[0104] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0105] This invention discloses a fireworks assembly machine, such as... Figure 1-32 As shown, it includes: a feeding conveyor line 1, a discharging conveyor line 2, a charging platform 3 and a rotating platform 4. The charging platform 3 is equipped with a first charging structure 5, a second charging structure 6, a third charging structure 7 and a fourth charging structure 8 in sequence along the circumference of the rotating platform 4. Two stamping mechanisms 9 are installed on the charging platform 3. The firework paper cakes 10 assembled and processed by the firework assembly machine are loaded through the carrier 100.

[0106] The feeding conveyor line 1 and the unloading conveyor line 2 are arranged in parallel on one side of the charging platform 3. Two adjacent connecting lines 200 are installed on the charging platform 3. One connecting line 200 is used to feed the firework paper cake 10 conveyed by the feeding conveyor line 1 to the rotating platform 4, and the other connecting line 200 is used to unload the assembled firework paper cake 10 on the rotating platform 4 to the unloading conveyor line 2.

[0107] The rotating platform 4 is used to drive the firework cake 10 to rotate so that the firework assembly machine can perform corresponding assembly operations on it; the first charging structure 5 is used to fill the firework propellant into the firework cake 10, the second charging structure 6 is used to fill the firework effect powder into the firework cake 10, the third charging structure 7 is used to fill the firework isolation sawdust into the firework cake 10, and the fourth charging structure 8 is used to fill the firework sealing sawdust into the firework cake 10.

[0108] One stamping mechanism 9 is used to stamp the firework cake 10 after it has been filled with firework effect powder, and the other stamping mechanism 9 is used to stamp the firework cake 10 after it has been filled with firework sealing sawdust. In the specific implementation process, the firework assembly machine is equipped with four detection components. The four detection components are used to detect the working status of the first charge structure 5, the second charge structure 6, the third charge structure 7, and the fourth charge structure 8, respectively. The detection components include a detection camera and a detection light source, and the detection light source is used to provide illumination to the detection camera.

[0111] like Figure 1-4 As shown, a first blocking component 14 is installed at one end of the feeding frame 11 near the charging platform 3. The first blocking component 14 is used to block the material conveyed by the feeding roller 12. It should be noted that, through the blocking effect of the first blocking component 14, the firework paper cakes 10 on the feeding roller 12 can be fed sequentially.

[0112] like Figure 3 and Figure 4As shown, the first blocking assembly 14 includes a first blocking cylinder 141 and a first blocking plate 142. The first blocking cylinder 141 is used to drive the first blocking plate 142 to extend and retract in a direction perpendicular to the axial direction of the feeding frame 11. In specific implementation, the number of the first blocking cylinder 141 and the first blocking plate 142 is set to four, arranged in two rows and two columns, so that the firework paper cakes 10 on the feeding roller 12 can be fed sequentially.

[0113] like Figure 1-5 As shown, the feeding conveyor line includes a feeding frame 21, feeding rollers 22, and a feeding motor 23. Several feeding rollers 22 are rotatably connected to the feeding frame 21, and the feeding motor 23 drives the feeding rollers 22 to rotate. It should be noted that the feeding motor 23 drives the feeding rollers 22 to rotate, moving the filled fireworks to the feeding position.

[0114] like Figure 3-5 As shown, a second blocking component 24 is installed at one end of the feeding frame 21 near the charging platform 3. The second blocking component 24 is used to block the material conveyed by the feeding roller 22. It should be noted that the second blocking component 24 acts as a blocking component, allowing the loaded fireworks to be fed and conveyed sequentially.

[0115] like Figure 3-5 As shown, the second blocking assembly 24 includes a second blocking cylinder 241 and a second blocking plate 242. The second blocking cylinder 241 is mounted on the feeding frame 21 and is used to drive the second blocking plate 242 to extend and retract in a direction perpendicular to the axial direction of the feeding frame 21. In specific implementation, there are four of each of the second blocking cylinders 241 and the second blocking plates 242, arranged in two rows and two columns, which allows the loaded fireworks to be fed and transported sequentially.

