[0002] A heat sealing bag sealing device is a device used to seal packaging bags. It usually uses heating to melt the plastic material at the opening of the packaging bag and bond them together, thereby achieving the purpose of sealing. The heat sealing bag sealing device has the characteristics of simple operation, fast sealing speed, and good sealing effect. It is widely used in packaging production lines in food, medicine, chemical and other industries. It can seal packaging bags of various materials, such as plastic bags, aluminum-plastic composite bags, etc. Different types of heat sealing bag sealing devices may differ in heating methods, sealing widths, applicable bag types, etc. Users can choose appropriate equipment according to actual needs. The emergence of heat sealing bag sealing devices has improved the efficiency and quality of packaging production, and provided reliable guarantees for product storage, transportation and sales.

[0003] The prior art includes a utility model with publication number CN220096841U, which discloses a heat-sealing bag device.

When the buckles 822 move to the maximum spacing, the connecting frame 817 can be pulled outward, thereby removing the cleaning box 818 from the buckle frame 816 to carry out the impurity cleaning operation. By providing the auxiliary component 8, the equipment can clean the heating surface during processing, thereby reducing the problem of impurities adhering to the surface of the heat-sealed structure, affecting the sealing effect of the subsequent packaging bags, and further improving the processing effect of the bag sealing device.
