Description

Technical Field

[0001] This utility model relates to the field of automatic production equipment technology, specifically a dual-station bottle sealing tester. Background Technology

[0002] Plastic bottles are a common type of container in daily life, used for the outer packaging of food, chemical, and pharmaceutical products. Due to the special nature of their use, it is necessary to ensure that the sealing performance of plastic bottles meets the standard requirements. This requires the use of plastic bottle sealing testers to test and inspect all plastic bottles. Currently, many still rely on manual handling of the bottle body and placing the leak test head at the bottle mouth for individual testing, which is inefficient. How to efficiently detect plastic products with these quality problems is an urgent problem that needs to be solved by those skilled in the art. Utility Model Content

A collection box can be provided at the discharge opening 303 to collect defective products.

[0032] Workflow: The vacuum conveyor belt 2 is started to adsorb and transport the bottle. When the bottle is transported to the bottom of the detection component 10, the gas injection block 1003-2 is pressed against the bottle mouth. The bottle to be inspected is filled with air by the external gas injection device. At the same time, the air pressure sensor inside the gas injection block 1003-2 detects the air pressure inside the bottle and compares the detected value with the standard value. If the test is unqualified, the first pusher component 5 and / or the second pusher component 6 are used to push the defective product outward. The qualified product is transported to other processing stations by the vacuum conveyor belt 2.

[0033] Compared with the prior art, the dual-station bottle sealing tester of this application adopts a dual-station automatic detection and automatic unloading production mode for defective products. It has a high degree of automation, high detection efficiency, and a production capacity of up to 10,000 per hour. This application uses a vacuum conveyor belt structure to realize automatic conveying of bottles, ensuring that the transmission process of bottles is stable and that each bottle enters the test component with a uniform posture and precise position, thereby improving the reliability of test results.
