Abstract
Description
Technical Field
[0001] This utility model relates to the field of fireworks production, and in particular to an automatic loading device for fireworks and firecrackers production. Background Technology
[0002] Fireworks, also known as sparklers, fireworks, or firecrackers, are entertainment items made from gunpowder and used to produce sound, light, and color. They were invented relatively early by the Chinese working people and are often used in grand ceremonies or performances. The colors of fireworks are caused by the different flame colors resulting from the burning of different metals. Fireworks utilize the combustion of various metal powders at high temperatures to create a variety of dazzling colors; different metals produce different effects and emit different colors of light. During the production process, gunpowder needs to be loaded into the fireworks tubes. However, existing gunpowder loading devices are difficult to use effectively to hold fireworks tubes of different diameters, and the gunpowder is prone to clogging during loading, affecting the efficiency of the loading process. Utility Model Content
[0003] The present invention aims to address the above-mentioned deficiencies by providing an automatic loading device for fireworks and firecrackers production that can fix fireworks tubes of different diameters, prevent gunpowder blockage, and improve loading efficiency.
[0004] The technical solution is: an automatic charging device for fireworks and firecrackers production, comprising a base, an electric slide rail fixedly connected to the base, two sliders slidably connected to the electric slide rail, a placement tray connected between the two sliders, a plurality of fireworks tube placement slots on the placement tray, a clamping component on the placement tray for fixing the fireworks tubes, and a gunpowder adding component and a gunpowder adding auxiliary component on the base. The gunpowder adding component is used to inject gunpowder into the fireworks tubes, and the gunpowder adding auxiliary component is used to prevent gunpowder blockage.
[0005] To further explain, the clamping component includes clamping rods, and several clamping rods are slidably connected to the placement plate. Sleeve rods are slidably connected to the clamping rods. A pressure spring is connected between the clamping rods and the sleeve rods. Two limit rods are fixedly connected to the electric slide rail.
[0006] To further explain, the gunpowder adding component includes a mounting bracket, the mounting bracket is fixedly connected to the base, an electric hydraulic cylinder is fixedly connected to the mounting bracket, a hopper is fixedly connected to the mounting bracket, a feeding pipe is fixed to the telescopic rod of the electric hydraulic cylinder, and the feeding pipe and the hopper are slidably connected.
[0007] To further explain, the gunpowder adding auxiliary component includes a push rod, two of which are fixedly connected to the hopper, and two mounting plates are fixedly connected to the telescopic rod of the electric hydraulic cylinder. A top plate is slidably connected to the mounting plate, and a return spring is connected between the top plate and the mounting plate.
[0008] To further explain, the top plate is provided with several convex spheres.
[0009] Beneficial effects: 1. Two of the sleeve rods will be squeezed by the limiting rod, causing the two clamping rods to move closer to each other, so that the firework tube is clamped and fixed by the two clamping rods. If the diameter of the firework tube is large, the firework tube will squeeze the clamping rod, causing the clamping rod to extend into the sleeve rod, and the pressure spring will be compressed. In this way, firework tubes of different diameters can be fixed during filling, improving the applicability of the device.
[0010] 2. The movement of the telescopic rod of the electric hydraulic cylinder will drive the mounting plate and the top plate to move. The top plate will contact the push rod, which will squeeze the convex ball on the top plate, causing the top plate to extend into the mounting plate. The return spring is compressed. After the push rod and the convex ball on the top plate separate, the return spring returns to its original position, driving the top plate to return to its original position. In this way, the contact between the push rod and the convex ball on the top plate will cause the hopper to vibrate, thereby preventing gunpowder blockage and improving filling efficiency.

Detailed Implementation
[0017] The present invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.
[0018] Example 1: An automatic loading device for fireworks and firecrackers production, such as... Figure 1-Figure 5 As shown, the device includes a base 1, on which an electric slide rail 2 is fixedly connected. Two sliders 3 are slidably connected to the electric slide rail 2, and a placement tray 4 is connected between the two sliders 3. The placement tray 4 has several slots for placing firework tubes and a clamping component for fixing the firework tubes. The base 1 is equipped with a gunpowder adding component and a gunpowder adding auxiliary component. The gunpowder adding component is used to inject gunpowder into the firework tubes, and the gunpowder adding auxiliary component is used to prevent gunpowder blockage.
