The invention discloses a negative pressure buckling device and a vacuumizing plastic packaging machine. The negative pressure buckling device comprises a base, a floating base and a telescopic bag. The base is installed on a lower shell assembly of the vacuumizing plastic packaging machine and provided with a plurality of sliding parts. The floating base is provided with matching parts matched with the plurality of sliding parts. By matching the sliding parts with the matching parts, the floating base can reciprocate linearly on the basis of the base under the action of external force. The telescopic bag is circular, the upper end of the telescopic bag is connected with the base, and the lower end of the telescopic bag is connected with the floating base, so that a first cavity is formedamong the telescopic bag, the base and the floating base. The first cavity is variable in size on the basis of deformation of the telescopic bag. The base is further provided with a suction part communicating with the first cavity. The suction part is used for being connected with a preset suction device, so that an air pressure value in the first cavity is lower than an atmospheric pressure value, and the floating base linearly moves on the basis of the base to get close to the base under the action of the internal and external pressure difference of the first cavity.
Description
technical field [0001] The invention relates to plastic sealing equipment, in particular to a negative pressure fastening device and a vacuum-pumping plastic sealing machine. Background technique [0002] The vacuum-pumping plastic sealing machine generally includes an upper shell assembly and a lower shell assembly that are fastened to each other. A closed space is formed between the upper shell assembly and the lower shell assembly, and the packaging bag to be vacuumed is clamped between the upper and lower shells, and Make the mouth of the packaging bag in the closed space, connect the closed space to a vacuum device and pump the air in the closed space to complete the vacuuming process for the packaging bag. [0003] The upper and lower shells of the existing vacuum-pumping plastic sealing machine are snapped together by the locks on the left and right sides, and the operator presses the upper shell assembly with both hands to make it fit the lower shell assembly. The e...
