Description

TECHNICAL FIELD

[0001] The present application relates to the field of firework production equipment, and in particular to a firework inner tube filling production line mixed medicine conveying chain device and conveying method. BACKGROUND

[0002] Traditional firework inner tube filling is basically made by hand, and the mixed medicine work is basically manually operated, which has low production efficiency, high labor intensity, high cost, high risk, and is an inevitable trend of development of mechanization, automation and intelligentization.

[0003] With the development of automation, the mixed medicine of firework inner tube filling begins to be carried out in an automated manner. However, due to the friction during the mixing and transmission of gunpowder, static electricity may be generated, especially in a dry environment. If this static electricity accumulation is not effectively released, it may cause sparks, leading to accidental explosion or fire. At the same time, the structure of most automatic equipment is relatively complex, although it improves the production efficiency and precision, it also brings new problems, such as equipment failure, sensor failure or program error. These problems may cause the proportion deviation of mixed medicine or inaccurate gunpowder filling, and further affect the performance of the firework. SUMMARY

[0004] In view of the problems that static electricity accumulation easily causes fire and explosion in the automatic mixed medicine process, and the complex automatic structure easily causes equipment or program failure, the present application proposes a firework inner tube filling production line mixed medicine conveying chain device and conveying method to solve the above problems.

[0005] According to the first aspect of the present application, a firework inner tube filling production line mixed medicine conveying chain device is provided, which comprises a water tank mechanism and a power mechanism. The water tank mechanism comprises a rack and a water tank fixed above the rack. The power mechanism comprises a power machine and a conveying chain arranged below and above the water tank respectively. A plurality of sliding platform trolleys are detachably installed on the conveying chain. The power machine drives the conveying chain to drive the sliding platform trolleys to move at a uniform speed in the water tank. The sliding platform trolleys pass through a plurality of mixed medicine mechanisms arranged at equal intervals on the side of the water tank in turn.

[0006] By adopting the above technical solution, water can be injected into the water tank, so that the water surface is slightly higher than the highest surface of the conveying chain. The medicine powder and other impurities generated during the mixing process fall into the water tank, so that the combustible medicine is isolated by water to avoid the natural ignition and explosion of the medicine. The power machine drives the conveying chain to drive the sliding platform trolleys, so that the whole mixed medicine conveying process is automated, reducing manual intervention, improving production efficiency and output, and reducing errors. The conveying chain adopts a compact circular motion mode, so that the equipment occupies a small area, which is conducive to efficient production layout in limited space.

[0007] In some specific embodiments, the conveying chain is arranged in a ring shape parallel to the upper surface of the water tank, and the inner side of the conveying chain is provided with an inductive switch corresponding to the position of the mixing mechanism.

[0008] By using the above technical solution, the position of the sliding trolley is sensed by the inductive switch, and when the sliding trolley moves to the position corresponding to the mixing mechanism, the inductive switch can send a signal to the power machine to stop working, so that the sliding trolley is accurately stopped at the position corresponding to the mixing mechanism, which is beneficial to fully and uniformly mixing the medicine. When a mixing process is completed, the power machine drives the sliding trolley to move to the position of the next mixing mechanism, so that the mixing process can be accurately and correctly performed.

[0009] In some specific embodiments, the water tank is provided with drive rollers at both ends of the inner side for tensioning and driving the conveying chain to move, and the drive roller at one end is connected with the power machine at the bottom.

[0010] By using the above technical solution, the drive rollers arranged at both ends can effectively maintain the tension of the conveying chain, preventing the chain from relaxing, which ensures that the sliding trolley maintains a stable speed and trajectory during movement, improving the stability and consistency of the mixing and conveying process. At the same time, by directly connecting the drive rollers with the power machine, efficient power transmission is achieved, reducing intermediate transmission links, reducing energy loss, and improving the transmission efficiency of the entire system. The simple structure makes it easier to maintain the power mechanism.

