Abstract
The invention provides a guide detection device for an inflated packing bag. The guide detection device comprises a controller, a rack, a conveyer belt arranged on the rack, a pinch roller positioned above the conveyer belt and a sensor for detecting stress conditions of the pinch roller, wherein a distance exists between the conveyer belt and the pinch roller, and the sensor is connected with the controller. The invention further provides a guide detection method for the inflated packing bag. The guide detection method mainly includes that the inflated packing bag to be detected is transmitted below the pinch roller under the guide of the conveyer belt, if the inflated packing bag to be detected leaks air, the pinch roller is not under stress, and if the inflated packing bag to be detected dose not leak air, the pinch roller is under stress and lifted; the sensor detects the stress conditions of the pinch roller and sends signals to the controller; and the controller determines the stress conditions of the pinch roller according to the signals in the last step and sends command signals. The guide detection device has the advantages of simple structure, low processing cost, high production efficiency and the like; and missing direction and mistaken direction for leaky inflated packing bag are avoided.
