Description

Technical Field

[0001] The utility model relates to the field of fireworks production equipment, and particularly relates to a medicine mixing and conveying chain device for a firecracker inner cylinder filling production line. Background Art

[0002] The traditional filling of firecracker inner cylinders is basically done by pure manual work. The work of gunpowder mixing is basically manual operation, with low production efficiency, high labor intensity, high cost and high danger. Mechanization, automation and intelligence are the inevitable development trends.

[0003] With the development of automation, the mixing of gunpowder for filling firecracker inner cylinders has started to adopt an automated method. However, since static electricity may be generated due to friction during the mixing and transmission of gunpowder, especially in a dry environment, if this static electricity accumulation is not effectively released, it may cause sparks, leading to accidental explosions or fires. At the same time, the structures of most automated devices are relatively complex. Although the production efficiency and accuracy are improved, new problems are also brought, such as equipment failures, sensor malfunctions or program errors. These problems may lead to deviations in the mixing ratio of gunpowder or inaccurate filling of gunpowder, thereby affecting the performance of firecrackers. Summary of the Utility Model

[0004] Aiming at the problems in the prior art that fire and explosion are easily caused due to static electricity accumulation during the automated medicine mixing process, and equipment or program failures are likely to occur in complex automated structures, the utility model provides a medicine mixing and conveying chain device for a firecracker inner cylinder filling production line to solve the above problems.

[0005] The present application provides a medicine mixing and conveying chain device for a firecracker inner cylinder filling production line, which includes a water tank mechanism and a power mechanism. The water tank mechanism includes a frame and a water tank fixed above the frame. The power mechanism includes a power machine and a conveying chain respectively arranged below and above the water tank. A number of sliding platform trolleys are detachably installed on the conveying chain, and the power machine drives the conveying chain to drive the sliding platform trolleys to perform uniform circular motion in the water tank, and the sliding platform trolleys sequentially pass through a number of medicine mixing mechanisms arranged at equal intervals on the side of the water tank.

[0006] By adopting the above technical solutions, water can be injected into the water tank so that the water surface is slightly higher than the highest surface of the conveying chain, enabling the powder and other impurities generated during the medicine mixing process to fall into the water tank, isolating the combustible medicine with water, and avoiding the natural ignition and explosion of the medicine. The power machine drives the conveying chain to drive the sliding platform trolleys, making the entire medicine mixing and conveying process automated, reducing manual intervention, improving production efficiency and output, and at the same time reducing errors. The conveying chain adopts a compact circular motion mode, making the equipment occupy a small area and facilitating the realization of an efficient production layout in a limited space.

[0007] In some specific embodiments, the conveying chain is arranged in a loop parallel to the upper surface of the water tank, and an induction switch is arranged inside the conveying chain corresponding to the position of the medicine mixing mechanism.

[0008] By adopting the above technical solution, the position of the sliding table trolley is sensed by the induction switch. When the sliding table trolley moves to the position corresponding to the medicine mixing mechanism, the induction switch can send a signal to the power machine to stop working, so that the sliding table trolley accurately stops at the corresponding position of the medicine mixing mechanism, which is beneficial to fully and evenly carry out the medicine mixing work. When a medicine mixing process is completed, the power machine drives the sliding table trolley to move to the position of the next medicine mixing mechanism, which can ensure that the medicine mixing process is carried out accurately and error-free.

[0009] In some specific embodiments, driving rollers for tensioning and driving the movement of the conveying chain are arranged at both ends inside the water tank, and one of the driving rollers is connected to the power machine at the bottom.

[0010] By adopting the above technical solution, the arrangement of the driving rollers at both ends can effectively maintain the tension of the conveying chain and prevent the chain from loosening. This ensures that the sliding table trolley maintains a stable speed and trajectory during movement, improving the stability and consistency of the mixing and conveying processes. At the same time, by directly connecting the driving rollers to the power machine, efficient power transmission is achieved, reducing intermediate transmission links, lowering energy loss, and improving the transmission efficiency of the entire system. The simple structure makes the maintenance of the power mechanism more convenient.

[0011] In some specific embodiments, the sliding table trolley is clamped to the outside of the conveying chain through a chain joint, and a stop block and a directional wheel are respectively arranged on one side of the bottom of the sliding table trolley close to and away from the conveying chain.

[0012] By adopting the above technical solution, the sliding table trolley is clamped to the outside of the conveying chain through a chain joint, simplifying the installation and disassembly process. This not only improves the flexibility of the system but also makes the maintenance and replacement of the sliding table trolley more convenient, reducing production downtime. The arrangement of the stop block and the directional wheel can effectively limit the movement range of the sliding table trolley and prevent it from shifting or swinging during transportation, thereby improving the stability and accuracy of the transportation process.

