Description

Technical Field

[0001] This application relates to the field of fireworks production technology, and in particular to a filling and pressing production line for fireworks that emit sparks. Background Technology

[0002] Fireworks that emit sparks or colored sparks are products that systematically launch colored sparks, flowers, or sound effects from the same tube. Specific types of fireworks that emit sparks include chain-fire fireworks, which are typically composed of a dozen or more chain-fire fireworks that create an effect similar to Gatling gun fire, characterized by a large propellant charge, high rate of fire, and great power.

[0003] During the production of sparkler-type fireworks, multiple layers of propellant are loaded into the firework tube. Each layer includes three materials: gold powder, launching gunpowder, and bright beads. The gas generated by the combustion of the launching gunpowder propels the bright beads into the air, creating a sound and light effect. Each layer of propellant can form one launch. Currently, most production equipment for sparkler-type fireworks on the market is a pressing device. This device can only assist manual labor in compressing the propellant in the firework tube. For example, Chinese Patent CN202023010439.2 discloses a pressing device for sparkler-type fireworks, which uses a pressing rod to compress the propellant in the inner tube. This type of pressing equipment has a low degree of automation, low efficiency, and significant safety hazards. Utility Model Content

[0035] The following is a specific embodiment of the present application and further describes the technical solutions of the present application in conjunction with the drawings, but the present application is not limited to these embodiments. In the following description, specific details such as specific configurations and components are provided only to help 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 can be made to the embodiments described herein without departing from the scope of protection of the present application. In addition, in order to be clear and concise, the description of known functions and structures is omitted.

[0036] It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0037] The present application provides a spitting bead firework filling and compacting production line, which can be used for automatic production of spitting bead fireworks. Referring to Figure 1 , the spitting bead firework filling and compacting production line comprises a circumferential conveying mechanism 10; the circumferential conveying mechanism 10 forms a circumferential circle; the circumferential conveying mechanism 10 is used for conveying the firework tube W along the circumferential direction; the circumferential conveying mechanism 10 is sequentially provided with a gold powder filling device 41, a first compacting device 42, a military nitrate filling device 43, a bright bead filling device 44, and a second compacting device 45; wherein the gold powder filling device 41 is used for gold powder filling of the firework tube on the circumferential conveying mechanism 10, the first compacting device 42 is used for compacting the filling material in the firework tube after gold powder filling, the military nitrate filling device 43 is used for military nitrate filling of the firework tube on the circumferential conveying mechanism 10, the bright bead filling device 44 is used for bright bead filling of the firework tube on the circumferential conveying mechanism 10, and the second compacting device 45 is used for compacting the filling material in the firework tube after bright bead filling. Here, the firework tube W is composed of multiple spitting bead firework single tubes.

[0038] When the production line for filling and compacting the spitting bead type firework is working, the circumferential conveying mechanism 10 circulates the firework cylinder W along the circumference. After each circulation, the gold powder filling device 41 fills the firework cylinder on the circumferential conveying mechanism 10 with gold powder, the first compacting device 42 compacts the filling material in the firework cylinder, the military nitrate filling device 43 fills the firework cylinder on the circumferential conveying mechanism 10 with military nitrate, the bright bead filling device 44 fills the firework cylinder on the circumferential conveying mechanism 10 with bright beads, and the second compacting device 45 compacts the filling material in the firework cylinder again after the bright beads are filled. In this way, the filling and compacting of one layer of the filling material are completed. With the circulation of the firework cylinder on the circumferential conveying mechanism 10 for multiple times, the gold powder filling device 41, the first compacting device 42, the military nitrate filling device 43, the bright bead filling device 44, and the second compacting device 45 can realize the automatic multi-layer filling of the firework cylinder, which is high in efficiency and safe for the operators as they do not need to approach the filling and compacting equipment.

[0039] The firework cylinder W is composed of multiple spitting bead type firework single cylinders. In an embodiment, multiple moving frames 11 are arranged on the circumferential conveying mechanism 10 at intervals to place the firework cylinders.

[0040] The circumferential conveying mechanism 10 forms a circumferential circle to circulate the firework cylinder W along the circumference, which can be a belt mechanism or a chain mechanism. When the circumferential conveying mechanism 10 is running, the firework cylinder W on it moves along the circumference.

