Description

Technical Field

[0001] This utility model belongs to the technical field of fireworks processing equipment, specifically relating to a fully automatic machine for loading propellant inner tubes. Background Technology

[0002] The fully automatic propellant loading and inner tube filling machine is used to automatically fill the inner tube of fireworks with propellants and other agents, and can complete related subsequent processes. It can effectively improve production efficiency, ensure the quality of the filling, and enhance production safety. The propellant tube is transported to the designated position by the conveying mechanism, and the filling mechanism accurately fills the propellant and other agents into the propellant tube through devices such as the propellant metering hole. After filling, the agent is evenly mixed and compacted in the propellant tube by the vibration mixing mechanism. Finally, the sealing mechanism seals the filled propellant tube.

[0003] Currently, fully automatic propellant cartridge loading machines on the market transport cartridges from their starting position to the designated loading station via a conveying device. However, in actual operation, since the cartridges are not fixedly mounted on the conveying device, they may be affected by various external factors during transport. For example, vibrations generated during equipment operation or slight tilting of the conveying device itself may cause the cartridges to shift in position during transport. This shift directly affects the accuracy of the cartridges reaching the loading station, thereby affecting the accurate loading of the propellant and reducing the quality of loading and production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a fully automatic integrated machine for loading and dispensing inner cylinders, which can automatically and precisely adjust the position of the cylinder when it is conveyed to the bottom of the loading station, ensuring that the cylinder accurately reaches the loading station, effectively preventing cylinder deviation, thereby improving the accuracy of loading and production efficiency.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A fully automatic propellant loading and inner cylinder integrated machine includes a conveying device. A control panel is fixedly installed on one side of the conveying device. Multiple propellant cylinders are placed on the top of the conveying device. Multiple sliding rods are fixedly connected to the top of the propellant cylinders. A propellant feeding hopper is slidably connected to the surface of the multiple sliding rods and located at the top of the propellant cylinders. A centering component and a vibration component are provided at the bottom of the propellant feeding hopper.

[0007] Preferably, the alignment component includes a rectangular slide plate fixedly connected to the bottom of the delivery hopper. The four ends of the rectangular slide plate are slidably connected to the surfaces of multiple slide rods. Rectangular grooves are formed around the perimeter of the rectangular slide plate near the bottom of the delivery hopper. A rack is slidably connected to one side of each rectangular groove. An L-shaped gear plate is rotatably connected in each rectangular groove, and the top of the L-shaped gear plate meshes with one side of the rack. An annular rectangular plate is fixedly connected to the top of the multiple racks and fits onto the surface of the bottom of the delivery hopper. A first electric push rod is fixedly installed at the bottom of the top of the delivery hopper, and the piston rod of the first electric push rod is fixedly connected to the annular rectangular plate. A second electric push rod is fixedly installed on one side of the top of the slide rod, and the piston rod of the second electric push rod is fixedly connected to the rectangular slide plate.

[0008] Preferably, the vibration assembly includes multiple cylindrical cam rods rotatably connected to the bottom of the conveying device near the rectangular slide plate, multiple rotating wheels are rotatably connected to one side of the conveying device and one end of the rotating wheels is fixedly connected to the cylindrical cam rods, a belt is rotatably connected to the surface of every two rotating wheels, and a motor is fixedly installed on one side of the conveying device and the output end of the motor is fixedly connected to the rotating wheels.

[0009] Preferably, a plurality of funnels are fixedly connected to the opening at the bottom of the rectangular slide plate, and a spring is fitted on the surface of each funnel, with the top of each spring fixedly connected to the rectangular slide plate.

[0010] Preferably, the bottom of the rectangular slide is fixedly connected to a rectangular frame, and the rectangular frame is fitted onto the surface of the funnel, wherein the inner diameter of the rectangular frame is greater than the width of the cartridge.

[0011] Preferably, a round rod is fixedly connected to the top of the rectangular slide plate near the annular rectangular plate, and a round hole is opened on the surface of the annular rectangular plate and the round hole is slidably connected to the surface of the round rod.

