The basic principle of the vacuum detector produced by our company is: if the vacuum degree inside the can (bottle) is different,the appearance deformation of the can (bottle) cap is also different, the machine uses precise components for detection. After the data is automatically processed by the computer, it will be immediately analyzed if the product has reached the required vacuum degree. The product that has not reached the vacuum degree will be immediately pushed out of the conveying line by the rear cylinder. Therefore, the equipment can carry out dynamic online detection on the conveyor belt and automatically eliminate those cans (bottles) that haven’t reached the set “vacuum” or “internal pressure” after detection. The machine is suitable for two-piece aluminum cans, three-piece iron cans, glass bottles and other combined vessels. Its operation is simple and highly efficient. Its key components are made of German and Japanese products. As a first creation in the country, it is the only high-tech product that replaces imported ones.
