Description

Packaging cover surface detection equipment Technical Field The invention relates to the technical field of detection equipment, in particular to packaging cover surface detection equipment. Background The packaging cover on the food packaging box is processed through an injection molding process, but when the gas in a melt or a cavity cannot be effectively discharged during processing, or insufficient material flow is not supplied during cooling shrinkage of the melt, bubbles are generated in the formed packaging cover, when the packaging cover with bubbles of a certain size or a certain number of bubbles is used, if the bubbles are broken to form tiny gaps, or the bubbles cause uneven thickness of the packaging cover, the tightness of the packaging cover is reduced, external oxygen, moisture and microorganisms are easy to invade, and the oxidative deterioration of the food is accelerated. At present, the integrated industrial camera bubble detection unit of the Chinese patent publication with the publication number of CN220271190U comprises a glass detection platform, an industrial camera component, a light source component, a glue inlet flow dividing component, a reversing valve body component and a protective cover component, and can be used for colloid detection of a single flow passage, and can also be used for detection of a plurality of groups of flow dividing detection passages by expanding the flow dividing flow passage and using a plurality of groups of industrial cameras and glass detection platforms.