[0012] The technical effects achieved by this utility model are as follows:

[0013] This utility model discloses a fully automatic propellant loading and inner cylinder integrated machine. By incorporating an alignment component and a vibration component, the propellant cartridge is conveyed to the bottom of a rectangular slide plate via a conveying device. Then, the control panel drives a second electric push rod to push the propellant hopper and the rectangular slide plate closer to the top of the propellant cartridge. Subsequently, the first electric push rod pulls an annular rectangular plate upwards, causing multiple racks at the bottom of the annular rectangular plate to move upwards within rectangular grooves. Due to the upward movement of the racks and their meshing with L-shaped gear plates, the bottoms of the multiple L-shaped gear plates rotate downwards, pushing the propellant cartridge from four sides, aligning the cartridge and aligning it with the bottom of the rectangular slide plate. This effectively avoids loading deviation and allows the propellant in the conveying hopper to smoothly slide into the cartridge. Next, the control panel drives the first electric push rod to move in the opposite direction, pushing the multiple racks downwards, thereby driving the multiple L-shaped gear plates... The wheel plate opens, driving the second electric push rod again to align the rectangular frame at the bottom of the rectangular slide with the top of the cartridge, ensuring the cartridge is accurately embedded in the rectangular frame. This further reduces the possibility of loading deviation and improves the automation and production efficiency of loading. After the cartridge is aligned with the rectangular slide, the motor is driven by the control panel to rotate the rotating wheels. Since multiple rotating wheels are connected by belts, the motor can drive the cylindrical cam rods on one side of multiple rotating wheels to rotate. The narrow end of the cylindrical cam rod generates a periodic impact force on the bottom of the cartridge, which effectively promotes the uniform distribution and tight filling of the propellant within the cartridge. This device can automatically and precisely adjust the position of the cartridge when it is conveyed to the bottom of the loading station, ensuring that the cartridge accurately arrives at the loading station and effectively preventing cartridge deviation, thereby improving the accuracy and production efficiency of loading.

[0020] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0021] like Figure 1 - Figure 4 As shown, a fully automatic propellant loading and inner cylinder integrated machine includes a conveying device 1. A control panel is fixedly installed on one side of the conveying device 1. Multiple propellant cylinders 2 are placed on the top of the conveying device 1. Multiple sliding rods 3 are fixedly connected to the top of the propellant cylinders 2. A propellant feeding hopper 4 is slidably connected to the surface of the multiple sliding rods 3 and located on the top of the propellant cylinders 2. A centering component and a vibration component are provided at the bottom of the propellant feeding hopper 4.

[0022] The control panel controls the operation of the entire device. The conveying device 1 is used for the automatic feeding, positioning, loading, and conveying of the cartridges 2. The control panel integrates various operation buttons and a display screen, allowing operators to easily set and adjust the machine's operating parameters, such as the loading amount and conveying speed, to ensure the accuracy and efficiency of the entire loading process. The conveying device 1 is responsible for conveying the cartridges 2 from their initial position to the loading station at the bottom of the rectangular slide plate 5, and after loading, it conveys them to the next process. The delivery hopper 4 is used to fill the propellant. Through the setting of the alignment component, during the loading process, the delivery hopper 4 ensures that each cartridge 2 is accurately positioned at the loading station through the alignment component at its bottom, avoiding loading deviation. At the same time, the vibration component can slightly vibrate the cartridges 2 to promote the uniform falling of the propellant into the inner cartridge 2, avoiding the accumulation or blockage of the propellant particles and ensuring the consistency of the loading density.

