Description

Technical Field

[0001] This utility model relates to the field of small-bucket air-injection and water-spraying leak detection technology, and in particular to a small-bucket air-injection and water-spraying leak detection device. Background Technology

[0002] In industries such as food, chemicals, and daily necessities, small containers (such as plastic and metal drums) are common packaging containers, and their airtightness directly affects the storage safety and transportation quality of the contents. If small containers have even minor cracks or loose connections, leakage can occur, leading to spoilage, contamination, economic losses, and even safety hazards. Existing methods for testing the airtightness of small containers have many shortcomings.

[0003] Existing leak detection devices suffer from low efficiency due to manual inspection. Traditional methods, such as water injection or soaking for seepage, require manual handling and emptying, which is time-consuming and labor-intensive, and difficult to adapt to the testing needs of mass production. Furthermore, their detection accuracy is insufficient; for minute leaks, manual visual inspection is prone to misses, especially in concealed areas such as weld seams and threaded openings, which are difficult to detect with simple water injection. Their applicability is also limited; different sizes and materials of small barrels (such as different heights and diameters) require adjustments to the fixing and sealing structure of the detection device. Traditional devices lack flexible adaptability, necessitating frequent adjustments when changing the target, thus affecting detection efficiency. These problems make small barrel sealing testing a weak link in the production process. Therefore, we propose a small barrel air-injection and water-spray leak detection device. Utility Model Content

[0004] The purpose of this invention is to provide a small-barrel air-injection and water-spraying leak detection device, which solves the existing problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Preferably, a motor is fixedly installed on the right side of the bucket placement and fixing frame, a lead screw is fixedly installed on the output end of the motor, a movable plate is threaded on the outer side of the lead screw, two fixed rods are fixedly installed on the inner side of the bucket placement and fixing frame, and the movable plate is slidably installed on the outer side of the fixed rods.

[0008] Preferably, an electric telescopic rod is fixedly installed on the right side of the movable plate, and a small bucket clamping plate is fixedly installed at the output end of the electric telescopic rod. Rubber pads are fixedly installed on one side of both the small bucket clamping plate and the test abutment plate.

[0009] Preferably, a fixing plate is fixedly installed on the top of the bucket placement and fixing frame, an electric slide rail is fixedly installed on the top of the fixing plate, two electric sliders are slidably installed on the top of the electric slide rail, an auxiliary frame is fixedly installed on the top of the electric sliders, and a bucket height adjustment roller is rotatably installed on the inner side of the auxiliary frame.

[0010] Preferably, a water pump is fixedly installed on the top of the water storage tank, and an air pump is fixedly installed on the top of the air injection tank. Both the water pump and the air pump are fixedly installed with connecting pipes on their tops, and one end of the connecting pipe is fixedly installed on the left side of the test contact plate.

[0011] Preferably, the inner side of the test contact plate is provided with a connecting groove, and the connecting pipe and the central test through hole are both connected to the connecting groove.

[0012] Preferably, a one-way valve is fixedly installed on the outside of each connecting pipe, and a drainage groove is provided at the bottom of the small bucket placement bracket.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This utility model discloses a small bucket air-injection and water-spray leak detection device. A motor-driven screw on the bucket placement and fixing bracket moves a movable plate, which, in conjunction with an electric telescopic rod, pushes the bucket against a clamping plate, automatically pushing the bucket to the test abutment plate and fixing it in place, eliminating the need for manual handling and alignment. A water pump and an air pump automatically complete the water and air injection operations through connecting pipes. Compared to traditional manual water injection and observation, this significantly shortens the testing time for a single bucket, adapting to the testing needs of mass production and solving the problem of low manual efficiency. The air injection tank injects gas into the bucket through a central test through-hole, creating positive pressure inside the bucket. Simultaneously, a water tank sprays water onto the bucket surface through the same channel. Tiny leaks will generate bubbles due to the air pressure, facilitating rapid identification. Rubber gaskets between the test abutment plate and the bucket clamping plate ensure a seal, preventing gas and water leaks from interfering with the detection. This device is particularly effective in accurately detecting minute gaps in hidden areas such as bucket welds and bucket opening threads, reducing missed detections.

[0015] This utility model discloses a small-barrel air-injection and water-spray leak detection device. An electric slider on an electric slide rail moves an auxiliary frame, and the spacing of the rollers can be adjusted according to the barrel diameter and height to accommodate barrels of different sizes. The sliding distance of the moving plate along the fixed rod is adjustable, and combined with the extension length of the electric telescopic rod, it can accommodate barrels of different heights, eliminating the need for frequent replacement of the fixed structure and improving the detection efficiency for various small barrels. The control panel integrates the operation of the motor, electric telescopic rod, water pump, and air pump, simplifying the operation process. A one-way valve ensures unidirectional flow of water and air, preventing backflow from affecting the detection. A drainage trough promptly discharges wastewater after testing, reducing manual cleaning work and lowering reliance on operator skills. Attached Figure Description
