Document Type and Number:
WIPO Patent Application WO/2020/156146
Kind Code:
A1
Abstract:
A vacuum sealing machine capable of locking a cover automatically having an upper cover limiting mechanism, comprising: an upper cover (10), a lower base (20), and vacuumizing grooves. The upper cover (10) is hinged to the lower base (20), and the vacuumizing grooves are located at the front portion of the vacuum sealing machine. The vacuum sealing machine comprises a cover locking mechanism and an upper cover limiting mechanism. The cover locking mechanism is mounted on the upper cover (10) or the lower base (20); the cover locking mechanism is connected to the upper cover limiting mechanism; the upper cover limiting mechanism comprises a limiting lock plate (40) and a limiting portion (36); the limiting lock plate (40) movably mounted on the upper cover (10) is snap-fitted with the limiting portion (36) provided on the lower base (20), or the limiting lock plate (40) movably mounted on the lower base (20) is snap-fitted with the limiting portion (36) provided on the upper cover (10); and the limiting lock plate (40) and the limiting portion part (36) are snap-fitted to form a bag-entry gap having a set height between the limiting lock plate (40) and the limiting portion (36). The present vacuum sealing machine can automatically lock and open the cover, so that the entire vacuum sealing work can be automatically completed only by fixing a vacuum packaging bag with both hands and pressing a start button of the vacuum sealing machine. The use of the machine is simple and convenient.
