The single-chamber vacuum packaging machine consists of a plexiglass cover, a vacuum chamber, a body electrical control system, a vacuum system, etc. The lower working chamber is provided with a hot-press sealing device, and the heating element is a nickel-chromium band, which is mounted on the bakelite hot pressed body. Absolutely insulated from the vacuum chamber, the bakelite hot press frame is closely attached to the airbag, and the airbag is in a vacuum state before heat sealing. When the heat seal is performed, the airbag passes through the electromagnetic valve to generate a pressure difference, thereby making the airbag larger, and the heating head ( The nickel-chromium belt is lifted up, the pocket is pressed tightly, and heated at the same time to complete the sealing.
The single-chamber vacuum packaging machine consists of a vacuum valve consisting of an exhaust valve, an inflation valve, a bleed valve, etc. as an actuator. When the vacuum pump is started, the vacuum chamber can be evacuated. When the predetermined vacuum setting is reached, the vacuum pump stops, and the entire procedure is completed. Go to the next heat seal procedure.
