[0013] Beneficial Effects

[0014] The utility model provides a sealing machine for food packaging, which has the following beneficial effects:

[0015] (1) A sealing machine for food packaging. During use, the position of the packaging bag to be sealed is placed on the upper wall of the lower heating plate, and the two heating plates are heated. Then, the movable pressing plate is lowered through the height adjustment mechanism so that the two heating plates contact each other to complete the sealing operation. Then, the movable pressing plate continues to move downward, and the lower heating plate is forced to move downward. The first spring is compressed, and the cutting blade cuts the sealing part of the packaging bag. In this way, the edge of the packaging bag is cut, which is convenient for cutting the packaging bag later. This method of sealing and cutting at the same time does not require the user to perform the cutting process separately, which is convenient for the user to use.

[0016] (2) A sealing machine for food packaging. During use, the utility model turns on the driving motor, and the output end of the driving motor drives the cam plate to rotate. The end of the cam plate away from the axis will squeeze the movable pressure plate to move downward, and the second spring begins to stretch. As the cam plate rotates, the outer wall of the principle axis of the cam plate will move away from the movable pressure plate, and the second spring begins to shrink. Finally, the movable pressure plate returns to its original state. In addition, when the packaging bag is placed on the upper wall of the lower heating plate, the right outer wall of the packaging bag and the left wall of the limit baffle are fitted together, so that the packaging bag and the right wall of the lower heating plate can be aligned, which is convenient for use of the device.
