Description

Technical Field

[0001] This utility model relates to fireworks manufacturing machinery, and in particular to an integrated machine for manufacturing fireworks by drilling, inserting fuses, and fixing fuses. Background Technology

[0002] Fireworks are beautiful, dazzling, and auspicious. They bring people various festive, auspicious, magnificent, joyful, and enthusiastic scenes and moods. Nowadays, people often use bright beads that can bloom in various colors to make the inner tube, and then place the inner tube on the gunpowder (air-lifting powder) inside the outer tube. By lighting the fuse connected to the gunpowder, the gunpowder explodes, throwing the inner tube upward into the air to burn and explode, producing a sound and blooming in various colors at the same time. There are two main types of fireworks manufacturing processes. One involves placing an inner tube inside each outer tube of a molded outer tube (combined box type). The inner tubes are then connected in series using fuses within the space beneath the molded outer tube. Lighting one fuse at a time ignites all the inner tubes, resulting in a sequential fireworks display. The other type involves individual fireworks manufacturing, where each firework is fired individually. In this method, clay is first filled into a paper tube, followed by gunpowder. A fuse hole is then mechanically drilled in the paper tube between the clay and gunpowder. A cut fuse is inserted through this hole into the paper tube, and the exposed portion of the fuse is folded flat and secured to the outer wall of the paper tube with tape. The fuse-drilling, insertion, and securing processes in individual fireworks manufacturing are typically completed in three steps using three different machines (devices). This method requires significant equipment investment, occupies a large factory area, and necessitates the coordination of three operators, resulting in low production efficiency and high labor costs. Utility Model Content

[0003] To address the problems existing in the manufacturing of single fireworks in the prior art, this utility model provides a double-bang fireworks fuse insertion and fixing machine that completes the three processes of drilling fuse holes, inserting fuses, and fixing fuses on the same machine, saving equipment investment and factory area. Moreover, only one operator is needed to complete the three processes, improving production efficiency and reducing labor costs.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows: It includes a workbench and a turntable that can rotate at intervals on the workbench. The workbench is equipped with a drilling device, an insertion device, a fixing device, and a discharge device. The turntable is evenly spaced with four receiving seats for positioning firework paper tubes. Each receiving seat has several grooves that match the firework paper tubes. A firework paper tube input frame is provided on one side of the drilling device, and a firework paper tube output frame is provided on one side of the discharge device. The drilling device includes a pressure head I connected to a pressing cylinder and capable of fixing the firework paper tubes on the receiving seats, and a drill bit fixing plate connected to the drilling cylinder. The drill bit fixing plate is fixedly connected to the upper ends of several drill bits arranged at intervals. The lower end moves through the perforation guide plate and perforates the firework paper tube under pressure. The characteristic feature is that the insertion device includes an insertion cylinder fixed to the top plate and a support plate connected to the lower end of the piston rod of the insertion cylinder. The support plate is fixedly connected to the upper end of the wall plate. The lower end of the wall plate moves downward to press the firework paper tube. One side of the wall plate is connected to the movable module through a horizontally arranged dovetail groove. Several guide tubes corresponding to the lead holes on the firework paper tube are arranged between the top plate and the support plate. Guide grooves corresponding to the position and number of guide tubes are arranged on the side of the movable module combined with the wall plate. A cutting blade groove is arranged in the middle of the movable module, and a cutting blade is fixedly installed in the cutting blade groove. A pair of horizontally arranged guide tubes are arranged between the top plate and the wall plate. An active and driven rollers extend into the guide tube. The lead wire entering the guide tube moves downwards into the guide groove under the action of the active and driven rollers. One end of the movable module is connected to a bar with a round pin. A sleeve plate with a tapered pin hole is fitted onto the bar. When the wall panel presses down on the firework paper tube, the round pin can be inserted into the pin hole. The sleeve plate moves to the right under the action of a micro-cylinder, causing the bar and movable module to move to the right. The movable module cuts the lead wire through a dovetail groove and a driving cutting blade. The fixing device includes an inclined lifting cylinder. The upper end of the lifting cylinder is connected to a roller that can move on a guide rail, and the lower end's lifting piston rod passes through a guide block and is connected to the pressure head II. One end of the piston rod of the translation cylinder is connected to the pressure head II. Under the action of the lifting cylinder and the translation cylinder, the pressure head II moves forward and downward synchronously to the surface of the firework paper tube to press the exposed lead wire into a flattened lead wire. The lower end of the pressing cylinder is connected to the pressing block. A cutting blade is set on the pressing block between adjacent firework paper tubes. The receiving seat is equipped with a conveyor belt that can rotate left and right. A clamp is fixedly connected to the conveyor belt by a drag belt. The clamp moves to the right with the conveyor belt to clamp the transparent tape and then moves to the left. The clamp on the left-moving conveyor belt stretches the transparent tape and lays it on the firework paper tube. Under the pressure of the pressing block with a concave arc bottom and the action of the cutting blade, the stretched transparent tape is cut into segments and the flattened lead wire is pressed tightly on the surface of the firework paper tube.

