Solutions for Vertical Packaging Machines
The vertical packaging machine is a machine that makes a roll-shaped flexible packaging material into a bag tube, fills the material, and seals it, and the three functions are automatically and continuously completed. In conjunction with the previous metering and filling machine, the vertical packaging machine is often used for packaging block, flake, granular, stalk, powder, and fluid and semi-fluid materials.
At present, the empty machine of the vertical packaging machine on the market can basically reach 120bpm (bags/min), and the speed can reach 60-80bpm with the previous metering and filling machine.
Process Description:
The vertical packaging machine is characterized in that the feeding cylinder of the packaged material is set on the inside of the bag maker, and the bag making and filling material are carried out from top to bottom along the vertical direction. The vertical packaging machine is mainly composed of measuring device, transmission system, horizontal and vertical sealing device, former, filling tube and film pulling and feeding mechanism.
The working principle of the vertical packaging machine is as follows: the roll film placed on the supporting device is wound around the guide roller group and the tensioning device. The cylinder wraps around the surface of the filling tube. First, the longitudinal heat sealer is used to longitudinally heat seal the film at the interface part rolled into a cylinder to obtain a sealed tube, and then the cylindrical film is moved to the transverse heat sealer for transverse 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 heat-seals it by a transverse heat sealer and cuts it in the middle to form a packaging bag unit body, and at the same time form the bottom seal of the next tube bag.