[0013] In some specific embodiments, support columns extend upward from the end points of the upper surface of the base, and a tray for placing fireworks is detachably arranged above the support columns.

[0014] By adopting the above technical solution, the support columns provide additional structural support. In the case of the detachable tray, the stability of the tray when carrying fireworks is ensured, avoiding the tray from tilting or moving due to external forces or vibrations, thereby improving the stability of the fireworks placement. The detachable design of the tray makes it more convenient for maintenance or cleaning, thus reducing the cleaning difficulty and time and improving the maintenance efficiency.

[0015] In some specific embodiments, on the upper surface of the tray, a firecracker cake edge stop adapted to the size of the firecrackers is provided on the side close to the conveying chain.

[0016] By adopting the above technical solution, the firecracker cake edge stop can effectively prevent the firecrackers from sliding or displacing due to vibration or inclination during transportation, ensuring the stability of the firecrackers on the tray, reducing the occurrence of accidents. The design of the firecracker cake edge stop can help accurately position the firecrackers on the tray. Especially when the firecrackers are moved through the conveying chain, while preventing the firecrackers from sliding, the edge stop also plays a protective role, reducing the damage of the firecrackers caused by friction or collision and ensuring the integrity of the firecrackers.

[0017] In some specific embodiments, the firecracker cake edge stop includes a fixing plate fixed to the upper surface of the tray by bolts, and a plurality of protruding baffle plates arranged on the edge of the fixing plate and adapted to the shape of the firecrackers.

[0018] In some specific embodiments, on the side edge of the upper surface of the tray perpendicular to the moving direction of the conveying chain, a firecracker fixing bracket is provided, and a protruding fixing spring piece is arranged on the inner side of the firecracker fixing bracket.

[0019] By adopting the above technical solution, the combination of the firecracker fixing bracket and the protruding fixing spring piece on the inner side can fix the firecrackers more firmly, preventing them from shifting or inclining due to vibration or external force during transportation. The fixing spring piece provides additional gripping force. Since the sliding table trolley moves in a uniform circular motion during operation and generates centrifugal force, it can prevent the firecrackers from being thrown out by the centrifugal force, further enhancing the fixing effect of the firecrackers.

[0020] In some specific embodiments, the mixing mechanism includes a fixing seat arranged outside the water tank. The upper part of the fixing seat extends upward above the water tank and is provided with a mixing device, and the mixing device has a size adapted to the sliding table trolley.

[0021] By adopting the above technical solution, the mixing device is installed on the fixing seat outside the water tank and extends upward above the water tank, making the space occupied by the whole device more compact and reasonable. This design makes full use of the space above the water tank, saves the space in the working area, and is suitable for the environment with limited production sites. The operator can set the corresponding fixing seat and mixing device according to the actual number of mixing processes and the site conditions, enabling the equipment to be flexibly applied to different production scenarios. Whether dealing with drugs of different specifications or facing different production requirements, this design can provide sufficient flexibility.

[0022] In some specific embodiments, a clamping part is further provided at the position corresponding to the upper part of the sliding table trolley on the mixing device.

[0023] By adopting the above technical solution, the clamping part can firmly fix the tray on the upper part of the sliding table trolley, and at the same time clamp the tray upward to closely cooperate with the medicine mixing device, so that it remains stable during the medicine mixing process, preventing uneven medicine mixing caused by vibration or external force, and helping to ensure the accuracy and consistency of the medicine mixing process.

[0024] This application mainly solves the problems that in the prior art, during the automated medicine mixing process, fire and explosion are easily caused due to static electricity accumulation, and equipment or program failures are likely to occur in the complex automated structure. This application proposes a medicine mixing and conveying chain device for a firecracker inner cylinder filling production line. The water tank design effectively isolates combustible drugs to ensure production safety; the automated medicine mixing process reduces manual intervention, improves production efficiency and consistency; the precise positioning of the induction switch and the clamping part ensures the uniform mixing of the medicine powder in each medicine mixing process, improving the quality and stability of the final product. The compact layout of the conveying chain and the sliding table trolley not only saves space but also simplifies maintenance, adapting to different production requirements, thus significantly improving the efficiency and reliability of the entire production line.

Therefore, the following detailed description should not be taken in a limiting sense, and the scope of the present utility model is defined by the appended claims.

