Description

Technical Field

[0001] This utility model relates to a testing device, and more particularly to a fireworks quality testing and classification device. Background Technology

[0002] Fireworks are pyrotechnic products that utilize the light, heat, sound, and color effects produced by the combustion or explosion of pyrotechnics for viewing and celebration. They typically consist of a fuse, explosives (including oxidizers, reducing agents, fuels, and special effects ingredients), an outer shell, and other auxiliary materials. When the fuse is lit, the internal explosives burn or explode in a designed manner, producing a variety of dazzling effects such as sparks, sounds, and patterns.

[0003] Fireworks quality refers to the comprehensive characteristics of fireworks in terms of safety, performance, and environmental friendliness. Ensuring product quality and safety is paramount in the fireworks manufacturing industry. However, existing fireworks quality testing methods have certain limitations, particularly in the testing of propellant density. Traditionally, propellant density measurement relies on manual weighing and volume calculation. This method is not only inefficient but also prone to human error, making it difficult to guarantee data accuracy and consistency. Furthermore, in some cases, increasing testing speed may sacrifice accuracy, which directly affects the safety performance of fireworks and could potentially lead to safety hazards.

[0004] Therefore, it is necessary to design a fireworks quality testing and classification device to solve the above-mentioned technical problems. Utility Model Content

[0006] The technical implementation scheme of this utility model is as follows: A fireworks quality detection and classification device includes a frame, a first transmission group, a second transmission group, a microwave sensor, a controller, cylinders, a moving plate, a support frame, a motor, gears, a gear ring, a transfer frame, and a third transmission group. The first transmission group is fixedly connected to one side of the frame and is set in an inclined state, i.e., the first transmission group is lower on the left and higher on the right. The second transmission group is symmetrically fixedly connected to both sides of the middle of the frame. A microwave sensor is fixedly connected to the top of the frame. A controller is fixedly connected to the other side of the frame. Cylinders are symmetrically fixedly connected to both sides of the bottom of the frame.

The top of the third transmission group is flush with the top of the second transmission group, and the third transmission group is located between the two second transmission groups with a certain gap between them. The first transmission group, the second transmission group, the microwave sensor, the cylinder, the motor, and the third transmission group are all electrically connected to the controller.

[0007] More preferably, it also includes a fixing plate and a fourth transmission group. The fixing plates are symmetrically fixed to the front side of the frame, and the fourth transmission group is fixed between the two fixing plates. The fourth transmission group is electrically connected to the controller.

[0008] More preferably, it also includes support blocks, guide plates and springs. Two support blocks are symmetrically fixed to the top two sides of the first transmission group. A guide plate is slidably connected between the two support blocks on the same side. The two guide plates are symmetrically distributed, and the right side of the two guide plates is a wide end, forming an flared shape. Each guide plate is fixed to the two support blocks on the same side with a spring.

[0009] More preferably, it also includes guide seats, lighting lamps, lamp housings and levers. Two guide seats are symmetrically fixed to the top of the frame.

[0010] More preferably, both the gears and the gear rings are made of ceramic and coated with a silicon carbide coating.

[0011] More preferably, the lighting fixtures are powered by DC.

[0012] Compared with the prior art, the present invention has the following advantages: 1. The present invention uses the cooperation of the first transmission group and the second transmission group to transport the fireworks to the top of the third transmission group. The controller activates the microwave sensor to detect the density of the gunpowder inside the fireworks and judges whether the quality of the fireworks meets the standard value range based on the change in the amplitude of the displayed microwave signal, thereby achieving the effect of accurately detecting the quality of the fireworks.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: A fireworks quality testing and classification device, such as Figures 1-3 As shown, the system includes a frame 1, a first transmission group 2, a second transmission group 3, a microwave sensor 4, a controller 5, a cylinder 6, a moving plate 7, a support frame 8, a motor 9, a gear 10, a gear ring 11, an adapter frame 12, a third transmission group 13, a fixing plate 14, and a fourth transmission group 15. The first transmission group 2 is connected to the right side of the frame 1 by screws. The first transmission group 2 is set in an inclined state, that is, the left side of the first transmission group 2 is lower than the right side. The second transmission group 3 is symmetrically connected to the left and right sides of the middle of the frame 1 by screws. The second transmission group 3 is located at the first transmission group 1. On the left side of group 2, a microwave sensor 4 is mounted on the top of the frame 1 via screws. The microwave sensor 4 can perform non-contact detection and, compared to the traditional weighing method, can simultaneously obtain gunpowder density distribution information. A controller 5 is mounted on the front left side of the frame 1 via screws. Cylinders 6 are symmetrically mounted on the front and rear sides of the bottom of the frame 1 via screws. A moving plate 7 is keyed between the tops of the pistons of the two cylinders 6. A support frame 8 is connected to the bottom left side of the moving plate 7 via screws. A motor 9 is mounted on the middle of the support frame 8 via screws. A gear 10 is keyed to the output shaft of the motor 9. Gear 10... The top of the 0 is in close contact with the bottom of the movable plate 7. An adapter frame 12 is rotatably connected to the top of the movable plate 7. A gear ring 11 is keyed through the middle of the movable plate 7 at the bottom of the adapter frame 12. The top of the gear ring 11 is in close contact with the bottom of the movable plate 7, and the gear ring 11 meshes with the gear 10. The gear ring 11 is located to the right of the gear 10. Both the gear 10 and the gear ring 11 are made of ceramic and coated with silicon carbide, effectively preventing the metal gear 10 and gear ring 11 from interfering with the microwave field. A third transmission group 13 is connected between the left and right side walls of the adapter frame 12 by screws. The top of the third transmission group 13 is flush with the top of the second transmission group 3, and the third transmission group 13 is located between the two second transmission groups 3 with a certain gap between them. The front middle of the frame 1 is symmetrically connected to the fixing plate 14 by screws. The fourth transmission group 15 is connected to the middle of the two fixing plates 14 by screws. The fourth transmission group 15 is electrically connected to the controller 5. The first transmission group 2, the second transmission group 3, the microwave sensor 4, the cylinder 6, the motor 9, the third transmission group 13 and the fourth transmission group 15 are all electrically connected to the controller 5.