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

[0012] By using the above technical solution, the sliding trolley is clamped to the outer side of the conveying chain through a chain joint, simplifying the installation and disassembly process, which not only improves the flexibility of the system, but also makes it easier to maintain and replace the sliding trolley, reducing downtime. The arrangement of the stop block and the directional wheel can effectively limit the movement range of the sliding trolley, preventing it from deviating or swinging during the conveying process, thereby improving the stability and accuracy of the conveying process.

[0013] In some specific embodiments, support columns are upwardly extended at the endpoints of the upper surface of the base, and a tray for placing the flower bombs is detachably arranged above the support columns.

[0014] By using the above technical solution, the support columns provide additional structural support, ensuring the stability of the tray when carrying the flower bombs, and preventing the tray from tilting or moving due to external forces or vibrations, thereby improving the stability of the flower bomb placement. The detachable design of the tray makes it easier to maintain or clean, thereby reducing the difficulty and time of cleaning and improving the maintenance efficiency.

[0015] In some specific embodiments, the upper surface of the tray is provided with a cake blocking edge that is adapted to the size of the cake near the side of the conveying chain.

[0016] By adopting the above technical solution, the cake blocking edge can effectively prevent the cake from sliding or displacing due to vibration or tilting during transportation, ensuring that the cake remains stable on the tray and reducing accidents. The design of the cake blocking edge can help accurately position the cake on the tray, especially when the cake is moved by the conveying chain. The blocking edge not only prevents the cake from sliding, but also provides protection, reducing damage to the cake caused by friction or collision, and ensuring the integrity of the cake.

[0017] In some specific embodiments, the upper surface of the tray is provided with a cake blocking edge that is adapted to the size of the cake near the side of the conveying chain.

[0018] By adopting the above technical solution, the cake blocking edge can effectively prevent the cake from sliding or displacing due to vibration or tilting during transportation, ensuring that the cake remains stable on the tray and reducing accidents. The design of the cake blocking edge can help accurately position the cake on the tray, especially when the cake is moved by the conveying chain. The blocking edge not only prevents the cake from sliding, but also provides protection, reducing damage to the cake caused by friction or collision, and ensuring the integrity of the cake.

[0019] In some specific embodiments, the mixing mechanism includes a fixed seat arranged outside the water tank, and the upper part of the fixed seat extends upwards above the water tank and is provided with a mixing device, and the mixing device has a size adapted to the size of the slide car.

[0020] By adopting the above technical solution, the mixing device is installed on the fixed seat outside the water tank and extends upwards above the water tank, making the space occupied by the entire device more compact and reasonable. This design makes full use of the space above the water tank, saving space in the work area. It is suitable for environments with limited production space. The operator can set the corresponding fixed seat and mixing device according to the actual number of mixing processes and site conditions, so that the equipment can be flexibly applied to different production scenarios. Whether it is handling different specifications of drugs or facing different production needs, this design provides sufficient flexibility.

[0021] In some specific embodiments, the mixing device is also provided with a clamping part corresponding to the position of the upper part of the slide car.

[0022] By adopting the above technical solution, the clamping part can firmly fix the tray on the upper part of the slide car, and at the same time clamp the tray upwards, so that it tightly cooperates with the mixing device, and remains stable during the mixing process, preventing uneven mixing due to vibration or external force, and helping to ensure the accuracy and consistency of the mixing process.

[0026] S3: the clamping part of the mixed medicine device clamps the tray and tightly fixes it on the mixed medicine device, so that the tray is separated from the sliding trolley, the mixed medicine device performs the mixed medicine process action, and the medicine powder in the firecracker is fully mixed and uniform;

[0027] S4: after the mixed medicine process is completed, the clamping part releases the tray to cooperate with the sliding trolley again, the power machine starts to drive the sliding trolley to move to the position of the next mixed medicine device to perform the next mixed medicine process, and the process is repeated to complete all the mixed medicine process actions;

[0028] S5: after completing all the mixed medicine process actions, the sliding trolley moves to the preset B station, and the firecracker is pushed out of the tray, and the sliding trolley enters the preset A station again to start the next cycle.