[0023] like Figure 1 and Figure 2 As shown, the alignment assembly includes a rectangular slide plate 5 fixedly connected to the bottom of the medicine delivery hopper 4. The four ends of the rectangular slide plate 5 are slidably connected to the surfaces of multiple slide rods 3. Rectangular grooves 6 are provided around the bottom of the rectangular slide plate 5 near the bottom of the medicine delivery hopper 4. A rack 7 is slidably connected to one side of each rectangular groove 6. An L-shaped gear plate 8 is rotatably connected in each rectangular groove 6, and the top of the L-shaped gear plate 8 is meshed with one side of the rack 7. An annular rectangular plate 9 is fixedly connected to the top of the multiple racks 7, and the annular rectangular plate 9 is fitted onto the bottom surface of the medicine delivery hopper 4. A first electric push rod 10 is fixedly installed at the bottom of the top of the medicine delivery hopper 4, and the piston rod of the first electric push rod 10 is fixedly connected to the annular rectangular plate 9. A second electric push rod 18 is fixedly installed on one side of the top of the slide rod 3, and the piston rod of the second electric push rod 18 is fixedly connected to the rectangular slide plate 5.

[0024] Specifically, the conveying device 1 transports the cartridge 2 to the bottom of the rectangular slide plate 5. The control panel drives the second electric push rod 18 to push the delivery hopper 4 and the rectangular slide plate 5 to the top near the cartridge 2. Then, the control panel drives the first electric push rod 10 to pull the annular rectangular plate 9 upwards, which in turn causes multiple racks 7 at the bottom of the annular rectangular plate 9 to move upwards within the rectangular groove 6. Due to the upward movement of the racks 7 and their meshing with the L-shaped gear plates 8, the bottoms of the L-shaped gear plates 8 rotate downwards, pushing the cartridge 2 from four sides, thus straightening the cartridge 2 and effectively preventing loading deviation. The tight meshing between the top of the L-shaped gear plates 8 and the racks 7 ensures sufficient power. Effective transmission ensures a smooth and powerful push when the bottom side contacts the side of the cartridge 2. After the cartridge 2 is aligned, it aligns with the bottom of the rectangular slide plate 5, allowing the propellant in the delivery hopper 4 to slide smoothly into the cartridge 2, completing the loading process. The control panel drives the first electric push rod 10 to move in the opposite direction, pushing multiple racks 7 downwards, which in turn drives multiple L-shaped gear plates 8 to open. The second electric push rod 18 then pushes the bottom of the rectangular slide plate 5 closer to the top of the cartridge 2, reducing the possibility of loading deviation, improving the automation level and production efficiency of loading, significantly reducing manpower input, speeding up loading, increasing the production quantity of fireworks inner tubes, and meeting the needs of large-scale production.

[0025] like Figure 1 and Figure 3 As shown, the vibration assembly includes multiple cylindrical cam rods 11 rotatably connected to the bottom of the conveying device 1 near the rectangular slide plate 5. Multiple rotating wheels 12 are rotatably connected to one side of the conveying device 1, and one end of the rotating wheel 12 is fixedly connected to the cylindrical cam rods 11. A belt 13 is rotatably connected to the surface of every two rotating wheels 12. A motor 14 is fixedly installed on one side of the conveying device 1, and the output end of the motor 14 is fixedly connected to the rotating wheel 12.

[0026] After the cartridge 2 is connected to the rectangular slide plate 5 at the bottom of the propellant hopper 4, the motor 14 is driven by the control panel, which in turn drives the rotating wheel 12 to rotate. Since the multiple rotating wheels 12 are connected by belts 13, the motor 14 can drive the cylindrical cam rod 11 on one side of the multiple rotating wheels 12 to rotate. The cylindrical cam rod 11 adopts a cam-shaped structure design that is wider at the top and narrower at the bottom. When it rotates, the cam-shaped structure causes the narrow end of the cylindrical cam rod 11 to generate a periodic impact force on the bottom of the cartridge 2. The impact force is transmitted through the cartridge 2 to the propellant filled inside, which effectively promotes the uniform distribution and tight filling of the propellant, thereby improving the propellant loading quality and firing performance of the cartridge 2. It can ensure that the amount of propellant in each inner tube is consistent. At the same time, the design of the vibration component can make the propellant distribution more uniform and dense, reduce the poor fireworks display effect or safety problems caused by uneven loading, and improve the overall quality of fireworks products.

