Technical Field

[0001] The utility model relates to the technical field of sealing machines, and more specifically, the utility model relates to a sealing machine for packing bagged food. Background Art

[0002] A sealing machine is a machine for sealing containers filled with products. After the products are loaded into the packaging containers, in order to seal and preserve the products, maintain the product quality, and avoid product loss, it is necessary to seal the containers, and this operation is completed by a sealing machine. There are many materials for making packaging containers, such as paper, plastic, glass, ceramic, metal, composite materials, etc., and the shapes and physical properties of the packaging containers are also different.

[0003] During the process of packing bagged food, operators often use corresponding sealing machines to seal the bagged food. However, in the actual use of the existing sealing machines, although they have the basic sealing function, when generally sealing food packaging bags, due to the irregular shape of the packaging bags, the bag mouths will inevitably tilt. Therefore, operators need to manually place the bag mouths between the two sealing rollers, which not only reduces the efficiency of the sealing operation, but also there are safety hazards in the process of manual placement. Therefore, it needs to be improved. Summary of the Utility Model
