[0009] The inner tube conveyor belt group and the outer tube conveyor belt group overlap at the assembly machine position, and the assembly machine loads the firework inner tube into the combined firework tube.

[0010] Furthermore, it also includes a bead vibrating machine, which is arranged at the rear side of the charge loading machine and vibrates the bright beads and the opening powder loaded into the firework inner tube to make them uniform.

[0011] Furthermore, independent explosion-proof rooms are respectively provided around the bright bead adding machine, charge loading machine, charge launching machine and bead vibrating machine, and the unloading station is separated from other parts of the outer cylinder conveyor belt group by an explosion-proof wall.

[0012] Furthermore, the feed port of the charge machine is connected to a mixing barrel, and the oxidant, the reducing agent and the sulfur are respectively fed to the mixing barrel through screw conveyors; the raw materials of the oxidant and the reducing agent are separately arranged in the raw material room on the opposite side of the charge machine.

[0013] Furthermore, it also includes a second filler and a dust extractor, which are arranged behind the first filler in sequence, and the material filling nozzles of the first filler and the second filler can be inserted into the middle hole of the firework inner tube; the exhaust hood of the dust extractor can clean the debris on the top surface of the firework inner tube.

[0014] Furthermore, it also includes a packaging conveyor belt, the feeding end of which is connected to the unloading station, and the packaging conveyor belt is sequentially provided with a mounting machine and a labeling machine.

[0015] Furthermore, the main body of the inner cylinder tooling disk is a rectangular metal block, and a plurality of inner cylinder positioning holes are regularly arranged on the inner cylinder tooling disk and the arrangement method is consistent with that of the combined firework tube, and the firework inner cylinder is inserted into the vertically arranged inner cylinder positioning holes; and first clamping pits for facilitating positioning and clamping are provided on two opposite outer walls of the inner cylinder tooling disk.

[0016] Furthermore, a lower guard that can be horizontally displaced is also provided at the bottom of the inner cylinder tooling disk, and the two lower guards are symmetrically connected to the two ends of the inner cylinder tooling disk through a horizontal guide structure. The bottom plate of the lower guard is tightly attached to the bottom surface of the inner cylinder tooling disk, and the bottom plate is arranged with a plurality of spaced-apart baffles, which can cover and open the bottom opening of the inner cylinder positioning hole.

[0017] Furthermore, the two lower shields are tightened by tension springs, and push rods are horizontally arranged at the outer ends of the lower shields; and inclined guide plates for pushing the push rods are arranged on both sides of the lower pressure head of the assembly machine.

[0018] The present invention also discloses a production process for effect type combined fireworks, and uses any one of the above effect type combined fireworks production lines to produce effect type combined fireworks, comprising the following steps:

[0019] S1. Inner cylinder assembly: the inner cylinder conveyor belt group carries the inner cylinder tooling tray and the fireworks inner cylinder to complete the filling of bright beads, opening and filling of medicine, vibrating and tamping, filling of fillers, pressing and sealing in sequence;

[0020] S2, outer tube assembly: the outer tube conveyor belt group carries the outer tube tooling plate and the combined firework tube to first fill the propellant, then install the lower paper piece, and then assemble the firework inner tube that has been sealed in the above step S1 at the assembly machine station, and enter the unloading station after installing the paper piece.

[0021] Compared with the prior art, the beneficial technical effects of the present invention are:

[0022] The effect-type combined fireworks production line of the present invention provides an inner cylinder tooling tray and an outer cylinder tooling tray to assist in conveying the fireworks inner cylinder and the combined fireworks cylinder respectively, so as to facilitate accurate positioning at each station, ensure the accuracy of processes such as medicine filling and filling, and ensure accurate alignment of the two monomers at the assembly machine station for smooth assembly; the inner cylinder conveyor belt group and the outer cylinder conveyor belt group are combined at the assembly machine station to avoid the process of semi-finished inner cylinders entering and exiting the transit warehouse, with a high degree of automation, and improved production efficiency and safety factor.

