Description

Technical Field

[0001] The utility model belongs to the technical field of plastic packaging bag production, in particular to an edge sealing device for plastic packaging bag production. Background Art

[0002] The edge sealing device in the production of plastic packaging bags is usually a heat sealing device, which uses a heat sealing strip or a hot knife to heat and press the edge of the plastic film to form a sealed edge. This device can ensure that the edge of the packaging bag is firmly sealed to prevent product leakage or moisture. At the same time, the heat sealing device can also perform edge sealing of different shapes and sizes as needed to meet different packaging needs.

[0003] The edge sealing device in the production of plastic packaging bags heats and presses the edges of the plastic packaging bags to form a firm edge seal, which can effectively protect the products inside the packaging bags from external pollution or moisture intrusion. The edge sealing device can ensure that the opening of the plastic packaging bag has good sealing to prevent product leakage or foreign substances from entering. Through the edge sealing device, the edges of the plastic packaging bags can be made neat and flat, improving the appearance and texture of the packaging bags, thereby increasing the attractiveness of the products. The working principle of the edge sealing device of plastic packaging bags is usually to use heat sealing technology. First, the edge sealing device will heat the edge of the plastic packaging bag through a heating element (such as a heat sealing strip or a hot knife) to make it reach a certain temperature, usually higher than the melting point of the plastic, so that the plastic softens and has a certain viscosity. Once the edge of the plastic is heated and softened, the edge sealing device will apply a certain pressure, usually through a roller or a pressing device , the edges of the plastic packaging bag are tightly pressed together. After the pressing is completed, the edge sealing device will stop heating and wait for a certain period of time to allow the plastic edge to cool and solidify to form a firm edge seal. Through these steps, the edge sealing device of the plastic packaging bag can ensure that the edge of the plastic bag is firmly sealed, thereby achieving the purpose of protecting the product and improving the sealing and aesthetic effects. The problem with the above technology is that in the process of edge sealing the plastic packaging bag by the edge sealing device, it is necessary to assist in pushing the material through the conveyor table, but the conveyor table itself does not have a component that can assist in limiting the position of the plastic packaging bag. Therefore, the plastic packaging bag is easily affected by external forces and deviates. When the plastic packaging bag is deviated, it is easy to cause the edge sealing device to be mis-pressed. Therefore, it is not convenient for users to quickly press and seal the plastic packaging bag through the edge sealing device. Utility Model Content
