Vacuum package machine

A vacuum package machine, comprising:

• a lower housing (1);
• an upper turning cover (2), rotationally disposed on the lower housing (1), wherein the lower housing (1) is internally provided with a vacuum cavity (9) configured to store water discharged from a package bag during vacuum pumping, and the vacuum cavity (9) is internally provided with a water level probe (19);
• and
• a clamping component (3), disposed between the lower housing (1) and the upper turning cover (2) and configured to tightly clamp a bag opening of the package bag and cooperate with the vacuum cavity (9) to form a sealed cavity for vacuum pumping;
• wherein the clamping component (3) comprises a bag opening clamping plate (32), the bag opening clamping plate (32) is rotationally disposed in the vacuum cavity (9), and is configured to cooperate with an inner wall of the vacuum cavity (9) to tightly clamp the bag opening of the package bag;
• a hot-melting sealing component (11) is disposed on the upper turning cover (2), and is configured to melt the bag opening of the package bag and bond the bag opening position of the package bag to realize sealing;
• and
• a device installing plate (4) is disposed in the upper turning cover (2), a cooling component (16) for cooling the hot-melting sealing component (11) and a vacuum pump (18) are disposed on the device installing plate (4), an air pumping end of the vacuum pump (18) communicates with the vacuum cavity (9) through a first pipeline, and a breathable acoustic material (23) is disposed inside the vacuum pump (18) and is configured to absorb noise during air exhausting.