[0023] In addition, by setting the vibrating bead machine at the rear side of the charge machine, the unpacking medicine and the bright beads can be mixed evenly, improving the fireworks display effect. By setting up an explosion-proof room, the dangerous workstations are isolated, and the safety performance of the production line is improved. By setting up separate raw material rooms for the raw materials of the oxidant and the reductant, and using a screw conveyor for transportation, the raw materials are mixed as they are fed, avoiding the dangers caused by large-scale mixed medicines, and the isolated and separate storage is safe. The conveying pipe is used to probe into the inner tube of the fireworks to charge the medicine, which reduces dust. Two filling machines are set up, and different fillers can be filled in at the same time to achieve better filling and sealing effects; by setting up a dust extractor, the debris on the top surface of the inner tube of the fireworks can be cleaned in time, which is convenient for subsequent sealing and assembly. By adding a packaging conveyor belt, a mounting machine and a labeling machine, the combined firework tube that has completed the internal operation can be directly processed into a finished product without further transportation, and can be directly stored in the finished product warehouse or shipped. By arranging a rubber plate between the inner tube mounting plate and the mounting cover plate, and by arranging a retaining edge head at the top of the mounting hole, the inner tube monomer of the fireworks can be prevented from escaping upward from the mounting hole, thereby avoiding the occurrence of empty shots. By arranging a plurality of regularly arranged outer tube combination mounting pits on the top surface of the outer tube tooling plate, and clamping a combination firework tube in each outer tube combination mounting pit, the inner tube monomer of the fireworks can be pressed and assembled simultaneously with a plurality of combination firework tubes, thereby improving production efficiency. By stacking the inner tube plate conveying mechanism and the outer tube plate conveying mechanism vertically and crosswise up and down, the inner tube tooling plate and the outer tube tooling plate are overlapped and aligned at the assembly machine station, thereby ensuring the press-fitting of the inner tube monomer of the fireworks. By setting the jacking assembly, it can be ensured that the outer tube tooling plate and the combination firework tube are lifted upward to the bottom of the workbench assembly before pressing in, so as to be seamlessly connected, thereby avoiding the inner tube monomer of the fireworks being pressed and unable to accurately enter the outer tube monomer. By setting the outer cylinder disc coarse limit assembly and the inner cylinder disc coarse limit assembly, the inner cylinder tooling disc and the outer cylinder tooling disc can achieve preliminary positioning during the transportation process on the inner cylinder disc conveying mechanism and the outer cylinder disc conveying mechanism, laying the foundation for accurate positioning during the pressing process. The workbench assembly composed of the workbench, the lower guide hole plate and the spacing guide plate can fully guide the fireworks inner cylinder monomer during the downward pressing process, reducing the risk of deviation; the outer cylinder tooling disc is lifted into place evenly and stably by the airbag lifting and supporting plate. The setting of the guide plate plays the role of fixing the guide column on the one hand, and plays the role of guiding and supporting the longer punch on the other hand, avoiding the punch from deflecting and scratching the guide hole or the clamping hole. By setting the side guard head on the outside of the side of the regular hexagon, the fireworks inner cylinder monomer that is moving upward can be blocked without interfering with the punch. By driving the limit rod up and down through the limit action cylinder, the inner cylinder tooling plate and the workbench assembly are first accurately positioned before the firework inner cylinder monomer is pressed down, ensuring that the punch can accurately enter the clamping hole.

[0024] The effect type combined fireworks production process of the present invention adopts the wax dripping method for sealing, which can be quickly dried and solidified compared with the yellow mud sealing, and does not need to be air-dried. Moreover, the sealing block sealed by paraffin wax can be easily dispersed by impact in the air, and will not fall and injure people or objects due to the hard block. The assembly machine station adopts the whole tray pressing method, which greatly improves the working efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] In a specific embodiment of the present invention, Figures 1 to 4 As shown, the effect type combined fireworks production line of the present invention comprises:

[0046] The inner tube conveyor belt group 1 includes a plurality of conveyor belt units, and the inner tube conveyor belt group 1 is a reciprocating circulation type. The inner tube tray loading machine 3 is arranged between the head and tail ends of the inner tube conveyor belt group 1, and a plurality of inner tube tool trays 100 for loading fireworks inner tubes are circulated and conveyed on the inner tube conveyor belt group 1. The inner tube tray loading machine 3 fills the empty inner tube tool tray 100 at the tail end of the inner tube conveyor belt group 1 with the fireworks inner tubes and feeds them to the head end of the inner tube conveyor belt group 1. The inner tube conveyor belt group 1 transports the inner tube tool tray 100 and the fireworks inner tubes through the bright bead adding machine 4, the charging machine 5, the first filling machine 6 and the sealing machine 7 in sequence. The charging machine 5 pours the opening medicine into the fireworks inner tube.

