The utility model relates to a sealing mechanism of a sealing machine, which mainly has a container conveying mechanism, a pressing mechanism and a membrane material supplying mechanism. The power source of the container conveying mechanism is a DC brushless motor, and the distance relationship between the rotation of the DC brushless motor and the displacement mechanism of the container conveying mechanism and the movement of the container bearing can be calculated. Through design, the rotation of the DC brushless motor can be accurately controlled. When the displacement mechanism moves the vessel bearing, the vessel bearing can reach and stop at the default position automatically, and the design of fixed-point switch is exempted from the container conveying mechanism. The power source of the pressing mechanism is DC brushless motor, which can also be used to calculate the distance relationship between the movement of the driving mechanism in the pressing mechanism and the movement of the connecting hot-pressing die, as well as precisely control DC brushless motor. When the rotational speed makes the driving mechanism move, the hot-pressing die can also reach and stop at the default position automatically, which also eliminates the design of the up switch and down switch for the pressing mechanism.
