[0002] The filling of the fireworks inner tube is a key step in the production process. The amount of explosives directly affects the fireworks' performance and safety. To improve efficiency, existing technologies use machinery to automate the filling process. Typically, a solenoid valve is installed at the discharge port of the explosive tank. By setting the opening time of the solenoid valve, a certain amount of explosives is discharged, thus achieving quantitative filling.

[0003] However, while the opening time of the solenoid valve can be kept consistent, the discharge speed of the drug through the outlet is easily affected by various factors, such as the amount of drug remaining or blockage of the outlet. This results in the drug discharge speed not being able to be guaranteed to be the same, making it difficult to ensure the accuracy of the final drug loading.

[0004] Therefore, how to provide a quantitative propellant supply device for the inner tube of fireworks to supply propellant in a quantitative manner has become an urgent technical problem to be solved. Utility Model Content

[0030] The technical solutions of some embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0032] This embodiment discloses a metering device for supplying propellant to the inner tube of a firework, such as... Figures 1-6As shown, it includes:

[0033] The dispensing mechanism 3 includes a supporting base plate 31 and a dispensing base plate 32. The supporting base plate 31 and the dispensing base plate 32 are connected by a fixing plate 311 to form a preset installation gap between the supporting base plate 31 and the dispensing base plate 32. A third cylinder 33 is provided inside the installation gap. A baffle 35 is provided at the output end of the third cylinder 33. A metering plate 34 is provided inside the dispensing base plate 32. A guide plate 36 is provided on the top of the supporting base plate 31. The metering plate 34, the baffle 35 and the guide plate 36 are stacked in sequence and have coaxial plate holes.

[0034] When the third cylinder 33 drives the baffle 35 to move to the first position, the plate holes of the metering plate 34, the baffle 35 and the guide plate 36 are coaxial and form a connection.

[0035] When the third cylinder 33 drives the baffle 35 to move to the second position, the baffle 35 forms a shield for the plate hole of the metering plate 34.

[0036] It should be noted that the dispensing base plate 32 has an installation groove in the middle, and the installation grooves are all the same size. The metering plate 34 has multiple metering plates 34 with different specifications that match the installation grooves. The plate holes of the multiple metering plates 34 with different specifications can store different amounts of fireworks powder, which can correspond to different fireworks inner tubes and different metering plates 34 can be replaced.

[0037] It should be noted that the holes in the metering plate 34 correspond to the number of inner tubes to be filled in the fireworks inner tube, and the arrangement is consistent. First, the baffle 35 blocks the bottom of the holes in the metering plate 34. After the fireworks powder enters the holes in the metering plate 34 from the top and completes the filling of the holes, the position of the baffle 35 is changed so that the fireworks powder passes through the baffle 35 and the guide plate 36 and finally enters the inner tube.

[0038] A fixed amount of fireworks powder is filled through the holes of the metering plate 34, and then, with the cooperation of the baffle 35 and the guide plate 36, the metered amount of fireworks powder finally enters the inner cylinder of the fireworks, completing the metered filling.

[0039] like Figure 4 As shown, the aperture diameters of the metering plate 34 and the baffle 35 are the same, the aperture diameter of the guide plate 36 is larger than that of the metering plate 34 and the baffle 35, and the aperture of the guide plate 36 is set as a stepped flared structure.

[0040] It should be noted that the thickness of the baffle 35 is lower than that of the metering plate 34. After the fireworks powder passes through the plate hole of the baffle 35, it enters the inner cylinder of the fireworks with the help of the guide plate 36 which is provided with the flared plate hole.

[0041] like Figure 4 and Figure 5As shown, the support base plate 31 has support bars 312 on both sides for supporting the guide plate 36, and positioning blocks 313 at both ends for limiting the movement of the baffle 35.

[0042] It should be noted that the positioning strip 312 has an "L" shaped cross section, which is used to support and limit the guide plate 36. The positioning blocks 313 are set in pairs to limit the movement of the baffle 35.