[0047] The outer cylinder conveyor belt group 2 includes a plurality of conveyor belt monomers, and the outer cylinder conveyor belt group 2 is a reciprocating circulation type. The outer cylinder loading machine 9 is arranged between the head and tail ends of the outer cylinder conveyor belt group 2, and a plurality of outer cylinder tooling discs 200 for loading and clamping the combined fireworks tube 23 are circulated and conveyed on the outer cylinder conveyor belt group 2. The outer cylinder loading machine 9 loads the empty outer cylinder tooling disc 200 at the tail end of the outer cylinder conveyor belt group 2 with the combined fireworks tube 23 and then feeds it to the head end of the outer cylinder conveyor belt group 2. The outer cylinder conveyor belt group 2 transports the outer cylinder tooling disc 200 through the propellant machine 10, the lower paper sheet machine 11, the assembly machine 8, the upper paper sheet machine 12 and the unloading station 13 in sequence. Among them, in the working room of the lower paper sheet machine 11 and the upper paper sheet machine 12, the yellow board paper roll is placed on the paper roll rack. The paper sheet machine automatically pressurizes the oil pressure device to ensure the power of the oil pressure component and punches the yellow board paper into a round paper sheet. The lower paper piece machine 11 automatically presses the round paper piece into the outer tube of the combined firework tube 23 to fix the propellant. The upper paper piece machine 12 automatically presses the round paper piece into the outer tube of the combined firework tube 23 to fix the inner tube of the firework.

[0048] The inner tube conveyor belt group 1 and the outer tube conveyor belt group 2 overlap in the upper and lower spaces at the position of the assembling machine 8 , and the assembling machine 8 loads the firework inner tube into the combined firework tube 23 .

[0049] By providing an inner cylinder tooling tray 100 and an outer cylinder tooling tray 200 to assist in conveying the firework inner cylinder and the combined firework cylinder 23 respectively, accurate positioning at each workstation is facilitated to ensure the accuracy of processes such as medicine filling and stuffing, and accurate alignment of the two monomers can be ensured at the assembly machine workstation 8 for smooth assembly; by combining the inner cylinder conveyor belt group 1 and the outer cylinder conveyor belt group 2 at the assembly machine workstation 8, the process of semi-finished inner cylinders entering and exiting the transit warehouse is avoided, the degree of automation is high, and both production efficiency and safety factor are improved.

[0050] In a specific embodiment of the present invention, Figure 1 As shown, the effect type combined fireworks production line of the present invention further includes a bead vibrating machine 24, which is arranged at the rear side of the charge loading machine 5 and before the filling device, and the bead vibrating machine 24 vibrates and tamps the bright beads and the packing powder loaded into the fireworks inner tube to make them uniform. The bright bead adding machine 4 automatically completes the filling of the bright beads into the fireworks inner tube through equipment vibration and mold quantitative filling, and the packing powder is filled above the bright beads. Through the action of the bead vibrating machine 24, the bright beads and the packing powder are mixed uniformly.

[0051] Specifically, if Figure 1As shown, independent explosion-proof rooms 16 are respectively provided around the bright bead adding machine 4, the charge loading machine 5, the charge launching machine 10 and the bead vibrating machine 24. A safety interlock device is installed at the entrance of the explosion-proof room 16. Once the operator opens the door, the equipment stops filling the medicine, thus avoiding the situation where people enter the equipment by mistake during operation. The unloading station 13 is separated from other parts of the outer cylinder conveyor belt group 2 by an explosion-proof wall 22. When the unloading station 13 is manually unloaded by workers, the explosion-proof wall 22 can effectively protect the workers.

[0052] Specifically, if Figure 1 As shown, a control room and an air pump room are also provided outside the return line of the inner tube conveyor belt group 1. The control room is provided with a general control console and video monitoring equipment for monitoring each explosion-proof room 16. The general control console can remotely control each device. The air pump room supplies clean compressed air to the pneumatic components on the inner tube conveyor belt group 1 and the outer tube conveyor belt group 2, as well as the pneumatic components on each device.

[0053] Specifically, if Figure 1 As shown, the effect type combined fireworks production line of the present invention further includes a bright bead storage room 25 and a propellant storage room 26, and the bright bead storage room 25 and the propellant storage room 26 are respectively set at a safe distance from the bright bead adding machine 4 and the propellant machine 10. The bright bead storage room 25 and the propellant storage room 26 respectively transport materials to the bright bead adding machine 4 and the propellant machine 10 through closed spiral conveying equipment. The bright bead storage room 25 and the propellant storage room 26 are both enclosed and protected by explosion-proof walls.

[0054] Specifically, if Figure 1 As shown, the feed port of the charging machine 5 is connected to a mixing barrel, and the oxidant, reducing agent and sulfur are fed to the mixing barrel through a screw conveyor respectively. The materials are mixed as they are fed, and there is no need for large-scale mixing and stirring. The raw materials of the oxidant and reducing agent are separately arranged in the raw material room on the opposite side of the charging machine 5. In the oxidant raw material room, the oxidant is poured into the oxidant hopper and transported to the mixing barrel through a screw conveyor. In the reducing agent raw material room, the reducing agent is poured into the reducing agent hopper and transported to the mixing barrel through a screw conveyor. The operator pours sulfur into the sulfur hopper and transports it to the mixing barrel through a screw conveyor. In a specific embodiment, potassium perchlorate is used as the oxidant, and aluminum-magnesium alloy powder and / or silver powder is used as the reducing agent. The mixing barrel uses the free fall of chemical raw materials and the vibration of the machine to automatically complete the mixing of chemical raw materials. After the chemical raw materials are mixed, they become unpacked medicines, also known as effect medicines. The powder mixing cylinder automatically charges the firework inner cylinder downward through a plurality of delivery tubes. The charging process is quantitatively controlled by a mold, and the charging is performed in the form of inserting the delivery tube opening into the hole in the firework inner cylinder.

