The air pump group adjusts the pressure inside the gunpowder canister to facilitate the replenishment or discharge of gunpowder. During the operation of the air pump group, the filter box plays a filtering role. When the air pump group draws external gas into the gunpowder canister, the filter box filters the external gas to reduce the impact of external foreign matter on the quality of the gunpowder. When the air pump group draws gas out of the gunpowder canister, the filter box filters the gunpowder inside the canister to prevent the gunpowder from being discharged from the gunpowder canister with the gas, thus preventing waste.

[0012] 2. The gunpowder weighing device for producing sparkler-type fireworks according to this utility model, when replenishing gunpowder into the gunpowder tank, closes the discharge valve and opens the feed valve, and controls the air pump unit to work to extract the gas from the gunpowder tank.

When discharging gunpowder from the gunpowder tank, open the discharge valve and close the feed valve, and control the air pump unit to work to extract external gas into the gunpowder tank. During this process, the gunpowder in the gunpowder tank is discharged through the discharge pipe. This method can avoid the gunpowder being blocked at the bottom of the inner cavity of the gunpowder tank or in the discharge pipe due to static friction, ensuring effective discharge of gunpowder.

[0013] 3. The gunpowder weighing device for producing sparkling fireworks according to this utility model uses a weighing plate to block and seal the outlet of the collection box, so that the metering is carried out in a sealed environment, reducing the safety hazards caused by gunpowder floating outward, and also reducing gunpowder waste. After the gunpowder falls onto the weighing plate, the weight of the gunpowder is weighed by the weighing sensor, ensuring the quality of fireworks production.

[0014] 4. The gunpowder weighing device for producing sparkler-type fireworks according to this utility model uses a positioning plate to support and limit the movement of the mobile frame. The positioning plate also acts as a guide during the movement of the mobile frame, ensuring its stability. After the weighing component finishes weighing the gunpowder, the telescopic cylinder is controlled to drive the mobile frame to move. When the weighing plate moves away from under the collection box, the discharge port moves to the bottom of the collection box, facilitating the discharge of the weighed gunpowder from the collection box. During the movement of the mobile frame, the gunpowder on the upper part of the symmetrical weighing plate at the bottom of the collection box is cleaned to prevent residual gunpowder on the weighing plate from affecting the weighing accuracy.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a gunpowder weighing device for the production of fireworks that produce sparklers, including a support plate 1, a gunpowder container 3 disposed on the top of the support plate 1, the gunpowder container 3 being used for storing gunpowder, preferably, the bottom of the gunpowder container 3 is conical to facilitate the discharge of gunpowder from inside the gunpowder container 3, a collection box 8 is installed at the bottom of the gunpowder container 3, and a support frame 2 is fixed on the side of the support plate 1 to support and position the collection box 8. The gunpowder container 3 is supported and positioned by the set support frame 2, which facilitates the setting and use of this weighing device.

[0023] The gunpowder container 3 is equipped with a pressure regulating component at its top, which communicates with its inner cavity. A feeding component communicating with its inner cavity is located on the upper side of the gunpowder container 3, and a discharge component communicating with its inner cavity is located on the lower side of the gunpowder container 3. The discharge port of the discharge component is located inside the collection box 8. The pressure regulating component adjusts the internal pressure of the gunpowder container 3 for replenishing or discharging gunpowder. When gunpowder needs to be replenished, the pressure regulating component draws gas from the inside of the gunpowder container 3 to reduce its pressure, making it easier for the gunpowder container 3 to draw gunpowder from the outside through the feeding component. When discharging gunpowder from the gunpowder container 3, the pressure regulating component draws air from the outside into the gunpowder container 3 to increase its internal pressure, making it easier for the gunpowder container 3 to discharge its gunpowder to the outside.

[0024] The pressure adjustment assembly includes an air pump unit 4 installed on top of the gunpowder container 3. A filter box 5 is installed on the top of the inner cavity of the gunpowder container 3. The air pump unit 4 is connected to the inner cavity of the filter box 5. The operation of the air pump unit 4 is controlled to adjust the pressure inside the gunpowder container 3, which facilitates the replenishment or discharge of gunpowder in the gunpowder container 3. During the operation of the air pump unit 4, the filter box 5 plays a filtering role. When the air pump unit 4 draws external gas into the gunpowder container 3, the filter box 5 is used to filter the external gas to reduce the impact of external foreign matter on the quality of gunpowder. When the air pump unit 4 draws gas out of the gunpowder container 3, the filter box 5 filters the gunpowder in the gunpowder container 3 to prevent the gunpowder from being discharged from the gunpowder container 3 with the gas and thus being wasted.