[0005] The working process of this utility model is as follows: When the input roller drive motor is started and the firework paper tubes on the input frame are transported to the punching device position, the displacement sensor sends a signal, the input roller drive motor stops working, and the push cylinder I6 in the punching device works. The piston rod drives the push plate I5 to send a group of eight firework paper tubes evenly into the receiving seat 50 located on the turntable at the lower part of the punching device. When the push plate I5 returns to its original position, the pressure cylinder works at the same time, driving the pressure head I10 to press and fix the firework paper tubes. The punching cylinder 83 then works, the punching piston rod 82 moves downward and drives the drill bit fixing plate 74 and the drill bit on it to move downward synchronously, so that the drill bit drills into the firework paper tube, completing the punching. The drill bit returns to its original position, the turntable rotates 90 degrees clockwise so that the punched firework paper tubes enter the lower part of the insertion device 14, and the turntable stops rotating. The insertion cylinder 35 and servo motor 38 operate, causing the support plate 39, which is connected to the piston rod of the insertion cylinder, to move downwards. This causes the wall plate 98, which is fixedly connected to the support plate, to move downwards and press against the firework tube. At the same time, the movable template 54, which is movably connected to the wall plate through a horizontal dovetail groove, moves downwards. Simultaneously, the servo motor drives the active drive roller 57 and the driven drive roller to rotate, causing the lead wire 32 on the steering roller to move downwards in the guide tube and pass through the lead wire groove in the movable module into the lead wire hole at the bottom of the lead wire groove, which is aligned with the position of the lead wire groove. The lead wire is inserted between the gunpowder and mud in the firework tube. When the lead wire is fully inserted into the firework tube, the bar 41, which is connected to one end of the movable module, moves downwards to the lower end of the wall plate to press against the firework tube. The gap between the lower end of the movable module and the firework tube is 0.5-1.0 mm, the insertion cylinder stops working. Since the firework paper tube has been perforated, the pin on the bar is now precisely aligned with the pin hole in the sleeve 42, which is fixedly connected to one end of the small piston rod Y-5 of the micro cylinder. The micro cylinder Y-4 operates, causing the bar to move the movable module to the right. This causes the cutting blade on the movable module to cut the lead wire in the lead wire groove. After the lead wire is cut, the micro cylinder reverses its operation, returning the cutting blade to its original position. The height of the cutting blade on the movable module should ensure that the length of the cut lead wire exposed on the firework paper tube is the set height (generally higher than the firework paper tube). The length of the lead wire in the upper lead wire hole should be no less than 25-30 mm. After insertion, the support plate and the movable module return to their original position with the insertion cylinder (rising). The turntable then rotates 90 degrees clockwise to allow the inserted firework paper tube to enter the lower part of the fixed lead device 19. The turntable stops rotating, and the horizontal push cylinder 85 and the inclined lifting cylinder 86 work synchronously, causing the pressure head II 31 connected to the lower end of the lifting piston rod 89 connected to the lifting cylinder to move forward and downward to the lead wire position, pressing the lead wire 32 exposed outside the firework paper tube into a flattened lead wire 75. The horizontal push cylinder 85 and the lifting cylinder... After the pressure head II 31 returns to its original position, the cutting cylinder 86 moves upward and backward, driving the pressure block 94 downward. During the downward movement of the pressure block, the pulling roller 21 rotates under the motor, driving the conveyor belt to rotate to the right. This causes the clamp connected to the conveyor belt 20 via a drag belt to move quickly to the right and clamp the tape driven by the tape drive roller. Then, under the reverse rotation of the motor, the pulling roller 21 drives the conveyor belt and the clamp that has clamped the tape to rotate quickly to the left. Before the pressure block contacts the folded lead wire 75, the clamp pulls the tape from the right side to the left. On the left, the tape is laid horizontally on the folded lead wire. When the pressure block descends and begins to contact the folded lead wire, the tape is cut into eight pieces 79 by the cutting blade 78 on the pressure block. Under the pressure of the pressure head, the cut tapes fix the corresponding folded lead wires to the fireworks paper tube and simultaneously seal the lead wire holes, thus completing the fixing. The pressure block returns to its original position, and the turntable rotates 90 degrees clockwise, allowing the fixed fireworks paper tube to enter the discharge device position (the discharge device is opposite the insertion device, and the punching device is opposite the fixing device). The turntable stops working, and the push cylinder II... The operation of device 24 drives the extended push rod 25 and its connected pusher plate II 28 to move to the left, thereby pushing the firework paper tubes on the turntable onto the output roller 22 on the output frame 23 via pusher plate II, thus outputting the perforated, inserted, and secured firework paper tubes to the tube assembly machine. Simultaneously with the discharge process of the discharge device, the perforation, insertion, and securing devices perform their respective tasks. The turntable rotates clockwise at intervals, continuously completing the perforation, insertion, and securing of the firework paper tubes.