[0055] By setting the vibrating bead machine 24 at the rear side of the charge machine 5, the unpacking medicine and the bright beads can be mixed evenly, improving the fireworks display effect. By setting up the explosion-proof room 16, the dangerous workstations are isolated, and the safety performance of the production line is improved. By setting up separate raw material rooms for the raw materials of the oxidant and the reductant, and using a screw conveyor for transportation, the raw materials are mixed as they are fed, avoiding the dangers caused by large-scale mixed medicines, and the isolated and separate storage is safe. The delivery pipe is used to probe into the inner tube of the fireworks to charge the powder, which reduces dust.

[0056] In a specific embodiment of the present invention, Figure 1 As shown, the second filler 14 and the dust extractor 15 are also included. The second filler 14 and the dust extractor 15 are sequentially arranged behind the first filler 6. The first filler 6 is filled with sawdust, and the second filler 14 is filled with perlite powder. The material filling nozzles of the first filler 6 and the second filler 14 can be inserted into the middle hole of the firework inner tube. Moreover, the first filler 6 and the second filler 14 also compact the filled filler. The exhaust hood of the dust extractor 15 can clean the debris on the top surface of the firework inner tube.

[0057] Two filling machines are provided, and different filling materials can be filled in respectively and simultaneously, so as to obtain better filling and sealing effects; through the provision of the dust extractor 15, the sundries on the top surface of the firework inner tube can be cleaned in time, so as to facilitate the subsequent sealing and assembly.

[0058] In a specific embodiment of the present invention, Figure 1 As shown, the effect type combined fireworks production line of the present invention further includes a packaging conveyor belt 19, the feeding end of the packaging conveyor belt 19 is connected to the unloading station 13, and a mounting machine 20 and a labeling machine 21 are sequentially arranged on the packaging conveyor belt 19. The mounting machine 20 can wrap the upper and lower sealing papers and the surrounding wallpaper on the outer wall of the combined fireworks tube 23 that has been completed internally, and the labeling machine 21 can print the production date and identification information.

[0059] By adding the packaging conveyor belt 19, the mounting machine 20 and the labeling machine 21, the combined firework tube 23 completed with the internal operation can be directly processed into a finished product without further transportation, and can be directly stored in a finished product warehouse or shipped.

[0060] In a specific embodiment of the present invention, Figures 2 to 8As shown, the inner cylinder tooling plate 100 includes an inner cylinder mounting plate 110, a mounting cover plate 120 and a rubber plate 130. The inner cylinder mounting plate 110 is provided with a plurality of mounting holes 121 for mounting the firework inner cylinder monomer, and the mounting cover plate 120 connected by screws presses the rubber plate 130 on the top surface of the inner cylinder mounting plate 110, that is, the mounting cover plate 120, the rubber plate 130 and the inner cylinder mounting plate 110 are stacked together. The mounting cover plate 120 is provided with through holes at the top of the mounting holes 121 of the rubber plate 130, and the rubber plate 130 is provided with a retaining edge head 131 at the top of the mounting holes 121, and the retaining edge head 131 prevents the firework inner cylinder monomer installed in the mounting holes 121 from slipping out upward.

[0061] The top surface of the outer cylinder tooling tray 200 is provided with a plurality of outer cylinder assembly mounting pits 210 arranged regularly, and the combined firework tubes 23 are vertically installed in the outer cylinder assembly mounting pits 210. The bottom surface of the outer cylinder assembly mounting pits 210 is provided with bottom through holes 220 for exhausting during the process of pressing the firework inner cylinder monomers, and the bottom of the combined firework tubes 23 is also provided with exhaust holes. All the outer cylinder monomers of the combined firework tubes 23 on the outer cylinder tooling tray 200 can correspond to the mounting holes 121 of the inner cylinder mounting plate 110 one by one and are coaxially arranged and received directly below the mounting holes 121.

[0062] In a specific embodiment, if Figures 2 to 10 As shown, the combination firework tube 23 is a combination firework with 19 shots, and the top surface of the outer tube tooling plate 200 is provided with 6 groups of outer tube combination mounting pits 210 , that is to say, the number of the outer tube monomers is 19×6=114, which is consistent with the number of the mounting holes 121 .

