Description

Technical Field

[0001] This utility model relates to the field of fireworks and firecrackers production technology, and in particular to a loading device for fireworks and firecrackers production. Background Technology

[0002] Fireworks and firecrackers production refers to the process of processing raw materials such as gunpowder, oxidizer, combustibles, and binders into fireworks or firecrackers with flammability through a series of technological processes. Among them, the loading equipment for fireworks and firecrackers production is a special mechanical equipment used to accurately fill the inside of the fireworks tube or firecracker paper tube with gunpowder or pyrotechnic powder and control parameters such as the amount of gunpowder and the degree of compaction.

[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: Because the existing fireworks and firecrackers production equipment lacks a limiting device for the firecracker tube, the firecracker tube is prone to lateral displacement on the conveyor belt due to inertia, vibration or human placement error, resulting in misalignment between the discharge port and the center line of the firecracker tube. If the lateral displacement is too large during high-speed conveying or loading, the firecracker tube may tip over due to the shift in the center of gravity, and the explosive may spill. Summary of the Invention

[0004] The technical problem to be solved by this utility model is that the existing fireworks and firecrackers production charging equipment lacks a limiting device for the firecracker tube. Therefore, we propose a fireworks and firecrackers production charging equipment.

[0005] To achieve the above objectives, this application adopts the following technical solution: a loading device for fireworks and firecrackers production, comprising a loading device body, a material cylinder installed on the top of the loading device body, a conveying device installed inside the loading device body, adjustment grooves opened on both sides of the loading device body, an adjustment rod slidably connected inside the adjustment groove, a limit plate installed at one end of the adjustment rod, two structural grooves opened on both sides of the loading device body, the structural grooves being distributed at both ends of the adjustment rod, a round rod fixedly connected inside the structural groove, an irregularly shaped locking block fixedly connected to the surface of the round rod, and several limit grooves opened at both ends of the adjustment rod, the surface of the irregularly shaped locking block being slidably connected to the inside of the limit groove.

[0006] Preferably, each of the limiting plates is equipped with a roller at its bottom, and the surface of the roller is rotatably connected to the top of the material cylinder.

[0007] Preferably, the top and bottom of the structural groove are provided with sliding grooves, and the top and bottom of the irregularly shaped card block are fixedly connected with sliding blocks, the surface of the sliding blocks being slidably connected to the inside of the sliding groove.

[0008] Preferably, a spring is slidably connected to the surface of the round rod, one end of the spring is fixedly connected to the irregularly shaped block, and the other end of the spring is fixedly connected to the interior of the structural groove.

[0009] Preferably, the end of the adjusting rod near the limiting plate has a threaded groove, and a threaded rod is threadedly connected inside the threaded groove. One end of the limiting plate has a circular groove, and the end of the threaded rod away from the adjusting rod is rotatably connected to the inside of the circular groove.

[0010] Preferably, the top of the adjusting rod is provided with a scale.

[0011] Preferably, the height of the limiting plate is one-third of the gap between the main body of the loading device and the conveying device, and the surface of the limiting plate is polished.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, by pulling the irregularly shaped locking block, one end of the block moves out of the limiting groove. At this time, the position of the adjusting rod can be adjusted according to the size of the firecracker tube, causing the adjusting rod to move the limiting plate. Releasing the pull on the irregularly shaped locking block allows one end to return to the limiting groove, and the adjusting rod is repositioned within the groove. By setting the limiting plate, the position of the firecracker tube can be effectively fixed, ensuring precise alignment between the firecracker tube and the powder outlet. This ensures that the powder can be evenly and stably filled into the designated position inside the firecracker tube. Furthermore, this design significantly reduces the risk of the firecracker tube tipping over during operation, further ensuring operational safety and stability. Attached Figure Description

Detailed Implementation

[0021] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0022] Reference Figures 1-4 As shown, this utility model provides a technical solution: a loading device for fireworks and firecrackers production, including a loading device body 1, a material cylinder 2 installed on the top of the loading device body 1, a conveying device 3 installed inside the loading device body 1, adjustment grooves 4 on both sides of the loading device body 1, an adjustment rod 5 slidably connected inside the adjustment grooves 4, a limit plate 6 installed at one end of the adjustment rod 5, two structural grooves 7 on both sides of the loading device body 1, the structural grooves 7 being distributed at both ends of the adjustment rod 5, a round rod 8 fixedly connected inside the structural grooves 7, a shaped locking block 9 fixedly connected to the surface of the round rod 8, and several limiting grooves 10 on both ends of the adjustment rod 5, the surface of the shaped locking block 9 being slidably connected to the inside of the limiting groove 10. Next, by pulling the irregularly shaped locking block 9, one end of the irregularly shaped locking block 9 is moved out of the limiting groove 10. At this time, the position of the adjusting rod 5 can be adjusted according to the size of the firecracker tube, so that the adjusting rod 5 drives the limiting plate 6 to move. Release the pulling of the irregularly shaped locking block 9, so that one end of the irregularly shaped locking block 9 returns to the inside of the limiting groove 10, and the adjusting rod 5 is re-limited inside the adjusting groove 4. By setting the limiting plate 6, the position of the firecracker tube can be effectively fixed, thereby ensuring that the firecracker tube and the gunpowder outlet are precisely aligned, and ensuring that the gunpowder can be evenly and stably filled into the designated position inside the firecracker tube. At the same time, this setting can also significantly reduce the risk of the firecracker tube tipping over during operation, further ensuring the safety and stability of the operation.

