Description

Technical Field

[0001] The utility model relates to a charge loading production line, in particular to an inner cylinder charge loading production line for combined fireworks. Background Art

[0002] Combined fireworks are fireworks products composed of multiple single cylinders, which are ground fireworks that can produce effects such as sound, light, and color during ignition. The inner cylinder is the core component of combined fireworks, and various materials such as flash beads and primer are filled inside. The types, proportions, and filling quality of these materials directly affect the ignition effect and safety of fireworks.

[0003] In the production of combined fireworks, the production of the inner cylinder is a key process in the manufacturing process of combined fireworks, and its quality and consistency directly determine the performance of the final product. The traditional production of the inner cylinder of combined fireworks relies on manual operation. The specific steps are as follows: The first step is to mix raw materials such as potassium perchlorate, silver powder, sulfur, and alloy into primer according to a certain ratio; the second step is to manually load flash beads into the inner cylinder of combined fireworks; the third step is to manually load the mixed primer into the inner cylinder of combined fireworks; the fourth step is to use a sealing agent to tightly seal the flash beads and primer in the inner cylinder of combined fireworks to complete the charge loading process. Since the flash beads and primer used in the production of the inner cylinder of combined fireworks are explosive, there are relatively high safety risks in the production process. Manual operation is not only inefficient but also difficult to ensure the consistency of drug mixing and filling, easily leading to unstable product quality. In addition, manual operation also increases the safety risks of operators and is not conducive to safe production.

[0004] Therefore, this patent provides a production line for the production of the inner cylinder of combined fireworks, which adopts mechanization and automation technologies to achieve efficient, safe, and stable production of the inner cylinder. Summary of the Utility Model

Detailed implementation manners

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Embodiment 1: Please refer to Figures 1-6, the production line for the internal charge of combined fireworks, including a base 1, an explosion-proof workshop 2, an explosion-proof door 3, a conveying table 4, a fourth sensor 36 and an explosion-proof glass plate 37. The conveying table 4 is fixedly installed inside the explosion-proof workshop 2 through the base 1, and the explosion-proof door 3 is arranged outside the explosion-proof workshop 2. The fourth sensor 36 installed inside the explosion-proof workshop 2 automatically controls the opening and closing of the explosion-proof door 3 to ensure that the explosion-proof workshop 2 is quickly closed in case of an emergency to prevent the spread of danger. In addition, the explosion-proof workshop 2 is also embedded with an explosion-proof glass plate 37, which is mainly used to facilitate personnel to observe the production situation inside the workshop and has explosion-proof function at the same time. According to the production process, a cake placing machine 5, two induction explosion-proof devices, a flash powder lifting, distribution and filling integrated machine, an unpacking powder mixing machine 13, an unpacking powder filling machine 14, a sawdust conveying and filling integrated machine 20, a sealing powder conveying and filling integrated machine 21, a scraping mechanism and a sealing machine 22 are arranged in sequence on the conveying table 4 inside the explosion-proof workshop 2; the two induction explosion-proof devices are respectively located at the inlet and outlet positions of the explosion-proof workshop 2. Each induction explosion-proof device includes a first sensor 6, a gas concentration detector 7, an explosion-proof shell 8, a first support block 9, a cylinder 10, an explosion-proof plate 11 and a dust-proof curtain 38. Among them, the gas concentration detector 7 is arranged outside the explosion-proof shell 8 to monitor the concentration of combustible gas and toxic gas in the environment. The cylinder 10 is arranged on the top of the explosion-proof shell 8 through the first support block 9, and an explosion-proof plate 11 is assembled on its movable rod. The gas concentration detector 7 controls the switch of the cylinder 10 through the first sensor 6. When the gas concentration detector 7 detects abnormal environmental gas concentration, it will automatically control the action of the cylinder 10 through the first sensor 6 to drive the explosion-proof plate 11 to move down, thereby closing the explosion-proof shell 8 to achieve the explosion-proof function. In addition, dust-proof curtains 38 are arranged at the inlet and outlet of the explosion-proof shell 8, which are mainly used to prevent dust and harmful gases generated during the production process from escaping into the external environment; the scraping mechanism is arranged behind the sealing powder conveying and filling integrated machine 21, mainly including two second support blocks 15, a first threaded rod 16, a handwheel 17, a scraper 18 and a guide rod 19. The first threaded rod 16 and the guide rod 19 are respectively arranged on the two second support blocks 15. The scraper 18 is slidably arranged on the guide rod 19 and is driven to move by the first threaded rod 16. In addition, a handwheel 17 is installed at the top of the first threaded rod 16, and the height of the scraper 18 can be adjusted by rotating the handwheel 17 to drive the first threaded rod 16.

