[0002] Combination fireworks consist of multiple single tubes arranged together, producing sound, light, color, and floating effects when set off. The materials in each single tube of combination fireworks are usually filled automatically by automated equipment, including the filling of gunpowder, confetti, and effect inner tubes. In order to ensure that the fillings in each single tube meet the qualification standards, they need to be tested one by one after the filling process.

[0003] Chinese patent document CN222318806U discloses a fireworks visual inspection device and a fireworks production line, relating to the field of fireworks production equipment technology.

Detailed Implementation

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figure 1As shown, a device for testing finished fireworks products includes a base 1, a conveyor belt 2 rotatably connected to the inner wall of the middle part of the base 1, a U-shaped frame 3 fixedly connected to the upper surface of the front and rear parts of the base 1, a cargo adjustment component 4 fixedly connected to the inner wall of the U-shaped frame 3 and located on the upper surface of the conveyor belt 2, a second U-shaped frame 5 fixedly connected to the upper surface of the front and rear parts of the base 1 and located on the right side of the first U-shaped frame 3, lifting components 6 fixedly connected to the inner walls of the front and rear parts of the second U-shaped frame 5, a camera detection component 7 fixedly connected to the opposite surfaces of the upper parts of the two lifting components 6 and located above the conveyor belt 2, and the outer wall of the camera detection component 7 movably sleeved with the inner wall of the middle part of the second U-shaped frame 5.

[0027] First, the two lifting components 6 enable the camera detection component 7 to adjust its height as needed. Then, the finished fireworks are placed on the upper surface of the conveyor belt 2. Under the action of the conveyor belt 2, the finished fireworks can move into the interior of the U-shaped frame 3. At this time, under the action of the cargo adjustment component 4, the position of the finished fireworks can be adjusted. Then, the adjusted finished fireworks continue to move into the interior of the U-shaped frame 5 under the action of the conveyor belt 2, and then are detected by the camera detection component 7.

[0028] like Figure 2 As shown, the two lifting components 6 include two electric push rods 61. The outer walls of the lower part of the two electric push rods 61 are fixedly connected to the inner cavities of the front and rear parts of the U-shaped frame 5, respectively. The output ends of the two electric push rods 61 are fixedly connected to connecting blocks 62. The outer walls of the two connecting blocks 62 are movably sleeved with the inner walls of the front and rear parts of the U-shaped frame 5, respectively. The opposite surfaces of the two connecting blocks 62 are fixedly connected to the front and rear sides of the camera detection component 7, respectively.

[0029] The electric push rod 61 enables the connecting block 62 to move the camera detection component 7 up and down, thereby adjusting the height of the camera detection component 7 according to the height of the finished fireworks, thus improving the accuracy of the detection.

[0030] The inner cavities of the left and right parts of the connecting block 62 are slidably connected with guide rods 63, and the two guide rods 63 are located on the left and right sides of the electric push rod 61 respectively. The upper and lower sides of the two guide rods 63 are fixedly connected to the inner wall of the U-shaped frame 5 respectively.

[0031] The guide rod 63 enables the connecting block 62 to move stably up and down, thereby enabling the camera detection component 7 to move stably up and down, thus playing a guiding role.

[0032] like Figure 3As shown, the cargo adjustment assembly 4 includes two adjusting horizontal plates 43. The outer walls of the two adjusting horizontal plates 43 are movably sleeved with the inner walls of the front and rear parts of the U-shaped frame 3, respectively. A connecting frame 44 is fixedly connected to the lower surface of each of the two adjusting horizontal plates 43, and a support shell 45 is fixedly connected to the lower surface of each of the two connecting frames 44. Several limiting rods 46 are rotatably connected to the inner walls of each of the two support shells 45. The outer walls of the connecting frame 44 and the support shell 45 are movably sleeved with the inner walls of the U-shaped frame 3, respectively.

[0033] By using several limiting rods 46, the finished fireworks can be guided to the middle of the upper surface of the conveyor belt 2, which facilitates the camera detection component 7 to detect the finished fireworks and improves the accuracy of the detection.

[0034] like Figure 4 As shown, a motor 41 is fixedly connected to the inner cavity of the front part of the U-shaped frame 3, and a threaded rod 42 is fixedly connected to the output end of the motor 41. The outer walls of the front and rear parts of the threaded rod 42 are rotatably connected to the inner cavities of the front and rear parts of the U-shaped frame 3, respectively. The outer walls of the front and rear parts of the threaded rod 42 are threadedly connected to the inner cavities of the middle parts of the two adjusting horizontal plates 43, respectively.

[0035] The motor 41 rotates the threaded rod 42, which causes the two adjusting plates 43 to move toward each other. This allows the two support shells 45 to be positioned according to the size of the finished fireworks, making it easier to promote and use.

[0036] like Figure 5 As shown, the inner cavities of the left and right parts of the two adjusting horizontal plates 43 are slidably connected to two guide rails 47, and the two guide rails 47 are located on the left and right sides of the motor 41 respectively. The front and rear sides of the two guide rails 47 are fixedly connected to the inner wall of the U-shaped frame 3 respectively.

[0037] The guide rail 47 enables the adjusting plate 43 to stably drive the support shell 45 to move horizontally, thereby playing a guiding role.

[0038] The working principle of this utility model is as follows: First, the electric push rod 61 causes the connecting block 62 to move the camera detection component 7 up and down, thereby adjusting the height of the camera detection component 7 according to the height of the finished fireworks. Then, the motor 41 causes the threaded rod 42 to rotate, thereby causing the two adjusting horizontal plates 43 to move towards each other, allowing the two supporting shells 45 to be positioned according to the size of the finished fireworks. Next, the finished fireworks are placed on the upper surface of the conveyor belt 2. Under the action of the conveyor belt 2, the finished fireworks can move into the interior of the U-shaped frame 3. At this time, the firework is restricted and guided to the middle of the upper surface of the conveyor belt 2 by several limiting rods 46. After adjustment, the finished fireworks continue to move into the interior of the U-shaped frame 5 under the action of the conveyor belt 2, and then are detected by the camera detection component 7.