[0029] By adopting the above technical scheme, the whole mixed medicine process is automatically operated, manual intervention is reduced, production efficiency and consistency are improved, the inductive switch and the clamping part ensure that the sliding trolley and the tray are accurately positioned in each process, so that the medicine powder is uniformly mixed in each mixed medicine process, and the quality and stability of the final product are ensured. The design of the water tank enables the medicine powder and other impurities generated during the mixed medicine process to fall into the water tank, so that the combustible medicine is isolated by water, and the fire and explosion caused by the natural ignition of the medicine are avoided.

The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present application is defined by the appended claims.

[0039] According to a first aspect of the present application, a mixed medicine delivery chain device for a firework inner tube filling production line is provided,Figure 1 A schematic diagram of a mixed medicine conveying chain device structure according to an embodiment of the present application is shown, as shown in the figure, the device comprises a water tank mechanism 01, a power mechanism 02; the water tank mechanism 01 comprises a rack 011 and a water tank 012 fixed above the rack 011; the power mechanism 02 comprises a power machine 021 and a conveying chain 022 arranged below and above the water tank 012 respectively; a plurality of sliding platform trolleys 04 are detachably installed on the conveying chain 022; the power machine 021 drives the conveying chain 022 to drive the sliding platform trolley 04 to move at a uniform speed in a circle in the water tank 012; the sliding platform trolley 04 passes through a plurality of mixed medicine mechanisms 03 arranged at equal intervals on the side of the water tank 012 in turn; 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 medicine powder and other impurities generated during the mixing process fall into the water tank 012, so that the combustible medicine is isolated by water, avoiding the natural ignition of the medicine, explosion; the power machine 021 drives the conveying chain 022 to drive the sliding platform trolley 04, so that the whole mixing and conveying process is automated, reducing manual intervention, improving production efficiency and yield, while reducing errors; the conveying chain 022 adopts a compact circular motion mode, so that the equipment occupies a small area, which is beneficial to realize efficient production layout in limited space, and the specific principle and structure are combined Figures 2-3 The application is described in detail in combination with

[0040] Figure 2 A schematic diagram of a power mechanism installation according to a specific embodiment of the present application is shown, as shown in Figures 1-2 The conveying chain 022 is arranged in a ring parallel to the upper surface of the water tank 012, and the inner side of the conveying chain 022 is provided with an inductive switch 05 corresponding to the position of the mixed medicine mechanism 03; the position of the sliding platform trolley 04 is inducted by using the inductive switch 05, when the sliding platform trolley 04 moves to the position corresponding to the mixed medicine mechanism 03, the inductive switch 05 can send a signal to the power machine 021 to stop working, so that the sliding platform trolley 04 is accurately stopped at the corresponding position of the mixed medicine mechanism 03, which is beneficial to fully and uniformly mix the medicine; when a mixing process is completed, the power machine 021 drives the sliding platform trolley 04 to move to the position of the next mixed medicine mechanism 03, which can ensure that the mixing process is accurately and correctly carried out.

[0041] Further, the mixing mechanism 03 is arranged on one side of the length direction of the water tank 012, and the phenomenon of fire explosion may also be caused due to a large amount of gunpowder floating on the water surface. The water tank 012 is further provided with a water inlet (not shown in the figure) on one side of the width direction, and a water outlet (not shown in the figure) is arranged on the other side opposite to the water inlet. Through the cooperation of the water inlet and the water outlet, the water in the water tank 012 flows, and the gunpowder and other impurities falling into the water tank 012 flow out of the water outlet along with the water flow, so as to avoid the safety hidden danger caused by the accumulation of excessive gunpowder and impurities. In addition, the water tank 012 is further provided with a plurality of water spraying holes (not shown in the figure) arranged on the two sides of the length direction and the side of the water inlet and spraying water to the water outlet. When the impurities cannot naturally flow out of the water outlet along with the water flow, the impurities can be sent to the water outlet by the aid of the water flow sprayed by the water spraying holes. In addition, when a small amount of gunpowder in the water tank 012 is burning, the water flow can quickly extinguish the fire.

