Description

Technical Field

[0001] This utility model specifically relates to a moving and positioning device for the filling of the inner tube of combined fireworks. Background Technology

[0002] In the fireworks production process, the filling of fireworks tubes requires the connection of multiple processes, including "conveyance, positioning, transfer, and docking / unloading." Existing transfer devices have significant technical defects, making it difficult to meet the demands for efficient, safe, and precise production. Specific problems include: Traditional transfer devices often have lifting mechanisms with only single-height adjustment, allowing connection to only a single process (such as connecting only the conveyor or the unloading device). To achieve multi-process connection, multiple transfer devices are required, increasing equipment investment costs and causing waiting time due to multiple connections, resulting in low overall production efficiency. Furthermore, the fireworks production environment contains flammable and explosive substances, and some existing transfer devices are electrically driven (such as motors and electric push rods). During operation, these devices are prone to leakage due to aging wiring, short circuits, etc., posing a fire or explosion hazard and failing to meet the safety production standards of the fireworks industry. Utility Model Content

[0003] The present invention aims to at least partially solve one of the problems existing in the existing related technologies. To this end, the present invention proposes a moving and positioning device for filling the inner tube of combined fireworks. A moving and positioning device for filling the inner tube of a combination firework includes a frame, on which a horizontal transfer mechanism and a two-stage lifting mechanism are respectively arranged; the horizontal transfer mechanism includes a movable seat and a first cylinder for driving the movable seat to move, the movable seat is movably mounted on the frame via a slide rail slider, and N clamping mechanisms are evenly distributed and spaced along its transverse direction on the movable seat; the two-stage lifting mechanism includes N-1 lifting platforms evenly distributed and spaced along the transverse direction of the frame, the clamping mechanisms are arranged one-to-one with the lifting platforms, and a pneumatic drive component capable of driving the lifting platforms to lift in two stages is correspondingly arranged between the frame and the lifting platforms.

The second cylinder is disposed on the lower side of the lifting platform, and a connecting block is disposed on the drive shaft of the second cylinder. The third cylinder is disposed on the frame and is disposed opposite to the second cylinder. The drive shaft of the third cylinder is connected to the connecting block.

[0005] In one embodiment, a single-stage lifting mechanism is respectively provided on the frame and on both sides of the two-stage lifting mechanism; the single-stage lifting mechanism includes a receiving platform and a fourth cylinder provided on the frame that can drive the receiving platform to move up and down, the distance between the receiving platform and its adjacent lifting platform is equal to the distance between two adjacent lifting platforms, and the driving stroke of the fourth cylinder is equal to the driving stroke of the third cylinder.

[0006] In one embodiment, the lifting platform includes an upper plate and a lower base plate, and a plurality of guide shafts connected between the upper plate and the lower base plate.

[0012] In summary, the advantages of this utility model over the prior art are: This utility model uses a two-stage pneumatic drive component consisting of a "second cylinder + a third cylinder" to achieve precise switching between three heights of the lifting platform: "lowest docking with external conveying equipment - intermediate transfer height - highest docking with external unloading device".

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1 to 5 The present invention preferably provides a moving and positioning device for filling the inner tube of a combined firework, comprising a frame 1, characterized in that: a horizontal transfer mechanism and a two-stage lifting mechanism are respectively provided on the frame 1; the horizontal transfer mechanism includes a movable seat 2 and a first cylinder 3 for driving the movable seat 2 to move, the movable seat 2 is movably mounted on the frame 1 via a slide rail slider, and N clamping mechanisms 4 are evenly distributed and spaced along its transverse direction on the movable seat 2; the two-stage lifting mechanism includes N-1 lifting platforms 5 evenly distributed and spaced along the transverse direction of the frame 1, the clamping mechanisms 4 and the lifting platforms 5 are arranged in a one-to-one correspondence, and a pneumatic drive component 6 capable of driving the lifting platforms 5 to lift in two stages is correspondingly provided between the frame 1 and the lifting platforms 5.

[0015] Specifically, the frame serves as the overall support base, and the movable seat is slidably mounted on the frame via a slide rail slider. In the initial state, the movable seat is in the position to be transferred under the reset action of the first cylinder. N clamping mechanisms evenly distributed along the horizontal direction on the movable seat correspond one-to-one with N-1 lifting platforms evenly distributed along the horizontal direction on the frame, forming a "clamping-lifting" alignment relationship to ensure that each clamping mechanism can accurately connect with the corresponding lifting platform.

[0016] Furthermore, the pneumatic drive components can drive the lifting platform to achieve two-stage lifting, thus enabling the lifting platform to have at least three height states formed by the superposition of the two lifting strokes: Minimum height: Adaptable to external conveying equipment for receiving firework tubes to be processed or collecting firework inner tubes that have been filled with bulk solid materials; Intermediate transfer height: Matches the clamping height of the clamping mechanism, making it easy for the clamping mechanism to grab or place the fireworks tubes on the lifting platform; Maximum height: Adapted to filler feeding device for receiving and filling fillers in fireworks tubes.