[0116] like Figure 15 , Figure 31 and Figure 32 As shown, the charging platform 3 includes a charging base plate 31, charging rods 32, and a charging top plate 33. There are five charging rods 32. One end of each charging rod 32 is fixedly connected to the charging base plate 31, and the other end is fixedly connected to the charging top plate 33. Each charging rod 32 is equipped with a locking assembly 34, and a charging support plate 35 is installed on the locking assembly 34. The charging support plate 35 is used to install the first charging structure 5, the second charging structure 6, the third charging structure 7, and the fourth charging structure 8. It should be noted that by setting up the charging platform 3, the first charging structure 5, the second charging structure 6, the third charging structure 7, and the fourth charging structure 8 can be integrated and installed, shortening the material transfer time between charging stations, reducing the space occupied by the equipment, and significantly improving the assembly efficiency of fireworks.

[0117] like Figure 31 and Figure 32 As shown, the locking assembly 34 includes a first locking buckle 341 and a second locking buckle 342 respectively fastened to the outer wall of the charge rod 32. The first locking buckle 341 and the second locking buckle 342 are detachably connected. The charge support plate 35 is fixedly connected to the first locking buckle 341 and the second locking buckle 342 respectively. A locking rib plate 343 is fixedly provided on one side of the second locking buckle 342, and the locking rib plate 343 is fixedly connected to the charge support plate 35. It should be noted that by setting the locking assembly 34, the first charge structure 5, the second charge structure 6, the third charge structure 7 and the fourth charge structure 8 can be installed at different heights on the charge rod 32 according to the size of the firework paper cake 10, so as to improve its processing adaptability.

[0118] like Figure 31 and Figure 32 As shown, several pulleys 36 are installed at the bottom of the charging base plate 31, and a support seat 37 for supporting the charging base plate 31 is threadedly connected to the charging base plate 31. It should be noted that the pulleys 36 facilitate the movement of the charging platform 3; the support seat 37 supports the charging platform 3, and when the support seat 37 contacts the ground, it can prevent the pulleys 36 from rolling, so that the charging platform 3 is placed stably on the ground.

[0119] like Figure 1 and Figure 15 As shown, the rotating platform 4 includes a rotating disk 41 and a rotating motor 42. The rotating disk 41 is rotatably connected to the loading platform 3, and the rotating motor 42 is mounted on the loading platform 3. The rotating motor 42 drives the rotating disk 41 to rotate. The rotating disk 41 is provided with placement stations 411 for placing materials. In specific implementation, there are six placement stations 411, one corresponding to the loading station, another to the unloading station, and the remaining four to the loading station.

[0120] like Figure 1 , Figure 10 and Figure 15 As shown, the rotary disk 41 has a notch 412 corresponding to the placement station 411. It should be noted that the notch 412 facilitates the raising and lowering of the rotary disk 41 and prevents the rotary disk 41 from interfering with the movement of the transmission component 202.

[0121] like Figure 15 As shown, the rotary disk 41 is equipped with a limiting component 43, which is used to limit the rotation of the material placed on the workstation 411.

[0122] like Figure 15As shown, the limiting component 43 includes a limiting cylinder 431 and a limiting block 432. The limiting cylinder 431 is fixedly installed on one side of the placement station 411, and the telescopic rod of the limiting cylinder 431 is fixedly connected to the limiting block 432. It should be noted that there are two limiting cylinders 431 and two limiting blocks 432 on each placement station 411. The limiting cylinder 431 drives the limiting block 432 to extend and retract, and the limiting block 432 abuts against the second carrier rod 102, limiting and fixing the firework paper cake 10 on the placement station 411 to prevent it from being rotated and detached.

