Description

Technical Field

[0001] This invention relates to the field of fireworks production technology, and specifically to a fireworks production line. Background Technology

[0002] In the fireworks production process, with the increasing standardization of production safety, it is best to isolate different production steps to localize safety risks and prevent accidents from escalating. Prior art (publication number CN 223077547U) proposes using isolation walls between different pieces of equipment to effectively prevent the spread of accidents. However, in this technology, the inner tube filling equipment is directly connected to the production line, and manual feeding is required. This means that the personnel feeding the inner tube cannot be isolated from the production line, making it easy for accidents on the production line to spread. Therefore, we provide a fireworks production line. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a fireworks production line.

[0004] The fireworks production line of the present invention includes: The fireworks assembly line includes, in sequence, a primer filling device, a primer detection device, a first fireworks paper filling device, a paper detection device, and a second fireworks paper filling device, all connected by a connecting conveyor belt. The inner cylinder filling line includes a ring conveyor line, an inner cylinder filling device, and a feeding mechanism. The ring conveyor line is provided with multiple filling molds, and the ring conveyor line is provided with a loading station for installing the inner cylinder filling device and a feeding station for installing the feeding mechanism. The unloading station is located above the connecting conveyor belt between the paper detection equipment and the second fireworks paper filling equipment, and the connecting conveyor belt has a filling station directly opposite the unloading station. The feeding mechanism is used to load the inner cylinder from the filling mold into the firework blasting station.

[0005] The circular conveyor line is composed of multiple conveyor belts spliced ​​together, and a transfer mechanism for transferring the filling mold on different conveyor belts is installed at the corners of the conveyor belts.

[0006] The unloading station is an opening between the beginning and end of the annular conveyor line. A transition mechanism is provided at the opening. The transition mechanism is used to move the filling mold carrying the inner cylinder from the end of the annular conveyor line to the unloading station and the beginning of the annular conveyor line. The conveyor belt a at the tail end of the circular conveyor line and the conveyor belt b at the head end of the circular conveyor line are arranged perpendicularly or along the same conveyor axis on the same horizontal plane.

[0007] The filling mold includes a bottom plate and a top plate; The top plate is provided with a first set of filling holes corresponding to the fireworks. The base plate is movably installed at the bottom of the top plate through a connecting mechanism, and a second filling hole group corresponding to the firework blasting is provided on the base plate. When the base plate and the top plate overlap, the first filling hole group and the second filling hole group are staggered, and the first filling hole group is located above the spacing of the second filling hole group. The connecting mechanism can move the base plate below the top plate so that the second filling hole group is aligned with the first filling hole group.

[0008] The transition mechanism includes a linear drive mechanism parallel to conveyor belt a and conveyor belt b. Two automatic telescopic rods are installed on the linear drive mechanism, and a transition station is formed between the automatic telescopic rods. The initial transition station is located at the tail end of conveyor belt a.

[0009] It also includes a positioning and opening assembly, which includes a support plate, a limiting cylinder, a limiting block, a limiting component, and an opening push rod parallel to the automatic telescopic rod. The opening push rod is provided with an opening push block facing the filling plate in the unloading station. The bearing plate is installed horizontally with the conveying surface of the annular conveyor line in the unloading station. The limiting cylinder and the limiting block are both installed on the bearing plate. The limiting component is installed on the linear drive mechanism and moves with the limit telescopic rod, which is parallel to the automatic telescopic rod. The support plate is provided with a discharge hole that is aligned with the fireworks pellets and the first filling hole group in the filling station; The limiting component and the opening push block correspond to the top plate and bottom plate of the filling mold being on different horizontal planes.

[0010] The feeding mechanism includes a feeding telescopic rod that is mounted on the frame above the feeding station. The feeding telescopic rod is vertically arranged and has a feeding rod group at its bottom that is aligned with the first filling hole group on the filling mold located at the feeding station.

