Vacuum sealer and bag-cutting type sealing method

Abstract

The invention discloses a vacuum sealer and a bag-cutting type sealing method. In the vacuum sealer, at least one cutter device is slidably installed at an upper cover; a heat sealing strip and a vacuumizing groove are arranged at the front side of the upper part of the upper cover; the upper cover or a lower cover is provided with a bag body storage chamber; a dismountable automatic rewinding shaft is rotationally installed in the bag body storage chamber; an elastic rewinding mechanism used for driving the automatic rewinding shaft to rewind and an elastic one-way locking mechanism used for locking the automatic rewinding shaft are installed at the end part of the automatic rewinding shaft; the cutter device protrudes from the bottom surface of the lower cover; and after the upper cover is locked on the lower cover in a covering way, a cutter moves back and forth at one side of the heat sealing strip or one side of the vacuumizing groove and is used for cutting a bag body which is pressed tightly between the upper cover and the lower cover. The vacuum sealer disclosed by the invention is simple in structure; the bag is cut at the original heat sealing strip or vacuumizing groove of the lower cover, so more convenient bag cutting is realized; after being cut off, the bag body can be automatically rewound by a vacuum packaging bag roll after the cover is opened, so the operation steps of a user are reduced, and the vacuum sealer is simpler, more convenient and quicker to operate.

Description

technical field [0001] The invention relates to the technical field of household vacuum sealing machines, in particular to a vacuum sealing machine and a bag cutting and sealing method of the vacuum sealing machine. Background technique [0002] The household vacuum sealing machine is equipped with an upper cover and a lower cover, and a vacuum groove is arranged on the lower cover. When vacuuming, insert the mouth of a bag such as a vacuum packaging bag into the vacuum groove. The bag such as the vacuum packaging bag is vacuumized, and finally the bag opening is heat-sealed through the heat-sealing strip of the lower cover to complete the sealing action. [0003] For the use of roll-packed vacuum packaging bags for vacuum packaging, in order to facilitate users to cut the bags, the vacuum sealing machine is generally equipped with a knife box and a sliding cutter on the top surface of the upper cover. The Chinese patent number is "201020127855.8", the patent name As shown ...

AI Technical Summary

Problems solved by technology

Both the upper cover and the lower cover must be equipped with heat-sealing strips, the structure is complex and the cost is high

[0004] And it is inconvenient to use. It needs to be moved to the knife box on the top surface of the upper cover first, and the front end of the bag body of the vacuum packaging bag is passed through or pressed against the knife box on the top surface of the upper cover, and then Cut the bag body by sliding the cutter, and then transfer the cut bag body to the vacuum tank, heat seal one end first to form a bag that can be filled with food, after filling the food, put the other One end is inserted into the vacuum tank for vacuuming and heat sealing, which is troublesome to use

[0005] For a vacuum packaging machine with a roll-shaped vacuum packaging bag built into the internal storage chamber, it is more troublesome to use. When cutting the bag body, it is necessary to first pull out the bag placed in the storage chamber in the vacuum sealing machine for a longer period of time. length, the length of the pulled bag must be much longer than the length of the cut bag, so that the bag can be pulled to the cutter and cut off, and then the remaining bag must be manually rolled back to shrink it back to the bag storage chamber In the process, one end of the bag body is transferred to the vacuum tank, and one end is heat-sealed first, which is more inconvenient to use, so it is necessary to improve
