Description

Technical Field

[0001] This invention relates to the field of paper tube fireworks production technology, specifically an automated filling device for paper tube fireworks. Background Technology

[0002] Paper tube fireworks are a type of pyrotechnic product, typically consisting of a paper tube containing pyrotechnic agents and components. These fireworks are usually cylindrical and can produce various beautiful effects when burned, such as colored smoke and flame jets. As a traditional celebratory and entertainment item, the production process of paper tube fireworks involves several complex steps. The filling stage is particularly crucial, directly determining the quality and safety performance of the fireworks product.

[0003] While existing filling equipment has made some progress in design and function, it still requires significant manual intervention in many aspects of actual operation. This reliance on manual intervention limits the automation level of the equipment, preventing the overall production line from reaching its full potential. This not only affects the filling speed of paper tube fireworks but also leads to higher labor costs. Furthermore, manual operation is often subject to significant errors and uncertainties, especially in the precise control required during filling, such as controlling the propellant and placing the paper pieces. These human factors can negatively impact product quality, resulting in inconsistencies.

[0004] Therefore, an automated paper tube fireworks filling device is needed to solve the above problems. Summary of the Invention

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] This invention provides an automated filling device for paper tube fireworks, such as... Figures 1-9 As shown, the filling equipment includes a first conveyor belt mechanism 1 for feeding paper tubes, a loading mechanism 2 fixedly disposed at the discharge end of the first conveyor belt mechanism 1 for loading propellant into the paper tubes, a second conveyor belt mechanism 3 fixedly disposed on one side of the loading mechanism 2 and connected to the discharge end of the first conveyor belt mechanism 1, a paper-feeding mechanism 4 fixedly disposed at one end of the second conveyor belt mechanism 3 away from the first conveyor belt mechanism 1 for filling the lower layer of paper sheets into the paper tubes, a third conveyor belt mechanism 5 fixedly disposed on one side of the paper-feeding mechanism 4 away from the second conveyor belt mechanism 3, a firework-loading mechanism 6 fixedly disposed at one end of the third conveyor belt mechanism 5 away from the paper-feeding mechanism 4 for loading firework into the paper tubes, and a fixed... The fourth conveyor belt mechanism 7 is located on the side of the fireworks loading mechanism 6 away from the third conveyor belt mechanism 5; the paper loading mechanism 8 is fixedly located on the end of the fourth conveyor belt mechanism 7 away from the fireworks loading mechanism 6 for loading the upper layer of paper into the paper tube; and the unloading module 9 is fixedly located on the side of the paper loading mechanism 8 away from the fourth conveyor belt mechanism 7 for unloading the fireworks paper tube. The unloading module 9 includes a fifth conveyor belt mechanism 91 connected to the paper loading mechanism 8, a fifth feeding component 92 fixedly located on the end of the fifth conveyor belt mechanism 91 away from the paper loading mechanism 8, and an unloading conveyor belt mechanism 93 fixedly located on the side of the fifth feeding component 92 and connected to the fifth conveyor belt mechanism 91.

[0042] In use, the first conveyor belt mechanism 1 is activated, and the paper tubes to be filled are placed sequentially at the feed end of the first conveyor belt mechanism 1. Through the conveying of the first conveyor belt mechanism 1, the paper tubes to be filled are sequentially conveyed to the area below the propellant loading mechanism 2. After the paper tubes reach the area below the propellant loading mechanism 2, the propellant loading mechanism 2 automatically loads the propellant into the conveyed paper tubes. Then, the paper tubes filled with propellant are conveyed to the second conveyor belt mechanism 3. Simultaneously, the propellant loading mechanism 2 continues to fill the paper tubes conveyed by the first conveyor belt mechanism 1. The paper tubes conveyed to the second conveyor belt mechanism 3 are then conveyed to the paper-feeding mechanism 4. After the paper tubes reach the area below the paper-feeding mechanism 4, the paper-feeding mechanism 4 automatically fills the area above the propellant in the paper tube with the lower layer of paper. Afterwards, the paper tubes filled with the lower layer of paper are then conveyed again... The paper tubes are then conveyed to the third conveyor belt mechanism 5. Through this conveying action, the paper tubes are automatically transported to the fireworks loading mechanism 6. When the paper tubes reach the lower position of the fireworks loading mechanism 6, the fireworks loading mechanism 6 automatically loads the fireworks onto the top layer of paper on the paper tube. Next, the paper tubes are conveyed to the fourth conveyor belt mechanism 7. Through this conveying action, the paper tubes are automatically transported to the paper-loading mechanism 8. When the paper tubes reach the lower position of the paper-loading mechanism 8, the paper-loading mechanism 8 automatically loads the upper layer of paper onto the fireworks on the paper tube. Finally, all the filled firework paper tubes are conveyed to the fifth conveyor belt mechanism 91. Driven by the fifth feeding component 92, the filled paper tubes on the fifth conveyor belt mechanism 91 are smoothly conveyed to the unloading conveyor belt mechanism 93 for unloading.

[0043] Specifically, the loading mechanism 2 includes a first frame 21 fixedly mounted at the discharge end of the first conveyor belt mechanism 1, a clamping cylinder assembly 22 mounted on the first frame 21, a mounting plate 23 fixedly mounted on the first frame 21 at a position above the clamping cylinder assembly 22, a filling hole opened on the mounting plate 23, and a gunpowder filling machine fixedly mounted on the mounting plate 23 and communicating with the filling hole; wherein, the clamping cylinder assembly 22 includes clamping plates 221 symmetrically arranged on the first frame 21 at a position above the first conveyor belt mechanism 1, a first servo electric cylinder 222 respectively fixedly mounted on the first frame 21 for driving the two clamping plates 221 to move closer or further apart, and telescopic rods 223 symmetrically arranged on both sides of the first servo electric cylinder 222, and the stator of the telescopic rod 223 The end and the movable end are fixedly connected to the first frame 21 and the clamping plate 221 respectively. When the first conveyor belt mechanism 1 conveys the paper tube to be filled to the clamping tube assembly 22, the two first servo electric cylinders 222 set on the first frame 21 will stably push the two clamping plates 221 closer to each other under the guidance of their corresponding telescopic rods 223, and clamp the two sides of the paper tube to be filled to ensure the stability of the paper tube filling process. At the same time, the gunpowder filler will directly and smoothly fill the gunpowder into each paper tube through the filling hole of the mounting plate 23. After the gunpowder filling is completed, the first servo electric cylinder 222 will push the clamping plate 221 away from the paper tube, release the clamping of the paper tube, so that the paper tube filled with gunpowder can continue to be conveyed to the next process through the first conveyor belt mechanism 1.

[0044] In addition, a first feeding assembly 11 is fixedly provided at the connection between the first conveyor belt mechanism 1 and the second conveyor belt mechanism 3; the first feeding assembly 11 includes a fixed frame 111 fixedly provided on the first conveyor belt mechanism 1, a push plate 112 that slides laterally on the first conveyor belt mechanism 1, a first lead screw 113 rotatably connected to the fixed frame 111 and passing through one side of the push plate 112, a first motor 114 fixedly installed on one side of the fixed frame 111 for driving the first lead screw 113 to rotate, and a first guide rod provided on both sides of the first lead screw 113 and passing through the push plate 112. 115. The first lead screw 113 is screwed to the push plate 112. The push plate 112 is slidably mounted on the first guide rod 115. The first guide rod 115 is fixedly mounted on the fixed frame 111. After the propellant is filled, the paper tube will continue to be conveyed to the push plate 112 under the conveying action of the first conveyor belt mechanism 1. Then, the first motor 114 will drive the first lead screw 113 to rotate. At this time, under the guiding action of the first guide rod 115, the push plate 112 screwed to the first lead screw 113 will automatically push the paper tube filled with propellant to the second conveyor belt mechanism 3 for conveying.

[0045] More specifically, the paper loading mechanism 4 includes a second frame 41 fixedly disposed between the second conveyor belt mechanism 3 and the third conveyor belt mechanism 5; a first support plate 42 fixedly mounted on the second frame 41 and connected to the second conveyor belt mechanism 3 and the third conveyor belt mechanism 5; a second feeding assembly 43 fixedly disposed on the second frame 41 near the second conveyor belt mechanism 3 and the third conveyor belt mechanism 5 and located above the first support plate 42; a first pushing assembly 44 disposed on the first support plate 42; a paper stamping assembly 45 fixedly disposed on one side of the second feeding assembly 43; and a paper conveying assembly 45 fixedly disposed on the side of the paper stamping assembly 45 away from the second feeding assembly 43. 6; After the second conveyor belt mechanism 3 conveys the paper tube filled with propellant to the second frame 41, the second feeding component 43 will push the conveyed paper tube to the first pushing component 44 of the first support plate 42 in sequence. Then, the first pushing component 44 will push the paper tube to the bottom of the paper stamping component 45. After the paper tube reaches the bottom of the paper stamping component 45, the paper stamping component 45 will directly stamp and fill the paper tube with the paper conveying component 46. After the bottom layer of paper is filled, the first pushing component 44 will continue to push the paper tube back to the bottom of the second feeding component 43. Finally, the second feeding component 43 will push the paper tube filled with the bottom layer of paper to the third conveyor belt mechanism 5.