[0063] By arranging a rubber plate 130 between the inner tube mounting clamping plate 110 and the mounting cover plate 120, and arranging a retaining edge head 131 at the top of the mounting hole 121 of the rubber plate 130, the firework inner tube monomer can be prevented from escaping upward from the mounting hole 121, thereby avoiding the occurrence of empty shots. By arranging a plurality of regularly arranged outer tube assembly mounting pits 210 on the top surface of the outer tube tooling plate 200, each outer tube assembly mounting pit 210 is clamped with a combined firework tube 23, and the firework inner tube monomer can be pressed while completing a plurality of combined firework tubes 23 at the same time, thereby improving production efficiency.

[0064] In a specific embodiment of the present invention, Figures 2 to 6As shown, the assembly machine 8 includes a frame 801, an outer cylinder plate conveying mechanism 802, an inner cylinder plate conveying mechanism 803, a punching mechanism, a centering mechanism, a lifting assembly 810 and a workbench assembly. The outer cylinder plate conveying mechanism 802 and the inner cylinder plate conveying mechanism 803 are both horizontally arranged on the frame 801 and the two are vertically arranged. The outer cylinder plate conveying mechanism 802 and the inner cylinder plate conveying mechanism 803 respectively complete the work of conveying the outer cylinder tooling plate 200 and the inner cylinder tooling plate 100 to the position. The workbench assembly is horizontally arranged on the frame 801 and is located between the outer cylinder plate conveying mechanism 802 and the inner cylinder plate conveying mechanism 803. The workbench assembly is used to carry the inner cylinder tooling plate 100 that needs to be pressed. The punching mechanism and the centering mechanism are arranged at the top of the frame 801. The centering mechanism aligns the inner cylinder tooling tray 100 delivered by the inner cylinder tray conveying mechanism 803 on the workbench assembly. The working end of the punching mechanism can be pushed downward into the clamping hole 121 of the inner cylinder tooling tray 100 and push the fireworks inner cylinder monomer into the combined fireworks tube 23 on the outer cylinder tooling tray 200 delivered by the outer cylinder tray conveying mechanism 802. The lifting assembly 810 is arranged at the bottom of the frame 801 and is located below the outer cylinder tray conveying mechanism 802. The lifting assembly 810 can lift the outer cylinder tooling tray 200 upward to receive it.

[0065] Specifically, if Figure 3 and Fig.12 As shown, one end of the outer cylinder disc conveying mechanism 802 is provided with an outer cylinder disc rough limit assembly 8021, which includes a positioning tongue 8022, a tongue action cylinder 8023, an articulated seat 8024 and a swing connection plate 8025.

[0066] Specifically, if Figure 2 , Figure 3 and Figure 6 As shown, one end of the inner cylinder disc conveying mechanism 803 is provided with an inner cylinder disc rough limiting assembly 8031 ​​for limiting the inner cylinder tooling disc 100, and the inner cylinder disc rough limiting assembly 8031 ​​includes a limiting block and a limiting mounting plate, the limiting block is installed in the middle position of the limiting mounting plate and limits the edge of the inner cylinder tooling disc 100. The limiting mounting plate is installed in the guide mounting grooves of the profiles of the two arms of the inner cylinder disc conveying mechanism 803 through waist-shaped holes and T-shaped head bolts.

[0067] By stacking the inner cylinder tray conveying mechanism 803 and the outer cylinder tray conveying mechanism 802 vertically and vertically, the inner cylinder tooling tray 100 and the outer cylinder tooling tray 200 are overlapped and aligned at the assembly machine 8 station, thereby ensuring the press-fitting of the fireworks inner cylinder monomer. By setting the lifting component 810, it can be ensured that the outer cylinder tooling tray 200 and the combined fireworks tube 23 are lifted upward to the bottom of the workbench assembly before pressing in, so as to be seamlessly received, thereby preventing the fireworks inner cylinder monomer from being pressed out of alignment and unable to accurately enter the outer cylinder monomer. By setting the outer cylinder tray rough limit component 8021 and the inner cylinder tray rough limit component 8031, the inner cylinder tooling tray 100 and the outer cylinder tooling tray 200 are initially positioned during transportation on the inner cylinder tray conveying mechanism 803 and the outer cylinder tray conveying mechanism 802, laying the foundation for accurate positioning during the pressing process.

[0068] Specifically, if Figures 4 to 6 As shown, the workbench assembly includes a workbench 811, a lower guide hole plate 812 and a spacing guide plate 813. The workbench 811, the lower guide hole plate 812 and the spacing guide plate 813 are vertically provided with guide holes corresponding to the mounting holes 121. During the pressing process, the fireworks inner tube monomer is transported downward from the guide holes. The edge of the horizontally arranged workbench 811 is fixedly connected to the frame 801. The spacing guide plate 813 is fixedly connected to the workbench 811 and its height is consistent with the two side walls of the inner tube disc conveying mechanism 803. The lower guide hole plate 812 is fixedly connected to the bottom surface of the workbench 811. The lower guide hole plate 812 is provided with a positioning groove corresponding to the outer tube assembly mounting pit 210. The positioning groove limits the top of the combined fireworks tube 23 lifted by the lifting assembly 810. The edge of the positioning groove is provided with a guiding bevel.

