The basic principle of our vacuum detector: If the tank(bottle) vacuum degree is different in the body, Tank lid (bottle) caused by the shape of the deformation is also different, The machine with precision components detect tiny deformation of the lid, Data by computer automatically, Immediately analyze whether the products meet the requirements of vacuum degree, The vacuum degree did not meet the product immediately launched by the cylinder behind the conveyor line. So the device can dynamic on-line detection on the conveyor belt. And automatically picking after test did not reach the set of "vacuum" or "inner pressure" tank (bottle). The machine is suitable for two pieces of aluminum cans, 3-piece cans, glass bottles, and all the other combined with type of container. With a simple and efficient operation. Ts key components with German and Japanese products. For the domestic initiative, The only replace imported high-tech products, Over the years has been widely used in many beverage and cannery's factory.
