Description

Technical Field

[0001] This utility model relates to the field of can lid processing equipment, and in particular to a positioning device for can lid processing. Background Technology

[0002] Metal cans are an important type of packaging container in the packaging industry. Their main body consists of a can body and a can lid. Many can lids are stamped from a thin sheet of metal. The can lid has a sheet-like lid body with a hollow protrusion that bulges downward in the middle of the lid body. The hollow protrusion is cylindrical. The periphery of the lid body has a bulging edge that bulges downward. The shape of the bulging edge is consistent with the shape of the outer edge of the lid body. A capping device is required during the processing of metal can lids.

[0003] The existing publication number CN220717512U discloses a stamping die with a limiting structure for processing three-piece can lids, including a support base.
