For vertical packaging, it is suitable for liquids, powders and granules with good fluidity. It mainly depends on its own gravity. When necessary, it can be completed with a certain mechanical effect. Vertical packaging machines generally have two types of packaging. Function: cutting with the cursor and fixed-length cutting. The two cutting functions are easy to switch. Which packaging method is used when the machine is running depends on the packaging film. The packaging film is roughly divided into packaging with and without a cursor and without a cursor. The film is cut with a fixed length, otherwise, it is cut with a cursor. For pillow packaging, it is mainly suitable for single-piece or combination packaging with a regular shape and sufficient rigidity.

The vertical packaging machine is a bag made of roll-shaped flexible packaging material, filled with materials, and sealed. The three functions are automatically and continuously completed. Its working principle is: the roll film placed on the supporting device is wound around the guide stick group and the tensioning device, and the position of the trademark pattern on the packaging material is detected by the photoelectric detection control device, and then rolled into a film cylinder by a lapel shaper Wrap the surface of the filling tube. First, a longitudinal heat sealer is used to longitudinally heat seal the film at the interface portion rolled into a cylinder to obtain a sealed tube, and then the cylindrical film is moved to the place of the horizontal heat sealer to perform horizontal seal to form a packaging bag tube. The metering device fills the metered articles into the packaging bag through the upper filling tube, and then heat-seals by a horizontal heat sealer and cuts in the middle to form a packaging bag unit, and at the same time forms the bottom seal of the next tube bag.

The vertical sealing shaft (also the film feeding shaft) of the vertical packaging machine is used as the main shaft of the system. The three axes of horizontal sealing, scribing, and cutting follow the main axis. The horizontal sealing, scribing, and cutting servo controller directly captures the color mark signal of the film position for position detection. After the film is formed by the molder, it becomes a tube film and performs longitudinal Heat sealing, the packaging film moves downward, and the horizontal sealing axis moves. At the same time, the material is sent into the tube film, and continues to move downward. When the next cursor signal comes in, the horizontal sealing axis moves again. Such a pack of three heat seals The action is completed. When the packaging film continues to move downward, the color mark sensor detects the color mark, the driver moves after receiving the signal from the color mark sensor, and draws a zigzag cut at the cursor. The scribe operation is completed. When the PLC (PLC) count reaches 5, it sends a signal to the cutting axis servo, so that the cutting axis servo can receive the signal of the color mark sensor. In this way, the signal of the color mark sensor is received and the axis cuts off the servo action. carry out.
