[0002] A continuous film bag sealing machine is a plastic packaging bag heat sealing device widely used in the packaging industry, specifically for continuously sealing film bags. The continuous film bag sealing machine converts electrical energy into heat energy through a heating element, causing the film material at the sealing part to melt by heating, and then fusing together under the action of pressure to achieve sealing.

[0003] For the existing small continuous film bag sealing machine, the operation method of manually pinching the packaging bag and putting it into the heat sealing conveyor belt may affect the heat sealing efficiency of the packaging bag to a certain extent. The main reasons are as follows: First, the operation speeds are inconsistent. The operation speeds of different workers may vary. Some workers are quick, while some may be slow, which will lead to an unstable rhythm of the packaging bag entering the heat sealing conveyor belt, thus affecting the overall heat sealing efficiency; Second, the placement accuracy. When manually placing the packaging bag, there may be inaccurate positions. Sometimes, it needs to be readjusted and placed again, reducing the efficiency; Third, manual fatigue: Long-term repetitive operations are likely to make workers feel fatigued, and the operation speed and accuracy may decrease, thereby affecting the heat sealing efficiency. Therefore, it is necessary to design an efficient plastic packaging bag heat sealing device to solve the above problems. Content of the Utility Model
