Lifting external vacuum packaging machine is vacuum or nitrogen-filled sealing packaging for electronic components, hardware, meat, dry goods, cloth wool products, whole grains, vegetables and fruits, pharmaceuticals, plastic raw materials, food, chemical raw materials, etc. It can achieve anti-oxidation, anti-corrosion, anti-mildew, moisture-proof and other fresh-keeping and quality-preserving effects. Lifting external vacuum packaging machine adopts no vacuum chamber, and the air nozzle directly vacuums or fills the packaging bag with nitrogen. The size of the packaging is limited, and it occupies a small space.This machine adopts long air nozzle design, and the air nozzle length can be adjusted freely from 0--200MM. In addition to the automatic lift transmission design, just press the lift switch. Automatically raise or lower to the appropriate vacuum position, so that the pumping and inflation speed is fast, the work efficiency is high, and the operation is simple and convenient.

This machine adopts no vacuum chamber, and the air nozzle directly evacuates or fills the packaging bag with nitrogen. The size of the packaging is not limited, occupies a small space, and can be used wherever it is moved. The photoelectric positioning conveying table is matched, and the barrels or boxes are transported from the conveying table to the bottom of the machine head. The photoelectric positioner automatically detects the barrels or boxes and other items, and automatically stops the conveying. Then the machine head automatically descends, and the procedures such as bagging, vacuuming, and sealing are completed. , the machine head is automatically raised to the original position and other processes are automatically completed. As long as the items are continuously transported and packaged, the equipment will continue to circulate continuously, thereby improving work efficiency, saving labor costs, and truly realizing automated equipment.
