Description

Technical Field

[0001] This utility model relates to the field of combined fireworks production technology, and in particular to an automatic loading machine for combined fireworks production. Background Technology

[0002] The continuous firing of combination fireworks showcases their unique beauty and charm. When producing combination fireworks, gunpowder powder needs to be loaded into the fireworks container to generate a reverse thrust, which pushes the ignited fireworks ball into the air and causes an explosion after firing.

[0003] In the prior art, patent CN 222926085 U discloses a charging device for the production of combination fireworks. It uses a first motor and a second motor to drive a first screw and a second screw to rotate, causing a first threaded block and a second threaded block to move laterally and longitudinally, respectively. This, in turn, drives a first moving rod and a second moving rod to move laterally and longitudinally within a rectangular frame. This facilitates the movement of the moving block through the first and second through holes within the rectangular frame, and further facilitates the movement of the filling funnel on the combination fireworks body through the cross-shaped mechanism. This allows for the convenient charging of several individual cylinders within the combination fireworks. However, it cannot quantitatively charge the gunpowder, resulting in inconsistent production quality of the combination fireworks and failing to meet usage requirements. Utility Model Content

The machine keeps the amount of propellant loaded in each operation consistent, which improves the quantitative accuracy of propellant loading for combination fireworks and ensures the stability of product quality. At the same time, it can load multiple fireworks tubes at once, thereby improving production efficiency and effectively solving the problems in the background art.

[0005] To achieve the aforementioned objective, this utility model adopts the following technical solution:

[0006] An automatic propellant loading machine for the production of combination fireworks includes a propellant loading box, a support frame fixed to the side of the propellant loading box, a PLC controller mounted on the side of the support frame, a rotating roller rotatably connected to the inside of the propellant loading box via bearings, a metering groove evenly distributed on the rotating roller, and a discharge auxiliary unit mounted inside the metering groove, a feeding hopper communicating with the inside of the metering groove fixed to the top of the propellant loading box, and several propellant loading tubes communicating with the inside of the metering groove fixed to the bottom of the propellant loading box, a drive mechanism for driving the rotating roller to rotate mounted on the side of the feeding hopper, and the PLC controller electrically connected to an external power supply.

[0007] Furthermore, the bottom of the metering groove has a conical structure.

[0008] Furthermore, the discharge auxiliary unit includes a vibrating rod, which is movably connected to the metering trough, with the vibrating rod extending into the inner side of the metering trough.

[0009] Furthermore, the discharge auxiliary unit also includes a piston and a piston chamber. The piston chamber is evenly distributed on the rotating roller, and the piston is movably disposed inside the piston chamber. One end of the vibrating rod is fixedly connected to the piston.

[0010] Furthermore, the discharge auxiliary unit also includes an air pump, a rotary joint, and a connecting pipe. The connecting pipe is fixed in the middle of the rotating roller and communicates with the inside of the piston chamber. The air pump is installed on the side of the support frame. The pump port of the air pump is connected to the connecting pipe, and the end of the connecting pipe is rotatably connected to the pump port of the air pump through the rotary joint. The air pump is electrically connected to the PLC controller.

[0011] Furthermore, the drive mechanism includes a servo motor, a worm gear, a worm wheel, and a mounting base. The mounting base is fixed to the side of the feed hopper. The worm gear is rotatably mounted inside the mounting base.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This automatic loading machine for combined fireworks production has the following advantages:

[0013] 1. The agent enters the metering tank through the feed hopper. When the metering tank is full of agent, the drive mechanism drives the rotating roller to rotate, so that the metering tank containing the agent rotates to the top of the charging tube.

[0021] Please see Figure 1-4 This embodiment provides a technical solution: an automatic loading machine for combined fireworks production, including a loading box 1, a support frame 2 fixed to the side of the loading box 1, a PLC controller 6 installed on the side of the support frame 2, a rotating roller 7 rotatably connected to the inside of the loading box 1 via a bearing 8, a metering groove 10 evenly opened on the rotating roller 7, and a discharge auxiliary unit 4 installed on the inside of the metering groove 10, a feeding hopper 5 connected to the inside of the metering groove 10 fixed to the top of the loading box 1, and several loading tubes 9 connected to the inside of the metering groove 10 fixed to the bottom of the loading box 1, a drive mechanism 3 for driving the rotating roller 7 to rotate installed on the side of the feeding hopper 5, the PLC controller 6 electrically connected to an external power supply, the metering groove 10 for holding a metered amount of agent, which is evenly distributed on the rotating roller 7, and by controlling the rotation of the rotating roller 7, the agent can be continuously and quantitatively transferred.

[0022] The bottom of the metering tank 10 has a conical structure, which helps the reagent to slide smoothly under the action of gravity and reduce residue.

[0023] The discharge auxiliary unit 4 includes a vibrating rod 44, which is movably connected to the metering trough 10. The vibrating rod 44 extends into the inner side of the metering trough 10. The discharge auxiliary unit 4 also includes a piston 45 and a piston chamber 46. The piston chamber 46 is evenly distributed on the rotating roller 7, and the piston 45 is movably disposed inside the piston chamber 46. One end of the vibrating rod 44 is fixedly connected to the piston 45. The discharge auxiliary unit 4 also includes an air pump 41, a rotary joint 42, and a connecting pipe 43. The connecting pipe 43 is fixed in the middle of the rotating roller 7 and communicates with the inside of the piston chamber 46. The air pump 41 is mounted on the side of the support frame 2. The pump port of the air pump 41 is connected to the connecting pipe 43, and the end of the connecting pipe 43 is rotatably connected to the pump port of the air pump 41 via the rotary joint 42. The air pump 41 is electrically connected to a PLC controller 6. The controller 6 controls the air pump 41 to start. The air pump 41 delivers gas to the piston chamber 46 through the connecting pipe 43, which pushes the piston 45 to move. The piston 45 drives the vibrating rod 44 to vibrate, thereby assisting the agent to fall smoothly from the metering tank 10 into the loading tube 9 to complete one loading process. This can effectively reduce the agent residue, improve the unloading efficiency, and avoid subsequent production problems caused by the agent residue.

[0024] The drive mechanism 3 includes a servo motor 31, a worm gear 32, a worm wheel 33, and a mounting base 34. The mounting base 34 is fixed to the side of the feed hopper 5. The worm gear 32 is rotatably mounted inside the mounting base 34.

The medicine enters the metering tank 10 through the feed hopper 5. When the metering tank 10 is full of medicine, the PLC... The controller 6 controls the operation of the servo motor 31. The output shaft of the servo motor 31 drives the worm gear 32 to rotate. The worm gear 32 meshes with the worm wheel 33, which drives the rotating roller 7 to rotate. This causes the metering tank 10 containing the agent to rotate above the charging tube 9. The firework tubes of the combined fireworks are placed below the charging tube 9 and aligned with it. The amount of agent added each time is consistent, which improves the metering accuracy of the combined fireworks and ensures the stability of product quality. At the same time, it can perform charging operations on multiple firework tubes at one time, thereby improving production efficiency.

The worm gear 32 meshes with the worm wheel 33. The worm wheel 33 drives the rotating roller 7 to rotate, thereby rotating the metering tank 10 containing the agent to the top of the loading tube 9. At this time, the PLC controller 6 controls the air pump 41 to start. The air pump 41 delivers gas to the piston chamber 46 through the connecting pipe 43, pushing the piston 45 to move. The piston 45 drives the vibrating rod 44 to vibrate, thereby assisting the agent to fall smoothly from the metering tank 10 into the loading tube 9, completing one loading process.
