elt blowing is a conventional fabrication method of micro- and nanofibers where a polymer melt is extruded through small nozzles surrounded by high speed blowing gas. The randomly deposited fibers form a nonwoven sheet product applicable for filtration, sorbents, apparels and drug delivery systems. The substantial benefits of melt blowing are simplicity, high specific productivity and solvent-free operation. Choosing an appropriate combination of polymers with optimized rheological and surface properties, scientists have been able to produce melt-blown fibers with an average diameter of down to 36nm.

However, with the ever-increasing productivity, random changes in packaging parameters, these control systems have become increasingly difficult to meet the development of the new situation. At this time, a new type of technology—electromechanical integration technology came into being. It completely changed the appearance of packaging machinery and made it appear to the world in a brand-new posture.
Mechanical and electrical integration technology features
In the current era of rapid changes in science and technology, the emergence of new technologies, new processes, new materials, and new equipment is no longer the development of a single discipline, but the interpenetration of various related disciplines and various advanced technologies. And complementary results. Mechatronics technology is such a new technology. It is an integrated technology built on the basis of information theory, cybernetics, and systems theory. The essence is to use the process control principle from the system point of view to organically combine mechanical, electronic and information, inspection and other related technologies to achieve overall optimization. Specifically, it is the introduction of microcomputer technology into packaging machinery.
Mechatronics has fundamentally changed the face of packaging machinery. In this type of packaging machinery, the microcomputer serves as its brain and replaces the conventional control system. The mechanical structure is its main body and torso. Various instruments, meters, and sensors are its senses. They sense changes in various packing parameters and feed it back to the brain (microcomputer). The various actuators are its hands and feet. The necessary actions for packaging operations.
A complete electromechanical integration system generally includes microcomputers, sensors, power sources, transmission systems, and actuators. It eliminates the cumbersome and unreasonable parts of conventional packaging machinery, and integrates advanced technologies of machinery, microcomputers, microelectronics, sensors and other disciplines, and brings profound experience to packaging machinery in terms of design, manufacture, and control. The changes have fundamentally changed the face of packaging machinery.
The role of packaging machinery
A new technology, once it becomes productive, often plays a huge role. If the error of photoelectric positioning is far less than mechanical positioning, the effect of microwave drying is much better than that of electric heating drying, etc. Although the mechanical and electrical integration technology is not used for packaging machinery for a long time, the effect is obvious and the effect is huge.
Make the mechanical structure much easier
The control system is the starting organ of the machine. The traditional packaging machine control system uses relays and contactor control circuits. Its complexity increases with the increase of actuators and the increase of adjustment parts, making the machines more and more complex. Inconvenience to manufacturing, adjustment, use and maintenance. Mechatronics can replace the cumbersome electrical control cabinets and drive devices with microcomputers, sensor technologies, and new drive technologies, which can drastically reduce the number of parts and components, greatly simplify the structure, and reduce the size of the components.
Product quality improvement
There is a huge storage system in the microcomputer. People can store the parameters and related data that affect the operation of the packing machine in advance into the microcomputer. It can automatically track the production process. When one parameter or several parameters are changed, this change is fed back to the microcomputer in an instant, and the microcomputer recognizes, judges, and corrects the changed parameters in a timely manner so that the packaging machine can maintain the best working condition at any time. However, when the process parameters are changed, the traditional packaging machines rely on their experience, which makes it difficult to find the best parameters. If several process parameters are changed at the same time, it is even more inconvenient.
Such as the most common plastic bag sealing machine, its sealing quality and packaging materials, heat sealing temperature and operating speed and so on. If the material (material, thickness) changes, then the temperature and speed will also change, but it is difficult to grasp the change. If microcomputer control is used, the optimal parameters of the sealing temperature and speed of various packaging materials are matched with the input of the microcomputer memory, and the necessary sensors are combined to form an automatic tracking system. This ensures the best Sealing quality.
The more parameters are changed, the more adjustments are made, and the superiority of electromechanical integration is also greater, which is unmatched by general control methods. With more functions and higher reliability, electromechanical integration can also provide many other functions in addition to the functions of the original packaging machine. Such as soft drink liquid packaging machine, which in pneumatic, electrical and mechanical cooperation, can have box making, sterilization, filling, sealing and other functions, but if the microcomputer is introduced into the control system, it can also store such as production rate, product The data such as quantity, fault phenomenon, and cause of the fault can be processed accordingly according to the actual situation, and the result can be printed out or displayed on the screen, which greatly facilitates the operation. Mechatronics will also give the packaging machine automatic monitoring, dynamic detection, alarm and other functions, but also has security chain control, overload and out of control protection and other functions, so that the reliability of the packaging machine greatly improved.
New Mechatronics Technology Boosts Packaging Machinery Industry Updates
Packaging is a necessary condition for the product to enter the circulation field, and the main means of achieving packaging is the use of packaging machinery. With the development of the times and technological progress, packaging machinery is playing an increasingly important role in the circulation field. Most of the traditional packaging machinery use mechanical control, such as camshaft distribution, and later appeared electronic control, photoelectric control, pneumatic control and other control forms.
