[0021] In order to make those skilled in the art better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the drawings.

[0022] like Figures 1-4 As shown, a high-efficiency filling device for fireworks production includes a lower mold 1 and an upper mold 11 on top of it, which is equipped with a discharge port 12 and a material pipe 13. It also includes a vertical bar 4 fixedly installed in the material pipe 13, and a vertical rod 41 fixedly installed on the vertical bar 4 in the discharge port 12.

[0023] A rotating block 32 is movably installed on the upper end of the discharge port 12. A swing rod 33 arranged in a circle and rotating downward is installed on the rotating block 32. The swing rod 33 abuts against the upright rod 41.

[0024] Specifically, the opening and closing between the lower mold 1 and the upper mold 11 is existing technology and will not be described in detail here. The upper mold 11 has a chamber for containing gunpowder. The cover on the upper mold 11 has a gunpowder inlet, and the discharge port 12 is a recess that connects to the material pipe 13 so that the gunpowder can be collected through the discharge port 12 and sent into the material pipe 13 for discharge.

[0025] Furthermore, the length and width of the strip-shaped vertical bar 4 are both smaller than the diameter of the material tube 13, so as not to interfere with the normal material feeding of the material tube 13. The vertical rod 41 is installed upward in the middle of the vertical bar 4, and the vertical rod 41 extends out of the discharge port 12 and is located in the upper mold 11 cavity.

[0026] Furthermore, the rotating block 32 moves downward in a spiral, meaning that the swing arm 33 rotates as it moves downward. The number of swing arms 33 is less than the number of uprights 41. The uprights 41 are specifically elastic metal rods made of existing technology, which will not be described in detail here.

[0027] The rotating block 32 drives multiple swing rods 33 to stir the gunpowder in the chamber at the upper end of the discharge port 12, reducing gunpowder agglomeration and affecting the discharge of the material pipe 13, ensuring the particle size of the gunpowder before entering the material pipe 13. The downward moving swing rods 33 also gradually increase the stirring area, improving the smoothness of gunpowder discharge. The swing rods 33 eventually impact and push multiple upright rods 41, causing the bent upright rods 41 to turn over the gunpowder inside the discharge port 12. At the same time, the upright rods 41 that are detached from the swing rods 33 continuously shake, which also enhances the turning effect of the gunpowder, making the gunpowder discharge efficiency higher. The swinging upright rods 41 also stir and turn over the inside of the material pipe 13, achieving the purpose of efficient conveying and discharging of gunpowder, further reducing problems such as gunpowder blockage in the material pipe 13.

[0028] As a further embodiment of this utility model, a swing ring 34 is fixedly installed on the swing rod 33, and the swing ring 34 pushes against the end of the upright rod 41 to bend the upright rod 41.

[0029] Specifically, the multi-ringed pendulum 34 contacts the upper ends of multiple uprights 41 so that the downward-moving pendulum 34 provides downward pressure on the uprights 41.

[0030] The downward-moving swing ring 34 pushes the upright rod 41 downward, causing the upright rod 41 to bend vertically into an arc shape, increasing the area for stirring the gunpowder. At the same time, the end of the upright rod 41, after being bent by force, will actively detach from the swing ring 34, increasing the shaking range of the end of the upright rod 41, making the stirring effect more random and efficient.

[0031] As another embodiment further provided by this utility model, a screw 3 for the rotating block 32 to move is fixedly installed in the upper mold 11, and a pressure ring 23 for pushing the rotating block 32 is vertically movable on the screw 3.

[0032] Specifically, the screw 3 is fixedly installed on the inner wall of the upper mold 11 cover, and the lower end of the screw 3 is rotatably provided with an end block 31 for limiting the rotating block 32. A spring is fixedly installed between the end block 31 and the rotating block 32, and the rotating block 32 is threadedly connected to the screw 3.

[0033] Furthermore, the pressure ring 23 is sleeved on the outside of the screw 3, and the pressure ring 23 only maintains sliding contact with the upper end face of the rotating block 32, so as to facilitate the pressure ring 23 pressing down on the rotating block 32 to move.

[0034] The pressure ring 23 provides downward force to the rotating block 32, causing the rotating block 32 to rotate on the screw 3, which facilitates the rotation and downward movement of the swing rod 33 and the swing ring 34.

[0035] As another embodiment further provided by this utility model, a main frame 21 is movably arranged in the upper mold 11, and a plurality of pressure rods 22 are fixedly installed on the main frame 21, with a pressure ring 23 fixedly installed at the end of the pressure rod 22.

[0036] Specifically, the number of pressure rods 22 corresponds to the number of discharge ports 12.

[0037] The main frame 21 provides an active driving force, which makes the force on the multiple pressure rods 22 more uniform, so that the multiple rotating blocks 32 can move down the thread synchronously. At the same time, the multiple pressure rods 22 can also move stably in the upper mold 11, and can also play a certain role in propelling the gunpowder.

[0038] As another embodiment of this utility model, an electric push rod 2 is fixedly installed on the upper mold 11, and the main frame 21 is fixedly installed on the output end of the electric push rod 2.

[0039] Specifically, the electric push rod 2 is fixedly installed on the cover of the upper mold 11, and the electric push rod 2 is powered by 220V voltage, which is existing technology and will not be described in detail here.

[0040] The electric push rod 2 provides an active thrust, reducing power consumption. At the same time, it can make multiple rotating blocks 32 move synchronously, so that the gunpowder stirring in the upper mold 11 chamber is in a synchronous state, improving the efficiency of gunpowder stirring and turning.

[0041] Working principle: The rotating block 32 drives multiple swing rods 33 to stir the gunpowder in the chamber at the upper end of the discharge port 12, reducing the accumulation of gunpowder agglomerates that would affect the discharge of the material pipe 13. The downward-moving swing rods 33 also gradually increase the stirring area. The swing rods 33 eventually impact and push multiple upright rods 41, causing the bent upright rods 41 to tumble the gunpowder inside the discharge port 12. At the same time, the upright rods 41, which are detached from the swing rods 33, continuously shake, which also enhances the tumbling effect of the gunpowder. The swinging upright rods 41 also stir and tumble the inside of the material pipe 13, achieving the purpose of efficiently conveying and discharging the gunpowder, further reducing the problem of gunpowder blockage in the material pipe 13. The downward-moving swing ring 34 pushes the upright rods 41 downward, bending them vertically into an arc shape and increasing the area for tumbling the gunpowder. At the same time, the end of the upright rod 41, after being bent by force, will actively detach from the swing ring 34, increasing the shaking range of the end of the upright rod 41, making the stirring effect more random and efficient.

[0042] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
