Three trends in the development of China's packaging machinery industry in recent years, China's packaging machinery industry has achieved rapid development, but there have also been some low-level repeated construction. According to relevant data, compared with developed industrial countries, China lacks 25% ~ 30% varieties of food and packaging machinery products, and its technical level lags behind 15 ~ 25 years. Experts believe that the low-level repeated construction of packaging machinery has hindered the upgrading and innovation of industrial products, and should be solved by finding ways. But it can only be eliminated naturally through market regulation and strengthening the supervision of its downstream industry, the food industry. Experts predict that the future development of China's packaging machinery market will show the following characteristics:

first, the technical content of packaging machinery is increasing day by day. Some packaging machinery products in China have low technical content, while many advanced technologies have been applied to packaging machinery abroad, such as remote control technology (including monitoring), stepping motor technology, automatic flexible compensation technology, laser cutting technology, information processing technology, etc

secondly, the packaging machinery market is increasingly monopolized. At present, except for the corrugated box packaging machinery and some small packaging machinery which have certain scale and advantages, other packaging machinery in China can hardly form a system and scale. In particular, some complete packaging production lines with large market demand are monopolized by several large packaging machinery enterprises (groups) in the world packaging market

finally, the production of packaging machinery parts is specialized. The international packaging industry attaches great importance to improving the load borne by the packaging machine bones and reducing the general capacity of mechanical processing and the whole packaging system. Therefore, the specialization of the production of packaging machinery parts is an inevitable trend. Many parts are no longer produced by the packaging machinery factory, but by some general standard parts factories. Some special parts are produced by highly specialized manufacturers. The truly famous packaging machinery factory may be an assembly factory. The products are developing towards multi-function, single and high-speed polarization. The ultimate role of packaging machinery is to improve production efficiency and product diversification

new technology promotes the development of packaging machinery industry

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. The other is that the elastic modulus of elastomer changes with the change of temperature

but with the increasing productivity and the random change of packaging parameters, these control systems have become increasingly difficult to meet the development of the new situation. At this time, a new technology - mechatronics technology came into being. It completely changed the face of packaging machinery and made it appear in front of the world with a new attitude

characteristics of mechatronics technology

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 mutual penetration and complementarity of various related disciplines and a variety of advanced technologies. Mechatronics is such a new technology. It 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 system point of view, using the process control principle, so as to realize the overall optimization. Specifically, it introduces microcomputer technology into packaging machinery

mechatronics has fundamentally changed the face of packaging machinery. In this kind of packaging machinery, microcomputer, as its brain, has replaced 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 necessary actions for packaging operations

a complete mechatronics system generally includes microcomputer, sensor, power generator, 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

effect on packaging machinery

a new technology, once it becomes a productive force, 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

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 the circuit. Its complexity increases with the increase of the actuator and the adjustment parts, making the machine more and more complex, which brings inconvenience to manufacturing, adjustment, use and maintenance. As for Mechatronics, the bulky 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

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 parameter or several parameters change, the change will be immediately fed back to the microcomputer, which will identify, judge and correct these changed parameters in time, so as to keep the packaging machine in the best working state at any time. When the process parameters of traditional packaging machine change, the adjustment is mostly based on experience, which makes it difficult to find the best parameters; If several process parameters are changed at the same time, we are 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 (material and thickness) changes, 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, the best sealing quality can be guaranteed no matter which process parameter is changed

the more parameter changes, the more adjustment parts, the greater the advantages of mechatronics, which cannot be compared with general control methods. The functions are increased and the reliability is improved. The electromechanical integration can not only maintain the functions of the original packaging machine, but also endow 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. However, if the microcomputer is introduced into the control system, it can also store data such as production rate, product quantity, fault phenomenon, fault cause, etc. at the same time, it can process the data from small to large or from large to small according to the actual situation, and print the results, Or display it on the screen not only gives us the opportunity to show the extraordinary performance of our high-tech materials under extreme conditions, but also greatly facilitates the operation. Mechatronics will also endow the packaging machine with automatic monitoring, dynamic detection, alarm and other functions, as well as safety chain control, overload and out of control protection, so as to greatly improve the reliability of the packaging machine