[0123] like Figure 2 and Figure 9 As shown, the connecting line 200 includes a connecting base plate 201 rotatably connected to the loading platform 3. A transmission component 202 is slidably connected to the connecting base plate 201. A connecting cylinder 203 is mounted on the connecting base plate 201 to drive the transmission component 202 to move vertically. A connecting motor 204 is mounted on the loading platform 3 to drive the connecting base plate 201 to rotate. It should be noted that when one of the connecting lines 200 is connecting and loading material, the rotation of the connecting motor 204 moves the transmission component 202 to a suitable position; the driving action of the connecting cylinder 203 lifts the transmission component 202 to the receiving position, the material moves onto the transmission component 202, and then the connecting cylinder 203 lowers the material. The transmission component 202 drives the material to move, thus loading the material into the placement station 411.

[0124] like Figure 2 and Figure 9 As shown, the transmission assembly 202 includes a transmission frame 2021 that is slidably connected to the connecting base plate 201. A transmission belt 2022 is wound on the transmission frame 2021, and a transmission motor 2023 for driving the transmission belt 2022 to move is also installed on the transmission frame 2021.

[0125] like Figure 2 and Figure 9 As shown, a connecting baffle 2024 is fixedly installed on the conveyor frame 2021. It should be noted that the connecting baffle 2024 serves to block and prevent materials from falling off the conveyor assembly 202.

[0126] like Figure 1-14 As shown, the first charge structure 5 includes a first charge substrate 51, on which a first unloading plate 52, a first sealing plate 53 and a first dispensing plate 54 are sequentially mounted.

[0127] The first feeding plate 52 is equipped with a plurality of first feeding holes 521, the first sealing plate 53 is equipped with a plurality of first through holes 531 corresponding to the first feeding holes 521, and the first dividing plate 54 is provided with first dividing holes 541 corresponding to the first feeding holes 521.

[0129] like Figure 11-14 As shown, the first charging mechanism 55 includes a first loading seat 551 slidably connected to the first charging base plate 51. A first loading funnel 552 for receiving fireworks propellant is fixedly mounted on the first loading seat 551. A first loading motor 553 for driving the first loading seat 551 to move linearly is mounted on the first charging base plate 51. It should be noted that the first loading motor 553 drives the first loading seat 551 to move linearly, thereby moving the first loading funnel 552 and loading the fireworks propellant into the dispensing hole.

[0130] like Figure 11-14 As shown, a first brush 554 is fixedly installed on the first loading seat 551. It should be noted that there are two first brushes 554. The first brushes 554 abut against the first material distribution plate 54. By setting the first brushes 554, it can be ensured that when the first loading funnel 552 moves, the fireworks propellant is between the two first brushes 554, which facilitates loading and recycling.

[0131] like Figure 11-14 As shown, it also includes a first lifting assembly 57, which is used to drive the first propellant base plate 51 to move up and down in the vertical direction. It should be noted that, through the lifting action of the first lifting assembly 57, the first feeding plate 52 comes into contact with the firework cake 10. When the first telescopic cylinder 56 drives the first sealing plate 53 to move telescopically, the first through hole 531 communicates with the first feeding hole 521. The firework propellant in the dispensing hole enters the firework cake 10 through the first through hole 531 and the first feeding hole 521 in sequence, realizing the loading of the firework propellant.

[0132] like Figure 11-14 As shown, a first downward guide plate 58 is fixedly installed at the bottom of the first propellant base plate 51. It should be noted that the first downward guide plate 58 plays a downward guiding role, which facilitates the precise docking of the first feeding plate 52 with the firework paper cake 10, so as to achieve precise loading of the firework propellant.

