Description

Technical Field

[0001] This utility model relates to the field of fireworks production technology, and in particular to a gunpowder filling device for combination fireworks tubes. Background Technology

[0002] Combination fireworks are fireworks products composed of multiple single tubes, producing various effects such as sound, light, color, and floating debris when ignited. Based on the type of effect, combination fireworks can be divided into single-type combination fireworks and multi-type combination fireworks. Single-type combination fireworks consist of single tubes with similar effects, such as those that emit sparks or spray flowers; while multi-type combination fireworks consist of single tubes with different effects. The design of the ignition process for combination fireworks relies on ignition delay technology. Traditionally, the delay for the second and subsequent ignitions in combination fireworks is usually achieved by a timed fuse, which greatly limits the design flexibility of the fireworks ignition process and makes it difficult to achieve rich combinations of effects. Furthermore, the low precision of the timed fuse also affects the ignition effect. To overcome these problems, modern technology uses a microcontroller to directly control the ignition time of each single tube, achieving precise ignition delay control through a preset ignition sequence list, even down to the millisecond level, thereby greatly improving the ignition effect and design freedom of combination fireworks.

[0003] The gunpowder filling process in combination fireworks tubes is a crucial step in fireworks production, typically requiring the filling of multiple tubes. Traditional gunpowder filling relies heavily on manual operation, resulting in low efficiency and poor safety. To improve production efficiency and safety, modern technology focuses on automating gunpowder filling. For example, the development of fully automated fireworks inner tube filling machines, employing sensor-based automatic weighing and mechanical automation control, enables the automatic filling and mixing of single-element materials within the tube. This technology not only improves production efficiency but also significantly reduces safety risks by minimizing human-gunpowder and human-machine contact. Furthermore, to further enhance safety, a new "fill-then-mix" process has been adopted, eliminating the pre-mixing operation of the explosive charge. Instead, a robotic arm directly performs micro-mixing of materials within the tube, avoiding the presence of exposed explosive charge and further reducing the dangers of the gunpowder filling process. The development and application of these technologies provide safer and more efficient solutions for the production of combination fireworks.

[0004] Patent document CN217330908U discloses a gunpowder filling device for combined fireworks tubes, including a conveyor belt, an mounting plate disposed above the middle of the conveyor belt, a sliding metering cylinder slidably disposed on the mounting plate, an elongated hopper disposed on the sliding metering cylinder, and the elongated hopper being fixedly disposed on the conveyor belt by a mounting frame; guide hoppers are spaced apart on one side of the mounting plate, a measuring cylinder cooperating with the guide hopper is disposed on one side of the sliding metering cylinder, and a back plate 3 is disposed on the other side; a movable partition is vertically disposed inside the measuring cylinder, a partition strip is disposed above the side of the partition, and a fixing plate 3 is disposed in the middle of the partition; a threaded rod is disposed between the back plate 3 and the left side wall of the measuring cylinder, and a threaded hole cooperating with the threaded rod is disposed on the fixing plate 3; the purpose of this utility model is to provide a gunpowder filling device for combined fireworks tubes, capable of quantitative gunpowder filling, and filling different amounts of gunpowder into the fireworks tube according to requirements.

[0005] As in the prior art of the aforementioned patent, the number of guide hoppers in the aforementioned device is fixed. When it is necessary to fill the gunpowder of a combination of fireworks with different numbers of fireworks tubes, since the number of guide hoppers is fixed, it is impossible to control the excess guide hoppers from feeding. This will cause some of the gunpowder discharged from the guide hoppers to fall outside the fireworks tubes, such as above the conveyor belt. Therefore, the guide hoppers of the lifting device can only be used for filling the gunpowder of a combination of fireworks with a corresponding number of fireworks tubes. Utility Model Content

[0023] Reference Figure 1-4A gunpowder filling device for a combination fireworks tube includes a compression filling mechanism and support frames 5 disposed on both sides of the compression filling mechanism. A discharge trough 7 is disposed between the two support frames 5. A feeding hopper 9 is disposed at the top of the discharge trough 7. An anti-blocking component is disposed between the feeding hopper 9 and the discharge trough 7. Multiple discharge ports 13 are opened at the bottom of the feeding hopper 9. A sealing block 14 is slidably installed inside the feeding hopper 9. Two sealing blocks 14 are respectively disposed on both sides of the multiple discharge ports 13. An adjustment component is disposed between the two sealing blocks 14 and the support frames 5. The combination fireworks tube to be filled with gunpowder is placed on a placement platform 6 inside the compression filling mechanism. The gunpowder to be filled is put into the hopper 9 and discharged through the discharge port 13 below the hopper 9. Then, the gunpowder is fed into each module of the filling tube assembly 4 on the compression filling mechanism, thereby realizing the filling of gunpowder. When the number of filling modules 401 of the filling tube assembly 4 on the compression filling mechanism is different, the two blocking blocks 14 are adjusted by adjusting the component to slide simultaneously towards the middle of the discharge trough 7 to block the discharge port 13, retaining the required number of discharge ports 13. When the discharge trough 7 feeds again, it will only discharge from the corresponding number of discharge ports 13, thus meeting the filling requirements of the tube compression filling mechanism with different numbers of filling modules 401.

[0024] As a preferred technical solution in this embodiment, the top ends of the two blocking blocks 14 are provided with inclined surfaces 19; the inclined surfaces 19 are provided so that when the gunpowder falls above the blocking block 14, it can slide down along the inclined surfaces 19 and be discharged smoothly from the discharge port 13, without accumulating on the top of the blocking block 14.

A placement platform 6 is located below the frame 1. Gunpowder enters the filling modules 401 on the filling tube assembly 4 through the discharge ports 2. The cylinder 3 then drives the filling tube assembly 4 to descend, thereby controlling the insertion of multiple filling modules 401 into the interior of the fireworks tube above the placement platform 6, thus achieving gunpowder filling.

[0026] As a preferred embodiment, the anti-blocking component includes an anti-blocking groove 8, which is fixedly installed between the feeding hopper 9 and the discharge chute 7. Two grinding rollers 12 are rotatably installed inside the anti-blocking groove 8.

A second motor 10 is fixedly installed at one end of the anti-blocking groove 8, and the output end of the second motor 10 is connected to one end of one of the grinding rollers 12. The rotation of the second motor 10 can drive one of the grinding rollers 12 to rotate. Under the action of the meshing rotation of the two gears 11, the two grinding rollers 12 can rotate relative to each other. On the one hand, the gunpowder can be further ground, and on the other hand, large pieces of gunpowder can be prevented from clogging during the feeding process.

[0027] As a preferred technical solution of this embodiment, the adjustment component includes a movable frame 15 fixedly installed at one end of the two sealing blocks 14, and screws 16 are rotatably installed on the side walls of the two support frames 5.
