[0002] Food packaging is an integral part of food commodities. It is one of the main processes in the food industry. It protects food and prevents it from being damaged by biological, chemical, and physical external factors during the circulation process from leaving the factory to the hands of consumers. It can also have the function of maintaining the stable quality of the food itself. It is convenient for food consumption and first shows the appearance of food and attracts consumers. It has value beyond material cost.

[0003] Usually, a corresponding device needs to be set up in a food production line to seal the mouth of a food bag. There is an automatic food bag sealing device with a Chinese patent announcement number of CN211969918U. The cooperation of a lower buckle frame and an upper buckle frame facilitates the placement of food bags and the fixing of food bags. The lower buckle frame can be limited by the setting of an elastic partition, and the lower buckle frame can be tilted or offset, so that the food bag can be offset during sealing, thereby avoiding the influence of the offset on the sealing. The sealing part can be pressed tightly by the setting of a pressing plate, and wrinkles can be prevented at the sealing part, thereby affecting the sealing effect of the sealing part.

[0004] However, since the device is limited to sealing at a fixed position, it is difficult to meet different sealing requirements and has poor practicality. Utility Model Content
