Description

Technical Field

[0001] This utility model relates to the field of food packaging technology, specifically to a sealing device for food packaging bags. Background Technology

[0002] With the rapid development of the food industry, food packaging plays an increasingly important role in ensuring food safety, extending shelf life, and improving product appearance. In the food packaging process, vacuum sealing devices are one of the key pieces of equipment, and their performance directly affects the sealing effect and production efficiency of the packaging.

[0003] A search revealed that patent application number 202422301556.6 discloses a food packaging bag sealing device, including a sealing box, a sealing groove, a power component, and a heat sealing component. The sealing groove is located on the sealing box, the power component is fixedly installed inside the sealing box, and the heat sealing component is mounted on both the sealing box and the power component. This invention can be used in daily life or in conjunction with a production line. The food packaging enters through the larger opening of the sealing groove. The power motor drives the transmission shaft, transmission wheel, auxiliary shaft, pulley, and belt to rotate the heat sealing wheel and heat insulation ring. A high-frequency generator is activated, and the heating coil heats the heat sealing wheel. The food packaging enters through the opening of the sealing groove, passing between the upper and lower heat sealing wheels. The convex shape of the heated heat sealing wheel heat seals the food packaging. Simultaneously, the rotation of the heat sealing wheel ensures better sealing of the food packaging during transportation, making it better suited for heat sealing of food packaging openings on production lines.

[0004] In the use of existing strip sealing machines, food packaging bags need to be placed inside and heat-sealed. However, during this process, the gap between the upper and lower cover seats cannot be enlarged, otherwise it will affect the heat sealing effect of the entire bag opening. Secondly, when placing the bag, the entire bag opening needs to be placed between the upper and lower cover seats, and the left and right positions cannot exceed the heat sealing position, otherwise the heat sealing effect will be poor and the overall practicality will be low.

[0005] Therefore, we propose a sealing device for food packaging bags. Utility Model Content
