Working principle of vertical packaging machine
For vertical packaging, it is suitable for liquids, powders and granules with good fluidity. It mainly relies on its own gravity, and when necessary, it can be completed with a certain mechanical action. Moreover, vertical packaging machines generally have two types of packaging. Function, namely, cursor cutting 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 film is cut to length, otherwise, it is cut by cursor; for pillow packaging, it is mainly suitable for single or combined 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 tube, fills the material, and seals it, and the three functions are automatically and continuously completed. The working principle is as follows: the roll film placed on the support device is wound around the guide roller group and the tensioning device. After the photoelectric detection control device detects the position of the trademark pattern on the packaging material, it is rolled into a film cylinder through the lapel former. Wrapped on 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. The vertical sealing shaft (also the film feeding shaft) of the vertical packaging machine is used as the main shaft of the system. The 3 axes of horizontal sealing, scribing, and cutting follow the main shaft. The servo controller of horizontal sealing, scribing and cutting directly grabs the film position color code signal for position detection. Heat sealing, the packaging film moves downward, the horizontal sealing shaft moves, and at the same time, the material is fed into the cylinder film and continues to move downward together. When the next cursor signal comes in, the horizontal sealing shaft moves again. 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 incision at the cursor, the marking action is completed, when the upper position When the count of the machine (PLC) reaches 5, it will send a signal to the servo of the cutting axis, so that the servo of the cutting axis can receive the signal of the color mark sensor, so that the signal of the color mark sensor is connected to the servo action of the cutting axis, and the package of 5 packages is packed.
