disposed on the spacer ejection path to apply glue to the top and / or bottom of the spacer. The glue application roller 505 has a notch 506 in the middle. The glue application roller 505 is equipped with a glue supply component. The glue supply component of the lower glue application roller 505 is such as a glue box 507 that is immersed in the lower glue application roller 505. The glue supply component of the upper glue application roller 505 is such as a glue tube (not shown in the figure) with the glue outlet end mounted on a bracket 508. The glue tube drips glue onto the upper glue application roller 505. Due to the notch 506, this glue application component can easily apply glue to the top and bottom of the first spacer 501-A and divide the spacer into a glued area and a non-glued area along the length of the spacer.

[0066] Example 7: See Appendix Figures 13-16This describes a specific structure of the hopper 1 of the present invention. It achieves intermittent distribution of firework tubes, allowing a large number of firework tubes 900 piled in the hopper 1 to be arranged in an orderly manner with spacing, facilitating the processing of spaced tube arrays. Several distribution intervals 101 are supported below the hopper 1. The distribution intervals 101 on the working panel 2 are correspondingly connected to each distribution groove 201. Firework tubes 900 falling into each distribution interval 101 are correspondingly delivered to each distribution groove 201 by the push rods 2021 of the pusher 202. The hopper 1 is equipped with a pusher assembly 102 to smoothly guide the firework tubes 900 downwards. The distribution intervals 101 are equipped with guide components to guide the firework tubes in the hopper 1 into the distribution intervals 101. In this example, the guide components include guide seats 103 at both ends, with the tops of the two guide seats connected by a guide line 104.