[0022] like Figure 1 , Figure 4 and Figure 5As shown, it also includes support blocks 16, guide plates 17, springs 18, guide seats 19, lighting lamps 20, lamp housings 21, and levers 22. Two support blocks 16 are symmetrically connected to the front and rear sides of the top of the first transmission group 2 via screws. Guide plates 17 are slidably connected between the two support blocks 16 on the same side. The two guide plates 17 are symmetrically distributed, and the right side of each guide plate 17 is a wide opening, forming a flared shape. Each guide plate 17 is welded to one of the two support blocks 16 on the same side via a spring 18. The inner top of the frame 1... The unit has two guide seats 19 connected symmetrically on the left and right by screws. A lighting lamp 20 is mechanically connected between each pair of guide seats 19 on the same side by a miniature screw. The lighting lamp 20 is powered by DC to avoid AC noise coupling. A lamp housing 21 is also rotatably connected between each pair of guide seats 19 on the same side. The lamp housing 21 is made of explosion-proof material. The lamp housing 21 and the lighting lamp 20 have the same shape, both being cylindrical. The lamp housing 21 partially encloses the lighting lamp 20. A lever 22 is bonded to one side of the lamp housing 21 by high-strength epoxy structural adhesive.

[0023] First, the staff places the device horizontally in the designated work area. When it is necessary to classify and test the fireworks for quality, the fireworks are first placed on the first transmission group 2. At this time, the fireworks are positioned between two guide plates 17 and limited by these two guide plates 17 to prevent the fireworks from shifting their position. Then, the controller 5 starts the first transmission group 2 and the second transmission group 3, and transports the fireworks to the left. When the fireworks are transported to the limit position of the first transmission group 2, they slide down to the top of the second transmission group 3 on the right and continue to be transported to the left until they are transported to the top of the third transmission group 13. At this time, the controller 5 shuts down the third transmission group 13 and simultaneously starts the microwave sensor 4. The microwave emitted by the microwave sensor 4 passes through the surface of the fireworks packaging and through the gunpowder. Due to the action of gunpowder media with different densities, the microwave propagation speed changes. That is, the uneven density of the gunpowder will cause the microwave signal amplitude to attenuate, thereby determining whether the density of the local area of ​​the gunpowder inside the fireworks meets the standard value range. For fireworks that pass the test, they will continue to be transported to the left until they reach the second transmission group on the left. The fireworks are placed on top of Group 3, and then manually removed by staff and placed in the designated integration area. If the fireworks are found to have loose or void defects (defective products), staff activate cylinder 6 and motor 9 via controller 5. At this time, the piston of cylinder 6 extends upward, pushing the moving plate 7, motor 9, third transmission group 13, and fireworks upward. During this process, the output shaft of motor 9 drives gear 10 to rotate 90° clockwise, and the gear ring 11 meshing with it rotates accordingly, causing the adapter 12, third transmission group 13, and fireworks as a whole to rotate 90° clockwise, so that the third transmission group 13 and the fourth transmission group 15 maintain the same conveying direction. When all components are pushed to the limit position, controller 5 stops cylinder 6. At this time, the top of the third transmission group 13 and the fourth transmission group 15 are level. The third transmission group 13 conveys the defective fireworks on its top forward to the top of the fourth transmission group 15, and then the fourth transmission group 15 continues to convey them forward. Finally, staff manually remove the defective fireworks and place them in the designated integration area.

[0024] After the defective fireworks are removed, controller 5 restarts cylinder 6 and motor 9. Cylinder 6 retracts downwards, driving motor 9, adapter frame 12, and third transmission group 13 back to their initial positions. During this process, motor 9 rotates in the opposite direction, its output shaft rotating 90° counterclockwise, driving gear 10 to rotate synchronously, restoring it to its original state. This continues until all components are reset, ensuring the top of the third transmission group 13 is once again aligned with the tops of the two second transmission groups 3, ready to receive the next fireworks to be tested. If the ambient light is insufficient, staff can turn on the lighting lamp 20 to provide illumination for clearer observation of the test results. When the lighting lamp 20 is no longer needed, the lamp housing 21 can be rotated by toggling lever 22 to cover the lighting lamp 20 and protect it from dust contamination.