[0006] Compared with the prior art, the advantages of this utility model are: this utility model can complete the three processes of drilling, insertion and fixing on the same equipment, saving equipment investment and factory area, and only one operator is needed to safely complete the three processes, which improves production efficiency and reduces labor costs.

The turntable is fixedly connected to the upper end of the rotating shaft 43 via a connecting plate 49. The upper section of the rotating shaft is connected via a bearing 48, a bearing seat 44, and a bearing cover 47. The lower end of the rotating shaft is connected to the main motor 46 via a gear pair 45 (a pair of reduction gears). The bearing seat is fixed on the bottom surface of the workbench. The workbench is equipped with a punching device 4, an inserting device 14, a fixing device 19, and a discharge device (not shown in the figure). The turntable is evenly spaced with four receiving seats 50 for positioning firework paper tubes 9. Each receiving seat has eight grooves that match the firework paper tubes. The turntable is located on the workbench 11. A firework paper tube input frame 1 is set on one side of the punching device. The input frame includes input rollers 2 spaced on the input frame and a pusher plate I5 and a pusher cylinder I6 located at one end of the firework paper tube. One end of the pusher plate I is connected to a guide rod I7 and a support. The support plate I8 is connected to the piston rod in the push cylinder I6. The input roller rotates under the action of the chain, sprocket, and motor. An output frame 23 is provided on one side of the discharge device. Output rollers 22 are spaced apart on the output frame. The output rollers rotate under the action of the chain, sprocket, and motor. The punching device includes a pressure head I10 connected to the pressure cylinder piston rod 84 of the pressure cylinder 80 and capable of fixing the firework paper tube on the receiving seat, and a drill bit fixing plate 74 connected to the punching cylinder. The drill bit fixing plate is set at... On bracket I12, the drill bit fixing plate is fixedly connected to the upper ends of eight spaced-apart drilling bits 73. The drilling guide rod 95 moves through the drilling support plate 96, and the lower end of the drilling bit moves through the drilling guide plate 65 and drills holes (lead holes) in the firework paper tube under pressure. The diameter of the lead hole (3.2 mm) is larger than the lead wire (lead diameter 1.7 mm). The drilling guide plate and the drill bit fixing plate are connected by a spring 63 and a connecting post 64 (for quick return to the original position after drilling).The insertion device 14 includes an insertion cylinder 35 fixed on the top plate 33 and a support plate 39 connected to the lower end of the insertion piston rod 59 of the insertion cylinder. The support plate is fixedly connected to the upper end of the wall plate 98. The lower end of the wall plate can press the firework tube by moving downward. One side of the wall plate is connected to the movable module 54 through a horizontally set dovetail groove 58. The left end of the wall plate is L-shaped. The left end of the movable module falls into the left end of the closed plate. The lower end of the movable module is 1-2 mm higher than the lower end of the wall plate. Several guide tubes 36 are provided between the top plate and the support plate, with positions corresponding to the lead holes 61 on the firework tube 9. The upper end of the guide tube moves through the top plate 33, and the lower end passes through the support plate 39 and is fixed on the support plate. The support plate is set on the end plate 62. Guide grooves 40 corresponding to the position and number of guide tubes are provided on the side of the movable module combined with the wall panel. A cutting blade groove 55 is provided in the middle of the movable module. A cutting blade 52 is fixed in the cutting blade groove at an incline (45 degrees) with fastening screws 51. A pair of active drive rollers 57 and driven drive rollers 53 that can extend into the guide tube are horizontally arranged between the top plate and the wall panel. The active drive rollers are driven to rotate by the drive shaft 56. One end of the drive shaft is connected to the servo motor 38 fixed on the bracket II 13. The guide tube is cut by the active drive roller 57 (i.e., the guide tube passes through the drive roller). After the active roller housing 37 is disconnected, the lead wire 32, which enters the guide tube, can move downward into the guide groove under