The external pumping vacuum packaging machine is a device that puts the packaging on the outside of the vacuum chamber to complete vacuum packaging. The external pumping vacuum packaging machine is mainly designed for the vacuum packaging of larger packages, which is slightly different from the internal pumping structure. The external pumping vacuum machine is mainly put into the bag of the package to be evacuated through the suction nozzle, evacuate the air inside, and then exit the suction nozzle, so as to complete the sealing operation.
Compared with the internal pumping vacuum packaging machine, the external pumping vacuum packaging machine is more suitable for the vacuum packaging of large items.
Because the articles to be evacuated are placed outside the vacuum packaging machine, there are only requirements for the sealing size of the sealing materials, but the requirements for the size of the packaging materials are basically not strict.
Pneumatic sealing is adopted, which is clean, environment-friendly and reliable; Because the whole machine adopts PLC circuit programmable control, the performance is stable; Sponge like silicone strip can ensure good sealing in the bag after air extraction; The double chamber vacuum packaging machine adopts variable stroke cylinder to make the seal neat and flat; Stainless steel worktable, according to the size of the packaging object, the height can be adjusted arbitrarily; Equipped with casters, it is easy to move and can move the workplace at will; The external vacuum pumping machine can select manual or foot switch for convenient operation.