[0019] The clamping component includes clamping rods 5, which are slidably connected to a placement plate 4. Sleeve rods 6 are slidably connected to the clamping rods 5. A pressure spring 7 is connected between the clamping rods 5 and the sleeve rods 6. Two limiting rods 71 are fixedly connected to the electric slide rail 2. The two sleeve rods 6 are squeezed by the limiting rods 71, causing the two clamping rods 5 to move towards each other, so that the firework tube is clamped and fixed by the two clamping rods 5.
[0020] The gunpowder adding component includes a mounting frame 8, which is fixedly connected to the base 1. An electric hydraulic cylinder 9 is fixedly connected to the mounting frame 8, and a hopper 10 is fixedly connected to the mounting frame 8. A feeding pipe 11 is fixedly fixed to the telescopic rod of the electric hydraulic cylinder 9, and the feeding pipe 11 and the hopper 10 are slidably connected.
[0021] Initially, the feed pipe 11 blocks the outlet of the hopper 10. The user first places the firework tube in the placement slot of the placement tray 4. Then, the user activates the electric slide rail 2, causing the slider 3 to rotate along the electric slide rail 2. The rotation of the slide rail drives the placement tray 4 to rotate. When the placement tray 4 moves the firework tube directly below the hopper 10, the slider 3 stops moving. Two of the sleeve rods 6 are squeezed by the limiting rod 71, causing two of the clamping rods 5 to move towards each other, thus clamping and fixing the firework tube. If the diameter of the firework tube is large, the firework tube will squeeze the clamping rod 5, causing the clamping rod 5 to extend into the sleeve rod 6, compressing the pressure spring 7. Then, the user activates the electric hydraulic cylinder 9. When the telescopic rod extends, the extension of the electric hydraulic cylinder 9 will cause the feed pipe 11 to extend into the fireworks tube. The outlet of the hopper 10 will no longer be blocked by the feed pipe 11, and the gunpowder in the hopper 10 will be injected into the fireworks tube through the feed pipe 11. After the gunpowder is injected for a certain period of time, the telescopic rod of the electric hydraulic cylinder 9 will retract, and the retraction of the telescopic rod of the electric hydraulic cylinder 9 will cause the feed pipe 11 to reset. The reset feed pipe 11 will block the outlet of the hopper 10 again. Subsequently, the slider 3 continues to move, the sleeve rod 6 and the limit rod 71 will disengage, and the reset spring 15 will reset, causing the clamping rod 5 to extend out of the sleeve rod 6. Then the user can remove the fireworks tube filled with gunpowder. In this way, fireworks tubes of different diameters can be fixed during filling, improving the applicability of the device.
[0022] Example 2: Based on Example 1, such as Figures 4-5 As shown, the gunpowder adding auxiliary component includes a top rod 12, two top rods 12 are fixedly connected to the hopper 10, two mounting plates 13 are fixedly connected to the telescopic rod of the electric hydraulic cylinder 9, a top plate 14 is slidably connected to the mounting plate 13, and a return spring 15 is connected between the top plate 14 and the mounting plate 13.
[0023] The top plate 14 is provided with a number of convex balls.
[0024] The movement of the telescopic rod of the electric hydraulic cylinder 9 will cause the mounting plate 13 and the top plate 14 to move. The top plate 14 will contact the push rod 12, and the push rod 12 will squeeze the convex ball on the top plate 14, causing the top plate 14 to extend into the mounting plate 13. The return spring 15 will be compressed. After the push rod 12 and the convex ball on the top plate 14 are separated, the return spring 15 will return and drive the top plate 14 to return. In this way, the contact between the push rod 12 and the convex ball on the top plate 14 will cause the hopper 10 to vibrate, thereby preventing gunpowder blockage and improving filling efficiency.

All equivalent substitutions made within the principles of this utility model should be included within the protection scope of this utility model.
