For vertical packaging, it is suitable for liquids, powders and granules with good fluidity. It relies mainly on its own gravity and can be packaged with certain mechanical effects if necessary. Vertical packaging machines generally have two kinds of packaging. The function, that is, the cutting with the cursor and the cutting of the fixed length, the two cutting functions are convenient to switch, and the packaging method used when the machine is running depends on the packaging film, and the packaging film is roughly divided into a package with a cursor and no cursor, and no cursor. The film is cut with fixed length, and vice versa, with a cursor. For pillow packaging, it is mainly suitable for single-piece or composite packaging with regular shape and sufficient rigidity.
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. 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 lapel former. Wrap 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 cylindrical film is moved to a position of the transverse heat sealer to be transversely sealed to form a package bag. The metering device fills the metered item into the packaging bag through the upper filling tube, and then heat-seales by the transverse heat sealer and cuts in the center to form the package unit body, and at the same time forms the bottom seal of the next tube bag.
The vertical seal shaft (also the film feed shaft) of the vertical packaging machine serves as the system spindle. Horizontal seal, scribing, cutting and other 3 axes follow the spindle operation. The horizontal seal, scribing and cutting servo controller directly grab the film color code signal for position detection. After the film is formed by the former, it becomes a cylinder film and is longitudinally formed. Heat sealing, the packaging film moves downward, the horizontal seal shaft moves, and the material is sent into the cylinder film, and continues to move downward together, and the transverse sealing shaft moves once again when the next cursor signal comes in, so that a pack of three heat seals The action is completed. When the packaging film continues to move downward, the color code sensor detects the color mark, and the driver receives the signal of the color mark sensor, and draws a zigzag cut at the cursor, and the scribing action is completed. When the machine (PLC) count reaches 5, it sends a signal to the cut-off axis servo, so that the cut-off axis servo can receive the signal of the color-coded sensor, so that the signal of the color-coded sensor is connected to the cut-off axis servo action, and the package of 5 packages is packaged. carry out.