[0046] Furthermore, the first feeding assembly 44 includes a slide plate 441 that slides laterally on the second frame 41, a second lead screw 442 that is rotatably connected to the bottom of the second frame 41 and passes through the bottom end of the slide plate 441, a second motor 443 that is fixedly installed on the second frame 41 for driving the second lead screw 442 to rotate, and a second guide rod 444 that is disposed on both sides of the second lead screw 442 and passes through the slide plate 441. The second guide rod 444 is fixedly connected to the second frame 41, the slide plate 441 is slidably sleeved on the second guide rod 444, and the slide plate 441 is screwed to the second lead screw 442. After the second feeding assembly 43 pushes the paper tube onto the slide plate 441, the second motor 443 will drive the second lead screw 442 to rotate. At this time, under the guidance of the second guide rod 444, the second lead screw 442 will drive the paper tube carried on the slide plate 441 to move stably to the bottom of the paper sheet stamping assembly 45 for filling.

[0047] It should be noted that the second pusher assembly 64 has the same structure and working principle as the first pusher assembly 44.

[0048] Furthermore, the paper stamping assembly 45 includes a fixed plate 451 fixedly installed on the side of the second frame 41 corresponding to the second feeding assembly 43, a stamping hole opened on the fixed plate 451, a frame 452 fixedly installed above the stamping hole on the fixed plate 451, a stamping plate 453 that moves longitudinally between the frame 452 and the fixed plate 451, a first cylinder 454 fixedly installed on the frame 452 for driving the stamping plate 453 to move, and slide rods 455 disposed on both sides of the first cylinder 454 and passing through the frame 452. The rod 455 is slidably connected to the frame 452, and the bottom end of the rod 455 is fixedly connected to the stamping plate 453. After the slide plate 441 pushes the paper tube to the bottom of the paper stamping assembly 45, the first cylinder 454, guided by the rod 455, can stably drive the stamping plate 453 to descend and stamp the paper sheet conveyed between the stamping plate 453 and the fixed plate 451. Then, through the setting of the stamping hole on the fixed plate 451, the stamped paper sheet can be smoothly stamped and filled into the corresponding paper tube from the stamping hole, thereby automatically completing the filling of the lower layer of paper sheet.

[0049] Furthermore, the paper conveying assembly 46 includes a liftable bracket 461 fixedly mounted on the end of the second frame 41 away from the second feeding assembly 43, an active roller 462 rotatably connected to the liftable bracket 461, and a conveying roller 463 and a winding roller 464 symmetrically arranged on both sides of the fixed plate 451. The conveying roller 463 and the winding roller 464 are rotatably connected to the second frame 41. When a filling operation is required, the paper to be filled can be fixed on the active roller 462. Then, one end of the paper is passed through the conveying roller 463, the fixed plate 451, and the winding roller 464 in sequence. Therefore, when the paper tube reaches below the fixed plate 451, the paper can be continuously conveyed to the space between the fixed plate 451 and the stamping plate 453 by the conveying roller 463 and stamped for filling. The stamped paper will be automatically wound up by the winding action of the winding roller 464.

[0050] It should be noted that the paper loading mechanism 8 and the paper unloading mechanism 4 have the same structure and working principle, but the paper punching and filling height of the paper loading mechanism 8 is higher than that of the paper punching and filling height of the paper unloading mechanism 4.

