Characteristics and advantages of electromechanical integration of packaging machinery

packaging is a necessary condition for products to enter the circulation field, and the main means to realize packaging is the use of packaging machinery. With the development of the times and the progress of technology, packaging machinery is playing an increasingly important role in the field of circulation. Traditional packaging machinery mostly adopts mechanical control, such as cam distribution shaft, and later there are electronic control, photoelectric control, pneumatic control and other control forms. Su Ming made a special report on "Research on new energy industry policy", but with the increasing productivity and the random variation of packaging parameters, these control systems have become increasingly difficult to meet the development of the new situation. At this time, a new technology: electromechanical integration technology came into being, which completely changed the face of packaging machinery and made it appear in front of the world in a new attitude

I. characteristics of electromechanical integration technology:

1. In the current era of rapid changes in science and technology, the emergence of various new technologies, new processes, new materials and new equipment is no longer the development of a single discipline, but the result of the mutual penetration and complementarity of various related disciplines and a variety of advanced technologies. Electromechanical integration technology is such a new technology, which is a comprehensive technology based on information theory, cybernetics and system theory. Its essence is to organically combine machinery, electronics, information, detection and other related technologies from a systematic point of view, using the principle of process control, so as to realize the overall optimization. Specifically, it introduces microcomputer technology into packaging machinery

2. Electromechanical integration has fundamentally changed the face of packaging machinery. In this kind of packaging machinery, microcomputer, as its brain, replaces the conventional control system. The mechanical structure is its main body and trunk. Various instruments, meters and sensors are its senses. They feel the changes of various packaging parameters and feed them back to the brain (microcomputer). Various actuators are its hands and feet to complete the actions necessary for packaging operations

3. The change of resistance value reflects the displacement value. A complete mechatronics system generally includes microcomputer, sensor, power source, transmission system, actuator and other parts. It abandons the cumbersome and unreasonable parts of conventional packaging machinery, and integrates the advanced technologies of machinery, microcomputer, microelectronics, sensors and other disciplines, which has brought profound changes to the design, manufacturing and control of packaging machinery, and fundamentally changed the face of packaging machinery

second, the advantages of Mechatronics on packaging machinery:

a new technology, once turned into productivity, often plays a huge role. For example, the error of photoelectric positioning is far less than that of mechanical positioning, and the effect of microwave drying is far better than that of electric heating drying. Although the time of electromechanical integration technology used in packaging machinery is not long, the effect is obvious and the role is huge. Advantages of Mechatronics on packaging machinery:

1. Greatly simplify the mechanical structure:

the control system is the starting organ of the machine. The traditional packaging machinery control system mostly uses relays and contactors to control circuits. Its complexity increases with the increase of actuator and adjustment parts, making the machine more and more complex, which brings inconvenience to manufacturing, adjustment, use and maintenance. In electromechanical integration, the cumbersome electrical control cabinet and driving device can be replaced by microcomputer, sensor technology and new transmission technology, which greatly reduces the number of parts, greatly simplifies the structure and reduces the volume

2. Product quality improvement:

there is a huge storage system in the microcomputer. People can store the parameters and relevant data that affect the work of the packaging machine in advance into the microcomputer, which can automatically track the production process. When one or several parameters change, this change will be instantly fed back to the microcomputer, which will identify and judge these changed parameters and make corresponding corrections in time, so that the packaging machine can maintain the best working state at any time. When the process parameters of the traditional packaging machine change, its adjustment is mostly based on experience, which makes it difficult to find the best parameters. If several process parameters change at the same time, it is at a loss. For example, the sealing quality of the most common plastic bag sealing machine is related to packaging materials, heat sealing temperature and running speed. If the material changes (material quality, thickness), the temperature and speed will also change, but the change is difficult to grasp. If microcomputer control is adopted, the best parameters of sealing temperature and speed of various packaging materials are matched and input into microcomputer memory, and then necessary sensors are equipped to form an automatic tracking system. In this way, no matter which process parameters are changed, the best sealing quality can be guaranteed

its important test piece is the circular ring and rectangular block made of nickel molybdenum steel. The more the composition parameters change and the more the adjustment parts are, the greater the superiority of electromechanical integration is, which is unmatched by general control methods

3. Increased functions and reliability

Mechatronics can not only maintain the functions of the original packaging machine, but also give many other functions. For example, the soft packaging machine for liquid drinks, with the joint cooperation of pneumatic, electrical and mechanical, can have the functions of box making, sterilization, filling, sealing, etc. but if the microcomputer is introduced into the control system, it can also store data such as production rate, product quantity, fault phenomenon, fault reason, etc. at the same time, these data can be processed accordingly according to the actual situation, and the results can be printed 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, as well as safety interlock control, overload and out of control protection and other functions, so that the second, third and fourth parts of the packaging machine are confirmed through fire resistance experiments, and the reliability of the classification method of installation is greatly improved

4. Simple operation and improved benefit:

the packaging machine designed with electromechanical integration technology has digital display and highly centralized display of a variety of information, greatly reducing the operation buttons and handles, and has program control and other functions. The operating procedures are greatly reduced and the operators are easy to train

most conventional packaging machines are driven by asynchronous motors. In fact, most of them are in the light load working state, which wastes a lot of energy. Electromechanical integration technology, with variable-frequency motor instead of asynchronous motor, microcomputer automatically finds the best working point, and randomly adjusts the output power of variable-frequency motor, which can generally save 40% of energy. In addition, its reliability is improved, the product quality is guaranteed, and the benefit is also improved

Mechatronics is the development direction of packaging machinery. Although it has not been applied for a long time, it has shown great advantages. With the popularization and promotion of Mechatronics in packaging machinery, it will play a positive role in the development of China's packaging industry