[0069] Specifically, if Figures 4 to 6 As shown, the lifting assembly 810 includes an airbag, a lower limiting rod 8101, an upper limiting rod 8102 and a top supporting plate 8103. The airbag is fixedly connected to the bottom of the frame 801 through a bottom supporting plate, and the top of the airbag is fixedly connected to the horizontally arranged top supporting plate 8103. The top supporting plate 8103 is connected to the bottom supporting plate of the airbag through a vertical guide rod, and the top supporting plate 8103 can lift the outer cylinder tooling plate 200 upward. The lower limiting rod 8101 and the upper limiting rod 8102 are vertically arranged on the bottom surface of the top supporting plate 8103 to limit the lifting height and the descending position of the top supporting plate 8103.

[0070] The workbench assembly composed of a workbench 811, a lower guide hole plate 812 and a spacing guide plate 813 can fully guide the firework inner tube monomer during the downward pressing process, reducing the risk of deviation; the outer tube tooling plate 200 is lifted into place evenly and stably by the air bag lifting and supporting plate 8103.

[0071] In a specific embodiment of the present invention, Figures 2 to 6 As shown, the punching mechanism includes a main action cylinder 804, a punch mounting plate group 805, a punch 806 and a guide plate 807. The top of the frame 801 is horizontally connected to a top plate 8012 through four guide columns 8011, the main action cylinder 804 is centrally mounted on the top plate 8012 with its head facing downward, and the end of the piston rod of the main action cylinder 804 extending downward is fixedly connected to the punch mounting plate group 805, and the punch mounting plate group 805 is horizontally arranged and vertically guided and slidable on the guide column 8011. The punch mounting plate group 805 includes a mounting base plate 8051, a mounting cover plate 8052 and a guide sleeve 8053 which are stacked together by bolts. The mounting cover plate 8052 is provided with a hole for mounting the punch 806, and the root step of the punch 806 is pressed between the mounting base plate 8051 and the mounting cover plate 8052; the mounting cover plate 8052 is fixedly connected to the vertically arranged guide sleeve 8053, and the guide sleeve 8053 is guided to slide on the guide column 8011. A plurality of punches 806 are regularly arranged at the bottom of the punch mounting plate group 805, and the punches 806 are arranged one by one corresponding to the mounting holes 121. The guide plate 807 is horizontally fixedly connected to the bottom of the guide column 8011, and the guide plate 807 is provided with a guide hole for the punch 806 to slide.

[0072] Specifically, if Figure 3 and Fig.11 The cross-sectional outer contour of the punch 806 is a regular hexagon, and the diameter of the clamping hole 121 is greater than the diagonal length of the regular hexagon. There are six side guards 131 and they are respectively arranged outside the sides of the regular hexagon, and the side guards 131 extend into the clamping hole 121.

[0073] The guide plate 807 can fix the guide column 8011 and guide the relatively long punch 806, thereby preventing the punch 806 from deviating and scratching the guide hole or the mounting hole 121. The side guard 131 can be arranged outside the side of the regular hexagon to prevent the punch 806 from interfering with the side guard 131 and to block the upwardly moving firework inner tube.

[0074] In a specific embodiment of the present invention, Figure 2 , Figure 3 and Figure 6 As shown, the two sets of centering mechanisms are arranged on opposite sides of the stamping mechanism, and the centering mechanism includes a limit cylinder 808 and a limit rod 809. The limit cylinder 808 is installed head-down at both ends of the top plate 8012, and the piston rod extending downward from the limit cylinder 808 is fixedly connected to the limit rod 809. The limit rod 809 is vertically guided to pass through the guide plate 807 and the bottom end can be connected to the positioning inner cylinder tooling plate 100 and the work table assembly.

[0075] Specifically, positioning guide holes are provided at both ends of the inner cylinder tooling disk 100, that is, a positioning guide hole 122 is provided on the mounting cover plate 120, and a coaxial positioning guide hole 2 is provided on the inner cylinder mounting clamping plate 110. A pointed tip is provided at the bottom end of the limiting rod 809, and the pointed tip passes through the positioning guide hole 122 and the positioning guide hole 2 and then enters the guide hole of the spacing guide plate 813.

[0076] Specifically, a limiting sleeve 140 is installed in the positioning guide hole 122 , and the limiting sleeve 140 limits the limiting rod 809 .

