Description
Technical Field
[0001] The utility model belongs to the technical field of fireworks production, in particular to a flip filling device for a fireworks inner tube. Background Art
[0002] In the production process of combined fireworks, the combined fireworks need to be filled with the fireworks inner tube into the fireworks outer tube. In this process, either a single fireworks inner tube is manually placed into the fireworks outer tube, or a semi-automatic filling machine is used to directly fill the fireworks inner tube into the fireworks outer tube. However, the fireworks inner tube needs to be manually placed vertically into the semi-automatic filling machine before it can be filled using the semi-automatic filling machine. Since the fireworks inner tube is manually placed, it is easy for the fireworks inner tube to be missed inside the combined fireworks outer tube, requiring additional filling, wasting filling time and reducing the use efficiency. At the same time, since it needs to be manually placed vertically, the horizontal fireworks inner tube cannot be vertically flipped. If the shape of the fireworks inner tube is irregular, it is easy to get stuck, resulting in the need for manual unblocking, which slows down the filling speed, reduces the filling efficiency of the fireworks inner tube, and is inconvenient to use. Therefore, the utility model provides a flipping and filling device for fireworks inner tubes to solve the problems raised in the above background technology. Utility Model Content

[0040] The specific working principle of this utility model:
[0041] During use, when the firework inner tube is on the feed block, the drive motor 10 is manually started to drive the screw rod 19 to rotate.
[0042] To push the push plate 11 on the connecting frame 9 to slide in the direction of the feed block. Then, when the push plate 11 moves on the feed block, the push column 12 welded at the bottom of the push plate 11 will push the firework inner tube on the feed block toward the flip block 201. When the firework inner tube enters the push hole 8 of the flip block 201, the infrared sensor 15 on the side of the support frame 1 detects the firework inner tube in the push hole 8 through the detection probe 14. Then, the detection probe 14 transmits the electrical signal to the infrared sensor through the electrical connection, so that the infrared sensor transmits the electrical signal to the infrared sensor. The signal is transmitted to the electromagnetic valve switches of the first telescopic cylinder 303, the second telescopic cylinder 4 and the third telescopic cylinder 204 respectively, so that the telescopic end of the first telescopic cylinder 303 starts to drive the connecting rod 302 to extend downward, and then the first telescopic cylinder 303 pushes the fixed frame 301 downward through the connecting rod 302, and then the electromagnetic valve switch of the second telescopic cylinder 4 is turned on, so that the telescopic end of the second telescopic cylinder 4 starts to extend downward, so that the second telescopic cylinder 4 starts to drive the moving plate 304 to move downward in the fixed frame 301, and then the moving plate 304 drives the filling column 305 to move downward to the flip plate, and at the same time, the electromagnetic valve switch in the third telescopic cylinder 204 is turned on, so that the third telescopic cylinder 204 extends downward to drive the clamping block 203 to clamp the round protrusion 202 and move downward, so that the flip block 201 rotates 90 degrees on the surface of the fixed rod 13, so that the flip block 201 drives the fireworks inner tube in the pushing hole 8 to align with the filling column 305, and then the filling column 305 moves downward to push the fireworks inner tube in the pushing hole 8 to the docking hole column 306, and the filling column 305 fills the fireworks inner tube into the docking hole column 306. When the firework inner tube is in the hole column 306, if the firework inner tube is of irregular shape, the firework inner tube will drive the docking hole column 306 to squeeze the spring 307 to swing back and forth in the flange hole 18 of the cover plate 16 through its own irregular shape, so that the firework inner tube naturally falls into the firework outer tube through the back and forth swing of the docking hole column 306, and the docking hole column 306 automatically adjusts its position, and the firework inner tube does not get stuck in the docking hole column 306. Subsequently, the firework inner tube begins to fall into the firework outer tube due to the influence of gravity, thereby achieving rapid filling and improving filling efficiency.
