Technical Field
[0001] This utility model relates to the technical field of ammonium perchlorate product testing equipment, and in particular to a ring-type leak detection device for ammonium perchlorate product packaging. Background Technology
[0002] Ammonium perchlorate is a white crystalline solid with deliquescent properties. It is a strong oxidizing agent. It can explode when mixed with reducing agents, organic matter, flammable materials such as sulfur, phosphorus, or metal powders. Contact with strong acids poses a risk of combustion and explosion. It is used in the manufacture of explosives and fireworks, and as an analytical reagent. Magnesium metal initiates the oxidation of aluminum, which in turn causes the decomposition of ammonium perchlorate, producing a large amount of gas used in rocket launches. It is also used in the manufacture of ammonium perchlorate explosives, engraving agents, and artificial hail suppressants. Ammonium perchlorate products are packaged in various ways, including woven bags and cartons, according to user requirements. After packaging, leak testing is required to ensure product safety.
[0003] The patent titled "A Leak Detection Device for Ammonium Perchlorate Product Packaging" (patent application number: 202120723692.8) discloses a leak detection device for ammonium perchlorate product packaging, including a first roller conveyor device, a second roller conveyor device above the conveying end of the first roller conveyor device, a conveyor belt device below the first roller conveyor device, a liftable pressure roller above the first roller conveyor device, a weighing plate below the first roller conveyor device, a weighing sensor at the bottom of the weighing plate, and a vertically arranged conveyor belt device on the side of the conveying end of the first roller conveyor device. A hanging rod is hinged to the conveying chain of the conveyor belt device, and the bottom of the hanging rod is fixedly connected to multiple support rods through a horizontal plate. This device can detect leaks in ammonium perchlorate product packaging with potential leakage points during pressure application, greatly reducing the labor intensity of workers and improving the accuracy of the leak detection process.
[0004] In the above case, during use, when the pressure roller squeezes the ammonium perchlorate product with a leak in the packaging, the ammonium perchlorate will leak out. Furthermore, due to the unpredictability of the leak point, if the leak occurs on the side of the packaging, the leaking ammonium perchlorate will be sprayed along the side of the packaging under the pressure of the roller, making it difficult for the leaked ammonium perchlorate to fall onto the top of the weighing plate, thus reducing the accuracy of the leak detection. Therefore, it is necessary to propose a surround-type leak detection device for ammonium perchlorate packaging to solve the above problems. Utility Model Content

[0023] 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.
[0024] This utility model provides, for example Figures 1-4 The illustrated leak detection device for ammonium perchlorate product packaging includes a conveyor frame 1. A detection assembly is located in the center of the conveyor frame 1. The detection assembly includes a sealing frame 2, a first electric push rod 4, a pressing plate 5, a weighing plate 6, and a second electric push rod 7. The inner side of the sealing frame 2 is fixedly connected to the outer side of the first electric push rod 4. The telescopic end of the first electric push rod 4 is fixedly connected to the side of the pressing plate 5. The telescopic end of the second electric push rod 7 is fixedly connected to the top of the sealing frame 2. The weighing plate 6 is located below the conveyor frame 1, and a weighing sensor is located at the bottom of the weighing plate 6. The weighing sensor facilitates the weight detection of the ammonium perchlorate product flowing onto the weighing plate 6.
[0025] Among them, the sealing frame 2 has slots 3 on both sides near the conveyor frame 1, and the slots 3 are engaged with the inner side of the top of the conveyor frame 1. The bottom of the conveyor frame 1 is fixedly connected to the support leg 18, and the inner side of the support leg 18 is fixedly connected to the support plate 19. The top of the support plate 19 is fixedly installed with the bottom of the weighing plate 6. The bottom of the conveyor frame 1 is fixedly connected to the guide plate 17, which is located above the weighing plate 6. The outside of the conveyor frame 1 is fixedly connected to the conveyor motor 20, and the outside of the output shaft of the conveyor motor 20 is fixedly connected to the conveyor roller 21. The outside of the conveyor roller 21 is connected to the conveyor belt 22. During leak detection of packaged ammonium perchlorate products, when the transported ammonium perchlorate product passes directly below the sealing frame 2, the conveyor motor 20 stops working, and the second electric push rod 7 moves the sealing frame 2 downward, so that the ammonium perchlorate product is located inside the sealing frame 2. Then, the first electric push rod 4 is opened to drive the extrusion plate 5 to extrude the ammonium perchlorate product. When the weighing sensor does not detect a change in the weight of the weighing plate 6, the weighing sensor will reset the first electric push rod 4 and the second electric push rod 7 through the controller, and stop clamping and extruding the packaged ammonium perchlorate product. Then, the conveyor motor 20 resumes rotation and transports the qualified ammonium perchlorate product through the conveyor belt 22.