the action of the active drive roller 57 and the driven drive roller 53. One end of the movable module is connected to a bar 41, on which a round pin Y-3 is provided. The lower part of the bar is provided with a sleeve plate 42, on which a pin hole Y-1 with a tapered opening Y-2 is provided. When the wall panel presses the firework paper tube, the round pin can be inserted into the pin hole. The sleeve plate moves to the right under the action of the micro cylinder and drives the bar and the movable module to move to the right. The movable module cuts the lead wire 32 through the dovetail groove and drives the cutting blade 52. The lead wire enters the lead tube from the lead wire roller through the turning roller 34. The turning roller is set on the beam plate I 60, and the beam plate I is fixed on the worktable.The fixing device 19 includes an inclined lifting cylinder 86. The upper end of the lifting cylinder is connected to a roller 88 that can move on a guide rail 87, and the lower end of the lifting piston rod 89 passes through a guide block 90 and is connected to a pressure head II 31. The guide block is connected to one end of the piston rod of a horizontal pushing cylinder 85 (the horizontal pushing cylinder is fixed on a bracket III 26). Under the action of the lifting cylinder and the horizontal moving cylinder, the pressure head II moves forward and downward synchronously to the surface of the firework paper tube to press the exposed lead wire into a flattened lead wire 75. The glue-pressing cylinder 69 is fixed on the beam plate II 67, which is set on the column 72. The lower end of the guide rod II 71 is connected to the glue-pressing block, and the upper end moves through the support plate II 68 and the beam plate II 67. The glue-pressing piston of the glue-pressing cylinder... The lower end of the rod 70 is fixedly connected to the pressure block 94. A cutting blade 78 is fixedly installed in the pressure strip groove 66 on the pressure block between adjacent firework paper tubes. The receiving seat is equipped with a conveyor belt 20 that can rotate left and right. A clamp is fixedly connected to the conveyor belt by a pull plate 29-6. The clamp includes an upper clamp rod 29-1 and a lower clamp rod 29-3 that is movably connected in the middle by a hinge shaft 29-3 (equivalent to a scissor connection). One end of the hinge shaft is fixed to the pull plate, and the pull plate is fixedly connected to the conveyor belt 20. One end of the upper clamp rod and the lower clamp rod are connected to opposite clamping heads 29-7. The other end of the upper clamp rod and the lower clamp rod are connected to both ends of a telescopic rod 29-5 equipped with a miniature telescopic cylinder 9-4. The other end of the transparent tape is output through the tape drive roller 15 and the tape driven roller 81. When the open clamping block moves to the right with the conveyor belt 20, the conveyor belt rotates on the tape drive roller 16 and the tape driven roller 18. Under the action of the displacement sensor, when the clamping block clamps one end of the transparent tape 17, the displacement sensor sends a signal to reverse the tape pulling drive roller and drive the conveyor belt to move in the opposite direction (to the left). When the clamped end of the transparent tape reaches the leftmost firework paper tube, under the action of another displacement sensor, the tape pulling drive roller stops rotating, and then the tape cutting blade descends to cut the transparent tape. Then the pressing block presses the cut transparent tape onto the firework paper tube. When the lead wire is pressed into a flattened lead wire, the displacement sensor sends a signal to make the tape pulling drive roller rotate in the forward direction and drive the conveyor belt and clamp to move in the forward direction (to the right) synchronously. When the clamping block clamps one end of the transparent tape, the above movement is repeated, and the tape laying, tape cutting and fixing can be continuously completed. Alternatively, a structure capable of clamping transparent tape can be used to achieve fixation. The discharge device includes a push cylinder II 24 and an extended push rod 25 connected to the push cylinder II. The middle end of the extended push rod movably passes through a support plate III 27, which is mounted on a bracket III 26. The end of the extended push rod is connected to the push cylinder plate II 28 via a cantilever frame 77. The push cylinder plate II moves to the left with the extended push rod, pushing the firework paper tube onto the output roller 22 of the output frame 23.

