Vacuum packaging device

A vacuum packaging device, including:

• a shell having a hollow area for garbage bags to vertically pass through;
• a fixture, located on the shell, which can partially close and clamp the garbage bags through the closing action of a clamping portion, and a poking portion on an inner side of the clamping portion pokes out an air hole in a locale after clamping;
• a vacuum pumping mechanism, which is located on the shell and can vacuum the garbage bags through the air hole, and
• a heating element, which is located in the fixture and used to locally fuse and maintain vacuum sealing after the garbage bags are vacuumized;
• wherein the fixture comprises a driving mechanism and a clamping portion, the clamping portion comprises a swing arm and a fixed arm that are disposed on the shell, the swing arm can swing be ween positions where the swing arm maintains horizontal contact with and disengaged from the fixed arm, and the driving mechanism is used to drive the swing arm to swing;
• wherein the driving mechanism comprises a rotating motor and a pulling rope one end of the pulling rope is connected to the swing arm, and the other end of the pulling rope is connected to a rotating end of the rotating motor, and the polling rope can drive the swing arm to swing while the rotating end rotates;
• wherein the rotating motor is fixed on one side of the fixed arm, and the rotating end of the rotating motor is fixed with a wire wheel connected to the pulling rope, and the rotating end in rotation makes the pulling rope wrap around or release the wrapping around the wire wheel, an outer position in the corresponding hollow area of the shell is provided with a transmission wheel that can move between a free end and an away position of the fixed arm, and the transmission wheel maintains local contact with the pulling rope to forces the pulling rope to bend outside the hollow area, and the pulling rope drives the transmission wheel to approach the fixed arm while driving the swing arm to approach the fixed arm, and a first tension spring and a second tension spring are further provided, the first tension spring is used to apply a pulling force to make the transmission wheel move away from the fixed arm, and the second tension spring is used to apply a pulling force to make the swing arm swing away from the fixed arm.
