[0033] By setting the uniform heating component 5, the electric heating wire 9 generates temperature to heat the glycerin inside the lower heat-sealing tube 2 and the upper heat-sealing tube 4. The glycerin can be heated to a higher temperature to seal the sealed bag. At the same time, the motor 52 is driven to rotate, so that it drives the reciprocating screw rod 53 at the output end to rotate. The moving plate 54 threadedly connected on its surface moves inside the lower heat-sealing tube 2 and the upper heat-sealing tube 4 to mix and stir the heated glycerin to make the overall temperature uniform. The heat is transferred through the lower heat-sealing tube 2 and the upper heat-sealing tube 4 to heat-seal the placed sealed bag, thereby avoiding the uneven heating and incomplete sealing caused by the quality problems of the single electric heating plate when heating and heat sealing, which affects the sealing effect of the sealed bag.

[0037] In the utility model, the working steps of the device are as follows:

[0038] First, the electric heating wire 9 generates temperature to heat the glycerin inside the lower heat-sealing tube 2 and the upper heat-sealing tube 4. The glycerin can be heated to a higher temperature to seal the sealed bag. Then, the driving motor 52 rotates, so that it drives the reciprocating screw rod 53 at the output end to rotate, and the movable plate 54 threadedly connected on its surface moves inside the lower heat-sealing tube 2 and the upper heat-sealing tube 4 to mix and stir the heated glycerin to make the overall temperature uniform. The heat is transferred through the lower heat-sealing tube 2 and the upper heat-sealing tube 4 to heat-seal the placed sealed bag. Finally, according to the size of the sealed bag, the two sliders 62 are moved to drive the guide grooves 63 fixed on the top surface to move. When the spacing between the two guide grooves 63 matches the size of the sealed bag, the sealed bag can be inserted between the lower heat-sealing tube 2 and the upper heat-sealing tube 4 through the guide grooves 63 on both sides to heat-seal the sealed bag.