[0011] It also includes an isolation wall that can independently separate the primer filling equipment, primer detection equipment, first firework paper filling equipment, paper detection equipment, second firework paper filling equipment, and inner cylinder filling equipment and feeding mechanism in the inner cylinder filling line. The isolation wall has through holes for connecting the conveyor belt or conveyor belt. The through holes for connecting the conveyor belt are designed as firework production transfer chambers through which the firework pellets can pass.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention effectively improves production safety at the loading station by separating the inner cylinder filling equipment and the unloading mechanism in the inner cylinder filling line with an isolation wall. Furthermore, because the through hole in the isolation wall used to connect the conveyor belt is designed as a fireworks production transfer chamber through which the fireworks pellets can pass, each equipment area of ​​the fireworks pellet moving production line can be isolated, thereby further increasing the safety of the equipment.

[0017] Please see Figures 1-10 The fireworks production line of the present invention includes: The fireworks assembly line A includes, in sequence, a primer filling device 1, a primer detection device 2, a first fireworks paper filling device 3, a paper detection device 4, and a second fireworks paper filling device 5, all connected by a connecting conveyor belt 6. The inner cylinder filling line B includes a ring conveyor line 7, an inner cylinder filling device 8, and a feeding mechanism 9. The ring conveyor line 7 is equipped with multiple filling molds 10, and the ring conveyor line 7 is equipped with a feeding station a for installing the inner cylinder filling device 8 and a feeding station b for installing the feeding mechanism 9. The unloading station b is located above the connecting conveyor belt 6 between the paper detection equipment 4 and the second fireworks paper filling equipment 5. The connecting conveyor belt 6 is directly opposite the unloading station b and has a filling station c. The feeding mechanism 9 is used to load the inner cylinder in the filling mold 10 into the firework blasting at the filling station c.

[0018] The circular conveyor line 7 is composed of multiple conveyor belts spliced ​​together, and a transfer mechanism 12 for transferring the filling mold 10 on different conveyor belts is installed at the corners of the conveyor belts. Specifically, the two conveyor belts are either parallel or perpendicular to each other. The transfer mechanism 12 on the two perpendicularly perpendicular conveyor belts is a linear drive mechanism for the downstream conveyor belt, such as a linear cylinder.

[0019] The unloading station b is an opening between the head and tail of the circular conveyor line 7. A transition mechanism 11 is provided at the opening. The transition mechanism 11 is used to transfer the filling mold 10 carrying the inner cylinder from the tail end of the circular conveyor line 7 to the unloading station b and the head end of the circular conveyor line 7. Specifically, the conveyor belt a701 at the tail end of the circular conveyor line 7 and the conveyor belt b702 at the head end of the circular conveyor line 7 are arranged vertically or along the same conveying axis on the same horizontal plane.

[0020] The filling mold 10 includes a base plate 1002 and a top plate 1001; The top plate 1001 is provided with a first loading hole group 1003 corresponding to the firework blasting shell; The base plate 1002 is movably installed at the bottom of the top plate 1001 via the connecting mechanism 1005, and the base plate 1002 is provided with a second filling hole group 1004 corresponding to the firework blast. When the base plate 1002 and the top plate 1001 overlap, the first filling hole group 1003 and the second filling hole group 1004 are misaligned, and the first filling hole group 1003 is located above the spacing of the second filling hole group 1004. The connecting mechanism 1005 can carry the bottom plate 1002 to move below the top plate 1001 so that the second filling hole group 1004 is aligned with the first filling hole group 1003.

[0021] The transition mechanism 11 includes a linear drive mechanism 1101 parallel to the conveyor belt a701 and the conveyor belt b702. Two automatic telescopic rods 1102 are installed on the linear drive mechanism 1101, and a transition station 1103 is formed between the automatic telescopic rods 1102. The initial transition station 1103 is located at the tail end of the conveyor belt a701.

[0022] It also includes a positioning and opening assembly 13, which includes a support plate 1306, a limiting cylinder 1305, a limiting block 1301, a limiting member 1302, and an opening push rod 1303 parallel to the automatic telescopic rod 1102. The opening push rod 1303 is provided with an opening push block 1304 facing the filling plate 802 in the unloading station b. The bearing plate 1306 is installed horizontally with the conveying surface of the annular conveyor line 7 in the unloading station b. The limiting cylinder 1305 and the limiting block 1301 are both installed on the bearing plate 1306. The limiting member 1302 is installed on the linear drive mechanism 1101 through the limiting telescopic rod 1307 parallel to the automatic telescopic rod 1102 and moves accordingly. The support plate 1306 has a discharge hole that is aligned with the firework pellets and the first filling hole group 1003 in the filling station c; The limiting component 1302 and the opening push block 1304 correspond to the top plate 1001 and bottom plate 1002 of the filling mold 10, respectively, and are located on different horizontal planes.