[0042] Further, the water tank 012 is further provided with a gunpowder concentration detection device (not shown in the figure) such as an electric conductivity sensor. After the gunpowder is dissolved in water, the electric conductivity of the water changes, so that the concentration of the gunpowder can be indirectly judged through the change of the electric conductivity. When it is detected that the water in the water tank 012 contains gunpowder with a certain concentration, an additional alarm device (not shown in the figure) can remind the staff, and the power mechanism 02 and the mixing mechanism 03 are stopped to avoid more safety hidden dangers.

[0043] In a specific embodiment, the water tank 012 is provided with a driving roller 023 arranged on the inside of the two ends of the water tank 012 and used for tensioning and driving the conveying chain 022 to move. The driving roller 023 at one end is connected with the power machine 021 at the bottom. The driving roller 023 arranged at the two ends can effectively maintain the tension of the conveying chain 022, so as to prevent the conveying chain 022 from relaxing. This ensures that the sliding platform trolley 04 maintains a stable speed and trajectory during movement, and improves the stability and consistency of the mixing and conveying process. In addition, the driving roller 023 is directly connected with the power machine 021, so that the power is efficiently transmitted, the intermediate transmission link is reduced, the energy loss is reduced, the transmission efficiency of the whole system is improved, and the simple structure makes the maintenance of the power mechanism 02 more convenient.

[0044] Figure 3 A structural schematic diagram of the sliding platform trolley according to one specific embodiment of the application is shown in FIG. 1. Figures 1-3As shown, the sliding trolley 04 is clamped on the outside of the conveying chain 022 through the chain joint 041, the chain joint 041 is fixed on the base 042 of the sliding trolley 04 through bolts, and the base 042 is provided with a stop block 043 and a directional wheel 044 below on the side close to and away from the conveying chain 022 respectively. The sliding trolley 04 is clamped on the outside of the conveying chain 022 through the chain joint 041, which simplifies the installation and disassembly process, not only improves the flexibility of the system, but also makes it more convenient to maintain and replace the sliding trolley 04, reduces the production downtime, and the arrangement of the stop block 043 and the directional wheel 044 can effectively limit the movement range of the sliding trolley 04, prevent it from deviating or swinging during the conveying process, and improve the stability and accuracy of the conveying process.

[0045] In specific embodiments, the upper surface of the base 042 extends upward at the endpoints to form support columns 045, and a tray 046 for placing firecrackers is detachably arranged above the support columns 045. The support columns 045 provide additional structural support, and ensure the stability of the tray 046 when carrying firecrackers 06, avoiding tilting or moving of the tray 046 due to external force or vibration, thereby improving the stability of the firecracker 06 placement. The tray 046 can be quickly detached for separate processing, thereby reducing cleaning difficulty and time, and improving maintenance efficiency.

[0046] In specific embodiments, the upper surface of the tray 046 is provided with a cake blocking edge 07 that matches the size of the firecracker 06 on the side close to the conveying chain 022. The cake blocking edge 07 includes a fixed plate 071 fixed on the upper surface of the tray 046 by bolts, and a plurality of raised baffles 072 arranged to match the shape of the firecracker 06. The cake blocking edge 07 can effectively prevent the firecracker 06 from sliding or moving due to vibration or tilting during the conveying process, ensure the stability of the firecracker 06 on the tray 046, and reduce accidents. It can help to accurately position the firecracker 06 on the tray 046, especially when the firecracker 06 is moved by the conveying chain 022. The cake blocking edge 07 not only prevents the firecracker 06 from sliding, but also plays a protective role, reducing damage to the firecracker 06 caused by friction or collision, and ensuring the integrity of the firecracker 06.

