[0006] Preferably, guide rod support plates and screw rod support plates are fixed on both sides of the heat sealing machine. A flat guide rod is fixed on one side of the guide rod support plate, and a flat screw rod is rotatably connected to one side of the screw rod support plate. The flat screw rod is driven to rotate by a third motor, which is fixed to one side of the heat sealing machine. A flat plate is threaded onto the surface of the flat screw rod, and the flat plate is slidably connected to the flat guide rod. In existing technologies, the heat-sealing device used for the inner milky white film of container bags is prone to wrinkling before heat sealing. This problem not only affects the uniformity and sealing of the heat sealing, but may also lead to insufficient seam strength, thus affecting the quality of the final product. The wrinkles are often caused by uneven material tension or inaccurate positioning of the material by the equipment, resulting in the inability to form an ideal contact surface during the heat sealing process, thereby increasing the instability and uncertainty of production. To address this problem, this utility model adopts a pressing structure. After the material is prepared, the third motor is started. Driven by the third motor, the flat plate descends to contact the material surface. At this time, the first motor is started to flatten the material as it is delivered to the area to be heat-sealed.

[0008] Preferably, the bottom of the heat sealing machine has a cavity, and a lifting cylinder is fixed to the inner wall of the cavity. A lifting platform is fixed to the drive end of the lifting cylinder. When the heat sealing device does not need to be moved, the lifting cylinder is activated to lower the platform to the same height as the casters, thereby making the heat sealing device more stable when stationary.