[0020] The lead wire from the guide tube enters the guide groove 40. After the firework paper tube is punched, it is restricted at both ends by floating pressure rollers 97 within the receiving plate 50 on the turntable 3. The two ends of the pressure rollers are set on the guide post 91 with adjusting nuts 93. The guide post is equipped with a pressure (compression) spring 92. Under the action of the pressure spring, the adjusting nut makes the pressure roller both press the firework paper tube tightly and push the firework paper tube out of the receiving seat onto the output frame under the action of the push plate II 28 in the discharge device. Due to the action of the pressure roller, the position of the firework paper tube in the receiving plate does not change when it rotates 90 with the receiving plate. When the receiving plate rotates to the insertion position, under the action of the displacement sensor, the lead wire hole on the firework paper tube is aligned with the guide groove. In addition, the cross-sectional area of ​​the lead wire hole is larger than the cross-sectional area of ​​the lead wire, which allows the lead wire to pass smoothly through the guide groove and move downward in a straight line. After the lead wire enters the lead wire hole, it enters the firework paper tube. When the bar 41, which is connected to one end of the movable module, moves downward to the lower end of the wall plate 98 to press the firework tube 9 (the bar is 2 mm away from the sleeve plate), the insertion cylinder 35 stops working. At this time, the round pin Y-3 on the bar is just inside the pin hole Y-1 in the sleeve plate 42, which is fixedly connected to one end of the small piston rod Y-5 of the micro cylinder Y-4. The upper end of the pin hole YY has a tapered opening Y-2, and the lower end of the round pin is tapered. The clearance between the round pin and the pin hole is controlled at 0.3-0.5 mm, and the fit length is 3-4 mm. This allows the round pin to be smoothly inserted into the pin hole and also allows the sleeve plate to move smoothly to the right on the support platform Y-6. The micro cylinder Y-4 works to make the bar drive the movable module to move to the right, so that the cutting blade on the movable module cuts the lead wire in the lead wire groove. After the lead wire is cut, the micro cylinder works in the opposite direction to make the cutting blade return to its original position.

[0021] The clamp includes an upper clamping rod 29-1 and a lower clamping rod 29-2 connected in the middle by a hinge pin 29-3 (connected like scissors). One end of the hinge pin is fixed to the pull plate 29-6, and the pull plate is fixedly connected to the conveyor belt 20. One end of the upper clamping rod and the lower clamping rod are connected to opposite clamping blocks 29-7, and the other end of the upper clamping rod and the lower clamping rod are connected to both ends of a telescopic rod 29-5 equipped with a miniature telescopic cylinder 9-4. As the open clamping block moves to the right with the conveyor belt 20, under the action of the displacement sensor, when the clamping block clamps the transparent tape, the displacement sensor sends a signal to reverse the adhesive-pulling drive roller, causing the conveyor belt to move in the opposite direction (to the left). When one end of the clamped transparent tape reaches the leftmost firework tube, under the action of another displacement sensor, the adhesive-pulling drive roller stops rotating, and then the cutting blade descends to cut the transparent tape. Then the pressing block presses the cut transparent tape onto the firework tube. When the lead wire is pressed into a flattened lead wire, the displacement sensor sends a signal to rotate the adhesive-pulling drive roller in the forward direction and drive the conveyor belt and clamp to move synchronously in the forward direction (to the right). When the clamping block clamps the transparent tape, the above movement is repeated, which can continuously complete the laying, cutting, and fixing of the tape.

[0022] The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any aspects not mentioned, such as PLC control, limit switches and displacement sensors in the automatic control device, are existing technologies. Although this utility model has been described in detail with reference to specific embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of protection of the claims of this utility model.
