Protrusions are provided at both ends of the upper end of the limiting block. The limiting block is slidably connected to the guide groove and the sliding groove through the protrusions respectively. The knob passes through the sliding groove and is threadedly connected to the inner wall of the protrusion located at the top of the limiting block. There are two limiting blocks.

[0008] As a preferred technical solution of the utility model, a bracket is fixedly connected to the top of the machine, the bracket is L-shaped, and a driving cylinder is fixedly installed on one side of the top of the bracket.

[0009] As a preferred technical solution of the utility model, the output end of the driving cylinder passes through the bracket and is fixedly connected with an electric heating plate.

[0010] As a preferred technical solution of the utility model, a receiving bar is provided on one side of the top of the machine platform between the baffle plate and the supporting plate, and the receiving bar faces the electric heating plate.

[0011] The utility model has the following advantages: according to the width of the opening of the packaging bag to be sealed, the knob can be manually loosened first, so that the two limit blocks between the slide groove and the guide groove can be moved, and when the distance between the two limit blocks is the same as the width of the opening of the packaging bag, the knob can be tightened again to fix the limit blocks, so that when the opening of the packaging bag is sealed, the opening end of the packaging bag can be attached to the space between the two limit blocks and extended between the electric heating plate and the receiving strip, so that the problem of the sealing opening being tilted due to the tilt of the packaging bag can be effectively avoided;