[0133] like Figure 11-14As shown, the first lifting assembly 57 includes a first lifting base plate 571. The first propellant loading base plate 51 is slidably connected to the first lifting base plate 571 via a first lifting column 572. A first lifting cylinder 573 for driving the first propellant loading base plate 51 to lift is mounted on the first lifting base plate 571. It should be noted that the lifting action of the first lifting cylinder 573 causes the first propellant loading base plate 51 to move the first feeding plate 52. When the first feeding plate 52 contacts the fireworks paper cake 10, it facilitates the loading of fireworks propellant.

[0134] like Figure 1-22 As shown, the second charge structure 6 includes a second screening mechanism 61 and a second discharge mechanism 62. The second screening mechanism 61 is used to screen out a preset number of firework effect charges and provide them to the second discharge mechanism 62.

[0135] The second material leakage mechanism 62 includes a second material leakage plate 621. A second material discharge plate 622, a second sealing plate 623, and a second material leakage guide plate 624 are sequentially installed on the second material leakage plate 621. The second material discharge plate 622 is provided with a plurality of second material discharge holes 6221.

[0136] A second telescopic cylinder 625 is installed at one end of the second material leakage plate 621. The second telescopic cylinder 625 is used to drive the second sealing plate 623 to move telescopically so that the second through hole 6231 is connected to or offset from the second discharge hole 6221. The second discharge hole 6221 is used to discharge the firework effect powder into the firework paper cake 10 to be filled.

[0137] It should be noted that the firework effect powder is a bright bead; the second screening mechanism 61 screens out a preset number of firework effect powders and provides them to the second discharge guide plate 624 of the second discharge mechanism 62. When the second telescopic cylinder 625 drives the second sealing plate 623 to move telescopically, the second through hole 6231 communicates with the second discharge hole 6221. The firework effect powder in the second discharge hole 6241 enters the firework paper cake 10 through the second through hole 6231 and the second discharge hole 6221 in sequence, realizing the automatic filling of the firework effect powder.

[0138] like Figure 19-22As shown, the second material leakage mechanism 62 further includes a second movable base plate 6261, a second movable cylinder 6262, a second lifting base plate 6271, and a second lifting cylinder 6272. The second movable cylinder 6262 is connected to the second movable base plate 6261, the second lifting base plate 6271 is slidably connected to the second movable base plate 6261, the second lifting cylinder 6272 is fixedly installed on the second lifting base plate 6271, the telescopic rod of the second lifting cylinder 6272 is fixedly connected to the second material leakage plate 621, and the second material leakage plate 621 is slidably connected to the second lifting base plate 6271 through the second guide post. It should be noted that the second lifting base plate 6271 is moved by the second moving cylinder 6262 to facilitate the movement of the second material discharge guide plate 624 to the second screening mechanism 61 for material receiving. After receiving the material, the second material discharge guide plate 624 is moved to the top of the firework paper cake 10. The second feeding plate 622 is raised and lowered by the second lifting cylinder 6272 so that the second feeding plate 622 contacts the firework paper cake 10. The firework effect powder in the second material discharge hole 6241 enters the firework paper cake 10 through the second through hole 6231 and the second feeding hole 6221 in sequence, realizing the automatic filling of the firework effect powder.

[0139] like Figure 19-22 As shown, a second downward guide plate 628 is fixedly installed at the bottom of the second discharge plate 621. It should be noted that the second downward guide plate 628 serves as a downward guide, facilitating precise docking between the second discharge plate 622 and the firework cake 10, thereby achieving precise filling of the firework effect powder.

[0140] like Figure 19-22 As shown, the second screening mechanism 61 includes a screening column 611, a screening frame 612 rotatably connected to the screening column 611, a screening hole 6121 corresponding to the second discharge hole 6241 on the screening frame 612, a screening motor 613 for driving the screening frame 612 to rotate mounted on the screening column 611, and a first opening and closing component 614 mounted on the bottom of the screening frame 612 for adjusting the opening and closing of the bottom of the screening hole 6121. It should be noted that the screening motor 613 drives the screening frame 612 to rotate, causing the pyrotechnic effect powder inside the screening frame 612 to enter the screening hole 6121, and the opening and closing action of the first opening and closing component 614 allows the pyrotechnic effect powder to be discharged into the second discharge hole 6241 of the second discharge guide plate 624.

