Description
Technical Field
[0001] The utility model relates to the technical field of vacuum sealing machines, in particular to a vacuum sealing machine with a smooth cutting knife. Background Art
[0002] A vacuum sealing machine is a device used to seal foods, medicines, and other items. Its working principle is to create a low-oxygen environment by pumping out the air in the packaging bag, which helps to extend the shelf life of the items, prevent oxidation, and inhibit bacterial growth. Vacuum sealing machines are often used in households, restaurants, and the food processing industry to maintain the freshness of foods and extend their shelf life.
[0003] When the cutting knife of the existing vacuum sealing machine is in use, it is prone to jamming. At the jammed position of the cutting knife, the sealing bag may not be cut off. The user needs to push the cutting knife back and forth, which is likely to leave inconsistent cut marks on the sealing bag, affecting the flatness of the cut of the sealing bag, making it easy for the size of the cut sealing bag not to meet the preset value, resulting in waste of the sealing bag. Moreover, during the process of pushing the cutting knife back and forth, it is possible to scratch the user's fingers. In addition, the sealing bag may leak air during subsequent use, affecting the preservation effect of the food. Also, the position where the cutting knife is installed is difficult to disassemble, which is not conducive to the replacement of the cutting knife. Summary of the Utility Model
[0004] The utility model provides a vacuum sealing machine with a smooth cutting knife, which can effectively solve the above problems.
[0005] The utility model is implemented as follows:
