Description

Technical Field

[0001] This utility model relates to the field of fireworks manufacturing technology, specifically a fireworks powder pressing device. Background Technology

[0002] Fireworks are products that use the combustion of various metal powders to create dazzling colors and are widely used in various celebrations and festivals. To achieve the projectile function of the internal firework shells, a fixed amount of propellant needs to be filled into the paper tube as the power source for propulsion. To achieve mass production of fireworks, automated pressing equipment is required for the filling process. Because the propellant, paper tube, and press head form a closed space during pressing, if the pressure value of the press head exceeds the standard, it can easily cause an explosion, especially for unpassivated flames. Furthermore, the closed space of the pressing operation can exacerbate the destructive force of the explosion and the chain reaction affecting surrounding products, endangering personal safety and property.

[0003] Existing patent CN216348100U discloses an explosion-proof device for pressing and molding fireworks powder. The device includes a narrow tube at the upper end of a support frame, which connects to a wider tube with a larger diameter. Multiple spring plates are installed inside the wider tube, and multiple bosses are located on the inner wall of the narrow tube. A pressure plate rests on these bosses, and a pressure column is installed at its lower end. An electric cylinder is mounted on a base, and a push plate is mounted on its output shaft. This invention can precisely control the pressing pressure, ensuring the safe implementation of fireworks pressing operations.

[0004] However, the explosion-proof device still has some defects. During use, the pushing force of the electric cylinder is not easy to control. When the force is too great, the pressure column will detach and enter the wide tube, which will affect the use of the equipment. Furthermore, when the container explodes, the narrow tube cannot completely wrap the container, resulting in poor protection.

[0005] Based on this, a fireworks powder column pressing device is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] In one embodiment, such as Figure 1 - Figure 4 As shown, a fireworks powder column pressing device includes a support base 1, a support frame 11 is installed on one side of the support base 1, an electric push rod 12 is installed on the top of the support frame 11, a pressure sensor 13 is installed at the output end of the electric push rod 12, and a pressure rod 14 is installed at the bottom of the pressure sensor 13.

[0030] The support base 1 is equipped with explosion-proof components;

[0031] A sliding assembly is installed on the outer side of the output end of the electric actuator 12. The sliding assembly includes a connecting ring 3. The connecting ring 3 is installed on the outer side of the output end of the electric actuator 12. A support tube 31 is installed on the outer side of the connecting ring 3. Four sliding grooves 32 are opened around the support tube 31.

[0032] The sliding groove 32 is internally connected with a protective component.

[0033] In this embodiment, the electric actuator 12 is supported by the support frame 11. The operation of the electric actuator 12 pushes the sliding component and the pressure sensor 13 to move downward. The pressure sensor 13 detects the pressure. When the pressure reaches a specified value, the electric actuator 12 is controlled to retract. The protective component slides on the outside of the support tube 31 through the sliding grooves 32 around the support tube 31.

[0034] In one embodiment, such as Figure 1 and Figure 2 As shown, a support plate 15 is installed on the other side of the support frame 11, and a support ring 16 is installed on the outer top of the support frame 11. The support plate 15 provides protection, and the support ring 16 cooperates with the explosion-proof cover 35 to improve the protection effect.

[0035] In one embodiment, such as Figure 1 and Figure 2 As shown, a support component is installed at the top center of the support base 1, and the container 19 is placed through the support component.

[0036] In one embodiment, such as Figure 1 and Figure 2 As shown, the support assembly includes a support rod 17, which is installed at the top center of the support base 1. A placement block 18 is installed at the center of the support rod 17, and a container 19 is placed on top of the placement block 18. The support rod 17 supports the placement block 18, and the placement block 18 allows the container 19 to be placed on top of it.

[0037] In one embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the explosion-proof component includes an explosion-proof barrel 2, which is installed inside the support base 1. Four support columns 21 are installed around the inside of the explosion-proof barrel 2. A rubber block 22 is installed on the top of the support column 21. The support column 21 supports the rubber block 22, the rubber block 22 supports and buffers the buffer component, and the explosion-proof barrel 2 protects against shock waves.

[0038] In one embodiment, such as Figure 1 and Figure 3 As shown, a buffer assembly is installed in the middle of the interior of the explosion-proof barrel 2 to buffer the shock wave.

[0039] In one embodiment, such as Figure 1 and Figure 3As shown, the buffer assembly includes a shock absorber 23, which is installed in the middle of the interior of the explosion-proof barrel 2. A connecting plate 24 is installed on the top of the shock absorber 23, and a fireproof rubber plate 25 is installed on the top of the connecting plate 24. The fireproof rubber plate 25 provides a buffering effect. The shock absorber 23 adopts a spring-type shock absorption, which achieves a buffering and shock absorption effect through the contraction of the spring in conjunction with the contraction of the internal damper.

[0040] In one embodiment, such as Figure 1 and Figure 4 As shown, the protective component includes a sliding block 33, which is slidably connected inside the sliding groove 32. A sleeve 34 is installed on one side of the sliding block 33, and the sleeve 34 is slidably connected to the outside of the support tube 31. An explosion-proof cover 35 is installed at the bottom of the sleeve 34, which provides protection. The sleeve 34 slides on the outside of the support tube 31 to facilitate the up-and-down movement of the explosion-proof cover 35.

[0041] The above embodiment discloses a fireworks powder column pressing device, wherein a container 19 is placed on top of a placement block 18, the placement block 18 is supported by a support rod 17, and an electric push rod 12 is supported by a support frame 11. The operation of the electric push rod 12 pushes the pressure sensor 13 and the buffer assembly to move downwards. The pressure sensor 13 detects the pressure, and when the pressure reaches a certain value, it controls the electric push rod 12 to retract, thereby avoiding the problem of excessive downward pressure causing the gunpowder to explode, improving the explosion-proof effect of the device. The downward movement of the sliding assembly causes the explosion-proof cover 35 to move downwards, which, together with the support ring 16, wraps and protects the outside of the container 19 before the pressing rod 14 enters the container 19, preventing the container 19 from exploding. The explosion-proof cover 35 did not completely cover the explosion during an explosion, which could lead to a dangerous situation. By sliding the sliding block 33 upward inside the sliding groove 32 and cooperating with the sleeve 34 sliding on the outer layer of the support tube 31, the pressure rod 14 can continue to move downward to suppress the explosion, improving the practicality and explosion-proof effect of the device. When an explosion occurs, the explosion-proof cover 35 protects against the explosion. The shock wave enters the interior of the explosion-proof barrel 2 and pushes the fireproof rubber plate 25, which has a certain buffering effect. The contraction of the shock absorber 23 at the bottom of the connecting plate 24 also has a buffering effect. The rubber block 22 at the top of the support column 21 supports and buffers the bottom of the connecting plate 24, which facilitates the buffering of the shock wave and improves the explosion-proof effect and practicality of the device.

[0042] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
