The sixth station mechanism is a mechanism for forming a positioning ring and rolling the top edge of the metal can body outward. The first station mechanism is composed of a first station lifting mechanism at the bottom and a first station rolling and flanging mechanism at the top. The second station mechanism is composed of a second station lifting mechanism at the bottom and a bottom loading mechanism at the top. The third station mechanism is composed of a metal can body flipping mechanism. The fourth station mechanism is composed of a fourth station lifting mechanism at the bottom and a cone expansion mechanism at the top.

The sixth station mechanism is composed of a sixth station lifting mechanism at the bottom, a limiting ring forming mechanism at the top, and a sixth station rolling and flanging mechanism at the top. However, this solution can only produce the body of a metal packaging can and cannot complete the entire process of producing a metal packaging can in one go. In addition, the equipment configuration is not very complete, which affects production efficiency and product quality.

The system consists of a first workstation, a second workstation that cuts the metal strip into a lifting handle and forms the first bend at the end of the lifting handle, and a third workstation that performs shaping and stamping on the lifting handle except for the end. The metal packaging can body conveying mechanism and the metal handle production mechanism intersect at the third workstation. The capping mechanism is located above the metal packaging can body installation position at the third workstation. Two rivet hammer mechanisms are located on either side of the metal packaging can body installation position at the third workstation, with their rivet hammers facing the first bend at the end of the lifting handle. However, this solution only allows for the production of metal handles and their installation on the metal packaging can body; it cannot complete the entire metal packaging can production process in one go.

The fully automatic high-speed full-process production line for metal packaging cans according to claim 1 or 2, characterized in that The third station mechanism is provided with a clamping mechanism for clamping the metal can body and a driving mechanism for driving the clamping mechanism to turn over.

5. The fully automatic high-speed production line for metal packaging cans according to claim 1 or 2, characterized in that The fourth station mechanism and the seventh station mechanism are both provided with a plurality of expansion templates longitudinally arranged in a circle and an expansion drive mechanism for driving the expansion templates to expand outward or contract inward.

6. The fully automatic high-speed full-process production line for metal packaging cans according to claim 1 or 2, characterized in that The eighth workstation mechanism is provided with a double-head spot welding mechanism and a handle ear one-by-one conveying mechanism.

7. The fully automatic high-speed full-process production line for metal packaging cans according to claim 1 or 2, characterized in that The ninth workstation mechanism is provided with a metal handle making mechanism and a riveting hammer mechanism for installing the metal handle into the handle ear.

8. The fully automatic high-speed production line for metal packaging cans according to claim 1 or 2, characterized in that The tenth station mechanism is provided with a coating head, a coating head driving mechanism and an anti-rust paint liquid supply mechanism.

9. The fully automatic high-speed full-process production line for metal packaging cans according to claim 1 or 2, characterized in that The first station mechanism is provided with a local diameter reduction rolling mechanism for the metal can body, which uses a multi-roller rolling mechanism to progressively roll the portion of the metal can body to be reduced in diameter, thereby reducing the local diameter of the metal can body.
