Problems solved by technology
Since the leak detection of milk powder tanks generally adopts the method of low-pressure leak detection, if the airtightness of the tank body is tested by the above-mentioned sealing cover, the pressure change value of the inner cavity of the milk powder tank is low, and when the damage on the milk powder tank When it is small, the pressure transmitter cannot detect the leak, and the leak detection accuracy of the entire milk powder tank leak detection device is low

The present invention discloses a milk powder can leakiness inspector, belonging to the technical field of precision leakiness inspectors. The leakiness inspector comprises a rotation rack, a liftingmechanism, a leakiness inspection device and an inflation device. The leakiness inspection device comprises an inflation rod penetrating a detection platform, a seal piece fixed at the bottom portionof the detection platform and butted against the top edge of a milk powder can and a filling piece clamped at the inflation rod and stretching into the milk powder can, the inflation rod has an inflation channel configured to perform air inflation to the inflation device, the filling piece has a leakage inspection channel communicating with the inflation channel and the inner cavity of the milk powder can, and the upper end of the inflation rod is connected in parallel with a pressure transmitter. The milk powder can leakiness inspector is high in leakage inspection precision of the milk powder can.
Description
technical field [0001] The invention relates to a leak detection machine for milk powder cans. Background technique [0002] In order to ensure the quality of the milk powder in the milk powder cans, it is necessary to perform a leak test on the milk powder cans storing the milk powder. At present, when detecting a tank body with an upper end opening, a sealing cover plate is used to seal the upper opening of the tank body, and an inflator is used to inflate the tank body, so that the air pressure in the inner cavity of the tank increases, and the air pressure is transmitted through the pressure transmitter. Measure the change in air pressure inside a closed container. Since the leak detection of milk powder tanks generally adopts the method of low-pressure leak detection, if the airtightness of the tank body is tested by the above-mentioned sealing cover, the pressure change value of the inner cavity of the milk powder tank is low, and when the damage on the milk powder ta...