[0051] More specifically, the fireworks loading mechanism 6 includes a third frame 61 fixedly mounted on the end of the third conveyor belt mechanism 5 away from the second frame 41; a second support plate 62 fixedly mounted on the third frame 61 and connected to the third conveyor belt mechanism 5 and the fourth conveyor belt mechanism 7; a third feeding assembly 63 fixedly mounted on the third frame 61 near the end of the third conveyor belt mechanism 5 and located above the second support plate 62; a second pushing assembly 64 mounted on the second support plate 62; a feeding assembly 65 fixedly mounted on the side of the third feeding assembly 63 near the fourth conveyor belt mechanism 7; a fireworks module 66 fixedly mounted between the feeding assembly 65 and the third feeding assembly 63; a pressing assembly 67 positioned above the fireworks module 66; and a pressing assembly 67 fixedly mounted below the fireworks module 66 for pressing the second support plate 61 onto the third frame 41. The paper tube on the 2nd is guided to the fourth feeding component 68 on the fourth conveyor belt mechanism 7. Before the third conveyor belt mechanism 5 conveys the paper tube filled with the upper layer of paper to the third frame 61, the fireworks can be manually fed into the feeding component 65 and then fed into the fireworks module 66. When the third conveyor belt mechanism 5 conveys the paper tube to the third frame 61, the third feeding component 63 will push the paper tube onto the second pushing component 64 on the second support plate 62. Then, the second pushing component 64 will automatically push the paper tube to the bottom of the fireworks module 66. At this time, the pressing component 67 will press down the fireworks pre-filled in the fireworks module 66 and fill them directly onto the upper layer of paper on the paper tube. After filling, the fourth feeding component 68 will directly push the filled paper tube onto the fifth conveyor belt mechanism 91 for unloading.

[0052] It is worth noting that the feeding assembly 65 includes a hopper 651 fixedly installed on the side of the third frame 61 away from the fifth conveyor belt mechanism 91, a support frame 652 slidably installed on the third frame 61 at a position corresponding to the hopper 651 below it, a second cylinder 654 fixedly installed on the third frame 61 for driving the support frame 652 to move, a connecting frame 653 fixedly installed on the third frame 61 between the fireworks module 66 and the support frame 652, an inlet plate 655 slidably installed on the connecting frame 653, and a feed plate 655 fixedly installed on the third frame 61. 1. A servo cable chain driver 656 is used to drive the feed plate 655 to move. After the fireworks are manually fed into the hopper 651, the fireworks will automatically be fed onto the support frame 652. Then, the second cylinder 654 will push the support frame 652 to move and connect with the connecting frame 653. After the connecting frame 653 and the support frame 652 are connected, the servo cable chain driver 656 will drive the feed plate 655 to move on the connecting frame 653 and the support frame 652. At this time, the fireworks can be automatically pushed into the fireworks module 66 by pushing the feed plate 655.

[0053] It is also worth noting that the fireworks module 66 includes a fixed mold 661 fixedly disposed between the third feeding assembly 63 and the connecting frame 653, a flipping mold 662 rotatably connected to the third frame 61 at a position above the fixed mold 661, a connecting rod 663 hinged to one end of the flipping mold 662, and a third cylinder 664 fixedly installed on the third frame 61 for driving the flipping mold 662 to rotate. The piston rod of the third cylinder 664 is hinged to the other end of the connecting rod 663. During the process of the feeding plate 655 pushing the fireworks, the third cylinder 664 will push the connecting rod 663 to move. At this time, through the hinge of the connecting rod 663, the flipping mold 662 will automatically flip. Therefore, when the feeding plate 655 pushes the fireworks to the fireworks module 66, the flipping mold 662 has already flipped. Then, under the continued pushing action of the feeding plate 655, the fireworks will automatically be fed from the connecting frame 653 into the fixed mold 661.

[0054] It is worth noting that the pressing assembly 67 includes fixed rods 671 symmetrically arranged on both sides of the fixed mold 661, a top plate 672 fixedly installed on the top of the two fixed rods 671, a pressing plate 673 that moves longitudinally between the top plate 672 and the flipping mold 662, and a fourth cylinder 674 fixedly installed on the top plate 672 for driving the pressing plate 673 to move. The fixed rods 671 are fixedly connected to the third frame 61, and the two ends of the pressing plate 673 are slidably sleeved on the two fixed rods 671. When the paper tube is conveyed to the bottom of the fireworks module 66, the fourth cylinder 674 will automatically drive the pressing plate 673 to press down to the flipping mold 662. Then, through the continued pressing of the pressing plate 673, the fireworks in the fixed mold 661 will be automatically fed into the paper tube.

[0055] It should also be noted that the second feeding assembly 43, the third feeding assembly 63, the fourth feeding assembly 68, and the fifth feeding assembly 92 have the same structure and working principle as the first feeding assembly 11, and are used to ensure smooth transmission during the paper tube filling process.