[0027] like Figure 4 As shown, multiple funnels 15 are fixedly connected to the opening at the bottom of the rectangular slide plate 5. Each funnel 15 is fitted with a spring 16 on its surface, and the top of each spring 16 is fixedly connected to the rectangular slide plate 5.

[0028] Specifically, the funnel 15 connects the rectangular slide plate 5 to the top of the cartridge 2. The funnel 15 has a structure that is wider at the top and narrower at the bottom, which facilitates the continuous and stable flow of propellant into the rectangular slide plate 5. It also effectively prevents the propellant from clogging during the transport process, improving the efficiency and stability of the loading process. The design of the spring 16 provides a buffer at the bottom of the cartridge 2 and the rectangular slide plate 5, allowing the cartridge 2 to move more smoothly when it moves upward through the vibration component. This prevents the funnel 15 from shifting or tilting due to vibration, further ensuring the accuracy and safety of the loading process. The elastic restoring force of the spring 16 also helps the cartridge 2 to quickly and stably return to its initial position when it descends and resets. Overall, this improves the automation level and operating efficiency of the fully automatic propellant loading machine, reduces the number of manual contact points with the propellant, lowers the risk of safety accidents caused by human error, and ensures the safety of the production process.

[0029] like Figure 4 As shown, a rectangular frame 17 is fixedly connected to the bottom of the rectangular slide plate 5 and the rectangular frame 17 is fitted onto the surface of the funnel 15. The inner diameter of the rectangular frame 17 is greater than the width of the cartridge 2.

[0030] The bottom of the rectangular slide plate 5 is provided with a rectangular frame 17 that is compatible with the cartridge 2, ensuring that the cartridge 2 can be accurately embedded in the rectangular frame 17, further reducing the possibility of loading deviation; the insertion design of the rectangular frame 17 and the cartridge 2 makes it easy to limit the top of the cartridge 2, so that the cartridge 2 will not shift when vibrating.

[0031] like Figure 1 and Figure 2 As shown, a round rod 19 is fixedly connected to the top of the rectangular slide plate 5 near the top of the annular rectangular plate 9. A round hole 20 is opened on the surface of the annular rectangular plate 9 and the round hole 20 is slidably connected to the surface of the round rod 19.

[0032] Specifically, the annular rectangular plate 9 is slidably connected to the round rod 19 to limit the position of the annular rectangular plate 9, so that the annular rectangular plate 9 can drive the rack 7 to move smoothly up and down in the rectangular groove 6.

[0033] The working principle of this utility model is as follows: First, the cartridge 2 is conveyed to the bottom of the rectangular slide plate 5 through the conveying device 1. The second electric push rod 18 is driven by the control panel to push the delivery hopper 4 and the rectangular slide plate 5 closer to the top of the cartridge 2. Then, the first electric push rod 10 is driven to pull the annular rectangular plate 9 upward, causing multiple racks 7 at the bottom of the annular rectangular plate 9 to move upward in the rectangular groove 6. Because the racks 7 are meshed with the L-shaped gear plates 8, the bottom of the multiple L-shaped gear plates 8 rotates downward and pushes the cartridge 2 from all four sides to align it with the bottom of the rectangular slide plate 5. When the cartridge 2 is aligned and aligned with the bottom of the rectangular slide plate 5... The rectangular frame 17 of the part is aligned to ensure that the cartridge 2 is accurately embedded in the rectangular frame 17; then the first electric push rod 10 is driven to move in the opposite direction, pushing multiple racks 7 to move down and causing multiple L-shaped gear plates 8 to open. Then the second electric push rod 18 is driven to push the funnel 15 to be inserted into the top of the cartridge 2. Next, the drive motor 14 drives the rotating wheel 12 to rotate. Multiple rotating wheels 12 are connected by a belt 13, which in turn drives the motor 14 to drive the cylindrical cam rod 11 to rotate. The cylindrical cam rod 11 is cam-shaped with a wider top and a narrower bottom. When it rotates, the narrow end vibrates the bottom of the cartridge 2, thereby completing the filling operation of the cartridge 2.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