[0041] Reference Figure 2 In an embodiment of the present application, the production line for filling and compacting the spitting bead type firework further comprises a feeding assembly 20 and a discharging assembly 30. The feeding assembly 20 is used to convey the firework cylinder to be filled to the circumferential conveying mechanism 10, and the discharging assembly 30 is used to output the firework cylinder filled on the circumferential conveying mechanism 10. When the production line for filling and compacting the spitting bead type firework is working, the feeding assembly 20 sends the firework cylinder W to the circumferential conveying mechanism 10, and when the firework cylinder W on the circumferential conveying mechanism 10 is filled, the discharging assembly 30 outputs it. Here, the feeding assembly 20 and the discharging assembly 30 can be used to realize automatic feeding and discharging.

[0042] Reference Figure 1 and Figure 2 In an embodiment of the present application, a sealing material filling device is further arranged on the circumferential conveying mechanism 10. The sealing material filling device is used to fill the firework cylinder on the circumferential conveying mechanism 10 with sealing material. Specifically, after the firework cylinder is filled with multiple layers of the filling material (gold powder, military nitrate, and bright beads) on the circumferential conveying mechanism 10, the sealing material filling device fills the firework cylinder with sealing material again and compacts it.

[0043] Further, the sealing material filling device comprises a first sealing material filling device 461 and a second sealing material filling device 462, and the first sealing material filling device 461 and the second sealing material filling device 462 are respectively used for filling two different sealing materials into the firework cylinder. In some cases, the first sealing material filling device 461 and the second sealing material filling device 462 are arranged on the annular conveying mechanism 10 to fill two sealing materials.

[0044] With reference to Figure 3 The gold powder filling device 41 is provided with a first feeding container 47, the first feeding container 47 provides gold powder material to the gold powder filling device 41 through a first conveying assembly; the military gunpowder filling device 43 is provided with a second feeding container 48, the second feeding container 48 provides military gunpowder to the military gunpowder filling device 43 through a second conveying assembly; the bright bead filling device 44 is provided with a third feeding container 49, the third feeding container 49 provides bright beads to the bright bead filling device 44 through a third conveying assembly; and the sealing material filling device is provided with a fourth feeding container, the fourth feeding container provides sealing material to the sealing material filling device through a fourth conveying assembly.

[0045] When the gold powder filling device 41 lacks gold powder during the working of the firework filling and building pressure production line, the operator supplements the gold powder material to the first feeding container 47, and the gold powder in the first feeding container 47 can be conveyed to the gold powder filling device 41 through the first conveying assembly. When the military gunpowder filling device 43 lacks military gunpowder, the operator supplements the military gunpowder to the second feeding container 48, and the military gunpowder in the second feeding container 48 can be conveyed to the military gunpowder filling device 43 through the second conveying assembly. When the bright bead filling device 44 lacks bright bead material, the operator supplements the bright bead to the third feeding container 49, and the bright bead in the third feeding container 49 can be conveyed to the bright bead filling device 44 through the third conveying assembly. When the sealing material filling device lacks material, the operator can supplement the material to the fourth feeding container, and the fourth feeding container can convey the material to the sealing material filling device through the fourth conveying assembly.

[0046] With reference to Figure 3 and Figure 4, the Tuzhui type firework filling and building pressure production line further comprises a first room 51, a second room 52 and a third room 53; the first room 51 is used for arranging the annular conveying mechanism 10, the gold powder filling device 41, the first building pressure device 42, the military gunpowder filling device 43, the bright bead filling device 44 and the second building pressure device 45; the second room 52 is used for arranging the second feeding container 48 and the third feeding container 49; the third room 53 is used for arranging the first feeding container 47 and the fourth feeding container; wherein the first room 51 and the second room 52 are separated by a first partition wall 54, and the first room 51 and the third room 53 are separated by a second partition wall 55; the second conveying assembly and the third conveying assembly pass through the first partition wall 54; the first conveying assembly and the fourth conveying assembly pass through the second partition wall 55. Therefore, when the gold powder filling device 41 lacks gold powder, the gold powder in the first feeding container 47 in the third room 53 can be supplemented to the gold powder filling device 41 in the first room 51 through the first conveying assembly; when the military gunpowder filling device 43 lacks military gunpowder, the military gunpowder in the second feeding container 48 in the second room 52 can be supplemented to the military gunpowder filling device 43 in the first room 51 through the second conveying assembly; when the bright bead filling device 44 lacks bright bead material, the bright bead in the third feeding container 49 in the second room 52 can be supplemented to the bright bead filling device 44 in the first room 51 through the third conveying assembly. When the sealing material filling device lacks material, the filling material in the fourth feeding container in the third room can be supplemented to the sealing material filling device in the first room through the fourth conveying assembly. Further, the military gunpowder filling device 43 and the bright bead filling device 44 are arranged on the side of the annular conveying mechanism 10 close to the first partition wall 54.

