The vertical packaging machine is a machine that makes a roll of flexible packaging material into a bag tube, fills it with the material, and seals it. The three functions are automatically and continuously completed. In conjunction with the metering and filling machinery on the upper road, the vertical packaging machine is often used to pack block, flake, granular, stalk, powder, and fluid and semi-fluid materials.
At present, the empty machine running of the vertical packaging machine on the market can basically reach 120bpm (bags/min), and the speed can reach 60-80bpm with the upper measuring and filling machine.
The characteristic of the vertical packaging machine is that the supply cylinder of the packaged material is set inside the bag maker, and the bag making and filling of the material are carried out in a vertical direction from top to bottom. The vertical packaging machine is mainly composed of a metering device, a transmission system, a horizontal and vertical sealing device, a former, a filling tube, and a film pulling and feeding mechanism.
Its working principle is: the roll film placed on the supporting device is wound through the guide roller group and the tension device. After the photoelectric detection control device detects the position of the trademark pattern on the packaging material, it is rolled into a film cylinder by the former. Wrapped on the surface of the filling tube. First, a longitudinal heat sealer is used to longitudinally heat seal the film at the interface that is rolled into a cylinder to obtain a sealed tube, and then the cylindrical film is moved to the transverse heat sealer for horizontal sealing to form a packaging bag tube. The metering device fills the measured items into the packaging bag through the upper filling tube, and then is heat-sealed by the transverse heat sealer and cut in the center to form the packaging bag unit body and at the same time form the bottom seal of the next tube bag
