Description

Technical Field

[0001] The utility model relates to the technical field of packaging bag sealing, in particular to a packaging bag sealing device for food packaging. Background Technique

[0002] With the rapid development of the food industry, food packaging plays an increasingly important role in ensuring food safety, extending the shelf life, and enhancing the product appearance. During the food packaging process, as one of the key devices, the performance of the sealing device directly affects the sealing effect of the packaging and the production efficiency. Although the existing packaging bag sealing devices for food packaging can meet the basic needs in daily life, there are still many deficiencies in their application on the production line, especially the problems of low sealing efficiency and poor applicability caused by the static heat sealing method. These problems not only affect the production efficiency but also may pose a potential threat to food safety.

[0003] The existing packaging bag sealing devices for food packaging usually adopt the static heat sealing method, that is, the sealing part of the packaging bag is heated by a fixed heating plate to make it melt and bond together. Although this sealing method is easy to operate, its sealing efficiency is relatively low in the application on the production line. During the static heat sealing process, it is necessary to keep the sealing part of the packaging bag in contact with the heating plate for a period of time to ensure sufficient melting. However, this process takes a long time. Especially in a high-speed production line, this inefficient sealing method becomes a bottleneck restricting the production efficiency. In addition, during the static heat sealing process, it is difficult to accurately control the temperature and pressure of the heating plate, which easily leads to uneven sealing, affecting the sealing effect, and even may cause air leakage or seepage, affecting the freshness and safety of food.

[0004] The existing packaging bag sealing devices for food packaging have obvious deficiencies in terms of applicability. There are significant differences in the material, thickness, and size of different types of food packaging bags, while the existing sealing devices often can only adapt to specific types of packaging bags, lacking versatility and flexibility. For example, for thin plastic bags, the static heat sealing method may cause the sealing part to overheat and burn, affecting the appearance and safety; while for thick composite bags, static heat sealing may not provide enough heat, resulting in an insecure seal. In addition, for some special packaging bags, such as those with zippers or easy-open lids, the existing sealing devices often cannot handle them effectively, requiring additional equipment or manual operations, increasing the production cost and complexity.

[0005] The existing sealing device for food packaging bags also needs to be improved in terms of automation. In modern food production lines, automation and intelligence are the keys to improving production efficiency. However, the existing sealing devices usually require manual intervention, such as manually placing the packaging bags and adjusting the sealing position, which not only increases the labor cost but also may lead to unstable sealing quality due to human factors. Especially in the production mode of multiple varieties and small batches, it is difficult for the existing sealing devices to quickly switch and adapt to different types of packaging bags, affecting the flexibility and efficiency of production.

[0006] From the perspective of user experience, the existing sealing devices for food packaging bags also have deficiencies in terms of operation convenience and safety. For small enterprises and individual merchants, the existing sealing devices are often large in size and complex in operation, and are not suitable for use in limited spaces. In addition, since high-temperature heating is required during the sealing process, users are easily scalded during operation, posing certain safety hazards. Especially in the home use scenario, operation simplicity and safety are the most concerned issues for users, and the existing sealing devices obviously cannot meet the requirements in this regard.

[0007] Therefore, how to provide a sealing device for food packaging bags is an urgent problem that needs to be solved by those skilled in the art. Utility Model Content
