Description

Technical Field

[0001] The present application relates to the field of production and manufacturing technology, and in particular to a sealing device for aluminum alloy can lids that are adaptable to various shapes. Background Art

[0002] The crimping sealing is achieved by applying force to the crimping sealing part of the metal can by the crimping roller. The pre-crimped edge strip will bend due to the extrusion, forming a mutual crimping structure. After that, the pre-crimped edge strip of the metal can is rolled a second time, and the double crimping is completed through the elastic-plastic deformation of the metal sheet material. Finally, the edge of the can body and the can cover are bent and hooked to form a crimping seam with two layers of can body and three layers of can cover.

[0003] The sealing trajectory of special-shaped cans is more complex than that of round cans. During the sealing process, the sealing roller needs to perform three movements, including circumferential rotation, radial feeding, and contouring according to the outer contour of the special-shaped can. The contouring movement is usually achieved through a forming cam that matches the shape of the can body. In order to adapt to the complex trajectory of the special-shaped can, the existing forming cam mainly uses a conjugate cam to fit the contour of the special-shaped can for smooth movement. However, for the conjugate cam of a single special-shaped can, there are problems such as high preparation cost, complicated production process, and inconvenient replacement and adjustment. In addition, a single conjugate cam can only adapt to a single special-shaped can with poor adaptability, which limits the development of special-shaped can types.