[0032] The present application proposes a mixing and conveying chain device for a firework inner cylinder filling production line. Figure 1 The structural schematic diagram of the mixing and conveying chain device according to an embodiment of the present utility model is shown. As shown in the figure, the device includes a water tank mechanism 01 and a power mechanism 02; the water tank mechanism 01 includes a frame 011 and a water tank 012 fixedly arranged above the frame 011; the power mechanism 02 includes a power machine 021 and a conveying chain 022 respectively arranged below and above the water tank 012; a plurality of sliding platform trolleys 04 are detachably installed on the conveying chain 022, and the power machine 021 drives the conveying chain 022 to drive the sliding platform trolleys 04 to perform uniform circular motion in the water tank 012. The sliding platform trolleys 04 sequentially pass through a plurality of mixing mechanisms 03 arranged at equal intervals on the side of the water tank 012. Through the above scheme, water can be injected into the water tank 012 so that the water surface is slightly higher than the highest surface of the conveying chain 022, so that the powder and other impurities generated during the mixing process fall into the water tank 012, and the combustible drugs are isolated by water, avoiding spontaneous ignition and explosion caused by the drugs; the power machine 021 drives the conveying chain 022 to drive the sliding platform trolleys 04, making the whole mixing and conveying process automated, reducing manual intervention, improving production efficiency and output, and at the same time reducing errors. The conveying chain 022 adopts a compact circular motion mode, making the equipment occupy a small area and being conducive to realizing an efficient production layout in a limited site. The specific principle and structure are described in detail in combination with Figures 2-3 the application in

[0033] Figure 2 The installation schematic diagram of the power mechanism according to a specific embodiment of the present utility model is shown, as Figures 1-2As shown, the conveying chain 022 is arranged in a loop parallel to the upper surface of the water tank 012, and an induction switch 05 is arranged at the position corresponding to the medicine mixing mechanism 03 on the inner side of the conveying chain 022. By using the induction switch 05 to sense the position of the sliding table trolley 04, when the sliding table trolley 04 moves to the position corresponding to the medicine mixing mechanism 03, the induction switch 05 can send a signal to stop working to the power machine 021, so that the sliding table trolley 04 accurately stops at the corresponding position of the medicine mixing mechanism 03, which is beneficial to fully and evenly carry out the medicine mixing work. When a medicine mixing process is completed, the power machine 021 drives the sliding table trolley 04 to move to the position of the next medicine mixing mechanism 03, which can ensure that the medicine mixing process is carried out accurately without error.

[0034] In a specific embodiment, driving rollers 023 for tensioning and driving the movement of the conveying chain 022 are arranged at both inner ends of the water tank 012. One driving roller 023 is connected to the power machine 021 at the bottom. The arrangement of the driving rollers 023 at both ends can effectively maintain the tension of the conveying chain 022 and prevent the conveying chain 022 from loosening. This ensures that the sliding table trolley 04 maintains a stable speed and trajectory during movement, improving the stability and consistency of the mixing and conveying processes.

The simple structure makes the maintenance of the power mechanism 02 more convenient.

[0035] Figure 3 The structural schematic diagram of the sliding table trolley according to a specific embodiment of the utility model is shown, as Figures 1-3 As shown, the sliding table trolley 04 is clamped on the outer side of the conveying chain 022 through a chain joint 041. The chain joint 041 is fixed to the base 042 of the sliding table trolley 04 by bolts. And stoppers 043 and guiding wheels 044 are respectively arranged on one side of the base 042 close to and away from the conveying chain 022. The sliding table trolley 04 is clamped on the outer side of the conveying chain 022 through the chain joint 041, which simplifies the installation and disassembly process. This not only improves the flexibility of the system but also makes the maintenance and replacement of the sliding table trolley 04 more convenient, reducing production downtime. The settings of the stoppers 043 and guiding wheels 044 can effectively limit the movement range of the sliding table trolley 04 and prevent it from shifting or swinging during transportation, thereby improving the stability and accuracy of the transportation process.

[0036] In a specific embodiment, support columns 045 extend upward from the end points of the upper surface of the base 042. A tray 046 for placing fireworks is detachably provided above the support columns 045. The support columns 045 provide additional structural support. When the tray 046 is detachable, the stability of the tray 046 when carrying fireworks 06 is ensured, and the inclination or movement of the tray 046 caused by external forces or vibrations is avoided, thereby improving the stability of the placement of the fireworks 06. The tray 046 can be quickly detached for separate treatment, thus reducing the cleaning difficulty and time and improving the maintenance efficiency.

[0037] In a specific embodiment, a firework cake edge guard 07 adapted to the size of the fireworks 06 is provided on the upper surface of the tray 046 on the side close to the conveying chain 022. The firework cake edge guard 07 includes a fixing plate 071 fixed to the upper surface of the tray 046 by bolts, and a plurality of raised baffle plates 072 adapted to the shape of the fireworks 06. The firework cake edge guard 07 can effectively prevent the fireworks 06 from sliding or displacing due to vibration or inclination during the conveying process, ensure the stability of the fireworks 06 on the tray 046, reduce the occurrence of accidents, and help accurately position the fireworks 06 on the tray 046. Especially when the fireworks 06 are moved by the conveying chain 022, the firework cake edge guard 07 not only prevents the fireworks 06 from sliding but also plays a protective role, reducing the damage to the fireworks 06 caused by friction or collision and ensuring the integrity of the fireworks 06.