[0023] The unloading mechanism 9 includes an unloading telescopic rod 91 mounted on the frame above the unloading station b. The unloading telescopic rod 91 is vertically arranged and has an unloading rod group 92 at its bottom that is aligned with the first filling hole group 1003 on the filling mold 10 located at the unloading station b.

[0024] It also includes a partition wall 14, which can independently separate the primer filling equipment 1, primer detection equipment 2, first firework paper filling equipment 3, paper detection equipment 4, second firework paper filling equipment 5, and inner cylinder filling equipment 8 and unloading mechanism 9 in inner cylinder filling line B. The partition wall 14 is provided with a through hole for connecting the conveyor belt 6 or for the conveyor belt to pass through. The through hole of the partition wall 14 for connecting the conveyor belt 6 is set as a firework production transfer chamber 15 through which the firework shavings can pass.

[0025] Working principle: The fireworks are manually placed on the connecting conveyor belt 6 at the initial section of the fireworks movement line A, so that the fireworks enter the primer filling device 1 to be filled with primer. After passing through the primer detection device 2, they enter the first fireworks paper filling device 3 to be filled with bottom paper. After passing through the paper detection device 4, they move to the filling station c via the connecting conveyor belt 6. When the fireworks are at the filling station c, the inner cylinder filling line B will fill the fireworks with the inner cylinder. Then, driven by the connecting conveyor belt 6, the fireworks move to the second fireworks paper filling device 5 to be filled with top paper, thus completing the production of the fireworks.

[0026] In the inner cylinder filling line B: S1. The circular conveyor line 7 carries the filling mold 10 through the inner cylinder filling equipment 8. Then, under the start of the inner cylinder filling equipment 8, the inner cylinder is filled into the filling mold 10. Then, under the drive of the circular conveyor line 7, the filling mold 10 carrying the inner cylinder moves to the end of the conveyor belt b702 and enters the transition station 1103. S2. At this time, the automatic telescopic rod 1102 in the transition station 1103 is in the extended state. Then, the linear drive mechanism 1101 carries the transition station 1103 formed by the two automatic telescopic rods 1102 to the bearing plate (1306) of the unloading station b. While the transition station 1103 moves, the filling mold 10 will also move synchronously. When the filling mold 10 is located on the unloading station b, it will be blocked by the extended limit cylinder 1305, thus effectively stopping at the corresponding point of the unloading station b. S3. Then, the opening push rod 1303 in the positioning opening assembly 13 is activated, causing the opening push block 1304 to push the bottom plate 1002 of the filling mold 10. Since the top plate 1001 is blocked by the limiting member 1302 on the other side, the bottom plate 1002 will be displaced relative to the top plate 1001 after being pushed by the opening push block 1304, thereby aligning the misaligned second filling hole group 1004 on the bottom plate 1002 with the first filling hole group 1003 and the unloading rod group 92 in the unloading mechanism 9. S4. The feeding telescopic rod 91 in the feeding mechanism 9 is activated, causing the feeding rod assembly 92 to be inserted into the filling mold 10, pushing the inner cylinder into the firework sphere in the filling station c; S5. After the material feeding mechanism 9 completes its reset, the push rod 1303 is activated to reset. After the bottom plate 1002 in the filling mold 10 loses its thrust, it will reset under the reset of the connecting mechanism 1005. Then the limit cylinder 1305 retracts to release the limit on the conveying end of the inner cylinder filling station c. S6. Then the linear drive mechanism 1101 in the transition mechanism 11 carries the transition station 1103 to the head end of the ring conveyor line 7, that is, on the conveyor belt b702. The filling mold 10 located on the conveyor belt b702 will move to the filling station c under the drive of the ring conveyor line 7, and then be filled into the inner cylinder by the inner cylinder filling device 8. S7. Then the automatic telescopic rod 1102 of the transition station 1103 retracts and is reset to the end of the conveyor belt a701 under the drive of the linear drive mechanism 1101. Then the automatic telescopic rod 1102 extends again and the new filling mold 10 is placed in the transition station 1103, so that the inner cylinder filling line B automatically and cyclically feeds the fireworks in the filling station c. The limiting telescopic rod 1307 can effectively change the initial position of the filling mold 10 in the transition station 1103 by moving the limiting member 1302.

