The vertical explosion-proof vacuum packaging machine is specialized equipment designed for packaging flammable and explosive materials. Based on standard vacuum packaging machines, it incorporates explosion-proof modifications, making it suitable for specialized industries such as chemical engineering, pharmaceuticals, and military manufacturing. Below is a detailed overview:
Unlike conventional chamber-type vacuum packaging machines, this vertical model utilizes the packaging bag itself as a sealed chamber. The operating process involves the following steps: load the product into a composite plastic vacuum bag → fit the bag's opening over the machine's air suction nozzle → start the machine → the upper pressure plate descends to seal the bag opening → the vacuum pump automatically activates to extract air to a preset vacuum level → apply pressure and heat to hermetically seal the bag opening.
- All control electrical components are installed in an explosion-proof cabinet.
- Pushbuttons and switches adopt explosion-proof configurations.
- The vacuum pump motor, solenoid valves, and heating elements for sealing are explosion-proof rated.
- Electrical wiring is routed through explosion-proof conduits.
- The entire unit is certified with explosion-proof certification.
- Vertical design minimizes floor space, facilitating operation and maintenance.
- Suitable for large-bag packaging applications.
- The height of the sealing head is adjustable to accommodate different bag sizes.
- Equipped with multiple air suction nozzles (typically 2 nozzles operating simultaneously) to enhance air extraction speed and efficiency.
- Features double-sided heating sealing technology, ensuring reliable sealing even if the bag opening is contaminated with powder (no leakage).