[0141] like Figure 19-22As shown, the first opening and closing assembly 614 includes a first opening and closing plate 6141 and a first opening and closing cylinder 6142. The first opening and closing cylinder 6142 is fixedly connected to the screening frame 612. The telescopic rod of the first opening and closing cylinder 6142 is fixedly connected to the first opening and closing plate 6141. The first opening and closing plate 6141 is provided with a first opening and closing hole corresponding to the screening hole 6121. The first opening and closing cylinder 6142 is used to drive the first opening and closing plate 6141 to move linearly so that the first opening and closing hole communicates with or is offset from the screening hole 6121.

[0142] It should be noted that when the first opening and closing cylinder 6142 drives the first opening and closing plate 6141 to move, so that the first opening and closing hole communicates with the screening hole 6121, the fireworks effect powder in the screening hole 6121 leaks into the second leakage hole 6241 of the second leakage guide plate 624.

[0143] like Figure 19-22 As shown, a funnel chamber 6122 is provided at one end of the screening frame 612 relative to the screening hole 6121. A second opening and closing component 615 is provided on the screening frame 612, which is used to open and close the adjusting funnel chamber 6122. It should be noted that the funnel and the second opening and closing component 615 facilitate the temporary storage of fireworks effect powder.

[0144] like Figure 19-22 As shown, the second opening and closing assembly 615 includes a second opening and closing shaft 6151 rotatably connected to the screen frame 612. The second opening and closing shaft 6151 is fixedly connected to a second opening and closing door 6152 for separating the screen hole 6121 from the funnel chamber 6122. A second opening and closing motor 6153 for driving the second opening and closing shaft 6151 to rotate is installed on one side of the screen frame 612. It should be noted that by driving the second opening and closing shaft 6151 to rotate via the second opening and closing motor 6153, the second opening and closing door 6152 is rotated, allowing the pyrotechnic effect powder in the funnel chamber 6122 to roll into the screen hole 6121.

[0145] like Figure 19-22 As shown, a guide plate 616 is fixedly installed inside the sieve frame 612, and the guide plate 616 is arranged adjacent to the second discharge hole 6241. It should be noted that the guide plate 616 facilitates the smooth filling of the fireworks effect powder into the sieve hole 6121.

[0146] like Figure 1-28 As shown, the third loading structure 7 includes a third unloading base plate 71, a third unloading plate 72, a third dispensing plate 73, and a third loading mechanism 74. The third unloading base plate 71 is fixedly connected to the third unloading plate 72 and the third dispensing plate 73 respectively.

[0147] The third feeding plate 72 is provided with a plurality of third feeding holes 721. The third feeding holes 721 are used to feed the firework isolation sawdust provided by the third charging mechanism 74 into the firework cake 10. The third distributing plate 73 is provided with a third distributing hole 731 corresponding to the third feeding hole 721. The bottom of the third distributing plate 73 is provided with a third opening and closing component 75 for connecting or blocking the third feeding hole 721 and the third distributing hole 731.

[0148] The third charging mechanism 74 includes a third charging hopper 741, a third moving component 742, and a stirring component 743. The third charging hopper 741 is used to contain fireworks isolation sawdust. The third moving component 742 is used to drive the third charging hopper 741 and the stirring component 743 to move linearly. The stirring component 743 is used to stir the fireworks isolation sawdust in the third charging hopper 741.

[0149] It should be noted that the movement of the third moving component 742 drives the third charging hopper 741 to move, filling the firework isolation sawdust into the third distributing hole 731. Through the opening and closing of the third opening and closing component 75, the firework isolation sawdust in the third distributing hole 731 enters the firework paper cake 10 through the third feeding hole 721, thus realizing the filling of the firework isolation sawdust.