[0017] The lifting platform is first raised to the middle height by a two-stage pneumatic drive component. This height is perfectly matched with the clamping height of the clamping mechanism on the moving seat. At the same time, the firework tube on the lifting platform has been pre-positioned by the positioning block and precisely aligned with the clamping mechanism. The clamping mechanism clamps and fixes the firework tube on the lifting platform to ensure that the firework tube does not shift or fall off during the transfer process.

[0018] After the clamping mechanism secures the fireworks tube, the two-stage pneumatic drive components move in opposite directions, lowering the lifting platform from its intermediate height to its lowest point. This step prevents interference between the lifting platform and other components of the frame during the transfer process, and also ensures that the fireworks tube driven by the clamping mechanism is in a more stable transfer posture.

[0019] The first cylinder is activated, driving the moving seat to move laterally along the slide rail slider, accurately transferring the clamping mechanism holding the fireworks tube to the adjacent lifting platform. The layout design of "N clamping mechanisms and N-1 lifting platforms" realizes the transfer between adjacent platforms.

[0020] Once the movable seat is in place, the two-section pneumatic drive components of the adjacent lifting platform are activated, causing the lifting platform to rise from its lowest height to its middle height, aligning with the height of the fireworks tube held by the clamping mechanism, thus providing support for the placement of the fireworks tube.

[0021] The clamping mechanism reverses its movement, like a double-headed cylinder resetting, releasing the clamp on the fireworks tube. The fireworks tube is then placed smoothly on the adjacent lifting platform, completing one transfer between the adjacent platforms.

[0022] After the clamping mechanism is released, the two-stage pneumatic drive components of the adjacent lifting platform continue to operate, raising the lifting platform from its intermediate height to its maximum height. This height precisely aligns with the discharge port of the external filling material unloading device, meeting the height requirements of the filling operation.

[0023] The external feeding device is activated to deliver filling material into the firework tube on the lifting platform, completing the filling process. After filling, the lifting platform can be lowered to the lowest height by pneumatic drive components according to the needs of subsequent processes, so as to transfer the filled firework tube to downstream equipment.

[0024] Furthermore, the pneumatic drive component 6 includes a second cylinder 61 and a third cylinder 62. The second cylinder 61 is disposed on the lower side of the lifting platform 5, and a connecting block 63 is disposed on the drive shaft of the second cylinder 61. The third cylinder 62 is disposed on the frame 1 and is disposed opposite to the second cylinder 61. The drive shaft of the third cylinder 62 is connected to the connecting block 63.

[0025] Specifically, the drive shafts of the second and third cylinders are both in a retracted state. At this time, the two drive shafts lift the connecting block upward together, so that the connecting block drives the lifting platform to the highest height to connect with the filling material unloading device.

[0026] When the lifting platform needs to be adjusted from the highest height to the intermediate height: the second cylinder starts first, and its drive shaft extends in the extension direction by the amount of its own drive stroke; since the drive shaft of the second cylinder is connected to the connecting block, the extension action will push the connecting block to move downward, thereby driving the lifting platform to descend synchronously; at this time, the third cylinder keeps its drive shaft in the retracted state and does not move, and the descent stroke of the lifting platform is equal to the drive stroke of the second cylinder; when the second cylinder reaches its maximum extension stroke, the lifting platform is stable at the intermediate height and matches the transfer height of the clamping mechanism.

[0027] When the lifting platform needs to be adjusted from the middle height to the lowest height: with the second cylinder in the extended state and the connecting block position unchanged, the third cylinder is activated, and its drive shaft extends in the extension direction by its own drive stroke; the third cylinder drive shaft further pushes the lifting platform downward through the connecting block, and the descent stroke at this time is the drive stroke of the third cylinder; the total extension of the two cylinder drive shafts is "the stroke of the third cylinder + the stroke of the second cylinder", which drives the lifting platform to descend to the lowest height and connect with the external conveying equipment.

[0028] Furthermore, a single-stage lifting mechanism is respectively provided on the frame 1 and on both sides of the two-stage lifting mechanism; the single-stage lifting mechanism includes a receiving platform 11 and a fourth cylinder 12 provided on the frame 1 to drive the receiving platform 11 to move up and down. The distance between the receiving platform 11 and its adjacent lifting platform 5 is equal to the distance between two adjacent lifting platforms 5, and the driving stroke of the fourth cylinder 12 is equal to the driving stroke of the third cylinder 62.

[0029] Specifically, the distance between the receiving platform and the lifting platform on the frame is the same as the distance between adjacent lifting platforms, and the stroke of the fourth cylinder driving the receiving platform is the same as the stroke of the third cylinder. The fourth cylinder can drive the receiving platform to lift and lower, precisely matching the "intermediate transfer height" for temporarily storing firework tubes, supplementing the clamping mechanism and the transfer gap of the lifting platform, or assisting in docking the conveying equipment at the "minimum docking height," diverting and transferring pressure, and achieving continuous and flexible transfer of firework tubes. The receiving platform can serve as a transfer platform for transferring firework tubes; during the transfer process, the fourth cylinder is in a retracted state, and after the transfer is completed, the fourth cylinder extends to support and position the firework tube.

