Description

Technical Field

[0001] This utility model belongs to the field of fireworks production technology, and in particular relates to an inner tube gunpowder filling device for fireworks production. Background Technology

[0002] Fireworks are actually similar in structure to firecrackers, both containing gunpowder and a fuse. To achieve good performance effects, fireworks and firework shells need to be filled with a large amount of gunpowder for launching and exploding. Therefore, filling equipment is needed in the production process of fireworks.

[0003] Utility model patent CN221685326U discloses a gunpowder filling device for fireworks production, including a filling machine, a fireworks inner cylinder, and a discharge head. The left side of the inner side of the filling machine is connected to the top of the discharge head. A placement seat is fixedly connected to the left side of the bottom of the inner side of the filling machine. The bottom of the fireworks inner cylinder is movably connected to the top of the placement seat. A baffle is provided on the top of both sides of the fireworks inner cylinder. A connecting rod is fixedly connected to the outer side of the baffle. Electromagnets are fixedly connected to both sides of the placement seat. An iron plate is magnetically attracted to the outer side of the electromagnet. The device is fixedly connected to the end of the connecting rod away from the blocking cover. Limiting components are fixedly connected to the front and rear sides of both sides of the placement seat. A reinforcing mechanism is fixedly sleeved on the surface of the connecting rod. Before filling the inner cylinder with gunpowder, the filling of the inner cylinder needs to be manually corrected to ensure that the gunpowder can be smoothly filled into the inner cylinder. This step can only be performed once each time, which reduces the efficiency of filling the inner cylinder with gunpowder. Furthermore, there is no timely monitoring of the consumption of gunpowder filling, so it is impossible to effectively replenish the gunpowder. Therefore, an inner cylinder gunpowder filling device for fireworks production is proposed. Utility Model Content

Multiple inner cylinder support frames 14 are fixedly connected to the rotating disk 13. A third reinforcing frame 15 is fixedly connected to the inner cylinder support frame 14. An electric push rod 16 is fixedly installed on the third reinforcing frame 15. A connecting rod 17 is connected to the top end of the telescopic rod of the electric push rod 16. The connecting rod 17 is slidably connected to the inner cylinder support frame 14. A top plate 18 is connected to the top end of the connecting rod 17. A groove is formed on the top plate 18. A first weight sensor 19 is installed at the bottom to detect the weight of the gunpowder in the inner cylinder. A signal transmitter 20 is installed on the inner cylinder support frame 14, and a second signal receiver 21 is installed on the fixed base plate 1. A support frame 22 is fixedly connected to the fixed base plate 1, and a filling box 23 is fixedly connected to the support frame 22. A discharge pipe 24 is fixedly connected to the filling box 23, and an electric valve 25 is installed on the discharge pipe 24. A second weight sensor 26 is installed on the filling box 23 to detect the amount of gunpowder stored in the filling box 23. A conveying connection frame 28 connects the fixed base plate 1 and the support frame 22. A conveyor frame 29 is fixedly connected to the conveyor connecting frame 28. A fourth reinforcing frame 30 is fixedly connected to the conveyor frame 29. A third drive motor 31 is fixedly installed on the fourth reinforcing frame 30. A third rotating shaft 32 is connected to the output shaft of the third drive motor 31. The third rotating shaft 32 is rotatably connected to the conveyor frame 29. A first conveyor wheel 33 is rotatably connected to the conveyor frame 29. The first conveyor wheel 33 is connected to the third rotating shaft 32.

[0021] A buzzer is installed on controller 2.

[0022] An indicator light 27 is installed on the support bracket 22.

[0023] The working principle of this utility model is as follows: the second weight sensor is provided with a first threshold and a second threshold, and the value of the first threshold is greater than the value of the second threshold.

[0024] The third drive motor drives the third shaft, the first conveyor wheel, the second conveyor wheel, and the conveyor belt to rotate. Then, the gunpowder to be filled is placed on the conveyor belt, which transports the gunpowder into the filling box, thus completing the gunpowder transportation. When the weight of the gunpowder in the filling box reaches the first threshold preset by the second weight sensor, the buzzer is controlled to sound for a period of time, and the third drive motor is controlled to stop working. At this time, the filling box has been loaded with the predetermined weight of gunpowder.

[0025] Multiple inner cylinders are placed sequentially into the feeding tray carrier trough. When the inner cylinder needs to be filled with gunpowder, the first drive motor is controlled to drive the first rotating shaft and the feeding tray to rotate. When the feeding tray carrier trough is aligned with the feeding pipe channel, the inner cylinder will slide down into the inner cylinder support frame through the feeding pipe, thereby realizing the automatic delivery of the inner cylinder.

[0026] The second drive motor drives the second rotating shaft, rotating disk, inner cylinder support frame, and signal transmitter to rotate. When the signal transmitter rotates to align with the third signal receiver, the third signal receiver receives the signal emitted by the signal transmitter, thereby controlling the second drive motor to stop working. At the same time, the electric valve is controlled to open the discharge pipe channel, and the gunpowder falls into the inner cylinder through the discharge pipe channel, thus completing the gunpowder filling process. When the weight of the gunpowder in the inner cylinder reaches the preset threshold of the first weight sensor, the electric valve is controlled to close the discharge pipe channel. At the same time, the second drive motor is controlled to continue driving the second rotating shaft, rotating disk, inner cylinder support frame, and signal transmitter to rotate. When the signal transmitter rotates to align with the second signal receiver, the second signal receiver receives the signal emitted by the signal transmitter, thereby controlling the second drive motor to stop working. At the same time, the electric push rod is controlled to drive the connecting rod and the top plate to rise, so that the top plate lifts the inner cylinder. Then, the inner cylinder can be removed from the top plate.

[0027] After the inner cylinder is removed, when the second drive motor drives the second rotating shaft, the rotating disk, the inner cylinder support frame and the signal transmitter to rotate, when the signal transmitter rotates to align with the first signal receiver, the first signal receiver receives the signal emitted by the signal transmitter, thereby controlling the second drive motor to stop working, and at the same time controlling the electric push rod to drive the connecting rod and the top plate to descend to the reset position, so that the next inner cylinder can be put in.

[0028] When the weight of the gunpowder in the filling box is lower than the second threshold preset by the second weight sensor, the indicator light will illuminate to remind the staff to replenish the gunpowder in the filling box. At this time, the steps of transporting gunpowder by the conveyor belt can be repeated. When the weight of the gunpowder in the filling box reaches the first threshold preset by the second weight sensor, the buzzer will sound for a period of time, and the indicator light will turn off.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
