[0036] It should be noted that the high cover correction device provided in this embodiment can be placed in the rear section of the conveyor line of the packaging capping machine. When the on-site operator sees that the high cover of the can body is not aligned, the can body on the conveyor line is removed, and the can body part is inserted into the clamping cavity of the can body locking mechanism 100. The can body is locked and fixed by the can body locking mechanism 100, and the high cover part is locked and clamped by the handheld correction mechanism 200. The high cover is driven to rotate relative to the can body through the action of external force, thereby achieving the alignment and buckling of the can body and the high cover, reducing the loss of the high cover, and reducing the labor intensity of manually disassembling the high cover and then reinstalling the new high cover. The device is suitable for promotion and application.