[0030] There is also a position signal when the grippers open to ensure that the grippers are fully open when gripping the inner tube of the fireworks, thus avoiding collisions caused by grippers not being fully open.

[0031] Furthermore, the lifting platform 5 includes an upper plate 51 and a lower base plate 52, and a plurality of guide shafts 53 connected between the upper plate 51 and the lower base plate 52. The guide shafts 53 are movably inserted into the frame 1 through bearings, and the second cylinder 61 is disposed on the upper side of the lower base plate 52.

[0032] Specifically, through the structural combination of "upper plate bearing + lower base plate force transmission + guide shaft and bearing guidance", the lifting platform can ensure the synchronization and levelness of the upper and lower plates in the process of realizing three-stage height adjustment (highest, middle and lowest). At the same time, it can reduce the resistance of movement through low friction guidance, avoid the displacement, falling or filling deviation of the fireworks tube due to unstable lifting, and adapt to the requirements of fireworks production for equipment stability and precision.

[0033] Furthermore, the frame 1 is provided with a position switch 13 that can cooperate with the movable seat 2; when the first cylinder 3 is at its maximum stroke, the movable seat cooperates with the position switch 13 to cause the position switch 13 to send an electrical signal.

[0034] Specifically, the position switch on the frame is used to accurately detect the displacement endpoint of the moving seat. When the first cylinder drives the moving seat to move along the slide rail to its maximum stroke, i.e., the target position required for transfer, the moving seat contacts or senses the position switch, triggering the position switch to send an electrical signal. This electrical signal can be transmitted to the control system as a command for the moving seat to be in place, which is used to control subsequent actions such as clamping / releasing of the clamping mechanism and adjusting the height of the lifting platform, ensuring accurate movement of the moving seat and orderly coordination of all mechanisms, thus improving the accuracy of automated control.

[0035] Furthermore, the clamping mechanism 4 includes a horizontally arranged double-headed cylinder 41 and clamping plates 42 respectively disposed on the drive shafts on both sides of the double-headed cylinder 41.

[0036] Specifically, the clamping mechanism uses a horizontally arranged double-headed cylinder as its power source, with drive shafts on both sides connected to clamping plates. When the firework tube needs to be clamped, the drive shafts on both sides of the double-headed cylinder retract inward simultaneously, causing the clamping plates to move in opposite directions, forming a symmetrical clamping force on the firework tube on the lifting platform or receiving platform to prevent it from shifting or falling during transfer. When the firework tube needs to be released, the drive shafts on both sides of the double-headed cylinder extend outward simultaneously, causing the clamping plates to separate in the opposite direction, releasing the firework tube. This achieves the core functions of "precise clamping - stable transfer - smooth release," adapting to the overall transfer process.

[0037] Furthermore, the lifting platform 5 is equipped with a dust removal mechanism; the dust removal mechanism includes an exhaust pipe 43 and a cover 44 connected to the upper end of the exhaust pipe 43. The lower end of the exhaust pipe 43 is connected to an exhaust fan. The cover 44 covers the lower side of the upper plate 51. The upper plate 51 is provided with a number of mesh holes 45 at intervals.

[0038] Specifically, the upper plate of the lifting platform generates dust during the filling of fireworks tubes, and the mesh on the upper plate provides a falling channel for the dust; the cover covers the lower side of the upper plate, forming a closed collection space; an external exhaust fan generates negative pressure inside the cover through the exhaust pipe, sucking the dust generated during filling into the cover through the mesh, and then extracting it through the exhaust pipe for collection, realizing real-time dust removal during the filling process and avoiding the safety risks of dust accumulation pollution or dust explosion.

[0039] Furthermore, the upper end of the lifting platform 5 is provided with a number of positioning blocks 46 at intervals, and a positioning area for positioning and placing firework tubes is formed between the number of positioning blocks 46.

[0040] Specifically, several positioning blocks are spaced apart at the top of the lifting platform, forming a positioning area that matches the shape of the fireworks tube. When the fireworks tube is placed, it is embedded in the positioning area, and the positioning blocks limit the fireworks tube from the circumference, preventing it from shifting or tilting laterally during lifting and transfer. This ensures that the clamping mechanism can accurately hold the fireworks and the unloading device can accurately connect, thus improving the positioning accuracy of the overall process.

[0041] Furthermore, an infrared sensor 47 is installed on the upper end of the lifting platform 5.

[0042] Specifically, the infrared sensors are waterproof and explosion-proof. The infrared sensors at the top of the lifting platform are used to detect the status of the fireworks tubes on the platform in real time. When the fireworks tubes are placed on the lifting platform or in the positioning area, the infrared sensors transmit and receive infrared signals to determine whether the fireworks tubes are "placed in place," such as whether they are fully embedded in the positioning area or whether they are tilted or offset. The detection signals are transmitted to the control system. If the fireworks tubes are confirmed to be in place, the system can trigger subsequent actions such as clamping the clamping mechanism and adjusting the height of the lifting platform. If no fireworks tubes are detected or the position is off, the subsequent actions are paused to avoid empty transfer or loading / transfer failures caused by positional deviations, thereby improving the reliability and safety of the automated operation of the device.
