Abstract

The invention relates to the technical field of five-layer co-extrusion infusion production equipment, and particularly discloses a five-layer co-extrusion infusion film detection device. The detection device comprises a casing, wherein a mounting base is fixedly arranged in the casing; an assembly groove is formed in the mounting base; a fixing shaft is fixedly arranged in the assembly groove; a first bearing is fixedly arranged on the outer side of the fixing shaft; a turntable is fixedly arranged on the outer side of the first bearing; meshing teeth are fixedly arranged on the outer side of the turntable; and air holes are formed in the turntable. The five-layer co-extrusion infusion film and the detection method thereof have the advantage of improving the production efficiency and solve the problems that a five-layer co-extrusion infusion film bag is commonly used for loading a liquid medicine in the medical field, the quality of a five-layer co-extrusion infusion film bag can be directly impacted by the sealing performance of the five-layer co-extrusion infusion film bag in the production process of the five-layer co-extrusion infusion film bag, and leakage of the liquid medicine loaded inside the five-layer co-extrusion infusion film bag can happen when the sealing performance and extrusion resistance of the five-layer co-extrusion infusion film bag are not standard.