[0026] Additionally, a movable assembly is provided on the top of the conveyor frame 1. This movable assembly includes a mounting frame 8, the bottom of which is fixedly connected to the top of the conveyor frame 1. A lead screw 9 is rotatably connected inside the mounting frame 8. One end of the lead screw 9 is fixedly connected to a forward / reverse motor 10. The exterior of the forward / reverse motor 10 is fixedly connected to the exterior of the mounting frame 8. A threaded block 11 is threaded onto the exterior of the lead screw 9, and the threaded block 11 has a threaded hole that engages with the lead screw 9. A positioning rod 12 is slidably connected inside the threaded block 11, the end of which is fixedly connected to the side of the mounting frame 8. The bottom of the threaded block 11 is fixedly connected to the top of the second electric push rod 7. The signal output terminal of the weighing sensor is electrically connected to the input terminal of the controller. The control signal output terminal of the controller is electrically connected to the control terminals of the first electric push rod 4, the second electric push rod 7, the forward / reverse motor 10, and the conveyor motor 20, respectively. When the first electric push rod 4 drives the extrusion plate 5 to extrude the ammonium perchlorate product with a leak, the product will leak out of the packaging. At this time, the sealing frame 2 will block and guide the extruded ammonium perchlorate product, so that the product can only flow into the weighing plate 6 through the guide plate 17 from the inside of the conveyor frame 1 and the side of the conveyor belt 22. The weighing sensor will sense the change in the weight of the weighing plate 6, which will cause the sealing frame 2 to move upward through the second electric push rod 7. Then, the forward and reverse motor 10 will be turned on, and the lead screw 9 will drive the lead block 11 to move. The lead block 11 will drive the sealing frame 2 to move through the second electric push rod 7. When the sealing frame 2 moves out of the top of the conveyor frame 1, the first electric push rod 4 will reset and no longer clamp the ammonium perchlorate product. This allows the ammonium perchlorate product with a leak to move out of the top of the conveyor frame 1, making it easier to process the product and improving the accuracy of leak detection.
[0027] Finally, a transmission rod 13 is fixedly connected to the outside of the wire block 11. A cleaning block 14 is fixedly connected to one end of the transmission rod 13. A first limiting plate 15 is slidably connected to the outside of the transmission rod 13. The top of the first limiting plate 15 is fixedly connected to the bottom of the conveyor frame 1. A second limiting plate 16 is slidably connected to the outside of the transmission rod 13. The bottom of the second limiting plate 16 is fixedly connected to the top of the mounting frame 8. When the forward and reverse motors 10 drive the wire block 11 to remove the ammonium perchlorate product with a leaking package, the wire block 11 will drive the cleaning block 14 to move through the transmission rod 13, which facilitates the cleaning of the ammonium perchlorate product falling onto the surface of the counterweight plate 6, thus improving the efficiency of leak detection of ammonium perchlorate products.
[0028] Working principle: When the first electric push rod 4 drives the extrusion plate 5 to extrude the ammonium perchlorate product with leakage points in the packaging, the ammonium perchlorate product with leakage points will leak out of the packaging through the extrusion. At this time, the sealing frame 2 will block and guide the extruded ammonium perchlorate product, so that the ammonium perchlorate product can only flow into the weighing plate 6 from the inside of the conveyor frame 1 and the side of the conveyor belt 22 through the guide plate 17. At this time, the weighing sensor will sense the change in weight of the weighing plate 6, which will drive the sealing frame 2 to move upward through the second electric push rod 7. Then, the forward and reverse motor 10 will be turned on, and the lead screw 9 will drive the lead block 11 to move. When the wire block 11 moves, it drives the sealing frame 2 to move via the second electric push rod 7. When the sealing frame 2 moves out of the top of the conveyor frame 1, the first electric push rod 4 resets and stops clamping the ammonium perchlorate product. This allows the ammonium perchlorate product with leaks to move out of the top of the conveyor frame 1, facilitating subsequent processing of the ammonium perchlorate product and improving the accuracy of leak detection. At the same time, the wire block 11 drives the cleaning block 14 to move via the transmission rod 13, facilitating the cleaning of the ammonium perchlorate product falling onto the surface of the symmetrical weighing plate 6 and improving the efficiency of leak detection.
