Description

Technical Field

[0001] The utility model belongs to the technical field of vacuum sealing machine products, in particular to a character vacuum sealing machine. Background Art

[0002] At present, the vacuum sealing machine uses a vacuum device to vacuum the vacuum packaging bag, and then heat-seals the bag opening of the vacuum packaging bag through a heat sealing process. The vacuum sealing machine can store food in the vacuum packaging bag after vacuuming, and can maintain the vacuum degree for a long time to achieve the preservation performance of the food.

[0003] In the prior art, vacuum fresh-keeping machines generally need to print the production date and batch number function, otherwise the user cannot accurately know the production date and batch number of the food in the fresh-keeping bag, cannot clearly know whether the product is expired, and cannot trace the product accordingly.

[0004] To this end, some people have also developed a printing wheel structure to print on fresh-keeping bags, but the printing process of the printing wheel requires a printing wheel with protruding numbers. The production cost of the printing wheel is high, and it is easy to be damaged after long-term use. The cost of replacing or repairing it after damage is high. At the same time, the method of using the printing wheel has a complex structure and requires a larger three-dimensional space for installation and placement, which increases the overall size of the machine, which is inconsistent with the current design concept of lightweight and miniaturized small household appliances, and cannot better meet the user's needs for convenience of use and miniaturized structure.

[0005] Therefore, it is urgent to develop a multifunctional vacuum sealing machine with characters that is simple in structure, easy to use, lightweight and miniaturized, and has a large sealing area and can print characters. Utility Model Content
