[0002] In the fireworks production process, the quality of the gunpowder filling in the inner tube plays a decisive role in the fireworks' ignition effect and safety. Traditionally, the filling of gunpowder in fireworks inner tubes mostly relies on manual operation, which is not only inefficient but also poses significant safety hazards.

An intermediate plate position adjustment mechanism is installed on the base plate at a position corresponding to the intermediate plate. Filling holes are evenly formed on the base plate, and through holes are evenly formed at the bottom of the gunpowder storage box.

[0006] Furthermore, it also includes a sliding groove, which is formed on the middle plate, and the middle plate is slidably connected to the bottom plate and the gunpowder storage box to the left and right respectively through the sliding groove.

[0007] Furthermore, the intermediate plate position adjustment mechanism includes a cylinder and a push block. There are two sets of cylinders, which are symmetrically installed on the top left and right sides of the base plate. The push block is fixed to the telescopic end of the cylinder and is set to correspond to the position of the intermediate plate.

[0008] Furthermore, the gunpowder storage box is a transparent box.

[0009] Furthermore, it also includes a photoelectric sensor, which is installed on the top of the base plate and is positioned corresponding to the location of the gunpowder storage box.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This fireworks outer tube propellant filling device has the following advantages:

[0011] 1. By cooperating with the quantitative groove on the intermediate plate, the through hole of the gunpowder storage box, and the filling hole of the bottom plate, it is possible to achieve precise control of the filling amount per batch, avoid human operation error, and ensure the consistency of the gunpowder filling amount in the inner tube of the fireworks.

[0012] 2. The intermediate plate position adjustment mechanism drives the intermediate plate to slide through a cylinder and a pusher block, which can automate the filling process and thus improve production efficiency. Attached Figure Description

[0018] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0019] Please see Figure 1-4 This embodiment provides a technical solution: a fireworks outer tube propellant filling device, including a base plate 1, a gunpowder storage box 2 fixed on the top of the base plate 1, an intermediate plate 3 movably connected between the gunpowder storage box 2 and the base plate 1, and a metering groove 9 evenly opened on the intermediate plate 3, an intermediate plate position adjustment mechanism 4 installed on the base plate 1 corresponding to the position of the intermediate plate 3, filling holes 8 evenly opened on the base plate 1, and through holes 7 evenly opened at the bottom of the gunpowder storage box 2.

[0020] It also includes a chute 6, which is formed on the intermediate plate 3. The intermediate plate 3 is slidably connected to the base plate 1 and the gunpowder storage box 2 via the chute 6. The intermediate plate position adjustment mechanism 4 includes a cylinder 41 and a pusher block 42. There are two sets of cylinders 41, which are symmetrically installed on the top left and right sides of the base plate 1. The pusher block 42 is fixed to the telescopic end of the cylinder 41 and is set to correspond to the position of the intermediate plate 3. In the initial state, the metering groove 9 of the intermediate plate 3 is aligned with the through hole 7 of the gunpowder storage box 2. The gunpowder falls into the metering groove 9 by gravity, completing the metered dispensing. When cylinder 41 is activated, pusher block 42 pushes intermediate plate 3 to slide to the right along slide groove 6, aligning metering groove 9 with filling hole 8 of bottom plate 1. Gunpowder falls from metering groove 9 through filling hole 8 into the inner tube of fireworks below, completing the filling process. After filling, right cylinder 41 is activated, pushing intermediate plate 3 to slide to the left to reset, aligning metering groove 9 with through hole 7 again, and proceeding to the next material feeding. This allows for precise control of the filling amount per cycle, avoiding human error and ensuring the consistency of gunpowder filling in the inner tube of fireworks. It also automates the filling process, thereby improving production efficiency.

[0021] The gunpowder storage box 2 is a transparent box and also includes a photoelectric sensor 5. The photoelectric sensor 5 is installed on the top of the base plate 1 and is set to correspond to the position of the gunpowder storage box 2. The device is placed on a stable working site to ensure that the base plate 1 is level. Gunpowder is filled into the gunpowder storage box 2. The amount of gunpowder stored can be directly observed through the transparent box. At the same time, the photoelectric sensor 5 monitors the gunpowder height in real time. When it is lower than the set value, an alarm is issued to prompt the addition of material. It can monitor the amount of gunpowder stored in real time to prevent abnormal filling due to lack of material, while reducing the risk of manual contact with gunpowder and enhancing the safety of production.

[0022] The working principle of the firework outer tube propellant filling device provided by this utility model is as follows: The device is placed on a stable working site to ensure that the base plate 1 is level. Gunpowder is filled into the gunpowder storage box 2. The amount of gunpowder stored can be directly observed through the transparent box. At the same time, the photoelectric sensor 5 monitors the gunpowder height in real time. When it is lower than the set value, an alarm is issued to prompt the addition of material. In the initial state, the metering groove 9 of the middle plate 3 is aligned with the through hole 7 of the gunpowder storage box 2. The gunpowder falls into the metering groove 9 by gravity, completing the metering. The left cylinder 41 is activated, and the pusher 42 pushes the middle plate 3 to slide to the right along the slide 6, so that the metering groove 9 is aligned with the filling hole 8 of the base plate 1. The gunpowder falls from the metering groove 9 through the filling hole 8 into the inner tube of the firework below, completing the filling process. After filling is completed, the right cylinder 41 is activated, and the middle plate 3 is pushed to slide to the left to reset, so that the metering groove 9 is aligned with the through hole 7 again, and the next material removal begins.
