Description

Technical Field

[0001] This utility model relates to the technical field of kettle leak detection, and in particular to a leak detection tooling for kettle production. Background Technology

[0002] A kettle is a container for holding water. It can refer to a metal kettle used for boiling water or a portable drinking water bottle. Its materials are mainly divided into five categories: plastic, stainless steel, aluminum alloy, ceramic, and other materials. It can be heated by electricity or directly by fire. After the kettle is manufactured, staff need to conduct an airtightness test to prevent the kettle from leaking. Traditional methods for testing the airtightness of kettles rely on manual filling with water followed by prolonged observation, or subjective judgment of leakage using methods such as water immersion or soapy water spraying. These methods suffer from drawbacks such as low efficiency, long testing cycles, difficulty in detecting minute leaks, and significant interference from human factors (such as visual error), and cannot quantitatively measure the leakage rate. To address these issues, this application provides a leak detection fixture for kettle production. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a leak detection tool for kettle production, which solves the technical problems of slow water filling detection process and insufficient detection precision, thereby achieving the goal of improving detection precision and efficiency.

[0006] Preferably, the air outlets of two of the three tracheas are connected to the first airbag and the second airbag, respectively, and the air outlets of the remaining tracheas extend to the outer side of the bottom end of the extension support frame.

[0007] Preferably, clamping cylinders are installed on both sides of the top of the conveyor frame, and storage slots are fixedly connected to the extension ends of the clamping cylinders. Clamping rods are rotatably connected to both ends of the inner side of the storage slots, and clamping belts are sleeved on the two clamping rods located inside the same storage slot.

[0009] Preferably, the conveyor frame is equipped with a drive motor for use.

[0010] By means of the above technical solution, this utility model provides a leak detection tooling for kettle production, which has at least the following beneficial effects: 1. Due to the setting of the automated inflation detection structure, this utility model replaces the traditional manual water filling and static observation method, realizes rapid sealing and dynamic air pressure monitoring, significantly shortens the detection cycle and improves detection efficiency; at the same time, it accurately captures minute leaks, avoids human visual inspection errors, improves leak detection precision, and ensures that the product's airtightness meets the standards.

[0015] 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.

[0016] Example 1

[0017] Traditional methods for testing the airtightness of kettles rely on manually filling them with water and then observing them for an extended period, or on subjective judgments such as water immersion or soapy water spraying. These methods are inefficient, have long testing cycles, struggle to detect minute leaks, are susceptible to human error (such as visual inspection), and cannot quantitatively determine the leakage rate. Please refer to [reference needed]. Figures 1-5 This embodiment provides a leak detection fixture for kettle production, which solves the technical problems of slow water filling detection process and insufficient detection precision. The device includes a conveyor frame 1 as a supporting base, a support frame 2 at the top of the conveyor frame 1, a pusher frame 3 slidably connected to the top of the support frame 2, a pusher cylinder 4 installed at the top of the support frame 2 via a base, an air filling pump 5 installed on one side of the top of the support frame 2 via a base, three electromagnetic valves 6 connected to the air outlet of the air filling pump 5, and air pipes 8 connected to the air outlets of the electromagnetic valves 6. An extension support tube frame 7 is fixedly connected to the bottom of the pusher frame 3, and a first airbag 9 and a second airbag 10 are respectively installed on the lower outer side of the extension support tube frame 7.

[0018] In order to observe the expansion of the first airbag 9 and the second airbag 10 during testing, and to ensure that the first airbag 9 and the second airbag 10 can fit tightly against the inner wall of the water bottle when it is used for different sizes of water bottles, an observation camera 11 is installed on the outer surface of the extension support tube 7 between the first airbag 9 and the second airbag 10.

[0019] In order to inflate the first airbag 9, the second airbag 10, and the inside of the water bottle, two of the three air tubes 8 are connected to the first airbag 9 and the second airbag 10 respectively, and the air tube 8 extends to the outside of the bottom end of the extension support tube frame 7.

[0020] During operation, the operator places the kettles to be tested at equal intervals on the top of the conveyor frame 1. As the conveyor moves, once the kettles are below the testing components, the operator activates the push cylinder 4. The push cylinder 4 pulls the push frame 3 downwards, which in turn moves the connected extension support tube 7 downwards until its end extends into the kettle. The operator then sequentially activates three solenoid valves 6, thereby controlling the three air pipes 8 to inflate the first airbag 9, the second airbag 10, and the inside of the kettle. During inflation, the observation camera 11 can fully observe the first airbag 9. The expansion of the second airbag 10 allows for precise sealing of kettles of different sizes. After inflation, the outer sides of the first airbag 9 and the second airbag 10 can completely fit against the inner wall of the kettle, thus sealing the opening of the kettle. As the air tube 8 extending from the bottom of the extension support tube 7 continuously inflates into the kettle, the air pump stops inflating once the kettle is full. Subsequently, the air pressure sensor installed at the bottom of the extension support tube 7 monitors the air pressure change. Since the kettle is in a closed state at this time, the air pressure returned by the air pressure sensor will not change when inflation stops. If there is a change, it is determined that the kettle's sealing effect is not good.

[0021] Example 2

[0022] Based on Example 1, which solved the technical problems of slow water filling detection and insufficient detection precision, Example 1 still has the problem that the clamping component cannot clamp and fix water bottles of different sizes. Figures 1-5 As shown, the specific implementation process is as follows: In order to clamp the conveyed kettles and to clamp kettles of different sizes, clamping cylinders 12 are installed on both sides of the top of the conveyor frame 1. The extension ends of the clamping cylinders 12 are fixedly connected to the storage slots 13. The two ends of the inner side of the storage slots 13 are rotatably connected to clamping rods 14. Clamping belts 15 are sleeved on the two clamping rods 14 located inside the same storage slot 13. A drive motor for use is installed on the conveyor frame 1.

[0023] To ensure the clamping rod 14 has a rebound function and can adapt to kettles of different sizes, a return spring 16 is installed on the connecting shaft between the clamping rod 14 and the storage slot 13. One end of the return spring 16 is connected to the connecting shaft of the clamping rod 14, and the other end is connected to the storage slot 13.

[0024] During operation, while the kettle is being clamped and secured, the operator activates two clamping cylinders 12. At this time, the clamping cylinders 12 push the storage slot 13 connected to their extension ends, and the storage slot 13 drives the two clamping rods 14 connected to its inner side to move until the clamping belts 15 installed on the two clamping rods 14 contact the outside of the kettle. As the clamping continues, the two clamping rods 14 will retract inward, so that the clamping belts 15 can completely wrap around the outer wall of the kettle. This allows the clamping structure to adapt to kettles of different sizes.
