Abstract
This utility model relates to the field of inflatable packaging leak detection technology, and discloses an automatic gas leakage detection device for inflatable packaging, including a handling mechanism, a conveying mechanism, and a detection unit. The conveying mechanism includes an infeed conveyor belt, an outfeed conveyor belt, and a rejection conveyor belt. The handling mechanism picks up packaged products from the infeed conveyor belt and moves them to the detection unit for detection. Furthermore, the handling mechanism picks up packaged products that have completed detection in the detection unit and moves them to the outfeed conveyor belt or the rejection conveyor belt based on the detection results. This utility model utilizes a robotic arm to place packaged products from the conveyor belt into a small, sealed detection chamber formed by a cylinder-driven upper pressure plate and a detection base. Pressure is applied to the packaged products by a bag-pressing cylinder, eliminating the need for any manual operation steps, thus improving the degree of automation and accelerating the detection speed.
