Description

【Technical field】 [0001] The invention relates to the technical field of packaging machinery, in particular to a fruit vacuum packaging machine. 【Background technique】 [0002] Fruit packaging is an indispensable part of fruit sales. In terms of fruit, vacuum packaging is often used for the packaging of some nuts and preserved fruit products such as hazelnuts, chestnuts, and cashews, as well as the packaging of medicinal materials such as Luo Han Guo. [0003] Most of the fruit packaging on the market adopts the packaging method of box type and mesh plastic film. When the person who buys fruit checks the damage of the fruit, he often needs to open the box and remove the mesh plastic film to check. The process is very troublesome. [0004] Vacuum packaging using transparent film can solve the problem of inconvenient fruit inspection, but most of the vacuum packaging machines on the market use the packaging method of heat sealing and vacuuming after bag making. Finally, they ...

AI Technical Summary

Problems solved by technology

[0004] Vacuum packaging using transparent film can solve the problem of inconvenient fruit inspection, but most of the vacuum packaging machines on the market adopt the packaging method of heat sealing and vacuuming after bag making. After that, they are piled up in the packaging bag to form a pile. When one of the fruits deteriorates, the material components produced by the deterioration will easily affect other fruits, causing one bag to be damaged if one is damaged, causing a lot of waste.

At the same time, for the packaging of some preserved fruits, in order to facilitate portability and place additives in the film, the two sides of the package will need different packaging materials with large differences in properties.

[0005] In the method of laminating two films in the prior art, it is difficult for the suction port of the vacuum machine to pass into the inner cavity formed by the two packaging films
