Description

Manual multifunctional vacuum plastic packaging machine Technical Field The utility model relates to the technical field of packaging equipment and vacuum, in particular to an improvement of a manual packaging bag vacuum plastic sealing machine. Background Traditional food storage modes are easy to be affected with damp, oxidized or deteriorated, and the quality guarantee period of the food can be effectively prolonged by the vacuum packaging technology. The common vacuum sealing equipment in the market at present mainly comprises a household handheld vacuum sealing machine, wherein the household handheld vacuum sealing machine is small in size and suitable for daily household use, but has a limited vacuumizing effect. The industrial vacuum packaging machine is suitable for large-scale production, has stronger vacuumizing capability, and has higher equipment cost. The full-automatic vacuum sealing machine is integrated with an intelligent control system, and has high automation degree. These devices have certain drawbacks for everyday household use. Disclosure of utility model The utility model aims to overcome the defects and shortcomings of the prior art, and provides a manual multifunctional vacuum plastic packaging machine which is simple in structure, good in compactness, simple to operate, stable in sealing effect, low in cost, strong in vacuumizing capability and good in vacuum property, and meanwhile, can be compatible with a plurality of bag bodies made of different materials.