[0038] In a specific embodiment, a firework fixing bracket 047 is provided on the side of the upper surface of the tray 046 perpendicular to the movement direction of the conveying chain 022. A raised fixing spring piece 048 is provided inside the firework fixing bracket 047. The combination of the firework fixing bracket 047 and the raised fixing spring piece 048 inside can more firmly fix the fireworks 06 and prevent them from shifting or inclining due to vibration or external forces during the conveying process. The fixing spring piece 048 provides additional gripping force. Since the sliding table trolley 04 moves in a uniform circular motion during operation and generates centrifugal force, it can prevent the fireworks 06 from being thrown out by the centrifugal force, further enhancing the fixing effect of the fireworks 06.

[0039] In a specific embodiment, the medicine mixing mechanism 03 includes a fixed seat 031 disposed outside the water tank 012. The upper part of the fixed seat 031 extends upward above the water tank 012 and is provided with a medicine mixing device 032. The medicine mixing device 032 has a size adapted to the sliding table trolley 04. The medicine mixing device 032 is installed on the fixed seat 031 outside the water tank 012 and extends upward above the water tank 012, making the space occupied by the entire device more compact and reasonable. This design makes full use of the space above the water tank 012, saves the space within the working area, and is suitable for environments with limited production sites. The operator can set the corresponding fixed seat 031 and medicine mixing device 032 according to the actual number of medicine mixing processes and the site conditions, enabling the equipment to be flexibly applied to different production scenarios. Whether dealing with medicines of different specifications or facing different production requirements, this design can provide sufficient flexibility.

The clamping portion 033 can firmly fix the tray 046 on the upper part of the sliding table trolley 04, and at the same time clamp the tray 046 upward to make it closely cooperate with the medicine mixing device 032, and keep it stable during the medicine mixing process, preventing uneven medicine mixing caused by vibration or external force, which helps to ensure the accuracy and consistency of the medicine mixing process.

[0041] In this application, the gun cake 06 is pushed onto the tray 046 of the sliding table trolley 04 at the preset A station, and the gun cake 06 will be fixed by the gun cake fixing bracket 047 of the sliding table trolley 046; the power machine 021 drives the conveyor chain 022 to work through the driving roller 023, and the sliding table trolley 04 makes a uniform circular motion along with the conveyor chain 022. When the sliding table trolley 04 moves below the medicine mixing device 032, the induction switch 05 senses that the sliding table trolley 04 is in place, and the power machine 021 receives the signal from the induction switch 05 and stops moving; the clamping portion 033 of the medicine mixing device 032 clamps and firmly fixes the tray 046 on the medicine mixing device 032, separating the tray 046 from the sliding table trolley 04. The medicine mixing device 032 performs the medicine mixing process action to fully mix the medicine powder in the gun cake 06 evenly; after the medicine mixing is completed, the clamping portion 033 puts down the tray 046 to re-cooperate with the sliding table trolley 04, and the power machine 021 starts to drive the sliding table trolley 04 to move to the position of the next medicine mixing device 032 for the next medicine mixing process, and so on to complete all the medicine mixing process actions; after all the medicine mixing process actions are completed, the sliding table trolley 04 moves to the preset B station and pushes the gun cake 06 out of the tray 046, and the sliding table trolley 04 enters the preset A station again to start the next cycle.

[0042] The above solution can automate the entire medicine mixing process, reduce manual intervention, improve production efficiency and consistency. Through the induction switch and the clamping part, it ensures the precise positioning of the sliding table trolley and the tray in each process, enabling the powder to be evenly mixed in each medicine mixing process, guaranteeing the quality and stability of the final product. The design of the water tank enables the powder and other impurities generated during the medicine mixing process to fall into the water tank, isolating the flammable drugs with water and preventing the drugs from spontaneously catching fire or exploding.

[0043] This application mainly solves the problems in the prior art that during the automated medicine mixing process, fire and explosion are easily caused due to the accumulation of static electricity, and equipment or program failures are likely to occur in the complex automated structure. This application proposes a medicine mixing and conveying chain device for the inner barrel loading production line of fireworks. The design of the water tank 012 effectively isolates the flammable drugs, ensuring production safety; the automated medicine mixing process reduces manual intervention, improves production efficiency and consistency; the precise positioning of the induction switch 05 and the clamping part 033 guarantees the even mixing of the powder in each medicine mixing process, improving the quality and stability of the final product. The compact layout of the conveying chain 022 and the sliding table trolley 04 not only saves space but also simplifies maintenance, meeting different production requirements, thus significantly improving the efficiency and reliability of the entire production line.