[0077] By driving the limiting rod 809 up and down through the limiting cylinder 808, the inner cylinder tooling plate 100 and the workbench assembly are first accurately positioned before the firework inner cylinder unit is pressed down, ensuring that the punch 806 can accurately enter the clamping hole 121.

[0078] The working process of the assembly machine 8 in the present invention is as follows: the inner cylinder conveyor belt group 1 conveys the inner cylinder tooling disc 100 loaded with the fireworks inner cylinder monomer to the inner cylinder disc conveying mechanism 803. Multiple inner cylinder tooling discs 100 enter the inner cylinder disc conveying mechanism 803 under the push of the end push cylinder and are limited by the inner cylinder disc rough limit assembly 8031 ​​at one end of the outlet. At this time, an inner cylinder tooling disc 100 enters directly above the workbench assembly. The outer cylinder conveyor belt group 2 conveys the outer cylinder tooling disc 200 from the lower paper machine 11 station to the outer cylinder disc conveying mechanism 802. The tongue action cylinder 8023 is pushed out, and the positioning tongue 8022 is extended to initially limit the edge of the outer cylinder tooling disc 200. The limiting action cylinder 808 is pushed downward, and the limiting rod 809 passes through the guide sleeve and the positioning guide hole 122 on the guide plate 807, and the positioning guide hole 2 is placed in the guide hole of the spacing guide plate 813 to complete precise positioning. The airbag of the lifting assembly 810 is inflated and lifted to a high position. The lifting plate 8103 lifts the outer tube tooling plate 200 upward, and the top of the combined firework tube 23 enters the positioning groove of the lower guide hole plate 812, ensuring that the outer tube monomer is accurately received directly below the mounting hole 121 and its corresponding guide hole. The main action cylinder 804 begins to push downward, and the punch mounting plate group 805 slides downward along the guide column 8011. The punch 806 accurately enters the mounting hole 121 under the guidance and support of the guide plate 807. During this process, the punch 806 with a regular hexagonal cross-section does not interfere with the retaining edge head 131. The punch 806 continues to move downward, pushing the firework inner tube monomer in the mounting hole 121 downward, and successively passes through the bottom of the mounting hole 121, the spacing guide plate 813, the workbench plate 811 and the guide hole of the lower guide hole plate 812 into the outer tube monomer. The main action cylinder 804 retracts and drives the punch 806 to return; the airbag of the lifting assembly 810 shrinks, and the top support plate 8103 returns to the low position with the outer cylinder tooling disc 200, and the tongue action cylinder 8023 retracts the positioning tongue 8022, and under the action of the outer cylinder disc conveying mechanism 802, it is conveyed to the rear end and introduced into the next outer cylinder tooling disc 200 that needs to be pressed. At the same time, the limit action cylinder 808 retracts and drives the limit rod 809, and the inner cylinder tooling disc 100 enters the return stage under the push of the end push cylinder and introduces a new inner cylinder tooling disc 100 that needs to be pressed, and the cycle is repeated to complete the work of pressing the fireworks inner cylinder monomer into the combined fireworks tube 23.