[0047] Specifically, the first room 51 is used for arranging the annular conveying mechanism 10, the gold powder filling device 41, the first building pressure device 42, the military gunpowder filling device 43, the bright bead filling device 44 and the second building pressure device 45, so that the first room 51 is used for filling and compacting the fireworks with the medicine, and the first feeding container 47, the second feeding container 48, the third feeding container 49 and the fourth feeding container are arranged in the second room 52 and the third room 53 on both sides of the first room 51. Thus, during production, the operator does not need to operate in the first room 51, but only needs to supplement the material in the second room 52 and the third room 53, so that the operator is in the room outside the filling equipment and the compacting equipment, and the safety hidden danger is smaller.

[0048] Reference Figure 3In an embodiment of the present application, the production line for filling and compacting the spout-shaped fireworks further comprises a feeding assembly 20 and a discharging assembly 30. The feeding assembly 20 is configured to feed the fireworks cylinder to be filled to the ring-shaped conveying mechanism 10. The discharging assembly 30 is configured to output the filled fireworks cylinder from the ring-shaped conveying mechanism 10. The feeding assembly 20 passes through the second isolation wall 55 from the third room 53 to the first room 51. The discharging assembly 30 passes through the second isolation wall 55 from the first room 51 to the third room 53. During production, the operator can place the fireworks cylinder to be filled on the feeding assembly 20 in the third room 53, and then the feeding assembly 20 conveys the fireworks cylinder to the ring-shaped conveying mechanism 10 in the first room 51. Meanwhile, the filled fireworks cylinder on the ring-shaped conveying mechanism 10 can be output from the first room 51 to the third room 53 by the discharging assembly 30. Therefore, the operator only needs to operate in the third room 53 regardless of feeding or discharging, and the operator is located in the room outside the filling device and the compacting device, so that the safety risk is smaller.

[0049] In some technical solutions, the first isolation wall 54 is made of reinforced concrete structure, and the second isolation wall 55 is made of masonry structure. The reinforced concrete structure of the first isolation wall 54 can enhance the protection ability, so as to avoid the secondary accidents caused by the influence of the military nitre and the bright bead placed in the second room 52 on the first room.

[0050] Based on the above description of the embodiments of the present application, the production line for filling and compacting the spout-shaped fireworks comprises the ring-shaped conveying mechanism, which is configured to convey the fireworks cylinder in a ring shape. The gold powder filling device, the first compacting device, the military nitre filling device, the bright bead filling device, and the second compacting device are arranged along the ring-shaped conveying mechanism. The gold powder filling device, the first compacting device, the military nitre filling device, the bright bead filling device, and the second compacting device can sequentially fill the gold powder, compact the material for the first time, fill the military nitre, fill the bright bead, and compact the material for the second time on the fireworks cylinder every time the fireworks cylinder runs a circle. Therefore, the above-mentioned devices can realize the automatic multi-layer filling of the fireworks cylinder through the circular conveying, and the efficiency is high. Moreover, the operator does not need to approach the filling device and the compacting device, so that the safety risk is small.

[0051] In the above embodiments of the present application, the description of each embodiment has its own emphasis, and the parts not described in detail in a certain embodiment can be referred to the related description of other embodiments.

[0052] Moreover, the terms "first", "second", etc. are used herein only to describe different instances, and do not imply or suggest relative importance or a number of indicated technical features.
