[0023] The specific operation is as follows: when the first cylinder 714 and the second cylinder 716 retract inward or extend outward, the first sliding pin 708 at the front end of the first movable plate 713 and the third sliding pin 710 at the rear end of the second movable plate 715 will respectively drive the first swing arm 704 and the third swing arm 706 to rotate, causing the rotating plate 703, the second swing arm 705, and the fourth swing arm 707 to rotate, causing the first sliding pin 708, the second sliding pin 709, the third sliding pin 710, and the fourth sliding pin 711 to slide in the sliding groove at the bottom of the shell 701 toward or away from the pressure plate 718, thereby meeting the sealing needs of metal cans of different sizes.

[0024] In summary, when the adjustable capping mechanism is used, the position of the spinning cam 712 is first adjusted according to the size of the metal can body, that is, the first cylinder 714 and the second cylinder 716 are controlled to retract inward, and the first movable plate 713 and the second movable plate 715 are respectively driven to retract a certain length by the first cylinder 714 and the second cylinder 716, and the first sliding pin 708 at the front end of the first movable plate 713 and the third sliding pin 710 at the rear end of the second movable plate 715 respectively drive the first swing arm 704 and the third swing arm 706 to rotate, so that the rotating plate 703, the second swing arm 705 and the fourth swing arm 707 rotate, causing the first sliding pin 708, the second sliding pin 709, the third sliding pin 710 and the fourth sliding pin 711 to slide in the sliding groove at the bottom of the shell 701 toward the pressing plate 718 until the distance between the two symmetrically distributed spinning cams 712 coincides with the outer diameter of the metal can body;

[0025] Then, the metal can body to be sealed is fixed with the clamp 4, and the can cover is placed on the can mouth of the metal can body. The clamp 4 is driven by the lifting cylinder 3 to lift the metal can body until the pressing plate 718 presses the can cover into the can mouth.

[0026] At this time, the spinning cam 712 abuts against the outer edge of the tank cover, and the driving motor 5 drives the driving shaft 6 and the adjusting assembly 7 to rotate, and the spinning cam 712 rotates along the periphery of the tank cover, which can realize that the spinning cam 712 presses the tank cover and wraps the outer edge of the tank cover on the outer edge of the metal tank body at the tank mouth. In this way, the tightness between the metal tank body and the tank cover is improved through the wrap-around sealing, ensuring the sealing effect.