[0043] like Figure 4 and Figure 5 As shown, the top of the dispensing base plate 32 is provided with a baffle 321, and the bottom of the dispensing base plate 32 is provided with a cylinder mounting seat 331 for installing the third cylinder 33. The connector 332 of the third cylinder 33 is embedded in the connecting groove 351 of the baffle 35.

[0044] It should be noted that the top of the dispensing base plate 32 includes a vertical barrier and an inclined barrier, which are used to restrict the position of the fireworks powder. The connector 332 of the third cylinder 33 is fixed to the baffle 35, so that the cylinder can directly drive the baffle 35 to move.

[0045] like Figure 1 and Figure 2 As shown, it also includes a lifting mechanism 1, which includes a bracket 11 and a first cylinder 12. The first cylinder 12 is connected to the support base plate 31 through a connecting plate so that the first cylinder 12 can drive the material distribution mechanism 3 to adjust its height.

[0046] like Figure 1 and Figure 3 As shown, it also includes a positioning mechanism 2, which includes a cylinder mounting bracket 21. A second cylinder 22 is provided outside the cylinder mounting bracket 21. A mounting plate 23 is provided at the output end of the second cylinder 22. A positioning clamp 24 is installed outside the mounting plate 23. The positioning clamp 24 is used to clamp the inner tube of the firework.

[0047] like Figure 3 As shown, the clamping end of the positioning clamp 24 is provided with a clamping groove 241, and the clamping groove 241 is designed as a continuous arc-shaped groove structure corresponding to the inner tube of the fireworks.

[0048] It should be noted that a buffer pad can be provided on the outside of the clamping groove 241 of the positioning clamp 24. The clamping groove 341 of the positioning clamp 24 is set according to the outer circumferential contour of the inner tube of the firework. The positioning clamp 24 is symmetrically arranged on both sides of the inner tube of the firework. When the inner tube of the firework moves to the positioning mechanism 2, the second cylinder 22 drives the clamp to approach and clamp the inner tube of the firework to accurately position the inner tube of the firework, so that the position of the inner tube of the firework corresponds to the position of the guide plate 36.

[0049] like Figure 1 and Figure 6As shown, it also includes a stopper mechanism 4, which includes a cylinder bracket 41. A fourth cylinder 42 is provided outside the cylinder bracket 41. The output end of the fourth cylinder 42 is provided with a stopper top plate 43 and a stopper bottom plate 44. The stopper bottom plate 44 has a through positioning groove 441, and a support column 45 is provided inside the positioning groove 441.

[0050] like Figure 6 As shown, the top plate 43 and the bottom plate 44 of the insert are fixedly connected by fixing bolts, and the positioning groove 441 is a stepped groove.

[0051] like Figure 6 As shown, the tail end of the support column 45 is provided with a pressure pad 451, and the plugging mechanism 4 is used to prevent the plate holes of the metering plate 34 from being blocked.

[0052] It should be noted that the stopper mechanism 4 is provided with several support columns 45 corresponding to the plate hole of the metering plate 34. When the plate hole of the metering plate 34 is blocked, the fourth cylinder 42 can drive the support column 45 to be inserted into the plate hole of the metering plate 34, pushing the firework powder out of the plate hole and causing it to finally fall into the inner tube of the firework.

[0053] Working principle: The positioning mechanism 2 clamps the inner tube of the fireworks to accurately position it. Then, the dispensing mechanism 3 quantitatively introduces the fireworks powder into the plate hole of the dispensing plate 34. After the powder is filled, the powder is quantitatively supplied into the inner tube of the fireworks. The plugging mechanism 4 can push the powder inside the plate hole into the inner tube of the fireworks when the dispensing mechanism 3 is blocked, thus completing the quantitative filling of the fireworks powder inside the inner tube of the fireworks.

[0054] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