[0027] Production process of the internal charge of combined fireworks:

[0028] First, the inner cylinder cakes are placed from the cake placer 5 onto the conveyor table 4. As the conveyor table 4 operates, the inner cylinder cakes are successively conveyed backward. During this process, the bright bead lifting, dispensing, and filling integrated machine 12 is responsible for lifting and dispensing the bright beads to the hopper. When the inner cylinder moves below this device, the filling of the bright beads is automatically completed. Then, the unpacking charge mixer 13 mixes raw materials such as potassium perchlorate, silver powder, sulfur, and alloy into the unpacking charge according to a specific ratio. The mixed unpacking charge is fed into the hopper of the unpacking charge filling machine, and then the unpacking charge filling machine accurately loads it into each inner cylinder. The inner cylinders that have completed the unpacking charge filling continue to move along the conveyor table 4 and successively reach below the wood chip conveying and filling integrated machine 20 and the sealing powder conveying and filling integrated machine 21 to achieve the filling of the sealing material. Subsequently, a scraper 18 is used to evenly and smoothly lay the sealing material at the opening of the inner cylinder to prepare for the next sealing step. Finally, the inner cylinder completes the sealing operation through the sealing machine 22, and thus the production process of the entire combined fireworks inner cylinder ends. During the entire production process, through the gas concentration detector 7 in the induction explosion-proof device, the concentrations of combustible gases and toxic gases in the workshop are monitored in real time. If the detected gas concentration exceeds the preset safety threshold, the gas concentration detector 7 will immediately trigger an alarm and send a command to the cylinder 10 through the first sensor 6 to drive the explosion-proof plate 11 to quickly move downward to close the feeding port and discharging port of the explosion-proof workshop 2 and prevent the spread of the explosion.

[0029] Embodiment 2: On the basis of Embodiment 1, please refer to Figure 7 , and there is also a mixing mechanism on the conveyor table 4. The mixing mechanism starts to operate after the unpacking charge filling and the sealing powder filling respectively, and includes a support frame 23, a fixing block 24, a double-shaft motor 25, two second threaded rods 26, two push plates 27, and a second sensor 28. The two push plates 27 are slidably arranged on the support frame 23. The double-shaft motor 25 is arranged in the middle of the support frame 23 through the fixing block 24. The double-shaft motor 25 is controlled by the second sensor 28 to operate. The output shafts at both ends of the double-shaft motor 25 are respectively connected with a second threaded rod 26. The second threaded rods 26 are respectively threadedly connected to the adjacent push plates 27 to drive the push plates 27 to move. When the double-shaft motor 25 is started, it can drive the two push plates 27 to slide along the support frame 23, thereby pushing the inner cylinder cakes to move, so as to realize the mixing of the materials.

[0030] After the inner cylinder has undergone the unpacking charge filling and the sealing powder filling, it will move to the mixing position. At this time, the second sensor 28 senses that the inner cylinder is in place and starts the double-shaft motor 25. The double-shaft motor 25 drives the two push plates 27 to continuously move, pushing the inner cylinder back and forth, causing the inner cylinder to shake, so that the bright beads and the unpacking charge are evenly mixed. After the mixing is completed, the two push plates 27 return to their original positions and push the inner cylinder back to the central position for the next operation.

[0031] Please refer to Figure 8 andFigure 9 Moreover, a fire-fighting mechanism is also equipped on the explosion-proof workshop 2. The fire-fighting mechanism includes two water storage tanks 29, a water inlet pipe 30, a water pump 31, a water delivery pipe 32, a water distribution pipe 33, a sprinkler 34 and a third sensor 35. The two water storage tanks 29 are both arranged on the top of the explosion-proof workshop 2 and are connected to an external water source through the water inlet pipe 30. The water in the water storage tank 29 is output through the internal water pump 31. In addition, the start and stop of the water pump 31 are controlled by the third sensor 35. The water delivery pipe 32 is arranged inside the explosion-proof workshop 2, and four water distribution pipes 33 are evenly distributed on the water delivery pipe 32. Three sprinklers 34 are installed on each water distribution pipe 33.

[0032] After the explosion-proof device is activated, the third sensor 35 will immediately send a signal to start the water pump 31. After the water pump 31 is started, the water in the water storage tank 29 is conveyed into the explosion-proof workshop 2 through the water delivery pipe 32 and then sprayed out by the sprinklers 34 to cover all areas inside the explosion-proof workshop 2, forming a dense water curtain to quickly reduce the fire and suppress the spread of the fire. When the fire is extinguished or the abnormal situation is eliminated, the third sensor 35 will stop sending signals, the water pump 31 will automatically close, and the sprinklers 34 will stop spraying water.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes may be made therein without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
