Description

Technical Field

[0001] The utility model belongs to the technical field of film detection, and in particular relates to an expansion mechanism and metallized film surface defect detection equipment. Background Art

[0003] In the prior art, the expansion plates are mainly pushed to slide by connecting rods, and multiple expansion plates are expanded at the center of the coiled material, thereby facilitating the detachment of the coiled material. After the coiled material is expanded, its own elastic potential energy will exert a vertical force on the expansion plates. At this time, although the coiled material is detached from the winding roller, the coiled material will hold the multiple expansion plates tightly, and the contact surfaces of the expansion plates and the coiled material are parallel to each other, making it difficult for the coiled material to detach from the expansion plates. If the expansion plates can be flipped toward the end of the winding roller to form a guiding surface of the umbrella surface, the above-mentioned defects can be alleviated to a certain extent.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0015] 2. By setting the second connecting block and the first connecting block, when the second connecting block pushes the second connecting rod to flip, the second connecting rod pushes the corresponding push plate out of the flipping channel of the winding roller.