[0079] In summary, the effect-type combined fireworks production line of the present invention, by setting the inner tube tooling plate 100 and the outer tube tooling plate 200, respectively assists in conveying the fireworks inner tube and the combined fireworks tube 23, which is convenient for accurate positioning at each station, ensuring the accuracy of the filling and filling processes, and can ensure that each monomer of the two is accurately aligned at the assembly machine 8 station, and smoothly assembled; by combining the inner tube conveyor belt group 1 and the outer tube conveyor belt group 2 at the assembly machine 8 station, the semi-finished inner tube is avoided from entering and exiting the transit warehouse, the degree of automation is high, and the production efficiency and safety factor are improved. In addition, by setting the vibrating bead machine 24 on the rear side of the charge machine 5, the unpacking medicine and the bright beads can be mixed evenly, which improves the fireworks display effect. By setting up the explosion-proof room 16, the dangerous stations are isolated, and the safety performance of the production line is improved. By setting up separate raw material rooms for the raw materials of the oxidant and the reductant, and adopting the screw conveyor transportation method, the raw materials are mixed as they are fed, the dangers caused by large-scale mixed medicine are avoided, and the isolated and separate storage is safe. The conveying pipe is used to probe into the inner tube of the fireworks to charge the powder, thereby reducing dust. Two filling machines are provided, and different filling materials can be filled in respectively and simultaneously, so as to obtain better filling and sealing effects; by providing the dust extractor 15, the debris on the top surface of the inner tube of the fireworks can be cleaned in time, which is convenient for subsequent sealing and assembly. By adding a packaging conveyor belt 19, a mounting machine 20 and a labeling machine 21, the combined fireworks tube 23 after the internal operation is completed can be directly processed into a finished product without further transportation, and can be directly stored in a finished product warehouse or shipped. By providing a rubber plate 130 between the inner tube mounting clamp plate 110 and the mounting cover plate 120, and providing a retaining head 131 at the top of the mounting hole 121 of the rubber plate 130, the inner tube monomer of the fireworks can be prevented from escaping upward from the mounting hole 121, thereby avoiding the occurrence of empty guns. By setting a plurality of regularly arranged outer cylinder assembly clamping pits 210 on the top surface of the outer cylinder tooling tray 200, each outer cylinder assembly clamping pit 210 is clamped with a combined firework tube 23, and multiple combined firework tubes 23 can be completed at the same time while the firework inner cylinder monomer is pressed, thereby improving production efficiency. By stacking the inner cylinder tray conveying mechanism 803 and the outer cylinder tray conveying mechanism 802 vertically and crosswise, the inner cylinder tooling tray 100 and the outer cylinder tooling tray 200 are overlapped and aligned at the assembly machine 8 station, thereby ensuring the press-fitting of the firework inner cylinder monomer. By setting the lifting assembly 810, it can be ensured that the outer cylinder tooling tray 200 and the combined firework tube 23 are lifted upward to the bottom of the workbench assembly before pressing in, so as to be connected without gaps, thereby preventing the firework inner cylinder monomer from being pressed off and unable to accurately enter the outer cylinder monomer. By setting the outer cylinder disc coarse limit assembly 8021 and the inner cylinder disc coarse limit assembly 8031, the inner cylinder tooling disc 100 and the outer cylinder tooling disc 200 can be initially positioned during transportation on the inner cylinder disc conveying mechanism 803 and the outer cylinder disc conveying mechanism 802, laying the foundation for accurate positioning during the pressing process.The workbench assembly composed of the workbench 811, the lower guide hole plate 812 and the spacing guide plate 813 can fully close the guide during the downward pressing of the fireworks inner cylinder monomer, reducing the risk of deviation; the outer cylinder tooling plate 200 is lifted into place evenly and stably by the air bag lifting and supporting plate 8103. The setting of the guide plate 807 plays the role of fixing the guide column 8011 on the one hand, and guiding and supporting the longer punch 806 on the other hand, so as to avoid the punch 806 from deflecting and scratching the guide hole or the clamping hole 121. By setting the side guard 131 outside the side of the regular hexagon, it is possible to block the upwardly moving fireworks inner cylinder monomer in the case of interference with the punch 806. By the limit action cylinder 808 driving the limit rod 809 up and down, the inner cylinder tooling plate 100 and the workbench assembly are first accurately positioned before the fireworks inner cylinder monomer is pressed down, ensuring that the punch 806 can accurately enter the clamping hole 121.

[0081] S1. Inner tube assembly: The inner tube conveyor belt group 1 carries the inner tube tooling plate 100 and the firework inner tube through the bright bead adding machine 4, the charge machine 5, the first filler 6 and the sealing machine 7 in sequence, and completes the bright bead filling, unpacking and filling, vibrating and tamping, filling and pressing of the filler and sealing operations respectively.

[0082] It should be noted that the fireworks inner tube loaded into the head end of the inner tube conveyor belt group 1 is a single tube that has been primed and wired in other workshops.

[0083] Specifically, the filler is perlite powder, and the sealing operation uses liquid industrial paraffin to drip onto the filler for solidification and sealing.

[0084] S2, outer tube assembly: the outer tube conveyor belt group 2 takes the outer tube tooling tray 200 and the combined firework tube 23 to the propellant machine 10 for propellant filling, and then goes to the paper sheet machine 11 to install the lower paper sheet. Then, the firework inner tube sealed in the above step S1 is assembled into the combined firework tube 23 at the assembly machine 8 station, and the whole tray press-fit method is adopted to complete the installation of the whole tray of the firework inner tube at one time. Then, it enters the paper sheet machine 12 to install the upper paper sheet and then enters the unloading station 13.

[0085] It should be noted that the combined firework tube 23 loaded into the outer tube tooling tray 200 at the head end of the outer tube conveyor belt group 2 is a whole tube assembly that has been primed and wired in other workshops.

[0086] By using wax dripping method for sealing, compared with yellow mud sealing, it can dry and solidify quickly without airing, and the sealing block sealed by paraffin is easy to be scattered by impact in the air, and will not fall and injure people or objects due to hard blocks. The 8th station of the assembly machine adopts the whole tray pressing method, which greatly improves the working efficiency.

[0087] In a specific embodiment of the production process of effect-type combined fireworks of the present invention, it also includes mounting and labeling stations, and a packaging conveyor belt 19 is added to the unloading station 13.