[0023] Reference Figure 5 As shown in this embodiment: rollers 11 are installed at the bottom of the limiting plate 6. The surface of the rollers 11 is rotatably connected to the top of the material cylinder 2. By setting the rollers 11, the movement of the limiting plate 6 can be made smoother, and the friction between the limiting plate 6 and the material cylinder 2 can be reduced.

[0024] Reference Figure 3As shown in this embodiment: the top and bottom of the structural groove 7 are provided with sliding grooves 13, and the top and bottom of the irregularly shaped card block 9 are fixedly connected with sliding blocks 14. The surface of the sliding block 14 is slidably connected to the inside of the sliding groove 13. By making the sliding block 14 slide inside the sliding groove 13, the movement of the irregularly shaped card block 9 can be made more stable, and the movement position of the irregularly shaped card block 9 can be restricted, so that the irregularly shaped card block 9 can accurately enter the inside of the limiting groove 10.

[0025] Reference Figure 3 As shown in this embodiment: a spring 15 is slidably connected to the surface of the round rod 8. One end of the spring 15 is fixedly connected to the irregularly shaped block 9, and the other end of the spring 15 is fixedly connected to the interior of the structural groove 7. By setting the spring 15, the elasticity of the spring 15 abuts against the irregularly shaped block 9, which can restrict the movement of the irregularly shaped block 9 and prevent the irregularly shaped block 9 from being displaced due to external vibration.

[0026] Reference Figure 4 and Figure 5 As shown in this embodiment: the end of the adjusting rod 5 near the limiting plate 6 has a threaded groove 16, and a threaded rod 17 is threadedly connected inside the threaded groove 16. The end of the limiting plate 6 has a circular groove 18. The end of the threaded rod 17 away from the adjusting rod 5 is rotatably connected to the inside of the circular groove 18. By rotating the threaded rod 17, the limiting plate 6 can be disassembled from one end of the adjusting rod 5, which is convenient for the user to maintain the limiting plate 6 later. At the same time, rotating the threaded rod 17 can also finely adjust the position of the limiting plate 6, so that the limiting plate 6 fits the firecracker tube better.

[0027] Reference Figure 4 As shown in this implementation scheme: the top of the adjusting rod 5 is provided with a scale 19. By setting the scale 19, the user can intuitively see the adjustment position of the two adjusting rods 5 without repeated adjustment and measurement.

[0028] Reference Figure 1 and Figure 4 As shown in this embodiment: the height of the limiting plate 6 is one-third of the gap between the main body 1 of the charging equipment and the conveying equipment 3, and the surface of the limiting plate 6 is polished. By setting the height of the limiting plate 6 to one-third of the gap between the conveying equipment 3 and the main body 1 of the charging equipment, the displacement of the firecracker tube is restricted while avoiding obstruction of the upper part of the tube, which facilitates subsequent charging operations; at the same time, the surface polishing treatment of the limiting plate 6 can reduce the adhesion of drug dust.

[0029] Working principle: By pulling the irregularly shaped locking block 9, one end of the irregularly shaped locking block 9 is moved out of the limiting groove 10. At this time, the position of the adjusting rod 5 can be adjusted according to the size of the firecracker tube, so that the adjusting rod 5 drives the limiting plate 6 to move. Releasing the pull on the irregularly shaped locking block 9 allows one end of the irregularly shaped locking block 9 to return to the limiting groove 10, so that the adjusting rod 5 is again limited inside the adjusting groove 4. By setting the limiting plate 6, the position of the firecracker tube can be effectively fixed, thereby ensuring precise alignment between the firecracker tube and the outlet, and ensuring that the powder can be filled evenly and stably into the designated position inside the firecracker tube. At the same time, this setting can also significantly reduce the risk of the firecracker tube tipping over during operation, further ensuring the safety and stability of operation. The roller 11 makes the movement of the limiting plate 6 smoother and reduces the friction between the limiting plate 6 and the material tube 2. By allowing the sliding block 14 to slide inside the sliding groove 13, the movement of the irregularly shaped locking block 9 can be further... To enhance stability and limit the movement of the irregularly shaped locking block 9, it ensures that the block 9 accurately enters the limiting groove 10. A spring 15, with its elasticity, abuts against the block 9, restricting its movement and preventing displacement due to external vibrations. Rotating the threaded rod 17 allows the limiting plate 6 to be disassembled from one end of the adjusting rod 5, facilitating future maintenance. Rotating the threaded rod 17 also allows for fine-tuning of the limiting plate 6's position, ensuring a closer fit between the limiting plate 6 and the firecracker tube. The scale 19 allows users to visually observe the adjustment positions of the two adjusting rods 5, eliminating the need for repeated adjustments and measurements. Setting the height of the limiting plate 6 to one-third of the gap between the conveying device 3 and the main body 1 of the loading device restricts the firecracker tube's displacement while preventing obstruction of the upper part of the tube, facilitating subsequent loading operations. Furthermore, the polished surface of the limiting plate 6 reduces the adhesion of drug dust.

[0030] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
