Vertical packaging machine overall solution
Process introduction
The vertical packaging machine is a machine that makes a roll-shaped flexible packaging material into a bag, fills the material, and seals it, and the three functions are automatically and continuously completed. In conjunction with the above-mentioned metering and filling machinery, vertical packaging machines are often used for packaging blocks, sheets, granules, stems, powders, and fluid and semi-fluid materials. At present, the vertical packaging machine on the market can basically run at 120bpm (bags/min), and the speed can reach 60-80bpm with the on-line metering and filling machine.
Process Description
The vertical packaging machine is characterized in that the feeding cylinder of the packaged material is arranged inside the bag maker, and the bag making and filling materials are carried out in the vertical direction from top to bottom. The vertical packaging machine is mainly composed of a measuring device, a transmission system, a horizontal sealing and vertical sealing device, a molding device, a filling tube and a film pulling and feeding mechanism.
The working principle is as follows: a film of a roll placed on a supporting device, a group of guiding rods and a tensioning device, and a position of a trademark pattern on a packaging material is detected by a photoelectric detecting and controlling device, and then rolled into a film cylinder by a molding machine. Wrap on the surface of the filling tube. First, the film of the interface portion rolled into a cylinder is longitudinally heat-sealed by a longitudinal heat sealer to obtain a sealed tube, and then the tubular film is moved to a transverse heat sealer for transverse sealing to form a package bag. The metering device fills the metered item into the package through the upper filling tube, and then heat seals by the transverse heat sealer and cuts it in the center to form the package unit body, and at the same time forms the bottom seal of the next package.