[0047] In specific embodiments, the upper surface of the tray 046 is provided with a cake fixing support 047 on the side perpendicular to the movement direction of the conveying chain 022, and the inner side of the cake fixing support 047 is provided with a protruding fixing spring 048. The combination of the cake fixing support 047 and the inner protruding fixing spring 048 can more firmly fix the firecracker 06, prevent it from moving or tilting due to vibration or external force during the conveying process, and provide additional grip through the fixing spring 048. Since the slide trolley 04 moves at a uniform speed during the working process, it will generate a centrifugal force, which can prevent the firecracker 06 from being thrown out by the centrifugal force, further enhancing the fixing effect of the firecracker 06.

[0048] In specific embodiments, the mixing mechanism 03 includes a fixed seat 031 arranged outside the water tank 012, and the upper part of the fixed seat 031 extends above the water tank 012 and is provided with a mixing device 032. The mixing device 032 has a size suitable for the slide trolley 04. The mixing device 032 is installed on the fixed seat 031 outside the water tank 012 and extends above the water tank 012, so that the space occupied by the entire device is more compact and reasonable. This design makes full use of the space above the water tank 012, saving space in the working area. It is suitable for environments with limited production space. The operator can set the corresponding fixed seat 031 and mixing device 032 according to the actual number of mixing procedures and site conditions, so that the equipment can be flexibly applied to different production scenarios. Whether it is dealing with different specifications of medicine or facing different production needs, this design provides sufficient flexibility.

[0049] In some specific embodiments, the mixing device 032 is also provided with a clamping part 033 corresponding to the position of the upper part of the slide trolley 04. The clamping part 033 can firmly fix the tray 046 on the upper part of the slide trolley 04, and clamp the tray 046 upward, so that it tightly cooperates with the mixing device 032, and keeps stable during the mixing process, preventing uneven mixing due to vibration or external force, and helping to ensure the accuracy and consistency of the mixing process.

[0052] S2: The power machine drives the conveying chain to work through the driving roller, and the slide trolley moves at a uniform speed in a circular motion. When the slide trolley moves under the mixing device, the inductive switch senses that the slide trolley is in place, and the power machine stops moving upon receiving the signal from the inductive switch.

[0053] S3: The clamping part of the mixing device clamps the tray and tightly fixes it on the mixing device, separates the tray from the sliding trolley, and the mixing device performs the mixing process to fully mix the powder in the cake;

[0054] S4: After the mixing is completed, the clamping part releases the tray and re-cooperates with the sliding trolley, and the power machine is started to drive the sliding trolley to move to the next mixing device position to perform the next mixing process, and so on to complete all the mixing processes;

[0055] S5: After completing all the mixing processes, the sliding trolley moves to the preset B station and pushes the cake out of the tray, and the sliding trolley enters the preset A station again to start the next cycle.

[0056] The above method can make the whole mixing process run automatically, reduce manual intervention, improve production efficiency and consistency, and through the inductive switch and the clamping part, the sliding trolley and the tray are accurately positioned in each process, so that the powder is uniformly mixed in each mixing process, ensuring the quality and stability of the final product. The design of the water tank allows the powder and other impurities generated during the mixing process to fall into the water tank, so that the combustible drug is isolated by water to avoid spontaneous ignition and explosion of the drug.

[0057] The present application mainly solves the problems of easy ignition and explosion due to static electricity accumulation in the automatic mixing process in the prior art, and the complex automatic structure is prone to equipment or program failure. The present application provides a flower cake inner tube filling production line mixing and conveying chain device and a conveying method, which effectively isolates the combustible drug through the design of the water tank 012 to ensure production safety; the automatic mixing process reduces manual intervention, improves production efficiency and consistency; the accurate positioning of the inductive switch 05 and the clamping part 033 ensures the uniform mixing of the powder in each mixing process, improves the quality and stability of the final product, and the compact layout of the conveying chain 022 and the sliding trolley 04 not only saves space, but also simplifies maintenance, adapts to different production needs, thereby significantly improving the efficiency and reliability of the whole production line.