[0025] The feeding assembly includes a feeding pipe 6 installed on the upper side of the gunpowder container 3 and communicating with the inner cavity of the gunpowder container 3. A feeding valve 7 is installed on the feeding pipe 6. The discharging assembly includes a discharging pipe 9 installed at the bottom of the gunpowder container 3 and communicating with its inner cavity. The end of the discharging pipe 9 away from the gunpowder container 3 is connected to the inner cavity of the collection box 8. A discharging valve 10 is installed on the discharging pipe 9. When adding gunpowder to the gunpowder container 3, the discharging valve 10 is closed and the feeding valve 7 is opened, controlling the air pump unit 4 to work and extract the gunpowder from the gunpowder container 3. During the gas discharge process, the gunpowder container 3 draws external gunpowder into its inner cavity through the feed pipe 6 to replenish the gunpowder in the gunpowder container 3. When the gunpowder in the gunpowder container 3 is discharged, the discharge valve 10 is opened and the feed valve 7 is closed. The air pump group 4 is controlled to work to draw external gas into the gunpowder container 3. During this process, the gunpowder in the gunpowder container 3 is discharged through the discharge pipe 9. This method can avoid the gunpowder from being blocked at the bottom of the inner cavity of the gunpowder container 3 or in the discharge pipe 9 due to static friction, and ensure the effective discharge of gunpowder.

[0026] The bottom of the collection box 8 is open, and a movable frame 11 is slidably installed on the lower side of the collection box 8. A weighing component is installed inside the movable frame 11, and a discharge port is opened on the side of the movable frame 11. After the gunpowder is discharged from the discharge component, it is collected in the collection box 8. The weighing component at the bottom of the collection box 8 weighs the gunpowder. After the amount of gunpowder reaches the standard, the discharge component is closed. Then, the movable frame 11 is driven to move the discharge port to directly below the collection box 8, so that the gunpowder can be discharged after weighing.

[0027] A fixed plate 12 is fixed to the lower side of the mobile frame 11. The weighing assembly includes a weighing sensor 13 installed on the upper side of the fixed plate 12. A weighing plate 14 is installed on the upper side of the weighing sensor 13. The weighing plate 14 is located at the discharge port of the collection box 8 and blocks and seals the discharge port. By blocking and sealing the discharge port of the collection box 8 with the weighing plate 14, the metering is carried out in a sealed environment, reducing the safety hazards caused by gunpowder floating outward, and also reducing gunpowder waste. After the gunpowder falls on the upper side of the weighing plate 14, the weighing sensor 13 weighs the gunpowder to ensure the quality of fireworks production.

[0028] Positioning plates 18 are fixed on both sides of the support frame 2. The positioning plates 18 are located under the moving frame 11. A telescopic cylinder 19 is installed on the side of the collection box 8. The telescopic end of the telescopic cylinder 19 is connected and fixed to the side of the moving frame 11. The telescopic cylinder 19 includes, but is not limited to, a servo electric cylinder or an electric hydraulic cylinder. The positioning plates 18 support and limit the moving frame 11. During the movement of the moving frame 11, the positioning plates 18 play a guiding role to ensure the stability of the moving frame 11 during movement. After the weighing component finishes weighing the gunpowder, it controls the telescopic cylinder 19 to drive the moving frame 11 to move. When the weighing plate 14 moves away from under the collection box 8, the discharge port moves to under the collection box 8 to facilitate the discharge of the weighed gunpowder in the collection box 8 through the discharge port. During the movement of the moving frame 11, the gunpowder on the upper side of the weighing plate 14 at the bottom of the collection box 8 is cleaned to avoid residual gunpowder on the weighing plate 14 from affecting the weighing accuracy.

[0029] A hopper 15 is installed on the lower side of the mobile frame 11 near the discharge port. A baffle 16 is rotatably installed on the side of the mobile frame 11 to cover and seal the hopper 15. When the gunpowder is discharged from the discharge port, it falls into the hopper 15. Personnel can open the hopper 15 by rotating the baffle 16 to take out the weighed gunpowder. The baffle 16 is designed to reduce the floating of gunpowder in the air. Preferably, the baffle 16 is fixed to the hopper 15 by magnetic attraction. A protective plate 17 is installed on the side of the collection box 8 to cover and seal the discharge port. The protective plate 17 is slidably connected to the mobile frame 11. During the sliding of the mobile frame 11, the protective plate 17 covers and seals the discharge port on the side of the mobile frame 11 to reduce the amount of gunpowder floating to the outside through the discharge port.
