The working principle and main purpose of vertical packaging machine

The working principle and main purpose of vertical packaging machine The vertical packaging machine occupies a small area and is widely used in daily life. It is suitable for packaging all kinds of hardware, powder, granules, tablets and other items. The biggest difference between the vertical packaging machine and other packaging machines is that the supply cylinder of the packaged material is set inside the bag maker, and the bag making and filling 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.       The vertical packaging machine adopts all stainless steel materials, with generous appearance, reasonable structure and more advanced technology. During the packaging process, the material is stretched and fed by the feeding device. The plastic film passes through the film cylinder to form a cylindrical shape, and the side is sealed by the thermal vertical sealing device. At the same time, the package is injected into the bag. The horizontal sealing mechanism is based on the color code photoelectric detection device Cut the package length and position.       The working principle of the vertical packaging machine: the roll film placed on the supporting device is wound around the tensioning device of the guide roller group, and the position of the trademark pattern on the packaging material is detected by the photoelectric detection control device. The film cylinder is 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 a transverse heat sealer and cut in the center to form a packaging bag unit and at the same time form the bottom seal of the next tube bag.