[0150] like Figure 23-28 As shown, the third opening and closing assembly 75 includes a third opening and closing plate 751 and a third opening and closing cylinder 752. The third opening and closing cylinder 752 is fixedly installed on the bottom of the third material distribution plate 73. The telescopic rod of the third opening and closing cylinder 752 is fixedly connected to the third opening and closing plate 751. The third opening and closing plate 751 is provided with a third opening and closing hole 7511 corresponding to the third discharge hole 721.

[0151] It should be noted that the third opening and closing plate 751 is driven to move linearly by the third opening and closing cylinder 752, so that the third opening and closing hole 7511 is connected to the third material distribution hole 731. The fireworks isolation sawdust in the third material distribution hole 731 enters the fireworks paper cake 10 through the third material discharge hole 721, thus realizing the filling of fireworks isolation sawdust.

[0152] like Figure 23-28 As shown, the third moving component 742 includes a third moving base plate 7421 slidably connected to the third unloading base plate 71. A third moving motor 7422 is mounted at one end of the third unloading base plate 71 for driving the third moving base plate 7421 to move linearly along the axial direction of the third unloading base plate 71. In a specific implementation, the third moving base plate 7421 is fixedly connected to the third loading hopper 741.

[0153] like Figure 23-28As shown, the stirring assembly 743 includes a stirring cylinder 7431, a stirring connecting rod 7432, and a stirring element 7433. The stirring element 7433 is rotatably connected inside the third charge hopper 741. One end of the stirring connecting rod 7432 is hinged to the stirring element 7433, and the other end of the stirring connecting rod 7432 is hinged to the telescopic rod of the stirring cylinder 7431. It should be noted that the telescopic action of the stirring cylinder 7431 causes the stirring element 7433 to swing, thus stirring the fireworks isolation sawdust inside the third charge hopper 741 and preventing blockage.

[0154] like Figure 23-28 As shown, it also includes a third lifting assembly 76, which includes a third lifting base plate 761, a third lifting rod 762, and a third lifting cylinder 763. One end of the third lifting rod 762 is fixedly connected to the third feeding base plate 71, and the third lifting rod 762 is slidably connected to the third lifting base plate 761. The third lifting cylinder 763 is mounted on the third lifting base plate 761, and the telescopic rod of the third lifting cylinder 763 is fixedly connected to the third feeding base plate 71. It should be noted that the third lifting cylinder 763 drives the third feeding base plate 71 to move up and down, which facilitates the third feeding plate 72 to move up and down. When the third feeding plate 72 contacts the fireworks paper cake 10, it is convenient to fill it with fireworks isolation sawdust.

[0155] like Figure 23-28 As shown, a third downward guide plate 77 is fixedly installed at the bottom of the third feeding plate 72. It should be noted that the third downward guide plate 77 plays a downward guiding role, which facilitates the precise docking of the third feeding plate 72 with the fireworks paper cake 10, so as to achieve precise filling of fireworks isolation sawdust.

[0156] like Figure 26As shown, the third loading mechanism 74 also includes a cleaning assembly 744, which includes a first cleaning brush 7441, a second cleaning brush 7442, a cleaning frame 7443, and a cleaning cylinder 7444. The first cleaning brush 7441 and the second cleaning brush 7442 are distributed on opposite sides of the third loading hopper 741. The cleaning cylinder 7444 is fixedly connected to the cleaning frame 7443 and is used to drive the first cleaning brush 7441 and the second cleaning brush 7442 to perform asynchronous lifting and lowering movements. It should be noted that the first cleaning brush 7441 is close to the third distribution hole 731. When it is necessary to fill the third distribution hole 731 with fireworks isolation sawdust, the cleaning cylinder 7444 drives the first cleaning brush 7441 and the second cleaning brush 7442 to perform asynchronous lifting and lowering movements. This causes the first cleaning brush 7441 to rise and disengage from the third distribution plate 73, while the second cleaning brush 7442 descends and comes into contact with the third distribution plate 73. The cleaning action of the second cleaning brush 7442 facilitates the cleaning of fireworks isolation sawdust into the third distribution hole 731. Conversely, the cleaning action of the first cleaning brush 7441 can also be used to recycle fireworks isolation sawdust.

