Description

Technical Field

[0001] This utility model relates to the field of aluminum can production equipment technology, and more specifically to an aluminum can lid conveying and lifting mechanism. Background Technology

[0002] After transportation, can lid strips need to be broken down into individual strips before being sent to the lid feeder to unpack the paper bags and then to the can sealing machine. To prevent the can lid strips from unraveling, each layer of strips is usually wrapped together with a stretch film, with some strips embedded between the others. Therefore, the stretch film needs to be removed during unpacking. Current can lid strip conveying methods typically involve manual handling of the strips from one location to the lid feeder, which is inconvenient, time-consuming, labor-intensive, and results in low automation. To address this, the inventor proposes a can lid strip conveying and lifting mechanism. This mechanism uses a conveyor belt and a mechanical conveying arm to transport the can lid strips from the conveyor belt to a turntable, facilitating the unpacking of paper bags and ultimately delivering them to the can sealing machine. This achieves automated production of can lids, improving production efficiency and automation levels for enterprises.

[0003] To achieve rapid unstacking of can lid strips and improve production efficiency and automation, Chinese Patent (Authorization Announcement No.: CN219620275U) discloses an unstacking device for can lid strip stacks. This utility model includes: a frame, a lifting assembly, and a film-clamping assembly, a pushing assembly, and a pulling assembly mounted on the frame. The lifting assembly has a lifting plate and a first lifting drive component. The lifting plate carries the can lid strip stack, and the first lifting drive component is adapted to drive the lifting plate to move up and down between a feeding position and a working position. The film-clamping assembly has a film-winding part and a film-clamping part. The film-clamping part is adapted to clamp the winding tape on the uppermost can lid strip of the can lid stack, and the film-winding part is adapted to wind up the winding tape when the uppermost can lid strip is removed. The pulling assembly has a clamp and a first moving drive component. The clamp is adapted to receive and clamp the uppermost can lid strip, and the first moving drive component is adapted to drive the clamp to move and remove the uppermost can lid strip from the can lid stack. The pushing assembly is adapted to push the uppermost can lid strip into the clamp. This invention can quickly unpack stacked can lid strips, improving unpacking efficiency.

[0004] The solution still has some shortcomings in application. After the can lid strips are unpacked, they form individual can lid strips. Each lid strip needs to be sent to the lid feeding machine for paper bag separation. Therefore, each lid strip needs to be transported from the conveyor belt to the lid feeding machine for paper bag separation. Batch conveying is not conducive to the paper bag separation operation. The structure of the lid strip conveying device needs to be improved to overcome the above-mentioned problems, so as to realize automatic conveying, facilitate paper bag separation, effectively realize the automation level of can lids and improve production efficiency.
