The Principle of the Packaging Machine

With the development of modern light industry, packaging machines are gradually appearing in our field of vision. Vertical packaging machines are one of them. It is a kind of machinery with strong packaging ability and can be applied to various small particles or powders. The physics, suitable for food and non-food, the biggest feature is the continuous packaging, which greatly saves time and labor costs.

The packaging speed of the vertical packaging machine is not only fast, but also can be automatically sealed at the same time as the packaging, and automatically cut off. It can be used not only for unbranded packaging materials, but also for high-speed packaging using materials bearing logo patterns. The general machine will make a wrong judgment due to the color on the packaging material, resulting in packaging errors. In order to eliminate the error, the design of the packaging machine must consider the problem of automatic positioning, and the continuous photoelectric positioning system is divided into the advance and retreat type, the brake type and the two transmission system synchronous type according to the error compensation working mode.

In fact, the principle of the packaging machine is very simple, it belongs to a kind of plc programmable to achieve a series of packaging actions, the packaging machine will have a set of system when it leaves the factory, the machine will strictly follow this when working Set the program to work.

First, the raw material is controlled to be cut, and then weighed. When the required weight is reached, the system automatically controls it to stop and then proceeds to the next process. After the material enters the packaging bag, the computer then controls the sealing device of the packaging bag to seal, and then the cutting device cuts the packaging bag, and the purpose of one set of packaging is reached. Moreover, the packaging system is not fixed, and the customer can adjust it according to his own needs to achieve the goal. Volkswagen’s demand for products in the food, medicine, daily necessities and other industries is increasing. Manufacturers use traditional manual packaging operations, which can no longer meet the needs of the market, and must seek equipment that produces automation and improves production efficiency. This has led to the development of a high-quality, high-performance automatic packaging machine.

Packaging machinery can be roughly divided into vertical packaging machines and pillow packaging machines. 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 sealing of the next tube bag.