[0157] like Figure 1-30 As shown, the fourth charge structure 8 includes a fourth feeding base plate 81 and a fourth charge mechanism 82. The fourth feeding base plate 81 is fixedly mounted with a fourth feeding plate 83. The fourth feeding plate 83 is provided with a plurality of fourth feeding holes 831. The fourth charge mechanism 82 is used to fill the fireworks sealing sawdust into the fourth feeding holes 831.

[0158] It should be noted that the fourth feeding plate 83 is in contact with the firework paper cake 10. The fourth loading mechanism 82 fills the firework sealing sawdust into the fourth feeding hole 831, and then into the firework paper cake 10 to realize the filling of the firework sealing sawdust. Then, it is pressed and compacted by a stamping mechanism 9.

[0159] like Figure 29 and Figure 30 As shown, it also includes a fourth lifting assembly 84, which includes a fourth lifting base plate 841 and a fourth lifting cylinder 842. The fourth feeding base plate 81 is slidably connected to the fourth lifting base plate 841 via a fourth lifting rod 843, and the telescopic rod of the fourth lifting cylinder 842 is fixedly connected to the fourth feeding base plate 81. It should be noted that the fourth lifting cylinder 842 drives the fourth feeding base plate 81 to lift, thereby driving the fourth feeding plate 83 to lift. When the fourth feeding plate 83 rises, it disengages from the fireworks paper cake 10, making it easier for the fireworks paper cake 10 to be rotated and moved to the next work station. When the fourth feeding plate 83 descends and contacts the fireworks paper cake 10, it facilitates the filling of fireworks sealing sawdust.

[0160] like Figure 29 and Figure 30 As shown, a fourth pressing guide plate 85 corresponding to the fourth feeding plate 83 is installed at the bottom of the fourth feeding base plate 81. It should be noted that the fourth pressing guide plate 85 plays a pressing and guiding role, which facilitates the precise docking of the fourth feeding plate 83 with the fireworks paper cake 10, so as to achieve precise filling of fireworks sealing sawdust.

[0161] like Figure 1-18 As shown, the stamping mechanism 9 includes a stamping assembly 91 and a stamping motor 92. The stamping motor 92 is connected to the stamping assembly 91 by a steel wire rope 93. The stamping motor 92 is used to drive the stamping assembly 91 to move up and down in the vertical direction.

[0162] like Figure 16-18 As shown, the stamping assembly 91 includes a stamping frame 911, on which several stamping rods 912 are mounted. The stamping rods 912 are used to stamp the firework paper cake 10. In a specific implementation, the stamping assembly 91 also includes a stamping limiting plate 913. The stamping rods 912 pass through the stamping limiting plate 913, and the stamping limiting plate 913 limits the stamping, allowing the stamping rods 912 to accurately stamp the firework paper cake 10.

[0163] like Figure 16-18 As shown, a stamping spring is installed on the stamping frame 911 to buffer the stamping motion of the stamping rod 912. It should be noted that the buffering effect of the stamping spring prevents damage to the firework paper cake 10 due to excessive impact force from the stamping rod 912.

[0164] The specific processing flow of the fireworks assembly machine is as follows: Several fireworks paper cakes 10 to be filled are sequentially transported through the feeding conveyor line 1. One of the connecting lines 200 feeds the fireworks paper cakes 10 on the feeding conveyor line 1 to the placement station 411 of the rotating platform 4 in sequence, and limits and fixes them through the limiting component 43 to prevent the fireworks paper cakes 10 from being rotated and detached.