[0027] The connecting mechanism 1005 includes a pin 10051, a limiting plate 10055, a nut 10052, and an elastic element 10053 spring. The top of the pin 10051 is provided with a thread that is compatible with the nut 10052. The top plate 1001 has a movable hole 10056 that matches the pin 10051, and the limiting plate 10055 covers the movable hole 10056. The bottom plate 1002 and the limiting plate 10055 both have assembly holes. The pin 10051 passes through the beginning of the assembly hole and the movable hole 10056 and is locked by the nut 10052. The inner wall of the movable hole 10056 is provided with a mounting groove 10054 for the installation of the elastic element 10053. The two ends of the elastic element 10053 abut against or insert into the inner wall of the pin 10051 and the mounting groove 10054, respectively. When the top plate 1001 is pressed against the bottom plate 1002, and the bottom plate 1002 is subjected to a thrust parallel to the elastic element 10053 spring, the bottom plate 1002 will cause the pin 10051 to squeeze the elastic element 10053 spring, thereby causing the bottom plate 1002 to complete the displacement. When the bottom plate 1002 loses the thrust, it will automatically reset under the action of the elastic element 10053 spring.

[0028] In this embodiment: Because the partition wall 14 separates the inner cylinder filling equipment 8 and the unloading mechanism 9 in the inner cylinder filling line B, the production safety of the loading station a is effectively improved. Furthermore, because the through hole of the partition wall 14 used to connect the conveyor belt 6 is set as the fireworks production transfer chamber 15 through which the fireworks can pass, each equipment area of ​​the fireworks moving production line can be isolated, thereby further increasing the safety of the equipment. The inner cylinder filling device 8 in this embodiment can be "the one with the publication number: CN 219141653 U, named a fireworks and firecracker filling production line"; Alternatively, please see Figures 11-13The inner cylinder filling equipment 8 specifically includes a feeding assembly 801 and a feeding mechanism 808. The specific structure of the feeding assembly 801 has been described in detail in CN 219141653 U. A filling plate 802 is installed at the discharge port of the feeding assembly 801. The filling plate 802 has a material storage hole 803. The filling plate 802 is slidably connected to the filling frame 804. The filling frame 804 and the feeding assembly 801 are installed on the same filling frame 805, and the filling frame 804 and the filling frame 805 are rotatably connected by a rotating shaft. A positioning drive cylinder 806 is installed on the filling frame 804, and a rotation drive cylinder 807 for driving the filling frame 804 to rotate is installed on the filling frame 805. The feeding mechanism 808 includes a feeding telescopic rod 8081 and a feeding rod group 8082 corresponding to the filling mold 10.

[0029] When the inner cylinder filling equipment 8 adopts this technology, the inner cylinder is manually placed in the feeding assembly 801. Then, the inner cylinder in the feeding assembly 801 will enter the corresponding row in the filling plate 802. Then, the positioning drive cylinder 806 is started to change the alignment position between the filling plate 802 and the feeding assembly 801, so as to fill other holes in the filling plate 802. When the filling plate 802 is filled as required, the rotation drive cylinder 807 is started, so that the vertical filling frame 804 carrying the filling plate 802 rotates to the horizontal. Then, the positioning drive cylinder 806 is started to effectively control the position of the filling frame 804 in the feeding station a, so as to align it with the filling mold 10 in the feeding station a. In this equipment, the positioning of the filling mold 10 and the positioning of the fireworks in the filling station c are both achieved using existing positioning technologies, such as sensor-assisted clamping cylinder positioning, or other positioning technologies used on conveyor belts.

[0030] The above description is merely an embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art.
