Description

Technical Field

[0001] The utility model relates to the technical field of co-extruded film production and processing, in particular to a surface scratch detection device for a co-extruded film. Background Art

[0002] Co-extruded film refers to a plastic film with two or more layers made from PE, PA, EVOH and other plastic particles through a co-extrusion casting process. It is widely used in the packaging and food industries because of its good stretchability, air barrier, moisture resistance, environmental protection and good surface brightness. The surface scratch defects of existing co-extruded films can be detected through defect imaging and system processing. The difficulties in detection are: 1. The product size is limited and cannot be applied to larger roll film materials (the detection width requires 2.5m), and one camera cannot correspond to a 2.5m detection field of view; 2. The imaging effect of line scan cameras on surface scratches of film products is average; 3. The travel speed of roll products is relatively fast (MAX60m / min), and the existing detection structure has the problem of too high missed detection rate; 4. Customers require that the size of the whole machine should be as small as possible under the premise of ensuring the detection quality and detection speed, resulting in the existing layout being unable to meet customer requirements, and thus a surface scratch detection device is urgently needed.
